This site was chosen because of its accessibility, its importance as a foraging area, and the high incidence (almost-equal-to 50%) of fibropapillomatosis, a tumor disease of unknown etiology. Our objectives were to determine the daily movements, habitat use, and submergence intervals of normal and tumor-bearing animals. The presence of tumors had no obvious effects on movement patterns or habitat use. All turtles remained within a small portion of the bay where patch reefs and shallow coral-covered areas are common, and algal growth most abundant. During daylight, two normal and two tumor-bearing animals remained within known feeding areas, all other turtles studied stayed within deep mud bottom channels or within crevices on the sides of reefs. All, except one tumor-bearing turtle, moved up on to shallow patch reefs or shallow coral-covered areas at night. Submergence intervals for both groups were short (over 90% were 33 min or less and none exceeded 66 min) compared to maximum breath-hold times (up to 5 h) measured in the laboratory by earlier workers. Juvenile green turtles in Hawaii, therefore, most likely maintain aerobic metabolism while submerged and surface before oxygen stores are significantly depleted. Tumor-bearing turtles had a higher frequency of longer submergence intervals during the night, indicating they may have been somewhat less active at night. Normal turtles showed no such day-night difference. C1 UNIV HAWAII, HAWAII INST MARINE BIOL, KANEOHE, HI 96744 USA.

The analysis of ultrathin films by X-ray reflection confirmed a homogeneous overall film quality but did not show any Bragg reflection. However, investigation of a superstructure in terms of an alternating multilayer sample from deuterated and nondeuterated isopentylcellulose ethers by neutron reflection revealed a perfectly periodic layer structure. The influence of the degree of substitution of the isopentylcellulose ethers on the formation and structure of multilayers was investigated as well. Multilayers of partially substituted isopentylcellulose exhibit a periodical film structure composed of double layers. The perfection of the films is not influenced by the residual OH functions. The in-plane structure of tri-O-isopentylcellulose multilayers was investigated by electron diffraction in transmission geometry. The cellulose ether forms a helix of 3-fold symmetry, and the helix axes are preferentially oriented parallel to the dipping direction. Upon annealing a three-dimensional crystalline film of layered structure is obtained in which the chains are packed in a monoclinic unit cell. The very small diameter of the cellulose derivatives of less than 10 Angstrom/molecule in the layered superstructures and the observation that very perfect and homogeneously oriented multilayers are obtained by the Langmuir-Blodgett technique augment the toolbox of molecular architects interested in the rational construction of supramolecular architectures.

Our analysis is restricted to direct collisions between parallel tubes and is based on the collision dynamics worked out by Bogdan (1984). We show that there is a range of collision velocities for which neutral point reconnection of the Parker-Sweet type can occur, and a smaller range for which reconnection leads to coalescence. Mean velocities within the solar convection zone are probably significantly greater than the upper limit for coalescence. This suggests that the majority of flux tube collisions do not result in merging, unless the frictional coupling of the tubes to the background flow is extremely strong.

By combining the two sets of measurements with a new, high-resolution model of the geoid in the region, we were able to determine the cumulative 1993-1964 postseismic vertical displacement. We find uplift at all of our benchmarks, relative to Seward, Alaska, a point that is stable according to tide gauge data. The maximum uplift of about 1 m occurs near the middle of the peninsula. The region of maximum uplift appears to be shifted northwest relative to the point of maximum coseismic subsidence. If we use tide gauge data at Nikishka and Seward to constrain the vertical motion, then the observed uplift has a trenchward tilt (down to the southeast) as well as an arching component. To explain the observations, we use creep-at-depth models. Most acceptable models require a fault slip of about 2.75 m, although this result is not unique. If the slip has been continuous since the 1964 earthquake, then the average slip rate is nearly 100 mm/yr, twice the plate convergence rate. Comparing the net uplift achieved in 29 years with that observed over 11 years in an adjacent region southeast of Anchorage, Alaska, we conclude that the rate of uplift is decreasing. A further decrease in the uplift rate is expected as the 29-year averaged displacement rate is about twice the plate convergence rate and therefore cannot be sustained over the entire earthquake cycle.

Apparent equilibrium constants were measured as a function of temperature for this reaction in all four solvents. Calorimetric measurements were also performed for this reaction in aqueous phosphate buffer. The principal reaction occurring in the aqueous phosphate buffer at pH 6-7 is N-acetyl-L-phenylalanine ethyl ester(aq) + H2O(aq) N-acetyl-L-phenylalanine(-)(aq) + ethanol(aq) + H+(aq). Therefore, to compare the results for the reaction in water with those for the reaction in the organic solvents where it is assumed only neutral species are present, it was necessary to adjust the experimental results to the reaction involving neutral species: N-acetyl-L-phenylalanine ethyl ester(sln) + H2O(sln) = N-acetyl-L-phenylalanine(sln) + ethanol-(sln), where sln denotes either aqueous media, carbon tetrachloride, dichloromethane, or toluene. The values of the equilibrium constant for this latter reaction, with the concentration of water included in the expression for the equilibrium constant, ranged from 0.057 to 0.20 at T = 298.15 K for the four solvents. This rather limited range of values for the equilibrium constants is significant. The very limited amount of information available from the literature is also suggestive of the rule that equilibrium constants for hydrolysis reactions in different solvents are comparable if the reaction refers to neutral species and the concentration of water is included in the formulation of the equilibrium constant. Also, the standard molar enthalpy of reaction was found to be a linear function (slope = 313 K) of the standard molar entropy of reaction. This is indicative of an enthalpy-entropy compensation effect. C1 NIST,DIV BIOTECHNOL,GAITHERSBURG,MD 20899. NIST,DIV ANALYT CHEM,GAITHERSBURG,MD 20899.

The bulk liquid and solid phases are treated as regular solutions and an order parameter (the phase field) is introduced to describe the interfacial region between them. Two-dimensional computations are performed for ideal solutions and for dendritic growth into an isothermal and highly supersaturated liquid phase. The dependence upon various material and computational parameters, including the approach to conventional sharp interface theories, is investigated. Realistic growth patterns are obtained that include the development, coarsening, and coalescence of secondary and tertiary dendrite arms. Microsegregation patterns are examined and compared for different values of the solid diffusion coefficient.

Local enhancement occurs when fish are attracted to the site where another fish has discovered food. Experiments were conducted to determine whether fish forage as individuals when food is widely dispersed in time and space. When acclimatized to dispersed food, juvenile walleye pollock foraged as individuals and did not respond to the food discovery of others. Some fish appeared to aggressively defend areas of their tank, a behaviour not seen in fish foraging for clumped food. In a second experiment, examining the role of prior experience in fish foraging, fish were first acclimatized to clumped food and then suddenly switched to dispersed food. Fish continued to use group foraging, mediated by local enhancement, with no change over 20 food discovery events. These results indicate that social aspects of fish foraging strategies are flexible, but are also influenced by prior experience with resource distribution.

The predicted variations of the spatial-diffusion coefficient with laser intensity and detuning are in good qualitative agreement with the experimental data.

The mean front velocity has been measured and appears to be slightly slower in the presence of added gas than in vacuum. In the initial stage of expansion, this velocity is almost the same for all neutral particles in the plume in the initial stage of expansion. Velocities of neutral and ionic species have been measured by their time of arrival from the target to a quadrupole mass spectrometer and their expansion beam Maxwell-Boltzmann (MB) temperature determined. The plume electronic temperature has been determined by assuming a local thermodynamic equilibrium of the emitting species. C1 UNIV ROMA LA SAPIENZA, DIPARTIMENTO CHIM, ROME, ITALY.

A radio image of G2.4 + 1.4 was made with a resolution of approximately 0.3 pc using the VLA at 1.49 GHz. The radio source shows a thin filamentary shell of 9 x 10 pc (wind-blown bubble) superposed on a more diffuse H II region of about 13-14 pc; the radio shell extends farther to the N and W than indicated by previous radio observations. The radio morphology is in excellent agreement with the deep Her images. The radio source has a thermal spectrum. The mass of the ionized gas in the shell is about 100 M., and that of the diffuse H II region is about 150-170 M.. IRAS FRESCO images show a prominent source G2.4 + 1.4 at ah IRAS bands. The source at 60 and 100 mu m agrees in shape and position with the bright part of the optical and radio shell. If we assign the IRAS flux densities to heated dust rather than atomic lines, the mass of inferred gas is in reasonable agreement with the values derived from the 1.49 GHz data. There is a large shell-like IR feature similar to 35 pc in size with G2.4 + 1.4 and WR 102 located at its brightest and hottest edge. A thermal radio source with the Aux density similar to 0.6 mJy has been detected from the Sandage H II region 3 around the WO star in IC 1613. With a mean density of 3.5 cm(-3), an emission measure of 1.1 x 10(3) pc cm(-6) cm, and a mass of ionized gas of 2.8 x 10(4) M., this object is similar to many of the low-luminosity H II regions in the LMC. The WO star could be the only source of ionization. IRAS FRESCO images of the galaxy IC 1613 show a giant complex of dust and gas 2-3 kpc in size. This complex includes a region of active star formation with a supernova remnant, all known WR stars, and the majority of the giant H II regions in the galaxy. The southern component of the IR complex encompasses the WO nebula Sandage 3. C1 MOSCOW MV LOMONOSOV STATE UNIV,STERNBERG ASTRON INST,MOSCOW 119899,RUSSIA.

The kinetic energy of the turbulence is directly measurable, but the potential energy, which consists of magnetic, thermal, and gravitational potential energy, is largely unseen. We have extended previous results on equipartition between kinetic and potential energy to show that it is likely to be a very good approximation in molecular clouds. We have used two separate approaches to demonstrate this result: For small-amplitude perturbations of a static equilibrium, we have used the energy principle analysis of Bernstein et al. (1958); this derivation applies to perturbations of arbitrary wavelength. To treat perturbations of a nonstatic equilibrium, we have used the Lagrangian analysis of Dewar (1970); this analysis applies only to short-wavelength perturbations. Both analyses assume conservation of energy. Wave damping has only a small effect on equipartition if the wave frequency is small compared to the neutral-ion collision frequency; for the particular case we considered, radiative losses have no effect on equipartition. These results are then incorporated in a simple way into analyses of cloud equilibrium and global stability. We discuss the effect of Alfvenic turbulence on the Jeans mass and show that it has little effect on the magnetic critical mass. C1 NATL INST STAND & TECHNOL,BOULDER,CO 80309.

In this paper, the many effects of the storm will be highlighted, including perhaps the most widespread distribution of heavy snowfall of any recent East Coast storm, severe coastal flooding, and an outbreak of 11 confirmed tornadoes. A meteorological description of the storm is also presented, including a synoptic overview and a mesoscale analysis that focuses on the rapid development of the cyclone over the Gulf of Mexico. This is the first part of a three-paper series that also addresses the performance of the operational numerical models and assesses the forecasting decisions made at the National Meteorological Center and National Weather Service local forecast offices in the eastern United States.

This review illustrates 1) the difficult decisions forecasters faced when using sometimes conflicting model guidance, 2) the forecasters' success in recognizing the mesoscale aspects of the storm as it began to develop and move along the Gulf and East Coasts of the United States, and 3) their ability to produce one of the most successful heavy snow and blizzard forecasts ever for a major winter storm that affected the eastern third of the United States. The successful aspects of the forecasts include the following. 1) Cyclogenesis was predicted up to 5 days prior to its onset. 2) The unusual intensity of the storm was predicted three days in advance, allowing forecasters, government officials, and the media ample time to prepare the public, marine, and aviation interests to take precautions for the protection of life and properly. 3) The excessive amounts and areal distribution of snowfall were predicted two days in advance of its onset. 4) An extensive number of blizzard watches and warnings were issued throughout the eastern United States with unprecedented lead times. 5) The coordination of forecasts within the National Weather Service and between the National Weather Service, private forecasters, and media meteorologists was perhaps the most extensive in recent history.

ANALYSIS OF THE SCIENTIFIC BALLOONING ACCIDENT OF 2 JUNE 1924 SO BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY LA English DT Article AB During the spring of 1924, U.S. Weather Bureau meteorologist LeRoy Meisinger conducted a series of experiments with a free balloon to determine the trajectories of air around extratropical cyclones. The 10th flight in the series ended with a crash of the balloon over central Illinois. Both Meisinger and the pilot, Army Air Services Lt. James Neely, were killed. An effort has been made to reconstruct this accident using information from a review article by early twentieth-century meteorologist Vincent Jakl and newspaper accounts of the accident. The principal results of the study follow. 1) Meisinger's balloon was caught in the downdraft of a newly developed thunderstorm over the Bement, Illinois, area on the evening of 2 June; 2) a hard landing took place in a cornfield-just north of Bement, and loss of ballast at the hard-landing site was sufficient to cause the balloon to rise again; and 3) after rebounding from the ground, the balloon with the two aeronauts aboard was struck by lightning. A fire resulted that burned through the netting and led to a crash four miles northeast of the hard-landing site. C1 NEW MEXICO INST MIN & TECHNOL,SOCORRO,NM 87801.

This assumption, however, may be invalid if the abundance of the target species is high enough to saturate the gear or if the abundance of nontarget species is high enough to exclude the target species from capture. We examine a new approach to surveying fish populations with longlines that is based on time-to-capture data measured with small, fish-activated timing devices attached to every hook. A new measure of relative abundance, lambda, is developed that is immune to the effects of gear saturation and interspecific competition for hooks. Two estimators of lambda are compared by using capture-time data collected during summer 1987-1991 for pelagic armorhead (Pseudopentaceros wheeleri). Both estimators are shown to be unbiased if the underlying assumptions are true and fairly robust to the observed departures from these assumptions.

Acoustic survey data collected in the summers of 1988 and 1991 were used to test these relationships. In both surveys, mean walleye pollock abundance was highest in areas having a 70-130 m depth range and where the 50-m temperature was close to 2.5 degrees C. Thermocline depth, while not itself significant, had a significant effect on walleye pollock abundance through interactions with both bottom depth and temperature at 50 m. Walleye pollock in the top 50 m of the water column (mostly juveniles) were influenced differently by temperature and thermocline depth than the adult walleye pollock, which were generally deeper in the water column. The depth, temperature, and thermocline preferences of walleye pollock are hypothesized to be linked to food availability which is, in turn, related to temperature regimes or fronts along the Bering Sea shelf slope.

Profiles of hepatic IGF-I mRNA levels were compared with changes in growth and plasma concentrations of GH and insulin. In normally growing fish, IGF-I mRNA levels, as measured by solution hybridization-RNase protection assay, showed that hepatic IGF-I mRNA levels of yearling salmon were highest in May and June. Increased hepatic IGF-I mRNA levels followed increases in both plasma GH and insulin. Levels of hepatic IGF-I mRNA decreased in July, after a sharp decline in plasma GH in June, and remained low until the following spring. The growth rate for normal fish also decreased during fall and winter. After increases in plasma GH and insulin, which peaked in late February, hepatic IGF-I mRNA levels increased rapidly and reached a second peak in April. Increases in plasma GH and hepatic IGF-I mRNA observed in the second year were smaller and occurred earlier than in the first spring in seawater. Growth retardation (stunting) resulted from the premature transfer of cultured fish to seawater. Compared with normally growing fish, these stunted salmon had significantly higher levels of plasma GH but lower levels of plasma insulin. Hepatic IGF-I mRNA levels in stunted salmon were significantly lower, despite elevated plasma GH levels. These results indicate that hepatic levels of IGF-I mRNA in juvenile coho salmon increase in springtime, after an increase in plasma GH and insulin. These seasonal increases in GH and IGF-I precede the rapid growth period coinciding with the springtime increases in temperature and photoperiod and may therefore be associated with these environmental cues. The elevated plasma GH and reduced hepatic IGF-I mRNA levels observed in growth-retarded salmon suggested that stunted salmon may be GH resistant. Hepatic GH resistance and diminished IGF-I production may be the central endocrine defects leading to growth retardation in stunted salmon. C1 UNIV WASHINGTON, SCH FISHERIES, SEATTLE, WA 98195 USA.

To isolate natural from man-made factors, data from 60 sites with fewer than 10 000 people living within 20 km were used to test correlations between concentrations of trace elements and four candidate normalizing factors: iron, aluminum, grain size, and total organic carbon. At least 50% of the concentration variations for the elements As, Cr, Cu, Ni, Pb, Sn, and Zn can be accounted for by covariation with Fe or Al, and either of those major elements can be used for normalization. For Ag, Cd, Hg, Sb, and Se, on the other hand, no candidate normalizers accounted for more than even 30% of the variation. Based on these results, the spatial extent of contamination has been examined, and it was found that severe contamination is mostly limited to small areas near large population centers.

Initially, toxin uptake was established as a function of dose by seeding serial toxin dilutions into small aquaria containing 4-10 cm goldfish (Carassius auratus). The possibility that gills or lateral lines were principal toxin entry points was ruled out by plugging fish oesophagi with a rubber-like, dental-impression compound. Toxin uptake was reduced nearly sixfold by this procedure. Water ingestion rates were measured by exposing groups of 8-10 cm fish for varying time intervals to a constant flow of water containing 0.2% toxic supernatant from a botulinum culture. The potency of this supernatant was determined simultaneously in additional fish by intragastric inoculation. The measured ingestion rate in 8-10 cm fish was at least 0.37 ml h(-1) (with an additional 0.18 ml h(-1) entering fish either by other routes or leaking past the oesophageal plugs). Therefore, if goldfish were immersed for 2 min in a bath containing 2 x 10(10) bacteria ml(-1), their gastrointestinal tract would accumulate at least 2.5 x 10(8) bacteria.

These plots show that photoproduction rates are at a maximum at 313 nm in tropical waters and at 336 nm in Antarctic waters. Tropical surface and column rates were found to be 68 pM/day and 360 nmol/m(2)/day, respectively, and Antarctic surface and column rates were found to be 101 pM/day and 620 nmol/m(2)/day, respectively. A high degree of variability was observed between photoproduction rates from different ocean regions, with coastal rates being the highest, suggesting that natural environmental variability is an important factor. Photoproduction rates at 297 nm were found to be constant at individual locations with increasing irradiation time. Relative photoproduction rates from this work are compared to previously measured rates from coastal sea water. C1 WOODS HOLE OCEANOG INST,WOODS HOLE,MA 02543.

This suggestion is consistent with observations of increased UV-B associated with record low ozone near and around Seguin, Texas, during the summer of 1993. A sharp drop in ozone occurred during late June, and on 23 June total ozone fell to 230 Dobson units, which is 25.7% below the Nimbus-7/TOMS observed mean for June 20-24 from 1979 to 1991 (310 DU). Direct UV-B at 300 nn was the highest since ground observations were begun in February 1990. During July and August 1993, the mean total ozone was, respectively, 13% and 10.7% lower than during July and August 1990. When the Sun was not obscured by clouds or haze during July and August 1993, the mean direct irradiance at 300 nm was, respectively, 18.1% and 13.4% higher than during July and August 1990.

No attempt is made to estimate the absolute numbers or density of animals present, but the distribution and relative abundance of these three species are plotted in terms of the numbers of animals seen per kilometre surveyed. The number of animals seen is adjusted for sea state to allow for differences in detectability of cetaceans under different weather conditions. A geographical information system is used to display the sighting rates in 1-degree rectangles seasonally and for the entire year. Areas of north-western European shelf waters that appear to be most important for these three species are the western side of the northern North Sea, the Hebrides, and, for porpoises, south-western Ireland and the southern Irish Sea.

The interval between calibrations can be chosen to provide optimum time accuracy or reduced accuracy at reduced cost based on a preliminary evaluation of the statistical performance of the clock. The computer can serve as a primary network time server or can be used stand-alone whenever precise time-stamps are required.

Iodine atoms react rapidly with added I- to form I2- but do not react rapidly with O2 (k less-than-or-equal-to 10(7) L mol-1 s-1). Iodine atoms oxidize phenols to phenoxyl radicals, with rate constants that vary from 1.6 x 10(7) L mol-1 s-1 for phenol to about 6 x 10(9) L mol-1 s-1 for 4-methoxyphenol and hydroquinone. Ascorbate and a Vitamin E analogue are also oxidized very rapidly. N-Methylindole is oxidized by I atoms to its radical cation with a diffusion-controlled rate constant, 1.9 x 10(10) L mol-1 s-1. Iodine atoms also oxidize sulfite and ferrocyanide ions rapidly but do not add to double bonds. The phenyl radicals, produced along with the I atoms, react with O2 to give phenylperoxyl radicals, which react with phenols much more slowly than I atoms. (C) 1995 John Wiley & Sons, Inc.

In most commercially available systems, a zoom lens forms part of the optical configuration to suitably magnify the test optic to fill the detector. Thus, the spatial sampling conditions are variable and determined by the magnification of the optical system and the size and spatial locations of the elements of the CCD. For accurate assessment of the spatial properties of the test optic (including power spectra for example), an accurate determination of the sampling conditions must be made. A computer simulation has been developed that enables an investigation of the theoretical capabilities of sub-pixel calibration resolution. In this paper we demonstrate how sub-pixel measurements may be achieved and indicate some of the factors that influence the outcome of the measurement.

Tolerances on the profile form are specified and may correspond geometrically to surface texture parameters. One example of micrform calibration is the calibration of Rockwell diamond indenters used for hardness testing of materials. Previously reported measurement techniques do not meet the stringent microform calibration requirements for Rockwell diamond indenters. Inadequate microform calibration of hardness indenters may be one factor resulting in significant interlaboratory differences in results from Rockwell hardness tests. By using a stylus instrument, in combination with a series of calibration and check standards and calibration and measurement uncertainty calculation procedures, we have calibrated Rockwell diamond indenters in accordance with the definitions specified in ISO and ASTM standards. Our procedures for conducting microform calibration yield total measurement uncertainties less than ten percent of the tolerance values specified in ISO and ASTM standards. In this paper, the general calibration requirements, calibration and check standards, and calibration and uncertainty procedures that we use in performing microform calibrations are introduced. Some general considerations on stylus radius correction, data fitting, calibration traceability, uncertainty and reproductibility are also discussed.

DEVELOPMENT OF MODELS PREDICTING SURFACE SHELTER TEMPERATURES SO JOURNAL OF APPLIED METEOROLOGY LA English DT Article ID CLIMATE; TRENDS AB Multiple regression techniques were used to predict surface shelter temperatures based on the time period 1986-89 using upper-air data from the European Centre for Medium-Range Weather Forecasts to represent the background climate and site-specific data to represent the local landscape. Global monthly mean temperature models were developed using data from over 5000 stations available in the Global Historical Climate Network (GHCN). Monthly maximum, mean, and minimum temperature models for the United States were also developed using data from over 1000 stations available in the U.S. Cooperative (COOP) Network and comparative monthly mean temperature models were developed using over 1150 U.S. stations in the GHCN, Initial correlation analyses revealed that data from 700 mb were sufficient to represent the upper-air or background climate. Three-, six-, and full-variable models were developed for comparative purposes. Inferences about the variables selected for the various models were easier for the GHCN models, which displayed month-to-month consistency in which variables were selected, than for the COOP models, which were assigned a different list of variables for nearly every month. These and other results suggest that global calibration is preferred because data from the global spectrum of physical processes that control surface temperatures are incorporated in a global model. All of the models that were developed in this study validated relatively well, especially the global models. Recalibration of the models with validation data resulted in only slightly poorer regression statistics, indicating that the calibration list of variables was valid, Predictions using data from the validation dataset in the calibrated equation were better for the GHCN models, and the globally calibrated GHCN models generally provided better U.S. predictions than the U.S.-calibrated COOP models. Overall, the GHCN and COOP models explained approximately 64%-95% of the total variance of surface shelter temperatures, depending on the month and the number of model variables. The R(2)'s for the GHCN models ranged between 0.86 and 0.95, whereas the R(2)'s for the COOP models ranged between 0.64 and 0.99, In addition, root-mean-square errors (rmse's) were over 3 degrees C for GHCN models and over 2 degrees C for COOP models for winter months, and near 2 degrees C for GHCN models and near 1.5 degrees C for COOP models for summer months. The results of this study-a large amount of explained variance and a relatively small rmse-indicate the usefulness of these models for predicting surface temperatures. Urban landscape data are incorporated into these models in Part II of this study to estimate the urban bias of surface temperatures.

ESTIMATION OF THE URBAN BIAS SO JOURNAL OF APPLIED METEOROLOGY LA English DT Article ID AVHRR DATA; VEGETATION; MAXIMUM; LAND AB A methodology is presented for estimating the urban bias of surface shelter temperatures due to the effect of the urban heat island. Multiple regression techniques were used to predict surface shelter temperatures based on the time period 1986-89 using upper-air data from the European Centre for Medium-Range Weather Forecasts to represent the background climate, site-specific data to represent the local landscape, and satellite-derived data-the normalized difference vegetation index (NDVI) and the Defense Meteorological Satellite Program (DMSP) nighttime brightness data-to represent the urban and rural landscape. Local NDVI and DMSP values were calculated for each station using the mean NDVI and DMSP values from a 3 km X 3 km area centered over the given station. Regional NDVI and DMSP values were calculated to represent a typical rural value for each station using the mean NDVI and DMSP values from a 1 degrees X 1 degrees latitude-longitude area in which the given station was located. Models for the United States were then developed for monthly maximum, mean, and minimum temperatures using data from over 1000 stations in the U.S. Cooperative Network and for monthly mean temperatures with data from over 1150 stations in the Global Historical Climate Network. Local biases, or the differences between the model predictions using the observed NDVI and DMSP values, and the predictions using the background regional values were calculated and compared with the results of other research. The local or urban bias of U.S. temperatures, as derived from all U.S. stations (urban and rural) used in the models, averaged near 0.40 degrees C for monthly minimum temperatures, near 0.25 degrees C for monthly mean temperatures, and near 0.10 degrees C for monthly maximum temperatures. The biases of monthly minimum temperatures for individual stations ranged from near -1.1 degrees C for rural stations to 2.4 degrees C for stations from the largest urban areas. There are some regions of the United States where a regional NDVI value based on a 1 degrees X 1 degrees latitude-longitude area will not represent a typical ''rural'' NDVI value for the given region. Thus, for some regions of the United States, the urban bias of this study may underestimate the actual current urban bias. The results of this study indicate minimal problems for global application once global NDVI and DMSP data become available. It is anticipated that results from global application will provide insights into the urban bias of the global temperature record.

It is an automated network of 108 stations covering the state of Oklahoma. Each station measures air temperature, humidity, barometric pressure, wind speed and direction, rainfall, solar radiation, and soil temperatures. Each station transmits a data message every 15 min via a radio link to the nearest terminal of the Oklahoma Law Enforcement Telecommunications System that relays it to a central site in Norman, Oklahoma. The data message comprises three 5-min averages of most data (and one 15-min average of soil temperatures). The central site ingests the data, runs some quality assurance tests, archives the data, and disseminates it in real time to a broad community of users, primarily through a computerized bulletin board system. This manuscript provides a technical description of the Oklahoma mesonet including a complete description of the instrumentation. Sensor inaccuracy, resolution, height with respect to ground level, and method of exposure are discussed. C1 OKLAHOMA STATE UNIV,STILLWATER,OK 74078. NATL SEVERE STORMS LAB,NORMAN,OK 73069.

This forms the basis for a new method to discriminate between ice, water, and mixed-phase clouds. (The polarization technique often used by lidars operating in or near the visible part of the spectrum is not effective for CO2 lidars, because depolarization from ice particles is usually very small at its infrared wavelength.) The effects of particle size distribution, differential attenuation in the cloud and clear air and other sources of uncertainty on the accuracy of the two-wavelength method are evaluated. Five wavelength pairs are examined to establish criteria for designing an optimum lidar. RP EBERHARD, WL (reprint author), NOAA,ERL,ENVIRONM TECHNOL LAB,REET2,325 BROADWAY,BOULDER,CO 80303, USA.

The two new strategies were the fore-aft scanning technique (FAST) and airborne dual-platform Doppler sampling. FAST employs radar scans in cones pointing alternately fore and aft of the vertical plane that is perpendicular to the flight track. The airborne dual-platform sampling uses two Doppler radars, each aboard a separate aircraft. The Doppler radars scan strictly in the vertical plane normal to the flight track. The aircraft fly simultaneously along different, preferably perpendicular, tracks. The third strategy tested in Hurricane Gustav was single-platform sampling, which uses one Doppler radar on one aircraft that flies two consecutive, usually orthogonal, flight tracks. The antenna scans in the plane normal to the flight track. The third technique had been used previously in hurricanes and other disturbed weather. The rms differences between the aircraft in situ winds and the Doppler winds derived near the aircraft by single-platform sampling, dual-platform sampling, and FAST are found to be 7.8, 5.1, and 2.5 m s-1, respectively. These results suggest that in hurricanes dual-platform flat-plane sampling and FAST both enable substantial improvements in the accuracy and temporal resolution of airborne Doppler wind fields over those obtained from single-platform, flat-plane scanning. The FAST results should be applicable to dual-beam sampling, which began in 1991. The actual rms errors of Doppler winds far from the flight tracks, at levels well above flight level, and in highly sheared environments may be significantly higher than the above differences.

The sensor uses an open path absorption region 0.5 m long; multiple pass optics provide an optical path of 50 m. High frequency wavelength modulation methods give stable signals with detection sensitivity (S/N = 1, 1 Hz bandwidth) for methane of 65 ppb at atmospheric pressure and room temperature. Improvements in the optical stability are expected to lower the current detection limit. We used the new sensor to measure, by eddy correlation, the CH4 flux from a clay-capped sanitary landfill. Simultaneously we measured the Aux of CO2 and H2O. From seven half-hourly periods of data collected after a rainstorm on November 23, 1991, the average flux of CH4 was 17 mmol m(-2) hr(-1) (6400 mg CH4 m(-2) d(-1)) with a coefficient of variation of 25%. This measurement may underrepresent the flux by 15% due to roll-off of the sensor response at high frequency. The landfill was also a source of CO2 with an average flux of 8.1 mmol m(-2) hr(-1) (8550 mg CO2 m(-2) d(-1)) and a coefficient of variation of 26%. A spectral analysis of the data collected from the CH4, CO2, and H2O sensors showed a strong similarity in the turbulent transfer mechanisms.

It was decided to search for such variability in 100-yr time series of sea surface temperature (SST) measured aboard ships and available in the recently published Global Ocean Surface Temperature Atlas (GOSTA). Fourier and singular spectrum analyses of the GOSTA SST time series averaged over 11 subregions, each approximately 1 x 10(6) km(2) in area, show that pronounced quasi-oscillatory decadal (similar to 8-20 yr) and multidecadal (similar to 30-40 yr) timescale variability exists in the GOSTA dataset over the tropical Atlantic. Motivated by the above results, SST variability was investigated in a 200-yr integration of a global model of the coupled oceanic and atmospheric general circulations developed at the Geophysical Fluid Dynamics Laboratory (GFDL). The second 100 yr of SST in the coupled model's tropical Atlantic region were analyzed with a variety of techniques. Analyses of SST time series, averaged over approximately the same subregions as the GOSTA time series, showed that the GFDL SST anomalies also undergo pronounced quasi-oscillatory decadal and multidecadal variability but at somewhat shorter timescales than the GOSTA SST anomalies. Further analyses of the horizontal structures of the decadal timescale variability in the GFDL coupled model showed the existence of two types of variability in general agreement with results of the GOSTA SST time series analyses. One type, characterized by timescales between 8 and 11 yr, has high spatial coherence within each hemisphere but not between the two hemispheres of the tropical Atlantic. A second type, characterized by timescales between 12 and 20 yr, has high spatial coherence between the two hemispheres. The second type of variability is considerably a weaker than the first. As in the GOSTA time series, the multidecadal variability in the GFDL SST time series has approximately opposite phases between the tropical North and South Atlantic Oceans. Empirical orthogonal function analyses of the tropical Atlantic SST anomalies revealed a north-south bipolar pattern as the dominant pattern of decadal variability. It is suggested that the bipolar pattern can be interpreted as decadal variability of the interhemispheric gradient of SST anomalies. The decadal and multidecadal timescale variability of the tropical Atlantic SST, both in the actual and in the GFDL model, stands out significantly above the background ''red noise'' and is coherent within each of the time series, suggesting that specific sets of processes may be responsible for the choice of the decadal and multidecadal timescales. Finally, it must be emphasized that the GFDL coupled ocean-atmosphere model generates the decadal and multidecadal timescale variability without any externally applied force, solar or lunar, at those timescales.

In this paper, the formulation of the time-dependent numerical boundary conditions are described in a systematic way such that they can be adapted to different applications. In particular, the algorithm, which uses the boundary conditions for the solutions inside the computational domain of the test cases, is available for solving both parabolic and hyperbolic systems of partial differential equations. A numerical example for an astrophysical application in the context of photospheric shear induced dynamics is chosen to validate this new formulation. (C) 1995 Academic Press, Inc.

Groups receiving localized food displayed more aggression than those receiving dispersed food. This led to differences in growth, with fish reared on localized food having greater individual growth variability, i.e. growth depensation. However, after several months of rearing in these different feeding/social environments, fish reared on dispersed food were just as aggressive when first exposed to localized food as were fish reared on localized food. Furthermore. in competitive contests between fish of the two rearing histories, those reared on dispersed food were just as likely to become dominant as those reared on localized food. These results suggest that the behavioural development of aggressiveness is not amenable to alteration by manipulation of food distribution.

Using new tracking technology, we showed that the species (and individuals) returned to the same foraging areas during postbreeding and postmolt movements, documenting the first double migration for any animal. We also showed segregation by sex during both migrations, the causes of which are unknown. Seals dove continually to depths of 250-550 m during both migrations and travelled Linear distances of at least 18,000 (females)-21,000 km (males) during the 250 (males)-300 (females) days they were at sea. These are the longest annual migrations yet recorded for individual mammals. The double migrations apparently are modulated by the requirement for seals to return to land twice each year, to molt and to breed, although the reasons seals favor distant molting sites on the California Channel Islands over island and continental beaches nearer foraging areas are unknown.

An equation was derived to calculate the average surface oxide film thickness from the aluminum AES spectra. The oxidation of this powder was found to follow a parabolic rate law within this temperature range. The measured activation energy was 230 +/- 17 kJ/mol (55 +/- 4 kcal/mol). Analysis with x-ray photoelectron spectroscopy (XPS) showed that in addition to the nitride N 1s peak, there was a second N 1s peak. This peak has been observed in previous studies and can be attributed to N-O bonding either within the growing oxide film or at the Al2O3/AlN interface. C1 UNIV DAYTON,RES INST,DAYTON,OH 45469.

The alumina phase, 20% by volume, consisted of brick-shaped particles with a 4:1 aspect ratio embedded in a mullite matrix (mullite= 3Al(2)O(3).2SiO(2)). We took alumina elastic-constant values from the literature, and we measured mullite's elastic constants using a megahertz-frequency pulse-echo method. The two theoretical models, Datta-Ledbetter and Mori-Tanaka, proceed from very different viewpoints. The Datta-Ledbetter model uses the long-wavelength limit of a scattered plane wave ensemble-average approach. The model estimates the speed of a plane harmonic wave, averages the scattered field by the Waterman-Truell procedure and uses Lax's quasicrystalline approximation to sum over pairs. The Mori-Tanaka method proceeds by estimating the average matrix stress in a material containing ellipsoidal inclusions. For randomly oriented ellipsoids, it extends Eshelby's solution for a single ellipsoidal inclusion. Both models lack adjustable parameters. Surprisingly, the two models with different physical approaches give practically identical results. A rough check on our estimates is that they lead to correct predictions of the elastic constants of an alumina-mullite-particle aluminium-matrix composite.

BULK CONDUCTIVITY AND OFFSET RESISTANCE SO JOURNAL OF MATERIALS SCIENCE LA English DT Article ID MICROSTRUCTURAL CHARACTERIZATION; ACIS BEHAVIOR; SILICA FUME; SYSTEMS; DIFFUSIVITY AB Computer simulation of impedance spectroscopy (IS) of hydrating cement paste, using a three-dimensional, four-phase model, is described. Two puzzling features of experimental IS results, the possible offset resistance in the Nyquist plot and the sharp decrease in normalized conductivity within the first 50 h of reaction, have been studied using the computer simulation model. Insight is provided into these features using the ability of the model to compare quantitatively microstructure and properties. It is concluded that the offset resistance is an experimental artefact, and does not directly relate to microstructure. The drop in conductivity during the first 50 h is shown to be a consequence of a gradual shift from parallel-dominated to series-dominated behaviour of the electrical conductivity, as microstructural modifications take place during hydration, causing the capillary pore structure to become more tortuous. This tortuousity can also explain the high-frequency impedance behaviour in terms of a two-are response. C1 NORTHWESTERN UNIV,DEPT CIVIL ENGN,EVANSTON,IL 60208.

Using a megahertz-frequency pulse-echo method, it was verified that the composite shows little anisotropy (variation of the elastic properties with direction). Using a scattered-plane-wave ensemble-average method, we modelled the ambient-temperature elastic constants and found good model-observation agreement. To model the behaviour of the Young's modulus with temperature, Varshni's three-parameter relationship for Einstein-oscillator monocrystals was used. Again, good model-observation agreement was found. The mechanical-loss spectrum showed no remarkable features, indicating good whisker-matrix interface properties up to 732 K.

Microwave lines were assigned a measurement uncertainty of either 4 kHz (supersonic jet Fourier-transform measurements) or 50 kHz. Far-infrared lines were assigned a measurement uncertainty of 0.0002 cm(-1). A very satisfactory fit was obtained with 43 adjusted usted and 3 fixed parameters, yielding an overall weighted standard deviation of 1.04. (It must be noted, however, that microwave measurements with K greater than or equal to 13 had to be excluded from the fit.) We conclude that the existing model is capable of fitting v(t) = 0 methanol rotational transitions to experimental accuracy, provided that K values are restricted as stated above. We believe that interactions of high-K v(t) = 0 levels with low-K v(t) = I levels, leading to level shifts on the order of a few MHz, is the cause of our high-K fitting difficulties.

The data are treated by using two different methods developed with two independent assumptions due to Noyes et al. and Shedlovsky. Both methods require the knowledge of relevant ionic conductivities, which may be calculated from the Onsager limiting law. The values for K2 obtained with these two methods show excellent agreement. The value of 0.0103 mol-L-1 at 25-degrees-C agrees with the 'best' literature value of 0.0102 mol-L-1 within the experimental uncertainty, as also does the enthalpy of dissociation which is derived from the derivative of the temperature coefficient of K2.

Mechanical testing was carried out at temperatures from 25 degrees to 1500 degrees C. Matrix-cracking stress and ultimate strength of the composites were measured from load-displacement curves. They were both found to decrease with increasing temperature, but their temperature sensitivity decreased with increasing fiber-volume fraction. The tendency for noncatastrophic failure increased with fiber-volume fraction, while the tendency for catastrophic failure increased with temperature. The failure mode was demonstrated experimentally to be determined by the fiber bundle strength, S-fb, and the matrix cracking stress, sigma(c). These two parameters, in turn, were shown to be controlled by the fiber-volume fraction, f, and the temperature. failure at various temperatures was noncatastrophic when S-fb > sigma(c), and catastrophic when S-fb < sigma(c). Transition in composite failure mode between noncatastrophic and catastrophic failure was controlled via the variation of fiber-volume fraction and testing temperature. Catastrophic failure at high temperatures was found to be mainly a result of fiber strength loss. C1 UNIV MARYLAND,DEPT MAT & NUCL ENGN,COLLEGE PK,MD 20742.

The influence of weak interfaces and a rising toughness curve (T-curve) on machinability and damage modes is investigated. A profound manifestation of these characteristics is a change in the nature of subsurface damage from macroscopic fracture in the base glass to distributed microfracture in the glass-ceramic. As a result, the mechanism of material removal changes from extension of macrocracks in the base glass to microfracture and dislodgement of the mica grains in the glass-ceramic. High removal rates in scratching compare with low forces in grinding of the glass-ceramic. The removal rates and the grinding forces are found to correlate with the short-crack toughness instead of the conventional long-crack toughness. Abrasive machining of ceramics possessing weak grain boundaries and interfaces and associated rising T-curve behavior is discussed in light of these results.

As either of these two parameters is increased, the model undergoes a transition from periodic to chaotic behavior according to the universal quasi-periodicity route to chaos. Thus, the irregularity of model ENSO events and their partial locking to the seasonal cycle can both be explained as low-order chaotic behavior driven by the seasonal cycle. The chaos is due to irregular jumping of the Pacific natural ocean-atmosphere oscillator between different nonlinear resonances with the seasonal forcing. The periodic seasonal forcing seems to be the main factor determining the chaotic behavior of the model. However, the full irregularity of model ENSO events is only explained by considering additional factors, possibly including the nonlinear interaction of different delay oscillator modes related to the different model ocean Rossby modes.

In particular, these functions are easily computed and plotted in the parameter space, showing quantitatively how the cold dome width (scaled by the Rossby radius of deformation) and mountain-parallel jet speed change with the Froude number, surface roughness, inertial aspect ratio, and incident angle of the upstream inflow. The results also show that the cold dome width and mountain-parallel jet speed are insensitive to the depth of the upper-layer cross-mountain flow if the cross-mountain flow is sufficiently deep. The surface roughness and inverse inertial aspect ratio are found to have nearly the same control on the cold dome width and mountain-parallel jet speed and, thus, can be combined into a single parameter-the normalized Ekman number. The algebraic equations are shown to be useful for diagnoses or local forecasts of cold air damming provided the external parameters are properly estimated from the operational analyses or predictions. Examples of application are given for three cases of cold air damming. RP XU, Q (reprint author), UNIV OKLAHOMA,CIMMS,NOAA,100 E BOYD,RM 1110,NORMAN,OK 73019, USA.

Modifications of HPLC conditions and implementation of a median-area method for retention time determination improved and linearized a previously reported sigmoid relationship between the retention time shift (RT(shift)) of the NH4+ peak and the ratio of [(NH4+)-N-15] : [Total NH4+] in seawater fortified with (NH4+)-N-15. Increasing the temperature of the HPLC column from 47 to 85 degrees C increased mobile phase buffer flow rate relative to column back pressure, decreased the retention time for NH4+, and allowed the buffer pH to be optimized relative to the pK of NH4+. The use of median-area rather than maximum-height to define the retention time of NH4+ further improved the linearity (r > 0.995) of the relationship between the ratio [(NH4+)-N-15] : [Total NH4+] and RT(shift) over the range of isotope ratios. Reduction of NO3- to NH4+ by adding zinc dust to acidified (pH 2) seawater or lakewater samples, followed by pH neutralization, and subsequent analysis of NH4+ isotope ratios by HPLC, extended application of the method to isotope dilution experiments with NO3-. Advantages of this direct-injection method over mass-measurement approaches traditionally used for isotope dilution experiments include small sample size and minimal sample preparation.

Highest rates of community O-2 consumption and dissolved inorganic carbon regeneration were observed at intermediate (10 to 27 parts per thousand) plume salinities. Plume surface O-2 consumption rates were 2- to 4-fold greater than rates reported previously during the summer and winter. Heterotrophic bacterial production ([H-3]-leucine incorporation) was also highest at intermediate salinities and 2- to 4-fold greater than rates reported from other seasons. Net regeneration of NH4+ was observed in the 0 to 18 parts per thousand region of the plume while low rates of net NH4+ consumption were observed at 27 parts per thousand. Net NO2- regeneration in the Mississippi River suggested the occurrence of nitrification in the fresh waters of the delta. Serendipitous observations of rapid NO3- regeneration at 18 and 27 parts per thousand indicated the development of intense nitrification at intermediate plume salinities. Nitrification accounted for 20 to >50% of the community O-2 demand at 18 and 27 parts per thousand. These data indicated that nitrification was an important component of the plume nitrogen cycle and contributed significantly to oxygen consumption in the plume.

Microzooplankton grazing rates also were measured during the summer cruise. During each of the cruises, a series of stations from the Mississippi River mouth to the hypoxia region (located ca 50 to 100 km west) were sampled to examine variability of growth and loss processes along a strong environmental gradient. Significant taxa- and group-specific differences were noted for both growth and loss rates. Growth rates ranged from <0.1 to 3.0 d(-1) with highest rates in the plume region during the summer cruise, where surface rates were close to or exceeded previous mu(max), values for several taxa. For all taxa, growth rates were lower in the hypoxia region (mean = 0.5 d(-1)) than in the plume region (mean = 1.1 d(-1)); soluble nitrogen concentrations explained over 50 % of the variability in growth rates. Diatom growth rates were similar to non-diatoms in the plume region, but were significantly lower in the hypoxia region, which suggests that silica limitation may exist in this region. The fate of phytoplankton appeared to be controlled by size and by the degree of silicification. Significant microzooplankton grazing loss rates were noted only for small taxa (<20 mu m). For microflagellates, microzooplankton grazing rates averaged 82 % (range 42 to 214%) of the growth rate; sedimentation rates were always <1% of the growth rate. Sedimentation was an important loss for several diatoms, with significant taxon-specific and seasonal differences noted. Large colonial diatoms, such as Skelelonema costatum and Thalassiosira rotula, exhibited the highest sedimentation rates in the plume region during the spring cruise(0.2 to 1.0 d(-1)), whereas the lowest rates (< 0.01 d(-1)) were noted for Rhizosolenia fragilissima and Cera tulina pelagica in the hypoxia region during the summer cruise. Our results suggest that in the northern Gulf of Mexico, phytoplankton rate processes proceed very rapidly, with growth rates primarily controlled by the supply of nitrogen via the Mississippi River and the fate controlled primarily by size and density (silicification).

This represents conditions which prevail in dilute fibrous composites and serves as a first order approximation for spherical inclusion systems, like toughened polymers. The analysis elucidates the effect of the inclusion size on the anticipated strength of the matrix. It represents conditions which prevail in dilute fibrous composites as well as toughened-modified polymers. Depending largely on the elastic propreties of the pair constituents, it is found that in some cases (i.e. when matrix fracture precedes particle cavitation or matrix/fibrous debonding) the composite strength appears to be inclusion size-dependent. Specifically, it is found that when the inclusion is relatively rigid (with respect to the matrix) then an optimal inclusion size exists (scaled by the characteristic length of the intrinsic micro-cracks of the matrix) which maximizes the composite strength. When the inclusion is more compliant then its surrounding matrix, or when structural softening intervenes (like cavitation of the inclusion, debonding from the matrix, or alike) it is found that the smaller the inclusion size the larger is the strenght of the composite. The calculations are illustrated with two practical situations: highly compliant inclusion (rubber) in relatively brittle-like matrix (epoxy), and highly brittle-like inclusion (styrene-acrylonitrile copolymer, abbreviated as SAN) in compliant matrix (poly-carbonate, abbreviated as PC). Infinite rigidity (as, for instance, carbon fibers in epoxy) and zero rigidity (as, for instance, post cavitated rubber inclusion) are given as well to illustrate the two extreme limits of current actualities. A source of (possible) error in predicting the composite behavior is believed to be the residual stress that prevails in the matrix caused by thermal expansion mismatch of the two constituents, as arises after the curing process. Such calculations are added here whenever the history of the curing process is available. Various phenomenological aspects of fracture behavior, not explainable hitherto, received admissible reasoning. C1 NIST,DIV POLYMERS,GAITHERSBURG,MD.

In the present study, an intermetallic alloy with the L1(2) crystal structure, Al67Cr8Ti25, has been used to experimentally assess the predictions of the Rice-Thomson dislocation-emission model. The assessment is performed in two ways. First, model predictions of a fracture made transition at elevated temperature are compared with experimental results. Bend tests performed at temperatures in the range of 293 to 1061 K reveal that the fracture mode of Al67Cr8Ti25 changes from predominately cleavage fracture at room temperature to a mixed mode of cleavage and intergranular fracture at intermediate temperatures and then to predominately intergranular fracture at high temperatures. The observed cleavage-to-intergranular fracture transition temperature is approximately 800 K, in good agreement with the model prediction. Second, model predictions of the effect of grain orientation on the fracture mode are compared with experimental results. Electron backscatter patterns and fractographic techniques were used to analyze the grain orientations and fracture modes of grains on the fracture surfaces of specimens fractured at four temperatures in the range 439 to 1061 K. Experimental results reveal a correlation between fracture mode and slip system orientation relative to the crack, in good agreement with dislocation emission model predictions.

Results for three cases of Gloria at different states of development are presented. The hurricane's cumulative influence is identified as the differences between the hurricane and nonhurricane integrations. Throughout the integration period, area with sea level pressure differences exceeding 1 hPa in magnitude expanded in each of the three cases and was centered at the hurricane location. The influence radius of the storm, which was determined from the sea level pressure difference field, eventually reached approximately 1500 km in all cases. Comparisons of the sea level pressure differences among the three cases showed that the expansion rate differed for each case but was only weakly related to the intensity or intensity change of the particular storm. The comparisons of the wind and temperature fields from the hurricane and nonhurricane integrations indicated that the areal extent of the hurricane's influence was much larger at the upper layer than at the lower layer. A stronger anticyclonic circulation and relatively warmer temperatures developed at the upper layer in the hurricane integration compared to the nonhurricane fields. These upper-layer changes extended over an area comparable in size with the sea level pressure differences. These general features were identified in all three cases. At the lower layer, the differences between the hurricane and nonhurricane wind and temperature fields showed the impact of hurricane on the passage of a cold front over the eastern United States. Apparently, the hurricane's cyclonic circulation at the lower layer affected the movement of the front approaching from the west. The frontal passage was delayed north of the storm in the hurricane integration because of the reduction in the eastward component of the wind. To the south of the hurricane, the westerly winds were enhanced to accelerate the front movement. There were related changes in the fields of precipitation and the low-level temperature; for example, southwest of the hurricane, there was a reduction in the accumulated frontal precipitation in the hurricane integration because of the faster frontal movement.

Diabatic forcing, in conjunction with diabatic contributions in the initialization, is found to help the forecast retain the diabatic signal found in the liquid water or heating rate data, consequently reducing the spinup time associated with grid-scale precipitation processes. Both observational Special Sensor Microwave/Imager (SSM/I) and model-generated data are used. A physical retrieval method incorporating SSM/I radiance data is utilized to estimate the 3D distribution of precipitation in storms. In the retrieval method the relationship between precipitation distributions and upwelling microwave radiances is parameterized, based upon cloud ensemble-radiative model simulations. Regression formulae relating vertically integrated liquid and ice-phase precipitation amounts to latent heating rates are also derived from the cloud ensemble simulations. Thus, retrieved SSM/I precipitation structures can be used in conjunction with the regression formulas to infer the 3D distribution of latent heating rates. These heating rates are used directly in the forecast model to help initiate Tropical Storm Emily (21 September 1987). The 14-h forecast of Emily's development yields atmospheric precipitation water contents that compare favorably with coincident SSM/I estimates. In additional model experiments, explicit cloud water and rainwater fields are retained through the analysis-initialization phase of the forecast cycle, (i.e., from the end of one forecast to the beginning of the next sequential forecast). This allows the continuing forecast to resume the preforecast precipitation production where it left off, provided the mixing ratio field is modified to prevent cloud evaporation. This procedure is shown to be straightforward when grid-scale cloud water and rainwater variables are explicitly computed and retained for use in prognostic calculations.

It is shown that deep convection depends significantly on the Bowen ratio; for smaller Bowen ratio, the thermodynamic potential for deep convection increases. The elevation acid the intensity of the capping stable layer have an opposing impact on deep convection: increasing moisture accumulation through evapotranspiration was supportive but was counteracted by the enhancement of dry entrainment. Based on an approximate treatment of the effect of cloudiness on solar irradiance, it was found that development of fair weather cumulus has a secondary effect on deep convection potential. Observational and operational aspects of the influence of surface conditions on evapotranspiration and development of deep convection are presented. C1 NOAA, NSSL, NORMAN, OK USA.

This is used to provide retrospective and routine weekly analyses for the Pacific and Atlantic Oceans. Retrospective analyses have been performed for the period mid-1982 to mid-1993. The analyses are used for diagnostics of past climatic variability, real-time climate monitoring, and as initial conditions for coupled multiseason forecasts. The assimilation system is based on optimal interpolation objective analysis solved using an equivalent variational formulation. Analysis errors are estimated by comparisons to independent datasets such as temperature data from moorings and sea level information from tide gauges. In the near equatorial zone rms errors in thermocline depth are of order of 6-15 m. Comparisons of sea level estimates from the reanalyses with the records from tide gauges indicate that the rms sea level errors for monthly analysis are of the order of 0.04-0.09 m. For the weekly analyses, which potentially have more accurate forcing fields, the rms sea level errors are about 0.02-0.06 m. The analysis system can be used to infer the net heat flux at the air-sea interface on mean annual and interannual timescales. Examination of the dominant components to the oceanic heat budget shows that advection, storage changes, and the net surface heat Bur can all be of the same order of magnitude; however, frequently the net surface heat flux is much smaller than the other components. The annual variations in the components are as large or larger than the interannual variability. In the equatorial region interannual changes are of the order of 50-100 W m(-2) and act as a negative feedback to the anomalous SSTs. In the subtropics the interannual variability is only in the order of 5-10 W m(-2). Principal component analysis of the monthly analyzed ocean fields revealed an interannual sea level and SST empirical orthogonal function that has an intradecadal timescale. This mode is characterized by meridional adjustments of the thermal field. It is probably forced by the changes in the curl of the stress caused by changes in the intensity and location of the trade winds associated with the ENSO.

TI Non-Fermi liquid scaling in UPdxCu5-x (x=1, 1.5) SO PHYSICA B-CONDENSED MATTER LA English DT Article AB We have determined the inelastic magnetic response S(omega) of UPdxCu(5-x) (x = 1, 1.5) for temperatures from 0.3 K to 300 K and energies between 0.5 meV and 100 meV using the neutron time of flight technique. S(omega) is virtually identical in the two compounds, displaying marginal Fermi liquid scaling over the entire range of temperatures, as well as scale invariant energetics. C1 [Aronson, M.

For plasmid P1 DNA replication, this system activates DNA binding by the initiator protein, RepA. Activation exposes the DNA binding domain of RepA through the conversion of RepA dimers to monomers. In apparent contrast, the chaperones act after the assembly of the preprimosomal complex for phage lambda DNA replication. They remodel and rearrange the proteins within the complex to activate the DnaB helicase. The mechanism of action of DnaK, DnaJ and GrpE is, however very likely similar in both of these systems. Members of a new chaperone family, ClpA and ClpX, activate the DNA replication initiator proteins of plasmid P1 and phage lambda, respectively. They also function in the ATP-dependent degradation of these proteins in conjunction with ClpP peptidase. C1 NATL INST STAND & TECHNOL, GAITHERSBURG, MD 20899 USA.

The unique feature of this campaign was that, for the first time, scintillation enhancements were predicted in real time by observing solar events on 7-8 May, 1992 and then detected at both Ooty and Cambridge. Also, for the first time, high spatial resolution (similar to 100 sources sr(-1)) solar wind all-sky velocity maps were obtained at Ooty. Good consistency is found between the IFS observations from both observatories and in-situ shocks detected at Earth by IMP-8. Yohkoh soft X-ray images were used to infer the generation of a coronal mass ejection on 7 May, 1992. C1 TATA INST FUNDAMENTAL RES,NATL CTR RADIO ASTROPHYS,POONA 411007,MAHARASHTRA,INDIA.

Four zirconia-alumina composites (ZrO2-Al2O3) and a monolithic alumina were compared under paraffin oil lubricated wear test to investigate the effect of grain size, the residual stress and the phase transformation on the wear transitions. The tensile stress on the contact surface has been identified as the dominant stress which initiates the fracture wear of brittle materials. Wear transition occurs in the brittle materials when the tensile stress at the contact exceeds the critical value. The effect of zirconia content on the mean grain size of alumina and the wear transition resistance of the materials are presented. The dominant factors for the high wear transition resistance of ZrO2-Al2O3 composites are attributed to the fine grains with narrow size distribution within the material, the compressive residual stress on the surface due to phase transformation of zirconia and the low elastic moduli of ZrO2-Al2O3 composites. The fine grain of the composites and compressive residual stress improve the wear transition resistance, while the low elastic moduli of the composites increase the contact area and reduce the contact tensile stress. The wear transition mechanism of alumina and ZrO2-Al2O3 composites are compared by transmission electronic microscopy. During the tribological contact, ZrO2-Al2O3 composites generate dense dislocations and twins within the fine alumina and zirconia grains to absorb input energy, while monolithic alumina generates the transgranular cracks.

Near the order-disorder transition (ODT) temperature, the equilibrium cylindrical microstructure with d((100)) = 21 +/- 2 nm and cylinder diameter of about 12 nm orients in the shear field as expected based on previous reports. Above a critical shear rate and at an appropriate strain, a new shear-induced cylindrical microstructure forms. The shear-induced structure consists of grains of cylinders with a smaller diameter (8-9 nm) and a d((110)) spacing of 12 nm. The transformation which occurs, from the original p31m space group with a unit cell dimension a = 25 nm to a p3m1 space group of lower symmetry, also with a = 25 nm, is analogous to martensitic transformations. which occur in metals during deformation processes. This transformation may be a result of the preferred orientation of the original cylindrical microstructure relative to the shear field and the imposition of a nonsymmetric (simple shear) deformation.

Collocated satellite and surface measurements of solar radiation at five geographically diverse locations showed significant solar absorption by clouds, resulting in about 25 watts per square meter more global-mean absorption by the cloudy atmosphere than predicted by theoretical models. It has often been suggested that tropospheric aerosols could increase cloud absorption. But these aerosols are temporally and spatially heterogeneous, whereas the observed cloud absorption is remarkably invariant with respect to season and location. Although its physical cause is unknown, enhanced cloud absorption substantially alters our understanding of the atmosphere's energy budget. C1 NASA,LANGLEY RES CTR,DIV ATMOSPHER SCI,HAMPTON,VA 23665.

The HOBr spectrum, measured over the range 200-420 nm, consists of two absorption bands peaking near 280 nm (sigma(max) = (3.1 +/- 0.4) x 10(-19) cm(2) molecule(-1)) and near 350 nm (sigma(max) = (6.1 +/- 1.0) x 10(-20) cm(2) molecule(-1)). Atmospheric photolysis rates for HOBr calculated from these data are found to be significantly slower than previously assumed. The UV/visible absorption spectrum of Br2O, which was used as the HOBr precursor, was also recorded for the first time. The Br2O spectrum has maxima near 200 nm (sigma(max) = (2.0 +/- 0.2) x 10(-17) cm(2) molecule(-1)) and 314 nm (sigma(max) = (2.3 +/- 0.3) x 10(-18) cm(2) molecule(-1)). These spectra of Br2O and HOBr are compared with those of the analogous chlorine species. In addition, some thermodynamic properties for Br2O and HOBr have been obtained. The equilibrium constant for the reaction Br2O + H2O <-> 2 HOBr (10, -10), was determined to be 0.02, yielding Delta G(r)(o)(298 K) = 2.33 kcal/ mol for the forward reaction. This equilibrium constant is evaluated in terms of recent reports of Delta H-f(298 K) for HOBr. C1 NOAA,AERON LAB,BOULDER,CO 80309. UNIV COLORADO,COOPERAT INST RES ENVIRONM SCI,BOULDER,CO 80309.

Here we present measurements of delta(13)C made at several stations in the Northern and Southern hemispheres over the past decade. Focusing on the highest-quality data from Cape Grim (41 degrees S), which also provide the longest continuous record, we observe a gradual decrease in delta(13)C from 1982 to 1993, but with a pronounced flattening from 1988 to 1990. There is an inverse relationship between CO2 growth rate(6) and El Nino/Southern Oscillation (ENSO) events which is not reflected in the isotope record. Thus, for the ENSO events in 1982, 1986 and 1991-92, we deduce that net ocean uptake of CO2 increased, whereas during La Nina events, when equatorial sea surface temperatures are lower, upwelling of carbon-rich water increases the release of CO2 from the oceans. The flattening of the trend from 1988 to 1990 appears to involve the terrestrial carbon cycle, but we cannot yet ascribe firm causes. We find that the large and continuing decrease in CO2 growth starting in 1988(6) involves increases in both terrestrial and oceanic uptake, the latter persisting through 1992.

CTX (0.5 mouse units) induced a rapid (10-20 min) decrease in body temperature that persisted for several hours. This corresponded closely with a neuroexcitatory action of ciguatoxin on c-fos mRNA in the brain. We identified the neuronal pathways activated by CTX action in the mouse brain by immunostaining of c-fos translational product, a biomarker for neuroexcitability. c-fos-like immunoreactivity was prominent in the hypothalamus, including the medial preoptic and supraoptic nuclei. Immunostaining was also evident in certain regions of the brain stem, including the locus coeruleus, dorsolateral parabranchial nucleus, area postrema and the nucleus of the solitary tract. These studies indicate that CTX has neuroexcitatory actions on brain stem regions receiving vagal afferents and ascending pathways associated with visceral and thermoregulatory responses.

The experiment would involve ranging to a small lander placed at a high latitude on Mercury from a satellite in a near-circular polar orbit, which is accurately tracked from the Earth. These measurements can be used to determine the polar moment of inertia of the anticipated fluid outer core plus solid inner core, and thus to obtain information on the outer radius of the fluid core. Covariance analyses are carried out to assess the performance of a simulated data set consisting of 40 separate arcs with orbiter to lander ranging of about 1-m accuracy and high-accuracy Earth to orbiter ranging and Doppler tracking data. The effects of the uncertainties in a number of unestimated parameters are also considered. The force model includes the gravity field up to degree and order 14, solar tidal distortion of Mercury, and a fairly complex formulation for solar and Mercury radiation pressure on the spacecraft body and on the antenna. The total uncertainties for the estimated libration amplitude and the spin axis inclination are shown to be 0.26 and 0.03 arc seconds, respectively, for the model employed. The resulting uncertainty for the fractional moment of inertia of the core is 0.0045. Moreover, the Love number k2 can be determined with an accuracy of 0.01. Thus information on the elastic properties of Mercury's mantle also can be obtained. C1 UNIV COLORADO, DEPT AEROSP ENGN SCI, BOULDER, CO 80309 USA. NATL INST STAND & TECHNOL, BOULDER, CO 80309 USA.

These three products are known to be substrates for base excision repair enzymes involved in the reversal of oxidative DNA damage. The dependence of the yields of formamidopyrimidines on UV radiation dose was nonlinear, whereas the yield of 5-hydroxy-5,6-dihydrothymine was increased linearly in the entire dose range. Of these products, 4,6-diamino-5-formamidopyrimidine was the only compound produced in appreciable amounts at 310 nm. At the highest dose used, the formation of other pyrimidine- and purine-derived products was also observed, Their amounts, however, were increased above control levels up to 2-fold only. The hydroxyl radical scavenger dimethyl sulfoxide had no effect on product yields excluding the involvement of hydroxyl radical in product formation. 4,6-Diamino-5-formamidopyrimidine and 2,6-diamino-4-hydroxy-5-formamidopyrimidine may be produced by hydration of adenine and guanine, respectively, across the N(7)-C(8) double bond by mechanisms similar to those proposed previously for well-known formation of pyrimidine hydrates with the hydroxyl group located at C(6). Formation of 5-hydroxy-5,6-dihydrothymine indicates that hydration of thymine with the hydroxyl group located at C(5) of the pyrimidine ring also occurs, The results of these studies indicate that these monomeric base damage products could be a biologically important component of the photoproducts that are responsible for the deleterious effects of UV radiation.

Comparison spectra of two galactic remnants, Pup A and SNR G292.0+1.8 are also examined. The observations permit the determination of some important physical parameters of the N132D remnant in particular. An expansion age of 2350 +/- 520 yr is obtained, significantly greater than the similar to 1300 yr obtained by Lasker (1980). Estimates of the densities and temperatures in the observed oxygen-rich material are made on the basis of simple homogeneous slab models. The models indicate that such simple models are unlikely to be appropriate; nevertheless they do highlight the difficulties of interpretation when the diagnostic plot trends lie in similar directions to that expected from reddening effects. Line fluxes are given in raw form, and estimates of the reddening that may be applicable are given. This forms the first paper in a short series, in the second paper an excitation mechanism for the oxygen-rich material, based on an R-type ionization front model, is presented.

The NOAA-11 AVHRR/2 central wavenumber values were incorrectly specified on the launch of the satellite (Planet 1988) and in the subsequent editions of the NOAA Polar Orbiter Data Users Guide (Kidwell 1991 a, b). This Letter lists the correct values of the NOAA-11 AVHRR/2 central wavenumbers and details the differences that use of these corrected values makes to estimates of derived brightness temperature. Resultant changes in channel 3 and 4 brightness temperature are found to be insignificant but channel 5 brightness temperatures are 0.34-0.44 deg K higher than those calculated with the incorrect central wavenumbers. Updating the central wavenumbers is shown to cause 'split window' sea surface temperature estimates to decrease by 0.6-1.7 deg K whereas 'triple-window' estimates generally decrease by 0.34-0.42 deg K.

A central question regarding the mechanism of GroEL-assisted refolding of proteins concerns its broad substrate specificity. The nature of GroEL-polypeptide chain interaction was investigated by isothermal titration calorimetry using proteins that maintain a non native conformation in neutral buffer solutions. A single molecule of an unfolded variant of subtilisin BPN' binds non-cooperatively to GroEL with micromolar affinity and a positive enthalpy change. Additional calorimetric titrations of this chain with GroEL show that the positive enthalpy change decreases with increasing temperature between 6 and 25 degrees C, yielding a Delta C-p of -0.85 kcal mol(-1) degree(-1). alpha-Casein similarly binds to GroEL with micromolar affinity and a positive enthalpy change in the range of 15-23 degrees C, yielding a Delta C-p of -0.44 kcal mol(-1) degree(-1). The negative heat capacity change provides strong evidence for the role of hydrophobic interactions as the driving force for the association of these substrates with the GroEL chaperonin.

The ascent rates of the balloons were used to divide the soundings into weak and strong updrafts. All 11 soundings had magnitudes of charge densities and thicknesses of charge regions similar to those reported previously in small thunderstorms. The five weak-updraft soundings had complex charge structures of 7-9 charge regions below 10 km altitude. The magnitude of the maximum measured electric field in these soundings was 100-150 kV m(-1). The four soundings in strong updrafts had balloon ascent rates of at least 15 m s(-1) for at least 1 km. These soundings had simpler electrical structures of 3-5 charge regions below 10 km altitude. Their maximum measured electric fields ranged from 85 to 130 kV m(-1). The data may support an earlier hypothesis that charge is elevated in strong updrafts. In addition, the data may suggest that simpler charge structures are associated with proximity to strong updrafts rather than with different storm types.

These calculations were performed by incorporating knowledge of direct global warming potentials with an evaluation of the relationship between tropospheric cooling from stratospheric ozone loss and tropospheric halocarbon mixing ratios. The indirect cooling effect is strongly dependent upon the effectiveness of each halocarbon for ozone destruction. Strong net cooling is ascribed to additions of bromocarbon gases, while methyl chloroform and carbon tetrachloride are more nearly climate-neutral, and the CFCs and HCFCs display strong net warming. Consideration of indirect cooling also has important implications for the expected future net halocarbon forcing of the climate system: in the next 20 years, halocarbon radiative forcing is not predicted to decrease as mixing ratios of strongly ozone-depleting gases decline because of faster decreases in radiative cooling than in radiative wanning. Furthermore, continuing production of HFCs as substitutes for CFCs could result in sharply increasing halocarbon radiative heating in the latter part of the 21st century because of the increasing atmospheric burden of these compounds.

Laboratory measurements of the pertinent reaction rates were carried out at thermal energy for free electrons and for the atmospheric ions O+, O-2(+) O-2(-), O-2(-), NO+, H3O+, NO3-, and CO3-. Atmospheric removal by electrons reduces the lifetimes of c-C4F8 and SF6 from about 3200 years to 1400 and 800 years, respectively, only if the respective product anions C4F8- and SF6- do not subsequently regenerate the parent neutral compounds. Atmospheric removal by ion reactions is minor or negligible, with the largest effect (similar to 5%) being removal of C6F14 by O-2(+). Removal of CF4 and C2F6 by O+ is probably the most important single destruction process in the atmosphere for these two compounds, but their lifetimes are governed by removal at the Earth's surface in high-temperature combustors. While we show that the lifetimes of c-C4F8 and SF6 may be significantly shorter than previously estimated, these compounds remain extremely long-lived with significant global warming potentials.

Direction of water flow on the continental shelf Varies with depth, allowing the potential for enhancement of shoreward transport by behavioral depth regulation, possibly in response to vertical salinity gradients. Salinity profiles from the North and South Carolina continental shelf were analyzed to quantify the salinity gradients in the field. Behavioral response to salinity was investigated by exposing laboratory spawned and reared menhaden and spot larvae of different ages to rates of salinity change in an experimental apparatus in the laboratory, At each rate of salinity change tested, five replicate runs were recorded each with groups of 30 to 50 larvae, Both species and age groups showed a significant ascent response upon salinity increases, Rates of increase of 0.28 and 0.13 x 10(-1) ppt.min(-1) with absolute salinity increases of 0.8 and 0.3 ppt were thresholds for response by young (4-13 days post-hatching) and old (2-4 wk post hatching) menhaden larvae, respectively. For spot, rates of increase of 1.15 and 0.85 x 10(-1) ppt.min(-1) with absolute salinity increases of 1.4 and 2.0 ppt were thresholds for response by young and old larvae, respectively. Response to decreasing salinity was absent in both species, thus decreasing salinity with depth would not cause larvae to descend. In nature, salinity gradients of sufficient magnitude for depth regulation, and possibly facilitating cross-shelf transport appear common for menhaden, but not for spot.

The technique involved spin labeling poly-(acrylic acid) probe molecules of various sizes to serve as sensors which were mixed into the concentrated polyelectrolyte solution. When probe molecules were smaller than the mesh size of the polyelectrolyte solution, the local rotational correlation time (RCT) of the spin label was essentially unchanged from free solution. When the mesh size approached or was smaller than the probe size, the RCT was altered due to close-range interactions between the probe molecule and neighboring polymer chains. The smallest size probe that interacted with a polymer matrix was used as the basis for quantifying mesh sizes. There was reasonable,agreement between theoretical estimates of mesh sizes in collagen solutions and estimates from the experimental technique. Measured mesh sizes in hyaluronic acid solutions show good quantitative agreement with reported mesh size calculations from measured probe diffusion rates in similar matrices.

Three normal mode vibrations are studied with band origins at 963.4, 980.2, and 1025.2 cm(-1). The 963.4 cm(-1) band is well characterized by an asymmetric-top Hamiltonian, except for the presence of a weak perturbation for J' = 7, K'(a) = 2 affecting only the A-symmetry internal-rotor state. Microwave-infrared double resonance is used to study the microwave spectrum of the perturbing or 'dark' state. The observed dark-state K-doublet asymmetry splittings and rotational-state selection rules indicate that the perturbing state has five quanta of excitation in the torsional mode (nu(21)) built upon the A''nu(19) fundamental. The precise frequency determined for 5 nu(21) of 421 (2) cm(-1) leads to the first accurate determination of the barrier to CF3 internal rotation as 641 (5) cm(-1). In contrast to the 963.4 cm(-1) vibration, the 980.2 and 1025.2 cm(-1) modes show a large number of J' and K'(a) perturbations which differentially affect the A and E symmetry internal-rotor states. The magnitude of the perturbation-induced A/E splittings indicate that the perturbing states must have at least four quanta of torsional excitation. The present results suggest that high-order vibrational interactions are important in the vibrational dynamics of molecules at low levels of overall vibrational excitation.

The availability of the U.S. Navy's SOund SUrveillance System (SOSUS) for environmental research has allowed the continuous monitoring of low-level seismicity of the Juan de Fuca Ridge in the northeast Pacific. On June 22, 1993, NOAA installed a prototype system at U.S. Naval Facility Whidbey Island to allow real-time acoustic monitoring of the Juan de Fuca Ridge using SOSUS. On June 26, 2145 GMT, a burst of low-level seismic activity, with accompanying harmonic tremor, was observed and subsequently located near 46 degrees 15'N, 129 degrees 53'W, on the spreading axis of the Juan de Fuca Ridge. Over the following 2 days, the activity migrated to the NNE along the spreading axis with the final locus of activity near 46 degrees 31.5'N, 129 degrees 35'W. The nature of the seismicity was interpreted to represent a lateral dike injection with the possibility of eruption on the seafloor. Based on this interpretation, a response effort was initiated by U.S. and Canadian research vessels, and both warm water plumes and fresh lavas were subsequently identified at the site.

The swarm started near 46 degrees 15'N and migrated northward over the next 40 hours to similar to 46 degrees 36'N, where the majority of 676 events occurred during the following 3 weeks of activity. The earthquakes propagated NNE at a velocity of 0.3 +/- 0.1 m s(-1) from the southern to northern swarm sites. The activity went undetected by land-based seismic networks along the Oregon and Washington coasts, suggesting that the earthquakes were all M less than or equal to 4.0. The character of this earthquake swarm is very similar to dike injections observed at Krafla and Kilauea Volcanoes. The earthquake activity and subsequent migration probably represent a lateral dike injection into faults and fissures comprising the CoAxial segment. The reservoir acting as the dike's source likely resides beneath, or to the south of, the initial southern swarm of earthquakes. The large magma supply at Axial Volcano cannot be ruled out as the source for the CoAxial dike, even though Axial Volcano exhibited no earthquake activity related to the CoAxial swarm. The T-wave earthquake swarm reported here is the first deep-ocean observation of volcanic seismicity associated with what most likely was a mid-ocean ridge dike injection event.

The activity migrated 60 km along the crest, suggesting a lateral dike injection and the possibility of a volcanic eruption. Subsequent geologic and oceanographic investigations confirmed that an eruption had taken place. Examination of the individual acoustic arrivals shows changes in the character of the signal that are consistent with an injection of magma. A reduction in the rise time of the wave packet and a proportional increase in high frequency energy was observed and is interpreted to result from a shoaling of the earthquake source region. Second, the source magnitudes were largest at the onset of the swarm and became smaller over time, also consistent with shoaling of the dike. The appearance of the T-wave arrivals changed significantly 5 days after the beginning of the swarm, potentially indicating the onset of a surface eruption.

A rapid response utilizing a CTD/rosette/chemical scanner and a remotely operated vehicle occurred in the month following the T-wave swarms. The pattern of T-wave events and water-column anomalies (including several event plumes) are remarkably coincident. The only known eruptive area is at the northern swarm area, where a very fresh pillow lava ridge was discovered, mapped, and sampled with the remotely operated vehicle ROPOS. A vent area about 22 km south of the lava flow was emitting large quantities of bacterially generated floccular material. The temporal pattern of T-wave events and the coincidence between the T-wave swarms, the young lava flows, and hydrothermal plumes suggests that there is a close analogy between this activity and lateral dike injections such as have been closely monitored at Icelandic central volcanoes.

A rapid field response to the acoustic detection of seismic activity on the CoAxial segment of the Juan de Fuca Ridge, June/July 1993, provided the opportunity to conduct a unique series of observations of hydrothermal event plumes. Between July 3 and 26 we detected at least three event plumes ranging in plume volume from 1.3 to 4 x 10(10) m(3), and in excess heat from 2.2 to 12.4 x 10(15) J. Two were discovered directly above a new lava extrusion. One of these was first sampled within days of its release, as evidenced by its asymmetric shape, complex structure, and a steadily increasing light attenuation anomaly apparently generated by ongoing precipitation of hydrothermal Fe. We hypothesize that event plumes were produced intermittently in response to successive volcano-tectonic events that produced pulses in seismic activity between June 28 and July 14.

A comprehensive view of Mn and Fe liberated as hydrothermal discharge during this volcano-hydrothermal event was obtained as part of a rapid field response that included continuous in situ measurements of Mn and Fe. Distribution maps for Mn, Fe and temperature anomaly within the chronic and event plumes reveal significant thermochemical diversity that we ascribe to variable extraction efficiencies for heat and metals by source fluids, and to plume age differences. The Mn/heat data suggest that diffuse fluids could be the primary source of the chronic plume at northern CoAxial segment but make only a minor contribution to event plumes. Measurements of ephemeral Fe(II) were used to estimate that the event plumes were similar to 2, similar to 4, and >6-8 days old when first sampled, corresponding to formation times during peak seismic activity. The inventories of Mn and Fe within the three CoAxial event plumes were similar to values previously reported for megaplumes. C1 FISHERIES & OCEANS CANADA,INST OCEAN SCI,SIDNEY,BC V8L 4B2,CANADA.

The event plumes residing similar to 600 m above the seafloor had ''normal'' SHemeat ratios averaging 0.34 x 10(-12) cm(3)STP cal(-1), while the deeper, steady-state plumes had elevated He-3/heat values ranging from 0.6 to 4.5 x 10(-12) cm(3)STP cal(-1). These results generally confirm that elevated He-3/heat ratios in some of the water-column plumes are a reliable indicator of a recent magmatic/tectonic event. However, in contrast to the 1986 JdFR event, there was no evidence for hydrothermal activity on the CoAxial segment prior to 1993, thereby requiring revision of our models for event plume generation.

Here these issues are investigated using a three-dimensional non-hydrostatic hydrodynamical model. The model treats the case of a starting plume from a finite-length, narrow line source of heat ascending into a rotating environment stratified in temperature and salinity. The developing water column plume is studied over an initial time period of approximately f(-1), where f is the Coriolis frequency. Midway into this interval the plume attains its maximum rise height of similar to 900 m, for given buoyancy flux and stratification conditions. Thereafter, the plume spreads laterally and the effects of the earth's rotation come into evidence. Outward flow at 400-900 m above bottom is primarily transverse to the line source, quickly making the plume at those heights more circular than line-like.

Record-averaged flow was about 2 cm/s across axis, which is sufficiently large to advect plumes off axis in a few days. During July two megaplumes (1800 m level) disappeared between repeated CTD rows. A deeper plume (2150 m) had a relatively strong signature during August and extended southeastward in agreement with the observed flow. A CTD tow along the east flank of Axial Volcano did not locate remnants of the megaplumes but did find deeper plumes which could have come from off-axis advection from the CoAxial sources followed by southward advection along the east side of ridge.

Linear theory misses the transition to the asymmetrical configuration that produces the enhanced drag. Steady-state nonlinear models rely on an ad hoc upstream condition like Long's hypothesis and can, as a result, be inconsistent with the flow established naturally by transients, especially if blocking is involved. Numerical solutions of the stratified initial Value problem have left considerable uncertainty about the upstream alteration, especially as regards its permanence. A time-dependent numerical model with open boundaries is used in an effort to distinguish between permanent and transient upstream flow changes and to relate these to developments near the mountain. A nonrotating atmosphere with initially uniform wind and static stability is assumed. It is found that permanent alterations are primarily due to an initial surge not directly related to wave breaking. Indeed, there are no obvious parameter thresholds in the time-mean upstream state until ''orographic adjustment'' (deep blocking) commences. Wave breaking, in addition to establishing the downstream shooting how, generates a persistent, quasi-periodic, upstream transience, which apparently involves the ducting properties of the downslope mixed region. This transience is slow enough to be easily confused with permanent changes. To understand the inflow alteration and transience, the energy and momentum budgets are examined in regions near the mountain. High drag conditions require permanent changes in Row force difference across the mountain and, consequently, an ongoing horizontal flux of energy and negative momentum. The source of the upstream transience is localized at the head of the mixed region. Blocking allows the total drag to exceed the saturation value by more than an order of magnitude. The implications for nonlinear steady-state models and wave drag parameterization are discussed.

Of particular interest are modes that correspond to a recurring pattern concentrated in the Western Hemisphere with a period of about 25 days reported by Branstator and Kushnir. The most unstable modes of November-March means from individual years tend to be westward propagating and have a structure that is similar to the observed 25-day pattern. By following the evolution of each Rossby-Haurwitz mode as the basic state is gradually changed from a state of rest to an observed mean state, it is demonstrated that all but about eight of the Rossby-Haurwitz modes will be modified beyond recognition by the action of the time mean flow. One of these, the second gravest antisymmetric zonal wavenumber-one mode (denoted {1, 3} and sometimes referred to as the IB-day wave), has a structure that bears some resemblance to the observed 25-day pattern, but it is typically neutral. The structural similarity between this mode and the 25-day pattern is not as pronounced as the similarity between the most unstable modes and the 25-day pattern. Furthermore, the mode for the observed basic state that {1, 3} evolves to depends on the path by which the resting state is transformed into the observed state, suggesting that {1, 3} cannot always be thought of as a distinct mode in the presence of a realistic background. The results indicate that even if {1, 3} can be considered to exist in wintertime mean flows, it is distinct from the most unstable modes on those flows. By slowly changing the basic states that support the westward propagating unstable modes until they are equal to the climatological January state that earlier studies have shown produces quasi-stationary teleconnection-like modes, it is demonstrated that the unstable westward propagating and quasi-stationary modes are related to each other.

A nonhydrostatic, two-dimensional version of the Colorado State University Regional Atmospheric Modeling System (CSU-RAMS) is used to deduce the impact of east-west variability of soil moisture and vegetation on convective boundary layer evolution and dryline formation. The effects of the initial moisture and wind fields and the impact of the Coriolis force on the model results are also examined. Model output is compared with special airborne and sounding observations of the 24 May dryline. Several findings of an earlier observational study of the 24 May dryline are supported in the present study. The modeled drylines are broadly comparable to the observed dryline with respect to the following properties: 1) width, 10 km; 2) strong horizontal moisture and virtual potential temperature gradients, >4 g kg(-1)/10 km and 2 KI 10 km; 3) strong horizontal convergence, updraft, W-E shear of N-S wind component, 8 X 10(-4) s(-1) 1 m s(-1), 10 m s(-1)/10 km, respectively; 4) bulges of moisture and N-S wind component above the surface dryline location (due to combination of vertical mixing and vertical advection); and 5) elevated moist layer east of the dryline during late afternoon (due to eastward advection of the moisture bulge). A rather diffuse dryline begins to form by about noon from the combined effects of strong vertical mixing of moisture and westerly momentum to the west of the dryline. Convective boundary layers (CBLs) of differing depths develop on either side of the dryline, giving rise to horizontal airflow acceleration in low levels via a mesoscale hydrostatic pressure gradient east of the dryline. A vorticity dynamics analysis indicates that a horizontal virtual potential temperature gradient causes strong solenoidal forcing of horizontal vorticity (order 10(-5) S-2) and a thermally direct vertical circulation that concentrates at the dryline. Low-level winds east of the dryline decelerate, generating convergence and resulting in the development of an easterly, subgeostrophic airflow component during midafternoon. Strong convergent frontogenesis contributes to rapid development of the horizontal thermal gradients at the dryline during middle to late afternoon. For example, convergent and net frontogenesis of Vapor mixing ratio achieves order 10(-7) g kg(-1) m(-1) s(-1). Ageostrophic forcing helps maintain a low-level southerly jet east of the dryline during the daytime via the Coriolis term. Virtual temperature differences across the dryline during late afternoon, implying virtual density differences, are consistent with the notion that the dryline propagates relative to the ambient westerly shear according to the theoretical phase speed of a density current. The formation of the dryline and the evolution of the CBL are sensitive to the east-west profile of sensible heating, which in turn is sensitive to the soil moisture. A west-to-east change of volumetric soil moisture from 0.35 to 0.5 over 50 km (0.15/50 km), resulting in a sensible heat flux gradient in the surface layer of about 100 W m(-2)/50 km, is sufficiently large to cause a dryline to form. Drylines do not form in test cases where volumetric soil moisture is horizontally homogeneous with values of 0.5 or 0.35. A mesoscale convergence line, characterized by a strong updraft collocated with a weak moisture gradient, forms in the latter case. Horizontal variations of sensible heat flux in the surface layer are accentuated by vegetation contrasts, causing additional sensitivity of CBL and dryline evolution.

Such behaviour is shown, for example, by electron-positron pair cascades and the time evolution of relativistic proton distributions in dense radiation fields. Three independent techniques have been developed to simulate these non-linear problems: the kinetic equation approach; the phase-space density (PSD) Monte Carlo method; and the large-particle (LP) Monte Carlo method. In this paper, we present the latest version of the LP method and compare it with the other methods. The efficiency of the method in treating geometrically complex problems is illustrated by showing results of simulations of 1D, 2D and 3D systems. The method is shown to be powerful enough to treat non-spherical geometries, including such effects as bulk motion of the background plasma, reflection of radiation from cold matter, and anisotropic distributions of radiating particles. It can therefore be applied to simulate high-energy processes in such astrophysical systems as accretion discs with coronae, relativistic jets, pulsar magnetospheres and gamma-ray bursts.

Gallagher and Pritchard have given a simple two-state model for such collisions which includes a radiative transition or a single curve crossing at short range representing, for example, fine-structure-changing collisions. In order to better describe the more complicated case found in alkali metals, we have extended this model to include several excited hyperfine structure levels with curve crossings at long range. We find that collisions in a laser field that are capable of expelling atoms from the trap can be suppressed in some laser frequency regions and enhanced in others, in comparison with the predictions of the simple two-state model. Using this model to represent radiative escape via the 2u potential of alkali dimer molecules we are able to greatly improve agreement between theory and experiment, including new measurements on Rb-85 reported here.

A looplike magnetic cloud is modeled as a gigantic flux rope that moves through the magnetized medium of the solar wind. The dynamics of a model cylindrical magnetic cloud is used to elucidate the motion of magnetic clouds and their expansion in interplanetary space. Previous models of magnetic clouds with the assumption of either force-free magnetic field or magnetohydrostatic equilibrium preclude the consideration of motion. The dynamical model, based on flux rope dynamics, allows the inclusion of forces that drive the motion of the magnetic clouds relative to the solar wind. C1 NOAA,SPACE ENVIRONM LAB,BOULDER,CO.

There is a formal resemblance to two-dimensional flow, with surface temperature playing the role of vorticity, but a different relationship between the flow and the advected scalar creates several distinctive features. A series of examples are described which highlight some of these features: the evolution of an elliptical vortex; the start-up vortex shed by flow over a mountain; the instability of temperature filaments; the 'edge wave' critical layer; and mixing in an overturning edge wave. Characteristics of the direct cascade of the tracer variance to small scales in homogeneous turbulence, as well as the inverse energy cascade, are also described. In addition to its geophysical relevance, the ubiquitous generation of secondary instabilities and the possibility of finite-time collapse make this system a potentially important, numerically tractable, testbed for turbulence theories.

This review traces the development of the study of seafloor hydrothermal systems from the indirect evidence provided by conductive heat flow anomalies to the discovery of approximate to 350 degrees C black smoker vents on the East Pacific Rise at 21 degrees N. Although the review focuses on physical characteristics and processes, it outlines some key characteristics of vent fluid chemistry that provide constraints on physical models. Ridge crest systems have thermal power outputs ranging from 10 to 10(4) MW. They are transient systems, driven by magmatic heat sources, but episodic events such as megaplumes, the interplay between focused and diffuse venting, and other aspects related to their thermal, chemical, and biological evolution remain poorly understood. Advances will be made by continuing exploration and discovery to determine the full range of possible phenomena both on and off axis and in different tectonic settings. In order to understand the complete, integrated ridge system, however, future studies must include long-term monitoring of an active system, deep drilling into the reaction zone, and mathematical modeling that incorporates both physical and chemical constraints.

The study focuses on the H concentration regime (less than or equal to 4.8 at. % H) where, at room temperature, no precipitation of the H in a hydride phase (beta-phase) was observed. In this concentration regime, the solubility measurements show an enhanced H solubility relative to coarse-grained Pd. The neutron-scattering experiments show that this additional H is incorporated in the grain boundaries and at the surface of the grains. Surface modes of H at similar to 90 and 120 meV were identified. Compared to coarse-grained Pd, no change in the H solubility was found for the crystal lattice of the nanosized grains.

These results are consistent with cooling of rising fluids and precipitation of various metal sulphide, sulphate and oxide phases in situ within the sediment column, prior to expulsion of the fluids from the seabed. Significant enrichments of Mg and U, elements which are quantitatively removed from high-temperature vent-fluids, are also observed in the Escanaba Trough sediments, however. Enrichments of these elements cannot derive from simple conductive cooling of the rising vent-fluids but, instead, are believed to result from extensive seawater-metasomatism as relatively fresh unreacted seawater is heated from below by hot sediments and/or percolating vent-fluids in the upper levels of the circulation system. Calculated seawater/sediment interaction ratios range from similar to 5:1 to 25001 of seawater per gram of sediment. Pb, Sr and Nd isotope distributions for the Escanaba sediments are consistent with combined sediment-fluid and seawater-sediment interactions. Pb isotope ratios for hydrothermal and background sediments coincide with local sulphide deposits but are much more radiogenic than local MORE. This indicates not only that complete isotopic re-equilibration must occur between the hot, rising fluids and the host sediments but, in addition, that sediment composition appears to dominate the Pb isotopic composition of these fluids. Sr and Nd isotope ratios in the hydrothermally altered sediments, which are distinct from background ratios, coincide closely with modern seawater values, providing confirmatory evidence that extensive interactions must also have occurred between these hydrothermal sediments and relatively fresh, unreacted seawater.

Simulation was based on the Mie scattering calculations of the ASASP's response to input lognormal size distributions of particles having different refractive indices. Results from such simulation calculations show that the measurement data would greatly distort the true size distributions with apparent artificial peaks and underestimation of particle volume, especially in the resonant region of the instrument's response, 0.4-0.8 mu m particle diameter size range. Thus it is very important in interpreting the size distribution data measured with an ASASP to correct them using the size calibration data based on the optical properties of the particles being measured.

Results were compared to a conventional enzymatic colorimetric procedure and to the definitive method, which is based on isotope dilution mass spectrometry. Fluorescence detection enhances sensitivity over current colorimetric methods by approximately two orders of magnitude, and the assay response is linear over three orders of magnitude of cholesterol concentration. The reaction is performed in a single step and can be performed with small sample (1 mu l) and reaction (200 mu l) volumes. The fluorescence intensity is stable after a 30-min sample incubation at room temperature. The sensitivity of this fluorescence assay makes it possible to measure subnanomoles of cholesterol, allowing accurate measurement of total cholesterol in 1 mu l of serum or less. This level of sensitivity will also allow measurement of cholesterol in various isolated lipoprotein fractions. (C) 1995 Academic Press, Inc. C1 NIST,CHEM SCI & TECHNOL LAB,GAITHERSBURG,MD 20899.

The glucose oxidase/glutamate oxidase/lactate oxidase was immobilized on silanized controlled pore glass particles and packed into a Teflon column (i.d., 1.2 mm; length, 40 mm) to give a bed for glucose/lactate/glutamate. The hydrogen peroxide formed by the enzymatic reaction in the packed bed was monitored by a horseradish peroxidase- and tetracyanoquinodimethane (TCNQ)- modified graphite paste electrode at 50 mV vs Ag/AgCl. The glucose oxidase/lactate oxidase/glutamate oxidase were regenerated in the packed bed, whereas peroxidase was regenerated in the TCNQ-mediated graphite paste electrode by the oxidation of TCNQ. The oxidized TCNQ was electrochemically reduced at 50 mV vs Ag/AgCl. The cathodic current obtained by the reduction of TCNQ determined the concentration of the injected analytes in the packed bed. The system showed very rapid response. Response curves for the analysis of peroxide, glucose, lactate, and glutamate are reported. (C) 1995 Academic Press, Inc.

The fluorescence measurements are accomplished with a fiber optic probe. Seven different mixtures were examined in this study. Each one contained a nonfluorescent base of nutrients and salts along with one of the following media ingredients at 5 g/100 mL: cottonseed flour, corn gluten meal, soybean flour, distiller's grains and solubles, corn steep liquor, brewer's yeast, and molasses. The concentration of tetracycline was varied in each mixture and fluorescence measurements were made at every concentration step. Excitation light of 390 nm was used to probe the samples, and emission spectra were obtained over the wavelength range from 400 to 600 nm. In most of the samples studied, the fluorescence intensity in the wavelength range corresponding to background media fluorescence (420-480 nm) decreased as the tetracycline concentration increased. The decreases in the short wavelength range might be explained by the absorption by tetracycline of 390 nm excitation light (in competition with absorption by the media) and/or by absorption of background media fluorescence by tetracycline. Frequently, the maximum emission of the mixtures shifted to longer wavelengths. The maximum approached that of tetracycline (approximately 520 nm). Plots of integrated fluorescence intensity, in the emission wavelength regions of 420-480 nm and 500-560 nm, versus tetracycline hydrochloride concentration reflect these shifts. We have found that the changes in fluorescence intensity in these two wavelength regions during tetracycline addition depend on the identity of the media component in the mixture. For corn meal, soybean, brewer's, and molasses media, the fluorescence in the short emission wavelength range decreases while that in the long region increases. In the case of distiller's and corn steep media, the fluorescence changes very little during tetracycline addition.

The data show that fluorescence can be used to detect tetracycline, at least qualitatively, in the presence of the highly fluorescent media ingredients.

Colliding neutral atoms, confined in a laser trap, are photo-associated to bound excited states of the dimer molecule by absorbing a photon from a tunable laser. The technique can probe long range and ''purely long range'' molecular states that are difficult or impossible to detect by traditional means and, because of the extremely low energy of the colliding atoms ( < 1 mK), is capable of high resolution ( < 0.001 cm(-1)). The spectra are useful for atomic lifetime measurements, determination of atomic ground-state scattering information, and measurement of curve-crossing probabilities. Theoretical and experimental work in the field, including multiple resonance techniques and photoassociation line shapes, are reviewed.

By application of external optical feedback, we have narrowed the diode-laser linewidth by two orders of magnitude, yielding a spectral width of less than 200 kHz. The diode- laser frequency is stabilized and controlled via the external reflector by variable-frequency offset-locking the diode-laser to a CO laser frequency. This substantial improvement in the spectral properties enabled us to perform a Lamb-dip experiment on a carbonyl sulfide (OCS) absorption line near 1985 cm-1. We were able to detect a saturated dispersion signal at low pressure (5 Pa) with a signal-to-noise ratio of several thousand. The present paper describes the unique features of the optically stabilized tunable diode-laser system and its use as a spectroscopic tool for sub-Doppler applications.

In the absence of a ground plane, simulations show that junctions larger than about 4 times the Josephson penetration depth are of limited utility because the microwave power required to induce Shapiro steps increases rapidly with junction size.

The basic cell consists of two Josephson junctions enclosed in a microstrip resonator which provides in-phase synchronization and low dynamic resistance in the current-voltage characteristic. Synchronization of the ten junctions was observed up to 45 K and up to 1 THz.

We use wide junctions that are in situ deposited on top of PdAu resistor films (to minimize inductance) and are situated above Nb ground planes to ensure uniform current injection. From the measured parasitics, we infer the maximum power and frequency that can be obtained for critical-current densities J(c) less than or equal to 100 kA/cm(2). We illustrate these findings with experimental results of a 1,968-junction array having J(c) = 10 kA/cm(2) that was found to couple 0.1 - 0.8 mW to a 56-Ohm load in the range 100-300 GHz.

Recently, as an increasing number of fisheries have begun to experience severe declines there has been increased interest in how social scientists might help to address some of these problems. In managing fisheries, it is humans who must be understood and managed. Furthermore, some managers have begun to question the view of biological conservation as the primary goal of management, seeing economic and social goals as equally important. Social science studies of fisheries indicate that not all members of a given user group operate in the same way, or have the same impact on marine ecosystems. People's behavior is often influenced by family, community, and other sociocultural variables in addition to economic and ecological considerations. Using the perspectives and methodologies derived from disciplines such as anthropology and sociology, fisheries managers should be able to develop policies which integrate and balance economic, social and biological objectives. Management systems which are more compatible with broad user group values should result in higher compliance and reduced enforcement costs. An overview of recent social science research pertaining to fisheries management is discussed, and examples presented on the relevance of social science information in crafting successful management regimes.

THE ISOTHERMAL APPROXIMATION - APPLICATION OF VARIOUS ATOMIC DATA SO ASTRONOMY & ASTROPHYSICS LA English DT Article DE SUN, X-RAYS; ATOMIC DATA ID EMISSION; FLARES AB The most temporally complete set of solar soft Xray flux measurements available at the present time is contained in the archive record of 0.5 - 4 Angstrom and 1 - 8 Angstrom broad-band ion chamber observations from the Geostationary Operational Environmental Satellite (GOES) spacecraft. The archive contains a nearly continuous record of the soft X-ray observations since 1974. Physical analyses of these measurements are often carried out under the isothermal plasma approximation. In this paper we present calculations of the ion chamber current ratio temperature relationship for soft X-ray detectors onboard four GOES satellites whose data comprise the main historical X-ray record. The present calculations update and extend results obtained by Thomas et al. (1985) for the GOES-I detectors. Our analysis has been performed using two modern sets of theoretical X-ray spectra calculated by Mewe et al. (1985, 1986) and by Raymond (Garcia 1993). Comparisons of the detector responses obtained for each of the above theoretical spectra are performed. These analyses indicate that both Mewe et al. and Raymond X-ray spectra provide mutually consistent interpretations of measured GOES X-ray data. Deficiencies in the physical interpretation of a mixture of low-temperature (active region) and high-temperature (flare) plasmas resulting from the isothermal approximation are pointed out and discussed. It is shown that the so called flare ''thermodynamic measure'', defined here and derived from GOES measurements, compares well with co-temporal values obtained from the analysis of the Yohkoh BCS spectra. It is proposed that the presented method of a thermodynamic measure analysis may be useful in the interpretation of global flare thermodynamics. C1 NOAA, SPACE ENVIRONM LAB, BOULDER, CO 80303 USA.

The rapidly rotating star is not known to possess a spectroscopic companion that may be held responsible for the observed emissions. Interpreting the X-ray modulation as rotational modulation and combining the value of the rotation period with the optically determined vsini, the stellar radius is found to be consistent with the photometrically determined radius. This may be the first non-interacting, early F V star discovered as a strong, nonthermal radio source. From kinematic arguments, 47 Cas is a likely member of the Pleiades Moving Group, and may thus be very young. C1 UNIV COLORADO, JOINT INST LAB ASTROPHYS, BOULDER, CO 80309 USA.

Specifically, in both sources we have resolved the F = 6-5, 5-4, and 4-3 hyperfine transitions of the J = 5-4 fine-structure levels and detected the blended hyperfine structure of the J = 4-3 fine structure levels. At the J = 3-2 fine-structure levels, we have observed new transitions of NS, a known interstellar molecule, which severely contaminates the search for CH2 hyperfine transitions. These new sensitive observations finally confirm the existence of interstellar CH2 which was tentatively reported by us some years ago. C1 NATL READIO ASTRON OBSERV,TUCSON,AZ 85721.

In particular, we determine to what extent temperatures can be constrained and the corresponding uncertainties in the luminosities and emission measures lowered by fitting simultaneously count rates from the Einstein imaging proportional counter (IPC), the ROSAT Position Sensitive Proportional Counter, the ROSAT Wide Field Camera (WFC) (both filters), and the EXOSAT Low Energy Telescope with the 3-Lex filter. We use published plasma emissivities with solar photospheric abundances. Since it has been found that single-temperature plasmas do not fit IPC data well, we assume a two-temperature plasma model. We find that, even with count rates from all of the above filters and overly optimistic error estimates, it is still not possible to determine a unique two-temperature solution. However, since the use of count rates from many filters can reduce substantially the number of possible solutions, temperature solutions determined by other means can be tested. We carry out such an analysis on a set of 18 nearby late-type stars to determine possible two-temperature solutions using multifilter photometry, and we compare these results with the temperature solutions derived by Schmitt et al. (1990) using IPC spectral data. In general, the two-temperature fits derived from the IPC spectral data are inconsistent with our results, with our data implying that, for many stars, the two temperatures derived by the IPC may be too low by about a factor of 2. The EXOSAT transmission grating Spectrometer (TGS) spectra of Capella and sigma2 CrB support this conclusion. For Procyon and 70 Oph, though, the presence of a temperature component cooler than a million degrees (not detected by the IPC) is deduced. While our analysis suggests the existence of more than one temperature in the coronae of late-type stars, in many instances our WFC data appear to be inconsistent with the presence of significant emission measure over a broad temperature distribution. This, together with the success of two-temperature plasmas in fitting IPC and TGS data, implies that for many stars, the coronal emission measure distribution may in fact be dominated by two distinct temperature regimes.

The white dwarf accounts for over 90% of the observed extreme ultraviolet flux detected from this system. Analysis of ROSAT Wide Field Camera and IUE data both suggest a white dwarf temperature of approximately 28,700 K. Optical photometry and the IUE LWP spectrum (with the white dwarf contribution removed) imply that the late-type star has a spectral type of K1-3 V, and a distance of 55 +/- 5 pc. Using this distance, the observed IUE SWP flux, and the best-fit temperature results in a white dwarf radius of 0.0088 R.. The estimated white dwarf mass is then approximately 0.91 M.; somewhat over-massive compared to field white dwarfs. Optical photometry of the K star reveals a ''spot'' modulation period of approximately 10 hr (now observed over 3 yr). However, radial velocity observations have revealed no significant variations. Spectroscopic observations place a low limit on the lithium abundance, but do show rapid rotation with a upsilon sin i of 90 +/- 10 km s-1. The K star was detected as a radio source at 3.6 cm (on two occasions) and 6 cm by the Very Large Array. The most likely evolutionary scenario is that the K star and hot white dwarf form either a wide binary or common proper motion pair with an age of 0.1-0.2 Gyr-consistent with the evolutionary timescale of the white dwarf and the rapid rotation of the K star. However, from the proper motion of the K star, this system does not seem to be associated with any of the known young stellar groups.

Comparison of the RADM results with surface measurements of hourly ozone concentrations from the National Dry Deposition Network (NDDN) sites showed distinct diurnal variations in the model high bias. Here, we investigate what part of this phenomenon is influenced by the coarse vertical resolution of RADM in representing the deposition layer. For certain deposition species in the model, we apply the planetary boundary layer (PBL) similarity theory to predict the high bias of the model results (volume averages) to the surface observations (time series at a point) for the horizontally homogeneous case. Here, we applied the profile corrections to a secondary species O-3, which is one of active reacting species even at night especially with NO. However, we attempted to separate the effect of deposition layer thickness from the effects of other horizontal and vertical resolution such as emissions source distribution during the NO-O-3 titration process for a clearer presentation of our hypothesis. The study shows that there are situations when a considerable portion of the high bias of model O-3 concentrations at night is explained by the coarse vertical resolution in the deposition layer. It is shown that the model needs to resolve, at least, the lower half of the PBL in order to predict surface deposition fluxes correctly. Comparison with several NDDN observations shows that for certain NDDN sites the present hypothesis cannot fully explain the model's high bias of daily minimum O-3. In a companion paper, the effect of emission source distribution in representing the NO-O-3 titration process will be studied to investigate causes of the model bias further.

Fluxes were derived from the concentration gradients of total gaseous Hg between sampling heights of 25 and 165 cm and the concurrently determined turbulent diffusion coefficients of reference trace gases (i.e. H2O or CO2). The concentration and gradient data of Hg0 measured during the campaigns generally fell in relatively narrow ranges of 1.52-3.68 and -0.16 to 0.32 ng m-3 (over 140 cm), respectively: means (+/- 1 S.D.) for the corresponding emission and deposition fluxes were found to be 7.5 +/- 7.0 (n = 30) and -2.2 +/- 2.4 ng m-2 h-1 (n = 9), respectively. From the data collected during a series of sequential measurements, reproducible patterns of diurnal exchange emerged: (1) small bidirectional fluxes of Hg0 in the morning, (2) peak emissions near midafternoon, and (3) generally insignificant exchange during the nighttime. The fluxes of Hg over soil surfaces appear to be driven by a combined effect of several meteorological factors, including wind speed, vertical mixing, and soil temperature. Comparison of environmental conditions for both emission and deposition events showed that the direction of fluxes may be strongly influenced by the stability conditions of the boundary layer. The overall results of our emission and dry-deposition measurements in concern with recent studies of wet-deposition rates in the forest ecosystem suggest that source strengths of this forest soil system may be of the same order of magnitude as sink strengths.

Millimeter wave radar can be used to document small-scale spatial structure of cirrus and marine stratus clouds. Its data can be used to estimate profiles of ice content, particle size and concentration in cirrus clouds and profiles of liquid water content and turbulence in marine stratus clouds. New results with mm wave radar suggest that plate-like crystals may be distinguishable from aggregates with polarization techniques. Quantitative information about cirrus cloud ice crystal fallspeeds, and therefore ice mass flux, can also be produced with newly developed techniques that exploit the sensitivity and velocity precision of such radars. The good sensitivity to cloud particles, the immunity from ground clutter contamination, and the good spatial resolution of millimeter wavelength radar make it an excellent instrument for documenting quantitative microphysical and dynamical properties of non-precipitating and lightly precipitating clouds.

With specific examples from current technologies and a three-dimensional numerical model, this paper discusses the potential for accurately measuring and modeling the formation and fallout of mountain precipitation, a critical factor in the global climate system because it affects water resources. This paper describes application of the model and remote sensors to meet the goals of programs such as the Global Energy and Water Cycle Experiment (GEWEX). To accurately predict precipitation, general circulation models that have 100-km grid spacing require parameterization of the effects of subgrid-scale processes within cloud systems. The contribution of scales of atmospheric motion 10-20 km in forming precipitation and determining its distribution on mountain ranges is demonstrated.

Examined is the extent to which the observed height variation of F(m,z), the vertical wavenumber spectrum of velocity at height z and wavenumber m, can be explained by the observed source in the lower atmosphere. The near uniformity of F(m,z) around the globe at fixed z is attributed to saturation in combination with the ''global'' source (of gravity waves). To account for the origin of this source, a conjecture is made regarding two-dimensional turbulence cascade in the lower atmosphere and the relation of this cascade to the frequency spectrum of gravity waves observed in the middle atmosphere. Pointed out is the relation of observed ''smooth'' spectra to daily and hourly occurrences of quasi-monochromatic waves, as well as the possibility that middle atmospheric waves be viewed as a ''fossil'' turbulence (in our case and upward propagation from a region of active turbulence to a region of inactive turbulence). Experiments are suggested to determine quantitative aspects of the global (such as its coherence length along a meridian).

Weight changes due to the water sorption, effects of water sorption on mechanical properties, and fractographic observations were conducted. It was found that (i) the water sorption was diffusion-controlled, (ii) both break stress and modulus of elasticity reduced by increasing the amount of absorbed water, and (iii) fractographic observations showed that fracture pattern of the wet/dry/wet lamellar structure was not straight line, rather S-shaped pattern, suggesting that (a) mechanical properties (particularly, the modulus of elasticity) of the wet portion were not same as those in the dry portion, and (b) there could be an internal residual stress developed at/in the interfacial zone between the dry and wet portion. By one-layer removal from the wet/dry/wet lamellar structure composites, the residual stress was calculated from measuring the radius of the curvature. It was found that for all water-sorbed composite materials, tensile residual stresses were developed, which were from 30 to 40% of the break stresses for TPH, Charisma, and Durafil VS, and was 78% of the break stress for Z100 material.

However, the accuracy of the conventional type of mechanical bulge ductility testing unit is poor in determining the actual elongation. In this development, a photo-sensitive device is provided in the detecting portion to accurately measure the elongation. The sensitivity depends on the type of the materials tested. A Pyrex(R) glass ball is utilized as a punching ball to provide equally distributed light. Pushing of the Pyrex glass is activated by a hydraulic media to control the punching velocity. Accuracy and reproducibility were primarily checked with copper thin foil deposited on polyimide substrates. Two types of dental articulating papers (paper-based and plastic-based) were tested. It was suggested that an appropriate selection of articulating paper to mark the occlusal interferences is essential for precise determination of occlusal harmony.

The experimental technique is based on the phenomenon of DNA intercalation using fluorescence polarization for quantitative measurements. The assay architecture is analogous to a protocol presently used for competitive immunoassays, whereby an intercalating dye or fluorochrome would compete with or be displaced by the analyte (test compound). Our competitive binding assay utilizes DNA binding sites and a fluorescent intercalating dye. The carcinogenic analytes investigated were benzo[a]pyrene, dibenz[a,h]anthracene, dibenz[a,j]anthracene, benz[a]anthracene, benzo[j]fluoranthene, benzidine, aniline, parathion, pentachlorophenol and nitrobenzene. The noncarcinogenic hydrocarbons studied were naphthalene, anthracene, phenanthrene, benzo[k]fluoranthene and 1,2,3,4,5,6,7,8-octahydronaphthalene. The intercalating dyes examined were acridine orange, ethidium bromide, proflavin and 4,6-diamidino 2-phenylindale chloride (DAPI). Of the compounds studied, only the single ring compounds gave a negative response. All the other compounds investigated displaced the intercalated dye molecule. It has been determined that molecules require at least two adjacent benzene rings for intercalation to occur. The detection limits of this analytical method were between 10(-5) mol/L and 10(-8) mol/L for all materials tested.

Here, we present empirical equations for converting among measures of size for blue marlin, Makaira nigricans; white marlin, Tetrapturus albidus; and sailfish, Istiophorus platypterus, from the North Atlantic Ocean. A series of length-length equations allows conversion from any of six length measures to lower jaw-fork length; and a series of length-weight and weight-length equations allow conversion between lower jaw-fork length and round weight. To estimate the equations, we used large data sets that have recently become available. We incorporated bias corrections into the length-weight and weight-length equations and used robust regressions for the length conversions. Equations for each species are given by sex and also for combined sexes, so that conversions can be made whether the sex of the specimen is known or not.

Annual landings in numbers at age were estimated by application of separable virtual population analysis (VPA), which was used to estimate annual, age-specific fishing mortality for different levels of natural mortality (M = 0.2, 0.3, 0.4 and 0.5 yr(-1)). Mortality levels (F) ranged from 0.54 to 1.59 between 1979 and 1990 for fully recruited ages (4-7) (M = 0.3). Maximum spawning potential ranged from 42% to 50% based on mature female biomass, from 49% to 56% based on egg production, and from 22% to 30% based on total mature (male and female) biomass. Because black sea bass are protogynous hermaphrodites (transforming from females to males) and the effect of changes in population abundance on sex transformations is unknown, the percent reduction in males to females was estimated solely on increased mortality by fishing (ranging from 50% to 60% of the unfished proportion). Thus, the use of maximum spawning potential based on total mature biomass should also be considered for comparison to a biological reference point used in defining overfishing.

The wave, which reached a height of about 3 m above normal tide, injured 75 people and damaged property along Daytona Beach. Analyses of meteorological and oceanographic observations are consistent with the hypothesis that a squall line generated a long water wave.

BIOGRAPHICAL TRIBUTE WITH AN ASSESSMENT OF HIS CONTRIBUTIONS TO METEOROLOGY SO BULLETIN OF THE AMERICAN METEOROLOGICAL SOCIETY LA English DT Item About an Individual AB LeRoy Meisinger was a U.S. Weather Bureau meteorologist and aeronaut who worked vigorously to bring meteorology to the aid of aviation in the post-World War I period. He was killed at the age of 29 in a scientific ballooning accident that has been detailed in a companion paper by Lewis and Moore. Meisinger's personality and scientific profile are reconstructed by examination of his oeuvre, which contains research contributions augmented by popular articles in the magazines of the period. Meisinger's personal characteristics were those of a quiet, scholarly man with strong interests in science, music, and art. His experiences as a Signal Corps weather officer during World War I inclined him toward a career in meteorology. While stationed at the Fort Omaha Balloon School, he became intrigued with the possibilities of using the free balloon as a platform for tracking air currents. As a research meteorologist with the U.S. Weather Bureau after the war, Meisinger melded adventurous scientific ballooning with the more painstaking and arduous task of scrutinizing data from the limited upper-air network of kite stations. His principal research contribution was a form of differential analysis that extrapolated surface data to the 1- and 2-km levels by using climatological statistics from the upper-air network. The impressive line of research he pioneered at the bureau came to an immediate and abrupt end with his accidental death in 1924.

The development of correction algorithms for the in-orbit degradation of the visible and near-infrared channels, and for the nonlinearities of the thermal infrared channels of the Advanced Very High Resolution Radiometer(AVHRR) is;described. The impact of instrument performance on the accuracy of total ozone retrievals from measurements made with the Solar Backscatter Ultraviolet Spectral Radiometer:MOD 2(SBUV/2) is briefly discussed.

A prototype global land monitoring system was developed based on monthly maps of standardized anomalies of satellite derived Normalized Difference Vegetation Index, NDVI, and Channel 4 brightness temperature, T-4. Processing included post-launch updated calibration and cloud screening, fitting in the cloud induced gaps by monthly averaging acid interpolation, and suppressing residual noise by smoothing. Monthly maps were used to derive climatology, in terms of multiannual means and variability, and monthly standardized anomalies, which allow monitoring such extreme natural events as droughts and floods. However, some discontinuity and residual trends, which can still be traced in time series, preclude accurate detection of moderate ecosystem changes. Discontinuity results from the switch from NOAA-9 to NOAA-11 in 1988, and Mt. Pinatubo eruption in 1991. Residual trends can be attributed to a combined effect of satellite orbit drift and possible persistent error in calibration of solar channels. The satellite drift affects the solar and thermal IR channels through systematic variation of illumination geometry and diurnal heating/cooling of the surface and atmosphere, respectively. Examples are given to illustrate the magnitude of these effects. C1 RES & DATA SYST CORP,GREENBELT,MD.

These results allowed us to estimate the aggregate clearance rates of Lampsilis and total unionids in the lake. Retention efficiency for seston in the 0.79-1.00 mu m ESD size category was 0.44 whereas 0.07 was the corresponding value for 0.91-mu m microspheres in laboratory prepared mixtures of microspheres and cultured algae; respective values for the 0.63-0.79 mu m size category were not significantly different from zero. Particle shape may explain the difference between natural seston and microspheres. Particles in the picoplankton size range (<3 mu m ESD) were probably an important food resource to the mussels, since 35-49% of the seston volume in Lake St. Clair was smaller than 3 mu m ESD. Regression analyses of filtration rate as a function of temperature and food concentration showed that feeding rate was temperature driven and not saturated by available seston concentration. Lampsilis and total community clearance rates were maximum in September, with respective fractions of the water columns swept clear of 0.018 and 0.053 . d(-1).

Simulation of length-weight regressions showed that for sample sizes commonly encountered in fisheries research, estimates of the intercept are biased high. In contrast with this, estimates of mean weight-at-length are biased low. As a result, different bias-correction factors are necessary to adjust for transformation bias. When the objective is to estimate the intercept of the length-weight equation, two existing methods correct for transformation bias. The appropriate bias-correction factor for mean weight-at-length, however, is exp(sigma(2)/2) where sigma(2) is the residual variance of the regression. As an alternative to the log-transformation method, the properties of nonlinear least-squares regression were explored. Estimates obtained with nonlinear regression are less efficient, but are relatively robust to departures from the assumed error structure. Simulation of several sampling designs showed that greater precision without loss of accuracy is obtained as subsampling is concentrated toward the extremes of the length distribution.

The Ni(100) surface shows appreciably higher hydrogenolysis activity towards adsorbed aniline than the Ni(111) surface. Hydrogenolysis of aniline on the Ni(100) surface results in benzene formation at 470 K, both in reactive hydrogen atmospheres and in vacuum. External hydrogen significantly enhances the hydrogenolysis activity for aniline on the Ni(100) surface. Based on spectroscopic evidence, we believe that the dominant aniline hydrogenolysis reaction is preceded by partial hydrogenation of the aromatic ring of aniline in the presence of 0.001 Torr of external hydrogen on the (100) surface, In contrast, very little adsorbed aniline undergoes hydrogen induced C-N bond activation on the Ni(111)surface for hydrogen pressures as high as 10(-7) Torr below 500 K. Thermal dehydrogenation of aniline dominates with increasing temperature on the Ni(111) surface, resulting in the formation of a previously observed polymeric layer which is stable up to 820 K. Aniline is adsorbed at a smaller angle relative to the Ni(111) surface than the Ni(100) surface at temperatures below the hydrogenolysis temperature. We believe that the proximity and strong pi-interaction between the aromatic ring of the aniline and the surface is one major factor which controls the competition between dehydrogenation and hydrogen addition, In this case the result is a substantial enhancement of aniline dehydrogenation relative to hydrogenation on the Ni(111) surface.

Detailed studies of CF32+ show that the dissociation occurs by single-photon absorption which promotes the molecule to unbound excited states. Excitation thresholds for the photoinduced neutral-loss and charge separation reactions of SF2+ and SF32+ are apparent from the data. A qualitative interpretation of the competition between the neutral loss and charge separation processes is discussed in terms of a simple model of the potential energy surfaces.

Concentrations of organic carbon decrease dramatically in the upper part of the water column as organic matter is remineralized. Remineralization changes the character of organic matter associated with particles as they settle, and different pyrolysate distributions are consequently obtained. Nitrogen-containing compounds are more abundant in trap contents from the epilimnion and metalimnion, whereas saccharides and humic acids are more abundant in particles settling within the near-bottom nepheloid layer. Comparison of extractable n-alkane distributions to the pyrolysates of bulk organic matter indicates preferential degradation of algal components during sinking of sediment particles.

In either case, the negative logarithms of the doses required to achieve some particular effect (e.g., PED(50)) have generally been used as response variables. In pesticide development, these must ultimately be obtained from tests on intact organisms. Unfortunately, such parametric point-estimates derived from in vivo titration curves may unnecessarily limit the quality of the QSAR obtained. We show here that Scaled Rank Sums (SRS) represent an alternative, non-parametric approach which can provide robust quantitation of pesticidal efficacy suitable for either substituentwise regression analysis or CoMFA.

The distinctive orange-billed form of the Masked Booby (S. dactylatra granti), which is apparently endemic to the eastern Pacific Ocean, is by far the island's most abundant breeding seabird. Using aerial photography we obtained an accurate population estimate of 24,034 individuals, making this the second largest Masked Booby colony in the world. The only other species definitely known to breed at Malpelo is Swallow-tailed Gull (Creagrus furcatus), with an estimated 50 pairs. Other species that regularly occur at Malpelo and probably breed in small numbers include: Red-billed Tropicbird (Phaethon aethereus), Red-footed Booby (Sula sula), Black Noddy (Anous minutus), Brown Noddy (A. stolidus), and White Tern (Gygis alba). Great and Magnificent Frigatebirds (Frigata minor and F. magnificens, respectively) are present year-round and may also breed. Malpelo was uninhabited until 1986 when a small military garrison was established, which raises concern about the possibility of introduced pests.

The mass spectra of soot precursor particles from the lower flame display many peaks in the 200-300-amu range that are characteristic of polycyclic aromatic hydrocarbons (PAHs). The most prominent of these are the masses 252, 276, and 300, which correspond to the isomers of C20H12, C22H12, and C24H12, respectively. These masses are among those predicted by Stein and Fahr to be the most thermodynamically stable (''stabilomers'') under typical hydrocarbon flame conditions, and they have been previously reported as components of soot collected from a variety of fuels and combustion configurations. Carbonaceous soot from the upper region of the flame yields mass spectra composed of carbon-hydrogen clusters, CxHy with x = 3 to 24 and y usually 0, 1 or 2. Smaller amounts of PAH-like species with masses in the 418 to 444 amu range are also found. These results suggest that the carbonization process observed in this flame is the dehydrogenation of the PAH species formed in the lower flame unaccompanied by polymeric growth. The LMMS technique provides a lower bound value of the hydrogen mole fraction X(H) of 0.36 (C/H = 1.8) for precursor particles from the lower diffusion flame and 0.15 (C/H = 5.6) for carbonaceous soot aggregates.

The numerically predicted burning rates for the full mechanism describing a near-stoichiometric: burner-stabilized flame at a pressure of 25 torr, and final temperature of 2000 K are compared with the results using the reduced mechanisms, and the sources of inaccuracies are identified. The two reactions NO2 + H --> NO + OH and H-2 + OH reversible arrow H2O + H account for about 97% of the NO2 and H-2 consumption and NO and H2O production, and are the principal reactions involving OH and H atoms. The reactions 2OH reversible arrow H2O + O and NO2 + O --> NO + O-2 are important for OH and O, while the reactions NO2 + M --> NO + O + M and NO2 + H-2 --> HONO + H serve as important initiation reactions. The reactions O-2 + H reversible arrow OH + O, H-2 + O reversible arrow OH + H, and 2NO(2) --> 2 NO + O-2 are significant but of lesser importance. In reducing the mechanism, the steady-state assumptions for the intermediates O, H, and OH are shown to be good; however, their use is limited because the H and OH balance relations are dominated by the same reactions. As a result of these limitations, an asymptotic description of the flame structure using a one-step approximation to the kinetics is only able to predict the burning rate within a factor of three of the numerical result using the full mechanism.

It may be possible to produce maximally correlated ''EPR'' states of N electrodynamically trapped ions by entangling the collective motion state of the ions with the internal (spin) states of the ions. As steps toward this goal, we report the cooling of a trapped ion to the zero-point energy, and the realization of a coherent exchange between an external vibrational energy level and the internal spin state of a trapped ion.

As a consequence of this, precise measurements of the absolute decay rate and two or more independent decay correlation coefficients can provide a sensitive test of the Standard Model. The past year has seen significant activity aimed at reducing the uncertainty on the neutron lifetime and the antineutrino-spin and electron-spin asymmetry coefficients. The experimental results and their theoretical implications are reviewed. RP Dewey, MS (reprint author), NATL INST STAND & TECHNOL,GAITHERSBURG,MD 20899, USA.

Discovery cruise 165B in May 1987, reveals the water mass structure and associated velocity field of the shelf and upper slope of the Benguela upwelling system. Continental shelf water upwelling within the Benguela Current is drawn from the 12 degrees C (about 200 m) level. The upwelling water is drawn from oxygen depleted, tropical South Atlantic thermocline water that is advected along the shelf floor by a southward flowing subsurface current. Lower thermocline and intermediate water from the tropical South Atlantic are also observed flowing southward over the continental slope. Tropical Atlantic water generally resides north of the Angola-Benguela Front at 16 degrees S. A narrow band of upwelled water is observed well seaward of the shelf, along the western edge of a large Agulhas eddy, indicating that Agulhas eddies play a role in stirring eastern boundary upwelled water into the ocean interior. These eddies also draw into the interior tropical Atlantic water found over the upper continental slope. The net transport between the 120 and 350 isobaths as measured by the ship-mounted ADCP, referenced to the sea floor, is 0.9 x 10(6) m(3) s(-1) to the south, with 1.6 x 10(6) m(3) s(-1) of southward Rowing tropical Atlantic water and 0.7 x 10(6) m(3) s(-1) of northward Bowing upwelled surface water. The tropical thermocline water mass advected to the south is not observed offshore within the northward flowing Benguela Current, in an unaltered state, thus the 0.9 x 10(6) m(3) s(-1) must feed shelf upwelling south of 27 degrees S, implying a net offshore flux of upwelled water between Luderitz (26 degrees) and Cape Columbine (33 degrees S).

The daily time series furnished by the buoy array brings out the conspicuous importance of remotely forced intraseasonal variability in the form of equatorial baroclinic Kelvin waves during the evolution of the 1991-1993 El Nino, Notable variations along 140 degrees W included a major weakening of the Equatorial Undercurrent in late 1991 to early 1992, and a reduction in intensity of monthly period tropical instability waves during the latter part of 1991 compared to previous non-El Nino years. The North Equatorial Countercurrent showed no major signal due to this El Nino, in contrast to earlier warm events. Although anomalies of the South Equatorial Current spanning the equator were in an eastward sense during the height of the event, the result of these changes was that near-surface flow across 140 degrees W between 5 degrees S and 5 degrees N was close to zero, so there was apparently no large eastward transport of surface water past 140 degrees W into the eastern equatorial Pacific. The relative phasing of anomalies of thermocline depth, equatorial undercurrent speed and SST during the warm event of 1991-1992 was somewhat similar to that seen during the 1986-1987 El Nino, although the earlier event was followed by a strong cold (La Nina) event whereas the recent one was not. Uniquely among modern El Nino events, after the 1991-1992 episode appeared to end with a reappearance of the equatorial cold tongue in mid-1999, a second SST warming in the eastern Pacific occurred in early 1993. The present data set is inadequate to fully diagnose the mechanisms of SST change at 140 degrees W, but time series of insolation, air-sea temperature difference and humidity show that local air-sea heat flux variations (either radiative or turbulent) were probably not the primary cause of the SST changes during the El Nino. Similarly, although horizontal advective mechanisms were important contributors to SST signals at certain times, these alone did not account for the major warming and cooling events. Instead, the largest SST variations of the 1991-1992 El Nino can be ascribed to upwelling variations, and a simple parameterization for this process is presented. The major warming and cooling events in the central/eastern equatorial pacific occurred nearly simultaneously over a wide longitudinal range, indicating that oceanic wave processes could not have been the sole source of the changes.

Surface water fCO(2) data indicate significant differences between the springtime El Nino conditions and the autumn post-El Nino conditions. The autumn fugacity (Delta fCO(2)) maxima were approximately 15-55 mu atm higher than in the spring. The lower surface Delta fCO(2) values in the spring data set were the result of: (i) advection of CO2-depleted water from the west at the equator near 170 degrees W; and (ii) reduced upwelling and lower Delta fCO(2) distributions as consequence of lighter zonal winds in the eastern Pacific from 140 degrees W to 110 degrees W. Assuming the springtime data are representative of the El Nino conditions and the autumn data are representative of the post-El Nino conditions, it is estimated that the net annual CO2 flux during the 1991-1992 ENSO period is 0.3 Gt C. Over 60% of this flux occurred during the 4-month period in the autumn when Delta fCO(2) values were close to normal. The net annual reduction of the ocean-atmosphere CO2 flux during the 1991-1992 El Nino is estimated to be on the order of 0.5-0.7 Gt C. C1 NOAA,ATLANTIC OCEANOG & METEOROL LAB,MIAMI,FL 33149.

The spring-time conditions were influenced by an El Nino that had disappeared before the fall cruises. This contributed to a large seasonal contrast in surface temperature, carbon and nutrient concentrations, and thermocline depth. Nitrate, total inorganic carbon, and fugacity of CO2 values were significantly lower in the spring, while sea surface temperatures south of the equator were higher. The seasonal change in surface water chemistry at the equator is due to changes in upwelling of nutrient and carbon enriched water. Oxygen and CO2 anomalies at the surface point to approximately a three-fold increase in upwelling of thermocline water in the fall compared to the spring. The large-scale spatial variations in the surface chemistry patterns remained unchanged between spring and fall. There was a westward decrease in surface-water carbon and nitrate concentrations and a strong north to south asymmetry with higher carbon and nitrate values south of the equator. This pattern is attributed to input of carbon and nutrients with the South Equatorial Current from the east. Using velocities obtained from surface drifters tracks, along with reasonable gas exchange estimates, and a ''Redfield analysis'' to account for export biological production, this westward decrease in carbon and nutrients can be quantitatively accounted for in the region from 0 to 3 degrees S and 110 degrees W to 140 degrees W in the spring. In the fall the calculated concentration decrease is greater than observed, which is attributed to input from local equatorial upwelling along the pathway of water transit.

Our data set indicates that spectrophotometric A(T) measurements (AT(spec)) are both precise (+/- 1.8 mu mol/kg) and accurate; the mean observed difference between A(Tspec) and A(T) obtained potentiometrically in this study (A(Tpot)) is 1 mu mol/kg. As only two of the three measured parameters are required to characterize the CO2-system in seawater, this analytical redundancy of our analyses (C-T, A(T), PH) afforded an opportunity to evaluate, in terms of thermodynamic consistency, a recent calibration of m-cresol purple, a pH indicator. Using various carbonic acid dissociation constants, measured parameters were combined in pairs (C-T-A(T), pH-C-T, and PH-A(T)) to calculate a third parameter for comparison with the shipboard measurements. Depending on the selected set of carbonic acid dissociation constants, the average offset between directly measured and predicted values of A(T) and C-T was as Small as +/- 1 mu mol/kg. The results of this study indicate that the present 25 degrees C mCP calibration, paired with the 25 degrees C combined dissociation constants of Hansson and Mehrbach, produces accurate predictions of A(T) and C-T. Extensive replication of the shipboard spectrophotometric measurements made it possible to examine directly the sensitivity of derived parameters to variations or errors in input A(T) and pH. In accord with earlier theoretical treatments of this question, the results presented demonstrate that pH is imprecisely predicted from A(T) and C-T, whereas imprecision in measured pH-at the level typical of spectrophotometric measurements (+/- 0.0004)-contributes negligibly (+/- 0.3 mu mol/kg) to imprecision in derived A(T) and C-T. In view of the high precision of pH(Tspec) measurements and both the precision and reliability of C-T measurements (supported by the use of certified SIO reference materials) PHTspec and C-Tcoul constitute a particularly useful pair of parameters for shipboard study of the oceanic carbon dioxide system. The results indicate, as well, that the A(T)-PHTspec pairing is of particular interest in ocean regions where simple A(T) VS salinity relationships are observed. In light of recent advances, the role of pH measurements in CO2-system characterizations should be re-evaluated. Spectrophotometric measurements of pH have much to contribute in documenting the oceans' evolving response to anthropogenic CO2. C1 NOAA,PACIFIC MARINE ENVIRONM LAB,SEATTLE,WA 98115.

Large volume water samples (similar to 1500 1) were filtered in situ to separate particulate (> 0.5 mu m) and dissolved Th isotopes and Am-241. Thorium-230 displays increases in both particulate and dissolved activities with depth, with dissolved Th-230 greater and particulate Th-230 lower in the deep central Nansen Basin than at the Barents Sea slope. Dissolved Th-228 activities also are greater relative to Ra-228, in the central basin. Residence times for Th relative to removal from solution onto particles are similar to 1 year in surface water, similar to 10 years in deep water adjacent to the Barents Sea slope, and similar to 20 years in the Eurasian Basin Deep Water. Lead-210 in the central basin deep water also has a residence time of similar to 20 years with respect to its removal from the water column. This texture of scavenging is reflected in distributions of the particle-reactive anthropogenic radionuclide Am-241, which shows higher activities relative to Pu in the central Nansen Basin than at the Barents Sea slope. Distributions of Cs-137 show more rapid mixing at the basin margins (Barents Sea slope in the south, Gakkel Ridge in the north) than in the basin interior. Cesium-137 is mixed throughout the water column adjacent to the Barents Sea slope and is present in low but detectable activities in the Eurasian Basin Deep Water in the central basin. At the time of sampling (1987) the surface water at all stations had been labeled with Cs-134 released in the 1986 accident at the Chernobyl nuclear power station. In the similar to 1 year since the introduction of Chernobyl Cs-134 to th, Nansen Basin, it had been mixed to depths of similar to 800 m at the Barents Sea Slope and to similar to 300 m in the central basin. ''Pre-Chernobyl'' inventories of Cs-137 (as well as Pu-239,Pu-240) are 10 times those expected from global atmospheric fallout from nuclear weapons testing and are derived principally from releases from the Sellafield, U.K., nuclear fuel reprocessing facility on the Irish Sea. Based on the sources of Cs-137 to the Nansen Basin, mixing time scales are 9-18 years for the upper water column (to 1500 m) and similar to 40 years for the deep water. These mixing time scales, combined with more rapid scavenging at the basin margin relative to the central basin, produce residence times of particle-reactive radionuclides in the Nansen Basin comparable to other open ocean areas (e.g. north-west Atlantic) despite the presence of permanent ice cover and long periods of low-light levels that limit productivity in the Arctic.

The film thicknesses ranged from 0.42 mu m to 1.9 mu m. The films were grown on silicon substrates. The optical measurements were carried out on windows formed by removal of the substrate from under the central portion of each film. Three spectra were measured for each of the diamond windows thus formed; the top surface reflectance, the bottom surface reflectance, and the transmittance. The specimens were also characterized by Raman spectroscopy. The transmittance and reflectance spectra were analyzed by fitting the data to a set of model functions that take into account scatter losses from the rough surfaces of the films, as well as specular reflection from the surfaces and internal absorption ill the films. This method should be useful for analyzing the transmittance and reflectance of thin films with moderately rough surfaces. The fitting procedure gave values for the refractive index and absorption coefficient as functions of photon energy (E), the film thickness, and the root-mean-squared roughnesses of the top and bottom surfaces, with the following results. The top surface of each film is rougher than the bottom surface. The refractive indices are similar to or slightly less than the refractive index of single-crystal diamond. The absorption spectra of the films, alpha(E), show distinct components at low and high photon energies (within the 0.5-6.5 eV range). The low-energy component of alpha(E) is fitted by the Tauc function, alpha(E) = alpha(1)(E-E(1))(2)/E for E > E(1), with values of the threshold energy E(1) between 0.9 eV and 2.1 eV. The high-energy component of alpha(E) consists of a rapid increase in absorption above 5.5 eV, which is the indirect band gap of-diamond. The magnitude of the high-energy component is significantly larger than that of alpha(E) for pure single-crystal diamond in the 5.5-6.5 eV range. The low-energy Tauc absorption is attributed to an amorphous carbon phase in the films, and the enhanced absorption (relative to single-crystal diamond) above 5.5 eV to structural disorder within the crystalline diamond phase. The Raman spectra also indicate the presence of amorphous carbon and structural disorder within the diamond phase. C1 NIST,DIV CERAM,GAITHERSBURG,MD 20899.

The model related total May through October rainfall to the absolute maximum of NDVI. This relationship was based on an idea that the amount of vegetation formed under optimal weather conditions can describe the climatic resources of an area. In Sudan it was found that there was a strong relationship between NDVI and seasonal rainfall (R = 0.95).

Using these data, two guideline values (an effects range-low and an effects range-median) were determined for nine trace metals, total PCBs, two pesticides, 13 polynuclear aromatic hydrocarbons (PAHs), and three classes of PAHs. The two values defined concentration ranges that were: (1) rarely, (2) occasionally, or (3) frequently associated with adverse effects. The values generally agreed within a factor of 3 or less with those developed with the same methods applied to other data and to those developed with other effects-based methods. The incidence of adverse effects was quantified within each of the three concentration ranges as the number of cases in which effects were observed divided by the total number of observations. The incidence of effects increased markedly with increasing concentrations of all of the individual PAHs, the three classes of PAHs, and most of the trace metals. Relatively poor relationships were observed between the incidence of effects and the concentrations of mercury, nickel, total PCB, total DDT and p,p'-DDE. Based upon this evaluation, the approach provided reliable guidelines for use in sediment quality assessments. This method is being used as a basis for developing National sediment quality guidelines for Canada and informal, sediment quality guidelines for Florida.

Almost all the elements except cadmium were highest in liver. Cadmium levels in kidney were higher than those in liver and muscle for all animals analyzed. Concentrations of mercury increased significantly with age in muscle, fiver and kidney, as did iron levels in muscle and liver and cadmium levels in muscle, while manganese concentrations decreased with age in muscle and kidney. The kidney also showed decreased copper concentration with age. Cadmium concentrations of the northern fur seals in this study were higher than the other otariids, reflecting a predominantly squid diet. Concentrations of manganese and mercury were found to be higher in the fur seals caught off Sanriku than in animals from the Pribilof islands, while those of zinc and;cadmium were found to be lower. Variable concentrations of cadmium might have been attributed to those in seawaters. Discriminant analysis of heavy metal concentrations was used to identify habitat. Sixty-three of 67 animals (94%) were correctly classified using this technique. Heavy-metal concentrations in tissues may provide a useful method to elucidate the primary feeding grounds of fur seals. C1 NATL MARINE MAMMAL LAB,SEATTLE,WA 98115.

We determined fluxes using relationships among the concentration gradients and fluxes of water vapor (measured with fast-response sensors and eddy correlation) and measured gradients in Hg-0 (sampled with a multi-replicate, high-precision device). The contaminated soils consistently exhibited significant emission of Hg-0 to the atmosphere. Fluxes associated with winds from the primary source area ranged from similar to 10 to similar to 200 ng m(-2) h(-1), up to several orders of magnitude above background. Fluxes increased exponentially with soil temperature, yielding a temperature coefficient similar to nitrogen oxide (exp[(0.065 +/- 0.011)T-soil], for T-soil = 7-29 degrees C). These results provided confidence in the method for Hg-0 because the gradients and fluxes behaved predictably. Fluxes appear to be controlled by volatilization of existing contaminant elemental Hg plus reduction of Hg2+ to Hg-0 in soil solution. We modeled the emission from an area of contaminated soils within similar to 20-50 m of our site using the flux/soil temperature relationship and annual temperature data. The predicted hourly fluxes were within 30-40% of our measurements and scaled up to an annual Hg emission rate of similar to 800 mu g m(-2) y(-1) We estimate the magnitude of the Hg-0 emission from the 100-ha contaminated area to be on the order of 1-10 kg/y.

This innovative system provides a framework so that users follow consistent methodologies for modeling various release scenarios. This is achieved through the use of a graphical interface that includes a query methodology enabling the program to identify the release scenario and ask appropriate questions for more details. In this paper we describe the design, implementation, capabilities and use of the Expert Interface for Superfund applications. The Expert Interface program is written in Microsoft Visual C++ for the Windows environment. For illustration purposes, this phase of the development considers two source categories. The generic source category consists of a point source, while the Superfund category includes a lagoon source. For each source type the program queries the relevant variables from the user. In addition, the Expert Interface asks questions regarding control options, receptors, meteorology and output formats. The Expert Interface then creates the input file required by the ISC dispersion model. Finally, the Expert Interface enables the user to run the ISC model and browse the results file.

Juvenile fish were used to minimize effects of reproductive status and migration. CYP1A was determined by two catalytic assays [aryl hydrocarbon hydroxylase (AHH) and ethoxyresorufin O-deethylase (EROD)I and by an immunoassay (ELISA) utilizing polyclonal antibodies raised against purified CYP1A from cod. AHH activities were measured by a standard method (AHH(std)) and by two variations of the standard method. All three primary CYP1A measures (AHH(std), EROD, and ELISA) showed consistent between-site differences, indicating that induction of CYP1A can be a reliable biomarker of contaminant exposure in fish if appropriate biological variables are controlled for in field studies. Multiple ANOVA demonstrated that the AHH(std) and ELISA data showed less variability due to species or temporal differences, and less unexplained variability, compared to the data from the EROD assay or either variation of the AHH assay. For all measures, variability associated with site differences far outweighed species or temporal variability. Immunoassay, while less sensitive than the AHH(std) assay, is nonetheless recommended to be used in conjunction with catalytic assays because of the potential for samples to lose catalytic activity if not handled properly. The current results suggest that the lower noncontaminant-related variability of AHH(std) makes this CYP1A measure potentially more useful for monitoring programs in which analysis of trends is a primary goal.

Experimental evidence for the formation of the DMS . OH and CH3SOx . O-2 adducts are described and used in a simple 'box model' to calculate the ratio of [MSA]/[SO42-] observed in the atmosphere. These calculated ratios are compared with those inferred from field measurements. Based on these comparisons, we suggest that the changes with temperature in the mechanism of the OH + DMS reaction, one of the primary initiation steps in atmospheric DMS oxidation, are unlikely to be the source of the variation in the [MSA]/[SO22-] ratio with temperature. We suggest that the competition between the thermal decomposition of adducts such as CH3SO2 and their bimolecular reactions with atmospheric species is the likely cause of the variation. Finally, a few observations needed to better our understanding of the DMS oxidation are identified. C1 NOAA, ENVIRONM RES LAB, AERONOMY LAB, BOULDER, CO 80303 USA.

The fractional abundance of HCl shows a threshold behaviour as a function of temperature history; on a 10 day timescale, the abundance dropped sharply in those air parcels experiencing a temperature < 195 K, but little or no change was seen in parcels which stayed warmer than this temperature. The behaviour mirrors well the temperature behaviour calculated for the transformation of HCl into reactive forms (Cl-2, HOCl) from laboratory studies of sulfate aerosols and polar stratospheric clouds. During the course of the winter, the fractional abundance of HCl outside the vortex decreased from its values in late May by about a third, while inside it dropped to near zero by early August. Some recovery was evident in October. Examples of the peel-off of low-HCl air equatorward of the wind maximum were evident in early June. Meteorological trajectories are used to show, in a case study of a flight in early August, that air parcels which experienced temperatures of < 195 K, and as a result had low fractional HCl abundances, did so largely poleward of the maximum in the polar night jet stream. Encountering temperatures of < 195 K during the previous 10 days was a necessary and sufficient condition for the transformation of HCl into reactive forms by heterogeneous reactions. The trajectories further showed that air arriving from sub-tropical latitudes had higher fractional HCl abundances than the air in the middle latitudes, and much higher fractions than the air at high latitudes. The resulting picture is one in which the fractional abundance of HCl in air at mid latitudes was the result of mixing of air from sub-tropical latitudes with air mainly from polward of the jet stream core which has experienced temperatures < 195 K. The sensitivity of the fractional abundance of HCl to the assumption that no HCl enters the stratosphere via the tropical tropopause is examined in the light of an observed profile near the equator with a volume fraction of 0.4 ppb HCl, zero ClO and tropospheric mixing ratios of CFCs at the tropical tropopause.

The content of triarylphosphine oxide comonomer in the melt synthesized copolymers was controlled from 0-30 mole%. The copolymers were crystallizable at 10 and 20 mole% incorporation of the phosphine oxide comonomer and produced tough solvent resistant films. The crystallinity was totally disrupted at 30 mole%, but the Tg values systematically increased from 58 degrees C to 89 degrees C. Dynamic TGA results in air at 10 degrees C/minute showed that the char yield increased with phosphine oxide content. Cone calorimetric tests in a constant heat environment (40 kW/m(2)) were employed to investigate the fundamental flame retardancy behavior of the copolymers. Significantly depressed heat release rates were observed for the copolymers containing phosphine oxide, although carbon monoxide values appeared to increase. ESCA studies of the char show that the phosphorus surface concentration was significantly increased relative to copolymer composition. It was concluded that the triaryl phosphine oxide containing nylon 6,6 copolymers had improved flame resistance and that tough melt processible films and fibers could be produced from these modified copolyamides.

The glass transition temperature increased from about 150 degrees C for the control bisphenol-a polycarbonate system to 186 degrees C for the 50 wt. percent copolymer. The char yield via dynamic TGA in air increased from 0% for the control to 30% at 700 degrees C for the 50% copolymer. The homopolymer had a Tg of 202 degrees C, but only low molecular weight was achieved. In contrast, tough, transparent, high Tg polyarylates were prepared with terephthaloyl chloride that had a high char yield in air. Transparency and toughness were maintained in the copolymers, and the char yield in air increased significantly with phosphorus concentration. The materials are being characterized as improved fire resistant transparent systems and initial cone calorimetry studies do show that the heat release rate is significantly decreased.

In addition to evidence of the well known chain-stripping elimination of H2O and the chain-scission reactions, which occur during the pyrolysis of pure PVA, evidence is presented in support of cyclization and radical reaction pathways responsible for the conversion of unsaturated carbons into aliphatic carbons. Two general mechanisms; one described as a physical encapsulation, and the other a lowering of the average volatility of certain degradation products, are proposed for the primary modes of action of maleimides on the pyrolysis of PVA.

This methodology consists of burning materials using a bench-scale method that simulates realistic fire conditions, measuring the concentrations of the following primary fire gases - CO, CO2, O-2, HCN, HCl, HBr, and NO2 - and predicting the toxicity of the smoke using an empirical mathematical model called the N-Gas Model. The model currently in use is based on toxicological studies of the first six of the above listed primary gases both as individual gases and complex mixtures. The predicted toxic potency (based on this N-Gas Model) is checked with a small number of animal (Fischer 344 male rats) tests to assure that an unanticipated toxic gas was not generated. The results indicate whether the smoke from a material or product is extremely toxic (based on mass consumed at the predicted toxic level) or unusually toxic (based on the gases deemed responsible). The predictions based on bench-scale laboratory tests have been verified with full-scale room burns of a limited number of materials of widely differing characteristics chosen to challenge the system. The advantages of this approach are: 1. The number of test animals is minimized by predicting the toxic potency from the chemical analysis of the smoke and only using a few animals to check the prediction; 2. Smoke may be produced under conditions that simulate the fire scenario of concern; 3. Fewer tests are needed, thereby reducing the overall cost of the testing; and 4. Information is obtained on both the toxic potency of the smoke and the responsible gases. These results have been used in computations of fire hazard, and this methodology is now part of a draft international standard that is currently being voted on by the member countries of the International Standards Organization (ISO), Technical Committee 92 (TC92). In this chapter, a new 7-Gas Model including NO, and the data used in its development are presented. RP LEVIN, BC (reprint author), NATL INST STAND & TECHNOL,GAITHERSBURG,MD 20899, USA.

Increased interactions are needed between systematists and fishery scientists so systematists can obtain the material they need to study, and systematic problems of importance to fishery scientists can be resolved. The current shortage of systematists in some taxonomic groups, such as many invertebrate taxa, requires cooperative efforts by systematists and fishery scientists to train more specialists. Existing fishery sampling programs can aid in monitoring and understanding biological diversity at relatively little additional cost by expanding collecting efforts to include more taxa. The resulting voucher material serves to document the presence of a given species in time and space, and these specimens can be used for baselines of such things as heavy metals, pesticides, and parasite loads. Systematists need to translate their technical papers into practical guides and keys that can be used by fishery scientists in field situations.

Linetransect methods were used from a 53-m research vessel. Approximately 10,100 km were searched, and 515 groups of cetaceans were seen. The estimated abundances and coefficients of variation (in parentheses) of the most common small cetaceans are the following: 226,000 (0.28) short-beaked common dolphins, Delphinus delphis; 78,400 (0.35) Dall's porpoises, Phocoenoides dalli; 19,000 (0.41) striped dolphins, Stenella coeruleoalba; 12,300 (0.54) Pacific white-sided dolphins, Lagenorhynchus obliquidens; 9,470 (0.68) longbeaked common dolphins, Delphinus capensis; and 9,340 (0.57) northern right whale dolphins, Lissodelphis borealis. The estimated abundances (and CV's) of the most common large cetaceans are 2,250 (0.38) blue whales, Balaenoptera musculus; 935 (0.63) fin whales, Balaenoptera physalus; 756 (0.49) sperm whales, Physeter macrocephalus; and 626 (0.41) humpback whales, Megaptera novaeangliae.

The two surveys were designed to provide a combined estimate of cetacean abundance for winter and spring (cold-water) conditions; they complemented a summer and fall ship survey in 1991. The study area (264,270 km2) extended about 278 km (150 nmi) off the coast of southern California, and 185 km (100 nmi) off the coast of central and northern California. A primary team of two observers searched for cetacean species through bubble windows that allowed an unobstructed view to the sides and directly beneath the aircraft. A third, conditionally independent observer searched through a belly window and reported animals that were missed by the primary team. Approximately 7,069 km and 5,973 km were searched in 1991 and 1992, respectively, resulting in 253 sightings of at least 18 cetacean species (some animals could only be identified to higher taxa). Estimates of abundance and coefficients of variation (in parentheses) for the most common small cetaceans are the following: 306,000 (0.34) common dolphins, Delphinus spp.; 122,000 (0.47) Pacific whitesided dolphins, Lagenorhynchus obliquidens; 32,400 (0.46) Risso's dolphins, Grampus griseus; and 21,300 (0.43) northern right whale dolphins, Lissodelphis borealis. Abundance estimates (and CV's) for the most common whales are the following: 892 (0.99) sperm whales, Physeter macrocephalus; 392 (0.41) beaked whales, genera Mesoplodon and Ziphius; 319 (0.41) humpback whales, Megaptera novaeangliae; and 73 (0.62) minke whales, Balaenoptera acutorostrata.

Effects of low air temperature during the winter fishery on juvenile and female adult crabs and on the developing eggs brooded by the females were simulated in the laboratory by exposing crabs to cold air (-20 to +5-degrees-C) up to 32 minutes; controls were not exposed. Exposure was expressed as degree.hours (degrees-h), the product of temperature (degrees-C) and time (hours). Severe exposure caused death: median lethal exposure stabilized at -3.3 +/- 0.8-degrees-h for juveniles and -4.3 +/- 0.5-degrees-h for adults after 16 days. Exposure also reduced vigor (measured by righting ability), caused pereiopod autotomy, and depressed adult feeding rates and juvenile growth. Exposures causing one-half the crabs to cease righting were -1.2 +/- 0.3-degrees-h for juveniles and -2.1 +/- 0.3-degrees-h for adults (measured immediately after exposure). Mean pereiopod autotomy ranged up to 44% for juveniles exposed to -2-degrees-h, and up to 10% for adults exposed to -10.6-degrees-h. Ecdysis of juveniles was not affected, but exposed juveniles frequently shed additional pereiopods with the molt. Prompt return of incidentally caught Tanner crabs to the sea when temperatures are below freezing should reduce adverse effects of cold aerial exposure.

Objectives of the 1992 cruise were to assess the precision, accuracy, and efficiency of a video camera system versus a traditional abundance index (longline catch per unit of effort [CPUE]) for juvenile pink snapper (''opakapaka''), Pristipomoides filamentosus, a commercially important eteline snapper in Hawaii. Precision of the video samples was reevaluated with data from 18 stations sampled during 1993 off Kaneohe Bay. The video index of the maximum number of opakapaka observed (MAXNO, the natural log-transformed mean of three camera drops) was best correlated with the log of longline CPUE (r=0.79, P<0.001, n=15). Variation in the data for video MAXNO was nominally less than that of the longline CPUE. No monotone trend over stations was noted in samples from 1993. Sample sizes of 33 stations for longline and 18 stations for video would be necessary to detect two-fold changes in abundance of opakapaka at a site, based on our analysis of the two end positions of the 10 windward Oahu stations that had three quantitative deployments. Reanalysis of power with data from the 1993 cruise indicates that a sample size of approximately 22 stations (alpha2=0.05) or approximately 17 stations (alpha2=0.1) would be necessary to detect twofold changes.

Analysis of new specimens allows reconsideration of the systematic status of this species and a subsequent transfer to a monotypic new genus Homarinus. Far smaller than its northern relatives, with a maximum observed carapace length of 47 mm, the Cape lobster has first chelae adorned with a thick mat of plumose setae and less abundant setae on the carapace, tail fan, and abdominal pleura, whereas these setae are absent in Homarus. Relative length and shape of the carpus on pereopod 1, tooth pattern on cutting edges of first chelae, shape of the linguiform rostrum, large size of oviducal openings, and structure of male pleopods differ from corresponding features in Homarus. Comparative analysis of DNA from the mitochondrial 16s rRNA gene demonstrated considerable sequence divergence of the Cape lobster (9.7%) from its putative congeners. The magnitude of this estimate relative to that between the two North Atlantic species (1.3%) further suggests that taxonomic revision is warranted. C1 UNIV MAINE,CTR MARINE STUDIES,ORONO,ME 04469.

The von Bertalanffy growth function parameters from the vertebral analysis were considered more robust (L(infinity) = 373, K = 0.038, t0 = -6.28, male; L(infinity) = 349, K = 0.039, t0 = -7.04, female). Comparison of male and female growth curves generated from vertebral data indicate a statistically significant difference; however, these differences are due primarily to larger sizes attained by adult females. Estimates of age at maturity indicate that dusky sharks follow the typical carcharhinid pattern of slow growth and late age at maturity. The size at maturity is reported at 231 cm FL and 235 cm FL for males and females, respectively. These lengths correspond to approximately 19 years for males and 21 years for females. The oldest fish aged from vertebrae was a 33+ year-old female.

The data were analyzed to determine species composition, size distribution, seasonal occurrence, movements, morphometrics, and growth of 928 incidentally captured turtles. Loggerhead turtles, Caretta caretta, were the most frequently captured species (83% of total catch), while Kemp's ridley, Lepidochelys kempi, and green turtles, Chelonia mydas, were caught less frequently (12% and 4%, respectively). The loggerhead turtle population consisted of a seasonably variable aggregation of subadult and adult turtles. The Kemp's ridley and green turtle populations were composed of subadult turtles and were captured primarily during winter months. Kemp's ridley and loggerhead turtles appeared to exhibit a seasonal north-south migrational pattern along the Atlantic coast. Regression equations were developed for the morphometric relationships of each species. Average yearly growth rates and estimates for the von Bertalanffy growth interval equation were calculated for loggerhead and Kemp's ridley turtles. These results indicate that the coastal waters of the Cape Canaveral area provide an important developmental habitat for the three species of marine turtle.

The research area of flow-induced, structures in polymers has expanded with the advent of in-situ measuring techniques. Studies of this type are useful for probing fundamental issues such as chain deformation, shifts in phase behavior, and the formation of novel shear-induced structures. The applications addressed include the kinetics of morphology evolution and the relationship between ultimate properties and morphology.

The copolymer is composed of polystyrene-polybutadiene-polystyrene (23 wt% polystyrene-d(8)) with cylindrical morphology in the quiescent state. The order-disorder transition (ODT) was studied by in-situ SANS in a couette geometry as a function of temperature and shear rate. We observed that the ODT temperature shifted upward by 20 degrees C as the shear rate was increased from 0.1 to 25 s(-1). Sheared samples were also quenched and studied by transmission electron microscopy. A unique shear-induced morphology was found and tentatively identified as a transformation from the original p31m space group to a p3ml space group of lower symmetry, similar to a martensitic transformation in metals.

The time dependence of the peak maximum position, qm, and the intensity of the peak maximum, I(q(m)), were measured. The growth rate after cessation from the second shear rate was unaffected by the delay time. The mechanism for the coarsening parallel to flow was coupled to the extent of coarsening which occurred normal to the flow direction during the second shear rate.

The inter-rod distance of microfibrils under shear scales with C-(1/2) at high concentration, C. Orientational order parameters were calculated from the angular spread of the anisotropic SANS scattering peaks. Changes in the order parameter as a function of shear rate correlate to changes in the viscosity/shear rate profile. Particle alignment increases with increasing sheat rate, yet the highest degree of alignment for microfibrils (with axial ratios of similar to 45) was observed a short period after the cessation of shear flow. Relaxation occurred far more rapidly for shorter microfibrils with axial ratio of similar to 30. C1 MCGILL UNIV,PULP & PAPER RES CTR,DEPT CHEM,MONTREAL,PQ H3A 2A7,CANADA.

Oxidation of sulfide, as evidenced by the presence of zero-valent sulfur, occurs in this sulfidic sediment despite bottom water column and sediment anoxia. Thiosulfate shows a bimodal occurrence profile with a maximum in the late spring and fall, and is absent in midsummer. Two thiols, cysteine and glutathione, show maximal concentrations at 4 cm in mid-summer, which overlaps the highest gradient of sulfide and zero-valent sulfur occurrence patterns, suggesting a role in elemental sulfur redox or transport processes. Mercaptoacetate and mercaptopyruvate, were found in much lower concentrations and appear to be linked to the diagenesis of cysteine. Two mercaptopropanoic acids show temporal profiles increasing with sediment depth and may be linked to deeper sediment methanogenic bacterial activities.

These agents are considered as possible replacements for CF3Br. Liquid fuels were burnt in the counterflowing configuration and liquid and gaseous fuels were burnt in the coflowing configuration. The oxidizer was a mixture of air and agent which was introduced into the dame at an initial temperature of 25 degrees C or at an initial temperature of 150 degrees C. The amount of various agents required in the oxidizing stream to extinguish the flame was measured. The relative effectiveness of these agents was evaluated in terms of their mole fraction and their mass fraction in the oxidizing stream at extinction and was compared with that of CF3Br and N-2. The results show that CF3Br is the most effective agent in quenching flames followed by CF3I among the gaseous agents tested. On a mass basis the effectiveness of all other gaseous agents tested was nearly the same as that of N-2. C1 NIST,FIRE SCI DIV,BLDG & FIRE RES LAB,GAITHERSBURG,MD 20899.

At these higher concentrations the by-products of the inhibited flames may include correspondingly higher portions of corrosive gases, including HF and HCl. To examine the chemical and transport-related mechanisms important in producing these acid gases, a series of inhibited flame tests are performed with several types of laboratory-scale burners, varying agent type and concentration. A wet-chemistry analysis of the final products of the flames using ion-selective electrodes for F- and Cl- provides an experimental basis for quantitative understanding of the HF and HCl production. Production rates are measured for co-flow laminar and jet diffusion flames. Systematic selection of the agent concentrations, burner type, and air flow rates allows an assessment of the relative importance of agent transport and chemical kinetics on the acid gas production rates. These experimental results are then compared to a model which estimates the maximum HF and HCl production rates based on stoichiometric reaction to the most stable products. The results demonstrate the relative significance of F, Cl, and H in the inhibitor and fuel, as well as the effect of different burner configurations.

The chemistry of these agents is expected to be similar to that of agents which may be used as replacements for CF3Br. The burning rates of premixed methane-air flames stabilized on a Mache-Hebra nozzle burner are determined using the total area method from a schlieren image of the flame. The three inhibitors are tested over an initial mole fraction from 0 to 8% at nominal values of the fuel-air equivalence ratio, phi, equal to 0.9, 1.0, and 1.1. The measured burning rate reductions are compared with those predicted by numerical solution of the mass, species, and energy conservation equations employing a detailed chemical kinetic mechanism recently developed at the National Institute of Standards and Technology (NIST). Even in this first test of the kinetic mechanism on inhibited hydrocarbon flames, the numerically predicted burning rates are in excellent agreement for CH2F2 and CF4 and within 35% for CF3H. The effects of inhibitor concentration on the decomposition pathway of the inhibitors and on the H, O, and OH radical production and consumption rates are discussed. The modified decomposition pathway and the reduced radical consumption explain the diminishing effectiveness of CF3H and CH2F2 at higher concentrations.

Dependence of ignition delay on temperature, additive concentration, pressure, and mixture composition was studied and wherever possible comparisons were made with experimental results. The decomposition of additives can promote as well as inhibit reaction. With large concentrations of additives the exothermic combustion reactions can be severely attenuated by the endothermicity of the decomposition reactions of the additive, leading in some cases to a temperature decrease. The significance of these observations in terms of mechanisms for name inhibition is discussed. C1 USA,RES LAB,AMSRL WT PC,ABERDEEN PROVING GROUND,MD 21005.

Emphasis is placed on identifying those species and reactions with uncertain thermochemical and rate data that impact decomposition pathways and flame chemistry. Existing fluorinated hydrocarbon thermochemical and kinetic date were utilized when available. These data were supplemented through application of empirical, QRRK/RRKM, and ab initio methods, since much of the data necessary to complete the reaction set does not exist or is uncertain. Plug flow simulations were used to refine the reaction set and premixed flame simulations were used to predict the effectiveness of added fluorocarbon agents on flame suppression. The mechanism briefly outlined here should be considered only a framework for future model development, rather than a finished product. Future refinements will require experimental validation by high temperature flow reactor, premixed flame, and diffusion flame measurements, as well as measurements of important, yet currently uncertain, rate constants.

The rationale for this interest is the decomposition of these compounds when they are used as flame suppressants and the inevitable breaking of the C-F bonds. Literature information regarding thermodynamics and kinetics related to the decomposition of halons are summarized. Some recent experiments from our laboratory using a single pulse shock tube are described. Combination with the earlier results leads to a general picture of the channels for conversion of carbon-bonded fluorine to HF as well as the factors controlling the stability of the C-F bonds in high temperature systems.

This information has been used to construct a chemical kinetic mechanism for the prediction of the behavior of fluorocarbons as flame suppressants. Bond-additivity corrected (BAC) Mollet-Plesset many-body perturbation theory (MP4) calculations have been performed to obtain a large body of thermochemical data on both closed-and-open shell fluorocarbon species. In addition, data on transition state structures for reactions have also been generated and rate constants based on RRKM analysis have been derived. Comparisons between theory and experiment for both thermochemistry and kinetics show excellent agreement. Calculated bond dissociation energies have been correlated to Mulliken charge distribution and have been used to understand bond energy trends in terms of electrostatic effects and molecular conformation.

The changes in discharge behavior are shown, with the help of a Monte-Carlo simulation, to be consistent with discharge induced increases in the surface conductivity of the epoxy. This 'ageing' effect is shown to be accelerated as the frequency of applied voltage is increased from 50 to 800 Hz. The implications of the results on accelerated ageing tests and definition of partial discharge 'signatures' for possible pattern recognition are discussed.

This paper reports the results of radio interference (RI) and transient field measurements at-two GIS in Ontario, Canada. For comparison with RI levels taken at the GIS, RT levels outside two hospitals in the Toronto area were also measured. The transient field study covers electromagnetic interference (EMI) levels generated during switching operations, and includes measurements inside and outside the GIS. Measurements show that RI levels from the GIS were either below background levels, or contributed little to the background. RI levels outside the GIS and the hospitals were similar. Peak transient field values up to 580 V/m were measured inside the station building, and dropped to background values of IO V/m at about 120 m from the station. The transient field (E) dropped off at a rate of 3/2 power with distance (d) from the air-insulated 115 kV bus, i.e. E proportional to d(-1.5). C1 PW INT INC,VANCOUVER,BC V5R 5H4,CANADA.

The technique is a flow-injection method performed with chromatographic equipment, a flame-ionization detector, and subcritical and supercritical fluids. Each analysis is performed under isobaric and isothermal conditions. The resulting detector signal indicates the phase state. Twelve to fifteen mixture critical points can be determined in about 1 - 1.5 days. The binary mixtures studied were CO2 combined with: acetone, acetonitrile, 1-butanol, chloroform, ethanol, hexane, methanol, octane, 1-octanol, 1-propanol, 2-propanol, tetrahydrofuran, and toluene. Mixture critical points were determined within 1 degrees C and 1 atm (0.1 MPa). The maximum deviation between mixture critical pressures for CO2-toluene and CO2-methanol determined by the peak-shape method and data reported from view-cell techniques was 3%.
