During the TROUGHS (Tropical Ridge Observations of Underwater Geochemical Hydrothermal Signals) expedition we collected hydrothermal plume particles along a 350 km section, extending from approximately 8 degrees 40'N to 11 degrees 50'N, of the EPR north and south of the Clipperton Transform Fault. Over the segment south of the Clipperton Transform Fault, the S/Fe ratio in the particles ranged from about 0.9 to 10, with the highest values immediately over the new vent field at the 9 degrees 45.52'N site. These enrichments exactly coincide with the elevated (super 3) He/heat and CH (sub 4) /Mn ratios in the plumes over the same vent field. The S-rich particles are primarily organic and may be related to the 'bacteria blizzard' associated with the eruption. In addition, very high Cu/Fe and Zn/Fe ratios were observed in the hydrothermal plumes south of the Clipperton Transform Fault. These high ratios are indicative of the predominance of high-temperature, H (sub 2) S-rich vents between 9 degrees 35'N and 9 degrees 50'N. In contrast, the samples from the segment north of Clipperton Transform Fault had S/Fe ratios which ranged from 0.04 to 0.82, typical of mature, Fe-rich hydrothermal plumes. These results suggest that the gas-rich vent fluids at the 9 degrees 45.52'N site produced the sulfur-enriched particles in the water column. Gas-rich plumes and sulfur-enriched plume particles were also observed underneath the 1986 Megaplume on the Juan de Fuca Ridge (JdFR), suggesting a similar mode of formation. North of the Clipperton Transform Fault, the hydrothermal particles are dominated by Fe-rich oxyhydroxide particles, characteristic of mature high-temperature vent fields. The plume maximum is centered at 11 degrees 08'N. The Fe oxyhydroxide particles scavenge Ca, Si, P, V, Cr and As from seawater. For P and V the mean element/Fe ratios in the EPR hydrothermal particles are intermediate between JdFR and TAG hydrothermal systems. For As the mean element/Fe ratios of all three systems are about the same. New evidence for Si scavenging by hydrothermal Fe oxyhydroxide particles indicates that this sink for dissolved Si in the oceans is small.

We find that steep subduction was well developed by 2.5 Ga, which coincides with a major change in sedimentary rare-earth element patterns. Over 50% of all oceanic crust subducted steeply by 2.0-1.6 Ga, the same interval over which the average thickness of continental plates declined rapidly. Because producing thick plates requires many episodes of flat subduction, our model can explain why there are no known thick plates <1.6 Ga.

Pinatubo eruption AN - 50185991; 1995-015034 AB - NOAA has been archiving weekly and monthly gridded analyses of "radiatively equivalent" aerosol optical thickness over oceans on magnetic tape since June 29, 1989. These analyses are derived from the Advanced Very High Resolution Radiometer (AVHRR) on board the NOAA-11 polar orbiting environmental satellite. The eruption of Mt. Pinatubo in June 1991 and the ensuing dispersal of aerosol particles in the stratosphere occurred after two complete years of observations with essentially "background" particle concentrations in the stratosphere. This fortunate timing means that computing the difference between the average of the first two years of tropospheric aerosols and the "Post-Pinatubo" period of tropospheric and stratospheric aerosols provides a means of observing the evolution of the stratospheric aerosol cloud. Time series of zonal averages of these difference fields are presented and analyzed. These analyses indicate that by the end of 1993, the stratospheric aerosol optical thickness declined from its peak value in late Summer of 1991 to levels that are no longer detectable with AVHRR data.

The chemical properties of these two lenslike masses of water were described by Baker et al. (1989) and clearly indicate that they were generated by massive and rapid ventings of hot hydrothermal fluid from the ridge. Both are nearly circular with radii of about 6.5 km. The isopycnals bow upward around these cores of anomalous water, leading to an anticyclonic circulation. A cyclogeostrophic balance gives maximum currents at the edge of the core of 0.11 m s (super -1) for the first megaplume (MP1) and 0.07 m s (super -1) for the second megaphone (MP2). Currents extend beyond the core to a radius of 12-15 km. The centers of the cores are in nearly solid body rotation with relative voracities of -0.5f(MP1) and -0.3f(MP2) and potential vorticity anomalies, expressed in units of equivalent relative vorticity, of -0.8f(MP1) and -0.6f(MP2), where f is the Coriolis frequency. The aspect ratio of each megaplume gives a Burger number of 0.22. In terms of these nondimensional numbers, the megaplumes are very similar to eddies of Mediterranean water found in the eastern Atlantic (meddies), despite their very different origin.

Results are presented from a study on the sex ratio of spawning populations that also examined the duration of the spawning season and the biological parameters of sexual maturity. Sampling data were collected over the period 198692. While females were predominant, immature males exceeded immature females by two to one. Gonosomatic indices and ovarian histological data indicated a potential 89-week spawning season beginning in mid-August and extending into October. Greater than 50% maturity was achieved by both sexes by age 4 yr. Sexual maturity was unrelated to size, but males were found to mature at slightly lesser length and weight than females. A 7-yr averaged spawning frequency of 8.8 d was determined, with a mean batch fecundity of 1.54 million ova.

Female cobia with ripe ovaries have been collected in the northern Gulf of Mexico from April through October. Spawning takes place throughout the summer. In order to assess changes in biochemical composition of the cobia ovary throughout the course of gonadal development, total protein, lipid, carbohydrate, and ash were measured for fish sampled on their Gulf of Mexico spawning grounds. Data are presented on cobia histology, timing of ovarian development, the gonosomatic index, and biochemistry. The analysis reveals that protein is the major constituent of cobia ovaries, which remains fairly constant throughout all stages of gonadal development. Lipid was the second most abundant component, and fluctuations could be explained by the increasing amount of lipid yolk reserves deposited as oocytes mature. Carbohydrate was the least abundant component.

A surplus production model (SPM) is developed to manage the reef fisheries of Jamaica and Belize. The fisheries of Belize have been lightly to moderately exploited, while those of Jamaica have been overexploited. Surveys were conducted of catch and effort to better quantify the model in relation to underlying assumptions. The catch and effort data were summed by area, gear type, and species group, and were standardized per km super(2) of each fishing ground. Yield from Jamaican and Belize waters was found to be 552 and 340 kg/km super(2), respectively. However, the mean fishing effort was found to be 15 times higher in Jamaica than in Belize, while the catch rate was nine times higher in Belize than in Jamaica. The composition of the fisheries was also substantially different in the two countries. Results of the SPM suggest that the Belize fishery is capable of further expansion in most areas.

In an effort to assess the extent of the problem, the foraging characteristics of sea otters were determined in relation to the length of habitat occupancy. The data evaluated, which were gathered by observation, included sex and age class, presence of pups, number of prey items obtained during foraging, and identification and categorization of prey. Statistical methods were used to assess differences in the proportion of shellfish captured among study areas and differences in forage success among study areas and adult sex classes. The percentage of clams, mussels, crabs, and green sea urchins foraged was found to be 5767, 1925, 24, and 03%, respectively. Forage success did not differ among study sites nor among sex classes. Mean forage success for all study areas combined was 89% for adults and 90% for juveniles.

Based on a 199091 sampling of commercial poundnet, haul-seine, and gillnet catches in the Chesapeake Bay and adjacent waters, annual fecundity was determined, along with spawning periodicity, size and age at maturity, sex ratios, ovarian cycle, and oocyte atresia. The sampling and analysis methods are described. Results indicated that males and females start to mature at 170 and 150 mm, respectively, and that more than 85% of both sexes are mature by the end of their first year. The spawning period was found to be JulyDecember, although individuals were found to spawn over a shorter period. Wide temporal fluctuations were found in terms of sex ratios: the frequency of males decreased in June and July, reaching a minimum in SeptemberOctober. Oocyte development appeared to be asynchronous. Spawning females exhibited a high incidence of atresia of advanced yoked oocytes throughout the spawning season.

AN - 15222190; 4830 AB - PURPOSE: The amending of the fishery management plan (FMP) for coral reefs in state and federal waters off the Florida coast is proposed. The amendment would establish special protections for live rock, a rock substrate composed mostly of calcium carbonate that supports diverse invertebrate life forms. Live rock is harvested by divers who selectively remove small pieces from the bottom either by picking up loose rubble rock or chipping rock from reefs or ledges; the rock is ultimately sold to collectors, dealers, and hobbyists for use in marine aquaria. It is estimated that in 1991, some 600,000 pounds of live rock were removed from waters adjacent to Florida. The South Atlantic Fishery Management Council has determined that removal of the live rock constitutes the removal of a fishery habitat. Under the preferred alternative, the amendment would establish an annual quota of 485,000 pounds of loose rubble rock in the South Atlantic, south of Broward-Dade County, Florida line for 1994 and 1995. Harvesting in these waters would terminate no later than January 1, 1996. No take, possession, or chipping of live rock in waters north of Dade County would be permitted. In the Gulf of Mexico harvesting would be allowed to continue through 1996 from the Florida-Alabama state line to the Monroe-Collier county line in Florida; no chipping would be allowed north and west of the Pasco-Hernando county line to the Florida-Alabama border. During the phase-out harvest period, a federal permit would be required for the harvest and possession of live rock. Permits would be limited to persons who have commercially landed and reported live rock landings prior to February 3, 1994. Some exceptions would be allowed for aquacultural harvests. Permitted vessels would be limited to 25 five-gallon buckets of live rock per daily trip. POSITIVE IMPACTS: The amendment to the FMP would protect the coral reef and hard-bottom habitats around Florida; in some areas the removal of live rock by harvesters has severely damaged the limited outcroppings or rock ledges in state and federal waters. The effects of harvest restrictions on the aquarium industry would be minimized as material from aquacultural operations replaces live rock. NEGATIVE IMPACTS: Habitat degradation would continue during the phase-out of live-rock harvesting. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), and Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

AN - 76720726; 8092995 AB - The thermodynamics of binding of fluoride and cyanide to cytochrome c peroxidase (CCP) and its Asn-82-->Asp mutant (D82CCP) in phosphate and acetate buffer at an ionic strength of 0.15 mol.kg-1 from pH 5.0 to 7.1 were investigated by titration calorimetry at 289 and 297 K. The binding reactions are enthalpically driven. The fluoride-binding constants determined from the titration calorimetry results were in agreement with those determined from difference-spectroscopy measurements. For cyanide binding to CCP at 297.9 K, the binding constant decreased from 8.95 (+/- 0.83) x 10(5) M-1 at pH 7.0 to 4.04(+/- 0.23) x 10(5) M-1 at pH 5.0, and the binding enthalpy increased from -57.2 +/- 1.4 kJ.mol-1 at pH 7.0 to -48.6 +/- 1.8 kJ.mol-1 at pH 5.0. For fluoride binding to CCP, the binding constant increased from 8.41(+/- 0.54) x 10(3) M-1 at pH 7.0 to 3.11(+/- 0.09) x 10(5) M-1 at pH 5.0 and the binding enthalpy increased from -71.9 +/- 1.1 kJ.mol-1 at pH 7.0 to -67.0 +/- 1.9 kJ.mol-1 at pH 5.0. The binding enthalpies for D82CCP were about the same as those for CCP. However, the binding constants for cyanide and fluoride to D82CCP were respectively a factor of two less and at least an order of magnitude less than the corresponding binding constants of CCP. Decreased ligand-binding strength in the D82CCP mutant is thus entirely due to entropic effects.

AN - 62743805; ED378511 AB - This report presents findings on children's living arrangements as taken from the Survey of Income and Program Participation (SIPP). The SIPP is unique in that it records how each person is related to everyone else in the household. Detailed information on parent-child relationships is provided, allowing identification of biological, step, foster, and adoptive ties. Similar data are collected for siblings. With this additional information, it is possible to examine family structure in more detail than was possible in previous Bureau of the Census reports. The statistics contained herein are based on national-level estimates of children under 18 and their living situations, for the period June through September, 1991. The report's findings pertain to all children, regardless of their marital or parental status. Included in these findings was the fact that 73 percent of children under age 18 lived with two parents, 24 percent lived with one parent, and 3 percent lived with neither parent. Black children were 2.5 times more likely to live in a one-parent family than were White children. The report examines both traditional nuclear families and nontraditional families, and includes data on children in blended families, adopted children, extended families, and other arrangements. Five figures and 12 tables summarize the data. Appendixes include an overview of the SIPP program, definitions and explanations of terms, and source and accuracy of estimates.

Using data from the Wave 5 component of the 1990 Survey of Income and Program Participation (SIPP), the report examines patterns of school enrollment, education costs, financial aid, and the associated characteristics of postsecondary students in the U.S. The report includes those enrolled in two-year and four-year colleges as well as vocational, technical, and business schools. The tabulations show the numbers of high school graduates enrolled in postsecondary institutions by a variety of demographic, social, and economic characteristics. Other tabulations show the average costs, financial aid received, net costs, and numbers of aid recipients by level of enrollment. These tabulations are crossed by gender, family income, race/ethnicity, and student dependency status. Appendices provide tabulations referring to the school year 1987-1988, an overview of the SIPP program, definitions and explanations, an analysis of the source and accuracy of the estimates and the data quality, and a copy of the questionnaire. The report's highlights indicate that the average total cost of schooling was $2,653 per student, and that among those students who received some kind of financial aid, about 75 percent of their costs were covered.

Although much of the primary literature indicates that amorphous matter is a major component of the stomach contents of Atlantic menhaden, the diet of these fish is typically perceived to consist primarily of phytoplankton and zooplankton. This disparity between observation and perception results from the belief that amorphous matter in the stomachs is the remnants of plankton that were ingested alive or that it is detritus of low nutritional value and only incidentally ingested. In this study, we found that the stomach contents of juvenile and adult Atlantic menhaden in estuarine creeks were 81% amorphous matter, 17% phytoplankton, and 1% zooplankton, by dry weight. Sampling in two estuarine creeks in North Carolina revealed no seasonal change in diet. Stomachs of fish collected from coastal waters contained smaller amounts of amorphous matter (47%) and higher amounts of phytoplankton (36%) and zooplankton (18%) than stomachs of fish from estuarine creeks. The higher concentration of plankton in the diet of fish in coastal locations probably reflects the lower concentration of suspended amorphous matter and higher relative abundance of plankton typical of that environment. In stomachs that contained largely amorphous matter, the concentrations of ash (70%, dry weight) and humic compounds (38%, ash-free dry weight [AFDW]) were high and the carbohydrate content was moderately low (14%, AFDW). On the basis of reported concentrations of these compounds in plankton and amorphous aggregates, we conclude that the amorphous matter we found in the stomachs of Atlantic menhaden was not recently ingested living or moribund plankton, but was probably material that was produced in the environment by the aggregation of dissolved organics from various detrital sources, including decaying vascular plants. If vascular plants contribute to the production of amorphous matter, their role in coastal and estuarine energy flow and fishery production may be underestimated.

Statistical Brief. AN - 62639428; ED388706 AB - Data from the Census Bureau's Current Population Surveys show that it is definitely worth, in economic terms, staying in school and earning a higher degree. This Brief examines the relationship between education and earning during the 1992 calendar year and demonstrates how the relationship has changed over the past 2 years. It also provides estimates of the total earnings adults are likely to accumulate over the course of their working lives. The more education adults received, the more money they made. Lifetime earnings estimates for seven educational levels demonstrate the large earnings differences that develop between educational levels over the long term. While high school dropouts could be expected to earn about $600,000 in 1992 dollars over a lifetime, completing high school could add about $200,000, and completing a bachelor's degree could add nearly another half million dollars. Such differences may become even more striking in the future, particularly if current trends in the consumer price index continue. Two graphs illustrate mean annual and lifetime earnings.

Analysis of the C (sub 6) + fraction constituents of natural gas is technically complex and expensive. The assembly of a physical properties database for known C (sub 6) + fraction constituents is needed to facilitate the development of improved chromatographic separation procedures for analyzing raw and processed natural gas streams for compliance with gas quality and end use specifications. This report provides a critically reviewed compilation of physical properties data for 132 hydrocarbon compounds identified as being native constituents of natural gas, 21 gas treatment compounds, and 23 gas odorant compounds. The physical properties data include: molecular mass, normal boiling point, critical temperature, critical pressure, critical density, acentric factor, triple point temperature, melting point, molar volume at normal boiling point, and refractive index. The database was compiled using information obtained from a comprehensive search of the public domain technical and patent literature using all major on-line chemical literature, patent abstract, and database services.

AN - 76629031; 8044628 AB - A rapid method has been developed to screen for planar chlorobiphenyl (CB) congeners, as well as certain other CBs and DDTs, in tissue samples from marine biota. The analytes were extracted from tissue matrices with 1:1 hexane/pentane (v/v) and interfering compounds were separated from the CBs on a gravity-flow column packed with acidic, basic and neutral silica gel eluted with 1:1 hexane/methylene chloride (v/v). Subsequently, the planar CB congeners were resolved from the DDTs and other CBs by HPLC on Cosmosil PYE analytical columns cooled to 9 degrees C and were measured by an ultraviolet (UV) photodiode array (PDA) detector. Two important advantages of PDA over conventional UV detection were the ability to identify individual analytes by comparing their UV spectra to those of reference standards and the ability to establish the spectral homogeneity (purity) of the analytes by comparing spectra within a peak to the apex spectrum. The HPLC/PDA method was tested with tissue samples from fish, shellfish and marine mammals; concentrations of certain CBs and DDTs in samples determined by screening compared favorably with those in the same samples analyzed by a comprehensive method (e.g., gas chromatography/high resolution mass spectrometry). However, the HPLC/PDA method was about an order of magnitude less sensitive than determinations by comprehensive methods.

We have selected those rocks whose compositions indicate that they are either normal mid-ocean ridge basalts (MORBs) or hotspot-type MORBs. Then we used the data base to calculate the most primitive liquidus temperature for each rock suite. The results show that the liquidus temperature of the Phanerozoic ophiolites ranges from a low of 1212 degrees C to a high of 1417 degrees C. Using these data and two exponential curves bracketing the maximum and minimum temperatures versus time, we infer that the Phanerozoic suites had a mean liquidus temperature of 1272+ or -7 degrees C and a mean temperature range of 1218 degrees to 1425 degrees C. The liquidus temperatures of Archean MORBlike greenstones range from 1305 degrees to 1576 degrees C. Using these data and two exponential curves bracketing the maximum and minimum temperatures versus time, we infer that Archean melts at 2.8 Ga had a mean liquidus temperature of 1399+ or -13 degrees C and a temperature range from 1301 degrees to 1533 degrees C. Using two different methods, we show that the change in the mean liquidus temperature since the late Archean is from 96+ or -13 degrees C (from temperature ranges) to 127+ or -20 degrees C (from temperature means). When we convert these liquidus temperatures to potential temperature of the mantle, we find that the change in the mean upper mantle potential temperature since the late Archean is from 137+ or -8 degrees C (from temperature ranges) to 187+ or -42 degrees C (from temperature means). This change is less than that which was previously thought to have occurred. We compared the liquidus temperatures calculated from our data set with an independent data set from the modern day Pacific plate. The resulting histograms have the same shape and the same temperature range, showing that our method for calculating mantle temperatures from MORBlike rocks in ophiolite suites is valid. When our calculated liquidus temperatures for all time intervals are plotted in histograms, the resulting distributions are not bimodal, but skewed unimodal. That is, the distributions show a high-T tail which results from the presence of hotspot magmas in the data set. The Archean temperature distribution is also skewed unimodal, and the high-temperature Archean rocks, such as komatiites, plot in the hotspot area of the distribution. This strongly supports the contention that komatiites do not represent "normal" Archean mantle but rather were probably erupted by hotspots. Our data suggest that the relative proportion of hotspot magmas in oceanic lithosphere has remained nearly constant over geologic time.

AN - 36406924; 4565 AB - PURPOSE: The issuance of a deep seabed mining exploration license to Ocean Minerals Company (OMCO) is proposed. The license would be in effect for ten years and apply to the Pacific Ocean equatorial high seas, roughly between Central America and Hawaii, an area known as USA-4 that was previously licensed to the Kennecott Consortium. The applicant would use existing mineral deposit data to resolve the remaining unknown factors affecting permit area delineation, perform environmental analysis of the existing data, and conduct ongoing re-evaluations of commercial development. OMCO has already compiled significant data from the USA-4 area related to mineral deposit characterization, mining system performance, and benthic biological composition. The primary efforts to be undertaken under the license would consist of specifying future development methods and schedules based on these existing data, augmented with information gathered from extensive developments in technology. The license does allow an applicant to take from the deep seabed such quantities of any hard mineral resource as is necessary for the design, fabrication, and testing of equipment to be used in the commercial recovery and processing of that mineral. However, no at-sea equipment tests would be undertaken by OMCO until a supplemental site-specific EIS were issued. No other recovery activities would be allowed under the license. POSITIVE IMPACTS: The licensed activities would provide the necessary resource, technological, and economic information for OMCO to be in a position to apply for a commercial recovery permit, should the economy warrant it. NEGATIVE IMPACTS: The worst case potential for environmental impact during exploration activities would occur from seafloor sampling with basket samplers, likely to recover up to a ton of nodules from the ocean floor. These nodules would be used for onshore testing of the collector system or in further onshore processing development tests. However, this activity would not have any significant adverse effect.

AN - 62708232; ED375310 AB - Data collected by the March Current Population Survey were used to identify which groups of year-round, full-time civilian workers aged 16 and older were most likely to be at the top and bottom of the earnings ladder. Women, young workers, less-educated individuals, and Hispanics were most likely to earn less than $13,091 (1992 constant dollars), whereas men, college degree holders, and whites were most likely to earn at least $52,364. Although more females than males have low earnings, the likelihood of having low earnings has risen faster among men than women. Consequently, the percentage point gap between males' and females' respective earning rates closed from 13 points in 1979 to 9 points in 1992. The number of low-paid workers between the ages of 18 and 24 increased 19 percentage points between 1979 and 1992. Thirty-one percent of men without a high school diploma were low earners as opposed to only 5% of those with a bachelor's degree. Thirty-five percent of men and 10% of women with at least a bachelor's degree were high earners. White women enjoyed the biggest income gains between 1979 and 1992.

Recently, a global optimization method known as the SCE-UA (shuffled complex evolution method developed at the University of Arizona) has shown promise as an effective and efficient optimization technique for calibrating watershed models. Experience with the method has indicated that the effectiveness and efficiency of the algorithm are influenced by the choice of the algorithmic parameters. This paper first reviews the essential concepts of the SCE-UA method and then presents the results of several experimental studies in which the National Weather Service river forecast system-soil moisture accounting (NWSRFS-SMA) model, used by the National Weather Service for river and flood forecasting, was calibrated using different algorithmic parameter setups. On the basis of these results, the recommended values for the algorithmic parameters are given. These values should also help to provide guidelines for other users of the SCE-UA method.

The purpose is to reduce eolian transport of dust from the Gobi Desert. Preliminary data indicate a negative trend in dust-storm frequency and duration since the 1960s. Effects on atmospheric radiation and cloud microphysics appear to be statistically insignificant in the studied period. However, only time can show any long-term impact on our environment.

We analyzed long-period surface waves and P waves recorded on the IRIS stations to estimate the fault parameters. The Centroid Moment Tensor solution shows that the focal mechanism is a thrust type with the strike parallel to the Aleutian trench. The seismic moment is 2.0X10 (super 19) Nm and the corresponding moment magnitude is 6.8. The Moment Tensor Rate Function inversion from P waves also yields a similar focal mechanism and seismic moment. In addition, this computation provides estimates of 10 s for the duration of the source time function and 35 km for the best point source depth. These seismological analyses indicate that the fault mechanism of the 1993 earthquake was as expected, but that the magnitude was too small to fill the gap. This earthquake did not generate a tsunami large enough to be observed at the Sand Point, Alaska tide gauge or at an ocean bottom pressure gauge, at distances of 100 and 300 km, respectively. Numerical tsunami simulations result in amplitudes at both stations that are within the background noise level. Additional numerical experiments also suggest that the small tsunami amplitudes are due to the location of the source area in the shallow shelf region.

AN - 36393006; 4627 AB - PURPOSE: The amending of the fishery management plan (FMP) for coral reefs in state and federal waters off the Florida coast is proposed. Under the amendment, special protections would be established for live rock, a rock substrate composed mostly of calcium carbonate that supports diverse invertebrate life forms. Live rock is harvested by divers who selectively remove small pieces from the bottom either by picking up loose rubble rock or chipping rock from reef for ledges; the rock is ultimately sold to collectors, dealers, and hobbyists for use in marine aquaria. It is estimated that in 1991, some 600,000 pounds of live rock were removed from waters adjacent to Florida. The South Atlantic Fishery Management Council has determined that removal of the live rock constitutes the removal of a fishery habitat. Under the preferred alternative, an annual quota of 485,000 pounds of loose rubble rock in the South Atlantic, south of Broward-Dade county line in Florida would be established for the 1994-1995 period. Harvesting in these waters would terminate no later than January 1, 1996. No take, possession, or chipping of live rock in waters north of Dade County would be permitted. In the Gulf of Mexico a quota of 252,000 pounds of harvesting for the 1994-1996 period would be established from the Pasco-Hernando county line to the Monroe-Collier county line in Florida; however, no chipping would be permitted in these waters and no harvesting or possession of live rock would be permitted outside this designated area. During the phase-out harvesting period, a federal permit would be required for the harvesting and possession of live rock. Permits would be limited to persons who have commercially landed and reported live rock landings prior to February 3, 1994. Some exceptions would be allowed for aquacultural harvesting. Permitted vessels would be limited to 25 five-gallon buckets of live rock per daily trip. POSITIVE IMPACTS: Under the amendment to the FMP, the coral reef and hard-bottom habitats around Florida would be protected; in some areas the removal of live rock by harvesters has severely damaged the limited outcroppings or rock ledges in state and federal waters. The effects of harvesting restrictions on the aquarium industry would be minimized as material from aquacultural operations replaced live rock. NEGATIVE IMPACTS: Habitat degradation would continue during the phase-out of live rock harvesting.

Summary data on educational attainment by age, sex, race, and Hispanic origin are shown for both years in Table 1. Other detailed data are shown for 1993 in tables 2 through 16. These tables allow the continuation of the biennial series of data from previous reports. Tables 17, 18, and 19 contain time series of data from 1940 to 1993. The detailed tables present data on educational attainment for persons aged 15 and older by age, sex, race, Hispanic origin, marital status, labor force status, occupation, income, earnings, and region of residence. Summary data are also presented for states and large metropolitan areas. Data indicate that four-fifths of adults have completed high school, and that over one-fifth have completed college. Educational levels of the population as a whole continue to rise, but there are variations by race and ethnicity. Five text tables, four figures, and 19 detailed tables present census figures.

The Scotia Sea is an outstanding example of back-arc spreading, which is revealed in some detail by free-air gravity anomaly maps derived from the latest release of data acquired south of 30 degrees S [2]. Sea surface height data for this region have been reduced to a grid of free-air gravity anomalies, and are illustrated here by means of colour shaded relief and contour maps. The new data confirm the existence of a number of inactive spreading ridges within the Scotia Sea and surrounding small basins. The amplitudes and wavelengths of gravity anomalies over these ridges conform, in general, to the expected relationship with spreading rate, except in the central Scotia Sea, where a proposed Miocene slow-spreading ridge appears to have left no clear signature. The spreading ridge axis in the east Scotia Sea comprises seven or more segments, separated by small, mainly sinistral, offsets and exhibits a median valley with depths of 200-1000 m that is reflected in free-air lows of 10-40 mGal. Near both its northern and southern termini, the gravity signature of the ridge becomes less distinct, with a less pronounced axial low. The northernmost segments of the ridge are displaced in a right-lateral sense by a feature which appears to represent a southward migrating non-transform offset. Whereas the process of spreading in Drake Passage and the east Scotia Sea was comparable to mid-ocean ridges, that in the central Scotia Sea may have been disorganized, as observed in some western Pacific back-arc basins.

This allows a more general understanding of geochemical processes in submarine hydrothermal systems, especially where a connection with sediment is not otherwise obvious (e.g., Endeavour Segment, Juan de Fuca Ridge). Based on B and delta (super 11) B corrected for wallrock reactions, all published boron and chloride data from mid-ocean ridge systems (MOR) (e.g., 11 degrees N, 13 degrees N and 21 degrees N of the East Pacific Rise), except for the Endeavour Segment, Juan de Fuca Ridge, are consistent with experimental phase separation data, suggesting a dominant control by the latter process. Fluids from sedimented ridge (SR) (e.g., Escanaba Trough and Guaymas Basin), and from back-arc basins (BAB) (e.g., Mariana Trough, Lau Basin and Okinawa Trough), when compared with mid-ocean ridge data, show expected effects of organic matter and/or sediment contributions. This is particularly noticeable from enhanced levels of Br, I, NH (sub 4) , and trace alkali metal contents (such as Li, Rb and Cs). High B concentrations and elevated delta (super 11) B in Endeavour Segment can be explained by a small, but distinguishable contribution from sediments, which is confirmed by slightly enhanced levels of Br, I and NH (sub 4) .

There are of the order of 100 individual smoker vents on approximately 10 large sulfide structures, which are localized along faults and fault intersections across the vent field. Each sulfide structure has a characteristic fluid composition, which varies very little from one vent orifice to the next, or from year to year, on a given structure. However, there are large gradients in fluid composition across the vent field, with endmember chlorinity increasing from approximately 255 mmol/kg in the SW to 505 mmol/kg in the NE. End-member concentrations of major elements are well correlated with chlorinity, and endmember volatile concentrations in the lowest chlorinity fluids are approximately twice as high as in the highest chlorinity fluids. The gradients in composition across the vent field and measured vent fluid temperatures >400 degrees C are consistent with supercritical phase separation and loss of brine phase below the seafloor. The factor-of-2 variation in CO (sub 2) (and H (sub 2) S) is larger than expected for loss of a very high-chlorinity brine. Concentrations of iron and manganese are not positively correlated with chlorinity, suggesting that temperature and pH are more important in controlling metal solubility. Elevated ammonia and bromide/chloride ratios indicate that there has been subseafloor interaction between the hydrothermal fluids and organic matter, and high boron concentrations point to a sedimentary source.

AN - 36404145; 4545 AB - PURPOSE: The amending of the fishery management plan for the Atlantic bluefin tuna is proposed. The proposed amendment would conform with recommendations of the International Commission for the Conservation of Atlantic Tunas (ICCAT), which proposed as a goal that spawning biomass should increase by 50 percent by the year 2008. This recommendation was in response to findings that the western Atlantic bluefin tuna stock was 6 to 12 percent of the levels for sustaining maximum sustainable yield. Quotas were imposed on the fishery in 1982 and they remained in effect until 1992 when a 10 percent decrease was implemented; a further stock-wide quota decrease of 15 percent was implemented in 1994. Five national quota alternatives are considered in this draft EIS, in combination with four domestic quota allocation alternatives and three access control alternatives. Under Quota A, a limit of 1,995 million tons (mt) would be imposed in 1994. It would return to the 1993 level of 2,394 mt thereafter. Under Quota B (a No Action Alternative), the current level of 1,995 mt would be retained indefinitely. Under Quota C (the ICCAT recommendation), a limit of 1,995 mt wold be retained in 1994. It would then shift to 1,200 mt thereafter. Under Quota D, the limit would shift from 1,995 mt in 1994 to 1,200 mt in 1995, and then to 800 mt thereafter. Under Quota E, all bluefin tuna fisheries would be eliminated after 1994. The domestic quota allocation alternatives include a No Action Alterative; an alternative that would permit only general and angling (fish under 70 inches) categories of fishing; an alternative that would eliminate the Gulf of Mexico incidental longline fishery; and an alternative that would close the recreational fishery. The access control alternatives would address the overcapitalization of the fishery by allocating access rights by lottery, by a limited entry scheme with a fleet-wide quota, and by individual transferable quotas. POSITIVE IMPACTS: The implementation of the ICCAT recommendations, or the imposition of similar restrictions, would help in the control of fishing mortality so as to ensure its long-term sustainability and would promote stock recovery. NEGATIVE IMPACTS: The imposition of more restrictive quotas would reduce the commercial capacity of the fishery, causing economic hardship for some users. Under the proposed amendment, the way in which the fishery is managed would be substantially changed. LEGAL MANDATES: Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801).

AN - 36403459; 4496 AB - PURPOSE: The drawdown of the Lower Granite Reservoir located along the Snake River near Almota, Washington, is proposed in order to obtain data on the biological response of anadromous fish to such a drawdown. The purpose of the drawdown is to determine whether increased mean water velocity through the reservoir resulting from a drawdown would increase juvenile salmonid survival and decrease travel time. In addition, data would be collected on the effects of drawdown on upstream passage of adult salmon, resident fish, wildlife, bottom-dwelling organisms, and water quality. These data will supplement data collected under baseline conditions and during a 1992 drawdown test. Four alternatives, including a No Action Alternative, are considered in this draft EIS; the action alternatives are differentiated on the basis of the juvenile collection and bypass method to be used at the powerhouse. Under the preferred alternative (Option 3A), a drawdown test would be implemented at the reservoir during the spring migration period (April 10 to June 20) of 1996. The dam would be operated to maximize flows through the powerhouse; a new gatewell tank system would be used to bypass fish entering the powerhouse. No water would be voluntarily spilled for fish. Any untagged juvenile fish would be transported or bypassed back to the river in accordance with current policy. POSITIVE IMPACTS: Under the preferred alternative, the project would maintain adult passage, control dissolved gas, and provide for collection of tagged salmonids at Lower Granite. NEGATIVE IMPACTS: Increased spill discharge would cause higher than normal levels of dissolved gas, silt, and water temperature. Sediment levels downstream from the dam would increase as would erosion along the riverbank.

Since these emissions are driven by the surface seawater concentration of DMS, it is important to understand the processes controlling the cycling of sulfur in surface seawater. During the third Pacific Sulfur/Stratus Investigation (PSI-3, April 1991) we measured the major sulfur reservoirs (total organic sulfur, total low molecular weight organic sulfur, ester sulfate, protein sulfur, dimethylsulfoniopropionate (DMSP), DMS, dimethylsulfoxide) and quantified many of the processes that cycle sulfur through the upper water column (sulfate assimilation, DMSP consumption, DMS production and consumption, air-sea exchange of DMS, loss of organic sulfur by particulate sinking). Under conditions of low plankton biomass (8 mu M nitrate), 250 km off the Washington State coast, DMSP and DMS were 22% and 0.9%, respectively, of the total particulate organic sulfur pool. DMS production from the enzymatic cleavage of DMSP accounted for 29% of the total sulfate assimilation. However, only 0.3% of sulfate-S assimilated was released to the atmosphere. From these data it is evident that air-sea exchange is currently only a minor sink in the seawater sulfur cycle and thus there is the potential for much higher DMS emissions under different climatic conditions.

Sea surface temperature (SST) estimates were derived using the planktonic foraminiferal transfer function FP-12E previously developed by Thompson (1981). The water depths for the cores range from 500 m to more than 4,000 m and thus provide a good opportunity to evaluate the effect of carbonate dissolution on quantitative paleotemperature estimates. The sea surface temperature time series from shallow, well-preserved cores indicate that average winter and summer temperatures during the Holocene were approximately 27 degrees C and 29.5 degrees C, respectively, for both the South China and Sulu seas. These estimates agree well with modern observations. During the last glacial maximum, summer sea surface temperatures were approximately 28.5 degrees C in the South China Sea and 29 degrees C in the Sulu Sea and thus were very similar to the Holocene. In contrast, glacial winter sea surface temperatures are estimated at approximately 21 degrees C for the South China Sea and 24 degrees C for the Sulu Sea. This decrease in glacial winter sea surface temperatures results in a much larger seasonality during the last glacial (5 degrees -8 degrees C) compared to the Holocene (2 degrees C). These seasonal contrasts are much greater than those estimated by Climate: Long-Range Investigation, Mapping, and Prediction Members (1981) for this region of the western equatorial Pacific. Variation in intensity of the monsoon system and surface water exchange rates between these basins and the open ocean are the major factors controlling glacial-interglacial SST fluctuations in the South China and Sulu seas. One factor influencing the accuracy of the SST estimates is the quality of preservation of the planktonic foraminiferal assemblages. Our results demonstrate that depth-dependent increases in dissolution result in systematically cooler SST estimates. This is due to the fact that warm water planktonic foraminifera tend to be more solution susceptible, and as dissolution progresses, the assemblage becomes enriched in the more resistant, cooler water taxa. Since dissolution is more intense during interglacials than glacials in the Pacific, dissolution tends to reduce the amplitude of the glacial-interglacial temperature difference.

AN - 36382756; 4544 AB - PURPOSE: The amending of the fishery management plan (FMP) for American lobsters in the exclusive economic zone (EEZ) along the North Atlantic coast from Labrador to Virginia and along the Outer Continental Shelf from Georges Bank to North Carolina is proposed. The FMP was implemented following the release of the final EIS in March 1983; this final supplement to the final EIS considers an amendment to the FMP which would add additional restrictions to the existing regulations to eliminate or prevent overfishing. The additional restrictions would involve freezing the minimum size limit for all lobsters at the current gauge size of 3.25 inches, thus rescinding the scheduled increase in gauge size mandated by Amendment 2; instituting a new data collection system through a mandatory, uniform logbook with detailed information on landings, fishing effort, and catch rates; establishing a moratorium on new federal vessel permits, with a formal review of the effects of the moratorium in the third year; developing a stock rebuilding program in four newly designated management areas; and revising the overfishing definition so that an area is considered overfished when the fishing mortality rate results in a reduction in estimated egg production per recruit to 10 percent or less of a nonfished population. Under the No Action Alternative, the size limits would increase one sixteenth of an inch as mandated under Amendment 2. POSITIVE IMPACTS: Under the proposed amendment, actions under the FMP would protect the lobster industry from the effects of overfishing and would delay a scheduled increase in the gauge requirements; the spawning stock size and yield per recruit would increase significantly. NEGATIVE IMPACTS: Under the proposed action, quotas on lobster landings could create a temporary economic hardship for existing lobster operations. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), and Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

Its purpose is to disseminate data developed from the National Oceanic and Atmospheric Administration's (NOAA) Estuarine Living Marine Resources (ELMR) program (see inside front cover). The ELMR program is conducted by the Biogeographic Characterization Branch of the Strategic Environmental Assessments (SEA) Division. The primary data compiled include the presence, distribution, and relative abundance of each species and the time period it utilizes each estuary. The data and framework presented are illustrative of the nationwide ELMR program. The objective of the ELMR program is to develop a consistent data base on the presence, distribution, relative abundance, and life history characteristics of ecologically and economically important fishes and invertebrates in the nation's estuaries. The data base is divided into five study regions and contains the monthly relative abundance of each species' life stage by estuary for three salinity zones (seawater, mixing, and tidal fresh) identified in NOAA's National Estuarine Inventory (NEI) Data Atlas-Volume I and supplement (NOAA 1985). The nationwide data base contains information for 135 fish and invertebrate species found in 122 estuaries. JF - NOAA/NOS STRATEGIC ENVIRON. ASSESS. DIV., SILVER SPRING, MD (USA). 1994.

In 1988, chloride-depleted (relative to seawater) diffuse fluids with low dissolved metal concentrations (relative to other mid-ocean ridge (MOR) fluids) were sampled over a distance of approximately 10 km along axis. In 1990 and 1991, both high-temperature (>200 degrees C) and diffuse vents were consistently metal- and chloride-enriched. The end-member compositions of high-temperature vents and nearby diffuse vents were very similar. There were small but significant correlated changes in diffuse and high-temperature composition from 1990 to 1991. The large-scale but temporary venting of low-chlorinity fluids over the entire North Cleft segment provides a resolution to the apparent mass imbalance implied by observations of continuous venting of chloride-enriched fluids. It is possible that a volcanic event along the North Cleft segment prior to 1987, for which there is firm geologic evidence, initially caused a boiling event which resulted in the preferential venting of vapor-enriched fluids through 1988, followed by a transition to brine-enriched fluids by 1990. High iron, low sodium, and low Sr/Ca ratios in the high-chlorinity fluids suggest that the brine phase has continued to react and approach reequilibration with an alteration mineral assemblage after the phase separation event. The absence of chloride-depleted fluids from 1990 onward, and the systematics of lithium, boron, and manganese with chloride in the high-temperature fluids from North Cleft suggest that the evolution toward lower chlorinity at Monolith vent from 1990 to 1992 is caused by progressive dilution of a brine with hydrothermal seawater.

The nest was investigated on-site by biologists from Maryland and Virginia, and was generally assumed to be a loggerhead turtle nest because of its proximity to the ocean and isolation from normal nesting grounds for freshwater and terrestrial turtles. The reported nest caused considerable media coverage and controversy, as Maryland is well out of the historical nesting range for marine turtles. Three eggs were sent to the NMFS-Charleston Laboratory for analysis of the egg yolk lipids. These data were used in conjunction with data on the size of the eggs, clutch size, and nest site for species identification purposes. It was determined that the eggs were not those of a marine turtle, but are suspected to be those of a common snapper (Chelydra serpentina). Species identification was not confirmed due to the lack of authentic snapper eggs for comparison. Though snappers have been known to wander far in their search for a suitable nest site, it is unusual to find a snapper nest on a beach in a highly urban area.

The isolated Hawaiian Archipelago contains 132 islands and reefs extending for 2400 km across the North Pacific, from Kure Atoll at the northwestern end (28 degree N, 178 degree W) to the volcanically active island of Hawaii at the southeastern extremity (19 degree N, 154 degree W). The eight large (or main) populated islands in the southeastern portion account for 96% of the coastal benthic habitats suitable for post-pelagic Hawaiian green (honu), Chelonia mydas, and hawksbill (honu-'ea), Eretmochelys imbricata, turtles. Green turtles throughout the chain migrate to breed at French Frigate Shoals at the mid-point of the archipelago (Balazs 1976, 1983). A gradual increase in the number of nesting turtles has been recorded at this site since protection was afforded in 1978 under the U.S. Endangered Species Act. About 350 green turtles nested at French Frigate Shoals during the 1993 breeding season. In contrast, nesting by hawksbills (also protected under the Act) is confined to a few remote beaches exclusively in the main islands, where only small numbers continue to come ashore to lay eggs (Balazs 1978, Balazs et al. 1992).

One of the problems that continues to handicap conservation efforts is the lack of a quick reliable method for aging marine turtles. Length measurements are used to estimate age in other species, but carapace measurements are very often hard to interpret. Measurements are not easily duplicated even if taken by the same investigator and have by nature a high potential for error. The problem is further compounded by longevity and the highly migratory nature of the species rendering the effects of conservation measures inconspicuous for many generations.

Thus, we evaluated the accuracy and precision of a directional sonic telemetry system for application in studies of sea turtle habitat use in Core Sound, North Carolina. We obtained independent bearings from multiple receiver/transmitter stations in each of three habitats of Core Sound: channel, embayment and grassbed. Known geographic locations of stations were obtained from Differential Global Positioning System. Angle errors for all three sites averaged -15 degree plus or minus 7 degree (SD) for an error arc of 14 degree . System bias, including magnetic deviation and hydrophone/compass alignment error, was corrected for before estimating point locations. Median location error was greatest in the channel (41.9 m) and smallest in the grassbed (8.9 m). Location error increased with increasing geometric mean distance between receivers and transmitters, and may have been compounded by variation in depth. Grassbeds range in size from 0.1 to 3189.0 ha in southern Core Sound. Our largest 95% confidence area was 5.7 ha. Almost 70% of the grassbeds in southern Core Sound are smaller than 5.7 ha, but represent less than 2% of the total seagrass area in the sound. Even sea turtle use of these small beds may be detected, given the contagious distribution of the beds. We have shown that directional sonic telemetry is adequate to conduct meaningful habitat use studies which could then be used to designate critical habitat, as required by the Endangered Species Act.

AN - 76532827; 8208212 AB - The measurement of absorbed dose as well as dose distributions (profiles and isodose curves) for small radiation fields (as encountered in stereotactic surgery) has been difficult due to the usual large detector size or densitometer aperture (> 1 mm) relative to the radiation field (as small as 4 mm). The radiochromic direct-imaging film, when read with a scanning laser microdensitometer (laser beam diameter 0.1 mm), overcomes this difficulty and has advantages over conventional film in providing improved precision, better tissue equivalence, greater dynamic range, higher spatial resolution, and room light handling. As a demonstration of suitability, the calibrated radiochromic film has been used to measure the dose characteristics for the 18-, 14-, 8-, and 4-mm fields from the gamma-ray stereotactic surgery units at Mayo Clinic and the University of Pittsburgh. Intercomparisons of radiochromic film with conventional methods of dosimetry and vendor-supplied computational dose planning system values indicate agreement to within +/- 2%.

AN - 62793820; ED369404 AB - After the publication of the Clinton Administration's "The National Information Infrastructure: Agenda for Action," a group of telecommunication specialists were asked to evaluate the proposals in order to broaden the policy discussion concerning the National Information Infrastructure (NII). This collection contains their visions of the nation's future information infrastructure development and their views on how the administration can best achieve its goals. The following papers are included in this volume: "Balancing the Commercial and Public-Interest Visions of the NII" (Lewis M. Branscomb); "Information Infrastructure and Economic Vitality" (Craig I. Fields); "Sustainable Democracy" (Charles M. Firestone and Katharina Kopp); "Open Sesame! How to Get to the Treasure of Electronic Information" (Francis Dummer Fisher); "Competition in Local Telecommunications (Henry Geller); "Extending Universal Service through the NII" (Susan G. Hadden, for the Alliance for Public Technology); "The National Information Infrastructure Report: A Welcome Call to Action" (Allen S. Hammond, IV); "Assembling the Pieces" (Peter W. Huber); "Toward a National Telecommunications and Information Policy: A Development-Based Vision" (Heather E. Hudson); "The Promise of the NII: Universal Service is the Key" (Mary Gardiner Jones); "Networks, Standards, and Intellectual Property: The Fabric of Information Infrastructure" (Brian Kahin); "Building Open Platforms: Public Policy for the Information Age" (Mitchell Kapor); "Public Libraries, the Public Interest, and the National Information Infrastructure (NII): Expanding the Policy Agenda" (Charles R.

Observations from camera tows and submersible dives show that the new flows are all similar in appearance and consist entirely of pillow lava with a mixture of smooth and striated surface textures, suggesting a relatively uniform eruption rate approaching 1 m (super 3) /s at point source vents. The flows vary in size from small patches to large steep-sided ridges and were probably erupted from a dike intruded along the ridge axis because they are aligned along a linear fissure/graben system. Observations at north Cleft show that the physical appearance of new flows changes more rapidly than previously realized and that earlier qualitative dating of young lavas based on sediment cover and glassy surface texture were probably overestimates by an order of magnitude. Sediment accumulation on the lavas is quite variable and locally surprisingly substantial, mainly due to hydrothermal deposits that formed while the lava flows were cooling. Biological vent communities photographed on the new flows in 1989 show that vent animals can colonize new vent sites rapidly but that warm water was still venting only in a few places. Nonvent animals are much slower to colonize the new flows and rates of colonization observed at north Cleft may be useful for making improved age estimates of young (<10 years) lava flows elsewhere. The north Cleft eruption represents about 2% of the estimated average annual volcanic output along the global mid-ocean ridge, implying that many other submarine eruptions are occurring undetected.

Several field seasons of investigations using sidescan sonar, a deep-tow camera system, and the submersible Alvin reveal that about 30 km of the ridge crest is hydrothermally active and/or has experienced recent volcanic and tectonic activity associated with this episode. The most intense hydrothermal activity within this area and all the known high-temperature vents lie along a fissure from which a young sheet flow (YSF) erupted. Extinct chimneys located within 100-200 m on either side of the fissure system represent an older (>100 years) and probably less intense, hydrothermal regime. The bathymetry and the morphology of the YSF suggest that this eruption occurred over a 1-2 km section of the fissure system that forms its eastern boundary and that it flowed to the south. Fields of lava pillars concentrated at the margins of the YSF where lava probably formed when the lava stagnated near the edges of the flow. A comparison of sidescan data sets collected in 1982 and 1987 implies that the YSF was erupted at least 7 months prior to the NPM, consistent with analysis of bottom photographs that suggests that the eruptions of the YSF and NPM were only separated by a few years. The low hydrothermal flux over the NPM relative to the YSF suggests a rapidly cooled underlying heat source beneath the former. We propose that the NPM were erupted from a dike or dikes injected laterally to the north from a magma body lying beneath the YSF. Recent evidence of a decrease in the intensity of the overlying hydrothermal plumes suggests that the system is continuing to cool down. Copyright 1994 by the American Geophysical Union.

Based on the inventories of excess (super 222) Rn, the hydrothermal heat flux was estimated to be 2.7 + or -1.3 GW in 1990. The large uncertainty results from errors in calculating the standing crop of (super 222) Rn, the difficulty in determining the (super 222) Rn to heat ratio, and the problem of entrainment of low-temperature waters into the rising plume. The high-resolution sampling program carried out in 1990 permitted the mapping of apparent plume ages for different sections of the neutrally buoyant plume. About 3 km to the east of the ridge axis there is a sharp gradient in the apparent age of the plume, while to the west the plume appears to be younger. This plume age distribution could indicate a current flow to the northwest during the time this transect was sampled. The mean (super 222) Rn/heat ratios for the high- and low-temperature vent fluids were 0.0017 disintegrations per minute (dpm) g (super -1) degrees C (super -1) and 0.0044 dpm g (super -1) degrees C (super -1) , respectively. The extrapolated end-member concentrations of excess (super 222) Rn in low-temperature vent fluids are a factor of 6 greater than the high-temperature fluids, based on the regressions of excess (super 222) Rn activity and Mg concentration in North Cleft segment vent fluid samples.

We determine the average density of the shallow oceanic crust at the ridge using seafloor gravity measurements and then use these data in conjunction with sea surface gravity observations to construct density structure models. Of 63 seafloor gravity measurements obtained, 42 observations were distributed over the 3-km left-lateral overlapping rift zone (ORZ), located at latitude 45 degrees 03'N, and separating the Juan de Fuca ridge into the Cleft and Vance segments. A 21-measurement seafloor gravity transect was made perpendicular to the ridge strike at latitude 44 degrees 52'N, a region of linear ridge geometry on the Cleft segment. These seafloor gravity measurements, which are sensitive to shallow crustal density variations, were augmented by roughly 800 km of sea surface gravity measurements. Using a bathymetry-Bouguer anomaly analysis of the seafloor gravity data, we determined the average density of the shallow (roughly upper 2 km) oceanic crust at these two locations to be 2630 kg m (super -3) + or - 50 kg m (super -3) . Within the uncertainties of the density determinations, there is no difference between the average shallow oceanic crustal density at the linear Cleft segment and at the Cleft-Vance ORZ. Using the seafloor measurements, we modeled the study area's underlying density to provide constraints on its fine-scale structure. Localized porosity of up to 17% within the upper 500 m of oceanic crust (layer 2A) provide a possible explanation for the observed gravity anomalies at the Cleft segment. Two-dimensional density models of the crust underlying the linear Cleft segment (44 degrees 52'N) show that no deep source is required to explain the topographical asymmetry observed between the east and west sides of the ridge axis. For the Cleft-Vance ORZ, three-dimensional modeling suggests low-density material between the rifts, in agreement with thickened layer 2A from seismic observations. In contrast, layer 2A variations do not explain the low density inferred at the northern end of the Cleft segment since seismic observations suggest a thin layer 2A. The magmatic activity recently observed in this region may have a distinct, deeper source. Copyright 1994 by the American Geophysical Union.

Above the hydrothermal effluent plume, which rose approximately 200 m from the seafloor, > or =90% of the (super 234) Th was dissolved, and the total (super 234) Th activity was in equilibrium with its parent uranium. This is typical of deep water for which the residence time of dissolved (super 234) Th with respect to particle uptake is greater than 200 days. Within the effluent plume, however, as little as 30% of the (super 234) Th was in the dissolved state and the residence time of dissolved (super 234) Th with respect to particle uptake was then of the order of only a few weeks. The flux (J (sub Th) ) of dissolved (super 234) Th to the particle phase was about 300 disintegrations per minute (dpm) cm (super -2) yr (super -1) . The total (super 234) Th was still approximately in equilibrium with U, indicating that the residence time of the (super 234) Th-bearing particles with respect to sinking was greater than 100 days. Particulate P, V, and As, while insignificant above the plume, attained concentrations as high as 60, 0.65, and 0.45 nmol/L within the plume. The particulate [P]/[ (super 234) Th] ratio and the (super 234) Th flux (J (sub Th) ) are used to calculate a removal flux of P resulting from hydrothermal scavenging of approximately 50 mu g cm (super -2) yr (super -1) or approximately 5.0X 10 (super 6) g P yr (super -1) per kilometer of active ridge crest. Similarly, 1.0 X 10 (super 5) g km (super -1) of V and As are removed per year from the water column by hydrothermal scavenging over this region. Extrapolation to a global scale suggests that ridge crest scavenging removes < or =10% of these elements from the ocean. Copyright 1994 by the American Geophysical Union.

Precipitate corrections for Ag, Cd, Cu, Mo, Pb, Sb, and Zn were variable, contributing an average of 20% to total solution concentrations whereas corrections for Co averaged less than 5% and essentially no corrections were required for Fe and Mn. Values for Cu, Co, and Mo in these solutions showed a strong dependence on temperature with sharp decreases in concentrations as temperatures decreased to less than 320 degrees C. In addition, and unlike most other metals studied, all vent fluids from the SJFR were almost completely depleted in Mo relative to seawater values of about 110 nmol kg (super -1) . In contrast to the Cu-Co-Mo group, concentrations of Ag, Cd, Sb, and Pb correlated well with those for Zn and are presumed to follow a distribution that is influenced less by temperature over the 246 to 332 degrees C range encountered in this study and more by the combined chemical processes that control Zn levels along the transport pathway from the deep reaction zone to the vent orifice.

I report here on temporal variability in the intensity and distribution of chronic and event plumes generated by continuous and episodic hydrothermal discharge at two vent fields on the Cleft segment of the Juan de Fuca Ridge. Hydrothermal temperature (Delta theta ) and light attenuation (Delta c) anomalies were comprehensively mapped between 1 and 4 times per year during nine cruises from 1986 to 1991. Intensity of Delta theta and Delta c in the chronic plume overlying the north Cleft vent field showed more variability between years than within a given year. Both Delta theta and Delta c were exceptionally high in 1986, fell to moderate levels during 1988 to 1990, and declined to minimum values in 1991. The chronic plume over the south Cleft vent field varied similarly. Superimposed on the chronic plumes were brief and intense releases of hydrothermal fluid that created event plumes distinguishable by their symmetry and exceptional rise height. Event plumes at the north Cleft field ranged from the 1986 megaplume, with a rise height exceeding 1000 m, to smaller events in 1987 and 1989 with rise heights of approximately 400 m. Chronic hydrothermal heat (660 + or - 277 (1sigma ) MW) and mass (204 + or - 86 (1sigma ) g s (super -1) ) fluxes from the north Cleft field were determined by assuming these fluxes were equivalent to the long-term net advection of a mean cross-section of the vertically integrated Delta theta and Delta c in the plume. This 6-year history of hydrothermal plumes indicates that episodic discharge has been an important component of the recent hydrothermal flux and that the aggregate heat and mass fluxes declined significantly, though not consistently, between 1986 and 1991.

The data set includes observations of focused and diffuse venting fluids and neutrally buoyant plumes formed by chronic and episodic venting. Manganese/heat and iron/heat ratios for plumes from the north end of the Cleft segment were combined with independently determined estimates of plume heat flux to yield annually averaged chronic venting fluxes for Mn of 0.36 + or - 0.17 mol s (super -1) and for Fe of 0.61 + or - 0.34 mol s (super -1) . Over 6 years of plume measurements at North Cleft segment, observed episodic hydrothermal discharge accounted for -15% of the total vented Mn and -35% of vented Fe. The chronic fluxes for Mn and Fe at a second venting center located at the south end of the Cleft segment were estimated to be approximately equal to the fluxes at North Cleft segment. Chronic plumes at North Cleft segment are mixtures of focused and diffuse discharge that contribute heat, Mn, and Fe in variable proportions. Similar examination of South Cleft segment data strongly suggests the presence of an as yet unobserved venting source relatively depleted in Mn and Fe but contributing substantially to the overall heat. Temporal and spatial variations in the concentrations of Mn and Fe and in Mn/heat and Fe/heat ratios for focused seafloor vents were difficult to resolve within complex chronic plumes. Manganese/heat and iron/heat ratios of megaplumes suggest they may have derived from reservoirs of diffuse fluids while smaller event plumes may have formed by different processes and have properties similar to chronic plumes. The accurate assessment of segment-scale hydrothermal fluxes of Mn and Fe requires coordinated measurements of representative seafloor sources and the neutrally buoyant plume that integrates all seafloor discharge.

These data determine the average velocity structure of the upper crust and map the thickness variability of the shallow low-velocity layer, which we interpret as the extrusive volcanic layer. The experiment is unique because a large number of travel times were measured along ray paths oriented at all azimuths within a small (20 km by 35 km) area. These travel times provide evidence for compressional velocity anisotropy in the upper several hundred meters of oceanic crust, presumed to be caused by ridge-parallel fracturing. Compressional velocities are 3.35 km/s in the ridge strike direction and 2.25 km/s across strike. Travel time residuals are simultaneously inverted for anisotropy as well as lateral thickness variations in the low-velocity layer. Extrusive layer thickness ranges from approximately 200 m to 550 m with an average of 350 m. The zone of the thinnest low-velocity layer is within the northern Cleft segment axial valley, in a region of significant hydrothermal activity. Layer thickness variability is greatest near the Cleft-Vance overlapping rift zone, where changes of 300 m occur over as little as several kilometers laterally. These low-velocity layer thickness changes may correspond to fault block rotations in an episodic spreading system, where the low side of each fault block accumulates more extrusive volcanics.

In the rising buoyant plume, >75% of the P, V, Cr, and As scavenging from seawater by hydrothermal precipitates occurs in the first 50 m above the vent. Cu and Zn are most enriched in buoyant plume particles collected from the first few meters above the vent. However, the degree of enrichment decreases very rapidly with increased height above the vents due to sedimentation of the more dense Cu- and Zn-rich sulfide phases. Using the plume data, coupled with the results of our analysis of sediment trap samples, we estimated that more than 99% and 99.9%, respectively, of the total hydrothermal Fe and Mn produced at the vent field are transported beyond the vent field and dispersed in the open ocean.

Indexed XRD lines are tabulated: strongest lines 2.863(100), 2.653(50), 2.388(50), 2.771(40), 2.272(30), 1.832(30) Aa; a 9.068, b 17.992, c 14.486 Aa, beta 104.86 degrees ; space group P2 (sub 1) /c, Z = 2. The structure may be viewed as being composed of layers of vertex-sharing TO (sub 4) tetrahedra (T = Si,Be,Zn) alternating with layers of vertex- and edge-sharing CaO (sub 8) bicapped trigonal prisms and MnO (sub 6) octahedra, the layers being (102). The TO (sub 4) groups and CaO (sub 8) -MnO (sub 6) groups share vertices with one another across the layer boundaries to form the three-dimensional structure. Within the layers of tetrahedra, the TO (sub 4) groups form a network of 4-, 5- and 8-membered rings. The P2 (sub 1) /c space group may only represent an average structure, the true structure having lower symmetry due to ordering of Zn and Be on separate sites. The name is for Dr. Samuel Fowler (1779-1844), the pre-eminent figure in the Franklin mining district.

The mitogenic response of English sole leukocytes was assessed for a variety of mitogens. In vitro culture conditions for English sole leukocytes that would maintain cellular viability and allow leukocytes to proliferate were initially determined with an undefined medium. Factors that were varied to create an effective mitogen assay included mitogen type (pokeweed mitogen, concanavalin A, phytohemagglutinin, and lipopolysaccharide), mitogen concentrations, incubation time and temperature, medium supplementation, and number of leukocytes per culture. A leukocyte concentration of 1 10 super(7) leukocytes/mL provided for the greatest proliferation; cell concentrations above or below this level resulted in less proliferation. A higher degree of proliferation occurred when the leukocytes were incubated with fetal calf serum than with heatinactivated autologous plasma. It was confirmed that leukocytes were responsible for proliferation of the Splenic whole-cell population in response to mitogens. Pokeweed mitogen and lipopolysaccharide were able to stimulate English sole leukocytes to proliferate at ITC. However, phytohemagglutinin and concanavalin A were generally unable to induce cellular proliferation. The ability of pooled leukocytes to produce a tridirectional MLR was also examined once effective culture conditions were determined via the mitogen assay. Mixed leukocyte reactions were negative or borderline positive when leukocytes from three English soles were cultured.

Sea turtle meat and eggs were also important foods for the early settlers. Turtling was undoubtedly one of the first commercial fisheries in the southeastern United States not only because sea turtles were abundant, but also because of the relative ease of capture when laying eggs on deserted beaches. Also, no boats, nets, or other expensive equipment were needed, and the turtles could be easily kept alive until sold. The commercial fisheries for the now threatened and endangered species of sea turtles in U.S. waters have been neither adequately described nor analyzed in detail. In this paper, I describe the U.S. sea turtle fisheries and summarize the commercial sea turtle landings reported in Federal fishery documents for the continental United States, Puerto Rico, and Hawaii. These important baseline fisheries data on threatened and endangered species of sea turtles provide considerable insight into the sociology and economics of the U.S. sea turtle fishery.

Traditional measures of nominal effort can lead to biased performance measures since fishing effort is a multidimensional concept not readily captured by nominal measures. This paper evaluates the source of growth in catch over time according to its constituent components - the growth accounting framework - to measure trends in catch, nominal and effective effort, and productivity or fishing power. An empirical study of the US Pacific coast groundfish trawl fishery indicates that traditional measures of effort and fishing power can be biased and highlights the relative importance of growth in productivity or fishing power as an often overlooked and perhaps the most important source of growth.

The cause of this die-off is unknown but current hypotheses point to environmental stress making this seagrass susceptible to disease. The potential exists for colonization and recovery of these die-off patches but the sequence of events and the persistence of the recovery have not been evaluated. Based on an existing model that represents theoretical successional steps toward the Thalassia climax, four habitat types were sampled in each of two basins of western Florida Bay. Data demonstrated a high potential for recovery of the denuded die-off patches. The alga Batophora oerstedi is the first colonizer with replacement by other algal species and subsequently Halodule wrightii and eventually Thalassia. Under the existing conditions of high resuspended carbonate sediment and biological turbidity, which are thought to be secondary responses of the system to the die-off of seagrasses, persistence of the colonizing habitats and the climax community itself is tenuous.

Subsequent visits in 1993 revealed that the sample sites were devoid of seagrasses.

Ophiura sarsi and American plaice were sampled during a 1-yr period (1985-1986) from a site of 148-156 m depth. The bimodal size-frequency distributions of the O. sarsi population were dominated by small individuals with disk diameters between 2 and 11 mm, and with estimated growth rates, based upon the modal progressions from the persistent 1985 year class, of ) 4 mm per year. Larger individuals () 15-25 mm) were generally less numerous. These older brittle stars, which formed the right-hand peaks of the size-frequency distributions, displayed little noticeable growth, which suggests that these peaks were comprised of multiple cohorts. Recruitment to the population appeared to be continuous, due to the occurrence of 1 mm or smaller brittle stars throughout most of the year. The strong presence of 1 mm or smaller O. sarsi in January, 1986 indicated a major recruitment event. A survey of the reproductive condition of the gonads showed evidence of continuous but seasonally variable reproduction, with the major spawning centered around January. O. sarsi was the major dietary constituent of the American plaice, occurring in at least 65% of the fish stomachs throughout the year. Plaice consumed the most abundant size classes of O. sarsi in the population, with disk sizes between ) 4 and 10 mm. These brittle stars were of low caloric value, yet the more nutritious, older brittle stars were not eaten in significant numbers by even the largest plaice. The high proportion of small, energy-poor O. sarsi found in the plaices' diet might be the result of their greater abundance of accessibility at this site.

Summit depth, harvest area, amount of shallow habitat, and latitude were considered in relation to pre-exploitation research catch rates and 6 years of commercial fishery landings. A threshold between lobster production and the depth of bank summit was observed; banks with summits deeper than 30 m yielded few lobsters. The effect of benthic habitat relief was then examined for three selected, bathymetrically similar banks, two commercially productive and one unproductive. Percent cover of habitat variables with characteristic relief such as sand, algae, and coral outcrops were measured on each of the banks during 70 scuba dives. Juvenile lobster stages were found significantly associated with habitat scale. The nonlinear relationship indicated both high and low extremes in relief yield poor catch per unit of effort (CPUE). Only the variable intermediate relief (5-30 cm) was associated with high sublegal lobster CPUE. The two productive banks had much more benthic relief at this scale than did the unproductive, suggesting that the abundance of intermediate relief habitat represents a bottleneck to adult lobster production.

Males born in 1987 tended to weigh less at age 3 and 4 yr than those born in other years. Weights of individuals at ages 2, 3, and 4 yr were significantly correlated with their weights as pups (P < 0.05). Weights at ages 2 and 3, 3 and 4, and 4 and 5 yr were significantly correlated (P < 0.001), although weight changes with age were highly variable. Data indicate that larger than average male pups born during 1987-1990 were more likely to survive, but this effect was less evident than among pups born during 1960-1965 when average pup weights were lower.

Spawning began as early as May when eggs and larvae occurred off Cape Hatteras, advanced northward with time, peaked in July when eggs and larvae occurred as far north as Cape Cod, and ended in late August. Unlike earlier studies that argue for multiple and distinct spawning seasons, this 11-year study concludes that spawning in the NCSE represents the continuation of a protracted season that begins in late winter in slope waters off the southeastern United States and progresses northward with time. Results add to a growing block of evidence that supports a unit stock designation for the bluefish population along the east coast of the United States.

Pupping, lactation, weaning, and molting were directly observed, while mating was rarely observed and was, therefore, inferred from the occurrence of mounting injuries and from adult male and female association patterns. Pooled birth rates during the study period were 0.544 for all adult-sized females and 0.675 for females parous in earlier years. For parturient females, pupping peaked in late March and early April, weaning in May, mounting injuries in May and June, and molting in July. For non-parturient females, the median mounting injury and molting dates occurred 17 and 28 days earlier, respectively. Pupping date set the timing of subsequent events in the annual cycle, but the timing of those events was adjusted by loss of the pup or poor physical condition of the female. Individual pupping patterns varied widely. The mean interval for births in consecutive years was 381 days; females that pupped in consecutive years gave birth later each season. Conversely, females who skipped a year or more gave birth earlier their next pupping season.

Klinowska (1991) states that "the stock in the northeast Pacific is believed to be near extinction, possibly represented by no more than a few individuals." On 24 March 1992, Southwest Fisheries Science Center observers encountered on North Pacific right whale at 32 degree 14'N, 118 degree 42'W, while conducting an aerial census for marine mammals. This location is 70.4 km southwest of the southeast tip of San Clemente Island, and 47 km southeast of Cortes Bank. The water depth at this location is ) 1,700 m. Diagnostic features observed that allowed positive identification of this right whale were as follows: body black, back smooth without dorsal fin, upper jaw arched and lower lip strongly bowed, numerous callosities on the head and lower jaw, V-shaped blow, and wide tail flukes.

The cause of this decline is not known. A life table for the northern sea lion was calculated assuming that life spans follow a Weibull distribution. Samples of northern sea lions taken in the vicinity of Marmot Island, Alaska during 1975-1978 and 1985-1986 indicate that the average age of females older than 3 yr increased about 1.55 yr (SD = 0.35 yr) while the population was declining at about 5% per year. Fecundity rates decreased by 10% over the same period, but the decrease was not statistically significant (Calkins and Goodwin 1988). Possible causes of the population decline and the change in age structure were examined by writing the Leslie matrix population equation in terms of changes in juvenile and adult survival rates and fecundity, and examining the short-term behavior of the trajectories of the average age of adult females, total number of females, and total number of pups with respect to those changes in the vital parameters. From the observed rate of declines of adults and the changes in average age of adult females and fecundity, estimates of the changes in adult and juvenile survival were calculated; estimates of the standard deviations of these changes were estimated via a bootstrap procedure. One purpose of this exercise is to aid in setting priorities for research for determining the cause of the decline. An explanation for the observed declines in numbers of adult sea lions consistent with the observed fecundity rates, a rate of decrease of 5% in the number of adults, and the corresponding increase in average age (of females age 3 yr and older) was a 10%-20% decrease in the survival of juveniles (age 0-3 yr) coupled with an insignificant change in adult survival (0.03%, SD = 1%).

Ribonucleic acid (RNA) and deoxyribo-nucleic acid (DNA) content during embryogenesis were compared to temperature and embryo age. Hatching time, larval size, yolk-sac volume, and RNA content at hatching were inversely related to incubation temperature. DNA content and RNA/DNA ratios of larvae were similar on the day of hatching at all experimental temperatures. The energetic reserves available during embryonic and prolarval development are enhanced by lower incubation temperatures. Prolarvae reared at 12 degree C had high rates of yolk utilization and initial growth, but experienced reduced growth and a decline in DNA content prior to feeding initiation. The effects of food availability on nucleic acid content and RNA/DNA ratios of first-feeding walleye pollock were determined. Mean RNA and DNA content and RNA/DNA ratio of fed larvae were significantly higher than those of unfed larvae after 2 days. Starvation of larvae that had successfully initiated feeding resulted in a rapid decline of RNA content (and RNA/DNA ratio) accompanied by a slower decline in DNA.

Data collected during more than 6,500 hours of monitoring at 106 structure removals in 1992 provided information on sea turtle distribution. Eighteen individuals were observed including 10 loggerheads, 2 leatherbacks, 1 hawksbill, and 5 unidentified sea turtles. The observation rate (individuals per monitoring hour) of sea turtles was about 30 times higher during aerial surveys than during day or night surface surveys.

Benthic prey were collected during 1983-1985 from seven areas in the Bight apex. These areas were selected because they span a range of habitat quality conditions in the Bight apex, and fish dietary information was available. Another area outside of the Bight apex was used as a reference, since it was expected to be affected minimally by waste disposal. Benthic taxa collected from each area were selected because of their common use as prey in the results of prior or concurrent fish and American lobster diet studies. There were no major changes in disposal practices within the Bight apex during the sampling period. Only sub-adult (<2 cm carapace width) Atlantic rock crabs, Cancer irroratus, were sampled as they were the size usually eaten and were assumed to be less motile and most associated with each collection area, so that metal concentrations found would reasonably reflect overall exposure within each area.

The Dover sole, Microstomus pacificus, differs from the other local flatfish species by undergoing an extensive ontogenetic vertical migration, occupying all depth zones at different life stages, and having its maximum spawning biomass in the oxygen minimum zone between 600 and 1000 m. Size-activity relationships and depth-activity relationships for the glycolytic enzyme lactate dehydrogenase (LDH) and for two enzymes associated with aerobic metabolism, malate dehydrogenase and citrate synthase (CS), were examined in white-muscle tissue of shallow-living, deep-living and ontogenetically-migrating species. Scaling coefficients (b) for weight-specific enzyme activity (log activity) = a + b (log wet weight), varied in sign as well as magnitude for fishes living at different depths. In the shallow-living California halibut Paralichthys californicus, LDH scaled positively (0.39) and CS scaled negatively (-0.15) with size, a pattern observed previously for most shallow-water fish species. The permanently deep-living species, the deep-sea sole Embassichthys bathybius, differed in that both LDH and CS scaled strongly negative (-2.0 and -1.5, respectively). For the ontogenetically migrating Dover sole Microstomus pacificus, there was a shelf-slope transition. For the shelf specimens ( less than or equal to 200 m), LDH scaled positive (0.11) and CS negative (-0.29) and for the slope specimens ( greater than or equal to 400 m), LDH scaled negative (-0.65) and CS strongly negative (-0.63). Rex sole, Glyptocephalus zachirus, showed a similar shelf-slope transition. Intraspecific depth-enzyme activity differences were not incremental, but changed abruptly between the continental shelf stations (100 to 200 m) and the continental slope (400 to 1400 m). Based on comparisons with laboratory-maintained individuals, the decline in the metabolic capacity of the white muscle of Dover sole is a phenotypic response to the low food and oxygen conditions of the continental slope. Contrary to expectation, anaerobic capacity (LDH activity) decreased in response to low oxygen conditions, suggesting that in a permanently hypoxic environment such as the oxygen minimum zone the metabolic strategy may be to not incur an oxygen debt that would be difficult to pay back.

Chemical oxygen demand (COD) was significantly reduced by bubbling ambient air through the sediment for 6 to 10 h. Combined treatments lowered the sediment oxygen uptake to a level which was not statistically different (p < 0.0001) from 0.2 mu m filtered seawater. The described method is useful for sufficiently reducing sediment oxygen consumption (BOD and COD) to measure respiration of infaunal organisms, including ophiuroids, bivalves and polychaetes, in a more natural, buried setting.

Prior to 1960, the two stocks were fished exclusively by the United States. During the 1960s, marked increases in exploitation occurred due to the development of Canadian and distant-water fisheries on Georges Bank. Total landings from the two stocks increased from 14 400 t in 1960 to 57 500 t in 1966, but subsequently declined to 30 000 t in 1976. Under extended fisheries jurisdiction - enacted in 1977 by both the USA and Canada - landings and stock sizes initially increased and a record-high catch (71 000 t) was attained in 1982. However, during the late 1980s and early 1990s, fishing effort and fishing mortality also increased to record-high levels, resulting in marked reductions in spawning-stock size. Research vessel indices, commercial c.p.u.e. indices, and VPA results all indicate that biomass levels in both stocks are now at record-lows. Although it is clear that fishery-induced perturbations have had a major impact on the Georges Bank and Gulf of Maine stocks, environmental and biotic influences may also have affected the stocks. These influences are not easily discernible, given the magnitude of the fishery-induced changes. Biophysical processes appear to be extremely important during the first year of life of cod and affect growth, mortality, and year-class strength. These processes are reviewed and discussed in relation to their impacts on various life history stages of cod. Current and future research studies aimed at differentiating environmental from fishery-related factors affecting recruitment and abundance of cod in the Georges Bank-Gulf of Maine region are discussed.

This is presumably due to a reduction in the thickness of the diffusion boundary-layer which allows for a higher carbon availability on the plant surface. Blades of the seagrasses Thalassia testudinum and Cymodocea nodosa exposed to different current velocities under controlled laboratory conditions, showed increased photosynthetic rates with increasing flow only at low current velocities (expressed as blade friction velocities, u sub(*)). Carbon saturation of photosynthetic processes occurred at a relatively low u sub(*) level (0.25 cm s super(-1)) for T. testudinum collected from a calm environment compared to C. nodosa (0.64 cm s super(-1)) collected from a surf zone. No further enhancement of photosynthetic rates was observed at higher u sub(*) levels, suggesting limitations in carbon diffusion through the boundary layer below critical u sub(*) levels and possible limitations in carbon fixation by the enzymatic system at higher u sub(*) levels. These results, as well as those of previous theoretical studies, assumed the flow on the immediate seagrass-blade surface to be hydrodynamically smooth. The presence of epiphytes and attached debris causes the surface of in situ seagrass blades to be exposed to flows ranging from smooth to rough-turbulent. As a consequence, the boundary-layer thickness on moderately epiphytized blades under medium to high flow-conditions is not continuous, but fluctuates in time and space, enhancing carbon transport. In situ u sub(*) levels measured directly on blades of seagrass indicate that T. testudinum and C. nodosa can be exposed to conditions under which the boundary layer limits photosynthesis during short periods of time (milliseconds) during low-energy events. As waves cause the thickness of the diffusion boundary-layer to fluctuate constantly, carbon-limiting conditions do not persist for prolonged periods. JF - Marine biology.

Cytochemical measures of lysosomal responses in the digestive cells using automatic image analysis AN - 16628843; 3668120 AB - Lysosomal responses in the digestive cells of Mytilus edulis from 9 sites in Puget Sound, Washington, USA, with varying degrees of sediment contamination were measured using automatic image analysis. Mussels from urban-associated sites (areas with elevated sediment concentration of anthropogenic contaminants such as PAHs, PCBs, DDTs, and toxic elements) showed pathological changes in the lysosomes (reduced lysosomal labilization period, reduced lysosomal stability and increased N-acetyl beta -hexosaminidase activity), enhanced lipofuscin deposition and increased accumulation of lysosomal and cytoplasmic unsaturated neutral lipids. Morphometric measures of growth showed that mussels were generally smaller in size and that somatic tissue weight relative to shell length was lower in mussels from urban-associated sites relative to those from minimally contaminated sites. Highly significant correlations were observed between concentrations of tissue PAH, PCB, and selected toxic elements (measures of anthropogenic exposure) and lysosomal labilization period. Pathological alterations in the lysosomal system of mussels from the urban-associated sites were probably induced by the high tissue concentrations of organic and inorganic contaminants rather than as a result of potential confounding biotic (spawning stress) or abiotic (temperature, salinity and food availability) factors. The results show that cytochemical measurement of lysosomal responses combined with automatic image analysis have the potential to be used as sensitive, accurate and rapid techniques for assessing the biological impact of environmental contaminants in mussels in the near coastal environment.

Home ranges extended from 954 to 28833 km super(2) while core areas varied from 89.6 to 4,279 km super(2). Core areas included several petroleum and gas structures that may have been visited on a daily, weekly or monthly basis. Average submergence times of loggerheads ranged from 4.2 min in June to 171.7 min in January. The number of submergences per day was inversely proportional to duration of submergences per day. Loggerheads spent, on the average, over 90% of their time under water in any given season. Bottom depth location of the loggerheads was significantly correlated to Galveston's mean air temperature (-0.56 < r < 0.28) and mean sea surface temperature (-0.72 < r < 0.25). Correlation was higher (-0.58 < 4 < 0.60) when temperatures were regressed against distance from shore. Mean swimming speeds of these loggerheads were from 0.4 to 1.4 km/h, with over 95% of the values < 5 km/h.

Increased use of atrazine in the 1970s coincided with a decline in the abundance of Zostera marina L. (eelgrass). Groundwater surveys have found atrazine in concentrations that may affect eelgrass growth and survival. The effects of atrazine in groundwater discharges on the growth of eelgrass through root-rhizome exposure were examined in laboratory systems. A long term, dynamic, groundwater simulation study was conducted with atrazine concentrations ranging from 0.0 to 2.5 mg/l. No significant effects on chlorophyll content, growth or survival were detected. A static root-rhizome exposure experiment was conducted using split chamber exposure systems to verify these results, atrazine concentrations were increased by an order of magnitude. Neither mortality nor significant effects on plant growth were detected (maximum atrazine concentration 7.6 mg/l. A static, whole plant exposure experiment was conducted, and mortality was observed at atrazine concentrations of 1.9 mg/l and above. This work suggests that eelgrass is not susceptible to atrazine through root-rhizome uptake, and that atrazine exposure via groundwater seepage did not cause the declines in eelgrass abundance and distribution.

A major milestone was reached in advancing toward a more ecologically based management practice when the majority of coastal nations of the world endorsed the declaration made at the United Nations Conference on Environment and Development (UNCED) in 1992, to prevent, reduce, and control degradation of the marine environment, so as to maintain and improve its life-support and productive capacities; develop and increase the potential of marine living resources to meet human nutritional needs, as well as social, economic, and development goals; and promote the integrated management and sustainable development of coastal areas and the marine environment. The scientific framework in support of the UNCED objectives is now emerging from a series of regional efforts aimed at cross-sectoral integration of research, monitoring, and assessments conducted to mitigate stresses on coastal ecosystems from toxic effluents, habitat degradation, nutrient loadings, harmful algal blooms, aerosol contaminants, and losses of living resources from pollution and overexploitation. Discipline-oriented ecological studies can contribute more toward achievement of resource sustainability when they are conducted within a framework of science at the level of organization that is multidisciplinary and focused on populations, habitats, and ecosystems at large spatial scales. Primary, secondary, and tertiary driving forces of variability in biomass yields are examined for several large marine ecosystems, along with observations on changing states of 'health' of the systems. Marine resource problems underscored by UNCED are being addressed. Post-UNCED large marine ecosystem-scale programs for advancement toward resource sustainability, ecosystem health, and economically viable biomass yields are now being implemented. The programs are being supported by international agencies as part of an effort to couple recent advances in ecological monitoring, management, and stress mitigation strategies from the more developed countries, with the lesser developed coastal countries around the margins of the ocean basins.

AN - 15221917; 4427 AB - PURPOSE: The implementation of a management plan to protect the habitat of late-successional-forest- and old-growth-forest- related species within the range of the northern spotted owl is proposed for lands managed by the Forest Service (FS) and the Bureau of Land Management (BLM) in the Pacific Northwest and northern California. Ten action alternatives developed by the Forest Ecosystem Management Assessment Team are considered in this final supplement to the final EIS of January 1992 supplementing a final EIS issued by the FS for the Pacific Northwest region, and six draft EISs issued by the BLM in August 1992 for individual districts in Oregon. The No Action Alternative was considered unreasonable and could not be implemented. Under the preferred alternative (Alternative 9), a management direction would be established that corresponds with the plan announced by President Clinton in July 1993. Approximately 7.32 million acres of forest reserved by Congress as national parks, wildlife refuges, and other specially designated areas, would be retained; another 7.43 million acres would be managed as late-successional reserves. Some level of silvicultural treatment would be permitted in stands less than 80 years old in the West in order to accelerate the development of old-growth-habitat characteristics, but all actions would require review by the Regional Ecosystem Office. The salvage of dead trees would generally be limited to areas where catastrophic losses exceeded ten acres in the East. Approximately 1.48 million acres would be managed as adaptive management areas; each of these areas would have a different emphasis in its prescription, such as maximizing the amount of late-successional forests or improving riparian conditions through silvicultural treatments. Ten areas of federal land ranging in size from 92,000 to 500,000 acres have been identified as adaptive management areas. Approximately 2.63 million acres would be managed as riparian reserves, providing a buffer along all streams, wet areas, ponds, lakes, and unstable and potentially unstable areas. Finally, roughly 3.98 million acres would be managed as matrix areas, in which some levels of timber harvesting and other silvicultural treatment would be permitted. POSITIVE IMPACTS: The protection of old-growth habitat under the preferred management scheme would ensure the continued existence of the endangered northern spotted owl, the marbled murrelet, and other species dependent on late-successional forest and old-growth forest. The proposed limitations on timber harvesting would benefit the watershed, fisheries, and soils. Similarly derived benefits would redound to recreational resources, cultural resources, and Native American religious sites. NEGATIVE IMPACTS: Some old-growth forest stands would be harvested under the preferred alternative. A reduction in harvest activity would take place, however, which would cause the loss of jobs and income and could threaten the economic vitality of timber-dependent communities.

AN - 36409106; 4425 AB - PURPOSE: The amending of the fishery management plan (FMP) for the harvest of sablefish off the coasts of Washington, Oregon, and California is proposed. The amendment would establish an individual quota program to cover the harvest of sablefish by vessels with groundfish limited-entry permits for longline and fishpot gear. The harvest of sablefish by trawl gear in the license limitation fishery or longline, fishpot, and other gear by unlicensed vessels in the open access fishery is not covered by the proposed individual quota program. The fixed-gear sablefish individual quota program designed by the Pacific Fishery Management Council would allocate sablefish quota share, which is a percentage of the total annual harvest guideline, to persons based primarily on catch history. Each year, holders of quota share would be allocated an amount of sablefish individual fishing quota, which is an amount of sablefish pounds for the year based on the amount of quota share held, which could be taken anytime during the fishing season. To be affected by the quota, a vessel or a person must have recorded at least one landing of sablefish or groundfish with fixed gear between August 1, 1988 and November 13, 1991. A quota share (a percent of the total annual harvest guideline) would be allocated to owners of ""A'' permits based on catch history extending back to January 1, 1984. Each year holders of quota share would be allocated an individual quota representing the pounds of sablefish catchable in that year. After a quota share is initially issued, anyone eligible to own a U.S. documented fishing vessel would be eligible to purchase or otherwise acquire a quota share from one of the initial recipients. These eligible parties would include, but not be limited to, vessel operators, crew members, processors, and banks; foreign-controlled entities would not be eligible. Caps would exist on the amount of quota controlled by a single person or used on a single vessel. Persons with individual fishing quotas could be required to be aboard the vessel when the sablefish are caught. A small amount of unused individual quota could be carried over from one year to the next. The monitoring and enforcement of individual quotas could entail restrictions on where and when vessels might land sablefish, requirements for advanced notice of landings, and other rules designed to ensure compliance with the program. The estimated annual costs of the enforcement program range from $450,000 to $575,000, and the estimated start-up costs of the administrative program are approximately $2.0 million. The only other alternative under consideration is the status quo arrangement, allowing common access to sablefish among fixed gear license holders. POSITIVE IMPACTS: Under the proposed amendment to the FMP, the sablefish industry would be protected from the effects of overfishing. Processing and marketing costs would be lowered by giving processors more control of scheduling. NEGATIVE IMPACTS: An individual quota system could increase the discard rate and discard mortality because of an interest in retaining only high-grade fish and a shift from fixed gear to longline gear. Groups or individuals who did not qualify for quota allocation would be put at a permanent disadvantage in the market; affected parties could include foreign interests, vessel owners denied an initial allocation, and corporations and partnerships owning processors.

It was found that in 1990, 14 percent of the population 5 years and older spoke a language other than English at home, as contrasted with 11 percent in 1980. Languages spoken most commonly at home in descending order of percentage, were: Spanish; French; German; Chinese; Italian; Tagalog (Pilipino); Polish; Korean; Vietnamese; Portuguese; Japanese; Greek; Arabic; Hindi (Urdu); and Russian. For these languages, total numbers spoken in 1980 and 1990, and percentage changes, are charted. A map of the United States indicates percentages of the population in each state that speak a language other than English at home. It was found that slightly more than half of all non-English-speakers in the United States reside in three states: California; Texas; and New York. Data are also provided on the distribution of English language skills (speaks English not at all, not well, well, or very well) within the population that speaks a language other than English at home.

AN - 36412346; 4446 AB - PURPOSE: The implementation of a fishery management plan (FMP) for corals and reef-associated plants and invertebrates in state and federal waters off Puerto Rico and the U.S. Virgin Islands is proposed. The plan would cover over 100 species of coral (including stony corals, sea fans, and gorgonians), and 60 species of plants (including seagrasses) and invertebrates (including live rock, a rock substrate that supports diverse invertebrate life forms). Many of these resources are being harvested by the relatively new and expanding fishery for the marine aquarium industry. The corals and coral reefs are of enormous value for the reef communities that they support, for their physical capacity to protect coastlines, and for the aesthetic value. Under the proposed plan, regulations for management would prohibit the harvesting or possession of stony corals, sea fans, gorgonians, and certain species associated with live rock, live or dead, except for legally permitted research, education, and restoration; prohibit the sale or possession of any prohibited species unless fully documented as to point of origin; prohibit the use of chemicals, plants, or plant-derived toxins, and explosives to harvest organisms, except for legally permitted research, education, and restoration programs; limit the harvesting of other invertebrates to hand-held dip nets, slurp guns, and hand and other non-habitat-destructive gear, except for legally permitted research, education, and restoration programs; require invertebrate harvesters to obtain permits and report harvesting results; and establish a marine conservation district south of St. John, where all harvesting would be prohibited. Under the FMP, the states would also be directed to establish permitted anchoring sites in coral reef areas; identify habitats of critical concern; expand data collection efforts; regulate diving operations; and regulate the discharge of untreated sewage and petroleum products into coastal waters. POSITIVE IMPACTS: Under the proposed FMP, the reef and seagrass habitats around Puerto Rico and the U.S. Virgin Islands would be protected. In addition to being a valuable biological resource, these habitats have commercial, medical, and recreational importance; significant damage to reef habitats would endanger commercial fishing opportunities in the area. NEGATIVE IMPACTS: Although the conservation measures would eventually benefit the commercial fishing industry, aquarium fish industries would experience increased operating costs once the proposed gear restrictions were in place.

AN - 36406428; 4439 AB - PURPOSE: The amending of the fishery management plan (FMP) for the American lobster is proposed in the exclusive economic zone (EEZ) along the North Atlantic coast from Labrador to Virginia and along the Outer Continental Shelf from Georges Bank to North Carolina. The proposed amendment would be designed to eliminate or prevent overfishing by adding additional restrictions to the existing regulations. Three alternatives, including a No Action Alternative, are considered in this draft EIS. Under the proposed action, the additional restrictions would involve freezing the minimum carapace size limit for all lobsters at the current gauge size of 3.25 inches, thus rescinding the scheduled increase in gauge size mandated by Amendment 2; instituting a new data collection system through a mandatory, uniform logbook with detailed information on landings, fishing effort, and catch rates; establishing a five-year moratorium on new federal vessel permits, with a formal review of the effects of the moratorium in the third year; instituting a new requirement for an operator's permit for operators of fishing vessels engaged in the fishery; requiring several categories of federal vessel permits and limits on lobster landings according to the permit category; developing a stock rebuilding program, addressing all segments of the harvesting sector, in response to an assessment that the stock is overfished, in four newly designated management areas; and revising the overfishing definition so that an area is considered overfished when the fishing mortality rate results in a reduction in estimated egg production per recruit to 10 percent or less of a nonfished population. Under the two other alternatives, the minimum size requirements would increase beyond the 3.25 inch limits. POSITIVE IMPACTS: Under the proposed amendment to the FMP, the lobster industry would be protected from the effects of overfishing. A scheduled increase in the gauge requirements would be delayed. Significant increases in the spawning stock size and yield per recruit should result. NEGATIVE IMPACTS: The proposed quotas on lobster landings could create a temporary economic hardship for existing lobster operations. LEGAL MANDATES: Coastal Zone Management Act of 1972, as amended (16 U.S.C. 1451 et seq.), and Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

AN - 76793799; 7952943 AB - The lack of rapid, high throughput assays is a major obstacle to many aspects of research on marine phycotoxins. Here we describe the application of microplate scintillation technology to develop high throughput assays for several classes of marine phycotoxin based on their differential pharmacologic actions. High throughput "drug discovery" format microplate receptor binding assays developed for brevetoxins/ciguatoxins and for domoic acid are described. Analysis for brevetoxins/ciguatoxins is carried out by binding competition with [3H] PbTx-3 for site 5 on the voltage dependent sodium channel in rat brain synaptosomes. Analysis of domoic acid is based on binding competition with [3H] kainic acid for the kainate/quisqualate glutamate receptor using frog brain synaptosomes. In addition, a high throughput microplate 45Ca flux assay for determination of maitotoxins is described. These microplate assays can be completed within 3 hours, have sensitivities of less than 1 ng, and can analyze dozens of samples simultaneously. The assays have been demonstrated to be useful for assessing algal toxicity and for assay-guided purification of toxins, and are applicable to the detection of biotoxins in seafood.

AN - 76792371; 7952945 AB - Domoic acid (DA) was first reported in mussels from Prince Edward Island, Canada, in 1987. It reappeared in anchovies and pelicans from Monterey Bay, California, in 1991. Later that year, domoic acid was found in razor clams and Dungeness crabs along the Washington and Oregon coasts. Since the initial outbreak, a variety of analytical methods for the detection of this neurotoxin have been developed. Here, we describe a modification to the solid phase extraction (SPE) clean-up step in Quilliam's HPLC-UV method (1991: NRCC No. 33001). The standard 10% acetonitrile (MeCN) wash and 0.5M ammonium citrate buffer (ACB) in 10% MeCN (pH = 4.5) eluting solution have been replaced with a 0.1M sodium chloride (NaCl) in 10% MeCN wash and a 0.5M NaCl in 10% MeCN eluting solution. This modification allows the analysis to work equally well on both clam and crab viscera and meat. Chromatograms of visceral samples no longer contain interfering or late eluting peaks; and all chromatograms are free of the large solvent peak tailing associated with the ACB eluent. The newly modified method allows for an improved and more versatile domoic acid analysis.

There are many areas as large as the state of Oklahoma where no depth measurements are available. Satellites carrying radar altimeters have measured the shape of the ocean along tracks only 3-4 km apart, and from these data we can make very accurate and high resolution maps of the marine gravity field. The gravity field mimics the seafloor topography in the 15-160 km wavelength band if sediment cover on the ocean floor is thin. Long-wavelength (greater than 160 km) topography is isostatically compensated and is not correlated with the gravity field. In addition, the satellite gravity field and the available depth measurements were used to determine the correlation between gravity and the seafloor topography. By applying this correlation to the gravity field we predict seafloor topography in the 15-160 km wavelength band. This topography is combined with a long-wavelength component estimated directly from ship depth measurements. The result reveals many new features and is within + or - 100m of actual depths in many cases. The GEOSAT gravity data has been used in combination with this algorithm to produce a 36" x 48" color poster. A color, polar stereographic view of the Predicted Seafloor Topography is now available from the National Geophysical Data Center. The image is also available for viewing on Mosaic. The digital data from which this color image was generated is available from the National Geophysical Data Center. The Predicted Seafloor Topography is an inferred data set and is not true bathymetry. It is, however, the best estimate of seafloor topography available resulting from satellite gravity data and actual ship depth measurements. This data is intended for scientific research and should not be used for navigational purposes. Additional software is required in order to manipulate the data or produce your own graphic images. The coverage for this data base is 30 degrees S - 70 degrees S. The grid spacing is 3 minutes of longitude by 1.5 minutes of latitude (7200 x 1600). The present format is a GMT/netCDF binary grid file. In this format the file is about 47 megabytes.

In 1992, Chile's economy grew 9.7 percent, while unemployment fell to under 5 percent. Strict fiscal discipline, increased exports, growth in consumption, privatization of state-run businesses, and the opening of the economy to imports stimulated this growth. Economic growth, unfortunately, has taken an incredible toll on Chile's natural environment. Air, water and soil pollution are common in both industrial areas and major cities. Due to the highly visible nature of Chile's air pollution problem and an abundance of land, solid waste pollution has not been at the forefront of the pollution control sector. As the new law and accompanying regulations develop, opportunities will emerge, mainly for incinerators, hazardous waste treatment, and waste separation and recycling systems.

Despite its present cold climate, the Arctic land masses once lay much farther to the south and were gradually carried northward by plate tectonic motions. For example, in the Late Carboniferous northern Greenland, which was part of Pangea, was situated at only 30 degrees N with the Panthalassa Sea to the north. By Late Jurassic-Early Cretaceous, a series of allochthonous blocks had collided with both the North American and Siberian plates. The Pacific Ocean was separated from the Arctic Basin by rotation of the North-Slope Chukotka block counterclockwise away from the Canadian Arctic Islands by Mid Cretaceous. It is speculated, based on the magnetic patterns, that the Alpha-Mendeleev Ridge complex may either have been a separate precursor block or may represent oceanic crust modified by a hot spot. Sea floor spreading in Late Cretaceous or Early Paleocene rifted the presentMakarovBasin in a wedge-shaped manner, with the Siberian end wider than the Canadian. The Eurasia Basin has a well-ordered set of magnetic anomalies, and thus this basin can be confidently dated to have been created just after the Cretaceous-Tertiary boundary. Creation of the Eurasia Basin eventually opened the pathway for exchange of waters between the Arctic and Atlantic oceans. The cold-oxygen rich waters from the Arctic ventilate the world's oceans and provide an important mechanism for global heat transfer and for the cycling of nutrients and carbon.

P. Lee Cruise L3-84-SP) AN - 52132651; 2002-024186 AB - Reconnaissance geophysical and geological surveying was conducted at Valu Fa Ridge, a back-arc spreading center in Lau Basin, to assess the potential for hydrothermal venting. A high-amplitude, phase-reversed reflection 1.5 s beneath the ridge axis was imaged on seven multichannel seismic reflection profiles. This reflection event is interpreted as the top of an axial magma chamber which may continuously underlie Valu Fa Ridge from at least 21 degrees 53'S, 176 degrees 30'W to 20 degrees 40'S. 176 degrees 45'W. Elevated concentrations of (super 3) He and particulate and dissolved Mn obtained at a single hydrocast station above the ridge crest suggest the regional presence of hydrothermal venting at Valu Fa Ridge. The sea floor is characterized by porous volcanic rubble which favors a diffuse, low temperature style of venting. Temperature anomalies in the near-bottom water detected during towed camera runs, and the recovery of hydrothermal smectite provide additional evidence for hydrothermal activity.

The hydrological and meteorological conditions that led to the flood were unique, complex, and extreme in many aspects. A brief description of the hydrometeorological setting that led to The Great Flood of 1993 is presented. Also presented is a summary of the human and economic impacts of the flood. In view of the magnitude of the losses, it is clear that every effort must be taken to reduce potential future losses. Many lessons already have been learned from The Great Flood of 1993. Foremost among these is the need to accelerate the implementation of an Advanced Hydrologic Prediction System. The major components of this advanced prediction system are presented and comparisons are made between forecast capabilities employed during The Great Flood of 1993 with those that will be possible once an Advanced Hydrologic Prediction System is in place. A significant functionality of the advanced prediction system must be more effective linkage of meteorological and climatological forecast and outlook information with the hydrologic forecast system. This is especially important for future precipitation. Inability to adequately incorporate precipitation forecasts was the single largest source of error for the longer-term hydrologic forecasts during The Great Flood of 1993. One approach for improving this deficiency as part of an Advanced Hydrologic Prediction System is described.

The proximity of significantly elevated isopycnals to the deep fluorescence maxima suggests that the out-cropping density surfaces represented paths along which particulate matter was transported. In one specific case, a relict-chimney (observed during a three-dimensional survey near the ice edge) appeared to have transported cooled, saline water of Atlantic origin and its associated biomass to mid-depths along inclined isopycnals. It is postulated that enhanced surface cooling necessary to establish deep isopycnal outcropping within the euphotic zone coupled with the high rate of particulate matter generation in the spring represents the primary mechanism by which the observed biogenic material was vertically transported to depth. The spatial and temporal scales over which biogenic transport occurs range from several km (chimneys) to hundreds of km (northern front of the Greenland Sea) and days to weeks.

Pre-shift and post-shift time differ in that precession-driven variations become more important in the late Quaternary; at the same time the 100 kyr cycle becomes dominant. A number of possible explanations have been put forward to explain the change in character of climatic fluctuations, calling on non-linear feedback mechanisms within a steady-state system, among which are ice-mass responses to extreme size increase (such as basal melting) and extension of lowland ice over shelves, where marine downdraw becomes possible. Here we emphasize the role of the unidirectional modifications of land morphology by ice erosion (as proposed by Nansen) as a factor in generating deep shelves (e.g., Barents Sea), valleys for channelling of ice, and uplift providing for mountain peaks where a new ice buildup can begin after an interglacial has run its course. Also, we consider that increased positive feedback from variations in albedo and atmospheric carbon dioxide is important, and we present evidence for a significant role of ocean circulation (Nordic heat pump) for the time after the Mid-Pleistocene Revolution.

To date, these comparisons have come mainly from ice-core data, which show a strong correlation between past atmospheric CO (sub 2) concentration and polar temperature. A new method is presented for reconstructing atmospheric CO (sub 2) concentration using the (super 1) 3C/ (super 1) 2C ratio (delta (super 1) 3C) in mosses and sedges in peat. The method exploits the fact that, unlike sedges and most other plants, mosses do not possess stomata, and are therefore unable to regulate their uptake of CO (sub 2) and water. The delta (super 1) 3C of mosses thus depends on both atmospheric CO (sub 2) concentration and available water, and the delta (super 1) 3C of sedges from the same peat can be used to remove the water signal. The method provides a resolution of about a decade--much higher than is possible from ice cores. Initial results for the past 14,000 years show three sharp increases in atmospheric CO (sub 2) concentration: at 12,800 years ago, corresponding to an episode of warming in the North Atlantic region; 10,000 years ago, corresponding to the end of the Younger Dryas cold period; and 4,400 years ago, after which time modern climates were established globally.

Organisms present at total suspended matter concentrations as low as 10mg/l released enough organic compounds during 1 day to negate the initial removal of the hydrophobic dissolved organic matter by Sep-Pak columns. In these experiments, the coating of particulate inorganic surfaces with organic matter may have also prevented Cu from establishing a chemical equilibrium between these particulate surfaces and the solution. The behavior of added radioactive Cu is consistent with an equilibrium model if the transfer of organic matter between dissolved and particulate phases by organisms is considered. In contrast, the behavior of natural Cu in these biotic suspension indicate that the partitioning of Cu was controlled as much by active biological processes as by chemical equilibria.

Estuarine particulate matter was suspended in two solutions: (1) filtered seawater, and (2) filtered seawater in which the hydrophobic organic matter had been removed. Radioactive Cu was then added to each suspension. The removal of hydrophobic dissolved organic matter resulted in a two-fold increase in the distribution coefficient (K (sub D) ) of added radioactive Cu (from 10 (super 4.50) to 10 (super 4.81) l/kg). The partitioning of (super 64) Cu in the suspensions was controlled by chemical processes dominated by complexation with particulate and dissolved organic matter.

The spreading corridor southwest of Fracture Zone XII is characterized by a rift valley and an usually small subsidence constant of 226 + or - 13 m/m.y.1/2, while the two spreading corridors immediately northeast of Fracture Zone XII have an axial high and a subsidence constant consistent with the global average. This abrupt variation in ridge morphology is not usually characteristic of medium-rate spreading centers, nor is such an abrupt variation expected of adjacent ridge segments that are spreading at the same rate. We suggest that a thermal anomaly beneath the ridge may influence the first-order effects of spreading rate and lithospheric cooling enough to produce the observed rift valley and axial high and the different subsidence constants. Although we are not certain what would produce the thermal anomaly here, we speculate that when the spreading rate on the Pacific-Antarctic ridge increased from slow to intermediate rates since 20 Ma, so did the need for materials for accretion, which may be supplied in part by along-axis asthenospheric flow from hotspots or a hot region to the northeast. A sufficient supply of hot asthenosphere may still be lacking in the ridge segment with the axial valley to the southwest, leaving it cooler and starved for accretionary materials.

Corrections for variations in atmospheric angular momentum (AAM) significantly reduce the scatter of the measured amplitudes across both time and frequency. The AAM corrections are found to reduce the scatter in the observed tidal amplitudes by as much as 60% for periods as short as 5.6 days; in contrast, earlier studies have shown a loss of coherence between AAM and length-of-day (LOD) for periods shorter than about 10 days. The tidal amplitude measurements place bounds on both the nonequilibrium ocean and mantle anelasticity effects. The in-phase k/C determination is found to agree to better than 0.5% with the value of 0.944 from Yoder et al. (1981). The out-of-phase values are found to have a frequency dependence that can only be explained by nonequilibrium ocean effects. The observed slope is larger than the theoretical by about 3 times the expected error. This result may indicate that the ocean is farther out of equilibrium for the higher frequencies than present models permit. Significant improvements are needed in both ocean and atmosphere modeling to exploit the full capability of the VLBI observations. Copyright 1994 by the American Geophysical Union.

A study was completed to determine if the JUP possibly could be used for conservation storage for any number of days from April 15 through May 14 under certain hydrologic conditions. The methods of the study were: (1) Frequency analysis of recorded daily mean discharge data for streamflow-gaging stations upstream and downstream from Pueblo Reservoir, and (2) Implementation of the extended streamflow prediction (ESP) procedure for the Arkansas River basin upstream from the reservoir. The frequency analyses enabled estimation of daily discharges at selected exceedance probabilities (EP's), including the 0.01 EP that was used in design of the flood- storage capacity of Pueblo Reservoir. The ESP procedure enabled probabilistic forecasts of inflow volume to the reservoir for April 15 through May 14. Daily discharges derived from the frequency analyses were routed through Pueblo Reservoir to estimate evacuation dates of the JUP for different reservoir inflow volumes; the estimates indicated a relation between the inflow volume and the JUP evacuation date. To apply the study results, only a ESP forecast of the April 15-May 14 reservoir inflow volume is needed. Study results indicate the JUP possibly could be used as late as May 5 depending on the forecast inflow volume. JF - Water-Resources Investigations - U. S.

The results are compared with CBL heights determined from radiosonde measurements. The profiler provides continuous CBL height measurements with very good time resolution (30 minutes or less), allowing for detailed understanding of the growth and fluctuations of the CBL. In addition, the profiler provides information about the degree of definition of the CBL top and the thickness of the entrainment zone. The measurements discussed were taken during the Rural Oxidants in the Southern Environment II (ROSE II) experiment.

The purpose of the calorimeter, design functions, and inherent limitations of a particular design are discussed. The interactions between the hood structure and the fire and its plume are analyzed in the context of avoiding: flame impingement on the hood; enhanced combustion of a test article, over and above that of a free-burn; loss of combustion product plume gases due to spill-over below the hood; and unacceptable dilution of plume gases in the measurement section of the exhaust duct. The concept of the ideally designed hood is introduced, where, throughout the course of the burn of a test article the hood is always immediately above the flame tip and the exhaust rate always exactly matches the hood-ceiling- elevation plume-flow rate. Methods to partially or completely achieve the ideal design are presented. These include the combined features of adjustable hood elevation and adjustable hood exhaust rate.

The early commercial sea turtle landings were sporadically collected and were published in a series of U.S. Government fisheries documents. Unfortunately, they have never been collated and summarized into a single data base or document. These are important base-line fisheries data on U.S. threatened and endangered species of sea turtles and provide considerable insight into the sociology and economics of the turtle fishery. Additionally, these data also provide basic biological information, such as species composition, seasonality, and sizes. These factors are necessary for understanding the ecology of these unique reptiles and enable resource managers to formulate sound management and conservation strategies, as mandated by the Endangered Species Act of 1973, and subsequent amendments. In this report, the author summarizes the commercial U.S. sea turtle landings as reported by he U.S. Fisheries Commission, Bureau of Commercial Fisheries and National Marine Fisheries Service for the continental U.S., Puerto Rico, and Hawaii.

The effect was calculated for a binary alloy. The dependence of the interface kinetic coefficient on crystallographic orientation is based on the motion and density of steps. Anisotropic kinetics give rise to travelling waves along the crystal-melt interface, and can lead to a significant enhancement of morphological stability. This self-stabilization arises because the travelling step density wave. The stability enhancement increases as the orientation approaches a singular orientation and as the solidication velocity increases. Specific calculations were carried out for Ge-Si alloys.

The sanctuary Management Plan identifies 4 goals: resource protection, research, interpretation, and visitor use. The sanctuary staff have identified 3 key uses of a geographic information system (GIS) that will help achieve these goals: site characterization, monitoring, and disaster preparation. A GIS--in this case, a marine GIS--is a tool that the sanctuary staff can utilize to map resources and analyze the effects of man or nature on the environment of the sanctuary.

For most estuarine-dependent fish populations, the earliest (age 0) life stages are most sensitive to changes in habitat quality. The difficulty for fishery managers lies in relating changes in age 0 survival rates to changes in abundance of older ages. Eggs-per-recruit (EPR), measured as the potential lifetime fecundity of an age 1 female, is used to compare the effects of changes in age 0 survival and fishing mortality rates on the reproductive potential of three fish species that are estuarine-dependent: winter flounder (Pleuronectes americanus), stripped bass (Morone saxatilis) and shortnose sturgeon (Acipenser brevirostrum). For striped bass and shortnose sturgeon, small changes in fishing mortality rates can have the same effect on reproductive potential as large changes in age 0 survival rates; whereas for winter flounder, changes in age 0 survival rates and fishing mortality rates of approximately the same magnitude have equivalent effects on reproductive potential. The difference in the relationships of age 0 survival and fishing mortality rates to reproductive potential between winter flounder and the other two species is because winter flounder have fewer age groups vulnerable to fishing mortality, an earlier age of full maturity, and higher total mortality rate than either striped bass or shortnose sturgeon.

This is somewhat less than the mass loss reported for territorial adult male pinnipeds. During fasting, absolute rates of mass change (averaging -0.68 kg/day) were positively correlated with initial mass. Mass-specific rate of change (averaging 2%/day) did not vary with age or initial mass. Although they lose large amounts of mass while fasting, immature male fur seals achieve a net increase in mass during the breeding season by making feeding trips to sea. We postulate that the capability for prolonged fasting in immature males facilitates the development of social and sexual skills that are likely to increase future reproductive success.

Some computer models for oil spill prediction can be useless in actual spill incidents because they cannot operate with the limited amount of input data available in an emergency or because their output cannot directly answer questions posed by spill response personnel. Moreover, weathering models typically idealize a spill incident to such an extent that the results of a simulation may bear little resemblance to what happens in a real spill. We conclude that the key features of any oil-weathering model are: flexibility in the input requirements, ease-of-use, computational speed, uncertainty estimates of the model predictions, and output display based on possible spill response decisions. We discuss the design criteria used in the construction of ADIOS, incorporating the above factors, as well as computational constraints due to choice of platforms on the numerical solutions of the weathering algorithms. Model results for a recent spill are reviewed. JF - SOCIETY FOR COMPUTER SIMULATION, P.P. BOX 17900, SAN DIEGO, CA 92177 (USA). pp. 56-60. 1994.

This probability can be calculated under the assumption that the initial velocity and launching angle of a fragment are uniformly distributed random variables. Since air drag cannot be neglected in most practical cases, equations of motion must be solved numerically to compute this probability. This paper presents an implementation of a procedure for calculating this probability. JF - SOCIETY FOR COMPUTER SIMULATION, P.P. BOX 17900, SAN DIEGO, CA 92177 (USA). pp. 84-90. 1994.

Part of that testing included participation in HYGRO'93 where field testing of the SeaBat-9001 was conducted in the Bay of Fundy, New Brunswick, Canada, on board the R/V Mary-O and the CHS Vessel Frederick G. Creed. Based on HYGRO'93 data, the SeaBat-9001 was determined to have a slant range precision of 2.55 centimeters. Comparison between SeaBat-9001 data collections from the Mary-O and the Creed showed excellent agreement with less than 100cm super(2) variance between surveys conducted of the same area on different days. It is concluded that the SeaBat-9001, when appropriately integrated into a survey system, can satisfy the applicable shallow water standards of the International Hydrographic Organization.

In each year, divers collected all mussels within a 0.5 m super(-2) frame, with 10 replicate quadrats being sampled at each station. In the southeastern portion of the lake where mussels have been established since 1988, densities in 1992 were similar or lower than densities found in 1990. On the other hand, although still lower than densities in the southeastern portion of the lake, densities in the northwestern portion of the lake increased between 1990 and 1992. The size structure of mussel populations in the two regions were quite different. For similar substrate types (unionids), mussels less than 5 mm in shell length comprised 53% of the population in the southeastern portion of the lake compared to only 20% in the northwestern portion. The latter region has colder temperatures and lower food supplies than the former region. Over the entire lake, the maximum density at an individual station was 11,000 m super(-2) in 1990 and 25,000 m super(-2) in 1992. JF - IAGLR, BUFFALO, NY (USA). 166 p. 1994.

This is especially important because epizootiologic studies have shown a positive association between environmental carcinogens, such as polycyclic aromatic hydrocarbons, and increased prevalence of neoplasms and related lesions, primarily in liver, of benthic fish species (Microgadus tomcod) (Pseudopleuronectes americanus) from a wide range of urban and industrialized areas. In studies with wild fish and mammalian species the super(32)P-postlabeling assay, as developed for aromatic compounds, has been used most extensively because of its high sensitivity and ability to detect structurally uncharacterized adducts. The results to date of field and laboratory studies show that hepatic DNA adducts detected in fish are associated with increased exposure to environmental polycyclic aromatic compounds in the preponderance of species examined, whereas in the limited studies with wild mammals, such a relationship is equivocal at present. The findings with fish suggest that DNA adducts, as measured by super(32)P-postlabeling, have the potential to be effective molecular dosimeters of exposure to environmental carcinogenic aromatic compounds and thereby may lead to an improved understanding of the etiology of neoplasia in wild teleosts.

Accurate determination of the cyclone center position, based on Doppler velocity measurements, will become essential for the issuance of hurricane advisories, forecasts, and warnings once a network of WSR-88D Doppler radars is deployed on the United States coastlines, islands, and military bases during the 1990s. This will allow high-resolution detection and tracking of hurricanes nearing land for the first time. Simulated Doppler velocity data, which were reconstructed from wind field data collected by reconnaissance aircraft during Hurricanes Alicia (1983) and Gloria (1985), were used to test the concept of using ground-based Doppler radar data to estimate cyclone center location. The center range and azimuth estimates of a hurricane signature were calculated from the simulated coastal Doppler radar velocity data. Preliminary results indicate that the technique performed well for estimating center locations from the radar measurements compared with storm center positions determined from in situ aircraft measurements.

B-cell mediated immunity was assessed by examination of the primary and secondary plaque-forming cell (PFC) responses of anterior kidney and splenic leukocytes to a T-independent antigen, trinitrophenyl-lipopolysaccharide (TNP-LPS) and to a T-dependent antigen, TNP-keyhole limpet hemocyanin (TNP-KLH). Salmon exposed to DMBA at dosages of 20% or 1% of the 96 hr LD sub(50) (12.7 mg and 0.6 mg/kg of salmon, respectively) or to PCBs at a dosage of 20% of the 96 hr LD sub(50) (54.0 mg/kg of salmon) exhibited a suppressed PFC response. The secondary PFC response of anterior kidney and splenic leukocytes to both antigens and the primary splenic PFC response to TNP-LPS were suppressed in salmon exposed to either DMBA or PCBs. However, only the primary PFC response of anterior kidney leukocytes to TNP-LPS was suppressed in salmon exposed to PCBs and no suppression of this response was observed in salmon exposed to DMBA. Neither anterior kidney or splenic leukocytes from salmon exposed to DMBA or PCBs showed an altered primary PFC response to the T-dependent antigen, TNP-KLH. These results suggest that B-cell mediated immunity in salmon is suppressed by known mammalian immunosuppressants and that suppression of the PFC response observed previously in salmon from an urban estuary may be due to contaminant exposure.

Isochrysis isolates are from several geographic locations, and their relationships to each other are not known. Research reports of Isochrysis growth characteristics, biochemical composition, and nutritional value to invertebrates suggest that a number of these strains differ in terms of their taxonomy and fundamental biology; their practical use as mariculture feeds differs as well. In this note, we discuss origins of some of these strains, describe differences between these from our own and others' research, and recommend that researchers be cognizant of the cultural history of their Isochrysis strains because differences between them will affect their use as mariculture feeds.

Nehlsen et al. (1991) identified over 200 stocks they considered to be at some risk of extinction and over 100 already believed to be extinct. Major federal stock restoration programs are under way in the Columbia and Klamath River basins, and several populations of Pacific salmon have recently been listed as threatened or endangered under the U.S. Endangered Species Act. Although there is widespread agreement that recovery programs are needed for Pacific salmon, there is less agreement over what constitutes recovery.

As part of this project, zebra mussels (Driessena polymorpha) have been collected at 13 sites along the shores of the Great Lakes from Green Bay through Lake Huron to the western end of Lake Erie. Three samples of approximately 250 large specimens each were obtained from each site, and each was analyzed for concentrations of 70 contaminants including 12 trace metals and 4 major elements. The levels of a number of the metals, generally those most used in industrial processes, were clearly different among the various sites. Higher concentrations of these metals were found downstream from the major industrialized areas with concentrations of 4 to 7 times at the most contaminated sites compared to the sites further removed from anthropogenic sources.

AN - 16979167; 3627691 AB - There is considerable evidence that different classes of chemical contaminants which accumulate in subtidal sediments are responsible for a variety of serious biological effects in marine organisms exposed to such compounds. While much of this information is derived from laboratory studies, there is an increasing body of data from field studies which supports such relationships between contaminants in subtidal sediments and biological damage. Accordingly, there is a desire to reduce the exposure of marine organisms to chemically contaminated sediments, and various methods for doing this have been proposed. The most common approaches rely on either removal of sediments by dredging, or some type of physical sequestration of sediments, generally through the placement of a cap over contaminated areas. A question which has not been adequately addressed is whether or not such treatments will result in a lessening of the risk to living marine resources. A major focus of this presentation will be a discussion of the development and appropriate use of technologies for assessing the efficacy of subtidal sediment remediation. Areas to be discussed in detail include the use of screening technologies for rapidly assessing contamination of sediment and biota, and the use of biomarkers to expedite the determination of biological injury to marine species. Examples will be given of the use of these techniques in Puget Sound, Washington, USA, where several subtidal sites have undergone or will be undergoing remediation.

Modifications to the model permitted radiative effects of the smoke plume to modify the pollutant's vertical mixing. Calculated SO sub(2) (sulfur dioxide) air concentrations were compared with the observations from several intensive aircraft measurement compaigns as well as longer-term ground-based measurements. Model sensitivity tests and comparison to the aircraft measurements confirmed (1) the magnitude of the tabulated emission rates for SO sub(2) and carbon soot; (2) the most appropriate value for the smoke's specific extinction coefficient was about 4 m super(2) g super(-1); (3) that the model was sensitive to the vertical mixing in the first 100 km downwind from the fires; (4) that the SO sub(2) conversion rate was about 6% h super(-1); and (5) although there were large variations in the height of the initial smoke plume and ground-level concentrations were most sensitive to that height, an average value of 1500 m a.g.l. (above ground level) provided reasonable model predictions. Six ground-level sampling locations, all along the Arabian Gulf Coast, were used for model evaluation.

A technique was developed to analyze NOAA polar orbiting satellite imagery to obtain horizontal smoke plume positions. The plume heights were obtained by combining the satellite analysis with back trajectory results. Backward trajectories were computed using both coarse and fine resolution MRF wind fields. The average of the absolute value of relative trajectory error (vertical bar R.T.E. vertical bar) for the late summer period (24 July-15 September 1991) was about 10% of the travel distance when using the fine grid trajectories with the optimum plume centroid height and 14% when using the coarse grid model output. The absolute R.T.E. for the optimum plume height runs was half of the R.T.E. for the constant starting height run (vertical bar R.T.E. vertical bar = 0.21). This difference indicates the importance of proper specification of plume centroid height when using high resolution meteorological data for transport studies. Use of the standard coarse grid MRF wind fields to drive the transport model was shown to lead to large errors near the source due to the poor horizontal and vertical resolution.

Laboratory and field studies show tunas are not strictly prisoners of their own thermoconserving mechanisms, but have rapid and extensive control over the efficacy of their vascular countercurrent heat exchangers. Skipjack tuna (Katsuwonus pelamis) are, therefore, probably not forced out of formerly suitable habitats as they grow because of the potential for overheating, as formerly thought. Because of their thermoregulatory abilities, bigeye tuna (Thunnus obesus) apparently can exploit food resources well below the thermocline by minimizing rates of heat loss when in cold water, and then maximizing rates of heat gain from the environment during brief upward excursions into the warmer mixed layer. Widely cited estimates of limiting oxygen levels, based on estimated metabolic rates at minimum hydrostatic equilibrium swimming speeds, are not accurate because tunas have exceptionally high oxygen demands even at slow speeds. High metabolic rates, even at slow swimming speeds, most likely result from the high osmoregulatory costs engendered by tunas' large thin gills and/or their other adaptations for achieving exceptionally high maximum metabolic rates. Recent laboratory research and modelling efforts suggest the capacity of tunas' cardiorespiratory systems to deliver oxygen at extraordinarily high rates was evolved to allow rapid recovery from strenuous exercise, rapid digestion, and high rates of gonadal and somatic growth, not high sustained cruising speeds. The rate at which reduced ambient oxygen levels prolong the time required for tunas to recover from strenuous exercise appears to be a good index of habitat suitability, with respect to oxygen.

In each of 3 years, photoperiod treatment began in late December or January and continued for 13 to 18 weeks until release between 29 March and 5 April into the Clearwater River. Additional groups exposed to either the advanced photoperiod or ambient light were reared at an elevated water temperature (11-12 degree C) for 10 to 14 days preceding release. Downstream movement and recovery proportions were evaluated using passive-integrated-transponder (PIT) tags. Photoperiod treatment increased gill Na super(+)-K super(+) ATPase levels significantly at the time of release in 2 of the 3 study years and in all 3 years resulted in significantly faster travel times to Lower Granite Dam, 117 km downstream. The combination of photoperiod and increased temperature treatment resulted in the highest gill Na super(+)-K super(+) ATPase levels at release, the fastest downstream movement, and significantly higher recovery proportions downstream. Temperature treatment alone had no effect on gill Na super(+)-K super(+) ATPase level or recovery proportion and resulted in significantly slower travel time to Lower Granite Dam. Treatment groups exhibiting faster travel time to Lower Granite Dam also passed McNary Dam (343 km downstream) sooner, although the differences were not as great.

Corresponding to this increase, researchers and fishermen have observed an increase in the incidental capture of harbor seals in GOM sink gillnet fisheries. At the same time the perception among some fishermen is that harbor seal predation on commercially important groundfish is significant. During this period groundfish abundance has steadily declined, principally due to overfishing. This has increased concerns in the fishing community that the growing seal population may impede fish stock rebuilding efforts. However, current knowledge of harbor seal diets are insufficient to draw firm conclusions regarding seal predation on commercially valuable groundfish.

Methods to combine radiometric and ceilometer measurements were developed to improve both the retrieval accuracies of integrated water vapor and liquid water. The rms difference between the retrieved and radiosonde-measured integrated water vapor was 6% relative to the mean. Compared to radiosondes the temperature profiles retrieved using a linear statistical inversion technique were accurate to 1.28 degree C. However, since the radiometric temperature profiles were no more accurate than profiles obtained from climatology, the surface-based radiometer provided essentially no new information regarding the environmental temperature profiles.

Measurements at offshore locations in water depths greater than 100 m have disclosed current speeds exceeding 25 cm/s at 1 m above the lake floor during winter storms when the lake water is unstratified. Counterclockwise veering of the current velocity vector occurs as the bottom is approached, with the veering being most rapid close to the bottom. Measurements of currents during winter and spring have shown prevailing cyclonic circulation at all water depths. This is true of the other deep Great Lakes as well. Mass conservation calculations with the current meter data yield upwelling velocities on the order of 1 m/day in the center of the lake during winter. Water temperature data have been obtained from thermistor strings attached to meteorological buoys moored in the center of the lake by the National Data Buoy Center, Bay St. Louis, Mississippi. Simulations of the temperature data with four different one-dimensional mixed layer models were all premature in timing the onset of stratification. Additional simulations of the temperature data were made with a constant upwelling velocity imposed through late spring. Results of the new simulations were significantly improved over those neglecting upwelling. These results emphasize the importance of Ekman pumping in retarding the start of stratification in large lake basins.

These sites, generally removed from the effects of local pollution sources, show characteristics that typify broad geographical regions. At Barrow, AK; Mauna Loa, HI; American Samoa; and South Pole, data records of 15-20 years show trends that in all cases are a function of season. This dependence on season is important in understanding the causes of the long-term changes. At Barrow, the summer (July, August, September) increase of 1.7% per year is probably indicative of photochemical production. At South Pole, on the other hand, the summer (December, January, February) decrease is related to photochemical losses and enhanced transport from the coast of Antarctica. At all the sites there is a pronounced seasonal variation. In the Southern Hemisphere (SH), all locations which run from 14 to 90 degree S show a winter (July-August) maximum and summer minimum. In the Northern Hemisphere (NH) most of the sites show a spring maximum and autumn minimum. At Barrow (70 degree N) and Barbados (14 degree ), however, the maxima occur during the winter, but for very different reasons. At many of the sites, the transport changes associated with synoptic scale weather patterns dominate the day-to-day variability. This is particularly pronounced at Bermuda and the more tropical sites. JF - Atmospheric Environment AU - Oltmans, S J AU - Levy, H II AD - Clim. Monit. and Diagn.

Our success in finding eddies resulted from placing buoys in high concentrations of walleye pollock (Theragra chalcogramma) larvae. We utilize data from hydrographic surveys, satellite-tracked buoys and moored current meters to describe the eddies. Small (< 25 km diameter) eddies likely transit along the slope of the eastern Bering Sea every 45-60 days. In previous studies such small features were not observed because their size fell within typical separation of hydrographic stations and the weak sea surface temperature gradients are not resolved by satellite-borne infrared imagery.

Historical Lake Ontario outflows could not be used for the study because of anthropogenic effects reflected in the data, the statistically short record length, and autocorrelation of the data. Stochastically generated Great Lakes net basin supplies were used in a Great Lakes hydrologic response model to obtain Lake Ontario levels and outflows. A significant problem was the lack of robustness in the Lake Superior and Lake Ontario regulation plans during simulations with extreme water supplies. The regulation plans were modified consistent with the International Joint Commission's regulation criteria and past operational actions to give reasonable results under these conditions. The simulated Lake Ontario levels and flows had a greater range than those resulting from historical water supplies. The maximum simulated Lake Ontario quarter-monthly level was 76.41 m (IGLD 55), and the maximum simulated quarter-monthly outflow was 14,160 m super(3)/s. The maximum-flow limitation of Lake Ontario's regulation plan, 8,780 m super(3)/s, was exceeded 0.27% of the time. The upper lake-level regulation limit, 75.22 m, was exceeded 0.15% of the time. It was found that some of the regulation criteria cannot be met simultaneously under extreme conditions. Historical water supplies, the current standard for the design and evaluation of modifications to the operational regulation plans, should no longer be the sole test of the plans.

Most eggs were found below 150 m to near bottom ( similar to 300 m) but progressively shallower later in the season. Eggs in middle stages of development were found at shallower depths than were younger or older eggs. The vertical distribution of eggs was positively related to observed differences in seawater temperature but showed no relationship to density. Larvae hatch at incubation depth and quickly rise to the upper 50 m of the water column where they remain during larval development. Larger larvae ( similar to 7-10 mm standard length [SL]) undergo limited diel vertical migration within the upper 50 m. They are deepest during the day, shallowest at dusk, slightly deeper at night, and even deeper at dawn. Their mean depths of occurrence were between 21 and 37 m at all times. At these depths, prey (copepod nauplii) generally were at densities sufficient for larval pollock growth as determined in laboratory studies. Pronounced thermoclines and pycnoclines were present in the part of the water column inhabited by the larvae in late May. Larvae appear to remain below the upper mixed layer during periods of increased turbulence, but at depths during daytime where light was sufficient for feeding and where prey densities were adequate.

This paper establishes a spatial framework for the analysis of water quality behavior in the Florida Keys National Marine Sanctuary. It defines subareas as based upon the variability of circulation behavior and its affect on water quality. The spatial domains are suggested for the aggregation and analysis of data as affected by the circulation characteristics of the subarea for both strategic and tactical issues. The framework recognizes nine unique circulation regimes as based upon our current understanding of the circulation dynamics within the sanctuary and its surrounding waters. Application of the framework is viewed as part of an interative process as ongoing research and monitoring provide the basis for its refinement and use in the development of area specific water quality management strategies.

As in most other vertebrates, this type of high intensity activity in fish is fueled anaerobically. In the early stages of activity energy (as ATP) is derived from the breakdown of high energy phosphates stores, which in vertebrates is phosphocreatine (PCr). Once PCr stores are depleted (within 15 seconds), ATP is derived from the anaerobic breakdown of glycogen. Associated with the breakdown of muscle glycogen and hydrolysis of ATP is an accumulation of lactate and H super(+); the latter resulting in a reduction in intracellular pH (pHi) by as much as 0.4 pH units. Fatigue appears to set in once energy reserves have been depleted, as in exhausted fish, muscle levels of glycogen, ATP and PCr are often below the limits of detection. In the more active fish species, such as salmonids, some of the lactate and H super(+) produced leaks out of the muscle into the blood space, resulting in blood lactate levels of 15-20 mM and a depression in blood pH by about 0.5 units. The peak blood acidosis occurs immediately after cessation of swimming, while blood lactate levels do not peak until 2-4 hours after exercise. Associated with the metabolic and acid-base disturbances are increases in the circulating levels of the "stress" hormones: epinephrine, norepinephrine and cortisol.

The protein fraction of the diet is responsible for more than 60% of the cost of the diet. Research has, I feel, been misdirected towards reducing feed costs ($/kg feed) through the substitution of less expensive animal and plant proteins for fish meal. Relatively little attention appears to have been paid to improving feed efficiency (kg feed/kg fish produced) which also affects production costs: $/kg feed x kg feed/kg fish produced = $/kg fish produced Inefficient diets lead to additional feed handling, do not allow fish to grow to their potential and contribute to pollution. Factors that contribute to poor feed efficiency are: feed loss, poor digestibility, improper protein/energy ratio, poor amino acid balance and high levels of carbohydrate, fiber and ash.

Forecast variables include the surface water level fluctuation, horizontal and vertical structure of temperature and currents, and turbulence. The system uses meteorological observations, satellite data, and forecasts from numerical weather prediction models as input. Lake circulation and thermal structure are calculated using a three-dimensional hydrodynamic prediction model. Output from the model is used to provide information on the current state of the lake and to predict changes for the next two days. This information is used by scientists, government agencies, commercial operations, and the public for enhancement of commercial and recreational activity, resource management, and hazard avoidance. This paper describes system design, data acquisition and analysis procedures, the hydrodynamic model, and sample model output. The initial implementation of the system provides daily nowcasts of system variables for one lake, Lake Erie. Requirements for implementing actual lake forecasts are discussed.

Altogether, 1,060 fish captured by commercial groundfish and shrimp trawlers between July 1986 and July 1987 were examined. Reproductive events were protracted. Insemination of females occurred from August to December, and fertilization and parturition followed from December through March. Spermatozoa were observed within both vitellogenic and previtellogenic ovaries between July and November. Reproductive events in smaller males and females were delayed relative to those in larger individuals. Females attained 50% maturity at a greater size (36.5 cm total length) and age (8.4 years) than males (29.6 cm total length; 5.1 years). The unimodal development of eggs and larvae indicated one parturition per year. Most age-6, age-7, and age-8 females possessed ovaries in an intermediate "maturing" condition. Histological analysis revealed that most of these females were immature; ovaries showed no evidence of previous spawning, oocytes never developed beyond an early vitellogenic stage, and during months of parturition, many of these females were resorbing their advancing oocytes. Total fecundities ranged from 19,815 to 489,064 oocytes per ovary pair and increased exponentially with increasing fish length, linearly with fish weight, and asymptotically with fish age (6 to 66 years).

Photochemical oxidants in the northeastern United States were simulated for the period 2-17 July 1988, one of the most severe air stagnation episodes in the last decade. In the simulations, biogenic hydrocarbon emissions were adjusted by a factor of 3 to account for the existing range of uncertainty in these emissions. The impact of biogenic emission uncertainties on O sub(3) predictions depended upon the availability of NO sub(x). In most cases, O sub(3) concentrations increased in response to increases in biogenic hydrocarbon emissions. However, in some extremely NO sub(x)-limited areas, increasing the amount of biogenic emissions decreased O sub(3) concentrations. Two control strategies were also examined in the simulations: (1) reduced anthropogenic hydrocarbon emissions, and (2) reduced anthropogenic hydrocarbon and NO sub(x) emissions.

Benthic macrofauna and winter flounder were collected monthly and bimonthly, respectively, from July 1986 through September 1989 at three sites in the Bight apex that are variably influenced by sewage sludge. There were limited changes in winter flounder diets and abundance of dominant benthic macrofaunal species following cessation of sewage sludge disposal. The comparison of volumetric contribution of common prey in flounder stomachs to potential-prey abundance in benthic samples suggested several relationships. These included evidence of preferential predation on the polychaete Pherusa affinis; this selective preference may be associated with its high caloric content as well as with its average high biomass density. Other common prey, primarily polychaetes but including an anthozoan, were also preyed upon in proportions greater than their abundance in the environment. Some moderately abundant potential prey, such as the small near-surface-dwelling mollusc. Nucula proxima and the ribbon worm Cerebratulus lacteus were not commonly preyed upon suggesting they were unavailable as prey or were avoided by winter flounder. Corresponding fluctuations in abundances and predation of the pollution-tolerant polychaete Capitella sp. and the pollution-sensitive amphipod Unciola irrorata suggested a proportional consumption relationship in association with sludge disposal and its cessation.

Catch data from six multispecies ground-fish assessment surveys conducted at three-year intervals (1977-92) by the National Marine Fisheries Service's Alaska Fisheries Science Center revealed three assemblages. The first, a deep-water assemblage, consisted of shortspine thornyhead, Sebastolobus alascanus, Pacific ocean perch, Sebastes alutus, darkblotched rockfish, S. crameri, and splitnose rockfish, S. diploproa. Redbanded rockfish, S. babcocki, and rougheye rockfish, S. aleutianus, were closely associated with this group. The second assemblage consisted of canary rockfish, S. pinniger, yellowtail rockfish, S. flavidus, and green-striped rockfish, S. elongatus. This group was most abundant in areas over the middle shelf. The third assemblage, closely associated with the second, consisted of sharpchin, S. zacentrus, rosethorn, S. helvomaculatus, and redstripe, S. proriger, rockfish. While the three assemblages may be of particular interest to ecologists, managers faced with the division of the Sebastes complex management unit into groups that better reflect rockfish cooccurrence may only be able to manage the latter two assemblages as one shelf-rockfish unit.

In separate aquaria, 81 pairs of juveniles covering a wide range of size differences (total lengths differing by 12 to 61 mm) were held and monitored over a 4 day period. Complete consumption, in which a smaller fish was swallowed whole by a larger fish, occurred 11% of the time. In 36% of the pairs, attacks by the larger fish resulted in mortality of the smaller fish. The mouth width:body depth ratio between the larger and smaller fish of a pair differed significantly depending on whether the smaller fish survived, was killed but not consumed, or was ingested whole by the larger fish. Cannibalistic individuals could consume fish close to the maximum size physically possible under gape limitation; at this size the length of the cannibal was approximately 1.7 times the length of the prey. Length-frequency distributions of age-0 pollock in field concentrations suggested that, at least in some geographical areas, potential cannibals and prey commonly co-occur. Unsuccessful predatory attacks by larger individuals may have additional detrimental effects on smaller pollock in natural populations.

The procedure uses a numerical model called Target Transformation Factor Analysis (TTFA) to estimate source emission profiles using ambient trace element air concentration data. The profiles estimated by TTFA are then employed in a Chemical Mass Balance (CMB) source apportionment analysis for an air shed. Other known sources are estimated using source signatures from the literature. The results show that TTFA can be used to provide quantitative estimates of air pollution source profiles for an urban center in China. The number of profiles for unique source types was limited for this data set since emissions from certain types of sources co-varied during each sampling day. Consequently, the CMB analyses that applied the TTFA source profiles needed to be supplemented with standard U.S. EPA source profiles. TTFA can identify source categories of airborne pollution for specific locations, as well as give quantitative data on the composition of the emissions from those source types. The source profiles obtained through a TTFA can be used in a chemical mass balance source apportionment calculation.

Free embryos exhibited positive geotaxis 1 d post hatching, actively swimming through a density gradient to remain in the lower water column. Activity increased with free embryo development and by 7 d post hatching, feeding-ready larvae reversed their vertical orientation, now exhibiting negative geotaxis as they migrated to the upper water column. The results indicate that even at the earliest developmental stages, walleye pollock possess the capability to control vertical distribution. Laboratory results are compared with patterns of vertical distribution observed in the sea. JF - Environmental Biology of Fishes AU - Davis, M W AU - Olla, B L AD - Coop. Inst. Mar. Resour.

A total of 1133 stomachs collected during June-July 1985, January 1988, and July 1988 were examined for contents; only 19.7% contained food items. The diet consisted of pelagic tunicates and other micronektonic animals that are associated with the vertically migrating sonic scattering layer that is advected over the seamount from the adjacent oceanic environment. Peak feeding occurred in the early morning on migrating organisms likely trapped by the expanse of the seamount summit during the morning descent. Newly recruited armorhead had lower feeding rates than older, previously recruited fish. Estimates of daily ration for previously recruited armorhead were 1.17 g (0.26% of body weight) in the summer of 1985 and 12.87 g (2.86% of body weight) in the summer of 1988. Since estimated values for the evacuation coefficient and the duration of the daily feeding period did not differ between sampling periods, the increase in daily ration was due to an increase in feeding rate. The proportion of the diet composed of pelagic tunicates was also higher in 1988. JF - Environmental Biology of Fishes AU - Seki, M P AU - Somerton, DA AD - Honolulu Lab., Southwest Fish. Sci.

The method is based on the size dependence of the movement of the particles in response to an acoustic wave transmitted into the cloud. The density change of the particles induced by this motion is detected with the delta-k lidar technique. A simple, one parameter cloud particle model is used to estimate the performance of the method at ranges from 3 m to 10 km. These performance estimates indicate that the technique may practical for both remote and in-situ sensing of cloud particle size parameters. JF - Atmospheric Research [ATMOS. RES.].

However, hatchery-reared fish may be less equipped behaviourally than wild fish to survive the challenges of the natural environment. One of the major causes of mortality in hatchery-reared Pacific salmon smolts is predation soon after release into the natural environment. Laboratory results on coho, Oncorhynchus kisutch (Walbaum) smolts demonstrated that the potential exists for mitigating deficits in antipredator behaviour. Stress associated with rearing practices, transport and release may render smolts more vulnerable to predation. Behavioural assays were developed to assess predator avoidance capabilities of stressed coho and spring chinook, O. tshawytscha (Walbaum) smolts. Social behaviour and capabilities of hatchery-reared salmon smolts to feed and grow in the wild may suffer from deficits caused by the hatchery environment. Based on laboratory studies, food availability and its influence on the development of behaviours such as aggression and schooling in chum salmon, O. keta (Walbaum) and schooling in walleye pollock, Theragra chalcogramma (Pallas) could potentially mitigate these behavioural deficits. The results of these studies demonstrate that ecologically meaningful quality assurance can be built into population enhancement efforts. JF - Aquaculture Research [AQUACULT. FISH. MANAGE.]. 1994.

With an increase of the globally constant storage capacity, evaporation from the continents rises and runoff falls, because a high storage capacity enhances the ability of the soil to store water from periods of excess for later evaporation during periods of shortage. In addition to this direct effect, atmospheric feedbacks associated with the resulting higher precipitation and lower potential evaporation drive further changes in evaporation and runoff. Most of the changes in evaporation and runoff occur in the tropics and in the northern middle-latitude rain belts. Global evaporation from land increases by about 7 cm for each doubling of storage capacity in the range from less than 1 cm to almost 60 cm. Sensitivity is negligible for capacity above 60 cm. In the tropics and in the extratropics, the increased continental evaporation is split, in approximately equal parts, between increased continental precipitation and decreased convergence of atmospheric water vapor from ocean to land. In the tropics, this partitioning is strongly affected by induced circulation changes, which are themselves forced by changes in latent heating. The increased availability of water at the continental surfaces leads to an intensification of the Hadley circulation and a weakening of the monsoonal circulations. In the northern middle and high latitudes, the increased continental evaporation moistens the atmosphere. This change in humidity of the atmosphere is greater above the continents than above the oceans, and the resulting reduction in the sea-land humidity gradient causes a decreased onshore transport of water vapor by transient eddies. Results established here may have implications for certain problems in global hydrology and climate dynamics, including the effects of water resource development on global precipitation, climatic control of plant rooting characteristics, climatic effects of tropical deforestation, and climate-model errors induced by errors in land-surface hydrologic parameterizations.

AN - 16907979; 3598829 AB - As of this writing, of 1,321 taxa listed on the U.S. federal listing of threatened or endangered organisms, only six have marine or estuarine phases in their life history. None of the six are wholly oceanic. Indecision as to the applicability of the Endangered Species Act (ESA) to wholly oceanic species stems from at least two sources: (1) lack of consensus on population criteria designating special status, and (2) societal and scientific doubt as to whether wholly oceanic species can become endangered. A cursory examination of marine fishes of U.S. territorial waters by regional specialists suggests that at least 39 species are severely depleted and deserve closer examination of their population status to determine eligibility for protection under the ESA. Several regional groupings of the candidate species suggest ecosystem-wide impacts. Where fishing is suspected to be causing large-scale disruptions of fish abundance and fish community relationships, establishment of marine reserves might be a prudent management policy.

Larvae were most abundant at intermediate salinities (i.e. frontal waters) where chlorophyll a and macrozooplankton displacement values were also highest. Using sagittal otolith microstructure, we estimated larval ages ranging from 3-14 d. These ages were used to back calculate spawning dates from 13-24 July and 22-31 August. Mean absolute individual growth rate (length age super(-1)) was 0.47 mm d super(-1), with the least squares linear regression SL = 1.67 + 0.47 AGE (r super(2) = 0.60, Pr > F = 0.0001) representing the best growth curve. Highest growth occurred at intermediate salinities near 31ppt., and temperatures near 29 degree C. There was significant temporal variation in growth, with larvae collected in July growing slower than those from September (0.37 and 0.48 mm d super(-1), respectively). The pooled instantaneous daily mortality rate (Z) of the larvae was estimated to be 0.33 d super(-1) (0.16 d super(-1) in July and 0.41 d super(-1) in September). These results show that significant spawning of yellowfin tuna may occur in the northern Gulf of Mexico in the vicinity of the Mississippi River discharge plume, and suggest that larval growth and survival may be enhanced in the plume frontal waters.

We evaluated the other otoliths, the lapilli and asterisci, as well as the sagittae, as ageing structures and length-at-age estimators in hatchery-reared and wild juveniles (< 50 mm SL). Our otolith mounting and sectioning protocol for preparing sagittal sections required significantly less processing time with no loss in accuracy than the more traditional transverse sectioning reported in the literature. Increments in asterisci were clearly visible from the primordium to the otolith margin, whereas the nuclear region of sagittae and lapilli were more opaque and prevented detection of all rings. Asterisci were not present at hatching, but on average from six days later, therefore the addition of a constant (6 days) to the ring counts of asterisci resulted in this otolith providing more accurate ages then sagittae or lapilli. According to coefficients of determination (r super(2)) generated from the relation between fish length and otolith diameter, the sagitta, asteriscus, and lapillus predict fish length in descending order. However, because inner rings on sagittae were usually undetectable, lengths at ages cannot accurately be predicted. All rings are observable in the asteriscus; thus, by using the 6-day adjustment factor accurate length-at-age prediction is possible.

To determine the potential change in exposure brought about by adding uncontaminated food, whole sediment contaminant bioaccumulation by the midge, Chironomus riparius, was determined in the presence and absence of added food. Lake Michigan sediment was dosed with radiolabeled polycyclic aromatic hydrocarbons (PAHs) and/or DDT and trans-chlordane. Three groups of organisms (Feeding Levels I and II plus a control) were exposed in static assays. After two-, four-, seven-, and ten-day exposures, individual larvae were analyzed for contaminant concentration, mass, and total lipid content. After 7 to 10 days, accumulation of pyrene and benzo(a)pyrene was significantly greater with feeding, while larvae exposed to chrysene accumulated significantly less contaminant when fed, compared to controls. No feeding-related differences in accumulation of the two insecticides were observed. Significant differences in larval mass between test animals and controls were observed only with pyrene-dosed sediment. Larval lipid content tended to remain constant throughout the exposures and did not differ between fed and unfed organisms. Thus, it appears that contaminant bioavailability can be altered by the addition of uncontaminated food. However, this phenomenon appears to be compound-specific and not broadly predictable.

Some early results AN - 16900009; 3805603 AB - An experimental coupled ocean-atmosphere model forecast system has been implemented at the National Meteorological Center (NMC) for routine multi-season climate forecasts. The ocean initial conditions for the forecasts are provided by an ocean data assimilation system which uses a basin model of the Pacific Ocean integrated with a four-dimensional variational data assimilation system. Pacific basin ocean reanalyses for the period 1982-1992 provided both the initial conditions and the verification fields for the coupled model forecasts. The coupled model consists of a modified T40 version of NMC's operational medium range forecast model coupled to a Pacific basin ocean general circulation model. Hindcast experiments starting on the first of every month from October 1983 to 1993 have been made to establish the skill of this system in forecasting sea surface temperature variability in the tropical Pacific with lead times of up to several seasons. The system consistently out performs persistence forecasts even at short forecast lead times, and is able to forecast most of the sea surface temperature variability that occurred in the tropical Pacific during 1984 to 1993.

The conventional explanation for this less-than-linear growth is that the diffusion is undergoing a transition from the near-field to the far-field limits of Taylor's equation. An alternate explanation is presented in this paper for surface releases. This explanation assumes that the less-than-linear growth of sigma sub(y) with x is due to the logarithmic wind profile. A simple roughness- and stability-dependent diffusion model based on this explanation is shown to compare well with field measurements of sigma sub(y). In neutral conditions, the model indicates that sigma sub(y) should be proportional to x super(0.86) and z sub(o) super(0.14), where z sub(o) is the roughness length.

AN - 16884122; 3579972 AB - Postincubation differential filtration (PIDF), preincubation differential filtration (Pre-IDF), and track autoradiography (TA) were compared for estimating cell-specific and total photoautotrophic picoplankton production. Experiments were performed in Lakes Michigan and Huron and in the Gulf of Mexico. When Synechococcus dominated the photoautotrophic picoplankton community (>70% of total picoplankton abundance), PIDF estimates of cell-specific and total picoplankton production were similar to 3.0 x (range, 2.0-3.8 x) higher than TA estimates. PreIDF estimates of cell-specific and total picoplankton production, however, were only slightly higher than TA estimates (mean, 1.4 x; range, 1.4-1.5 x). The higher PIDF estimates were attributable to breakage and damage of larger photoautotrophs during postincubation filtration and to retention of this labeled material on the smaller (0.2 mu m) pore-size filter. Results from PIDF experiments must be viewed with caution and previous estimates of picoplankton production, cell-specific or total, based solely on PIDF may need to be re-evaluated.

Aside from storms, winds over the continental shelf in Onslow Bay blew predominantly along-shore with velocities approaching 14 m/s during February and March 1986, and January and February 1989. Water masses and currents observed at two current-meter morings, one at mid-shelf and the other on the outer shelf, reflected the onshore (or offshore) advection of interior water in compensation for the offshore (or onshore) advection of wind-driven surface water. Winds and currents reversed direction approximately every 4 to 6 days. The larvae of Atlantic menhaden, Brevoortia tyrannus, spot, Leiostomus xanthurus, and Atlantic croaker, Micropogonias undulatus, were most abundant in 17-19 degree C and 20-21 degree C water of the outer shelf and Gulf Stream fronts. There was little indication of diel vertical migration; larval Atlantic menhaden were most abundant in mid- and surface water, while spot and Atlantic croaker were most abundant in mid- and deep water. Given this distribution, the inferred advective transport larvae was at times onshore, but at other times it was offshore. Within a spawning season, the prevalence of either reciprocation could determine the number of larvae that reach coastal inlets.

Atlantic menhaden appear to spawn in a relatively less-predictable environment. Compared with gulf menhaden, Atlantic menhaden are older at the onset of sexual maturity and have a longer reproductive span, as well as a longer spawning period. Atlantic menhaden produce larger eggs, and their larvae are larger at hatching and younger and larger at first feeding; the larvae appear to grow faster but they are relatively smaller than gulf menhaden at their first metamorphosis. Heavy exploitation of Atlantic menhaden has resulted in a truncation of the age structure, contraction of their spawning range, a reduction in lifetime fecundity, and possibly modifications of the egg size distribution. Thus, the risk of reproductive failure may have increased because spawning now takes place over narrower geographic and temporal ranges.

These were combined with monthly average surface observations and used in a surface energy balance model to estimate monthly mean evapotranspiration at each site. The modeled evapotranspiration and surface energy fluxes are reasonable. The nature of the surface energy balance model is such that it can be solved with satellite measurements and numerical weather forecast model output alone. This suggests that large-scale evapotranspiration climatologies can be made without in situ observations. JF - Journal of Climate AU - Tarpley, J D AD - Satellite Res.

From July through September 1993, an experimental observational product to identify convective activity within 30 n mi of six airports from southern Virginia to Delaware was transmitted three times each hour to personnel at Weather Service Offices and Center Weather Service Units and to the meteorologists and flight dispatchers of five major air carriers. This user-oriented evaluation and the associated statistical analysis has provided important feedback to assess the utility of the product as a supplement to ASOS. Integration of information from several products generated by the new Doppler radar at Sterling with lightning network data is being pursued for the second phase of the project. The National Weather Service will determine the viability of this approach to generate products to routinely supplement the information provided by ASOS on either a national or a local basis.

Current knowledge of toxicant exposure and associated biological effects in marine fish from this region will be reviewed and used to evaluate how conditions have changed since intensive sampling began in the 1970s. Also discussed are possible relationships between toxicant-associated disease in individual fish and changes in fish abundance. Finally, on the basis of current evidence the authors will attempt to provide some recommendations as to those types of impact which appear to be the most serious and are particularly in need of attention in future research and monitoring studies in the US/Canada transboundary region.

At all other times the EPR was nearly zero. Each pulse in egg production initiated a distinct cohort. Survivorship from egg to adult was low: 3% for the first cohort and 0.8% for the second. The third cohort did not reach maturity. Mortality was highest in the egg stage - only 10% of the eggs produced survived to first nauplius. Rates of egg mortality were positively correlated with clearance rates of T. longicornis, suggesting cannibalism as a cause of high mortality. However, the clearance rates required would be similar to 34-fold too high, suggesting a different density-dependent factor, such as disease, viruses, ecto-parasitism or consumption by dinoflagellates. Advection and resting egg production do not appear to explain high rates of egg loss.

In so doing, they sample from a variety of production and trade arrangements. Consequently, numerous arrangements may co-exist, perhaps for extended periods. An important dimension of such arrangements is their duration. Consider, for example, a coastal state that seeks to uncover a latent comparative advantage in fishing and, thus, forms a co-operative fishing arrangement with a foreign partner through which virtually all fishing decisions are made by that partner under a long term contractual arrangement. The planned life of that arrangement will influence the extent to which the potential yield of the resource is husbanded by the foreign partner. This, in turn, will determine the long term success with which the coastal country develops its comparative advantage in fishing. As a consequence, the terms of co-operative fishing contracts may be designed to address equity issues. These are different from, but not necessarily independent of, efficiency issues. This is particularly true when partners discount the future at different rates. It is important for the analyst to be aware of these efficiency and equity issues and how they relate to each other.

Development was divided into 21 stages. A piecewise regression model with midpoints of each stage describes the relation between time to each stage of development and temperature. Preserved eggs of each stage are described, illustrated, and photographed. Midpoint of hatch was 393 hours at 3.8 degree C, 303 hours at 5.7 degree C, and 234 hours at 7.7 degree C. Mean length of larvae at hatch increased linearly with temperature. We compared rate of development, time to 50% hatch, and morphological development with other studies of walleye pollock eggs. Rate of development and time to 50% hatch were similar among populations of eastern North Pacific walleye pollock. Western North Pacific walleye pollock required longer incubation times than eastern North Pacific walleye pollock. Morphological development of Shelikof Strait eggs differs from development of western North Pacific walleye pollock eggs: optic vesicles, myomeres, eye lenses, heart, and otic capsules appear earlier than in Shelikof Strait eggs, and eye pigment appears later. The differences in development may be exacerbated by the condition of the eggs in which they were examined (e.g. preserved vs. live). Developmental differences between stocks are discussed with the conclusion that model components for egg mortality and spawning biomass must be based on specimens collected in the area of interest.

The model is a general circulation model of the coupled ocean-atmosphere-land surface system, with a global computational domain, smoothed geography, and seasonal variation of insolation. The simulated increase of sea-surface temperature is very slow in the northern North Atlantic and the Circumpolar Ocean of the Southern Hemisphere where the vertical mixing of water penetrates very deeply and the rate of deep water formation is relatively fast. Extending this work, we investigated the transient responses of the coupled model to the doubling and quadrupling of atmospheric CO sub(2), over the period of several centuries. During the entire 500-yr period of the experiment, the global mean surface air temperature increases almost 3.5 degree C when CO sub(2) is doubled, and 7 degree C when it is quadrupled. In the latter experiment, the thermal structure and dynamics of the model oceans undergo drastic changes, such as cessation of the thermohaline circulation in most of the model oceans, and substantial deepening of the thermocline, especially in the North Atlantic. These changes prevent the ventilation of the deeper layer of the oceans and, if they occurred in reality, could have a profound impact on the carbon cycle and biogeochemistry of the coupled ocean-atmosphere system.

Eighty-six percent of the 78 seals' stomachs examined contained fish. Other prey taxon groups, in decreasing order of their percentages of occurrence, were crabs (73%), clams (55%), snails (47%), amphipods (32%), shrimp (18%), mysids (13%), marine worms (13%) and cephalopods (4%). The most frequently occurring prey species were capelin, Mallotus villosus (82%); codfishes, Gadidae (64%); narrow snow crab, Chionoecetes opilio (63%); eelpouts, Lycodes spp. (56%); longsnout prickleback, Lumpenella longirostris (49%); nutshell clams, Nuculana sp. (42%); and moon snails, Polinices sp. (27%). Seventy-seven percent of the seals examined had consumed prey from three or more different taxon groups. We identified seven food items not previously reported as prey of the bearded seal in the Bering Sea. No differences were detected between the diets of males and females and between adults and juveniles, indicating no apparent segregation of foraging by sex or age. Bearded seals in the St. Matthew Island region of the Bering Sea forage in a manner similar to their conspecifics in other areas where fish constitute a major portion of their diet. Prey selection is probably dependent on availability, and diet may be highly diversified even within a relatively small area during a short period of time. Variety in prey consumption exemplifies the ability of the bearded seal to forage in the seasonally changing habitat associated with the advance and retreat of the ice front.

To achieve the required spatial coverage, the GPCP uses simple rainfall estimates derived from IR and microwave satellite observations. In this paper, we describe the GPCP and its first Algorithm Intercomparison Project (AIP/1), which compared a variety of rainfall estimates derived from Geostationary Meteorological Satellite visible and IR observations and Special Sensor Microwave/Imager microwave observations with rainfall derived from a combination of radar and raingage data over the Japanese islands and the adjacent ocean regions during the June and mid-July through mid-August periods of 1989. To investigate potential improvements in the use of satellite IR data for the estimation of large-scale rainfall for the GPCP, the relationship between rainfall and the fractional coverage of cold clouds in the AIP/1 dataset is examined. Linear regressions between fractional coverage and rainfall are analyzed for a number of latitude-longitude areas and for a range of averaging times. The results show distinct differences in the character of the relationship for different portions of the area. In general, to the south and east of the mountainous axis of Japan, rainfall and fractional coverage are highly correlated for thresholds colder than 245 K, and correlations can be increased by averaging in space and in time up to the dominant period of the precipitation events. To the north and west of the axis, the correlations between rainfall and fractional coverage, while generally smaller for all scales, are highest for thresholds warmer than 245 K. The proportional coefficients relating rainfall to fractional coverage at cold thresholds, however, differ greatly between the two periods and both differ significantly from those found for the GARP (Global Atmospheric Research Program) Atlantic Tropical Experiment. These results suggest that the simple IR-based estimation technique currently used in the GPCP can be used to estimate rainfall for global tropical and subtropical areas, provided that a method for adjusting the proportional coefficient for varying areas and seasons can be determined.

In addition to the standard integration in which the atmospheric concentration of carbon dioxide remains unchanged, two integrations are conducted. In one integration, the CO sub(2) concentration increases by 1%/yr (compounded) until it reaches four times the initial value at the 140th year and remains unchanged thereafter. In another integration, the CO sub(2) concentration also increases at the rate of 1%/yr until it reaches twice the initial value at the 70th year and remains unchanged thereafter. During the 500-year period of the doubling and quadrupling experiments, the global mean surface air temperature increases by about 3.5 degree C and 7 degree C, respectively. The rise of sea level due to the thermal expansion of sea water is about 1 and 1.8 m, respectively, and could be much larger if the contribution of meltwater from continental ice sheets were included. It is speculated that the two experiments described above provide a probable range of future climate change. JF - Journal of Climate AU - Manabe, S AU - Stouffer, R J AD - Geophys. Fluid Dyn.

The larval density in nighttime quantitative samples was calculated and ages determined from otolith microstructure. Back-calculated birthdates and larval abundance data were used to estimate the relative contribution of weekly age cohorts to seasonal recruitment of larvae. Summaries of these data were measures of the spawning distributions. Larvae were recruited to the estuary from mid-November through April, with about 86% collected during February-April. In all years, age and size of larvae increased linearly throughout recruitment until the end of March and then declined. The mean age of recruited larvae over all years was 61 days and the mean standard length was 24.6 mm. Atlantic menhaden spawning season was protracted, lasting 4-6 months. In every spawning season, a dominant birthweek mode in either December or January contributed from 25-43% of the total recruits. More than 76% of all spawning occurred in the December-January period. Individual birthweek cohorts recruited to the estuary over periods from one week to several months. Cohorts that usually contributed the greatest number of individuals to estuarine recruitment usually recruited over longer periods. Atlantic menhaden have apparently selected a spawning season and location that ensures transport of larvae across the southeast United States continental shelf and arrival of most larvae during a time when conditions are conducive to optimal survival in the estuary.

This paper reviews the logistic production model, starting with the basic differential equation and continuing with a description of the model development without the equilibrium assumption. It then describes several extensions, including "tuning" the model to a biomass index; partitioning fishing mortality by gear, time, or area; and making projections. Computation of confidence intervals on quantities of interest (e.g. maximum sustainable yield (MSY), effort at MSY, level of stock biomass relative to the optimum level) can be done through boot-strapping, and the bootstrap can also be used to construct nonparametric tests of hypotheses about changes in catchability. To fit the model, an algorithm that uses a forward solution of the population equations can be implemented on a small computer. An example of the utility of surplus-production models (illustrating several of these extensions) is given. The example is loosely based on swordfish (Xiphias gladius) in the North Atlantic Ocean, but is not intended to describe the actual status of that stock.

By fitting a fish movement model to the tag data, we were able to estimate mortality and movement parameters (including diffusivity), parameters of a function that models FAD attraction, and a separate parameter of island attraction. Diffusivity was high enough to effectively distribute fish throughout the island archipelago (approximately 150 000 km super(2)) within a few months. Estimates of FAD parameters indicate that the presence of up to four or five FADs in an area approximately 50 x 50 km can reduce the propensity for skipjack to leave that area by approximately 50%, but that deploying additional FADs in such an area does not significantly increase their effectiveness in holding skipjack. Estimates of the island attraction parameter imply that the propensity of skipjack for movement away from the archipelago is less than half the propensity for movement within it.

Describing the uncertainty can be important in allowing managers to weigh the benefits and losses of different management strategies and to allay concerns about the effects of process, measurement, and model errors on the scientific advice, even if a formal decision theoretic risk analysis has not been carried out. The four general steps in analyzing uncertainty and assessing risk are estimation of the uncertainty in the assessment of current stock status due to measurement error, evaluation of the impacts of potential model errors on the assessment, stochastic projections incorporating estimation error and process errors to investigate the impacts of different management options, and assessment of risk using simple utility functions. At least one of these steps has been included in assessment analyses of about 20 major U.S. fisheries. All of these steps have been incorporated in the scientific advice on a few fisheries to date and should be attempted whenever possible to improve the information available to fishery managers.

We speculate that iodine chemistry in combination with trends in anthropogenic chlorine and bromine may also be a factor in determining the widespread current depletion of lower stratospheric ozone. We also speculate on a related role for iodine in the sudden springtime surface ozone loss observed in the Arctic. JF - Journal of Geophysical Research. D.

A previous study evaluated morphological variation in skull morphology, but now specimens are available for a greater portion of the range. Also, corrections have been made in data and an assessment has been made evaluating repeatability of character measurements. We reassessed geographic variation in 30 cranial features (26 morphometric measures and 4 tooth counts) based on 611 museum specimens. All characters except two tooth counts showed statistically significant geographic variation, while 21 of the 30 characters exhibited significant sexual dimorphism. Males were larger in most characters; females were larger in some length measurements involving the rostrum and ramus. As in previous analyses, inshore S. attenuata were found to be very distinctive, so subsequent analyses focused on offshore spotted dolphins from 29 5 degree -latitude-longitude-blocks. Mantel tests and matrix correlations for 19 of the 30 features demonstrated significant "regional patterning," whereas 22 of the characters were shown to have "local patterning." Principal-components, canonical-varieties, and cluster (UPGMA and function-point) analyses also were employed to assess geographic variation. In the eastern portion of the range, the subdivision between northern and southern offshore S. attenuata found in the previous investigation was confirmed. In general, blocks to the west (including one encompassing part of the Hawaiian Islands) were more like the southern blocks than those of the northeast. Morphological patterns were similar to those found in a number of environmental variables, particularly water depth, solar insolation (January), sea surface temperature (January and July), surface salinity, and thermocline depth (winter and summer). Present management units are inconsistent with the pattern of cranial variation; spotted dolphins from west of lat. 120 degree W probably should not be pooled with those to the east, as they show closer affinity with the southern offshore unit. In addition, the boundary between the northern and southern units should probably be moved north to about Lat. 5 degree N.

The procedure for calculating the applicable reactive uptake coefficients using laboratory-measured parameters is developed, the necessary laboratory-measured quantities are discussed, and a set of equations for use in models are presented. This approach is demonstrated to be essential for obtaining uptake coefficients for the HOCl+HCl and ClONO sub(2)+HCl reactions applicable to the stratosphere. The measured uptake coefficients for N sub(2)O sub(5)+H sub(2)O and ClONO sub(2)+H sub(2)O as well as those for other heterogeneous reactions are discussed in the context of this model. Substantial direct chlorine activation and consequent ozone destruction is shown to occur due to heterogeneous reactions involving HCl for volcanically perturbed aerosol conditions at high latitudes. Smaller but significant chlorine activation also is predicted for background aerosol loadings at extreme high latitudes, suggesting chlorine activation can occur on background sulfuric acid aerosol in these regions. The coupling between homogeneous and heterogeneous chemistry is shown to lead to important changes in the concentrations of various reactive species. JF - Journal of Geophysical Research. D.

The function is used to develop a model in which both gamma and the natural mortality rate M are formally indeterminate and in which the coming year's catch limit can be viewed as a response function of either estimated gamma or estimated M. Decision theory is then used to derive the optimal catch. The optimal catch is shown to increase with the degree of uncertainty surrounding M, although this conclusion may depend on the short managerial time frame assumed. Three "suboptimal" strategies are also considered: (1) setting catch at the level corresponding to the expected value of M, (2) setting catch at the minimum of the response function, and (3) setting catch at the level corresponding to gamma = 0. The first suboptimal strategy never results in a catch greater than the optimum and always results in a lower expected loss than the second. The performance of the third strategy (relative to the others) depends on parameter values. JF - Canadian Journal of Fisheries and Aquatic Sciences AU - Thompson, G G AD - U.S. Dep.

In 1986, a model evaluation showed that the RELMAP overestimated total sulfur wet deposition for the warm seasons by 25-35%, partly due to subgrid-scale variability in the observed precipitation fields. Refinement of the model grid to fully resolve the precipitation observation network would increase the computational requirements of the model to unacceptable levels. Instead, a new parameterization for the wet removal fraction was implemented in hopes of reducing the model's sensitivity to precipitation variability. The effects of observed sub-grid-scale precipitation variability on SO sub(2) and SO sub(4) super(2-) wet removal in the original and updated RELMAP have been isolated and analysed.

I: Research vessel surveys, 1986-1990 AN - 16827537; 3563820 AB - We used canonical correspondence analysis (CCA), an eigenvector ordination technique that includes direct gradient analysis, to investigate habitat use by spotted, Stenella attenuata, spinner, S. longirostris, striped, S. coeruleoalba, and common, Delphinis delphis, dolphins in the eastern tropical Pacific during 1986-1990. Data were collected during annual research vessel cruises conducted in August-November of each year. Environmental variables included in the analyses were surface temperature, salinity, sigma-t, and chlorophyll, and thermocline depth and thickness. The dominant pattern in the species-environment relationship (1st canonical axis) separated common dolphins from spotted and spinner dolphins, based on their associations with cool upwelling habitat and warm tropical habitat, respectively. The second axis separated whitebelly spinners from eastern spinner dolphins. Both occurred in tropical water, but were separated primarily by thermocline topography. The species-environment correlations were 0.67 on the first axis, 0.42 on the second. Overall, the environmental data explained 15% of the variance in the species data. For individual school types this ranged from 36% for common dolphins to 6% for striped dolphins. Interannual variability in the species data was small but was judged significant by a Monte Carlo randomization test.

Declines in density occurred mainly at sites in the southeastern portion of the lake where unionids were highly infested with D. polymorpha. Unionid densities at highly infested sites declined from 2.4/m super(2) in 1986, to 1.8/m super(2) in 1990, and to 0/m super(2) in 1992. While the mean number of D. polymorpha per unionid was < 1 at these lightly infested sites in 1990, it increased to 35 by 1992. Given this relatively slow increase in D. polymorpha per unionid in this portion of the lake, continued monitoring of populations should provide a better understanding of the relationship between the extent of infestations and unionid mortality.

More than 10,000 juvenile salmon were caught in 252 purse-seine sets during August 1983, July 1984, and August 1984. Distribution was patchy; juvenile salmon were highly aggregated, rather than dispersed randomly. Distribution and size of pink salmon (O. gorbuscha), sockeye salmon (O. nerka), and chum salmon (O. keta) were similar but differed from coho salmon (O. kisutch). Chinook salmon (O. tshawytscha) were excluded from most analyses because few were caught. Sizes were consistent with the concept that juvenile salmon in more northern and seaward locations had been at sea longer than those in more southern and inshore locations. Juvenile salmon migration up the Pacific coast did not peak in abundance off Southeast Alaska until August; movement from inside to outside waters was not complete by the end of August. The migration band of juvenile salmon in outside waters of Southeast Alaska extended beyond the continental shelf to at least 74 km offshore, twice the distance previously reported.

The break-and-burn method of age determination is difficult to apply to sablefish. Therefore, we applied a relatively new method of fish age validation, using the disequilibrium of Pb-210/Ra-226 in the otoliths. This method of validation complements previous methods which used oxytetracycline (OTC) marking to validate incremental growth in sablefish otoliths. The Pb-210/Ra-226 disequilibria generally confirmed the ageing criteria used to interpret the otolith's burnt cross-section.

These were made with ground-based and airborne weather radars at nearly vertical incidence. A sharp decrease of | sub( rho hv)(0)| occurs at the bright band bottom, and is attributed to a varying mixture of hydrometeors with diverse shape, size, and thermodynamic phase. The largest contribution to decorrelation seems to come from wet aggregates; this is substantiated by consideration of two simple models. One consists of randomly oriented wet prolate spheroids, and the other considers an ensemble of distorted spheres. Prolates with axis ratios of 3 or distorted spheres with rms roughness equal to 15% of the diameter decrease the correlation to 0.8 at S band. At Ku band and for the size range encountered in the bright band, the decrease is a function of equivalent diameter because scattering is in the Mie regime. | sub( rho hv)(0)| measurement at 13.8 GHz and from the aircraft are the first ever. Also, differential phase and differential reflectivity at a 10 degree off nadir are the first of its kind. These last two variables showed a distinct signature in the bright band. This is significant because it might lead to applications on airborne or spaceborne platforms.

AN - 16805578; 3555760 AB - Hydrofluorocarbons, many of which contain a CF sub(3) group, are one of the major substitutes for the chlorofluorocarbons and halons that are being phased out because they contribute to stratospheric ozone depletion. It is critical to ensure that CF sub(3) groups do not cause significant ozone depletion. The rate coefficients for the key reactions that determine the efficiency of the CF sub(3) radical as a catalyst for ozone loss in the stratosphere have been measured and used in a model to calculate the possible depletion of ozone. From these results, it is concluded that the ozone depletion potentials related to the presence of the CF sub(3) group in hydrofluorocarbons are negligibly small.

Most larvae were found in the upper 45 m of the water column throughout the diel period but were concentrated in higher densities near the surface (0-15 m) n daylight hours and at greater depths at night. Four of the five dominant taxa examined in detail showed significantly greater weighted mean depths during the night than during the day. This pattern was the opposite to that previously reported for the numerically dominant taxa (Theragra chalcogramma) in this area. Since there was no clear relation between the diel vertical distribution of these taxa and the vertical distribution of water temperature and density or copepod nauplii prey, we hypothesize that this reverse migration is either a strategy to minimize spatial overlap with predators that follow a normal diel migration pattern or one to optimize light levels for feeding.

Effects on abundances estimated from tuna vessel sightings, 1975-1990 AN - 16804201; 3551974 AB - The results of a canonical correspondence analysis (CCA) of data from research vessel surveys of the eastern tropical Pacific were applied to time series of estimated dolphin abundances from tuna vessel sightings. The research vessel survey data consisted of daily dolphin school sightings and concurrent environmental variables for August-November of 1986 through 1990. Seasonal field of habitat quality for 1975-90 were calculated from historical bathythermograph data by using the CCA ordination results. For spotted (Stenella attenuata) and eastern spinner (S. logirostris orientalis) dolphins, annual abundance estimates or interannual changes in those estimates are significantly correlated with habitat quality. This effect is at least partly due to expansion of high quality habitat beyond the geographic ranges assumed for the abundance estimate. We discuss ways that environmental data could be used to reduce error in dolphin abundance estimates. JF - Fishery Bulletin AU - Fiedler, P C AU - Reilly, S B AD - Southwest Fish. Sci.

Sampling extended from Cape Sable, Nova Scotia to Cape Hatteras, North Carolina during eight surveys from June 1984 to April 1985. Twenty-four taxa were analyzed for evidence of extrusion by comparing the standardized abundances between the two plankton nets. The mean estimated abundance under 10 m super(2) of sea surface for all taxa combined was 54% higher in the 0.333 mm net. The difference in catches between nets occurred primarily in the 2 to 5 mm length range, indicating that the smaller larvae were extruded through the 0.505 mm mesh net.

Fur seals were collected from August to October of 1981, 1982, and 1985. Juvenile walleye pollock (Theragra chalcogramma) and gonatid squid were the primary prey. Pacific herring (Clupea pallasi) and capelin (Mallotus villosus), considered important fur seal prey in previous reports, were absent from the diet. Prey species and size varied among years and between nearshore and pelagic sample locations. Interannual variation in the importance of pollock in the diet of fur seals was positively related to year-class strength of pollock. Midwater (n=23) and bottom (n=116) trawls were conducted at the location of fur seal collections to determine availability of fish and squid relative to prey species eaten by fur seals. The species and size composition of prey taken by fur seals was similar to midwater trawl collections, but differed from bottom trawl catches. Contrary to earlier conclusions that northern fur seals are opportunistic in their feeding habits, we conclude that fur seals are size-selective midwater feeders during the summer and fall in the eastern Bering Sea.

Methods of reporting and comparing proximate composition are discussed. Examination of measurements presented in a number of published papers, using allometric analysis, indicates that comparison of proximate compositions on a dry weight basis and failure to include fish size as a covariate have, in many cases, led to erroneous conclusions concerning the effects of environmental and dietary factors on the proximate composition of cultured fishes. Available evidence indicates that the protein content of growing salmonids is determined solely by fish size (is endogenously controlled), that lipid level is effected by both endogenous and exogenous factors, that ash content is homeostatically controlled, and that whole body moisture is inversely related to body lipid. The implications of the present findings to nutrition studies and the potential for modification of carcass composition in cultured fish are discussed.

Specimens were captured from the western, central, and eastern North Pacific between approximately lat. 38 degree N and 47 degree N by driftnet fishing, trawling, and jigging in the summers of 1990 and 1991. Results suggest that increments were deposited at a rate of one per day. Both sexes live approximately one year; males mature at smaller sizes and younger ages than females. Exponential growth models suggest that growth in length was similar for males and females (0.80% ML/day) in the central North Pacific, while growth in weight was higher for females (1.90% WT/day) than males (1.40% WT/day). Females in the western North Pacific exhibited faster growth rates than individuals from the central North Pacific. O. borealijaponica were estimated to have hatched year round based on back calculation of statolith increments from the time of capture. Post-recruit individuals exploited in the O. borealijaponica jig fishery and Ommastrephes bartramii driftnet fishery typically hatched from late summer to early winter.

There are two identifiable stocks of king mackerel in the Gulf of Mexico: a western stock and an eastern stock. The western stock migrates northward along the Mexico-Texas coast during the spring and early summer from its winter grounds in Mexico (Yucatan Peninsula). This stock has a high frequency of the dipeptidase PEPA-2*a allele. The eastern stock migrates at the same time northward along the eastern coast of the Gulf of Mexico from its winter grounds in south Florida (Gulf of Mexico and Atlantic coast). This stock has a high frequency of the dipeptidase PEPA-2*b allele. Both stocks migrate simultaneously into the northern Gulf of Mexico and mix at varying degrees in the northern summering grounds (Texas to northwest Florida).

Recent studies have documented dense populations on seamounts of the South Atlantic and North Pacific. At Southeast Hancock Seamount, a small guyot in the Central North Pacific, M. muelleri populations are mainly composed of juveniles. Seasonal length frequencies suggest that recruitment at sizes greater than 20 mm standard length (SL) occurs principally in spring and summer months, with growth over summer and fall coincident with decreasing abundances. Mature fish in reproductive condition occur in winter months but do not survive to the following spring; they also may be too few at this small seamount to support annual recruitment. Potential sources of additional recruitment include populations at several larger seamounts in the southern Emperor group and also the large populations around Japan. Advection of eggs and larvae in the Kuroshio Extension may provide recruits for dependent populations at the seamounts. Mean current flow and satellite-tracked drifters suggest a transit time of 100-200 days from the coast of Japan to the region of the seamounts; estimates of age at length suggest that smaller fish have similar ages at recruitment. Gill-raker counts, however, differ between Japanese and seamount populations. We suggest that the southern Emperor Seamount populations serve as the source for replenished annual recruitment to the small population at Southeast Hancock Seamount.

Following removal of 80% of the adult white sucker population, the composition of somatic tissue of adult yellow perch collected from mid-April to mid-July improved, with water content decreasing and fat and caloric contents increasing. In a nearby reference lake, yellow perch proximate composition showed either no change or became less favorable during the same time period. From mid-July to mid-October, somatic tissue composition showed no improvement in Douglas Lake; this is consistent with a previous study showing that feeding rate late in the summer was not significantly different after sucker removal. Gonadal development had a strong influence on the composition of somatic tissues. Immediately following spawning, fat and energy reserves were depleted and the water content of somatic tissues was high. During the summer (May through August), yellow perch stored fat and energy in somatic tissues, and their body water contents decreased in both lakes. Both sexes of yellow perch began gonad development during September and showed concurrent declines in fat and energy content in somatic tissues. Male yellow perch completed gonad development by mid-October, whereas gonadal development in females continued until spawning in late April. Male and female yellow perch showed similar rates of decline in fat and energy content during the winter, even though females were developing gonadal tissue during this time and males were not. Because female yellow perch required additional energy for gonadal development during the winter but showed a rate of somatic energy depletion similar to that of males, it appears that female yellow perch either rely on feeding or use energy-saving behaviors during the winter to supply the additional energy required for gonadal development. The improvement we observed in yellow perch body composition following white sucker removal indicates that fish respond to reductions in competition with qualitative changes in proximate composition as well as with quantitative changes in growth.

VICBAR is compared to the other operational hurricane track forecast models and is shown to perform as well as each of these. VICBAR forecasts are stratified by initial date, intensity, and location to assess the variability of model performance. VICBAR produces the best forecasts for hurricane cases, for cases initiated earliest in the hurricane season, for cases moving the most slowly northward, and for those moving westward. The forecasts with the largest errors are examined to illustrate the limitations of the model and to determine whether these cases can be identified operationally.

Persistent landward and net northward flow characterized the circulation of near-surface waters during the larval periods studied. A mechanism for progressive seaward transport of larvae through ontogeny, as proposed by others, was not apparent. Overall, above- (below-) average year classes were associated with relatively weak (strong) northward transport and, to a lesser degree, strong (weak) landward transport. Based on these analyses and in consideration of the prevailing coastal circulation, we propose that the relative magnitude of C. magister juvenile recruitment and, hence, incoming year class strength, reflects: (1) the proportion of larvae retained within a relatively narrow ( less than or equal to 15 km) and heterogeneous 'coastal landing strip', (2) the availability of suitable substrate within the coastal landing strip at time of settlement and (3) the magnitude of downstream advective losses (export) of larvae from the California-Oregon-Washington coastal system. Based on a consideration of the physics of the California Current system and the larval biology of the species, significant linkage of Dungeness crab populations along the west coast of North America is likely.

Statistics on the number of flashes, location, polarity, peak currents, and multiplicity (number of strokes per flash) are examined in an 18-h period divided into prelandfall and postlandfall categories. Land-based and aircraft lower fuselage radar data are also analyzed to determine the nature of the precipitation in which lightning is detected. Jerry is found to be more electrically active than Hugo, with 691 flashes detected compared with 33 flashes for Hugo. The majority of these flashes, regardless of the polarity, are located in the right front and right rear quadrants of the hurricanes, almost exclusively in outer convective rainbands. One reason for the large difference in the number of flashes between the two storms is the presence of many convective rainbands in Jerry, compared to only a few in Hugo. More than 20% of the flashes in each storm have a positive polarity. Median negative peak currents of the first return strokes are 49 kA in Hugo and 40 kA in Jerry. Median positive peak currents are 65 kA in Hugo and 52 kA in Jerry. The mean multiplicity of the negative flashes is 1.7 in Hugo and 2.6 in Jerry. Twenty percent of the negative flashes detected in Jerry have a multiplicity of 4 or higher.

In addition, possible changes in partitioning with sediment aging and during bioaccumulation assays were examined. Centrifugation with C-18 separation produced the most consistent partition coefficients. Partition coefficients from filtration and centrifugation methods compared favorably with previously published data. Contaminant partitioning did not change during 96-h exposures in bioassays, and partitioning of contaminants in porewater and elutriates did not follow a linear trend with the amount of sediment aging or manipulation. The contaminant partitioning apparently depends on characteristics of the contaminant as well as contaminant-associated media composition.

We compared length data obtained from vertical aerial photographs of 28 schools of striped dolphins from the northern and southern regions of the eastern tropical Pacific and found no significant differences in average length for adult animals ( greater than or equal to 180cm) or for adult females, defined here as dolphins closely accompanied by a calf. Analyses of back-projected birth dates for dolphins greater than or equal to 155cm revealed a broad pulse in reproduction extending from the fall through the spring; however, sample size was inadequate to compare timing of reproduction between the two areas. Striped dolphins measured from aerial photographs were longer on average than those killed incidentally in fishing operations. We found a pattern of segregation by size between schools that is analogous to the separate schools of juveniles and adults that are found in the western Pacific. We hypothesized that the specimen data base may be biased because tuna purseseine fishermen in the eastern tropical Pacific may selectively set on schools composed of younger, smaller dolphins.

Strains of these species that had been induced to tolerate high Cd concentrations were cultured axenically in artificial seawater media with 15, 60, and 60 mg/liter Cd, respectively. Algal diets consisting of strains of these species cultured in Cd-free medium and containing no measurable Cd served as controls. Algal cells were harvested in a nitrogen deficient stationary phase from semi-continuous cultures and analyzed for Cd uptake. Daily feeding rations of the three algal species listed above contained known quantities of Cd: 41.0, 20.2, and 15.2 mu g/bivalve/day, respectively. Daily algal rations were also analyzed for nutritional components (protein, carbohydrate, and lipid), and significant effects of Cd on algal composition were found. Oysters fed cadmium-contaminated P. tricornutum, D. tertiolecta, or a 50/50 mix of these two species exhibited varied responses. Diets including Cd-contaminated D. tertiolecta caused mortality and weight losses of oysters whereas, oysters fed P. tricornutum cultured in Cd showed no significant effect. Clams fed unialgal diets of Cd-contaminated I. galbana, D. tertiolecta, or P. tricornutum did not grow, but mortality was observed only in clams fed Cd-contaminated P. tricornutum. Differences in bivalve responses to the various algal diets may reflect interactions between Cd toxicity and nutritional factors, especially for oysters in which the toxic effects of Cd were more severe when more digestible diets were fed. These results demonstrate detrimental effects of pollutant-contaminated algae upon consumer species' survival and growth, parameters of fundamental importance to population structure.

Updrafts and downdrafts as strong as 24 and 19 m/s, respectively, were found. Mean updrafts and downdrafts were approximately twice as strong as those found in other hurricanes. Updrafts had approximately the same width as downdrafts. The most vigorous updrafts were located in the front quadrants of the storm, and most of the strongest downdrafts were found in the rear quadrants. The downdrafts could not be explained in terms of evaporative or melting cooling, or precipitation drag. Evidence is presented that moist symmetric instability initiated by precipitation loading may have been responsible for the strong downdrafts.

Bioavailability of a sediment-associated contaminant can be defined by the uptake clearance. Uptake clearance is the volume or mass of the source compartment scavenged of contaminant per mass of organism per time. For non-polar organic contaminants, carbon normalization has been suggested as a means of normalizing the relative bioavailability among sediments of differing compositions. To examine this, amphipods, Diporeia spp., were exposed to five Lake Michigan sediments and one soil from Florissant, MO, each spiked with selected polycyclic aromatic hydrocarbon (PAH) and polychlorinated biphenyl (PCB) congeners. The uptake clearances (k sub(s)) were then determined. The PAH congeners were generally less bioavailable, based on k sub(s), than the PCB congeners after accounting for contaminant hydrophobicity. The k sub(s) values generally declined as the fraction of fine particles (<63 mu m) and organic carbon increased among the sediments. Organic carbon normalization reduced the variability among the k sub(s) values to approximately a factor of two among the Lake Michigan sediments, but the Florissant soil was an outlier. The compounds were more bioavailable from the Florissant soil than from the Lake Michigan sediments, and the relative availability increased with increasing contaminant hydrophobicity up to a factor of eight for hexachlorobiphenyl.

We observed no change in pigment content or in a* values after 180 d frozen storage or following a thaw/refreeze cycle compared to fresh fish, even though higher a* values were seen in fillets from fish fed synthetic astaxanthin or canthaxanthin after 90 d frozen storage suggesting that care should be used when interpreting tristimulus color values for grading programs.

Doppler sodars and lidars as well as newly emerging 915-MHz radar wind profiler technology are shown to describe well mean wind and temperature profiles. A number of air quality field research programmes have now deployed these instruments in various combinations in mesoscale experiments. Three studies provide examples for discussion of mean wind and temperature profiles. Unfortunately, many remote sensing instruments have not realized their full potential for measurement of turbulent momentum and heat fluxes as well as mixed-layer depth. A simple four-beam Doppler acoustic system provides a preliminary example of such potential applications. Furthermore, pattern-recognition methods, although subjective in nature, can be applied to time-height cross sections of reflectivity with the data of use in the interpretation of dispersion process in the atmospheric boundary layer.

Furthermore, rather ad hoc assumptions have been made when modeling landfall. The general consensus is that energy supplied primarily through surface fluxes is necessary for tropical cyclone development and maintenance. In the past, rather a priori assumptions have been made such as the elimination of surface sensible and latent heat fluxes over land or the reduction of surface land temperature. By incorporating an improved version of the Geophysical Fluid Dynamics Laboratory (GFDL) tropical cyclone model with diurnal radiation and a bulk subsurface layer with explicit prediction of land temperature, a series of experiments was performed to test the sensitivity of surface boundary conditions to tropical cyclone development and decay at landfall. A triply nested version of the GFDL model was used in an idealized setting in which a tropical disturbance, taken from the incipient stage of Gloria (1985), was superposed on a uniform easterly flow of 5 m s super(-1). A control case was performed for ocean conditions of fixed 302-K SST in which the initial disturbance of about 998 hPa developed to a quasi-steady state of 955 hPa after one day of integration. Using identical atmospheric conditions, a series of experiments was performed in which the underlying land surface was specified with different values of thermal property, roughness, and wetness. By systematically changing the thermal property (i.e., heat capacity and conductivity) of the subsurface from values typical of a mixed-layer ocean to those of land, a progressively weaker tropical system was observed. It was found that the initial disturbance over land failed to intensify below 985 hPa, even when evaporation was specified at the potential rate. The reduction of evaporation over land, caused primarily by the reduction of surface land temperature near the storm core, was responsible for the inability of the tropical disturbance to develop to any large extent. Under land conditions, the known positive feedback between storm surface winds and surface evaporation was severely disrupted. In sensitivity experiments analogous to the all-land cases, a series of landfall simulations were performed in which land conditions were specified for a region of the domain so that a strong mature tropical cyclone similar to the ocean control case encountered land. Again as in the all-land case, the demise of the landfalling storm takes place due to the suppression of the potential evaporation and the associated reduction of surface temperatures beneath the landfalling cyclone. Even when evaporation was prescribed at the potential rate, a realistic rapid filling (36 hPa in 12 h) ensued despite the idealized nature of the simulations. Although not critical for decay, it was found that surface roughness and reduced relative wetness do enhance decay at landfall.

Cultures in the logarithmic and stationary growth phases were each tested in three ways: 1) live cells against live cells; 2) live cells against medium previously used to grow each algal strain; 3) live cells against medium-soluble cellular extracts of each algal strain. In shellfish aquaculture, the most favorable of situations would be to grow algal strains that are nutritious to shellfish and that grow densely. Algae that exhibit allelopathy should be more successful at resisting culture contaminants and therefore would be more dependable to culture for shellfish food. Further, by selecting out of these the strains that exhibit antibiotic abilities, against undesirable and contaminating bacteria, the shellfish cultured should be healthier.

These confrontations are furthered by competition for access to habitat of declining populations. Confrontations are often in inverse relationship to the level of government involved although all are experiencing difficulty. These circumstances, individually and collectively, indicate a need for a national policy on aquaculture. It should reflect the "state-of-the-art" on this topic and contain an appreciation of traditional fishing activities. The policy should provide guidance for siting, design and operation of aquaculture operations and assurances that competing uses are given full and equal consideration. To establish this policy, proponents of aquaculture should network and develop the kills necessary to influence public opinion.

Cultured and wild juvenile oysters from Oyster and Peconic Bays on Long Island, NY, were also collected in July and September. All were examined for mortality, size, and presence of conchiolin in live and dead oysters. A clear relationship was seen between the presence of conchiolin and mortality. The highest prevalence was seen in dead oysters (70-100%), but high levels were also seen in surviving oysters (14-60%). The presence of conchiolin diminished after mortality stopped and calcified lesions which matched shell checks were apparent. Primary shell checks usually measured 15-19 mm, comparable to size at the initial mortality period. Secondary and tertiary shell checks were evident in some older oysters. Conchiolin and healed shell lesions also were found in fresh boxes 70-112 mm in length. Four percent or less of the 1992 natural set examined from oysters in Peconic Bay exhibited conchiolin. No evidence of JOD was seen in any 1993 natural seed examined in September. JF - Journal of Shellfish Research AU - Farley, CA AU - Lewis, E J AD - NOAA/NMFS, Northeast Fish. Sci. Cent., Coop.

Over 50% of seafood harvested from inland waters is from aquaculture, while less than 10% of seafood production from marine waters is of an aquacultural origin. The aquaculture industry continues to grow in the United States at a rate lower than that worldwide. While overall seafood consumption in the U.S. has declined since reaching a peak in 1987, the percent of that consumption contributed by farm-raised seafood product has risen. The National Oceanic and Atmospheric Administration (NOAA) has been involved in aquaculture since the late 1800's. Extensive fishery management responsibilities assumed by the National Marine Fisheries Service (NMFS) led to neglect of commercial aquaculture research. A review of recent policy actions by NOAA and the Department of Commerce show that this decline has been checked. NOAA is now developed an Implementation Plan for Aquaculture which will serve as a planning guide for the next several years. The Implementation Plan will (1) identify opportunities and recommend strategies to strengthen enhancement capabilities, (2) establish criteria for identifying appropriate candidate species for use in commercial and enhancement aquaculture systems, (3) identify opportunities for collaborative system design studies with the private sector or other Federal agencies, (4) identify research parameters for nearshore and offshore culture systems which minimize environmental perturbations, and (5) develop experimental plans to verify the effectiveness of enhancing wild populations with releases of hatchery-reared finfish.

The authigenic-phase glauconite occurs above detection limits only in the core from the hypoxic area. A major increase in glauconite concentration was coincident with the onset ( similar to 1940) of the increased use of commercial fertilizers in the United States. In the same hypoxic-area core, benthic foraminifera species diversity decreases upcore from approximately the turn of the century to the present in a manner concurrent with glauconite and fertilizer increases. A subset of opportunistic benthic foraminifera species, known to become more prominent in stressed environments (i.e., hypoxic), increased upcore from similar to 52% of the total population at core bottom to similar to 90% at core top. These benthic foraminifera population and diversity changes were not apparent in a "control" core outside the area of documented hypoxia. Seaward of the shelf, in the Mississippi Canyon, coincident increases in sediment accumulation rate, percentages of coarse fraction and of organic carbon at core top indicate increased offshelf transport of carbon and other components.

Genetics and biotechnology studies offer additional opportunities for improving desirable characteristics and for investigating heritable and molecular bases of processes including growth, development, survival, and responses to stress, such as pollution and disease. Moreover, in enhancement efforts, there is a need for development of methods to increase the reproductive potential, conserve gene pools, and improve genetic adaptation of species in stressed environments. For example, oysters bred selectively for fast growth at the Milford Laboratory on Long Island Sound are being employed in studies of survival and disease resistance in Maine and New Jersey.

Classification of these isolates to genus or species level was often difficult; application of bifurcating keys using bacterial phenotypic traits frequently produced results that were contradictory to other identification methods. In an attempt to resolve these problems, a database of phenotypic characteristics of known pathogenic species was compiled from the literature. Ninety-six permutations of pairs of computer-aided, numerical-taxonomy programs and clustering techniques contained in the NTSYS-PC software package (Exeter Software, Setauket, New York) were analyzed for their ability to group known organisms in the database into correct phylogenetic groups. The most accurate combinations proved to be K2 or UN5 coefficients clustered with WPGMA or UPGMA. The reliability of the various computer programs wil also be discussed.

While aquaculture promises to play a significant role in international food and nonfood product markets, the role that aquaculture may play in the United States and an international economy is still unfolding. In this presentation an overview of economic and institutional issues that will influence the pattern and rate of development of marine aquaculture in the United States are discussed. Particular emphasis is placed on how these issues may affect the global competitiveness of United States aquaculture products in international markets.

The juvenile softshells set in bottoms mostly from the low tide mark to a distance at least 60 m from shore to depth of at least 1 m; further depths were unexplored. In the Navesink River, densities were high (up to 7,000/m super(2)) nearly everywhere in early July, but declined gradually by about 40% by November, 1993. Densities in the Shrewsbury River were about 2/3 as high. The reduction in densities was not caused by predation, but by many softshells emerging from the bottom and living on the surface for a few weeks before dying. By November, mean sizes of the clams at different sites in the rivers and Raritan Bay ranged from about 15-24 mm. Besides the softshells; oysters, Crassostrea virginica; amethyst gemclams, Gemma gemma; and Atlantic jackknife clams, Ensis directus, also set in unusually high densities. The sets resulted from relatively small spawning stocks of softshells, oysters, and jackknife clams. Setting was also heavy of softshells; oysters; northern quahogs, Mercenaria mercenaria; and bay scallops, Argopecten irradians, in some bays on Long Island and in southern New England.

Studies reported herein evaluate the effects of salinity and selected standard saltwater aquarium medications on transmission and treatment of JOD. Disease transmission to uninfected Horn Point hatchery-reared oysters, mean length 20 mm, was attempted at salinities of 10-26 ppt. Transmission occurred at 20 and 26 ppt, with 60% and 75% cumulative mortalities after 6 weeks exposure. Dead oysters exhibited conchiolinous shell lesions typical of JOD. Mortalities declined with decreased salinity. At 10 ppt, 16% of the oysters died, but no conchiolin was observed. There was no association of a specific bacterium and JOD infections in this study.

M. Flower Hatchery causes no apparent ill effects in juvenile oysters AN - 16735093; 3718536 AB - A Gymnodinium sp. culture was established from an Oyster Bay water sample, taken near the F. M. Flower oyster hatchery on 17 August, 1992. At this time, mortalities from "juvenile oyster disease" were occurring. An experiment was conducted to determine if juvenile oysters exposed to this dinoflagellate exhibited characteristic symptoms of either 1) juvenile oyster disease, ie, conchiolin deposits within the shell, wasting of mantle tissue, and mortality, or 2) degeneration of absorptive cells of the digestive diverticula, as seen in shellfish feeding on certain other dinoflagellates. For the first two weeks, oysters fed Gymno-F filtered actively, but produced abundant pseudofeces; thereafter, normal fecal strands were produced. The other two diets were ingested normally. Shell growth was noted qualitatively in all treatments except the unfed control. After 36 days--approximately the time required for development of juvenile oyster disease symptoms--oysters were sacrificed, observed for abnormal conchiolin deposits, and evaluated histologically. No abnormal conchiolin deposits were found, nor was there any histological evidence of poor health in any fed treatments. Digestive diverticula showed good development in all fed controls, with Gymno-F appearing in slightly better condition than the other fed controls. From these observations we conclude that this isolate of Gymnodinium is not a causative agent of juvenile oyster disease. The refractory period during which oysters produced pseudofeces when fed Gymno-F is consistent with our previous studies of oysters feeding on another dinoflagellate, as is the eventual resumption of normal feeding and growth; this may be related to changes in oyster digestive enzymes.

Phenanthrene was only slightly toxic with 12 plus or minus 3% mortality at the highest sediment dose (0.62 mu mol/g). Failure to attain and maintain toxic residue body burdens, based on a nonpolar narcosis concentration of approximately 6 mu mol/g, accounts for the low mortality. Phenanthrene toxicokinetic parameters were essentially constant among all doses and consistent with previous measures. Sediment concentration was a poor representation of dose for mortality by pyrene. The relative pyrene distribution among the <63- mu m particles increased in the smallest-sized particles at larger doses. An apparent stimulation of pyrene accumulation was observed as a peak in uptake clearance values between sediment concentrations of 0.16 and 0.26 mu mol/g dry sediment. (Uptake clearance is the amount of source scavenged of contaminant per mass of organism per time.) The pyrene particle-size distribution and the variation in kinetics with dose provide a partial explanation for the poor representation of dose by the sediment concentration. The pyrene body burdens provided a good dose response yielding LD50 values of 6.3 (4.6-41.7, 95% C.I.) and 9.4 (7.9-54.2) mu mol/g for two experiments. These values are consistent with the residue concentrations for 50% mortality by a nonpolar narcosis mechanism. Comparing the experimental and predicted equilibrium partitioning-based sediment concentrations for 50% mortality, the equilibrium prediction overestimates the toxic pyrene sediment concentration by approximately a factor of ten. Diporeia behavior, differential particle-size distribution, and kinetic limitations appear as likely reasons for the variation between calculated and observed concentrations required to produce mortality.

Three habitat types (channel edges, willow edges, and debris pools) were sampled at two downstream sites (lower river) and at two upstream sites (upper river) biweekly from May to September and once in November 1989. For most species, fry (age 0) most often used channel edges with little cover, whereas parr (age greater than or equal to 1) almost exclusively occupied willow edges and debris pools. Within the same habitat types, densities were significantly greater for most species and life-history stages in the upper than in the lower river; steelhead parr, with densities similar in like habitats in the upper and lower river, were a notable exception. Peak fry densities (fish/100 m super(2)) were 2,331 coho, 155 steelhead, and 14 sockeye, whereas peak parr densities were 281 coho, 82 steelhead, and 44 Dolly Varden. Mean length of fry and parr of all species was greater in the lower river than in the upper river. With baseline information from this study, fisheries managers can identify strategies to restore fish and habitat that could be impacted by flooding in the Situk River. Hubbard Glacier is expected to advance and dam Russell Fiord by the year 2000, and overflow from the fiord will flood the Situk River, drastically altering fish rearing habitat.

AN - 16730863; 3718496 AB - Differences between response of the bay scallop, Argopecten irradians, and the eastern oyster, Crassostrea virginica, to the dinoflagellate Prorocentrum minimum, led us to consider possible mechanisms by which dinoflagellates affect different bivalves. Juvenile scallops suffered rapid mortality accompanied by damage to adsorptive cells in the digestive diverticula and systemic pathologies characteristic of toxin effects when fed a diet including P. minimum. By contrast, larval and newly post-set oysters grew and developed poorly, but did not experience acute toxic effects, when fed algal diets including P. minimum. Large, dense accumulation bodies (persistent phagolysosomes) were present in digestive diverticula absorptive cells of young oysters fed P. minimum. When older juvenile oysters were exposed to the dinoflagellate, initial response was to filter, but not ingest P. minimum cells for approximately two weeks, after which oysters fed and grew normally, and digestive diverticula appeared healthy. Thus, presence and contents of accumulation bodies should hold clues about digestive interactions between bivalves and this dinoflagellate. Differences in responses of bivalve mollusks to dinoflagellates, such as Prorocentrum, may result from differences in digestive function, specifically the site at which dinoflagellate autolysosomes are digested.

The first two storms are the subject of this study. The entire life cycles of both storms were documented using a single ground-based Doppler radar. Radar reflectivity signatures of updraft summits and Doppler velocity signatures of divergence near storm top were used to deduce updraft evolution within the storms. Dual-Doppler radar observations from a ground-based radar and an airborne Doppler radar provided fragmentary documentation of the storms' life cycles. The splitting storms on that day were unusual in two distinct ways: (a) the left members of the splitting storms were the dominant and longer-lasting ones, and (b) none of the deduced updrafts were collocated with centers of vorticity signatures that would have indicated updraft rotation. Both of the left-moving storms had 10 sequential primary updrafts, whereas their right-hand counterparts had 3 or 4 primary updrafts. Initial formation of the right-flank updrafts lagged behind the initial formation of the left-flank updrafts by 40-70 min. All the individual updraft summits moved in the general direction of the mean wind. Sequential updraft development on the left and right flanks of the storms suggested that expanding gust fronts provided the propagational component of storm motion.

Analysis revealed that the anchovies contained up to 485 ppm domoic acid in their viscera. This was the first reported incidence of domoic acid-related mortality of any organism in the United States. After this reported outbreak we obtained frozen samples of anchovies that were harvested near Newport, CA, in April 1991 and found they contained 270 ppm domoic acid in their viscera. By May, average domoic acid levels in frozen anchovy samples from this same area were less than 1 ppm. In October 1991, domoic acid was detected in razor clams (Siliqua patula) from Oregon and Washington and appeared to peak (an average of 106 ppm for all Washington State beaches) in the first week of December 1991. The averages then declined to less than 20 ppm without 6 months. However, domoic acid was still present at low levels (averages <5 ppm) in razor clams from Washington state beaches in December 1993. Dungeness crab (Cancer magister) in Washington and Oregon were also found to contain domoic acid, but only in their viscera. Domoic acid concentrations in the raw viscera of individual crabs from Washington state in December 1991 averaged 13 ppm and ranged from 0.8 to 90 ppm. The highest average levels of domoic acid in Washington state crabs were in the Grays Harbor and Willapa Bay samples, 32 and 31 ppm, respectively. By 1992 domoic acid level averages were <5 ppm in preseason samples of Dungeness crab taken along the Oregon and Washington coasts, ranging from 0 to 71 ppm. The highest levels of domoic acid in 1992 (36-71 ppm) were recorded in samples taken early in that year (January through April).

The vertical datum to which these limits are referenced must be adjusted every 25 to 30 years due to differential isostatic rebound. Because crustal movement unequally changes the land-to-water relationship along Lake Superior's shoreline, the method by which the limits are established on a new datum could accelerate the natural effects of crustal movement with adverse effects on shoreline flood levels, navigation depths, and lake outflows. With the implementation of the new International Great Lakes Datum of 1985, a study was undertaken 1) to review the methods used to establish the limits on previous datums and 2) to quantify the changed land-to-water relationship between the limits established in 1902 and those referenced to the new datum.

An approach which estimates the extent the artificial reef functions as an aggregator of biomass is proposed, based on habitat and ecological relationships. Applications of this approach indicate that new production due to the artificial reef may be in the range of 0.02-0.5 kg/m super(3) while catches at artificial reefs can be in the range 5-20 kg/m super(3). Hence, in these examples, artificial reefs serve primarily to aggregate fishes.

Growth was estimated from weight-converted length increments of 142 Floy-tagged individuals at liberty for a median of 187 days. Egg production was estimated for females of three taxa (four species) as the product of the weight of batch egg production and spawning frequency (the latter determined from histological evidence of day-old postovulatory follicles). Milt production was deduced from male to female ratios of gonad weights for reproductive fish. Somatic growth rates varied three- to fourfold among the six species and, in part, reflected the distribution of maturity stages of intraspecific populations. On average, the per capita growth rates of taxa dominated by immature stages were faster than those dominated by large adults. Somatic production varied more than somatic growth rates (by a factor of 15), because of additional variations in standing stock biomass among populations. The somatic production of at least one species was underestimated as a result of a tag effect on growth. Weight-specific egg production varied only twofold among the three taxa examined, perhaps because fishes with smaller batch egg productions compensated by spawning more frequently, and vice versa. Estimates of weight-specific milt production further diverged because of the influence of relative testis-to-ovary weights that ranged from a small fraction to unity. Additional variation among taxa in total gonadal (egg plus milt) production was about one-half that of somatic production (a factor of eight). Besides representing interspecific differences in adult biomass, variations in gonadal production reflected intraspecific differences in the biomass contributions of the two sexes within the fraction of adults that were reproductively active. Despite likely substantial underestimates of gametic materials, gonadal production ranged from a large fraction to a large multiple of somatic production among the four species. Our observations suggest that the elaboration of tissue unrelated to yield is nontrivial and represents a major component of energy flow through the fishes in this reef system and perhaps others.

Three species of juvenile Alaskan flatfishes: rock sole (Pleuronectes bilineatus), yellowfin sole (P. asper), and Pacific halibut (Hippoglossus stenolepis) were tested in laboratory chambers containing contaminated mud or sand offered in combination with clean mud, sand or granule. The flatfishes were able to detect and avoid heavily oiled (2%) sediment, but they did not avoid lower concentrations of oiled sediment (0.05%). Oiled sediment was favoured over unoiled sediment if the unoiled sediment was of the grain size not preferred by that species. Oiled sand or mud was always preferred over unoiled granule. The observed lack of avoidance at concentrations likely to occur in the environment may lead to long-term exposure to contaminated sediment following a spill. Recruitment of juveniles may be affected if the exposure to oil is long enough to affect growth and survival.

AN - 16719946; 3704893 AB - Fifty standard concrete modules were deployed on a sand bottom to make 16 replicated artificial reefs of 1 to 8 modules/reef. Fish assemblages were monitored for species composition, abundance, and fish size, and compared to two natural control sites. We censused 127 species (107, 168 fishes) from artificial reefs, 93 species (16,495 fishes) on natural control reefs, and 17 species (1,040 fishes) on sand bottom from July 1987 to March 1989. Artificial reefs supported a diverse, abundant, and dynamic assemblage of fishes that were a mixture of species found in surrounding sand and natural reef habitats. Colonization (number of species, individuals, and biomass) was very rapid. Abundance varied seasonally with recruitment episodes tending to occur in the spring and summer followed by losses for the remainder of the year. Assemblages were quite variable on and between similar sized reefs. Fish and biomass densities were higher at artificial reefs than on sand and natural reefs. Resident fish biomass varied less than resident fish numbers, because individual growth compensated for mortality after recruitment episodes. Reef size significantly influenced total numbers of species, individuals, and biomass. Smaller reefs had greater fish density while larger reefs had higher biomass density from larger, but fewer, individuals. Multiple small reefs supported more individuals and more species than one large reef of equal material. Fishes recruited by larval settlement accounted for 36% of the total resident abundance but only 2% of total biomass. As reef size increased, older juvenile or adult colonists comprised a greater percentage of total biomass (94% to 99%). Assemblage importance percentages (based on abundance, biomass, and frequency) were divided between residents (64%), visitors (20%), and transients (16%). Economically important species comprised 61% of the biomass and 55% of the individuals, among which settlers accounted for 94.3% of individuals but only 5.7% of their total biomass. The most highly valued species were visitors or residents that utilized the reefs after first settling elsewhere. These results showed that data on artificial reef assemblages based solely on the abundance of resident species are biased. Data on visitors, transients, frequency-of-occurrence, and biomass are important in evaluating bias. Results provided a partial test and support for a model predicting the importance of attraction over production for artificial reefs located in areas with high reef availability.

Visual assessments of fish assemblages were conducted in 1989 and 1990 in Onslow Bay, North Carolina, to quantify pelagic and demersal fishes associated with a natural rock outcrop and two experimental treatments of artificial habitats. The vertical relief component of both experimental habitats was held constant, resulting in an experimental design which allowed for a test of the effects of structural volume and complexity on fish abundance and pelagic prey/predator interactions. Experimental habitats were deployed 60 m perpendicular to a natural rock ledge in 25.5 m of seawater and floated 3 m off the bottom. Data supported the hypothesis that fish abundance is directly proportional to structural volume and complexity. Species richness and assemblage similarity indices indicated that experimental habitats deployed 3 m off the substrate and in close proximity to one another aggregated similar fish species regardless of structural volume and complexity. Analyses of pelagic fish abundance data suggested inverse relationships between predator and prey abundance. As shelter availability decreased, pelagic baitfish abundances decreased and predator abundances increased.

The consistent methodologies used to develop and compile the data enables comparative assessments across the Nation's estuaries. The NEI currently includes national data sets describing the physical, hydrologic, and natural resource characteristics for 106 estuaries of the contiguous United States. This paper provides an overview of the NEI, defining its importance, uses, and future vision. Although the knowledge available to effectively conserve and manage the Nation's estuarine resource base is limited, the NEI and associated data bases provide an important tool for assessing, comparing, and contrasting the biological and physical characteristics of the Nation's estuaries.

Significant and fundamental changes are required in how science, management, and public policy are conducted if the Nation is to effectively address its estuarine and coastal crisis with the limited resources available. Although many agree that the Nation's coastal resources and environmental quality are suffering, few have been able to accurately diagnose the causes and recommend possible cures. This paper identifies and describes several key aspects of today's changing decisionmaking context, offers a number of prescriptive and hopefully provocative observations and solutions, and summarizes briefly how several programs and activities of NOAA's Strategic Environmental Assessment Program continue to evolve as they provide information for decisionmaking in this changing context.

The NECOP study was initiated by the Coastal Ocean Program of the National Oceanic and Atmospheric Administration (NOAA) in 1989 to address the effects of nutrient discharge in the coastal waters of the United States. The basic hypothesis posed for NECOP is that the addition of anthropogenic nutrients from sewage, agriculture, industrial sources, and suburban runoff have contributed to the development of eutrophication in coastal waters with significant impacts on water quality. The coastal waters of the northern Gulf of Mexico were selected as the initial study site for NECOP based on a set of criteria developed by NOAA scientists and their academic colleagues. The criteria for the location of study include: A clear anthropogenic signal; a resultant nutrient-enhanced productivity of significant magnitude; a demonstrable impact of enhanced production on coastal environmental quality, and renewable resources of significant value.

Such multi-ridge-segment surveys of venting are accomplished most efficiently by mapping the distribution and intensity of hydrothermal plumes. In November 1991, we mapped hydrothermal temperature ( Delta theta ) and light attenuation ( Delta c) anomalies above the East Pacific Rise (EPR) continuously from 8 degree 40' to 11 degree 50'N, a fast spreading ridge crest portion bisected by the Clipperton Transform Fault. Plume distributions show a precise correlation with the distribution of active vents where video coverage of the axial caldera is exhaustive (9 degree 09'-54'N). Elsewhere in the study area the sketchy knowledge of vent locations gleaned from scattered camera tows predicts only poorly the large-scale hydrothermal pattern revealed by our plume studies. Plumes were most intense between 9 degree 42' and 9 degree 54'N, directly over a March/April, 1991, seafloor eruption. These plumes had exceptionally high Delta c/ Delta theta ratios compared to the rest of the study area; we suggest that the phase-separated gas-rich vent fluids discharging here fertilize an abundant population of bacteria. Hydrothermal plume distributions define three categories: intense and continuous (8 degree 48'-8 degree 58'N, 9 degree 29'-10 degree 01'N and 11 degree 05'-11 degree 27'N), weak and discontinuous (8 degree 58'-9 degree 29'N) and negligible. The location of each category is virtually congruent with areas that are, respectively, magmatically robust, magmatically weak and magmatically starved, as inferred from previous measurements of axial bathymetric undulations, cross-axis inflation and magma chamber depth and continuity. This congruency implies a fine-scale spatial and temporal connection between magmatic fluctuations and hydrothermal venting. We thus speculate that, at least along this fast spreading section of the EPR, cyclic replenishment, eruption and freezing of the thin axial melt lens exerts greater control over hydrothermal venting than the more enduring zones of crystal mush and hot rock. We found intense, and continuous, plumes along 33% of the surveyed ridge crest, an observation implying that any point on the ridge is, on average, hydrothermally active one-third of the time. Combining this result with the 20% plume coverage found along the medium-rate Juan de Fuca Ridge suggests that superfast ( similar to 150 mm/yr) spreading ridges should support vigorous venting along similar to 50% of their length, if spreading rate and along-axis plume coverage are linearly related.

The capability to adequately respond to an oil spill in Alaska can be hampered by a number of critical factors, which combined with the potential to experience large spills, require tools," other than mechanical response such as in-situ burning (ISB), be preplanned and immediately available to responders and government officials to ensure an adequate response to spill events. Because of this, the Alaska Regional Response Team (ARRT) has been working over the past 2 to 3 years to develop procedures and guidelines, scientifically based, to facilitate the decision process regarding ISB. The first major hurdle was developing a consensus that, outside the immediate region of the fire, the potentially most damaging effects of the smoke plume were those on the health and safety of the general population. The natural resource agencies were unable to document any adverse effects of the smoke plume on biological populations and/or habitats. The second hurdle occurred with the determination that particulates in the smoke plume less than 10 microns in diameter were the major culprit causing potential adverse effects to the general population. As a result, the Alaska Hazardous Substances Spill Technology Review Council funded the National Institute of Standards and Technology (NIST) to model downwind particulate concentrations for the burning of North Slope and Cook Inlet crude oils under typical winter and summer conditions in southern and northern Alaska. Based on a very conservative interpretation of the National Ambient Air Quality Standards (NAAQS), a particulate level of 150 micrograms per cubic meter ( mu g/m super(3)) - real time, one hour average - was selected as the acceptable exposure level to the general population. Using these parameters, the Alaska ISB guidelines now allow the Unified Command (FOSC and SOSC) to authorize ISB without RRT consultation. Provisions have been developed to conduct a trial burn, conduct controlled and uncontrolled burns, extinguish a burn, monitor a burn, and notify the public of a burn.

These collaborative efforts may be the greatest contribution that the sanctuary program can bring to the area of ocean management. Currently the oceans are managed resource by resource with little regard given to an integrated view of ecosystems. The interdisciplinary approach of these cooperative agreements may be a necessary first step toward a more comprehensive policy of ocean management.

The industry now produces approximately 100 000 mt of feed per year, up from less than 8000 mt 6 or 7 years ago. The number of feed producers has increased from several to 22 during this period. The quality of Chilean salmon feed has improved greatly in the last few years as well, advancing from the North American technology and formulations used in the early 1970s to produce moist feeds and pelleted salmon feeds to the industry's current level of quality, where the best feed producers manufacture feeds equivalent to the best salmon feeds produced in Europe and North America. In making these advances, the Chilean industry has not simply copied European and North American technology, but rather taken the best elements of foreign fish feed manufacturing and adapted them to Chilean needs. Both pelleted and extruded feeds are being produced for coho salmon, Atlantic salmon, and rainbow trout. The advantages normally associated with extruded feeds, such as higher lipid content and a slowly sinking pellet, are not critical concerns in the Chilean salmon industry. The range of feed ingredients available to the Chilean feed industry is lower than in Europe and North America, which limits the number of possible feed formulations in Chilean salmonid feeds. Thus, the quality of feed ingredients, particularly fish meal, and the quality of manufacturing are more important determinants of feed quality than is feed formulation. Future needs for the Chilean fish feed industry include less expensive and more efficient methods of pigmentation, a better understanding of the effects of biogenic amines on fish growth and product quality, and development of feeds that are less costly per kilogram of product sold. In the future, development of low-polluting feeds may also be desirable. JF - Aquaculture AU - Hardy, R W AU - Castro, E C AD - U.S. Dep. Commerce, NOAA, Northwest Fish. Sci. Cent., Utilization Res.

Environmental contamination is known to affect many aspects of lobster biology. Heavy metals, pesticides, pulp mill effluent, petroleum hydrocarbons and other pollutants can adversely affect lobster physiology and behavior. Sublethal concentrations of contaminants can stress lobsters, making them more susceptible to disease or other conditions that would normally be tolerated. Lobster embryos and larvae, particularly the first-stage, are sensitive to a variety of organic and metal pollutants. Sediments in New Bedford Harbor, Massachusetts, are heavily contaminated with polychlorinated biphenyls (PCBs); edible tissues of lobsters collected there have been found to contain PCB concentrations exceeding the FDA action level of 2 mu g/g wet wt. PCBs are strongly lipophilic and accumulate in fatty tissues including egg masses. Metals and PCBs are contaminants of concern in Long Island Sound. This study examines whether field exposure of ovigerous female lobsters to PCBs results in subsequent contamination of embryos, first-stage larvae, postlarvae, and juvenile offspring of "berried" lobsters from New Bedford Harbor and selected locations in Long Island Sound. Metal contamination in the embryos and offspring of Long Island Sound lobsters was also measured.

Gravimetrically estimated fecundities were compared in 1985-1991 between California, the southern extent of the species' distribution, and coastal waters of Washington, near the center of the species' abundance, where yellowtail rockfish are most heavily fished. California yellowtail rockfish were older, smaller in weight and length, and had smaller mesenteric fat deposits and more extensive disease and parasite pathologies than Washington fish. Egg production of this comparatively fecund viviparous fish increased linearly and sigmoidally with body weight and length, and asymptotically with age. Significant interannual differences were found in fecundities of young fish (age 14) or in young or old Washington fish. Washington yellowtail rockfish had higher group fecundities because they were larger at age. Rate-specific fecundities were significantly higher in young Washington fish. Predictive models of fecundity were highly correlated for young yellowtail rockfish, less so for old fish. Although fecundity of young fish depended on weight, length, and age, that of old fish was age-independent. Our findings show age-dependent interannual and geographic differences in reproductive effort, which suggest population-specific reproductive life histories.

Left sagittal otoliths from these fish were embedded in epoxy resin, and transverse sections through the foci were prepared. With hyaline zones considered as annual increments, ages ranged from 1 to 11 for 608 winter flounder; 97% of the fish were younger than age 5. The dorsoventral otolith diameter was determined by linear regression analyses to be the best (r super(2) = 0.90) of six "radial" axes for increment measurements. Marginal increment analyses for ages 1-4 showed that the increments, each composed of one opaque and one hyaline zone, are deposited annually, which clearly verified sectioned otolith ages for age-2 and age-3 fish. Opaque edges were prevalent in May, June, and July. Sectioned otoliths from winter flounder can provide clear increments and measurable increment widths through age 11. Two individuals read 369 sectioned otoliths and 116 whole otoliths; one individual read 155 scales twice. Precision between readers and aging methods was relatively high (average percent error, 1.5-4.5).

Aerosol samples were also collected on board research ships in four cruises over the East China Sea and Western Pacific Ocean to determine BC distribution. The data were used to verify a simple one-dimensional transport model. In the marine boundary layer with prevailing westerlies of 5 m/s, the BC total deposition rate, including both dry deposition and wet deposition, was computed as -1 x 10 super(-5)/s, and the half-life was estimated to be 19 h. The residence time was approximately 5 d, concentrations subsequently diminishing to the background level. Longer lifetime and farther transport would be probable in the free troposphere. Because BC particles have great surface areas and are very absorbent of electromagnetic waves, their concentration and distribution in the atmosphere may have profound effects on radiation budgets and climate change.

ER - TY - JOUR T1 - A multiseason climate forecast system at the National Meteorological Center AN - 16704212; 3635946 AB - Coupled Model Project was established at the National Meteorological Center (NMC) in January 1991 to develop a multiseason forecast system based on coupled ocean-atmosphere general circulation models. This provided a focus to combine expertise in near real-time ocean modeling and analyses situated in the Climate Analysis Center (CAC) with expertise in atmospheric modeling and data assimilation in the Development Division. Since the inception of the project, considerable progress has been made toward establishing a coupled forecast system. A T40 version of NMC's operational global medium-range forecast model (MRF) has been modified so as to have improved response to boundary forcing from the Tropics. An ocean reanalysis has been performed for the Pacific basin starting from July 1982 to present and uses a dynamical model-based assimilation system. This also provides the ocean initial conditions for coupled forecast experiments. The current coupled forecast model consists of an active Pacific Ocean model coupled to the T40 version of the NMC's MRF.

A forecast of future recruitment was made based on projected sea levels (Polovina and Mitchum, 1992). This note updates that forecast with two more years of data. These results provide some additional support to our original hypothesis that a positive relationship exists between the strength of the Subtropical Countercurrent and local larval survival, retention, and recruitment to the fishery at Maro Reef (Polovina and Mitchum, 1992).

The climatic change resulted in increased mixed layer depth and the frequency of deep mixing events, particularly during Jan-Mar. A number of biological time series for species ranging from primary to apex levels in the North-western Hawaiian Islands, show corresponding declines in productivity of 30-50% from the early 1980s to the present. We hypothesize that during the early 1980s, increased mixing due to the climate event resulted in greater nutrient input into the euphotic zone and ultimately increased ecosystem productivity. Productivity over a range of trophic levels declined when the climate event ended.

Recently, large numbers of this species were taken incidentally during research surveys conducted at Southeast Hancock Seamount in the central North Pacific Ocean. The information collected during 1985 to 1988 from these surveys is used to describe the life history, depth distribution, and biology of S. mitsukurii. Bathymetric distributional patterns of female and male S. mitsukurii differed slightly, although bottom longline catches revealed a depth distribution extending from the summit (260 m) to 740 m for both sexes. Males generally were found deeper than females. In addition, the size of males generally increased with depth whereas no apparent trend was observed for females. Reproductive parameters for both sexes are presented. Males tended to reach maturity at smaller sizes than did females. Gravid females had broods of up to six uterine embryos. Length of young close to parturition was 21-26 cm. Tentative estimates of age and growth were made from dorsal spine increment counts. Maximum ages were 27 years for females and 18 years for males. Females exhibited more rapid growth than males after about age 9. The diet of S. mitsukurii included both benthic and mesopelagic prey. Fishes, cephalopods, and crustaceans were the major components of the diet. Comparison of the biological characteristics suggest that this species is probably typical of other slow-growing, low fecund members of the genus Squalus. The 50% decline in catch rates observed during this study suggests that the number of S. mitsukurii on the seamount declined dramatically, possibly as a result of overfishing.

It is now recognized that eggs and larvae present a wide array of characters suitable for systematic analysis that are largely independent of adult characters. Fisheries recruitment studies focus on survival of eggs and larvae as the most important factor influencing variations in population abundance. A requisite to these studies is detailed information on the appearance of fish eggs and larvae in order to identify them in plankton samples. This paper reviews the proportions of fish species for which at least illustrations of eggs and larvae, sufficient to permit their identification in plankton samples, have been published worldwide and by geographic region. Factors which may influence differences in proportion of identifiable eggs and larvae by region are discussed. Factors considered important include species diversity, a history of important commercial fisheries, research emphasis, and interests of individual scientists in various regions. We conclude that although eggs and larvae of most species can now be identified in some regions of the world, there are still gaps in our knowledge that prevent realizing the full potential of ichthyoplankton studies in systematic and fisheries research. Filling these gaps will require continued traditional morphological research as well as application of biochemical genetic and rearing techniques.

Numbers of species and overall densities were highest on ledge habitat, intermediate on live-bottom (three categories of low relief [<15 cm] rock outcroppings covered by algae and macrofauna), and lowest over sand. On average, abundance over ledges exceeded that over sand bottoms by a factor of 50. Generally, community composition at sites over ledges and dense live-bottom areas was similar and distinct from sites found over sparse live-bottom and sand. Many species were found in more than one habitat and few individual species could be considered indicators of a single habitat type. A nondestructive, repeatable procedure of randomly dispersed video transects was devised for assessing diurnally active fishes.
