TY - BOOK T1 - The Fraunhofer Society: a unique German contract research organization comes to America AN - 59848158; 2001-0801770 AB - Describes the Fraunhofer Gesellschaft as a successful mechanism of industry, university, and government collaboration; dynamics of model, factors resulting in its internationalization strategy, and growing US presence and use to advance US industrial competitiveness; 1990s, chiefly. Each Fraunhofer partner has a specific role: universities undertake basic research and develop student/employees; government performs research at its own labs and provides funding to the Frauhofer Society to keep contract research costs down; industry provides contracts, manufacturing, and marketing capabilities; and the Institutes themselves develop engineers and act as a conduit between basic research and industrialization.

These high values, measured during gas extraction by crushing in vacuum, are similar to the highest magmatic (super 3) He/ (super 4) He ratios found in young terrestrial volcanic rocks. By analogy with young basalts, in which crushing selectively extracts magmatic helium, any significant cosmogenic (super 3) He appears to be absent in these picrites. Additional evidence for the absence of cosmogenic helium is provided by fusion results on the crushed olivine powders and by a single stepwise crushing experiment, in which only magmatic and radiogenic helium components are resolvable. The West Greenland picrites have Pb, Nd and Sr isotope compositions which overlap those found in picrites from Iceland and in basalts from Loihi Seamount, localities which today also have high (super 3) He/ (super 4) He ratios. Isotopic variations in He, Pb, Nd and Sr for the West Greenland picrites are interpreted to largely result from interaction of the early Iceland mantle plume with the upper mantle during plume ascent and dispersion beneath the continental lithosphere. The presence of high (super 3) He/ (super 4) He ratios in West Greenland, and the onset of magmatism across the North Atlantic Volcanic Province near 62 Ma, supports the hypothesis for very rapid dispersion (>1 m/year) of mantle plume head material during the earliest stages of plume impact, as predicted in recent numerical simulations of plume behavior during thermal mantle convection with non-Newtonian rheology.

Stable element analyses were combined with radiometric measurements to determine the most probable geochemical host phases of these actinides in reference sediment IAEA-135. (super 241) Am results indicate an association with carbonate minerals and organic matter. The extraction profile of (super 238) U was similar to that of refractory elements Al, Ti, and K. (super 239/240) Pu data suggest a fractionation of Pu into Fe-bearing phases of varying solubility. The reproducibility of the method was quite good (replicates agreed to within 10% at a 95% confidence level).

The average time for the dissemination of these warnings has been about 55 minutes. In most cases tsunami destruction has been confined to localities that are within one hour's tsunami travel time from the source. While the Warning Center's warnings may not reach those most affected by recent tsunamis, the information is nevertheless of great value to those emergency managers further down stream of the spreading tsunami. An examination of the warning process indicates the need for more feedback from the participants receiving the warnings regarding the applicability of the information to their needs and, if they are affected by the tsunami, a timely summary of these affects that can be used to ascertain the severity of the tsunami. The study also points up the critical need for independently functioning regional tsunami warning centers.

The program was called SEMS, for the Seafloor Earthquake Measurement System. The purpose of the program was to characterize the nature of the response of earthquake ground motions for use in the design and reassessment of offshore platforms used in petroleum drilling and production. The United States Geological Survey (USGS) was given a contract to provide seismological analysis of data obtained from the SEMS program and compared it to data from earthquakes measured onshore. This paper provides an overview of the work by the USGS on this initivative.

The performance based design is an emerging art, which was born from the lessons learned from the recent earthquakes in 1990's. This is to overcome the limitation in the conventional seismic design, which was based on the force balance against a design seismic force. The performance based design is a user friendly approach to take into account the requirements of the seismic performance of a structure against the probabilistic occurrence of earthquake motions. This paper is an initial proposal of the seismic performance based design for port structures.

They provide critical quantitative measurements of damaging earthquakes in urban environments needed for mitigation of future earthquake losses. The present critical lack of strong-motion information emphasizes that urgent action is required to significantly increase resources to adequately record future damaging earthquakes. Recent estimates for the US suggest that an urgent need to record the next major earthquake adequately throughout stricken urban areas requires that instrumentation and recording efforts be increased by nearly 20 times within the next five to ten years (Stepp, 1997; Borcherdt, et al., 1997). Justification for this dramatic increase as prepared by the "Committee for the Future of the US National Strong-Motion Program" (Borcherdt, ed., 1997) is summarized here.

Recent years, a strong demand for the preservation of natural environments has been accompanied by the need for bridge construction methods that have minimal effects on nature. To meet this new requirement, high bridge piers must be constructed. In response to these circumstances, rationalize execution and to develop the 3H (Hybrid Hollow High Pier) Method: a new high bridge pier structure that is both economical and provides earthquake resistance.

Consequently, if cyclic strengths, either from laboratory measurements performed at a confining stress of 1 atm or estimated from correlations to in situ measurements such as Standard Penetration Tests (SPT), are linearly extrapolated to higher effective confining stress levels, the calculated liquefaction resistances may be too high. The effect of confining stress on liquefaction resistance is further complicated by soil compressibility and stress history. The state-of-the-practice approach to account for the non-linear relationship between liquefaction resistance and vertical effective stress is to use published charts derived from existing laboratory data on similar materials or to determine a site specific relationship with a comprehensive laboratory testing program. Whichever approach is used, liquefaction resistance is conventionally represented as the Cyclic Resistance Ratio (CRR, the ratio of cyclic shear strength divided by the vertical effective stress, sigma (sub v) '). For a given soil at a given consistency and stress history, the CRR generally decreases with increasing vertical effective stress. This decrease is described by the factor K (sub sigma ) which is defined as the ratio of CRR for a given sigma (sub v) ' to the CRR at a vertical effective stress of 1 atm, CRR (sub 1) (compared at the same relative density).

The postulated maximum credible earthquake (MCE) for Hoover Dam is a magnitude Ms 6.75 on the Mead Slope Fault. Initial structural finite element analysis calculated stresses larger than the tensile strength on the upper portions of the dam. More sophisticated analysis followed when additional data was obtained for material properties and seismic loading. The first approach was a linear-elastic analysis incorporating foundation-structure interaction with mass in the foundation. The second approach was a non-linear analysis incorporating concrete cracking and contraction joint interaction using smeared crack techniques and kinematic stability analysis of the top of the dam.

The observation system includes 11 observation sites and a control center. A number of records with intermediate amplitudes have been obtained to this date. In this report, the earthquake observation system is introduced at first. The description includes the outline of the geological condition of the Sendai area, the objective area of the observation, the surface geology of the 11 observation sites from the investigation in sites, and the recorded data until the project started. During the period, the seismic activity of the area was not so high. Therefore, the amplitudes of acceleration records are not large enough to be called "strong motion". However, these data are essential for the purpose to examine the dynamic amplification property of the surface soils.

The building code in Japan will be changed from current prescriptive type into performance-based type in a few years. In responding this announcement, the performance-based building code is now under development at the Building Research Institute (BRI). In this paper, presented is the framework and concepts of the performance-based seismic and structural provisions in Japan proposed by BRI. In the principles of structural safety, the required performance and loads/forces levels are clearly defined. There are four routes in verification procedures and associated structural specifications following the principles of structural safety; proposed route, conventional route, small building route requiring no calculation, and other route including alternative verification procedures, deemed-to-satisfy provisions, and expert judgments. Seismic effects to buildings are considered on the basis of basic seismic design spectrum defined at the engineering bedrock under surface soil layers. There are three levels in the objectives and requirements to building structures and loads/forces levels. The objectives are life safety, damage prevention, and continuous normal operation of a building. The principle of verification procedures is that the predicted response values should not exceed the estimated limit values. The newly proposed verification procedure for major earthquakes is illustrated, as all others remain basically the same as those actually in use. There are indeed various analytical methods for predicting the response of structures subjected to earthquake excitations. The one which is shown here is based on the equivalent single-degree-of-freedom system and response spectrum method.

It has emphasized the importance of earthquake engineering research into why and how structures collapse in real earthquake conditions and these processes are reproduced numerically. Considering the lessons learnt from recent earthquake disasters, NIED plan to construct a "3-D Full Scale Earthquake Testing Facility," which will be able to simulate the process of destruction of structures. This facility will be a central tool in a new concept of research bases for earthquake disaster prevention. NIED was conducted the research and development of core technology, such as the big and high performance hydraulic actuators, which have a long displacement and high velocity, and high performance three dimensional link joint since 1995 by the 4 year project. We constructed the prototype shaking table systems and confirmed the performance tests. NIED will begin the design and construction of this new facility in fiscal year 1998. This paper summarizes the fundamental concept of the facility and the result of R&D of core technology.

The factors controlling the amplitude of such motion, however, are not widely understood. Compared to the body wave, the velocity of the surface wave is much less, and, as a result, the curvature of the wavefront and the geometric spreading are much less. The surface wave behaves approximately as if it were generated by a line source in a two-dimensional medium. On the other hand the low-Q basin sediments produce significant anelastic attenuation, even at relatively long periods. A study of pseudovelocity response spectra of records of the 1971 San Fernando and 1994 Northridge earthquakes at sites in the Los Angeles Basin shows that late-arriving surface waves with group velocities of about 1 km/sec dominate the ground motion for periods of 3 sec and longer. The rate of amplitude decay for these waves is less than for the body waves and depends significantly on period, with smaller decay for longer periods. The amplitude can be modeled by anelastic attenuation with decay proportional to the exponential of distance multiplied by an attenuation coefficient. Methods for estimating the response spectral amplitudes for these waves in future earthquakes are presented based on either the San Fernando or Northridge data. The response spectral amplitude of surface waves from the Northridge earthquake is less than from the San Fernando earthquake by factors as large as four. The surprisingly large difference between the San Fernando and Northridge earthquakes can be explained, at least in part, by directivity. Estimates of response values in future earthquakes based on the two different data sets give a sense of the range of possibilities. These estimates are based on data from the Los Angeles Basin, but, in the absence of other data, they could be applied to sites in other deep Quaternary basins. The results presented in this paper indicate that inclusion of anelastic attenuation may be essential in modeling ground motion in deep sedimentary basins. Future progress in understanding strong motion from basin surface waves calls for attention to faithful recording of the long-period components of ground motion and to recording motion for times long enough to include the late-arriving surface waves.

The overall objective of the total program is to improve seismic safety practices in both countries through cooperative studies to determine the relationship among full-scale tests, small-scale tests, component tests, and related analytical and design implication studies. A five-year research program on Composite and Hybrid Structures was recommended to start in 1993 fiscal as the Phase 5 based on a number of technical meetings between the U.S. and Japan. Because of diverse and broad scope of the subject area, the research program was organized into the following four groups: Concrete Filled Tube Column Systems; Reinforced Concrete (RC) and Steel Reinforced Concrete (SRC) Column Systems; RC/SRC Wall Systems; and New Materials, Elements and Systems. In addition to the objectives of the total program, Phase 5 aimed at (1) developing design guidelines (for a unified code development) for typical composite and hybrid structures, and (2) developing new and innovative composite structural elements and hybrid systems using advanced new materials and/or devices. Japan side has just completed his assignment of the cooperative research work in the fiscal year of 1997. This report presents the outlines of the research conducted during five years and the general contents of the proposed draft guidelines.

This system is expected to provide quick and appropriate decision making in all three phases, "preparation", "emergency measures" and "recovery/rehabilitation". Since April 1996, the National Land Agency has been operating the Early Estimation System (EES) which automatically estimates the scale of damage caused by an earthquake using the very limited information available immediately after an earthquake occurs. Currently, the agency is pursuing the development of an Emergency Measures Support System (EMS), which will consolidate and share information through the construction of an on-line network linked with other disaster-prevention organizations, and utilize such information in support of emergency measures such as rescue and medical care, emergency transportation, evacuation, lifelines, and volunteers.

This project has been made through the joint research program between Public Works Research Institute, Public Works Research Center and 17 private companies. Developed seismic isolation systems for the underground structures are made by constructing the isolation materials with low-shear modulus around the underground structures to absorb the effect of ground deformation. Five kinds of seismic isolation materials have been developed and the analysis and design methods for the underground structures with the seismic isolation systems have been also studied and developed. The final accomplishment is compiled as a "Draft Manual for Seismic Isolation Design of Underground Structures" in March 1998.

Performance goals are defined in terms of a minimum annual seismic failure frequency. Pushover analyses are used to determine the building's ultimate capacity and relate the capacity to roof drift and joint rotation. Nonlinear dynamic analyses are used to quantify the building's drift versus earthquake magnitude using a suite of time histories representing varying soil conditions and levels of seismic hazard. A probabilistic correlation between joint rotation and damage state is developed from experimental data. The results of the deterministic pushover and nonlinear time history analyses are evaluated statistically to develop a probability of seismic failure or fragility. The building fragility level is convolved with the seismic hazard curve to determine annual seismic failure frequency.

Accelerometers are the most common instruments used to monitor structural systems during earthquakes or strong winds, but to arrive at displacements requires processing including double integration. In most cases, such processing does not take place in real-time or near real-time because of requisite steps including choice of filters for signal processing. These choices could introduce errors at periods relevant to structural response. However, recent advances in Global Positioning System (GPS) technology recording at 10 samples per second (sps) allows reliable monitoring of long-period structures such as suspension or cable-stayed bridges and tall buildings. GPS units with a capability of resolving motion at the centimeter level (+ or -1 cm for horizontal, + or -2 cm for vertical accuracy) with sampling rates of 10 sps are now available from several manufacturers. The majority of tall buildings (20-40 stories or more) are flexible steel framed structures whose fundamental period (T, in seconds) can be estimated with the empirical formula T = 0.1 N, where N is the number of stories of a building. Thus, the frequencies corresponding to the fundamental periods of most buildings over 20 stories are 10-20 times the Nyquist frequency of the sampling, which is sufficient to assess accurately its average drift ratio. With this method, displacement is measured directly in real-time. In this paper, we discuss the scientific justification and feasibility of using GPS technology to monitor long-period structures. We describe an experiment simulating the response of a tall building. The results indicate that sampling at 10 sps provides a clear and accurate response history from which drift ratios and dynamic characteristics of the specimen can be derived. The paper discusses in detail how data recorded from tall buildings monitored with GPS units can be used by engineers and building owners or managers to assess the building performance during extreme motions caused by earthquakes and strong winds, by establishing threshold displacements or drift ratios and identifying changing dynamic characteristics. Such information can then be used to secure public safety and/or take steps to improve the performance of the building.

Two points are included in the paper: i.g., a new system architecture to realize SIS with systematic control, possibility of extension and the independence of the subsystems, and several element technologies applicable to the subsystems of SIS. The proposed concept does not only concentrate on the technologies of the supply-side, but also the philosophy and the technologies that is "objective oriented." As the counter-earthquake activity system is responsible many complex jobs at a time, and as the information technologies is becoming highly technical, the concept introduced here is very much help for the personnel of the counter-earthquake activity system.

In case of houses, it is difficult to elongate a period of building by laminated rubber bearing isolators because of the light weight of building. In addition to rubber bearing devices, sliding and rolling type devices are needed to be developed or applied. In this paper, the effects of base isolation on response of houses and mechanical characteristics of various kinds of seismic isolators will be discussed. Shaking table tests of base isolated house models were carried out. Various kinds of isolators, such as rubber, sliding, and rolling bearings were tested. The effect of these isolators on the response of a superstructure during earthquakes has been demonstrated, through the comparison with response for a non-isolated house. It is shown that the response of houses is remarkably dependent on characteristics of isolators.

For the purpose of the geotechnical earthquake studies, a powerful electro-hydraulic shaking table designed to work in the centrifuge has also been developed. This shaking table provides 40G shaking acceleration to a model of 1 ton, which acceleration is equivalent to the maximum ground acceleration observed during the 1995 Hyogoken Nanbu earthquake for a model at 50G centrifugal acceleration field. The centrifuge has been under extensive use to investigate various geotechnical problem. Results of centrifuge tests carried out so far are briefly described.

The research work in Japan started in fiscal year 1993. However, fuller participation of researchers on both sides started in early summer 1995. The sponsorship of the program is by the National Science Foundation in the U.S. and by the Ministry of Construction along with a number of industry groups in Japan. This paper presents a brief status report of the program and research progress made to date on the U.S. side. Because of diverse and broad scope of the subject area, the research program is organized into the following four groups: Concrete Filled Tube Column Systems (CFT); Reinforced Concrete (RC) and Steel Reinforced Concrete (SRC) Column Systems (RCS); and RC/SRC Wall Systems (HWS); New Materials, Elements and Systems (RFI). A theme structure with well selected layout, geometry and design loads for the research is also presented, which provides a common focus for various systems to be studied, and also a common prototype structure from which the components and sub-assemblages are drawn.

However, there was no damage on dams which affected the their safety. This paper introduces the characteristics of ground acceleration observed at dam sites during the Kobe Earthquake and discusses the effect of vertical seismic motion and the safety of concrete gravity dams in such big earthquakes. The result of the dynamic analysis shows that concrete gravity dams have the high safety against such big earthquakes.

At this earthquake, information was very poor. Since then various cities had committees to modify these situations. Yokosuka City and NTT (Nipon Telephone and Telegram) (Chairman was myself) started the committee in the same year of March 1. They were using the ordinary multimedia because of difficulties of using extra methods (like the battery not working) when a devastating earthquake comes. In 2 years, we could finish and realize basic ideas. JF - National Institute of Standards and Technology Special Publication(NIST) AU - Watabe, Makoto AU - Hirokawa, Satomi A2 - Raufaste, Noel J.

The investigations about the mortality and morbidity due to both direct and indirect health effects at the community level are required to identify the most effective countermeasures in the pre-impact and post impact phase. As an example of indirect health effects, age-adjusted death rates of acute myocardial infarction were compared among several affected regions. In Nada, Higashi-Nada, Hyogo, Nagata districts in Kobe City we observed the sharp increase in the average death rates between January and March, 1995 in comparison with 1994 and 1996. Outside of Kobe City, the similar increase was observed in Amagasaki and Tsuna. The different patterns in the increase of rates between January and March, 1995 are suggestive of the multiple risk factors. The further investigation is required to identify the environmental factors (structural and non-structural) to reduce the total health outcomes.

As a wrap-up to the program, research results are being reviewed and assessed in order to determine the impact that their results may have on the future development of a consistent seismic design specification for highway structures. This paper summarizes some of the important results of the research conducted under the program and discusses issues resulting from this impact assessment task with respect to expected effects on future design practice.

The maximum recovery of silicic acid is achieved by thawing the frozen samples in a refrigerator (at 4 degree C) in the dark for at least four days. This method significantly improves the recovery of silicic acid from frozen fresh water samples. It also permits close to 100% recovery of reactive silicic acid from frozen seawater samples even after three months storage.

Data on abundance and distribution are typically scarce for rare species and are mostly in the form of incidental observations, such as fisheries bycatch or museum collections. An objective and quantitative method of evaluating the status of a rare fish species in selected systems - one that is based on incidental observations and that could be used to provide a first warning to managers that a species may be extirpated - would be highly desirable. In this paper, we review two methods that use incidental observations for estimating the probability that a species is extirpated, and we demonstrate the methods with available data sets for Atlantic sturgeon Acipenser oxyrinchus and Alabama sturgeon Scaphirhynchus suttkusi. Special considerations should be made when applying the methods to data sets for fish species. We recommend against using or combining data sets that contain both early life stage and adult observations, and we recommend that priority should be given to data sets obtained in preferred habitat areas.

A group of juvenile chinook salmon was graded by size into small and large categories; half the fish in each category were reared at an elevated temperature beginning in mid-February, resulting in four distinct treatment groups: large-warm, large-cool, small-warm, and small-cool. Fish from warmwater treatment groups displayed significantly higher growth rates through the spring than coolwater groups. Fish were released into a natural creek on two dates (25 March, release 1 and 12 April, release 2), and downstream movement was monitored. For each release, fish that migrated past a weir within the first 5 d postrelease had significantly higher spring growth rates than fish that did not migrate within that period. A similar comparison of release length to migration demonstrated significant differences only in release 2. Also for release 2, fish from the large-warm and small-warm treatment groups were recovered in higher proportions than fish from large-cool and small-cool groups. These results indicate that fish with relatively higher spring growth rates moved downstream sooner than fish with relatively lower growth rates. Furthermore, smolt size and migration were related with larger fish moving downstream sooner than smaller fish; however, this relation was weaker than that found between growth rate and migration.

Our evaluations were performed systematically over large (1/4 ha) sites in order to make generalizations as to the effect of bioturbation at the scale at which seagrass landscape patterns are discerned. Eighteen 50 x 50 m sites, representing a wide range of seagrass bottom cover, were surveyed seasonally for 2 yr at 1 m resolution to describe the spatial heterogeneity of seagrass cover on the sites. We measured a number of environmental factors, including exposure to waves, tidal current speed, percent seagrass cover, sediment organic content and silt-clay content, seagrass shoot density, above- and belowground seagrass biomass, and numbers of bioturbation pits in the bottom. Seagrass bed cover ranged from 13 to 100% of the site, with 0 to 1.3% of the seafloor within the site showing discernable bioturbation pits. Three sites were selected for detailed study where we marked both existing bioturbation pits and new ones as they formed over time. Pits were measured every 1 to 3 d for width, length and depth until the pit was obscured; pit duration averaged similar to 5 d with an observed maximum of 31 d.

Its maximum lipid concentration of 67% of dry mass - consisting largely of wax esters - is the highest reported for freshwater zooplankton and is among the highest reported for marine polar species. The high lipid concentration of L. macrurus runs counter to the paradigm that high wax ester concentrations are found in herbivorous, but not in carnivorous, polar species. Lipids are drawn down to extremely low levels (10% of dry mass) during the reproductive period, November-May. Reproduction in this univoltine species appears to be timed so that the new generation develops during the high abundance of prey (crustacean microzooplankton and net phytoplankton) in spring. A high wax ester content may allow egg production to start in winter when the prey concentration is low. In contrast to many polar species, the new generation moves through all copepodid stages to adult without diapausing. Copepodid 5 females have a low lipid concentration, and lipids are slowly built up in new generation adults during summer and fall before reproduction commences. This lipid and life cycle strategy may have given L. macrurus an advantage over potential freshwater competitors, such as the arctic freshwater cyclopoid copepod Cyclops scutifer, in the hypolimnia of glaciated lakes.

ER - TY - JOUR T1 - Distributions and recent changes of carbon monoxide in the lower troposphere AN - 17103059; 4416974 AB - Since 1988, the distribution of carbon monoxide (CO) in the lower troposphere has been determined using a globally distributed air sampling network. Site locations range from 82 degree N to 90 degree S, with wide longitudinal coverage, and represent the marine boundary layer, regionally polluted atmospheres, and the free troposphere. In this paper, times series from 49 sites are discussed. With an average lifetime of similar to 2 months, CO showed significant concentration gradients. In the marine boundary layer, mixing ratios were greatest in the northern winter (200-220 ppb) and lowest in the southern summer (35-45 ppb). The interhemispheric gradient showed strong seasonality with a maximum difference between the high latitudes of the northern and southern hemispheres (160-180 ppb) in February and March and a minimum in July and August (10-20 ppb). Higher CO was found in regions near human development relative to those over more remote areas. The distributions provide additional evidence of the widespread pollution of the lower atmosphere. Remote areas in the high northern hemisphere are polluted by anthropogenic activities in the middle latitudes, and those in the southern hemisphere are heavily influenced by the burning of biomass in the tropics. While tropospheric concentrations of CO exhibit periods of increase and decrease, the globally averaged CO mixing ratio over the period from 1990 through 1995 decreased at a rate of approximately 2 ppb yr super(-1).

In this study, we examine how predation risk and food distribution interact to influence the schooling behavior and swimming speed of foraging juvenile walleye pollock, Theragra chalcogramma. Fish were acclimated to either spatially and temporally clumped, or spatially and temporally dispersed food for 3 weeks. Fish were then monitored while feeding in the absence and presence of predatory sablefish, Anoplopoma fimbria. Fish foraging for clumped food swam rapidly in a loose school when predators were absent, but swam more slowly and adopted more cohesive schooling in the presence of predators, trading-off foraging opportunity for decreased vulnerability to predators. Fish foraging for dispersed food swam about slowly and did not engage in cohesive schooling in either the absence or presence of predators. These fish accepted greater predation risk in order to continue foraging, suggesting that the cost of schooling, in terms of decreased foraging opportunity, was greater when food was dispersed than when it was clumped. This lower responsiveness to predators among fish receiving dispersed food demonstrates that predator avoidance does not always take precedence over other activities, but rather, that a balance is maintained between predator avoidance and feeding, which shifts as food distribution changes.

Our interest is focused primarily on ultimate wind loads, that is, loads that are sufficiently large to cause member failure. For non-hurricane regions (1) we comment on issues raised by the fact that directional data published by the National Weather Service are incomplete, and (2) note that, owing to the relatively small sizes of the data samples, results on directional effects for mean recurrence intervals longer than a few hundred years are inconclusive. For hurricane-prone regions we show that, on average, the common practice of disregarding wind directionality effects is conservative for 50-year wind loads. However, according to our results, the degree of conservatism decreases as the mean recurrence interval increases. While individual estimates of speeds with very long mean recurrence intervals are unreliable, statistics based on estimates obtained from large numbers of records can provide useful indications of average trends and suggest that, for mean recurrence intervals associated with ultimate wind loads, the favorable effect of wind directionality tends to be marginal.

As a contribution to the debate needed to achieve such a consensus, we describe an updated method for estimating wind loads that takes into account the directional dependence of the aerodynamic coefficients and the extreme wind climate, and uses the 'peaks over threshold' approach for the estimation of extremes. For hurricane-prone regions, assuming epistemic uncertainties are negligible, we estimate mean recurrence intervals (MRIs) of wind loads inducing the design strength, obtained from 50 yr loads via multiplication by a factor specified by the ASCE 7-95 Standard. For typical aerodynamic coefficients with strong directional preference, depending upon location and building orientation those estimated MRIs varied between less than 1000 to more than 10000 yr. If epistemic uncertainties were taken into account the estimated MRIs would be shorter. We also found that for loads with very large MRIs the common practice of disregarding direction effects is not necessarily conservative from a structural engineering viewpoint.

Distributions of radioactive isotopes are controlled mainly by the isotopic compositions of precursor molecules and radioactive decay processes. As a result, through their isotopic compositions, atmospheric species are traceable to sources and sinks. Thus, isotopic compositions provide useful information for estimating source strengths and for understanding the importance of removal processes in the cycling of the species. The use of radioactive super(14)C and the stable isotopes ( super(13)C and super(18)O) are reviewed here for understanding production and removal processes of CO in the troposphere. Carbon monoxide is a critical component in atmospheric chemistry because of its large effect on levels of OH, the principal oxidant in the atmosphere. In the troposphere, this is due to relatively high concentrations of CO and a short lifetime (2-4 months). Initially, super(14)CO measurements were instrumental in estimating accurately the tropospheric lifetime. Since seasonal super(14)CO variation is controlled largely by OH, super(14)CO serves as an important surrogate measure of tropospheric OH. Global super(14)CO measurements have also been used to estimate the biogenic component of the global CO budget, specifically contributions from biomass burning, oxidized non-methane hydrocarbon (NMHC) emissions, oceans and plants. Research using super(14)CO measurements is also active in quantifying fossil and non-fossil urban emissions. Kinetic isotopic fractionation during production of super(13)CO and C super(18)O from reduced precursors allows one to distinguish, at least qualitatively, different varieties of CO based on seasonal tropospheric isotopic measurements. Difficulties in interpreting the stable isotopic record arise from large fractionation effects that obscure source isotopic signatures (in particular the oxygen kinetic isotope effect for the CO + OH reaction), and large seasonal/latitudinal variability in source fluxes. While dual-isotopic CO source signatures do not allow a direct mathematical determination of contributions from several sources, plots of delta super(18)O vs delta super(13)C may help estimate relative proportions of dominant sources. In addition to understanding CO sources, the pressure dependence of the carbon kinetic isotope effect (KIE) has helped elucidate pathways for the CO + OH reaction. Since formaldehyde (HCHO) is an important intermediate in hydrocarbon oxidation to CO and CO sub(2), the stable carbon and oxygen isotopes in atmospheric HCHO may help distinguish different hydrocarbon sources to regional CO budgets and elucidate the importance of different oxidative reaction pathways.

AN - 16353185; 7015 AB - PURPOSE: The implementation of a comprehensive management program for the coastal zone associated with Lake Superior, located in northeastern Minnesota, is proposed. Lake Superior stretches approximately 350 miles west to east and 160 miles north to south and has a shoreline extending almost 2,800 miles. The lake drains 49,300 square miles, 89 percent of which is forested. The basin extends into Michigan, Minnesota, Wisconsin, and Ontario. Within the coastal area are 12 cities, 15 state parks, a national monument, portions of a national forest, two Indian reservations, and an international seaport. Numerous unincorporated settlements are scattered through the area, most of them hugging the coast. The approval of the program would allow administrative grants to be awarded to the state and require that federal actions be consistent with the program. Minnesota began the development of a coastal management program for the Lake Superior area in 1993. The coastal area as defined by the program's coastal boundary follows the nearest legal coastal township along the shore, or approximately six miles inland. In the metropolitan area around Duluth, the coastal area includes the cities of Duluth, Hermantown, Proctor, Carlton, Wrenshall, and Cloquet and all or parts of the adjacent townships; this area was determined to have the most significant impact on Lake Superior and its tributaries. The currently considered proposal would result in establishment of a 15- to 17-member Coastal Council through an executive order issued by the governor. Three persons from each of the four coastal counties would be chosen as council members. Three types of program organization are recognized through the national program as follows: direct permitting, where the leased state agency directly implements law(s) which regulate or manage coastal development; networked programming, where the lead state agency coordinates with other state and local agencies which together manage land and water uses and protect coastal resources; and local coastal programming, where the lead state agency works with local units of government to develop state approved local coastal programs. Minnesota has developed a networked program. Management policies would address coastal lands and waters, air and water quality, fish and wildlife, forests, mineral resources, energy, environmental review, development and economic revitalization plans, natural resource protection, recreation and water access, cultural resource protection, coastal nonpoint source pollution control, and federal coordination. Three Federal alternatives to program approval would include delaying or denying approval, if certain requirements of the Coastal Zone Management Act of 1972 had not been met. The state could modify parts of the program or withdraw its application for federal approval if either of the above-mentioned federal alternatives resulted from circulation of this draft EIS. POSITIVE IMPACTS: The approval and implementation of the program would enhance governance of Minnesota's coastal land and water uses according to the coastal policies and standards set out in Minnesota's statutes, authorities, and rules. Minnesota's Lake Superior Coastal Program would promote the beneficial use of coastal resources, prevent their impairment, and manage major activities that substantially affect numerous resources. The program would enhance decision-making processes used in determining the appropriateness of actions in the coastal area. NEGATIVE IMPACTS: NONE.

AN - 36405189; 7007 AB - PURPOSE: The amending the fishery management plan for the bluefish fishery in U.S. waters of the western Atlantic Ocean is proposed. All states along the Atlantic Seaboard would be affected. The goal of the management plan is to conserve the bluefish resource along the Atlantic coast. Major objectives adopted during scoping include increasing understanding of the stock and of the fishery; the provision of the highest availability of bluefish to U.S. fishing interests while maintaining, within limits, traditional uses of bluefish; provisions for cooperation among the coastal states, the various regional marine fishery management councils, and federal agencies involved along the coast to enhance the management of bluefish throughout the species' range; the prevention of recruitment overfishing; and the reduction of waste in both the commercial and recreational fisheries. Numerous alternative measures, falling within various categories, as well as a No Action Alternative, are considered in this draft EIS. The preferred alternative would be designed to rebuild the bluefish stock to minimum biomass threshold, which is specified as one-half the biomass level associated with the maximum sustainable yield over a nine-year rebuilding period. For the initial two years (1999-2000), fishing mortality would remain at the current level. Fishing mortality would be reduced by 10 percent during the ensuing three years and by a further 20 percent during the remainder of the rebuilding period. This schedule would allow for stock rebuilding to the level which would support harvests at or near maximum sustainable yield by the year 2007. Permit requirements would include operator permits for commercial and party and charter boats, vessel permits for party and charter boats, vessel permits for commercial vessels (permits to sell), and dealer permits (permits to purchase). Permitted individuals or vessels would be allowed to sell only to permitted dealers and permitted dealers would be allowed to purchase only from individuals and vessels permitted to sell. Party and charter boat operators, commercially permitted individuals, and dealers would be required to report regarding compliance with permit requirements. The plan would incorporate commercial fish size limitations and minimum mesh requirements, commercial quotas, de minimus specifications for quota allocation for states experiencing commercial landings of less than 0.1 percent of the total coastwide commercial landings in the last preceding year for which data was available, recreational size and possession limits as well as seasonal recreational limits and recreational harvest limits. A monitoring committee would review data on the fishery on an annual basis and submit recommendations to the management authorities regarding annual quotas, minimum take size, and minimum mesh size with respect to the commercial fishery and regarding possession and size limits and seasonal closures with respect to the recreational fishery. A framework adjustment process would be implemented to allow modification of management measures at any time during the year through a streamlined public review process. POSITIVE IMPACTS: The preferred alternative would eliminate overfishing and rebuild the bluefish stock through a graduated reduction in the fishing mortality rate. NEGATIVE IMPACTS: The quotas and other limitations set out in the amendment would cause economic hardships for some commercial operators.

Ozone laminae appear in the lower stratosphere soon after the polar vortex is established in autumn, increase in number throughout the winter and reach a maximum abundance in late winter or spring. We indicate a possible coupling between mid-winter, sudden stratospheric warmings (when the vortex is weakened or disrupted) and the abundance of ozone laminae using a 23-year record of ozonesonde data from the World Ozone Data Center in Canada combined with monthly-mean January polar temperatures at 30 hPa. Results are presented from an experiment conducted during the winter of 1994/95, in phase II of the Second European Stratospheric And Mid-latitude Experiment (SESAME), in which 93 ozone-enhanced laminae of polar origin observed by ozonesondes at different time and locations are linked by diabatic trajectories, enabling them to be probed twice or more. It is shown that, in general, ozone concentrations inside laminae fall progressively with time, mixing irreversibly with mid-latitude air on time-scales of a few weeks. A particular set of laminae which advected across Europe during mid February 1995 are examined in detail. These laminae were observed almost simultaneously at seven ozonesonde stations, providing information on their spatial scales. The development of these laminae has been modelled using the Contour Advection algorithm of Norton (1994), adding support to the concept that many laminae are extrusions of vortex air. Finally, a photochemical trajectory model is used to show that, if the air in the laminae is chemically activated, it will impact on mid-latitude ozone concentrations. An estimate is made of the potential number of ozone molecules lost each winter via this mechanism.

AN - 36402205; 7000 AB - PURPOSE: The construction of a two-lane road system on the island of Babeldaob in the Republic of Palau is proposed. The 127-square-mile island of Babeldaob is the largest island in the Palau archipelago and the second largest island in Micronesia. The island extends in a north-south direction for approximately 28 miles. The southern two-thirds of the island has an average width of eight miles, while the northern third consists of a narrow spur with an average width of one mile. The interior portion of the island is largely uninhabited partly due to limited access via land transportation systems. The existing roads connecting settlements on the island consist of dirt, gravel, or crushed coral surfaces. The major areas of concern addressed during scoping include political concerns of a sovereign nation, roadway engineering design parameters and safety factors, environmental concerns, cost considerations, and right-of-entry issues. Three alternatives are considered in this final EIS; the No Action Alternative was eliminated because it would fail to address existing practices and conditions which have a damaging effect on the environment. Under the preferred alternative, a loop system would be constructed in the southern two-thirds of the island and a single spur on the more narrow northern portion. The 52.2 miles of roadways would connect all ten states on the island and bypass existing settlements instead of running through them. Therefore, the roadway system would need to be complemented by secondary roads connecting to existing settlements. The construction of the roadway would be jointly funded by the U.S. government and the government of Palau. POSITIVE IMPACTS: Under the preferred alternative, the project would provide island-wide access to all settlements while minimizing disturbance to existing communities. The road would also provide access to areas with potential for agriculture, forestry, mining, industry, and tourism, and near watersheds for future water resource development, rock sources for quarries, and port development sites. The road would provide residents of the island an opportunity to live on their land and commute to work in Koror, rather than having to rent additional living quarters at or near Koror, as is now the practice. The project would generate 1,600 jobs per year in construction-related work and 3,088 indirect jobs. NEGATIVE IMPACTS: The economic development expected to result from roadway construction would gradually erode a traditional way of life. Land-disturbing activities could adversely affect geology and topography, soils, water quality, air quality, noise levels, flora, fauna, and coastal, marine, and estuarine resources. Traffic would increase as a result of specific developments (i.e., resorts) that would generate trip traffic in relative proportion to their scale of activities.

Based on multiplicative decomposition of expectation of rainfall into conditional expectation of rainfall given raining and probability of rainfall, the estimation procedures explicitly account for both within-storm variability of rainfall and variability due to fractional coverage of rainfall. As a result, in addition to the accuracy of radar rainfall data in estimating rainfall given that rainfall is successfully detected, that in discerning rainfall from no rainfall can also be taken into account. To evaluate the estimation procedures, cross validation was performed using hourly radar rainfall data from the Tulsa, Oklahoma, Weather Surveillance Radar-1988 Doppler version (WSR-88D) and hourly rain gage data under the radar umbrella.

AN - 36411631; 6985 AB - PURPOSE: The designation as a National Estuarine Research Reserve (NERR) of a site in the Guana, Tolomato, and Matanzas River area (GTM) of Florida is proposed. Currently, there are two NERRs in Florida, the 200,000-acre Apalachicola NERR and the 10,000-acre Rookery Bay NERR, both of which are on the Gulf Coast. Through Florida's land acquisition program, nearly 100,000 acres of additional land are available for NERR status. The GTM, part of the temperate Carolinian biogeographic province (East Florida subregion), is located south of Jacksonville on the northeast coast of Florida. The area consists of a system of bar-bounded estuaries extending south from Jacksonville to below Marineland behind the barrier island system. The portion of the GTM proposed for designation covers approximately 31,595 acres of publicly owned uplands, tidal wetlands, estuarine lagoons, and offshore areas. The area is geographically separated into a northern section associated with the Tolomato and Guana River estuaries, and a southern section associated with the Matanzas River estuary. The areas are separated by the populated areas of Saint Augustine, Saint Augustine Beach, and Crescent Beach. More specifically, the area includes areas south of the City of Saint Augustine (including the sovereign submerged lands within Class II waters of the Matanzas River and the sovereign submerged lands classified as outstanding Florida waters and adjoining publicly owned uplands within the Pellicer Creek Aquatic Preserve), the Faver-Dykes State Park, the Washington Oaks State Gardens, the Flagler County Princess Place Preserve, the Fort Mantanzas National Monument, and the Saint Johns River Water Management District Moses Creek Conservation Area and adjoining publicly owned conservation uplands and areas north of the City of Saint Augustine (including all sovereign submerged lands and other state-owned lands within the Guana River Marsh Aquatic Preserve), and the Stokes Landing Conservation Area. The administration of the GTM as an NERR would involve the designation of advisory groups, cooperating mangers, and a staff including a reserve manager, research coordinator, education coordinator, and resource management coordinator. The stewardship action plan, designed to facilitate government and citizen involvement, would involve the formation of partnerships with other agencies and organizations actively involved in resource protection in the GTM NERR watershed. Management direction for the NERR would also incorporate land acquisition programs, and action plans for public access, research monitoring, volunteer participation, facilities construction, and education, interpretation and public outreach. In addition to the two designated sites, eight sites on Florida's Atlantic Ocean coast are considered for nomination, and two alternative programs and a No Action alternative are also under consideration in this draft EIS. POSITIVE IMPACTS: The NERR designation and management would facilitate natural and cultural resource protection through long-term ecological research, environmental monitoring, environmental education, and resource stewardship. NEGATIVE IMPACTS: NONE. LEGAL MANDATES: Coastal Zone Management Act of 1972 (43 U.S.C. 1241).

AN - 36414577; 6981 AB - PURPOSE: The establishment and implementation of fishery management plans (FMPs) for calico scallops and sargassum habitat in the South Atlantic region by the South Atlantic Fishery Management Council is proposed. The management area encompasses areas within the United States' territorial waters and the Exclusive Economic Zone (EEZ) of Florida, Georgia, North Carolina, and South Carolina. This draft EIS considers five actions for the calico scallop fishery and four actions for sargassum habitat. The proposed action for the calico scallop fishery of the South Atlantic region would identify essential fish habitat (EFH) and establish EFH-habitat areas of particular concern (EFH-HAPCs) for calico scallops. It would also establish a FMP for the calico scallop fishery of the South Atlantic region. It would also prohibit the harvesting of calico scallops in the area bounded to the west by 80 degrees longitude, to the north by 28 degrees 30 minutes north latitude, to the south by 27 degrees 30 minutes north latitude, and to the east by the 100 fathom (600 feet) depth contour. It would also require the use of transponders by calico scallop vessels either in the South Atlantic EEZ or in the South Atlantic EEZ south of 28 degrees 30 minutes north latitude. The proposed action for sargussum habitat of the South Atlantic region would identify EFH and establish EFH-HAPCs for sargassum. It would also establish a FMP for sargassum habitat of the South Atlantic region. It would also prohibit the harvesting and/or the possession of pelagic sargassum in the South Atlantic EEZ. POSITIVE IMPACTS: The measures would allow for the continued development of sustainable fisheries that target both inshore and offshore fishery resources. Overfishing would be prevented through the use of effective management controls as the fishery develops. NEGATIVE IMPACTS: The use of transponders would meet with some resistance from industry groups due, in part, to the cost of installing the devices. Fishing operators harvesting in areas to be closed would suffer some economic losses. LEGAL MANDATES: Fishery Conservation and Management Act of 1996 (P.L. 104-208).

AN - 36413934; 6980 AB - PURPOSE: The amending of management regimes for various South Atlantic region fisheries by the South Atlantic Fishery Management Council is proposed. The management area encompasses areas within the United States' territorial waters and the Exclusive Economic Zone (EEZ) of Florida, Georgia, North Carolina, and South Carolina. This draft supplemental EIS considers amendments to the fishery management plans (FMPs) for shrimp, red drum, snapper grouper, coastal migratory pelagics, golden crab, spiny lobster, and coral, coral reefs, and live and hard bottom habitats of the South Atlantic region. Amendment 4 to the FMP for the shrimp fishery of the South Atlantic region would identify essential fish habitat (EFH) for penaeid and rock shrimp, and establish EFH-habitat areas of particular concern (EFH-HAPCs) for penaeid shrimp. It would also require the use of transponders by rock shrimp vessels fishing in the South Atlantic EEZ or in the South Atlantic EEZ south of 28 degrees 30 minutes north latitude. Amendment 1 to the FMP for the red drum fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for red drum. Amendment 10 to the FMP for the snapper grouper fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for species in the snapper grouper management unit. It would also prohibit all fishing within the experimental closed area. Amendment 10 to the FMP for the coastal migratory pelagics fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for coastal migratory pelagics. It would also prohibit fishing in the experimental closed area. Amendment 1 to the FMP for the golden crab fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for golden crab. Amendment 5 to the FMP for the spiny lobster fishery of the South Atlantic Region would identify EFH and establish EFH-HAPCs for spiny lobster. It would also prohibit fishing in the experimental closed area. Amendment 4 to the FMP for the coral, coral reefs, and live and hard bottom habitats of the South Atlantic Region would identify EFH and establish EFH-HAPCs for coral, coral reefs, and live and hard bottom habitats. It would also prohibit all fishing in the experimental closed area. It would also expand the Oculina Bank HAPC to an area bounded to the west by 80 degrees west longitude, to the north by 28 degrees 30 minutes north latitude, to the south by 27 degrees 30 minutes north latitude, and to the east by the 100 fathom (600 feet) depth contour. It would also expand the Oculina Bank HAPC by one to five miles on the western side between 27 degrees 30 minutes north latitude and 28 degrees 30 minutes north latitude. POSITIVE IMPACTS: The measures would allow for the continued development of sustainable fisheries that target both inshore and offshore fishery resources. Overfishing would be prevented through the use of effective management controls as the fishery develops.

AN - 62481448; ED421968 AB - Findings of this report indicate that, since an earlier 1994 study, the number of Americans that own computers has increased by over 50% and the number of households using e-mail has quadrupled. Nevertheless, access to the Information Superhighway is still beyond the grasp of many Americans. While the nation-wide telephone penetration rate remains at a relatively high level of 93.8%, some pockets of Americans still have no telephone service. Whites still have a far higher telephone penetration rate (95.9%) than Blacks (86.0%) and Hispanics (86.5%). There are even more disparities in computer ownership and access to online services. Although more Americans now own computers than before, households earning more than $75,000 are approximately seven times as likely to own a computer as those earning between $5,000 and $10,000. White households are still more than twice as likely (40.8%) to own a computer than Black households (19.3%) or Hispanic households (19.4%). These gaps in ownership levels are greater than they were three years ago. Findings underscore the importance of such programs as NTIA's Telecommunications and Information Infrastructure Assistance Program and the E-Rate (a program that will allow schools and libraries to establish Internet connections at discounted rates). Twenty-four charts illustrate statistics.

This hydrothermal helium signal is especially strong in the Pacific Ocean, where the spreading rate of the ridges is the greatest. In several areas of the Pacific the hydrothermal activity is of sufficient strength to produce intense helium plumes which clearly define the regional circulation. Among these are (1) a pair of helium plumes at 2500-m depth, which extend westward from the East Pacific Rise at 10 degrees N and 15 degrees S into the interior of the Pacific basin; (2) a helium plume at 2000-m depth extending southwest from sources on the Juan de Fuca Ridge in the northeast Pacific; and (3) a plume at 1100-m depth emanating from Loihi Seamount at 20 degrees N, which extends eastward from Hawaii to the coast of Mexico. The flow field implied by the helium distribution appears to be in reasonable agreement with Reid's [1997] steric height analysis for the Pacific. Copyright 1998 by the American Geophysical Union.

Part II: Inundation mapping using dynamic streamflow modelling AN - 18006468; 4756540 AB - Since the first River Forecast Centers of the National Weather Service (NWS) were established in the mid-1940s, hydrological forecasts of flood crests have been issued for a specific location (coincident with a stream gauge) at a given point on a river or stream. The forecasts typically extended for three days into the future or until an expected flood crest was reached. The forecasts were deterministic and future precipitation was assumed to be negligible from the time the forecast was issued until the time the crest was forecast to occur. Each flood forecast was related to a predetermined flood stage where damage would occur in the reach surrounding the forecast point. These forecast products were issued as single point values for an expected time when the crest might occur. The catchment areas affecting these forecast points were generally large, in the order of thousands of square kilometres. In later years, the number of hydrological forecast points increased and the hydrological (rainfall-runoff) forecast areas have become increasingly smaller, 500 to 1000 km super(2). End users of these forecasts have been seeking more detailed information, including probabilistic forecasts from days, to weeks, to months into the future. They are also asking for enhanced forecast information which provides additional information regarding the flow conditions between forecast points, especially within urban areas. In order to provide such enhanced forecast services the National Weather Service (NWS) is implementing an Advanced Hydrological Prediction System (AHPS) which has been under development for several years and was recently demonstrated.

Part I: Ensemble generated probabilistic forecasts AN - 17680158; 4756539 AB - Floods are the leading weather related hazard throughout the world. A review of the world's recent and prominent flooding events reminds us that major floods will continue to occur and are devastating. Preparedness for these events can lead to saving lives and property. Within the United States of America alone, floods cause an average of $3.6 billion in damages and 139 lost lives annually; over 75% of the Presidential disaster declarations for the USA are in response to flooding events. It is therefore important to make the mitigation of this hazard a high-priority task. The USA weather programme has been providing river and flood forecasts for the public since 1890. This programme is managed by the US Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), National Weather Service (NWS). Within the NWS, each of its 13 River Forecast Centers (RFCs) typically issue stage forecasts for only one, two and three days into the future at most forecast points and crest forecasts out to about one week for a few selected forecast points. These forecasts have been provided primarily for the protection of life and property in the vicinity of rivers. They have also been used for the assessment of extended drought scenarios. Droughts, while generally not life-threatening in the USA, have a serious impact on agriculture, ecosystems and water management, and the economy in general. This chapter, which is in two parts, describes an advanced real-time hydrological forecasting procedure which provides more accurate forecasts with long warning times. A significant feature of the system is its application of meteorological and climate (months to seasonal) predictions for the improvement of real-time hydrological forecasts. The system described was demonstrated operationally for the Des Moines River basin in March 1997.

N1 - Last updated - 2011-12-13 ER - TY - JOUR T1 - Recruitment of larval fishes into a North Carolina estuary during a bloom of the red tide dinoflagellate, Gymnodinium breve AN - 17160820; 4452222 AB - An unprecedented bloom of the toxic dinoflagellate Gymnodinium breve in coastal waters of North Carolina occurred during year three (fall-winter 1987-1988) of an eight-year larval fish study. This event was the basis for examining the possible effects of red tide on the estuarine recruitment of nine species of larval fishes. Densities of larvae for 1987-1988 were compared to their corresponding average densities for the two seasons prior to and five seasons after the red tide. Larval fish recruitment for most species over the entire 1987-1988 season was not unusually low, although two of nine species did exhibit their 8-yr minima during this time. Densities for 1987-1988 were compared with the densities averaged (by week) over the other 7 yrs and revealed three general patterns of response. Two species, Paralichthys albigutta (gulf flounder) and Citharichthys spilopterus (bay whiff) had consistently low densities throughout their normal period of recruitment, suggesting that their estuarine recruitment may have been impacted by the effects of G. breve even after the bloom ended. In contrast, Micropogonias undulatus (Atlantic croaker) and Lagodon rhomboides (pinfish) densities were generally normal, or above normal, both during the bloom and for the remainder of the larval recruitment season. Five other species (Brevoortia tyrannus, Atlantic menhaden; Paralichthys lethostigma, southern flounder; Leiostomus xanthurus, spot; Mugil cephalus, striped mullet; Myrophis punctatus, speckled worm eel) had low densities during the bloom, but increased markedly later in the season. This pattern suggested these five species suffered immediate effects when the red tide was extant, but had high recruitment success later in the season. In the first post-red tide year, six of the nine species had their highest mean catches over the first 14 wks of all 8 yrs and suggested a possible post-red tide beneficial effect on larval fish estuarine recruitment.

This is the first paper, however, to compare long-term toxicity of oil to a wide variety of phyla, using the same stable oil generation and analytical methods for comparison. We compare the 4- and 28-d sensitivities of 10 marine animals to the WSF of Cook Inlet crude oil. We also compare out results to published 4-d static bioassay values for the same species.

The results of a shipboard line-transect survey conducted in July-November 1991 ("summer") were compared to those from aerial line-transect surveys conducted in March-April 1991 and February-April 1992 ("winter"). Using a confidence-interval-based bootstrap procedure, abundance estimates for six of the eleven species included in the comparison exhibited significant ( alpha = 0.05) differences between the winter and summer surveys. Pacific white-sided dolphins (Lagenorhynchus obliquidens), Risso's dolphins (Grampus griseus), common dolphins (Delphinus spp.), and northern right whale dolphins (Lissodelphis borealis) were significantly more abundant in winter. The abundance of blue whales (Balaenoptera musculus) and gray whales (Eschrichtius robustus) reflected well-documented migratory patterns. Fin whales (B. physalus) were significantly more abundant during summer. No significant differences in seasonal abundance were identified for Dall's porpoises (Phocoenoides dalli), bottlenose dolphins (Tursiops truncatus), killer whales (Orcinus orca), sperm whales (Physeter macrocephalus), or humpback whales (Megaptera novaeangliae). Significant north/south shifts in distribution were found for Dall's porpoises, common dolphins, and Pacific white-sided dolphins, and significant inshore/offshore differences were identified for northern right whale dolphins and humpback whales.

In shipboard line-transect surveys binocular reticles are used to obtain estimates of radial distance from the ship to animals. From shore-based platforms both binocular reticles and theodolites are used to measure distances for determining spatial distributions and dive patterns of coastal animals. In aerial line-transect surveys inclinometers or angle markings on observation windows or wing struts are used to determine perpendicular distances from sightings to the trackline. In this note we present formulae which take into account the curvature of the earth for converting the angular readings from these instruments to the desired distance values. These formulae are then compared with approximations that have been used in the analysis of marine mammal survey data. The extent to which these approximations diverge from the distance formulae presented here is identified. The presented formulae have been used by researchers in marine mammal science in the past. The purpose of this note is to present them in the context of marine mammal surveys from various platforms.

The bluefish Pomatomus saltatrix is an oceanic spawner whose juvenile stages, upon entry into estuarine waters, become piscivorous and thereby experience greatly increased growth. Size attained during the growing season may therefore be determined by time of arrival into estuarine habitats. We exposed bluefish recently recruited to an estuary to three diet shift treatments in which test fish were fed adult brine shrimp Artemia sp. for 0, 10, or 20 d before they were switched to piscine prey. Bluefish that had a delayed onset of piscivory were smaller after 40 d of growth, indicating that they did not fully compensate for prior periods of slow growth. These bluefish did exhibit immediate moderate growth compensation (about 6% over 10 d) resulting from increased consumption rates, but relatively low growth efficiencies prevented full recovery of their growth losses. Low growth efficiencies may have resulted from an induced developmental handicap or an energetic penalty for prolonged feeding on an Artemia diet. The timing of age-0 bluefish recruitment into estuarine environments can have a lasting influence on size attained during the first growing season.

Tag-recovery data support a two-population hypothesis throughout the North American range: an Alaska population ranging from the Bering Sea, including the Aleutian Islands and extending down through the Gulf of Alaska to northwest Vancouver Island, Canada; and a west coast population extending from southwest Vancouver Island to Baja California. Tag recoveries indicate that these two populations mix off southwest Vancouver Island and northwest Washington, and to a lesser extent off southern Washington and Oregon. Alaska sablefish, which commonly migrate over 500 n mi, are more mobile than west coast sablefish. Tag recoveries for sablefish tagged in Alaska have shown strong mutual exchanges between nearly all areas. In contrast, west coast sablefish have shown far less migratory behavior. Tagging data with respect to bathymetry are difficult to interpret in both regions owing to the fact that tagging and recovery effort do not cover the full bathymetric range of adults. Results of analysis of tag-recapture growth data were consistent with patterns observed for several other pelagic and demersal species. That is, El Nino-Southern Ocean Oscillation events appeared to retard the growth of sablefish along the west coast and to enhance growth of Alaska sablefish. The timing of recoveries from sablefish tagged off Alaska and recovered off southwest Vancouver Island and Washington-Oregon suggests that movement south correlates positively with strong upwelling in this southern area. Although sablefish trap-index surveys show a north to south cline in the percentage of large sablefish (>60 cm, and possibly of Alaska origin) sampled in length frequencies along the west coast, we were unable to correlate annual fluctuations in these percentages with upwelling strength.

Tagging records were analyzed to determine the species composition, population structure, and seasonal occurrence of Kemp's ridley, Lepidochelys kempii, loggerhead, Caretta caretta, and green, Chelonia mydas, turtles. Additional information on local movements, morphometrics, growth, population estimation, and diet was provided for Kemp's ridley turtles. Subadult green turtles dominated the catch on the seagrass shoals of Waccasassa Reefs. Subadult Kemp's ridley turtles and, to a lesser degree, subadult and adult loggerhead turtles were primarily captured near the oyster bars of Corrigan Reef. Marine turtles were caught in these nearshore waters from April to November. Recaptures indicate that some Kemp's ridley turtles remain in the vicinity of Corrigan Reef during their seasonal occurrence and return to this foraging area annually. Seasonal and annual size distributions of Kemp's ridley turtles were investigated and regression equations were developed for carapace morphometrics. Carapace growth averaged 4-5 cm/yr for Kemp's ridley turtles, but growth analyses were confounded by the extrapolation of annual estimates from short-term recaptures. Population estimates for the Kemp's ridley mark-recapture data indicated a mean annual population size of 159 turtles at Corrigan Reef with presumably high rates of immigration and emigration by larger subadult turtles. Examination of fecal samples indicated that crabs were the primary food items of Kemp's ridley turtles captured near oyster bars.

Gag were randomly sampled from 1991 through 1993 (n=1398) and selectively sampled with a bias towards heavily pigmented fish in 1994 (n=648). All samples were taken from commercial and recreational fisheries in the northeastern Gulf of Mexico. Sex ratio was 49 females: 1 male for the 1991-93 samples. Heavily pigmented gag (n=62), commonly thought to be males, were collected from waters >41.0 m during all months except January and March. Of these, 60 were histologically sexed and found to be 5.0% female, 3.3% possibly early transitional male, and 91.7% male. Indeterminate spawning generally occurred from February through April in water depths >30.5 m. Hydrated oocytes were homogeneously distributed in hydrated ovaries. Shortest length and youngest age at spawning were 577 mm total length (TL) and 3 years for females, and 981 mm TL and 8 years for males. The highest batch fecundity (865,295 hydrated oocytes) occurred in an 8-year-old, 1038-mm-TL gag. Batch fecundity had a significant ( alpha =0.01) positive correlation with TL, gutted body weight, and age but was most strongly correlated with TL. Average annual spawning frequency ranged from 8 to 27 for 2- to 9-year-old fish, varying significantly by year (P<0.05) and among years and age classes (P<0.02). Annual fecundity estimates ranged from 0.065 to 61.4 million and correlated well with age.

Yellowfin sole were most concentrated nearshore; abundance gradually decreased with increasing bottom depth to trace numbers beyond 100 m. Male yellowfin sole were distributed nearer to shore than females in all years.. Proportions of males (no. males/no. both sexes), therefore, increased nearshore with decreasing bottom depth. Males outnumbered females by two to one in waters less than 30 m deep. Yellowfin sole during 1982-84 were distributed in deeper waters than during 1985-96. The shallower distributions after 1984 were attributed to greater percentages of mature fish that reside in nearshore spawning areas (3 million metric tons) during 1982-84 were attributed in part to increased availability of yellowfin sole within the standard survey area.

The purpose of this paper is to address the role of the large-scale flow on low-level cyclone/frontal structure and evolution through a combined observational and idealized modeling approach. Analyses of two observed cyclone cases embedded in large-scale diffluence and confluence, respectively, are presented to illustrate two possible cyclone/frontal structures and evolutions. Specifically, the cyclone moving into a diffluent, high-amplitude ridge becomes meridionally elongated and possesses a strong meridionally oriented cold front and a weak warm front. The cold front rotates into the warm front, forming an occluded front in the manner of the Norwegian cyclone model, as indicated by the narrowing of the thermal ridge connecting the warm sector to the cyclone center. In contrast, the cyclone moving into confluent, low-amplitude zonal flow becomes zonally elongated and possesses strong zonally oriented warm and bent-back fronts and a weak cold front. The frontal structure in this case is reminiscent of the Shapiro-Keyser cyclone model, exhibiting a fracture between perpendicularly oriented cold and warm fronts (i.e., the so-called frontal T-bone structure). The idealized simulations employ a nondivergent barotropic model in which potential temperature is treated as a passive tracer. When a circular vortex acts on an initially zonally oriented baroclinic zone, cold and warm fronts, a frontal fracture, a bent-back front, and eventually a Norwegian-like occlusion develop. When a circular vortex is placed in a diffluent background flow, the vortex and frontal zones become meridionally elongated, and the evolution resembles the Norwegian occlusion with a narrowing thermal ridge. When a circular vortex is placed in a confluent background flow, the vortex and frontal zones become zonally elongated, and the evolution resembles the Shapiro-Keyser model with a frontal fracture, frontal T-bone, and bent-back front. Although the idealized model qualitatively reproduces many of the frontal features found in the observed cyclones analyzed in the present study, one significant difference is that the maximum potential temperature gradient and fronto-genesis along the cold and warm fronts may differ by a factor of 2 or more in the observed cases, but remain equal along the cold and warm fronts throughout the idealized model simulations. Possible reasons for this asymmetry in the strength of the observed cold and warm fronts are discussed.

Forecast precipitation fields, although not perfect when compared to the observations of rainfall, appear to have sufficient information to be considered useful forecasting guidance. The results illustrate that a good simulation for this type of event in a region with complex topography is strongly dependent on a good initialization and prediction of the low-level flow and water vapor distribution. For two of the cases that have a marked synoptic-scale contribution, the simulations give reasonably accurate predictions of the precipitation distribution, although the amounts are generally underestimated. The third case exhibits relatively subtle synoptic-scale forcing and is dominated by isolated convective storms (mostly over the sea) that also produced severe thunderstorms (including tornadoes), and the prediction of precipitation is not as promising. Overall, the results are encouraging in terms of potential application of mesoscale models operationally in the western Mediterranean region. Additional experiments beyond the "control" simulations have been performed to isolate the influence of orography and water vapor flux from the Mediterranean Sea on the model simulations. This factor separation indicates that both effects can be important contributors to a successful forecast. Suggestions are offered for future efforts in pursuing the application of mesoscale models to this forecast problem.

The stomach contents of harbor porpoises killed in groundfish gill nets in the Gulf of Maine from September-December, 1989-94 were analyzed. Frequency of occurrence, numerical proportion, and proportion of ingested mass for Atlantic herring, pearlsides, silver hake, and red and white hake are reported. Calf diets differed significantly from those of adults in the number of herring eaten and the total mass of food eaten, but otherwise there were no major differences in diet by maturity or gender. Further studies are needed on seasonal shifts in harbor porpoise diets and movements to understand the causes of porpoise entanglement in gill nets and offer insight into potential mitigative measures.

Visual surveys conducted by divers from 1979-96 were used to estimate population abundance, assemblage composition, and stock structures in relation to habitat factors. An algorithm for calculating total mortality rates from exploitable phase fish average length estimates is explained. A reef fish equilibrium exploitation fishery simulation model was developed to take fishing mortality estimates as input and to generate yield-per-recruit data in relation to fishing intensity and gear selectivity, and spawning potential ratios in relation to federal overfishing standards. Some 23 species are below the 30% overfishing minimum. Depletion of the largest, most desirable, and most vulnerable reef fish species is typical of serial overfishing. Barracuda populations have grown during this period, suggesting major fish community structure changes.

A case study is described in which a wild dolphin was observed trailing a long, large clump of tangled fishing line wrapped around the tail flukes and peduncle. After several days, the dolphin permitted researchers to cut the line. Continued observation showed deep scarring, indicating that the flukes could have been severed had the line not been cut. Other research has documented entanglement in discarded monofilament line as a contributing factor in the death of several dolphins in the bay. The importance of mortality and serious injury to dolphins from recreational fisheries needs to be studied further.

The toxicity of OTC to elasmobranchs is unknown; if its effects on health and growth of treated fish is significant, its use as a chemical marker may be compromised. The effect of OTC treatment on the growth rate and health of captive nurse sharks were studied. Serologic and hematologic observations, as well as growth measurements and necropsies, indicated that growth rates between control and OTC groups were not significantly different. For the most part, serologic and hematologic chemistry also was not significantly different between the groups. OTC does not appear to produce short-term effects on nurse sharks that might complicate age validation. But minor evidence suggests potential hepatotoxic effects over long time periods.

Genetic variation in Chionoecetes bairdi and C. opilio in exploited populations in Alaska was studied to determine if enough differentiation exists to warrant re-examination of current management units. Allozyme electrophoresis data were used to estimate allele frequencies, average observed heterozygosities, and genotype frequencies, from which the degree of population subdivision was calculated. Low levels of geographic differentiation were found among populations of both species. Some of the data suggest that subpopulations of C. bairdi exist in the Bering Sea. Some gene transgression between C. bairdi and C. opilio also was observed.

Catch rates for the six most abundant species peaked in the early 1980s, declined by a factor of more than 100 to a low in 1984, and generally have remained low through 1993. One species has not been taken since 1984. Comparison of data from the King Harbor station with scuba transect data suggest that impingement data accurately reflect rockfish abundances in this area. Decreased recruitment success due to long-term adverse oceanographic conditions and overfishing probably are responsible for the drop in rockfish abundance.

Under high temperature hypoxic conditions, sturgeon survival declined to a mean of 6.3% and respiration rates dropped to a mean of 0.136 mg oxygen/g-h. Under low temperature hypoxia, survival was 78% and mean respiration rates were 0.212 mg O sub(2)/g-h. Growth rates diminished significantly under both conditions when sturgeon were denied access to the surface. Hypoxia probably has degraded sturgeon nursery habitats in Chesapeake Bay, preventing sustained recovery of sturgeon stocks.

The investigation of the variabilities and correlation of O sub(3) and CO presented here indicates that the seasonal cycles of the medians and the means of O sub(3) and CO are qualitatively similar to the cycles observed at other northern midlatitude sites. The signature of O sub(3) produced from anthropogenic precursors is clearest in the spring at the Azores and in the summer at Sable Island. The influence of the natural stratospheric O sub(3) source is apparent at Sable Island, particularly in the spring. At all sites the variability of CO throughout the year is dominated by episodes of pollution transport. The slopes of the monthly O sub(3)-CO correlations in the summer in Atlantic Canada and the spring in the Azores are quite uniform at 0.3 to 0.4. However, individual pollution transport events often have larger ( less than or equal to 1.0) slopes, which indicate significantly different net O sub(3) production efficiencies between episodes. The average slope of O sub(3) versus CO at Sable Island in the winter for moderate pollution transport events (CO less than or equal to 180 ppbv) is -0.28, which indicates that the titration of ambient O sub(3) by emitted NO with little if any photochemical O sub(3) production dominates the O sub(3) chemistry over eastern North America in winter. Diurnal cycles driven by photochemistry are observed in the summer for both O sub(3) and CO at the Azores (net loss) and Sable Island (net production.) These observations are consistent with the work of Duderstadt et al. who find positive net photochemical O sub(3) production at Sable Island, and with the modeling of Atherton et al. who find a region dominated by photochemical loss of O sub(3) and CO in the central Atlantic.

Collection and recovery efficiencies were found to be essentially quantitative for C sub(2)-C sub(7) hydrocarbons and better than 95 and 93% for methanol and formaldehyde, respectively. CO sub(2) prevented the measurement of the C sub(2) hydrocarbons in atmospheric samples, and system response to ambient water vapor limited the precision of the measurement at very low C sub(y). The measurement system had an estimated uncertainty of 10% at ambient mixing ratios of 100 ppb C, and a detection limit of between 5 and 7 ppb C. C sub(y) was measured in Boulder, Colorado, during June of 1993 and at Chebogue Point, Nova Scotia, during the North Atlantic Regional Experiment intensive campaign, August to September 1993. C sub(y) values ranged from several hundred ppb C to 11 ppb C in Boulder, and from 177 to below 5 ppb C at Chebogue Point, with medians of 55 and 11 ppbC, respectively. C sub(y) was found to correlate with both CO and O sub(3) at higher levels of those two pollutants. The sum of C sub(y) and the C sub(2) hydrocarbons was virtually always equal to or greater than the sum of the hydrocarbons. Several exceptions to this occurred when high HC values were observed in cannister samples but not C sub(y) measurements. These instances were attributed to short-term perturbations from local sources. There was a net difference between total nonmethane organic carbon and the sum of hydrocarbons and carbonyls of 3.5 plus or minus 7.8 ppb C overall. This difference appears to be broadly correlated with anthropogenic pollution. There does not appear to be a significantly large reservoir of reactive carbon unaccounted for by hydrocarbon or carbonyl measurements. JF - Journal of Geophysical Research. D.

The correlation of alkyl nitrates (RONO sub(2)) with carbon monoxide makes it clear that the chemistry at this site is being driven by continental emissions, since RONO sub(2) compounds are known to be by-products of HC-NO sub(x) photochemistry. Comparison of the ratios of alkyl nitrates to their parent hydrocarbons to that of 2-butyl nitrate/butane showed significant deviations from trends predicted from rate constants, branching ratios, and loss rates. For ethyl nitrate this deviation is likely due to a combination of many additional pathways to the intermediate peroxy radical from the decomposition of larger alkoxy radicals. The propyl nitrates showed trends that differed from one another; 2-propyl nitrate was a factor of 2 to 3 higher than predicted, while 1-propyl nitrate was a factor of 8 to 10 higher than predicted. The trend of 3-pentyl nitrate/pentane was relatively close (about 50% lower) to the predicted trend. The relationship between PAN and PPN showed unexpectedly high ratios of PPN to PAN in air masses coming from the south and west of the site, implying a slight local source of PPN.

The model is tested by comparisons of the results with observations obtained at two ground stations in Nova Scotia, Canada, and on board two aircraft. The modeled mixing ratios of CO and O sub(3) as well as the ratio of Delta O sub(3)/ Delta CO at the two ground sites are in satisfactory agreement with the observations. More than 90% of the aircraft-observed O sub(3) and CO and 75% of NO sub(y) can be reproduced by the model with relative differences less than 50 and 100%, respectively. The model-simulated correlations among O sub(3), CO, and NO sub(y) are close to the aircraft observations. Most of the model-calculated vertical distributions of these species have the same pattern as the observations. The calculated profiles coincide with the observations with mean discrepancies of about 25, 30, and 100% for O sub(3), CO, and NO sub(y), respectively. The model-calculated wind speeds are in good agreement with the observations. Continental plumes within the model may be spatially off by a few hundred kilometers or temporally off by several hours. Possible inaccuracy in side boundary conditions and some difficulties in capturing small scale processes like small scale intrusion from the stratosphere and subgrid scale convective mixing are possible explanations for discrepancies between chemical data and model results.

AN - 36413822; 6963 AB - PURPOSE: The implementation of a management plan for the Atlantic herring fishery by the New England Fishery Management Council is proposed. The management unit is defined as all Atlantic sea herring within United States territorial waters and the Exclusive Economic Zone (EEZ). The herring resource is under-exploited state. Estimated of current stock size are based on the most recent fully reviewed assessment, which estimated the 1994 three-plus biomass at a record level of 3.6 million metric tons (MT); the estimate for spawning stock biomass (SSB) was 2.1 million MT. The estimated maximum sustainable yield (MSY) for the Atlantic herring coastal stock complex is 317,000 MT (including the Canadian Georges Bank and New Brunswick harvests). Of this estimate, the Gulf of Maine (GOM) spawning component is believed to be capable of providing a long-term potential yield of 80,000 MT (including the New Brunswick juvenile catch). While these estimates of large exploitable biomass have increased commercial interest in the development of the herring fishery, there are concerns that specific spawning components (notably the GOM component may not be able to sustain current or increased fishing pressure over the long-term. The maximum fishing mortality established by the plan is F=0.30. The minimum biomass level is established as 50 percent of the biomass at MSY (approximately 500,000 MT). The management plan would establish a target fishing mortality of 0.28 when total biomass exceeded biomass at MSY. When biomass fell below biomass at MSY, the target fishing mortality would be based on a five- to ten-year rebuilding schedule. Several alternatives, including a No Action alternative, are considered in this draft EIS. Management measures considered would include the adoption of a total allowable catch (TAC) and the distribution of the TAC across time and area, the closure of the fishery in an area when the TAC was reached, effort controls to limit catches as a TAC was approached, a requirement that licensed vessels and dealers be subject to mandatory data reporting, the implementation of effort controls, restrictions on the size of vessels allowed in the fishery, a series of spawning area restrictions, options for a controlled access system, restrictions on the use of herring, possible restrictions on joint venture processing activities, and a permit system for all participating vessels, operators, and dealers. POSITIVE IMPACTS: The measures would allow for the orderly development of a sustainable fishery that targets both the inshore and offshore herring resource. Overfishing would be prevented through the use of effective management controls as the fishery develops. An annual scientific review of the status of the resource would allow for adjustments to the fishery as a result of fluctuations in stock size. NEGATIVE IMPACTS: Some objectives could prove to be economically incompatible. Spawning area restrictions would increase fishing costs and reduce the value (fat content) of fish taken, as it is during spawning that fish aggregate and contain the greatest fat volume.

AN - 36411321; 6962 AB - PURPOSE: The amending of the management plan for the sea scallop fishery of the Atlantic Ocean by the New England Fishery Management Council is proposed. The management unit consists of sea scallop resources from the shoreline to the outer boundary of the Exclusive Economic Zone (EEZ). The overall objectives of the original management plan, implemented in May 1982, are to restore adult sea scallop stock abundance and age distribution; to increase yield per recruit for each stock; to evaluate plan research, development, and enforcement costs; and to minimize adverse environmental impacts on sea scallops. This draft supplement to the final EIS of May 1982 considers changes to the way Atlantic sea scallops are managed. The objective is to reduce fishing mortality in the EEZ to prevent overfishing of scallops and to rebuild the Atlantic scallop stocks to a level that will produce the maximum sustainable yield on a continuing basis. Alternatives with seven- and ten-year time frames are under consideration along with the continuation of the current regime (the No Action Alternative). Each time frame would incorporate different annual fishing mortality targets. Under the preferred alternative (a ten-year schedule), substantial reductions in fishing would be enforced. In addition to the analysis of the time frames for the rebuilding program, this draft supplemental EIS presents four management options for achieving the fishing mortality reduction targets. Management options would include a reduction in the number of days-at-sea (DAS) for the limited access scallop fishery, the closure of areas, bycatch reduction measures, and other measures that would be implemented through the framework adjustments process. All options would specify DAS limits. Option A would specify no measures designed to increase the size of scallops caught. Option B would substitute areas closures for 25 percent of the annual DAS reductions. Option C would enforce additional measures to increase the size of scallops caught (partial recruitment) to larger than 90 millimeters (mm) in shell height by the year 2006. Option D would enforce additional measures to increase the size of scallops caught to larger than 90 mm in shell height by the year 2000. The Council could implement any of these options, but any measures requiring additional area closures or opening any part of the groundfish areas closed to scallop fishing would have to be implemented through a framework adjustment after the plan was approved. In other words, the DAS reductions would constitute the only measures that could be implemented under any of these options until the Council submits a framework adjustment that included the other measures under Option B, Option C or Option D. POSITIVE IMPACTS: The amendment would reduce the current rate of fishing mortality, which is unacceptably high, and provide for flexibility in dealing with dynamic fishery conditions. NEGATIVE IMPACTS: The imposition of DAS and other controls would restrict the immediate commercial capacity of the fishery, causing short-term economic hardships for some users. Some jobs would be lost if vessels excluded from the scallop fishery did not switch to an unregulated species. The preferred alternative would result in lower calculated net economic benefits than the other action alternative considered.

A version of the RELMAP mercury model is used which separately simulates the transport and deposition of emissions from the seven point-source categories modeled. A mercury air emission inventory developed by the U.S. EPA Office of Air Quality Planning and Standards for the continental United States is used. This inventory provides estimates of the total mercury mass emitted, but does not define the chemical and physical forms of these emissions. A wide variety of emission speciations, combinations of chemical and physical forms, are evaluated with the new RELMAP mercury model. Average annual concentrations and wet and dry deposition totals are simulated for a complete calendar year. The results of the simulation are used to estimate the quantity of mercury deposited to soils and water bodies based on a variety of assumed emission speciation for the seven point-source types. An analysis of the modeling results provides some quantitative information about the sensitivity of modeling results to uncertainty in the mercury emissions speciation of modeled industrial activities, but a qualitative assessment is the primary goal. The model is shown to be most sensitive to mercury emissions speciation uncertainty related to the burning of waste materials and electrical power generation.

AN - 36416866; 6941 AB - PURPOSE: The production of oil by BP Exploration (Alaska) Inc. (BPXA) from the Northstar Unit offshore of the Point Storkersen area in the Alaskan Beaufort Sea is proposed. BPXA's action would involve a self-contained offshore development and production facility located on a gravel island in 39 feet of water. Five alternatives, including a No Action Alternative (Alternative 1), are considered in this draft EIS. Under BPXA's proposed action (Alternative 2), the island would be constructed over the remains of Seal Island, built by Shell Oil Company to conduct exploratory activities within the Northstar Unit during the 1980s. Two pipelines buried in a single trench, extending from Seal Island to existing onshore facilities, would transport hydrocarbons to and from the Northstar Unit. The pipelines include a 10-inch common carrier pipeline from Seal Island to Pump Station Number 1 to transport sales quality oil to the Trans-Alaska Pipeline System and a second 10-inch pipeline to transport high-pressure gas from the Central Compressor Plant in the Prudhoe Bay Unit to Seal Island to assist with the gas cycling process used to deplete the Northstar reservoir. BPXA determined that the Northstar Unit contains approximately 145 million barrels of recoverable, high quality crude oil. The production facilities on Seal Island would be designed to produce up to 65,000 barrels of crude oil and 500 million standard cubic feet of natural gas per day. The facilities would include 15 producing wells, seven gas injection wells, and either one or two Class I waste disposal wells. Approximately 700 to 800 tankers trips per year departing the Valdez marine terminal are required to accommodate current North Slope production; the production of reserves from the Northstar reservoir would require the operation of additional tankers from the Valdez terminal. Over the life of the project, approximately 181 to 198 additional tanker trips would be required. All of the action alternatives would include the same offshore development and production facility; the differences distinguishing the action alternatives involve routing and other aspects of the pipeline system. The preferred alternative (Alternative 5) would use a pipeline buried within a causeway rather than a trench and a landfall at West Dock. The Northstar project would be the first offshore oil and gas development and production facility in the Alaskan Beaufort Sea without a causeway to shore and the first to include a connection to onshore facilities by a buried subsea pipeline. The risks of oil spills from the offshore island and the pipeline system exposed to ice hazards demanded in-depth analysis. Moreover, response limitations for oil spills under sea ice or in broken ice, and concerns regarding effects of such spills, also required attention. Finally, the effects of long-term year-round offshore oil and gas development and production activities, particularly noise emissions, are of particular concern with respect to their impact on subsistence activities. The life of the Northstar Unit development would extend approximately 15 years. POSITIVE IMPACTS: Oil produced by the Northstar Unit would help satisfy meet national energy requirements, and the development and production activities would employ 730 workers during construction and 25 workers during the life of the project. The project would contribute $520 million in gross state revenues. NEGATIVE IMPACTS: Alternative 5 would result in 3.1 miles of onshore pipeline on currently undeveloped land. Helicopter maintenance of the pipeline would disturb wildlife, particularly brand nesting areas. Noise and activity associated with the operation of the Seal Island facility, and related vessel transport operations, could result in bowhead whale avoidance response during migration periods, potentially adversely affecting subsistence hunting activities. The project facilities would mar area aesthetics. Alternative 5 would present a risk of 19 percent of a large oil spill (greater than 1,000 barrels).

AN - 36395079; 6940 AB - PURPOSE: The establishment of a Marine Conservation District (MCD) in association with the fishery management plan (FMP) for corals and reef-associated plants and invertebrates in the waters of Puerto Rico and the U.S. Virgin Islands is proposed. Coral reefs are among the most productive tropical marine systems, and form the backbone of the ecosystem's food chain. The existing FMP, established in 1996 by the Caribbean Fishery Management Council (CFMC), was prepared to establish a management system for coral reef resources within the Exclusive Economic Zone (EEZ) and the waters under the authority of the Commonwealth of Puerto Rico and the Territory of the U.S. Virgin Islands from the shoreline to the edge of the insular platform. It prohibits the harvest or possession of stony corals, sea fans, gorgonians, or any species in the fishery management unit if attached to, or existing upon life rock; prohibits sale of possession of any prohibited species unless imported and fully documented as to the point of origin outside the EEZ, prohibits the use of chemicals, plants or plant derived toxins, or explosives for harvest; and restricts harvesting of other invertebrates to dip nets, slurp guns, hand capture or other non-habitat descriptive methods. Presently, the CFMC is proposing the MCD, a measure that was reserved under the FMP; the MCD would be located in EEZ waters surrounding the Virgin Islands. An MCD is a discrete geographical area of special value and significance to the marine ecosystem that is to be maintained in its natural state. The purpose of the MCD is to conserve and manage representative samples of marine habitats and ecosystems and to maintain marine biodiversity. In addition, MCDs are established for the protection, conservation and arrangement of economically important species. The criteria for determining the geographic location of an MCD include ecological values (diversity of species, endangered species habitat, uniqueness of the area, representative ecosystem, importance to commercial species, and maintenance of natural areas), economic values (traditional fishery location, snorkel and dive opportunities, charter boat anchorage opportunities, attractiveness to tourists, and watershed management), and social values (cultural significance, recreational value, aesthetics, educational opportunities, and research opportunities). Alternatives under consideration include three options, the establishment of a no-take MCD in the area known as Hind Bank southwest of Saint Thomas (Option A and Option B), the establishment of a no-take MCD due south of Saint John (Option C), and a No Action Alternative (Alternative D). POSITIVE IMPACTS: The MCD establishment would provide refuge and replenishment areas to ensure continued abundance and diversity of reef resources; protect critical spawning stock and recruits from depletion and overfishing, thereby increasing the abundance of fishery resources; protect coral and coral habitat; and improve opportunities for eco-tourism. NEGATIVE IMPACTS: Certain individuals engaged in the harvesting and sale of commercially-important fish species would be adversely affected in the short-term.

Research into future climate change and the development of remedial environmental policies therefore require a reliable assessment of the long-term growth rate in the atmospheric methane load. Measurements have revealed that although the global atmospheric methane burden continues to increase with significant interannual variability, the overall rate of increase has slowed. Here we present an analysis of methane measurements from a global air sampling network that suggests that, assuming constant OH concentration, global annual methane emissions have remained nearly constant during the period 1984-96, and that the decreasing growth rate in atmospheric methane reflects the approach to a steady state on a timescale comparable to methane's atmospheric lifetime. If the global methane sources and OH concentration continue to remain constant, we expect average methane mixing ratios to increase slowly from today's 1,730 nmol/mol to similar to 1,800 nmol/mol, with little change in the contribution of methane to the greenhouse effect.

AN - 73913788; 9747518 AB - Since their invasion into the Great Lakes, zebra mussels, Dreissena polymorpha, have increased the water clarity in Lake St. Clair and Lake Erie due to their extensive particle filtration. Because these particles contain sorbed contaminants, the potential for contaminant accumulation from both suspended sediment and algae were examined. Sediment or algae were dosed with selected radiolabeled polycyclic aromatic hydrocarbon congeners and/or hexachlorobiphenyl (HCBP). Assimilation efficiencies were measured and depended on food quality. Zebra mussels, 17 +/- 2 mm long, assimilated 58.3 +/- 13.5% of the pyrene and 44.7 +/- 5.8% of the benzo(a)pyrene (BaP) from sediment particles with a particle clearance rate of 493-897 ml/g tissue/h. However, assimilation efficiencies were 91.7 +/- 3.7% for pyrene, 91.9 +/- 1.4% for BaP, 96.6 +/- 1.4% for chrysene, and 97.7 +/- 0.5% for HCBP from suspended algae. Algal particle clearance rates for the mussels ranged from 47-143 ml/g tissue/h. Thus, zebra mussels efficiently accumulated non-polar contaminants sorbed to algae, while a smaller fraction of the sediment-associated contaminant was bioavailable. Furthermore, the contaminants sorbed onto suspended sediment particles were quickly removed from the water and deposited as pseudofeces.

However, the aftershock area of the earthquake is not only in the Delarof segment but also in the Andreanof segment where the 1986 Andreanof earthquake occurred previously. We estimate the fault parameters of the 1996 earthquake by numerically computing the tsunami and comparing the waveforms with that recorded at Adak. The fault width is 30 km or less, and the average slip is about 4 m. The observed far-field tsunamis around the Pacific are also explained by the synthetic tsunami computed using the above fault parameters. The results indicate that the 1996 earthquake ruptured parts of both the Delarof and Andreanof segments. However, the 1996 earthquake did not rupture the region of the largest moment release by the 1986 earthquake. Copyright 1998 by the American Geophysical Union.

Removing the time-varying part of the field is a task of data reduction, and the most common time variation is the quiet daily variation, S (sub q) . It is thus valuable to have for reference type curves of the quiet daily variation in the total field. To meet this need, global data obtained during the 1965 International Year of the Quiet Sun have been used to derive type curves describing the S (sub q) variation of the total magnetic field, in addition to the traditional field components. As for the traditional components, the total-field curves show significant seasonal and latitudinal variability in amplitude and phase. The effect of the equatorial electro-jet is clearly evident. In both hemispheres of the globe there are bands of reduced amplitude in total-field signal between the equator and the path of the S (sub q) focus. These bands, here termed the total-field "doldrums", persist throughout the year. Copyright 1998 by the American Geophysical Union.

Synoptic measures of sediment contamination, toxicity, and macroinfaunal condition were made at 82 and 86 stations in 1994 and 1995, respectively, in accordance with a probabilistic sampling design. These data were used to estimate percentages of degraded vs. undegraded estuarine area from the perspective of sediment quality. Each year a sizable portion of the province (36% in 1994, 51% in 1995) showed some evidence of either degraded benthic assemblages, contaminated sediments in excess of bioeffect guidelines, or significant sediment toxicity (based on Ampelisca abdita and Microtox registered assays). However, co-occurrences of a degraded benthos and adverse exposure conditions (sediment contamination and/or toxicity) were much less extensive -- 17% of the province in 1994 and 25% in 1995. Each year only four sites, representing 5% of the province in 1994 and 8% in 1995, had degraded infauna accompanied by both sediment contamination and toxicity, suggesting that strong contaminant-induced effects on the benthos (based on such combined weight-of-evidence) were limited to a fairly small percentage of estuarine area province-wide. PCBs and pesticides (lindane, dieldrin, DDT and derivatives) were the most dominant contaminants over the two-year period. The broad-scale sampling design of EMAP was not intended to support detailed characterizations of potential pollutant impacts within individual estuaries. Thus, some estuaries classified as undegraded may include additional degraded portions outside the immediate vicinity of randomly sampled sites. Such localized impacts (not accounted for in the above estimates) were detected in this study at additional nonrandom supplemental sites near potential contaminant sources.

This involved, first, a petition from John Churchman for protection of an invention for determination of longitude using magnetic variation, and second, a request for congressional support for a voyage to Baffin's Bay to determine the cause of the magnetic variation. The discussions and arguments are an instructive introduction to those that arise when Congress considers scientific projects. The new government came into being after ratification by the requisite nine states.

All species' identities determined by a combination of selective media, beta -hemolysis, and biochemical fermentation profiles were confirmed by PCR, with one exception. One strain (4-4), previously identified as L. innocua because of the lack of hemolysis on blood agar, was shown to be L. monocytogenes. In order to determine whether this isolate was a weakly hemolytic variant and thus potentially virulent, or whether it was truly unable to express listeriolysin (LLO), a number of phenotypic and genetic characterizations were performed. The strain was competent for expression of other L. monocytogenes virulence factors and characteristics such as the phosphatidylinositol-specific phospholipase C and the ability to adhere to and invade Caco-2 and J774 cells, but could not grow intracellularly and was avirulent in mice. DNA sequencing of the LLO gene (hly) from strain 4-4 showed that the genetic lesion was a single base-pair deletion, resulting in a frame-shift and subsequent stop codon in the translated open reading frame. Such a mutation is unique from those seen in previously described naturally occurring non-hemolytic L. monocytogenes strains.

Under a 12 h light/12 h dark photoperiod, juveniles displayed a diurnal shoaling and activity pattern, characterized by fish swimming in cohesive groups during the day, with a cessation of shoaling and decreased swimming speeds at night. Prior studies of schooling fishes have demonstrated distinct light thresholds below which schooling abruptly ceases. To see if this threshold effect occurs in a predominantly shoaling species, like juvenile walleye pollock, another experiment was undertaken in which illumination was lowered by orders of magnitude, giving fish 20 min to adapt to each light intensity. Juvenile walleye pollock were not characterized by a distinct light threshold for shoaling; groups gradually dispersed as light levels decreased and gradually recoalesced as light levels increased. At light levels below 2.8 x 10 super(-6) mu E s super(-1) m super(-2), juvenile walleye pollock were so dispersed as to no longer constitute a shoal. Exposure to simulated predation risk had differing effects upon fish behavior under light and dark conditions. Brief exposure to a model predator in the dark caused fish to swim faster, for 5 or 6 min, than fish which had been similarly startled in the light. Chronic exposure to a living predator produced similar results; fish tended to swim slower when a predator was present in the light, but faster when a predator was present in the dark. In the light, shoaling and/or schooling provide protection against predators. But in the dark, with fish unable to see one another, increased prey activity resulting from predator disturbance may lead to accelerated dispersal of prey shoals. Thus, perceived predation risk may have different effects upon the spatial distribution of juvenile walleye pollock under light and dark conditions. This has implications for survival, as fish which have become widely scattered during the darkness may take longer to reform shoals at dawn, resulting in greater predation risk.

One hundred 1 d old glaucothoe were placed into each of 3 replicate 10 l aquaria, each containing a choice of 3 substrates: sand, gravel, or synthetic fiber mesh. Glaucothoe began settling on the first day, and <10% remained swimming after Day 6. Glaucothoe showed a significant preference for the structurally complex mesh substrate. Occupancy of mesh increased from 49% on Day 2 to 75% by metamorphosis to the first crab (C1) instar, with a mean of 62 plus or minus 11%, Glaucothoe rejected sand, and only 1% were observed on it. Settlement was also tested in aquaria with only sand, gravel or mesh substrates. Glaucothoe in gravel- or mesh-only aquaria settled rapidly, whereas 40% of glaucothoe in the sand-only aquarium continued swimming until metamorphosis to C1 instar. In addition, mean time-to-metamorphosis in the sand-only aquarium (17.6 d) was significantly greater than in other experimental aquaria (16.8 d). Glaucothoe in the sand-only aquarium exhibited marked diurnal swimming behavior; 66% were swimming at 14:00 h (vs a maximum of 12% in other aquaria), but only 5% (vs 1%) were swimming at 02:00 h. Daytime swimming probably allows glaucothoe to avoid nocturnal predators while searching for preferred substrates, i.e. those which are structurally complex, can be easily grasped, and provide a high degree of interstitial space.

Pollution may be one of these factors. Sediments in estuaries are known to act as repositories for contaminants, and estuaries are important habitats for ocean- and river-migrating salmon. We have shown that juvenile salmon Oncorhynchus spp. and their prey bioaccumulate chlorinated hydrocarbons and aromatic hydrocarbons--important classes of toxic xenobiotics. Furthermore, we have shown that exposure to these pollutants can lead to immunosuppression and increased disease susceptibility in juvenile salmon. Whether pollution influences natural disease outbreaks in host populations, including salmon, is currently unknown. It is postulated that the occurrence of disease depends on the interaction of the host, the environment, and the pathogen. Absence of pathogens would reduce the potential for adverse environments to influence disease outbreaks. However, a recent reconnaissance survey of juvenile chinook salmon Oncorhynchus tshawytscha from Oregon coastal rivers revealed that pathogens were an integral component in all systems studied, although the prevalence of the pathogens varied. Furthermore, recent studies of natural fish populations have demonstrated that infectious-disease-induced mortality can significantly reduce the size of the host population. By creating adverse environments (e.g., polluted estuaries) which alter the susceptibility of the host to pathogens that are integral and ubiquitous components of the habitat, pollution increases the probability of disease-related impacts on fish populations.

The system was designed to interrogate previously PIT tagged juvenile salmonids migrating down the Columbia River without interfering with the traditional subsampling of fish passing through the facility. In addition, the design enables fish of virtually any size, and debris, to pass over the system's antennas without the port restrictions imposed by traditional pass-through PIT tag interrogation systems. We describe the fish facility in addition to the flat-plate system and its operation. The system tag reading efficiency was evaluated during 1996 and 1997 using a direct method based on the release of known numbers of tagged test fish and an indirect statistical procedure based on tagged run-at-large fish. The results showed that PIT tag reading efficiency during both years using the direct method averaged 97%, while that using the statistical procedure averaged 99% for the dual multiplexed antenna array. During the 1996 and 1997 field seasons 4371 and 14733 fish, respectively, were recorded.

Although drought is a naturally-occurring phenomenon throughout most parts of the world, the effects of drought on water resources and agricultural production have tremendous repercussions on the physical, economic, social, and political elements of our society, and rank with the most severe hazards in terms of monetary losses. The drought of 1987-89, although not the worst in history, was the most recent severe drought in the U.S., resulting in $15 billion in crop losses. Agriculturally important areas such as the Great Plains remain extremely vulnerable to drought in spite of advances in long-term weather forecasting and agricultural technology. Historically, this region has been hit hard by the disastrous droughts of the 1930s and 1950s, and global change predictions suggest this area will experience warmer and drier conditions with increases in atmospheric CO sub(2).

Near-real time data values will be collected, processed and delivered among the participants. The flow of data will be maintained as a dynamic process from a series of underwater sites and then distributed to the community. Project ACCESS is being constructed to maintain an ocean monitoring network which measures the fundamental parameters of ocean temperature, salinity, the velocity profile, turbidity, visibility, surface velocities and the wind field at each of the nodes of the network. A grid of nodes will be determined from the requirements of the infrastructure community that receives the data from the monitoring sites and executes the mission of the organization based in part on these values.

We tested the effects of site, planting density, water depth, and fertilizer addition on survival and growth through June 1996. Temperature, salinity, light transmittance, turbidity, and sediment properties at two restoration sites, Redfish Cove and Snake Island Cove, were similar to those in naturally occurring grassbeds in nearby Christmas Bay. Halodule survival, coverage, and new shoot densities were affected by site (significantly higher at Redfish Cove than at Snake Island Cove, which eventually failed), by planting density (significantly higher when planted on 0.25-m or 0.5-m centers rather than on 1.0-m centers), and by water depth (significantly higher when planted in relatively shallow water). Propagation (spreading from transplant units) was significantly greater from 0.25-m or 0.5-m center plantings but was not consistently affected by site or water depth. Fertilizer enhanced propagation but not survival. After two years, Redfish Cove produced belowground biomass similar to that observed in Christmas Bay, but aboveground biomass remained significantly less. Snake Island Cove plant mortality in September 1995 may have been presaged by low root-rhizome carbohydrate levels observed in October 1994, but causes remain unknown. Further restoration of Halodule to Glaveston Bay is possible at selected sites, but structural equivalency will take longer than two growing seasons to achieve.

A conspicuous pattern is alternating warm and cool periods of several years' duration. These variations in sea ice cover are reflected in the character of a subsurface cold pool, formed as stratification isolates the deeper cold waters from surface exchanges. The cold pool is better developed and more extensive in summers that follow deep southward penetration of winter sea ice. Interannual and decadal-scale variations in the distributions of some fish stocks reflect those of ice and thermal conditions. In particular, the distribution of walleye pollock, Theragra chalcogramma, varies significantly with multiannual cool and warm years while Arctic cod, Boreogadus saida, is only present within the cold pool. The relation among climate variations, sea ice cover, subsurface thermal conditions, and fish distribution provides information on how climate affects marine ecosystems and may also have practical application in predicting fish distributions.

Therefore, when I wrote the paper outlining the concept of evolutionarily significant units (ESUs) for identifying "distinct population segments" of Pacific salmon (Oncorhynchus spp.) under the U.S. Endangered Species Act (ESA), I realized that any attempt to identify conservation units below the species level would also generate a good deal of scientific discussion. This has proved to be the case. At the same time, a parallel discussion has taken place of which the primary focus is not biological issues but rather the degree to which the ESU concept satisfies the original intent of the U.S. Congress and the ESA itself. The recent essay in these pages by Pennock and Dimmick (1997) follows in this tradition. Pennock and Dimmick argue that the ESU concept adopted as policy by the National Marine Fisheries Service for identifying distinct population segments of Pacific salmon under the ESA (1) is inconsistent with the original intent of Congress, (2) unduly narrows the scope of populations that can be considered distinct under the ESA, and (3) limits flexibility under the ESA. The comments below address these criticisms as they apply to the NMFS ESU policy for salmon.

Marine reserves could potentially deal with many fishery problems that are not effectively addressed by other traditional management measures; they also offer numerous social, economic, and scientific benefits not directly related to fisheries. Limited but growing research has shown beneficial biological and economic effects of marine reserves on fisheries. More research is needed, especially at larger scales, to determine the ideal marine reserve size, number and location necessary to optimize fisheries productivity and resource conservation. Sufficient evidence is available to justify the expanded use of marine reserves in an adaptive approach to fisheries management.

AN - 16484200; 4365821 AB - 'Ecologic' reef fishes (basic research subjects) and 'Economic' reef fishes (exploited by humans) share fundamental early life-history attributes of small, widely dispersed planktonic eggs, larvae, and (for some species in both groups) pelagic juveniles. These attributes predispose the open populations of species in both groups to limitation resulting from environmentally induced fluctuations in recruitment from planktonic/pelagic to benthic stages. Rates of movement within and among reefs, one of several postrecruitment processes likely to be subject to density-dependent regulation, may differ between Ecologics (mostly small-bodied) and Economics (generally larger-bodied). This is because of differences between species in the two groups in size-related differences in the home ranges of individuals. Existing data, however, neither support the notion that natural growth and mortality rates basically differ between the adults of Ecological and Economic species, nor that the generally larger home ranges of larger-bodied adult Economics are more subject to density-dependent control. Further, the small-bodied young-of-year juveniles of both groups on average probably have similar growth and mortality rates and small individual home ranges that are equivalently affected by density dependence. In conclusion I argue that, because of fundamental similarities in the sizes and durations of planktonic propagules and spawning periodicities, certain Ecologics and Economics may comprise a single recruitment guild. Coefficients of growth and mortality for postsettlement Ecologics also may resemble, and be applied as preliminary proxies for, analogous coefficients for Economic species. The efficacy of management strategies such as harvest refugia may differ for Ecological and Economic species, however, depending on whether the refugia are used to counter growth or recruitment overfishing.

In the presence of an onshore Ekman drift, for example, settling rates tended to increase unless the mortality rate over the reef was much higher than elsewhere. Overall, the Simulations suggest that the meanders, eddies and gyres associated with the Florida current front can retain between 0.07 and 41% of the larvae with planktonic life spans on the order of 1 month. However, only a recirculating gyre enabled large numbers of larvae to settle within a few kilometers of their birth place. Assuming the mortality rate near the reef is 20-90% per day, but lower offshore, between 0.1 and 7% of the larvae retained are likely to settle. This implies that southeast Florida reef fish populations should be able to replenish themselves without relying on upstream sources of recruitment, provided they exhibit normal fecundities. The simulations also suggest that natural levels of variation in the mortality field or local currents can both cause large fluctuations in recruitment.

AN - 16338554; 6928 AB - PURPOSE: The shock testing of SEAWOLF-class submarine at alternative areas offshore of Mayport, Florida, and Norfolk, Virginia, is proposed. The SEAWOLF, a successor to the Los Angeles-class submarine, is an attack submarine that possesses reduced acoustic and electromagnetic signatures, higher top speed, greater maximum operating depth, greater ordnance capacity, and more advanced technology than any other submarine in the U.S. fleet. The first such submarine was completed in June 1995 and is expected to be delivered to the Navy in the summer of 1996. A new submarine cannot proceed beyond initial production until realistic survivability of the system has been thoroughly tested. This testing is commonly referred to as live fire test and evaluation, which involves creating a series of underwater detonations that propagate a shock wave through a ship's hull under deliberate and controlled circumstances. Shock tests simulate near misses from underwater explosions similar to those encountered in combat. Under the proposed action, the submarine would be subjected to a series of five 10,000-pound explosive charges of incrementally increasing intensity sometime between April 1 and September 30, 2000. At both the Mayport and Norfolk areas, possible test sites were first defined as any point along the 500-foot depth corridor within 100 nautical miles of a naval station and submarine repair facility. Environmental features near each area were mapped, including marine sanctuaries, artificial reefs, hard bottom areas, shipwrecks, ocean disposal sites, and critical habitat for endangered and threatened species. In addition to the two alternative test sites, a No Action Alternative is also under consideration; new activities affecting the physical environment would be conducted. The preferred alternative would shock test the SEAWOLF submarine offshore of Mayport, Florida, with mitigation to protect marine mammals and turtles. The Norfolk was not selected because it had a higher density of marine mammals. POSITIVE IMPACTS: The shock tests would enable the Navy to implement improvements to later ships of that class. NEGATIVE IMPACTS: The explosions would result in metal fragment deposits on the ocean floor, and possible death or injury to any pelagic fish or seabirds near the detonation point. The explosions would pose some risk to marine mammals and sea turtles in the area, at the very least causing them acoustic discomfort. Commercial and recreational fishing within ten nautical miles of the detonation point would be temporarily interrupted.

AN - 16342382; 6917 AB - PURPOSE: The reconstruction or modification of the new Maryland Route 331 (MD 331) bridge over the Choptank River, located on the Eastern Shore of Maryland, is proposed. The existing Dover Bridge, located six miles east of the city of Easton, would be replaced. The Dover Bridge is one of only three remaining single swing-span bridges in Maryland on the state system and the only remaining operating metal truss swiz-span bridge in Maryland eligible for inclusion in the National Register of Historic Places. The existing bridge has recently suffered mechanical malfunctions and operational problems and is deemed functionally obsolete due to its narrow road width. In addition to a No-Build Alternative, which would involve routine maintenance and spot improvements to the existing bridge, two build alternatives which would incorporate the existing bridge, and four new alignment alternatives which would involve the replacement of the bridge, are considered in this draft EIS. The Modification Alternative would involve the alteration of the curb and rail system of the existing bridge to provide additional roadway width and its upper diagonal architectural knees at the entrance portals of each of the three truss spans to increase roadway space for trucks and eliminate any perception of clearance constraints and, if structurally feasible, an installation of a detachable walkway outside the truss on one or both sides of the span to accommodate pedestrian and bicycle traffic. The Dual Bridge Alternative would provide a single-lane roadway on a fixed structure (32-foot deck width accommodating one 12-foot lane and two 10-foot shoulders) parallel to the existing bridge to accommodate westbound traffic. Each of the new alignment alternatives would feature a 50 mile-per-hour (mph) vertical design speed with maximum vertical grades of four percent, a typical section consisting of two 12-foot lanes and two eight-foot shoulders, and a 60-mph horizontal design speed. Two of the new alignment alternatives would be located north of the bridge and two south of the bridge. POSITIVE IMPACTS: The bridge design would accommodate vehicular, pedestrian, bicycle, and marine traffic while minimizing adverse impacts to environmental resources. NEGATIVE IMPACTS: The new alignment alternatives located to the south of the existing bridge would adversely affect one early colonial historic site. Shading, pier construction, and embankment placement would adversely affect as much as 4.7 acres of wetlands under the new alignment alternatives. Terrestrial resources could also be adversely affected, including agricultural fields and narrow pioneer edge forests. One tree, a 32-inch-diameter sycamore could be adversely affected. The dual bridge and new alignment alternatives would displace 1.8 to 3.0 acres of prime farmland and 0.2 to 1.9 acres of statewide important farmland.

AN - 16342449; 6902 AB - PURPOSE: The restoration of natural resources damaged by long-term industrial pollution in New Bedford Harbor, located in southeastern Massachusetts, is proposed. The project area includes the Acushnet River watershed, south through the Acushnet River Estuary and New Bedford Inner and Outer Harbors, out to the Area III fishing closure line, and adjacent shoreline areas. New Bedford Harbor is a small, urbanized estuary and important commercial port on western Buzzards Bay. From the late 1940's until 1977, manufacturers in New Bedford discharged industrial wastes containing polychlorinated biphenyls (PCBs) and toxic metals in the harbor and nearby coastal environments, resulting in widespread, severe contamination of the sediments, water column, and biota of the harbor estuary and parts of Buzzards Bay. Dredging of these contaminated sediments is presently underway and is expected to last ten years. Without the proposed restoration effort, the recovery of the harbor ecosystem would take decades or longer. The plan developed by the New Bedford Harbor Trustee Council contains 11 preferred alternatives and a No Action Alternative for restoring marshes and wetlands, recreational areas, and wildlife. Major restoration projects would include the hydrologic restoration of Padanaram Salt Marsh, the alteration of a culvert in the harbor to improve tidal exchange, recreational and habitat improvements to Fort Taber Park and Riverside/Belleville Avenue Marine Recreational Park, the restoration of eelgrass habitat at New Bedford Harbor and Clarks Cove, and the restoration of shellfish, the Acushnet River herring run, and Buzzards Bay tern. A plan for the hydrologic restoration of Nonquitt Marsh was deferred in response to public comment on the draft EIS. The plan would be financed through a $21.0 million fund established as a result of settlements between the federal government, the Commonwealth of Massachusetts, and the companies responsible for polluting the harbor. POSITIVE IMPACTS: By beginning restoration activities while cleanup was still underway, the proposed action would accelerate the return of the harbor ecosystem to its pre-pollution condition. NEGATIVE IMPACTS: There would be temporary traffic congestion and noise pollution due to construction.

To help fill this informational void, we conducted benthic invertebrate and sediment studies in a shallow navigation channel in the river before and after dredging. Benthic invertebrate and sediment samples were collected with a 0.1-m (super 2) Van Veen grab sampler at seven stations in the Wahkiakum County Ferry Channel. Washington (River Kilometer 70), and at an upstream reference area in 1993-1995. No significant effects (P>0.05) of the ferry channel dredging project on Corbicula fluminea. Ceratopogonidae larvae, Corophium spp., or total benthic invertebrate densities were detected in the statistical analysis, although benthic invertebrate densities were significantly different (P0.05) of the ferry channel dredging project on the benthic invertebrate community structure, as measured by H and E, were detected. No significant effects (P>0.05) of the ferry channel dredging project on sediment median grain size or percent volatile solids were detected. Results from this study will provide information to aquatic resource agencies that assess the potential environmental effects of dredging in similar habitats of the lower Columbia River.

A near-immediate field response and repeated plume mapping and sampling surveys during eight cruises over the next 3 years have provided a unique opportunity to estimate heat and mass fluxes from both event and chronic discharge during the life cycle of a newly created hydrothermal system. The intrusion triggered the release of at least three event plumes followed by chronic discharge focused at two sites: Flow, the site of a lava eruption at the distal end of the intrusion; and Floe, 30 km back along the trend of the dike. We have combined measurements of plume temperature anomalies, plume areal extent, and year-long averages of current flow at both sites to estimate the chronic hydrothermal heat flux H (sub u) . Initial values of H (sub u) at both sites were of order 10 (super 4) MW, declining over time t as H (sub u) = at (super -k ) , with k nearly equal 1. Significant plumes were no longer detectable at Flow by June 1995, or at Floe by June 1996. Elemental fluxes from the CoAxial system have been derived from H (sub u) and measurements of the ratios Mn/heat, Fe/heat, and particulate S/heat in chronic plumes. While Mn and Fe fluxes mirrored the power curve decline of heat, the combined regional particulate S (PS) flux experienced a second pronounced maximum some months after the eruption owing to a sharp increase in the S/heat ratio at Floc. Integrated inventories from chronic discharge were approximately 4 X 10 (super 17) J for heat, approximately 3 X 10 (super 8) mol for Mn, approximately 2 X 10 (super 8) mol for Fe, and approximately 1 X 10 (super 8) mol for PS. Realistic uncertainties for all species are roughly a factor of 2. The three event plumes accounted for <5% of the chronic plume inventories. Copyright 1998 by the American Geophysical Union.

The grabens are 10-100 m wide and 5-15 m deep and are located uprift and/or downrift of the eruptive vents that fed the flows. We interpret that these structures formed (or were reactivated) directly over the dike that fed the eruptions as it was intruding toward the surface. These graben structures are primary conduits for diffuse hydrothermal venting on the seafloor during the cooling of newly intruded dikes. The axial summit "graben" or "caldera" on the East Pacific Rise (EPR) in some locations has similar dimensions to the grabens observed on the JdFR, and we interpret that it too may be a dike-induced graben structure (although often buried by subsequent eruptions where it is narrowest). These grabens on the JdFR and the EPR are distinctly narrower and deeper than grabens that formed during well-documented dike intrusions on slow spreading rifts on land (Iceland and Afar). Mechanical modeling suggests that narrow grabens would form when a dike is at shallow depth where it imposes a high stress perturbation on the ambient stress state to cause faulting. Therefore the narrow grabens on the JdFR and EPR imply that a relatively high level of horizontal compressive stress typically exists perpendicular to the ridges, and this must be overcome by high dike-induced perturbations to cause faulting. This is probably because gradual plate spreading rarely gets enough time to lower the compressive stress significantly due to the high frequency of dike intrusion events relative to the plate spreading rate. The dikes that do intrude in this environment must have relatively high internal magma pressure. Therefore the size and character of dike-induced grabens that form at the surface on intermediate to fast spreading ridges reflect the fact that volcanism dominates over tectonism in regulating the local stress state where a robust magma supply is available.

The hydrographic section is composed of surveys obtained from 1990 to 1994. The potential temperature field shows pronounced downward sloping of the isotherms below 1.9 degrees (centered at about 150 m above the bottom) on either side of the ridge crest. The horizontal scale is about 2 km, comparable to the local Rossby deformation radius. The maximum potential temperature anomaly is greater than 0.03 degrees C. Significant light attenuation anomalies are also present. The mean along-ridge velocity section is constructed from the records of 85 current meters. The mean flow is southward at and to the east of the vent and northward to the west. Largest velocities occur at the depth of the neutrally buoyant plume. The cross-ridge shear is thus anti-cyclonic with a characteristic value of -0.05f. Geostrophic velocity fields obtained from the density section differ significantly from the field produced from the current meter data. An estimate of the net mean flux of anomalous heat gives 780 (+ or -400) MW to the south. Copyright 1998 by the American Geophysical Union.

Adults are exclusively intestinal parasites of vertebrates. This study includes those species found in vertebrates of marine and estuarine environments along the North American Atlantic coast between Maine and Texas. Species that can be found within that geographical range and those that typically infect freshwater fishes but that are occasionally present in marine or estuarine hosts are also included. The taxonamy, anatomy, natural history, and ecology of the phylum Acanthocephala are discussed, and an illustrated key to the genera is presented. Techniques, an annotated systematic treatment of all 43 species, and a systematic index are included. No systematic decisions will be made at this time, but areas where such decisions are pending will be indicated and discussed for future reports.

A discrimination function based on gonadosomatic indices was developed to classify maturation state of Atlantic salmon caught in Newfoundland and Labrador fisheries during the period 1985-1988. Atlantic salmon believed to be on feeding migrations were found to be in advanced states of sexual development. In an attempt to clarify the meaning of these data, chronological transects of Sr:Ca ratios from the otoliths of maturing and immature one-seawinter fish were collected. Sr:Ca ratios deposited during freshwater residency varied by stock and appeared to reflect the environmental availability of Sr. Sr:Ca ratios deposited during marine residency appeared to reflect somatic growth and sexual development. We detected no differences in the postsmolt Sr:Ca ratios for mature and immature Atlantic salmon from a hatchery stock originating in North America, suggesting that for this stock, little differentiation occurs between the maturity components. Mechanisms by which environment may contribute to the variation in maturation rate of North American Atlantic salmon are discussed.

Despite the widespread use of echosounders, few guidelines aid in the choice of appropriate sonar system parameters for acoustic surveys. Choice of acoustic carrier frequency is analogous to the choice of spotlight colour used to illuminate a painting. Three primary biological factors influence the scattering of sound by aquatic organisms: swimbladder presence, organism length, and organism behaviour. We illustrate the influence of these factors on the amplitude of backscattered echoes using a Kirchhoff-ray mode scattering model to quantify fish and zooplankton backscatter as a function of carrier frequency, fish length, and swimbladder aspect. Model results illustrate that echo amplitudes from aquatic organisms are largely dependent on the presence or absence of a swimbladder. Target strengths generally increase with increasing carrier frequency and organism length. Swimbladder angle relative to the incident sound wave affects scattering amplitudes at all frequencies. Measurements of backscatter from swimbladdered fish are relatively robust when the ratio of fish length to acoustic frequency wavelength ranges between 2 and 10. As fish length to frequency wavelength ratios increase, echo amplitudes become more dependent on aspect and peak when the swimbladder is perpendicular to the acoustic wavefront.

Midway Islands (Fig. 1) is the site of the most depleted monk seal population. Because of continuing Navy operations at Midway in the early 1980s, it was not practical to include Sand Island at Midway in the designation of critical habitat for the species. For the same reason the HMSRT did not recommend specific recovery efforts at Midway in the Recovery Plan. With the recent closure of the Midway Naval Air Facility, establishment of the Midway Atoll National Wildlife Refuge (Refuge), and transfer of the atoll to the U.S. Fish and Wildlife Service (USFWS) in June 1997, planning to recover this endangered seal population must now begin. On December 5-6, 1995, the Honolulu Laboratory of the National Marine Fisheries Service (NMFS), conducted a workshop to develop recommendations to facilitate recovery of the monk seal population at Midway. Workshop participants were presented background data on the Midway monk seal population, results of the 1992 monk seal rehabilitation and translocation to Midway, population trend data for certain Midway reef fishes, and results of the Kure Atoll monk seal recovery efforts during 1985-91 and 1993-95. The USFWS management strategy for the Refuge was also presented. The recommendations of this workshop were the basis for developing recovery actions presented in this document.

One thousand and thirteen fur seals (565 males and 448 females) were measured in a longitudinal study and an additional 2697 animals were measured at birth. At birth, female pups were about 10% lighter and about 3% shorter than male pups. The coefficients of variation of mass (12.5 and 12.8%) and length (4.5 and 4.7%) were similar for the two sexes. We partitioned the lactation period into four time periods: 1, the perinatal period (ages 0-10 days); 2, the early development period (ages 11-40 days); 3, the period of intensive molting (ages 41-80 days); and 4, the preweaning period (ages 81-140 days).

ER - TY - JOUR T1 - Foraging modes of chinstrap penguins: contrasts between day and night AN - 17095175; 4392913 AB - Penguins rely on vision to travel and hunt at sea. Vision in marine predators, particularly those hunting phototactic prey under a broad range of light intensities, must be better understood to realize how these species respond to changes in their environment. We studied the effects of daily cycles in light intensity on visual predators by examining the duration and timing of chinstrap penguins' Pygoscelis antarctica foraging trips and the size, composition, and timing of their meals. We used radio telemetry and stomach-contents sampling to study adult penguins that were provisioning chicks during the summers of 1993 and 1994 at Seal Island, Antarctica. The penguins rarely initiated or terminated foraging trips at night, but otherwise varied the timing and duration of trips to sea. Cluster analyses using departure and arrival times revealed 5 distinct modes of foraging: 3 were strictly diurnal (early, mid-, and late) and 2 were partly nocturnal (overnight and extended). Durations of diurnal trips (4 to 11 h) were shorter than overnight (13 to 14 h) and extended trips (18 to 22 h). Early and mid-diurnal trips and extended trips were significantly shorter in 1993 than in 1994; late diurnal and overnight trip durations did not differ between years. Diurnal foraging was most common in 1993, whereas overnight foraging predominated in 1994. Shortened diurnal foraging in 1993 appears to have increased the frequency of diurnal foraging by allowing more parent birds to alternate diurnal trips within a single day and by reducing the incidence of birds extending diurnal foraging through the night. That penguins foraged more frequently by day when permitted by shorter trip durations (in 1993) suggests that they opted to forage diurnally whenever possible. Returning diurnal and overnight foragers had greater than 99 and 74% Antarctic krill Euphausia superba by weight in their stomachs, respectively. However, overnight foragers also returned with significant amounts of highly digested remains of pelagic fish, suggesting birds were in offshore waters taking fish during the night. In contrast, only 1 out of 40 diurnal foragers from both years combined had evidence of fish. Thus, the daily light cycle affected both the timing and duration of chinstrap penguin foraging as well as the type of prey consumed during trips to sea.

There were five intense (or major) Saffir-Simpson category 3, 4, or 5 hurricanes (average is 2.3 intense hurricanes) with 11.75 intense hurricane days (average is 4.7). The net tropical cyclone activity, based upon the combined values of named storms, hurricanes, intense hurricanes, and their days present, was 229% of the average. Additionally, 1995 saw the return of hurricane activity to the deep tropical latitudes: seven hurricanes developed south of 25 degree N (excluding all of the Gulf of Mexico) compared with just one during all of 1991-94. Interestingly, all seven storms that formed south of 20 degree N in August and September recurved to the northeast without making landfall in the United States. The sharply increased hurricane activity during 1995 is attributed to the juxtaposition of virtually all of the large-scale features over the tropical North Atlantic that favor tropical cyclogenesis and development. These include extremely low vertical wind shear, below-normal sea level pressure, abnormally warm ocean waters, higher than average amounts of total precipitable water, and a strong west phase of the stratospheric quasi-biennial oscillation. These various environmental factors were in strong contrast to those of the very unfavorable conditions that accompanied the extremely quiet 1994 hurricane season. The favorable conditions for the 1995 hurricane season began to develop as far back as late in the previous winter. Their onset well ahead of the start of the hurricane season indicates that they are a cause of the increased hurricane activity, and not an effect. The extreme duration of the atmospheric circulation anomalies over the tropical North Atlantic is partly attributed to a transition in the equatorial Pacific from warm episode conditions (El Nino) to cold episode conditions (La Nina) prior to the onset of the hurricane season. Though the season as a whole was extremely active, 1995's Atlantic tropical cyclogenesis showed a strong intraseasonal variability with above-normal storm frequency during August and October and below normal for September. This variability is likely attributed to changes in the upper-tropospheric circulation across the tropical North Atlantic, which resulted in a return to near-normal vertical shear during September. Another contributing factor to the reduction in tropical cyclogenesis during September may have been a temporary return to near-normal SSTs across the tropical and subtropical North Atlantic, caused by the enhanced tropical cyclone activity during August. Seasonal hurricane forecasts for 1995 issued at Colorado State University on 30 November 1994, 5 June 1995, and 4 August 1995 correctly anticipated an above-average season, but underforecast the extent of the extreme hurricane activity.

The sensitivity of the new parameters was tested by individual parameter perturbation (IPP) analysis. The model was applied to estimate individual and total cohort food consumption of age-0 pollock in two areas of high pollock density in the Gulf of Alaska during the summer of 1990. Total cohort consumption was compared with zooplankton biomass and production estimates for the same areas and times of the year. The model was also used to examine the bioenergetic implications of age-0 pollock diel vertical migration through a thermal gradient. During a 1-month bioenergetics simulation, individual daily consumption decreased from 16 times 0% to 6 times 0% of wet body weight. Daily ration estimates corresponded well with independent field estimates of daily ration for the same areas and time of the year. Comparison of total cohort consumption with prey availability (production and biomass) indicated minimal potential for food limitation. Bioenergetic optimization of growth can be a potential benefit of diel vertical migration to age-0 pollock, however more information on prey density and distribution is needed to test this hypothesis thoroughly.

Toxaphene was the dominant organochlorine contaminant in the Lake Superior food web, with concentrations 2-15 times higher than total PCBs. Among the biota studied, wet weight toxaphene levels were highest in bloaters (Coregonus hoyi) at 1100 plus or minus 270 ng/g (mean plus or minus 1 standard deviation) and lowest in Mysis relicta (32 plus or minus 804 ng/g). Total PCB concentrations ranged more than a factor of 20 on a wet weight basis but less than a factor of 6 on a lipid weight basis. The lipid content of the organisms explains 81% of the variability in wet weight t-PCB, with trophic position exerting a smaller influence. Using path analysis and regression techniques, the main influence of trophic position on t-PCBs was shown to be due to the concurrent increase in lipid content with trophic position. The relative distributions of organochlorines among trophic levels were very similar, despite the 3 orders of magnitude range in OC hydrophobicity. Unlike our work in Lake Baikal, the accumulation of OCs in the Lake Superior food web was not significantly (p < 0.05) related to the log octanol/water (K sub(ow)) partition coefficient, suggesting either that organochlorines in this food web equilibrate with surrounding dissolved OCs rapidly relative to dietary uptake or that the OC assimilation efficiency of predators does not vary with log K sub(ow).

The navy initially contracted Hughes Aircraft Company to develop a rainfall-retrieval algorithm prior to the launch of SSM/I. This first-generation operational navy rainfall retrieval algorithm, referred to as the D-Matrix algorithm, was used until the development of the second-generation algorithm by the SSM/I Calibration/Validation team, which has subsequently been replaced by a third-generation algorithm developed by the National Oceanic and Atmospheric Administration/National Environmental Satellite, Data and Information System. Results from both the D-Matrix and Cal/Val algorithms have been included in a total of five algorithm intercomparison projects conducted through the Global Precipitation Climatology Project and WetNet. A comprehensive summary of both quantitative and qualitative results from these intercomparisons is given detailing many of the strengths and weaknesses of the algorithms. Based on these results, the D-Matrix algorithm was found to produce excessively large estimates over land and to poorly represent the spatial structure of rainfall systems, especially at higher latitudes. The Cal/Val algorithm produces more realistic structure within storm systems but appears to overestimate the region of precipitation for many systems and significantly underestimates regions of intense rainfall. While the Cal/Val algorithm appears to provide better instantaneous rainfall estimates in the Tropics, the D-Matrix algorithm provides reasonable time-averaged results for monthly or longer periods.

This is accomplished through use of a new technique, biohydro-optical classification, that applies a rudimentary submarine light budget incorporating climatologies of incident light, mixed-layer thickness, and chlorophyll to recognize fundamental modes of tropical plankton ecosystems. The 3 types of biohydro-optical classes found in the Arabian Sea, Typical Tropical, Mixed-Layer Bloom, and Transitional, are shown to evolve through the spring intermonsoon (March through May), summer southwest monsoon (June through August), and fall intermonsoon (September through November) under climatic forcing and in response to the resulting biological variability. Virtually all of the open Arabian Sea is within the Typical Tropical Class at the close of the spring intermonsoon. This class type is intended to identify the epipelagic plankton ecosystem mode associated with tropical regions containing a deep chlorophyll maximum (DCM) maintained by active algal growth, and a light-rich, oligotrophic shallow zone containing a phytoplankton association which depends largely upon regenerated nutrients. At the close of the southwest monsoon in August, a Mixed-Layer Bloom Province covers much of the northern Arabian Sea. This province class corresponds to the ecosystem mode represented by tropical regions undergoing marginal or mid-ocean upwelling and greatly simplifies regional extrapolation of the local primary production algorithm. At the onset of the fall intermonsoon, the Mixed-Layer Bloom Province in the northern and western Arabian Sea is superseded by a Transitional Province, which persists through the fall intermonsoon. We interpret the upper layer of the fall intermonsoon Transitional Province in the Arabian Sea as a special case of the shallow regenerative plankton ecosystem of oligotrophic ocean areas, where rates of zooplankton-driven nutrient regeneration and recycled production, key processes in the upper layer of the classic 2-layer euphotic zone of oligotrophic low-latitude oceans, reach extreme values.

This objective was addressed in two separate phases. In the first study, concentrations of AHs and PCBs were measured in individual fish from four sites in Puget Sound, Washington (Eagle Harbor, Sinclair Inlet, Yukon Harbor, and Pilot Point) with different levels of AH and PCB contamination in sediments and their ovarian development was monitored during the 1989-1991 spawning seasons. In these fish, egg weight was negatively correlated with levels of PCBs in the liver. However, contaminant exposure levels were not significantly associated with the probability of entering vitellogenesis or with gonadosomatic index, plasma estradiol concentrations, or fecundity. In the second study, gravid female soles were taken from Eagle Harbor, Sinclair Inlet, Yukon Harbor, and University Point (known spawning areas for rock soles), and hormonally induced to spawn in the laboratory. Eggs were fertilized with pooled sperm from reference males. Consistent with the first study's findings, fish from Sinclair Inlet, where sediments contain elevated concentrations of PCBs, produced eggs with significantly reduced weight. Furthermore, the overall spawning success of fish from the site with the highest level of AH contamination (Eagle Harbor) was significantly impaired. These findings suggest that environmental exposure to AHs and PCBs may reduce reproductive success in female rock soles, but this species appears to be more resistant to such effects than other Puget Sound flatfish species, such as the English sole Pleuronectes vetulus.

Immunosuppressed fish may be more susceptible to disease and ultimately experience an increase in mortality. To evaluate this possibility, differences in susceptibility to a marine pathogen in outmigrating juvenile chinook salmon from an urban estuary and a nonurban estuary in Puget Sound were assessed. Juvenile chinook salmon were sampled from hatcheries before their release and subsequently from their respective estuaries as the population outmigrated from freshwater to the saltwater environment during the springs of 1993 and 1994. The study was repeated during a 3-month period to assess the duration of the effect after the fish were removed from the source of contaminants and was replicated during a 2-year period to examine interannual variation. Bile, liver, and stomach contents were collected from fish after capture to determine exposure to organic chemical pollutants. Examination of these tissues demonstrated that juvenile salmon from the urban estuary were exposed to higher concentrations of polycyclic aromatic hydrocarbons and polychlorinated biphenyls than juveniles from the nonurban estuary or hatcheries. Juvenile salmon were challenged with serial doses of a marine pathogen, Vibrio anguillarum (serotype 1575), and mortality was measured daily for 7 d. In both years. salmon from the urban estuary challenged with V. anguillarum exhibited a higher cumulative mortality after exposure to the pathogen than salmon from the hatcheries or the nonurban estuary. Our results together with our previous findings support the hypothesis that contaminant-associated immunodysfunction in juvenile chinook salmon may lead to increased susceptibility to infection by a virulent marine bacterium.

The assessment of the model was based on changes to the deep convection and planetary boundary layer parameterizations to determine their impact on some of the model deficiencies identified during previous hurricane seasons. Some of the deficiencies in the hurricane forecasts included a weakening of the storm circulation with time that seriously degraded the track forecasts. In the larger-scale forecasts, an upper-level easterly wind bias was identified in association with the failure of the model to maintain the midoceanic upper-tropical upper-tropospheric trough. An overall modest improvement is shown in the large-scale upper-level tropical winds from root-mean-square-error calculations. Within a diagnostic framework, an improved simulation of the midoceanic tropical trough has contributed to a better forecast of the upper-level westerly flow. In the hurricane forecasts, enhanced diabatic heating in the model vortex has significantly improved the vertical structure of the forecast storm. This is shown to contribute to a substantial improvement in the track forecasts.

At landfall, Luis and Marilyn contained maximum sustained winds (marine exposure) estimated at near 60 and 46 m s super(-1), respectively. The strongest landfalling storm of the 1995 season, Luis, decreased in intensity from a category 4 to 3 on the Saffir-Simpson scale shortly before the eyewall crossed the Islands of Antigua, Barbuda, St. Kitts-Nevis, St. Barthelemy, St. Martin, and Anguilla. Hurricane Marilyn strengthened as it approached the U.S. Virgin Islands, with St. Thomas bearing the brunt of the north and south eyewall winds of 46 m s super(-1) (marine exposure) and St. Croix being affected by the relatively weak western eyewall peak winds of 35-40 m s super(-1) (marine exposure). For Luis and Marilyn only surface winds with marine exposures were analyzed because of unknown small-scale interactions associated with complex island terrain with 500-1000-m elevations. Wind engineering studies suggest that wind acceleration over blunt ridges can increase or "speed up" winds by 20%-80%. Topographic effects were evident in damage debris analyses and suggest that an operational method of assessing terrain-induced wind gusts (such as a scaled down mesoscale model) is needed. After landfall as a marginal hurricane over central Florida, Hurricane Erin regained strength over the Gulf of Mexico with a well-defined radar reflectivity structure. Erin struck the Florida panhandle near Navarre Beach with maximum sustained surface winds of 35-40 m s super(-1) affecting the Destin-Ft. Walton area. Hurricane Opal made landfall in nearly the identical area as Erin, with maximum sustained surface winds of 40-45 m s super(-1), having weakened from an intensity of nearly 60 m s super(-1) only 10 h earlier. Opal was characterized by an asymmetric structure that was likely related to cold front interaction and an associated midlevel southwesterly jet. Roxanne struck Cozumel, Mexico, with sustained surface winds (marine exposure) of 46 s super(-1), crossed the Yucatan, and meandered in the southwest Gulf of Mexico for several days. While in the Bay of Campeche, Roxanne's large area of hurricane-force winds disabled a vessel, which lead to the drowning deaths of five oil industry workers. High-resolution wind records are critical to preserving an accurate extreme wind climatology required for assessment of realistic building code risks. Unfortunately, power interruptions to Automated Surface Observing Stations on the U.S. Virgin Islands (St. Croix, St. Thomas) and Destin, Florida, prevented complete wind records of the eyewall passages of Marilyn and Opal, respectively.

The Fv is composed of the polypeptide chains of the V sub(H) and V sub(L) domains expressed independently and isolated as inclusion bodies. The Fv is prepared by combining and refolding equimolar amounts of guanidine chloride solubilized inclusion bodies. The Fv is stabilized by an engineered interchain disulfide bridge between residues V sub(L)100 and V sub(H)44. This construct has a similar binding affinity as that of the single-chain construct (Benhar and Pastan, Clin. Cancer Res. 1:1023-1029, 1995). The B1 disulfide-stabilized Fv (B1dsFv) crystallizes in space group P6 sub(1)22 with the unit cell parameters a = b = 80.1 angstrom, and c = 138.1 angstrom. The crystal structure of the B1dsFv has been determined at 2.1-angstrom resolution using the molecular replacement technique. The final structure has a crystallographic R-value of 0.187 with a root mean square deviation in bond distance of 0.014 angstrom and in bond angle of 2.74 degree . Comparisons of the B1dsFv structure with known structures of Fv regions of other immunoglobulin fragments shows closely related secondary and tertiary structures. The antigen combining site of B1dsFv is a deep depression 10-angstrom wide and 17-angstrom long with the walls of the depression composed of residues, many of which are tyrosines, from complementarity determining regions L1, L3, H1, H2, and H3. Model building studies indicate that the Lewis super(Y) tetrasaccharide, Fuc-Gal-Nag-Fuc, can be accommodated in the antigen combining site in a manner consistent with the epitope predicted in earlier biochemical studies (Pastan, Lovelace, Gallo, Rutherford, Magnani, and Willingham, Cancer Res. 51:3781-3787, 1991). Thus, the engineered disulfide bridge appears to cause little, if any, distortion in the Fv structure, making it an effective substitute for the B1 Fab.

Under the auspices of the National Oceanic and Atmospheric Administration's National Status and Trends Program, the National Benthic Surveillance Project accumulated a database of synoptic sediment contaminant concentrations and indices of biological effects that were measured in indigenous animals collected during field surveys conducted from 1984 to 1994. This compilation of data provided the opportunity to develop a new approach for determining sediment quality criteria to add to the current repertoire of environmental assessment tools. Using a two-segment hockey stick regression, statistically significant chemical thresholds of biological effects were estimated for hepatic lesion prevalences in English sole (Pleuronectes vetulus, formerly Parophrys vetulus) in relation to sediment concentrations of polycyclic aromatic hydrocarbons. These threshold estimates are notably lower than many of those reported for other techniques. Application of this relatively simple dose-response model to subacute, chronic effects that are involved in hepatocarcinogenesis and associated with sediment toxicant content (1) reflects the link between toxicopathic disease progression and conditions observed in benthic fish exposed to contaminants and (2) provides endpoints for assessing sediment quality contaminant concentrations that are not necessarily acutely fatal but may have long-term health implications for populations that are chronically exposed.

Migratory and endemic species of whales, seals and birds benefit from the high biomass of their principal prey, krill (Euphausia superba) and cephalopods, in this area. Most species of baleen whales and male sperm (Physeter macrocephalus) whales in the Southern Hemisphere migrate between low-latitude breeding grounds in winter and highly productive Antarctic feeding grounds in summer. Here I show the importance of the southernmost reaches of the strongest ocean current, the Antarctic Circumpolar Current (ACC), to a complex and predictable food web of the Southern Ocean. The circumpolar distributions of blue (Balaenoptera musculus), fin (Balaenoptera physalus) and humpback (Megaptera novaeangliae) whales from spring to midsummer trace the non-uniform high-latitude penetration of shoaled, nutrient-rich Upper Circumpolar Deep Water, which is carried eastward by the ACC. The poleward extent of this water mass delineates the Southern Boundary of the ACC and corresponds not only to the circumpolar distributions of baleen whales, but also to distributions of krill and to regions of high, seasonally averaged, phytoplankton biomass. Sperm whales, which feed on cephalopods, also congregate in highest densities near the Southern Boundary. The association of primary production, Krill, and whales with the Southern Boundary, suggests that it provides predictably productive foraging for many species, and is of critical importance to the function of the Southern Ocean ecosystem.

AN - 16339232; 6844 AB - PURPOSE: The construction of a 74,500 square-foot marine environmental health research laboratory at Charleston, South Carolina, is proposed. The facility would support collaborative scientific research by scientists from the National Ocean Service of the National Oceanic and Atmospheric Administration (NOAA), the National Institute of Science and Technology, South Carolina's Department of Natural Resources, and two nearby academic institutions. The facility would be constructed on eight acres on Fort Johnson on the northeast point of James Island, across Charleston Harbor from the city of Charleston. The preferred site is located on the south side of Johnson Road, just to the east of the existing laboratory, which constructed in 1978. The existing facility cannot support the high-technology science applications necessary for current research. Phase one of the project would involve the construction of a laboratory designed to accommodate 90 scientists. Phase two would involve the construction of a 8,250 square-foot dormitory, dining facility, and visiting scientist housing. The housing units would consist of five 1,250-square foot townhouses. The units would be self-contained and independent of other facilities. POSITIVE IMPACTS: The construction of the facility would enable scientists to conduct state-of-the-art stock assessments of critical fish populations, characterize the physical and chemical environment, monitor changes in ecosystems and community structures, monitor the health impacts on organisms of natural and anthropogenic changes, and evaluate the effectiveness of fishery management tools. NEGATIVE IMPACTS: The project would adversely affect wetland and cultural resources. The construction activity would result in increased flow and suspended sediments that would adversely affect surface water quality.

Salinity in the plumes was depressed 1-2 parts per thousand compared to surrounding shelf waters. One plume was at least 160 km long, 20 km wide, and 5-7 m deep. The other was 75 km long, 25 km wide and 5-7 m deep. Both plumes disintegrated almost completely in 6 days due to mixing or advection away from the sampling area. Measurement and analysis of short-lived Ra isotopes and Si indicated that the plumes were not caused by river discharge but were rather due to an intense rain event a few days prior to the sampling cruise. With only salinity measurements we would have incorrectly concluded that the freshened water was a result of river plumes having entered the shelf. The rain was associated with the system that spawned tropical storm Alberto. We estimate that 220-330 mm of rain fell on the coastal ocean immediately before the cruise. Accompanying the rain were pesticides and nutrients. We estimate that the flux of nitrate from the rain was twice the riverine flux of nitrate to the study area in the month preceding the cruise.

N1 - Last updated - 2014-05-06 ER - TY - JOUR T1 - Oxygen isotopic equilibrium between carbon dioxide and water in soils AN - 17170277; 4472280 AB - Exact mathematical solutions are presented for some simple cases of isotopic equilibration of oxygen-18 between carbon dioxide and water in soils, which is a major component of the super(18)O isotopic balance of atmospheric CO sub(2). The soil-to-air exchange is made up of 2 components. First, respiratory CO sub(2) is produced in the soil and escapes to the atmosphere through diffusion. The lighter isotopic species escapes a little more rapidly, enriching the heavier isotopic species in the CO sub(2) left behind in the soil, which is then out of isotopic equilibrium with soil water. Therefore, simultaneously with the escape of gas, there is continuous re-equilibration of CO sub(2) with soil water. The second component of soil-to-air exchange is independent of the production of CO sub(2) in the soil: the invasion of atmospheric CO sub(2) into the soil, where it equilibrates isotopically with the soil moisture before diffusing back out. A consequence for atmospheric isotopic measurements is that, in general, for respired CO sub(2) a plot of the isotopic ratio versus the inverse of the concentration is curved, and that the slope in the vicinity of the ambient concentration may not point towards the isotopic ratio of the net CO sub(2) evolved from the soil.

Fish avoided fresh tailings in favour of natural marine sediment (control) and weathered tailings (75 years old). Only when fresh tailings were covered with 2 cm of control sediment did fish prefer control and fresh tailings equally. Survival of fish was similar (p = 0.66) for fish held on all test sediments. Fish held on fresh tailings for 60 d grew significantly (p = 0.013) less than control fish during the first, but not the second, month. Avoidance or short-term reductions in flatfish growth may occur from submarine disposal of tailings. Rapid burial of tailings in areas with high natural sedimentation (e.g., large river mouths) may accelerate recovery of the sea floor.

The Great Lakes Environmental Research Laboratory used their conceptual models for simulating moisture storages in, and runoff from, the 121 watersheds draining into the Great Lakes, over-lake precipitation into each lake, and the heat storages in, and evaporation from, each lake. This transposition of actual climates incorporates natural changes in variability and timing within the existing climate; this is not true for General Circulation Model-generated corrections applied to existing historical data in many other impact studies. The transposed climates lead to higher and more variable over-land evapotranspiration and lower soil moisture and runoff with earlier runoff peaks since the snow pack is reduced up to 100%. Water temperatures increase and peak earlier. Heat resident in the deep lakes increases throughout the year. Buoyancy-driven water column turnover frequency drops and lake evaporation increases and spreads more throughout the annual cycle. The response of runoff to temperature and precipitation changes is coherent among the lakes and varies quasi-linearly over a wide range of temperature changes, some well beyond the range of current GCM predictions for doubled CO sub(2) conditions.

Habitat affinities were quantitatively defined using consistently collected data with a 16-m high-rise otter trawl at 314 Virginian Province (US) sites from 1990 to 1993. Catch rates and field-recorded salinity, depth, sea bed type, and geography (coastal system) associated with each trawl were analysed. Habitat affinity was quantified by comparing the concentration of fish in a particular habitat with the prevalence of that habitat. Fishes exhibited a specific habitat affinity even though they occurred across a range of environmental gradients. Fish were most associated with salinity (14 of 19 species/life-stage groups had a significant affinity for at least one salinity zone). Three-quarters of the flatfish displayed an affinity for a selected sea bed type; the same percentage of sciaenids had an affinity for a particular salinity zone.

These additives reduce the flammability of a wide variety of common polymers such as polypropylene, nylon, polymethylmethacrylate, poly(vinyl alcohol), and cellulose. In an effort to determine how these additives reduce polymer flammability, we have used electron paramagnetic resonance spectroscopy and solid-state super(13)C and super(29)Si nuclear magnetic resonance spectroscopy to characterize the combustion chars or residues. These data indicate that, in the case of poly(vinyl alcohol), the additives do not change the type of char formed, but they do change the rate of char formation relative to the rate of fuel generation. We also found that, using only CP/MAS super(13)C NMR, there can be significant intensity distortions which complicate interpretation, if the char is hydrogen depleted and contains paramagnetic centres.

Although previous genetic surveys have revealed considerable genetic differences among populations with different life history types and from different major river drainages, it is not clear to what degree these genetically distinct populations are connected by low levels of gene flow. The work described in this paper addresses this question by surveying DNA restriction site variation at six nuclear genes from nine populations encompassing most of the species's North American range, and then attempting to fit the patterns of variation observed at these genes to five different evolutionary models using computer simulations of the coalescent process. Two commonly used constant population size models, one hypothesizing no migration among populations and one hypothesizing equal rates of migration among populations, were found to be statistically inconsistent with the observed patterns of variation. The other three models, which involved either recent divergence among populations coupled with large changes in populations size, unequal migration rates among populations, or selection, were all found to be consistent with the observed patterns of variation. Assuming selective neutrality, these results suggest that either the populations have all descended from a common ancestral population within the last similar to 50,000 years and have all suffered large declines in effective population size since that time, or that they have a more ancient divergence time but are connected by low levels of gene flow. These conclusions rest on the assumption of selective neutrality. With the methods employed, it was not possible to simultaneously test hypotheses of both selective neutrality and population structure.

I find also that there is no correspondence between geographic and genetic distances separating subpopulations, an increasingly common result in spatially stratified studies of genetic structure in marine invertebrates. F-statistics, calculated for two years from electrophoretic variation at five polymorphic allozyme loci, indicate significant genetic differentiation among sampling quadrats within each of two bays ( theta = 0.064-0.208), between tide zones within a bay ( theta = 0.025-0.157) and between bays ( theta = 0.079). Spatial autocorrelation analysis was used to explore genetic differentiation at smaller spatial scales; estimated patch sizes (within which genetic individuals are randomly associated) indicated no appeciable genetic structure at scales less than 20 m X 20 m. Calculated values of F-statistics were a function of the spatial scale from which samples were drawn: increasing the size of the "subpopulation" included in calculation of fixation indices for the same "total" sample resulted in an increase in the magnitude of f (e.g., from 0.092 to 0.181) and a decrease in theta (e.g., from 0.186 to 0.025). On the basis of the best estimate of the spatial scale of subpopulations, the effective number of migrants per generation (N sub(e)m) ranges from 1.1 to 2.8. Genetic consequences of the disturbance regime in the eelgrass habitat sampled were extreme variation between years in the allele richness and proportion of heterozygotes in a sample and a positive relationship between the extinction probability of patches and the genetic variance among them. The changes in F-statistics as a function of sampling scale and the observation that theta among sampled quadrats was positively associated with the probability of extinction among quadrats indicated that indirect estimates of gene flow (N sub(e)m) calculated from theta should be cautiously interpreted in populations that may not yet be in drift-migration equilibrium.

Its polymorphic nature and maternal inheritance are characteristics that have, combined with its sequence information, enabled investigators to identify missing persons, war casualties and individuals involved in mass disasters and criminal cases. Various screening procedures have been developed to reduce the need to sequence samples that do not match, but DNA-sequence information is still necessary to verify a match. Even though several challenges remain before mitochondrial-DNA-sequence information can be used unambiguously, comparative mitochondrial-DNA-sequence analysis appears to be a reliable and powerful means for human identification.

Associated prey assemblages were sampled with neuston and plankton nets in 1984. Salmon diets included at least 30 taxa of prey. Crustaceans (principally hyperiid amphipods), fish, and tunicates were the most important prey of pink (O. gorbuscha), chum (O. keta), and sockeye (O. nerka) salmon. Fish were the most important prey of coho (O. kisutch) and chinook (O. tshawytscha) salmon and made up the highest percentage of stomach content weight for all salmon species. Diet shifted from crustaceans in 1983 to fish in 1984 for juvenile pink, sockeye, and chum salmon. Diet overlapped significantly (C sub( lambda )>0.60) between pink and sockeye salmon, pink and chum salmon, and chum and sockeye salmon. Coho salmon diet overlap was <0.60 in all paired comparisons. Nearly all (98.6%) of the 2,210 stomachs examined were at least half full. Although, in general, prey consumed were not very similar to prey observed in the environment, the composition of salmon diets was more similar to neuston collections than to zooplankton collections.

These data were processed to give profiles of volume scattering strength. A deep scattering layer dominated the time-depth patterns of backscatter. This layer migrated from a depth of 300-400 m during the day to 0-100 m at night, when it was located just above the thermocline. The source of backscatter was primarily small fish and squid, which are dolphin prey. Dolphin sighting rates were correlated positively with nighttime volume scattering strength above the thermocline. Spatial and temporal variability of prey biomass in the surface layer, as indexed by volume scattering strength, may have important consequences for dolphin feeding, as well as for distributional responses to habitat variability by dolphins.

Data were acquired from surveys of sediment quality performed in estuaries along the Atlantic, Pacific, and Gulf of Mexico coasts. Samples were classified as either nontoxic (p > 0.05 relative to controls), marginally toxic (p < 0.05 only), or highly toxic (p < 0.05 and response greater than minimum significant difference relative to controls). This analysis indicated that, when not exceeded, the ERLs and TELs were highly predictive of nontoxicity. The percentages of samples that were highly toxic generally increased with increasing numbers of guidelines (particularly the ERMs and PELs) that were exceeded. Also, the incidence of toxicity increased with increases in concentrations of mixtures of chemicals normalized to (divided by) the SQGs.

Although field collections have suggested that juveniles are obligate residents of the neuston, laboratory experiments on diel movements indicated the potential for downward movement during the day, when activity levels were high and active foraging would be likely. The relationship of downward movement to fish size (small vs. large juveniles), prior feeding success (high vs. low rations) and thermal structure of the water column (isothermal vs. varying intensities of thermal stratification) were tested. Thermal stratification inhibited downward movement, with sablefish displaying clear avoidance of cold water even when the thermal gradient was moderate (12 degree C top layer and 8 degree C bottom layer). However, sablefish could be induced to swim downward into cold water if food was introduced beneath the thermocline. Across all temperature treatments, occurrence in cold water significantly increased when food was present. Increasing the sharpness of the thermal gradient (top layer = 12 degree C, bottom layer = 8, 6, 4 or 2 degree C) did not affect the percentage of time spent in cold water, but did shorten the maximum time an individual would spend beneath the thermocline. Movement into cold water constituted a potentially lethal risk for juvenile sablefish; dives beneath the thermocline that exceeded 60 s resulted in loss of equilibrium and immediate death for small fish moving from 12 to 2 degree C water. Thus, sablefish displayed behavioral trade-offs between food acquisition and the physiological risk of cold temperatures, similar to previous studies documenting balancing of foraging behavior and predation risk. Behavioral responses to thermal stratification were modified by fish size and hunger level, with larger juveniles and those held on low rations spending more time in cold water. These behavioral responses correspond with the high feeding requirements necessary to maintain the naturally rapid growth rates of this species and the transitions in habitat associated with different life history stages.

The subtilisin BPN' variant, Sbt70, was cloned and expressed in Escherichia coli without the prodomain, the 77-residue N-terminal domain that catalyzes the folding of the enzyme into its native tertiary structure. Sbt70 has the high-affinity calcium-binding loop, residues 75 to 83, deleted. Such calcium-independent forms of subtilisin BPN' refold independently while retaining high levels of activity. Sbt70 has, in addition, seven stabilizing mutations, K43N, M50F, A73L, Q206V, Y217K, N218S, Q271E, and the active site serine has been replaced with alanine to prevent autolysis. The purified Sbt70 folded spontaneously without the prodomain and crystallized at room temperature. Crystals of Sbt70 belong to space group P2 sub(1)2 sub(1)2 sub(1) with unit cell parameters a = 53.5 angstrom, b = 60.3 angstrom, and c = 83.4 angstrom. Comparison of the refined structure with other high-resolution structures of subtilisin BPN' establishes that the conformation of Sbt70 is essentially the same as that previously determined for other calcium-independent forms and that of other wild-type subtilisin BPN' structures, all folded in the presence of the prodomain. These findings confirm the results of previous solution studies that showed subtilisin BPN' can be refolded into a native conformation without the presence of the prodomain. The structure analysis also provides the first descriptions of four stabilizing mutations, K43N, A73L, Q206V, and Q271E, and provides details of the interaction between the enzyme and the Ala-Leu-Ala-Leu tetrapeptide found in the active-site cleft.

All samples were tested for toxicity with a battery of complimentary laboratory bioassays. The laboratory bioassays consisted of amphipod survival tests in solid-phase sediments, microbial bioluminescence (Microtox(TM)) tests of organic solvent extracts, and sea urchin fertilization and embryo development tests of porewaters. Some samples also were tested in copepod reproduction and cytochrome P-450 RGS bioassays. Chemical analyses for a suite of trace metals, organic compounds, and sedimentological factors were performed with portions of most samples.

Observers using SCUBA estimated grouper populations at 13 patch reef sites. There appeared to be no significant effect from spear fishing on the relative abundance of the grouper species studied. Patch reefs protected from spear fishing had significantly greater sizes of individuals compared with unprotected patch reefs, probably because spear fishermen tend to target larger species and larger individuals. Spear fishing appears to have a greater influence on average size of groupers than on abundance. The slow growth and reproductive characteristics of groupers make them especially vulnerable to overfishing. The ban on spear fishing in some parts of the Florida Keys has significantly benefited the size distribution of groupers. A ban on spear fishing alone, however, has not enabled grouper population levels to recover. Establishment of a marine fishery reserve should be considered as a management measure to restore and conserve grouper assemblages.

In the drift gillnet fishery for swordfish and two shark species, seven of 387 mammals that became entangled were released alive. In the set gillnet fishery for halibut and angel shark, five of 1,263 entangled mammals were released alive. The estimated mortality for the drift gillnet fishery was more than 450 marine mammals each year, with common dolphins and northern elephant seals being the most commonly entangled. California sea lions and harbor seals were the most commonly entangled mammals in the setnet fishery. Twenty turtles and three seabirds were entangled in driftnets, and six turtles and 1,018 seabirds were entangled in setnets during the entire period. Estimated fluctuations in cetacean and pinniped mortality in these fisheries over the study period are reported. Area closure is the most likely reason for declines in the number of pinnipeds and cetaceans in the setnet fishery.

While dolphin population dynamics are not likely to be affected by such a change because of current low dolphin mortality, a change in the fishing pattern could lower commercial tuna stocks because school and log sets capture moderate to large amounts of undersize or other undesirable tuna that must be discarded. Differences between tuna discards in set types were examined during 1989-92. The increase in tons of tuna discarded per set that would likely result from replacing the dolphin sets with school or log sets was predicted to be 100 times higher (in terms of weight) for log sets and 10 times higher for school sets than for dolphin sets. Hypothetically, a total replacement could lead to a 337% increase in the average tuna discard over the whole fleet. Estimated discard increases for the yellowfin tuna are given. Continued removals of this degree could threaten long-term sustainability of tuna stocks.

Analysis of the maximum ice cover reveals (i) a low (1964-1976); (ii) a high (1977-1982); and (iii) once again a low (1983-1990) ice cover regime. The high ice cover regime corresponded in part with a hiatus in El Nino-Southern Oscillation (ENSO) events and the beginning of an interdecadal change in Northern Hemisphere atmospheric circulation that started in the late 1970s. About 46% of the lowest quartile ice covers occurred during the mature phase (year + one winter) of El Nino. Only 1 year out of seven with the mature phase of El Nino between 1963 and 1990 was not associated with the lowest quartile ice cover, this was 1977, a pivotal year after which a new climatic regime in the Northern Hemisphere was established. Anomaly maps of 700 hPa geopotential height for the lowest quartile ice cover reveal a zonal flow pattern. Highest quartile ice cover was associated with meridional circulation from the Arctic directed toward the Great Lakes. Significant differences occur for highest minus lowest quartile ice cover composite 700 hPa height anomaly maps in the Pacific Ocean, the west coast of North America, north Mexico, eastern North America, north central Siberia, western Europe and the adjacent North Atlantic. Correlations between first differences (year t + 1 minus year t) of annual maximum ice cover and 700 hPa geopotential heights for winters 1963-1990 agrees with these teleconnections and were higher than the absolute time series correlations, indicating strong interannual teleconnections. Annual maximum ice cover was also significantly correlated with the tropical Northern Hemisphere teleconnection index.

AN - 36401563; 6820 AB - PURPOSE: The implementation of a revised fishery management plan (FMP) for American lobsters in the exclusive economic zone (EEZ) along the North Atlantic coast in the Gulf of Maine, from southern Cape Cod to Long Island Sound, and along the Outer Continental Shelf from Georges Bank to North Carolina, is proposed. A June 1996 stock assessment conducted by state and federal scientists concluded that lobsters were overfished in all three stock assessment areas; the problem is aggravated by increased fishing effort, which will deplete stocks even further if unchecked. Six management alternatives for the trap/pot lobster fishery, including an alternative to maintain the status quo, are considered in this draft EIS. Alternative 2 would impose to continue current management measures in the EEZ and implement additional EEZ-wide regulations on maximum trap size and minimum vent size in lobster traps. Alternative 3 would establish a cap on the number of lobster traps permitted over a four-year period and would require lobster vessels to declare in which of three zones they intended to fish. Alternative 4 would impose a four-tier nearshore and offshore trap limit and require all federal lobster permit holders using traps to certify the number of traps they actually fished in 1997. Alternative 5 would establish trap limits in three fishing zones, and would require permit holders to designate in which zone they plan to operate. Alternative 6 would require the removal of all trap gear and closure of the EEZ to lobster fishing. Three additional alternatives are under consideration for lobster vessels using gear or methods other than traps. Additional alternative 1 would limit landings to 100 lobsters for each fishing trip of 24 hours or less. Additional alternative 2 would limit landings to no more than 500 lobsters per trip regardless of trip length. Additional alternative 3 would prohibit the fishing or possession of lobster by all methods of fishing. POSITIVE IMPACTS: The alternatives would protect the lobster industry from the effects of overfishing. The spawning stock size and yield per recruit would increase significantly. NEGATIVE IMPACTS: Restrictions on the use of lobster traps could create a temporary economic hardship for existing lobster operations.

AN - 36389801; 6803 AB - PURPOSE: The implementation of an ecosystem restoration and water management program for the San Francisco Bay and Sacramento-San Delta, located in northern California, is proposed. The program area extends from southern to northern California and includes the lowlands and uplands in the Sacramento and San Joaquin River watersheds; Suisun Bay and Marsh, San Pablo Bay, and the San Francisco Bay watershed; and Tulare Lake, Consumnes River, Mokelumne River, and other rivers and waterways connected to the San Joaquin River. The bay-delta region itself refers to the 738,000-acre area south of the city of Sacramento where the Sacramento and San Joaquin rivers meet, an environmentally diverse area that supports 750 plant and animal species within the largest wetlands area in the western United States. The region also provides water to two-thirds of the state's residents and much of its agricultural industry. In recent years, the bay-delta region has experienced a steady decline as a fish and wildlife habitat and as a reliable source of water because of population increases and economic development pressures. The CALFED program was established in June 1995 by 15 state and federal agencies in order to address the complex issues affecting the bay-delta region. Four alternatives, including a No Action Alternative, are considered in this draft programmatic EIS. Each of the action alternatives would include a core program that would address the issues of ecosystem restoration, water use efficiency, water quality, Delta levee and channel integrity, water transfers, watershed management coordination, and a range of storage and conveyance options. Storage options would include 3.0 million acre-feet (MAF) surface storage on Sacramento River tributaries upstream of the delta, 500 thousand acre-feet (TAF) of storage on San Joaquin River tributaries, two MAF of storage off-aqueduct south of the delta, 200 acre-feet in-delta storage, and 250 and 500 TAF of groundwater storage in the Sacramento and San Joaquin valleys, respectively. Conveyance options would include relying on the existing system while making some minor changes in the south delta, enlarging channels within the delta, and a conveyance channel for moving water around the delta. POSITIVE IMPACTS: The program would help to restore a vital wetlands area, lower toxicants in the water system, conserve over three million acre-feet of water by the year 2020, strengthen levees throughout the Delta, reduce drought-induced economic damage by improving flows from one region to another, and improve overall watershed management. NEGATIVE IMPACTS: The construction of storage and conveyance facilities would have an adverse short-term effect on water quality and an adverse long-term effect on fish habitat and migration. Increased water conservation for ecosystem restoration would reduce water availability for agricultural and municipal uses during drought conditions. Air quality would be adversely affected for a short period. Vegetation and wildlife communities would also be adversely affected. Farmland and other agricultural land would be converted, and job losses could occur. The project could include significant visual impacts.

Thus the Eighteenth edition was hosted by the Mazatlan Research Unit of the Instituto de Ciencias del Mar y Limnologia of the Mexican National Autonomous University (UNAM) in Mazatlan, Sinaloa (Mexico) where it was held from 3-7, March, 1998. Above all, our symposium is prominent for its dynamism and enthusiasm in bringing together specialists from the world's sea turtle populations. In an effort to extend this philosophy, and fully aware of how fast the interest in sea turtles has grown, the organizers paid special attention to bring together as many people as possible. With the tremendous efforts of the Travel Committee and coupled with a special interest by the Latin American region's devotees, we managed to get 653 participants from 43 countries. The number of presentations increased significantly too, reaching a total of 265 papers, ranging from cutting-edge scientific reports based on highly sophisticated methods, to the experiences and successes of community-based and environmental education programs.

Observations on courtship and mating in leatherbacks are almost non-existent, although sea turtles are generally presumed to be promiscuous based on extensive studies of green turtles (Alvarado and Figueroa, 1991). FitzSimmons (1996) surprisingly found that multiple paternity was rare in Australian greens. Leatherback paternity studies to date have been invalid due to an insufficient number of reliable polymorphic loci. We have identified informative new microsatellite loci, and have sampled successive clutches laid by the same females over a three month period in St. Croix, U.S. Virgin Islands. A total of 6 loci were used to construct the genotypes of nesting females and their offspring. Loci were amplified by PCR using fluorescent dye-labelled primers analyzed on a 377A ABI automated sequencer with GENESCAN. Paternal genotypes were inferred by comparing the known offspring and known maternal genotypes.

AN - 21103955; 11287748 AB - The natural sex ratios of sea turtles have been of interest since the discovery of temperature-dependent sex determination (TSD) in sea turtles (Owens and Hendrickson, 1978). It is possible that the sex ratio within a management unit is dynamic, varying among cohorts. Studies have shown that adult populations are difficult to evaluate for sex ratios due to various sex-determined behaviors (Wibbels et al., 1987). Likewise, the sex ratios of hatchling populations can vary depending upon the geographic location or the time of year (i.e., incubation temperature) the eggs are laid. In theory, an immature stage of a sea turtle population has not developed such behavior biases and is thus more likely to reveal the actual sex ratio for that population. In addition, the benthic immature life stage represents a condensation of many years of hatchling production (Wibbels et al., 1987). Interestingly, most sex ratios of sea turtle populations described to date have been fairly close to 1:1, or up to a bias of about 1.9:1 (Owens, 1996).

Foraging takes place on several kinds of benthic algae (Acanthophora, Hypnea, Codium, Amansia) as well as Halophila hawaiiana, the sole sea grass in the Hawaiian Islands. Green turtles in Kaneohe Bay rest underwater in muddy channel bottoms and in crevices associated with patch-reef pinnacles and other calcareous habitats (Brill et al., 1995). Numerous smooth depressions and undercuts have been created in the coral from repeated use by resting turtles. Buoyant fecal pellets from turtles inhabiting Kaneohe Bay regularly wash ashore, occasionally in great numbers (Balazs et al., 1993).

Additionally, none of the work reported to date has taken place in the Pacific region (Byles and Swimmer, 1994, Groshens and Vaughn, 1994). In the Hawaiian Islands the hawksbill, known as honu'ea, is a rare and endangered species (Balazs, 1978; Balazs et al. 1992; 1994). An estimated total of not more than 30 females nest in the best of years at 10 beach sites found exclusively on the islands of Hawaii, Maui, Molokai and Oahu.

Although several infectious agents (herpesvi-rus, retrovirus and papillomavirus) have been associated with the condition, the etiologic agent has not been isolated or characterized. FP has been reported worldwide in green turtles and it has been recently reported in other turtle species, including loggerheads (Caretta caretta) in Florida and olive ridleys (Lepidochelys olivacea) from the Pacific coasts of Mexico and Costa Rica. Normal skin (6) and tumor (41) biopsies were collected from 25 adult female olive ridleys in Ostional, Costa Rica, between July and September 1997. Grossly, biopsies were small, white to grey, smooth to verruciform, raised masses on the integument of the neck and flippers. All 41 masses were 25 mm or less in diameter and histologically, 8/41 masses were small foci of chronic active dermatis and not tumors; and 33/41 were diagnosed as fibropapillomas. Twelve of 33 tumors were regressing and 9 of the remaining 21 tumors had early histological changes that suggested degeneration within the tumor. During field surveys based on gross lesions, prevalences of 1-10% have been reported in this nesting population. This is considered the first diagnostic confirmation of FP in olive ridley turtles.

These HSI modeling methods are based on an approach developed by the U.S. Fish and Wildlife Service which calculated the value of an area by determining what a species needed from its habitat, followed by quantification of habitat availability. SEA Division has adapted this approach to address estuarine and marine issues, adding a spatial component utilizing GIS technology. This Kemp's ridley HSI model represents an exploratory analysis of the potential use of HSI in sea turtle management and speculative distribution and density research using currently available data.

Such turtles have been referred to as "Barnacle Bills". However, no evidence has been presented to link epibiota load and health status conclusively. During November 1997, 56 loggerhead sea turtles, 50-70 cm SCL, were sampled from Pamlico and Core Sounds, N.C., U.S.A. Turtles were measured, barnacles were counted, epibiota were sampled to enable subsequent identification, and turtles were photographed and shell and epibiota patterns were analyzed with image analysis. Blood samples were drawn at capture and 29 blood parameters were analyzed. Hypotheses tested included (l)epibiota load does not increase as a function of turtle length, (2)epibiota load does not vary between sex in juveniles, and (3) epibiota load is not an indicator of the health of the turtle.

AN - 21096658; 11287690 AB - Surveys conducted since 1988 have underscored the importance of North Carolina's inshore waters, particularly the Pamlico-Albemarle Estuarine Complex, to juvenile loggerhead (Caretta caretta), green (Chelonia mydas), and Kemp's ridley (Lepidochelys kempii) sea turtles. Sea turtles are present in the Complex April-December. During their emigration in fall and early winter, the turtles are vulnerable to capture in pound nets set behind the barrier islands. Pound nets, as set in N.C., are a passive gear that allows turtles to feed and to surface to breathe. The Core Sound and eastern Pamlico and Albemarle Sounds area was established as a pilot index area for sea turtles in 1995, using catch rates in pound nets as an index of abundance. The feasibility and methodology was established and the fishery was sampled again during fall 1996 and 1997. The goal of this 3-yr project was to establish the area as an index abundance area to monitor, assess, and predict the status of and impacts to sea turtles and their ecosystems. The cooperation of pound net fishermen in the area provides data not only on abundance, but also on movement and demography of these populations. In additions, blood samples were utilized for analyses of health status, sex, and genetics.

The Hawaiian Archipelago includes 132 islands and reefs extending for 2400 km across the North Pacific. However, the eight main islands at the southeastern end of the chain account for nearly all coastal benthic habitats suitable for foraging and resting by post-pelagic green turtles. Adult males and females residing throughout the chain migrate to breed at isolated French Frigate Shoals (23 degree 47'N, 166 degree 12'W) situated at the mid-point of the archipelago (Balazs, 1976, 1980, 1983). Systematic monitoring at tins site for 23 consecutive seasons (1973-95) has documented an approximate threefold increase in the number of nesting females (Fig. 1). This encouraging sign of population recovery is attributed to protection extended in 1978 under the U.S. Endangered Species Act. Similar increases have been seen for immature turtles inhabiting nearshore waters of the main islands, such as reported here for Kiholo Bay.

Development of the coastal strand and the resulting placement of structures on the primary and secondary dune (or equivalent), are the first steps toward coastal armoring. Coastal armoring is exhibited in many different forms. For the purpose of this paper, and with marine turtles specifically in mind, we offer the following definition of coastal armoring. Coastal armoring is any rigid or frangible structure placed parallel to the shoreline on the upper beach with the sole purpose of protecting upland structures or property. Other structures (i.e., groins, jetties) also present threats to marine turtles and their nesting habitat, but are outside the scope of this paper.

The purpose of this study was to locate resident foraging pastures utilized by the turtles, and to determine the routes taken to reach these sites. The hawksbill is a rare and endangered species in the Hawaiian Islands where it has recently been the focus of increased research and recovery efforts. Nesting is confined to only a few beaches on the islands of Oahu, Molokai, Maui and Hawaii in the southeastern segment of the archipelago. Sightings by ocean users of immature or adult hawksbills are uncommon in marine habitats of the Hawaiian Islands. In contrast, green turtles, Chelonia mydas, are numerous and routinely encountered by divers and tour operators promoting the underwater viewing of sea turtles.

ER - TY - JOUR T1 - NESTING BEACH SURVEYS: THE IMPORTANCE OF COMPLETE DATA REPORTING AN - 21081316; 11287681 AB - Nesting beach surveys are the most widely implemented monitoring tool in use by the global sea turtle community and are an important component of a comprehensive program to assess and monitor the status of sea turtle populations. These assessments are necessary to evaluate the effects of recovery and conservation activities which are being implemented at all life history stages. Monitoring techniques employed on nesting beaches range from highly structured standardized sampling to 'snapshots' of nesting activity within a nesting season. While nesting surveys are currently widespread, the variability in techniques often hampers our ability to make meaningful assessments of the status of nesting populations. Problems may occur when attempting to assess the status of nesting populations within nesting seasons but between survey areas, between and among nesting seasons at a particular nesting site, and/or across some nesting range of a particular population or stock (e.g. within country or state). With these problems in mind, the principal purpose of this paper is to emphasize the importance of reporting complete information when presenting nesting beach survey data, in order that those data may be used appropiately for both management and research purposes.

AN - 21081298; 11287675 AB - Missing from estimates of adult population size and health of sea turtle populations are the numbers of males contributing to the next generation. Peare (1994) used genetic analysis (multi-locus minisatellite probes) to demonstrate multiple paternity in green turtle clutches at Tortuguero. Mixed reports at subsequent turtle symposia have indicated that the incidence of multiple paternity varies from species to species and perhaps location to location. This study uses microsatellites to examine the paternal contribution to loggerhead clutches laid on Melbourne Beach, FL in the summer of 1996. Blood was collected from 150 mothers, and scute biopsies were taken from 1341 offspring from 89 clutches. Samples were collected at two locations which are approximately eight kilometers apart, one within and one just north of the Archie Carr National Wildlife Refuge. The genotypes of the mothers were ascertained at four polymorphic microsatellite loci: Cc141, Ei8 (FitzSimmons et al. 1995), Cc7, and Cc117 (FitzSimmons, 1997). The two most polymorphic of these loci (Cc7 and Cc141) were then selected to estimate the levels of multiple paternity in 38 clutches.

As such it is an important habitat for sea turtles including the threatened loggerhead sea turtle (Caretta caretta). The ledges and overhangs of the reef provide the loggerhead sea turtle with protected resting spots, a bountiful resource of food, and close proximity to nesting sites on barrier island beaches. The National Oceanic and Atmospheric Administration (NOAA) manages Gray's Reef and the other national marine sanctuaries to protect their natural resources. For each sanctuary, a management plan is developed to encourage compatible public uses, and to promote scientific understanding and public awareness of the marine environment. Gray's Reef National Marine Sanctuary is located 32 kilometers (17.5 nautical miles) off Sapelo Island, Georgia and encompasses 58 square kilometers (17 sq. nautical miles) of live-bottom habitat's Reef is a submerged hard bottom (limestone) area that, as compared to surrounding areas, contains extensive but discontinuous rock outcropping of moderate (3 meters) height with sandy, flat-bottomed troughs between. The series of rock ledges and sand expanses has produced a complex habitat of caves, burrows, troughs, and overhangs that provide a solid base for the abundant sessile invertebrates to attach and grow. This rocky platform with its carpet of attached organisms is known locally as a "live bottom habitat". This topography supports an unusual assemblage of temperate and tropical marine flora and fauna. Algae and invertebrates grow on the exposed rock surfaces: dominant invertebrates include sponges, barnacles, sea fans, hard coral, sea stars, crabs, lobsters, snails, and shrimp.

AN - 80019295; 9676252 AB - Hydropic vacuolation (HydVac) of biliary epithelial cells and hepatocytes is described for 3 species of U.S. West Coast bottom fishes. Risk assessment analyses are also conducted to determine if the prevalence of this lesion increases in association with contaminant exposure and site of capture. The morphology of HydVac in starry flounder Platichthys stellatus, white croaker Genyonemus lineatus and rock sole Lepidopsetta bilineata was similar to that described in winter flounder Pleuronectes americanus from the U.S. Atlantic Coast, especially in that HydVac most commonly affected biliary epithelial cells. Hydropic vacuolation was the most prevalent liver lesion in starry flounder and white croaker captured from contaminated environments. Risk assessment analyses confirmed that the relative risk for HydVac increased with the presence of aromatic and chlorinated hydrocarbons in sediment, fish bile, and fish liver for these species. Hydropic vacuolation also frequently occurred in rock sole, but the lesion showed no clear association with contaminant exposure in this species. The types of liver lesions that were useful biomarkers of contaminant effects in fish depended on the species and this factor must be taken into account when evaluating histopathological biomarkers of response to contaminant exposure.

The radar has a pencil beam, a high power, and a wavelength of 10 cm. It transmits horizontally and vertically polarized waves alternately. The available polarimetric variables are differential reflectivity, differential phase, and correlation coefficient between orthogonally polarized returns. Two types of biological scatterers, insects and birds, are contrasted. Observed polarimetric signatures of these are compared and explained with a simple scattering model. Finally, we discuss the implications of recognizing the biological scatterers' type and the size of birds.

Operational implementation of the National Oceanic and Atmospheric Administration Forecast Systems Laboratory's Local Analysis and Prediction System (LAPS) was a key element of the OWSS. LAPS is a complete, three-dimensional data assimilation system that produced subhourly atmospheric analyses on an 8-km grid covering all the Olympic venues. The LAPS analyses also provided initial conditions to the Regional Atmospheric Modeling System (RAMS) mesoscale forecast model. RAMS forecasts were generated at least every 3 h using 8- or 2-km grids. For the first time, a comprehensive operational analysis and forecast system operated in a local NWS forecast office to support meso- beta -scale forecasts and warnings. Numerous benefits of LAPS-RAMS to the local forecast office were demonstrated. The OWSS, with LAPS-RAMS included, provided a precursory view of the enhanced operational mesoscale forecast capabilities that can be available to the NWS and other forecast offices in the near future.

Annual Statistical Summary for the 1995 EMAP-Estuaries Demonstration Project in the Carolinian Province AN - 17659730; 4466665 AB - A study was conducted to assess the environmental condition of estuaries in the EMAP Carolinian Province (Cape Henry, VA - St. Lucie Inlet, FL). A total of 87 randomly located stations was sampled from July 5 - September 14, 1995 in accordance with a probabilistic sampling design. Wherever possible, synoptic measures were made of: (1) general habitat condition (depth, physical properties of water, sediment grain-size, organic carbon content), (2) pollution exposure (sediment contaminant concentrations, sediment toxicity, low dissolved oxygen conditions in the water column, ammonia and sulfide in sediment porewater), (3) biotic conditions (diversity and abundance of macroinfauna and demersal biota, pathological disorders in demersal biota), and (4) aesthetic quality (presence of anthropogenic debris, visible oil, noxious sediment odor, water clarity). Percentages of degraded vs. undegraded estuarine area were estimated based on these various environmental indicators. The data also were compared to results of a related EMAP survey conducted in 1994 in this same region as part of a multi-year monitoring effort.

Once this process is complete, the Lake Charles NEXRAD Weather Service Office (NWSO) will assume forecast and warning responsibility for sixteen Louisiana parishes, six Texas counties, and the adjacent coastal waters. This paper serves to address this new responsibility by enhancing the forecaster's knowledge of the local severe weather climatology in the Lake Charles County Warning Area (CWA).

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - Modelling estuarine eutrophication in the context of hypoxia, nitrogen loadings, stratification and nutrient ratios AN - 17577619; 4486666 AB - Estuarine eutrophication is a serious ecological and economic problem. Hypoxic waters resulting from decomposing phytoplankton in stratified bottom-waters are often associated with estuarine eutrophication, with the degree of the phytoplankton accumulation and subsequent decomposition corresponding to the phytoplankton's density in the overlying water. In general, high phytoplankton densities occur when nutrient availability is high enough to maintain the phytoplankton population. High nutrient availabilities generally result from high nutrient loads entering estuaries from their watersheds. Therefore, the co-occurrence of stratified bottom-waters and high nutrient loadings predisposes estuaries to developing hypoxic bottom-waters. This paper presents a multinominal logistic regression model that predicts the status of estuaries as normoxic, borderline hypoxic, hypoxic and severely hypoxic based on nitrogen loadings, salinity stratifications and 'phosphorus to nitrogen' load ratios. The model was applied to 10 US Gulf of Mexico estuaries and it correctly assigned eight of the 10 estuaries to their correct eutrophication status. Summaries of each estuary's probabilities for being normoxic, borderline hypoxic, hypoxic or severely hypoxic are presented along with their modelled responses to changes in nutrient loadings. Other model results include nutrient loading reductions associated with moving hypoxic and severely hypoxic estuaries into the normoxic and borderline status. This estuarine eutrophication model follows previously developed eutrophication models for lakes which were based on similar premises and have been successfully used to develop management policies. The estuarine eutrophication modelling approach provides a platform for evaluating nutrient reduction management strategies in the context of an estuary's modelled response to proposed nutrient reductions. Therefore, the modelling approach presented here is offered in support of developing management policies concerning estuarine eutrophication.

The CSTP was initiated in 1962 at the Sandy Hook Laboratory in New Jersey under the Department of Interior's U.S. Fish and Wildlife Service (USFWS). During the late 1950's and early 1960's, sharks were considered a liability to the economy of resort communities, of little or no commercial value, and a detriment to fishermen in areas where sharks might damage expensive fishing gear or reduce catches of more commercially valuable species. Several shark attacks along the New Jersey coast at that time gave rise to public concern about a perceived shark menace. In response to that concern, a shark longline survey was conducted in 1961 from Jones Inlet, N.Y., to Cape Henlopen, Del., by laboratory staff. The objectives of that study were to determine the species composition, distribution, abundance, food habits, seasonal occurrence, and other aspects of the biology of large sharks off the middle Atlantic states.

Seagrass beds in this area form patterns ranging from continuous to semi-continuous to widely dispersed, discrete patches across a gradient of increasing hydrodynamic activity. Tidal current speeds, exposure to waves and relative water depths revealed strong correlative evidence that physical processes influenced landscape-scale (50 x 50 m range with 1 m resolution) features of seagrass beds. Some habitat attributes, such as percent cover of seagrasses, seagrass bed perimeter to area ratio, sediment organic content and percent silt-clay, declined with increasing REI and current speed. Increased aggregation of these data was observed above and below the 50% seagrass cover value, and, supported by principle components analysis, signaled an abrupt transition of environmental setting correlated with this coverage level. The 50% cover value also occurred at current speeds of similar to 25 cm s super(-1), which should be near the initiation of motion current speed for local sand sediments, and an REI of similar to 3 x 10 super(6). This coverage is also near to the 59.28% coverage value, previously determined to be where landscape elements join and below which they tend to exist as discrete patches. We hypothesize that a rapid loss of seagrass habitat structural integrity may occur as the habitat fragments, and seagrass landscape elements become isolated, contributing to the observed transition and accompanying data aggregation above and below the similar to 50% coverage level. We discuss the interaction of physical setting, disturbance, landscape contiguity and growth response by these modular plants in the production of the observed landscape patterns across these hydrodynamic gradients.

Based on in situ marking experiments, we determined that the first 3 or 4 leaves on a short-shoot are produced in less than or equal to 45 d; thereafter new leaves are formed about every 40 d. We were able to confirm this estimate of leaf plastochrone interval (leaf Pl) by examining the alternating internodal sequences resulting from differential growth of the vertical stems. Analysis of short-shoot age in leaf Pl versus frequency histograms also indicated that each short-shoot produces approximately 12 leaves during the first year of growth and 9 leaves each year thereafter. Short-shoot age is skewed toward younger ages, with a median short-shoot age of approximately 0.6 yr, maximum age of 3.5 yr, and very few short-shoots living beyond 2.5 yr. Short-shoot recruitment appeared nearly continuous during the 3 yr study period. The vertical stem internodes were very large, ranging in length from 0.1 to 7.5 cm and averaging 2.1 cm. Vertical stem growth was independent of the sediment surface, raising photosynthetic tissue 25 to 60 cm above the sediments and forming a multidimensional shoot canopy at an average rate of 17 cm yr super(-1). We determined that during the first year of life short-shoots could produce upwards of 25 cm of vertical stem. The vertical stem growth rate of S. filiforme is, therefore, among the highest reported for any species of seagrass. The developing techniques of seagrass demography proved to be valuable tools for analyzing the growth dynamics and population structure of S. filiforme in outer Florida Bay.

Therefore, other lesions occurring early in the histogenesis of hepatic neoplasia need to be considered as biomarkers of chemical contaminant exposure effects in monitoring studies, especially where adult fish are not available. Moreover, exposure effects may be more reliably assessed in younger fish that have not yet migrated extensively. Accordingly, livers of subadult English sole were histologically examined from nine sites in Puget Sound, WA and the same fish were assessed for contaminant exposure by measurement of fluorescent aromatic compounds (FACs) in bile, hepatic levels of polychlorinated biphenyls (PCBs) and cytochrome P4501A (CYPIA) as catalytic activity of aryl hydrocarbon hydroxylase (AHH), and hydrophobic DNA adducts in liver by super(32)P-postlabelling. Although neoplasms were rare, higher prevalences of prenoplastic, regenerative, and unique degenerative/necrotic lesions were detected in sole from contaminated sites. Prevalences of these early histopelagic biomarkers were significantly higher at the more contaminated sites, and concentration of mean biliary FACs at each capture site was a significant risk factor for most lesions, as determined by stepwise logistic regression. By this statistical method, we also demonstrated that several measures of bioaccumulation or biochemical response to contaminants were significant and near-significant risk factors for prevalences of most hepatic lesion categories. For example, mean hepatic AHH activity was a significant risk factor for prevalence of all lesion types, except neoplasms; hepatic PCB and xenobiotic-DNA adduct concentrations were significant risk factors for the most frequently detected lesion category, hepatocellular nuclear pleomorphism/megalocytic hepatosis, and the inclusive category 'any early toxicopathic lesion'. These findings further support the utility of certain non-neoplastic liver lesions as early indicators of biological damage in subadult as well as adult fish exposed to xenobiotics in the marine environment.

The global distribution of N sub(2)O production in rivers and estuaries was modeled as a function of nitrification and denitrification rates, which were related to external nitrogen (N) inputs. N loading rates were estimated as a function of environmental parameters in the watersheds using two existing models that we adapted for global databases. Model estimated export of dissolved inorganic nitrogen (DIN) by world rivers to estuaries in 1990 is 20.8 Tg N yr super(-1); approximately 75% is estimated to be anthropogenic. DIN export to the Atlantic and Indian Oceans is similar (5.4 Tg N yr super(-1) and 4.6 Tg N yr super(-1), respectively); inputs to the Pacific are approximately 50% greater. China and southeast Asia account for over 50% of DIN export by world rivers. Globally, anthropogenic DIN export is predominately attributed to fertilizer N, followed by sewage and atmospheric deposition. About 8% of the total N inputs to the terrestrial environment can be accounted for as DIN export by rivers. Worldwide N sub(2)O emissions from rivers (55%), estuaries (11%), and continental shelves (33%) are calculated to be 1.9 Tg N yr super(-1). For rivers and estuaries, approximately 90% of N sub(2)O emissions are in the northern hemisphere in line with the regional distribution of DIN export by rivers. China and India account for about 50% of N sub(2)O emissions from rivers and estuaries. About 1% of the N input from fertilizers, atmospheric deposition, and sewage to watersheds is lost as N sub(2)O in rivers and estuaries. Globally, rivers and estuaries could account for approximately 20% of the current global anthropogenic N sub(2)O emissions and are similar in magnitude to a number of previously identified sources including direct emissions of N sub(2)O from soils induced by anthropogenic N inputs.

Restoration Project 96012A-2. EXXON VALDEZ Oil Spill. Restoration Project Final Report AN - 17164973; 4467788 AB - In Prince William Sound, predation by killer whales occurs on at least three injured resources: harbor seals (Phoca vitulina), salmon (Onchorhynchus sp), and herring (Clupea pallasi). To predict the relative impact that killer whale predation may have on these injured resources, the level of predation and the relative proportion of each species consumed by killer whales must be quantified. Current information on the feeding habits of killer whales are based either on observatons of feeding events or examination of stomach contents of stranded whales. The current paradigm is that transient whales feed primarily on marine mammals and that resident whales feed on fish. The objective of the present study was to assess whether stable isotope signature analysis and fatty acid signature analyses could be applicable in the resolution of this problem. This preliminary attempt was designed to ascertain whether standard biopsy samples, which are commonly derived for genetic analysis, would be appropriate for use in the assessment of feeding habits using these techniques.

These rates (r sub(2M)) are used as a measure of the relative ability of different sharks to recover from fishing pressure. The method incorporates concepts of density dependence from standard population modelling and uses female age at maturity, maximum reproductive age, and average fecundity. A compensatory response to population reduction is assumed in pre-adult survival to the extent possible given the constraints of the life-history parameters. 'Rebound' productivity was strongly affected by age at maturity and little affected by maximum age. Species with lowest values (r sub(2M) 0.08) were small coastal, early-maturing species. Sharks with mid-range values (r sub(2M) = 0.04-0.07) were mostly large (> 250 cm maximum size) pelagic species, relatively fast growing and early maturing. Possible selection pressures for these three shark groups, management implications, practical applications for the derived parameter r sub(2M), and recommended areas of research are discussed.

Two common zooplankton species, the euphausiid Euphausia pacifica and the copepod Calanus pacificus, consumed diverse types of field-collected marine snow, including diatom flocs, abandoned larvacean houses, and dinoflagellate aggregates, regardless of their composition, C:N ratio, age, or the availability of alternate dispersed food. Ingestion rates of aggregates by E. pacifica increased with increasing marine snow concentration, although in situ concentrations of aggregates were not sufficient to elicit a maximum ingestion rate. Ingestion rates of aggregates by E. pacifica at higher aggregate concentrations were from 9 to 15 mu g C euphausiid super(-1) h super(-1). Assimilation efficiencies of euphausiids grazing on marine snow were 83% (dinoflagellate snow) and 64 to 75% (diatom/larvacean house snow). These results indicate that marine snow can be an important food source for marine zooplankton and that consumption of large aggregates is likely to play a role in the cycling of carbon and the structure of food webs in the pelagic zone of the ocean.

This species is harvested commercially. Shell length and age data were collected for this species from 1980 to 1994 during surveys of population size and structure. These data were used to examine the relationship between the growth rate of S. solidissima and intraspecific density. The null hypothesis was that density (represented by number of individuals per tow) would have no effect on rate of growth. A negative relationship would support the alternative hypothesis, that intraspecific competition had taken place. This analysis focused on the surfclam population offshore from the Delmarva Peninsula, USA because: (1) a major recruitment event occurred in 1977, (2) clam fishermen had reported "stunted" surfclams in that area, (3) a wide range of local densities were available to examine, and (4) the existence of a closed area within the study area set up an interesting contrast with areas left open to harvesting. Maps of surfclam abundance across the Delmarva region demonstrate that areas of highest density have generally remained in the same location through time. The results suggested that intraspecific competition has been important in structuring this population. Based on data from 1980 to 1992, shell length was significantly reduced at high density, and a significant interaction between age and density was observed. Growth modeling indicated decreased asymptotic lengths and growth rates with increasing density. In nine out of ten pairwise randomization tests, fitted von Bertalanffy growth curves, representing different densities, were significantly different from each other. High densities of clams have persisted in the area that was closed to harvesting for 11 years (1980 to 1991). In 1994, length at age was significantly less in this closed area compared to that in the surrounding area. This effect was apparent in clams from 3 to 17 years of age, and most pronounced in the cohort that recruited to the Delmarva region in high numbers in 1977. Lower growth rates within the closed area have management implications for the optimal duration of closures.

Those sequences had been used to identify the two types of Xyrichtys larvae as X. novacula, but owing to the contamination, the identifications are invalid. Fresh specimens were collected: X. martinicensis (Curvier and Valenciennes), X. novacula, X. splenders (Castelnau), and Xyrichtys sp. larvae of each of the two morphotypes (dorsal-forward eye and ventral-forward eye). The cytochrome b fragment was amplified from each specimen using the polymerase chain reaction. Comparison of the sequences with human cytochrome b sequence confirmed that the new sequences were not contaminated. The interspecific differences in Xyrichtys sequences were less than previously reported, but still greater than observed in many fish genera. Distance and parsimony analyses indicated that X. novacula and X. martinicensis were more closely related to each other than to X. splendens. This conclusion differs from our previous conclusion that X. martinicensis and X. splendens were more closely related to each other than to X. novacula. Distance and parsimony analyses also demonstrated that both larval morphotypes were X. novacula and, thus, our previous conclusions regarding larval ecology and oceanographic transport remain unchanged.

Changes in fish health bioindicators after 90 days, i.e., increases in fin erosion, liver lipidosis, gill hyperplasia, and gill parasites, coupled with decreases in macrophage aggregates, occurred at hydrocarbon concentrations (1600 mu g/g) that reduced growth 34-56% among the flatfishes. Chronic hydrocarbon pollution of nearshore nursery sediments could alter growth and health of juvenile flatfishes. Recruitment of juveniles to the fishery may decline because of increased susceptibility to predation and slower growth.

Age-0 walleye pollock Theragra chalcogramma appeared to be frequently associated with these gelatinous zooplankton. During daytime, up to 30 pollock were observed swimming within the tentacles of these medusae, but when approached by the ROV, the pollock generally left the vicinity of the jellyfish. At night, few such associations were observed and juvenile pollock moved closer to the surface, apparently feeding in loose aggregations, while the medusae remained close to the thermocline (35-40 m). Prowfish Zaprora silenus were also observed near large medusae, but tended to be found closer to the bell rather than within the tentacles. The lack of any gelatinous material in the stomachs of the pollock suggests that juvenile pollock associate to gain shelter from predation or possibly as a thigmotactic response to biotic structure. The implications of this commensal behavior with gelatinous zooplankton are discussed relative to pollock recruitment in the Eastern Bering Sea.

Experiments were performed at the Organization for Tropical Studies (OTS) Palo Verde Biological Station (10 degree N, 85 degree W), Guanacaste Province, Costa Rica during the dry season on 13-14 February 1993. Acacia collinsii, Pseudomyrmex spinicola, P. nigrocinctus, and P. flavicornis are common in dry sites near the biological station. Only trees with a diameter at breast height of at least 3 cm were used because they had sufficiently established ant colonies. Trees of the proper size were selected haphazardly by flagging the first 42 trees with separate Pseudomyrmex spinicola or P. nigrocinctus colonies and the first 42 trees with separate P. flavicornis colonies that were encountered.

The precipitation anomaly over the west coast of North America shows a north-south three-cell pattern. Heavy precipitation in California is accompanied by dry conditions over Washington, British Columbia, and along the southeastern coast of Alaska and reduced precipitation over the subtropical eastern Pacific. The inverse relationship between California and the Pacific Northwest is supported by the transport of moisture flux. During wet events, the southern branch of moisture flux transport strengthens and brings moisture from the North Pacific to California, hence enhanced rainfall. Strengthened moisture flux transport northward to the area north of Washington is consistent with suppressed rainfall in California. The local precipitation anomaly pattern in the eastern tropical Pacific just north of the equator has a large influence on precipitation events in California. The enhanced precipitation generates strong rising motion. The associated sinking motion is located over California. Strong sinking motion and strong upper-level convergence favor dry conditions in California. Conversely, suppressed rainfall in the eastern Pacific is associated with above-normal precipitation in California. Precipitation in California is likely below normal during cold ENSO events. When convection in the central Pacific is enhanced, California has heavy precipitation if rainfall in the subtropical eastern Pacific is suppressed. In addition to ENSO, precipitation in California is also modulated by the tropical intraseasonal oscillation. Wet (dry) events are favored during the phase of the oscillation associated with enhanced convection near 150 degree E (120 degree E) in the tropical Pacific.

Criteria for sewage sludge acceptability for land application are bulk chemical concentrations. Criteria for acceptability of dredged material for disposal at sea focus upon biological testing for toxicity and bioaccumulation. The result is that sludge applied to land can have much higher levels of contamination than are commonly found even in sediments deemed unacceptable for disposal-at-sea. The inconsistencies between these criteria suggest re-evaluations of both.

School mackerel spawned along the Queensland coastline from October to January. Female school mackerel were sexually mature between 401 and 450 mm, and males between 351 and 400 mm LCF (length to caudal fork). In contrast, spotted mackerel spawned in northern Queensland waters from August to October. Females were between 451 and 500 mm, and males 401 and 450 mm LCF at first maturity. Both species were found to be dioecious. Differential spawning patterns of school and spotted mackerel may help the species coexist and maintain the integrities of the species and their respective stock structures.

A 16-residue Omega -loop deletion mutant of beta -lactamase from Staphylococcus aureus PC1, encompassing residues 163-178, was produced in order to examine the functional and structural role of the loop. The crystal structure was determined and refined at 2.3 angstrom, and the kinetics of the mutant enzyme was characterized with a variety of beta -lactam antibiotics. In general, the wild-type beta -lactamase hydrolyzes penicillin compounds better than cephalosporins. In contrast, the deletion of the Omega -loop led to a variant enzyme that acts only on cephalosporins, including third generation compounds. Kinetic measurements and electrospray mass spectrometry revealed that the first and third generation cephalosporins form stable acyl-enzyme complexes, except for the chromogenic cephalosporin, nitrocefin, which after acylating the enzyme undergoes hydrolysis at a 1000-fold slower rate than that with wild-type beta -lactamase. Hydrolysis of the acyl-enzyme adducts is prevented because the deletion of the Omega -loop eliminates the deacylation apparatus comprising Glu166 and its associated nucleophilic water site. The crystal structure reveals that while the overall fold of the mutant enzyme is similar to that of the native beta -lactamase, local adjustments in the vicinity of the missing loop occurred. The altered beta -lactam specificity is attributed to these structural changes. In the native structure, the Omega -loop restricts the conformation of a beta -strand at the edge of the active site depression. Removal of the loop provides the beta -strand with a new degree of conformational flexibility, such that it is displaced inward toward the active site space. Modeled Michaelis complexes with benzylpenicillin and cephaloridine show that the perturbed conformation of the beta -strand is inconsistent with penicillin binding because of steric clashes between the beta -lactam side chain substituent and the beta -strand. In contrast, no clashes occur upon cephalosporin binding. Recognition of third generation cephalosporins is possible because the bulky side chain substituents of the beta -lactam ring typical of these compounds can be accommodated in the space freed by the deletion of the Omega -loop.

The rivers Figgjo and North Esk are relatively small salmon rivers in southern Norway and eastern Scotland, respectively. Wild salmon smolts have been tagged in these rivers since 1965. Tag returns were used to evaluate the survival of salmon in the North Sea. Survival rates of one-sea-winter (1SW) and 2SW fish were correlated within stocks, as well as between stocks. Survival rates were compared with the areal extent of thermal habitat in the north-eastern Atlantic Ocean. A positive correlation was found between the area of 8-10 degree C water in May and the survival of salmon. A reciprocal negative correlation was also found between survival and 5-7 degree C water in the same month. An analysis of sea surface temperature distributions for periods of good vs. poor salmon survival showed that when cool surface waters dominate the Norwegian coast and North Sea during May, salmon survival has been poor.

The rate of grazing damage experienced by submersed and floating leaves of water lilies (Nuphar variegata and Nymphaea odorata) was monitored in lakes in the Upper Peninsula of Michigan, U.S.A. Herbivores damaged 0.2-1.7% of the leaf surface of water lilies per day. These grazing rates differed between plant species, between submersed and floating leaves, and between lakes. Some leaves had more than 60% of their surface damaged and an overall mean of 16% damage occurred during the 2-3 week monitoring period of this study. 2. Snapshot measurements of grazing damage on randomly collected submersed and floating leaves of Nuphar showed that submersed leaves were more damaged (11.0 plus or minus 1.6%, n = 84) than floating leaves (3.8 plus or minus 0.6%, n = 92). Overall, these 176 Nuphar leaves had 7.2% of their area damaged. 3. Five species of herbivorous insects were commonly found on water lilies (Nymphaeacea). One primarily aquatic insect (sensu Newman, 1991), a caddisfly larva (Trichoptera: Limniphilidae), had a generalized diet of water lilies, other macrophytes, algae, and detritus. Four of the five insects were from primarily terrestrial insect groups (Coleoptera and Diptera; 'secondary invaders', sensu Newman, 1991) and consumed only water lilies in food preference experiments. 4. The feeding preferences of the generalist trichopteran were altered when the macrophytes were freeze-dried, ground into a powder, and reconstituted in an alginate gel. This suggests that plant structure may be an important feeding determinant for this insect. In contrast, a specialist weevil preferred its host plant in choice assays, regardless of whether fresh tissue or reconstituted macrophytes were used, suggesting this insect cued on a unique, non-structural property of its host plant. 5. These results suggest that herbivory on freshwater macrophytes is of a similar magnitude to that on terrestrial plants. The findings of this study are consistent with the hypothesis that herbivorous insects of primarily terrestrial groups have a narrower diet breadth than insects of primarily aquatic groups.

The 19F4 firefighting trainer is an elevated platform or deck with a central region composed of steel grating above propane burners. High winds could push flames below the grating, creating a personnel and equipment hazard. By simulating the trainer with computational fluid dynamics (CFD), scientists from the National Institute of Standards and Technology (NIST) identified the problem - a low-pressure zone below the grating. These dynamics were then used to evaluate the effectiveness of a variety of proposed solutions. The original problem surfaced on the firefighter trainer at the San Francisco Bay Treasure Island naval base. Wind blowing into the bay forced the flames beneath the trainer deck, where they could have damaged instruments and cabling. Wind also stretched the flames into the stairway opening onto the deck. The Navy had tried several experiments to block the wind with steel skirts that rose to deck level around the trainer, but this made the problem worse. Though constructing a building to enclose the trainer was another option considered, this would have been an expensive solution. So the Navy asked for suggestions from the NIST Fire Modeling and Applications Group, which develops and applies mathematical models to fire growth and smoke spread. The group uses three modeling approaches to predict the course of a fire: simple models (back of the "crt"), zone models, and CFD models. The zone model concept is embodied in the CFAST/HAZARD I model, which can predict the time-evolving smoke distribution and fire gases, and the temperature throughout a building during a user-specified fire. HAZARD I combines CFAST with additional capabilities to analyze hazards for various applications.

Although their life cycles are similar, evidence indicates that the species utilize different resources for the primary faunal element of their diets. Prey selection and growth studies have shown that brown shrimp successfully remove infauna from natural sediment. Further, a diet of polychaetes, whether alone or in combination with algae, produced growth in the species. Brown shrimp appear to be trophically linked to infaunal populations, thus the structure and dynamics of the benthic community may directly affect local brown shrimp productivity. Areas dominated by surface-dwelling polychaetes as opposed to deep burrowers may provide more accessible foraging opportunities for juvenile brown shrimp. By contrast, white shrimp neither removed infauna nor grew to a significant degree when provided polychaetes or amphipods as food. White shrimp are omnivorous but do not rely on infaunal material to the same extent as brown shrimp. The primary faunal element in the diet of white shrimp has not yet been identified. The dietary differences between the two species may play a role in determining which species dominates in regions with varying marsh accessibility. Although not the only factors influencing penaeid survival and growth, prey choice and availability may greatly affect production and local success of penaeid populations.

Acetylene reduction (AR) assays were conducted over a 24-mo period to estimate N sub(2) fixation rates on standing dead stems and leaves. In the natural salt marsh, mean AR rates ranged from 0.5 nmol C sub(2)H sub(4) cm super(-2) h super(-1) to 14 nmol C sub(2)H sub(4) cm super(-2) h super(-1), while in the transplanted marsh mean AR rates ranged from 1 nmol C sub(2)H sub(4) cm super(-2) h super(-1) to 33 nmol C sub(2)H sub(4) cm super(-2) h super(-1). Diel AR activity of epiphytic communities in both marshes varied seasonally. Midday incubations yielded higher AR rates than nighttime incubations in the spring, while midday incubations in late summer and fall generally yielded AR rates equal to or lower than nighttime incubations. Desiccation during low tides occasionally repressed AR activity, although AR rates quickly rebounded with wetting. AR activity was localized in the epiphytic community, rather than in the underlying Spartina stem material. Based on the measured AR rates and the density of standing dead stems, the annual input of new N to the natural salt marsh via epiphytic N sub(2) fixation is estimated to be 2.6 g N m super(-2) yr super(-1). The estimate of annual input of new N to the transplanted marsh is 3.8 g N m super(-2) yr super(-1). These estimates should be added to previous estimates of N sub(2) fixation in marsh sediments to estimate the total contribution of new nitrogen to salt marsh nitrogen budgets.

Over the past 100 years, there has been substantial urban and industrial development within this region, resulting in heavy inputs of chemical contaminants at selected sites, as well as significant loss or alteration of marine habitat. Studies show that feral flatfish in Puget Sound are experiencing a range of biological effects due to chemical contaminant exposure, including reproductive dysfunction, altered immune competence, and development of toxicopathic diseases, and there is some evidence of reduced survival in fish from urban areas of Puget Sound from increased infectious and toxicopathic disease. Puget Sound sole are also subject to other anthropogenic stressors, such as fishing pressure or alteration of nearshore nursery habitats. The cumulative impact of these stressors on flatfish abundance in Puget Sound, however, is poorly understood. In a series of field and laboratory studies, we determined vital rates and other life history parameters in English sole (Pleuronectes vetulus) subpopulations from urban and non-urban sites in Puget Sound, and are using this information to estimate potential population level impacts of anthropogenic stressors, with age and stage-based Leslie-matrix models. Initial results suggest that declines in the fecundity component of the model, as observed in field studies of fish from contaminated sites, could reduce the size of sub-populations in these areas if the loss of recruits is not offset by density-dependent changes in recruitment, immigration, or other compensating mechanisms. Studies on flatfish species from a variety of sites in Europe and North America suggest that contaminant-related disease and reproductive impairment are widespread in this group of fish, although substantial differences in sensitivity have been observed, even among closely related species. Comparative studies with a variety of Pleuronectid species will enable us to better evaluate the risk posed by anthropogenic stressors to flatfish, and contribute to improved assessment and management of this important fisheries resource.

The southern two-thirds of the island has an average width of eight miles, while the northern third consists of a narrow spur with an average width of one mile. The interior portion of the island is largely uninhabited partly because of limited access via land transportation systems. Existing roads connecting settlements on the island consist of dirt, gravel, or crushed coral surfaces. Three alternatives are considered in this revised draft EIS; the No Action Alternative was eliminated because it would fail to address existing practices and conditions which have a damaging effect on the environment. Under the preferred alternative, a loop system would be constructed in the southern two-thirds of the island and a single spur on the more narrow northern portion. The 53 miles of roadways would connect all ten states on the island and bypass existing settlements instead of running through them. Therefore, the roadway system would need to be complemented by secondary roads connecting to existing settlements. The construction of the roadway would be jointly funded by the U.S. government and the government of Palau. POSITIVE IMPACTS: Under the preferred alternative, the project would provide island-wide access to all settlements while minimizing disturbance to existing communities. The road would also provide access to areas with potential for agriculture, forestry, mining, industry, and tourism, and near watersheds for future water resource development, rock sources for quarries, and port development sites. The road would provide residents of the island an opportunity to live on their land and commute to work in Koror, rather than having to rent additional living quarters at or near Koror, as is now the practice. The project would generate 1,600 jobs per year in construction-related work and 3,088 indirect jobs. NEGATIVE IMPACTS: The economic development expected to result from roadway construction would gradually erode a traditional way of life. Land-disturbing activities could adversely affect geology and topography, soils, water quality, air quality, noise levels, flora, fauna, and coastal, marine, and estuarine resources.

AN - 36403737; 6776 AB - PURPOSE: The designation of Monterey Bay and its adjacent waters, and the submerged lands thereunder, off central California, as a national marine sanctuary is proposed. Under the preferred boundary alternative, the sanctuary would encompass an area of approximately 4,024 square nautical miles in and surrounding Monterey Bay, and would extend along 362 nautical miles of shoreline. Federal and state waters would account for 83 percent and 17 percent, respectively, of the sanctuary. The northern terminus of the sanctuary boundaries would be located along the southern boundary of the Gulf of Farallones National Marine Sanctuary and run westward to approximately the 500 fathom isobath. The boundary line would then extend southward in an arc, following the 500 fathom isobath to a point due west of Cambria. The boundary line would then extend shoreward toward the mean high-water line. The landward boundary would be defined by the mean high-water line between the Gulf of Farallones National Marine Sanctuary and Cambria, exclusive of a 71-square-mile area off the north coast of San Mateo County and the city and county of San Francisco, between Point San Pedro and Point Bonita. Under the preferred alternative, new regulations would be promulgated to govern hydrocarbon activities, discharges and deposits, overflights by low-flying aircraft, the alteration of or construction on the seabed, historical resources, personal watercraft, and marine mammals, turtles, and seabirds. To aid in the enforcement of these regulations, additional regulations would prohibit the possession of resources and the interference with enforcement efforts. These regulations would allow limited, small-scale collection of loose jade found in the Jave Cove area, a series of small coves located south of Big Sur, near Gorda, California. This final supplement to the final EIS of June 1992 considers the environmental effects of this exception. POSITIVE IMPACTS: The designation of the Monterey Bay area as a national marine sanctuary would provide for an integrated program of resource protection, research, and education. Resource protection would involve cooperation with other agencies to assure appropriate implementation of policies and procedures. Through education, public awareness of the value of this area would be enhanced. Sanctuary management would result in the maintenance or improvement of the water quality, fishery resources, and aesthetics of the area. The collection of loose jade, a popular tourist activity, would be allowed to continue under the proposed exception. NEGATIVE IMPACTS: Permit, license, and lease costs would affect local users of the sanctuary. Regulations covering discharges and deposits could result in more substantial cost increases for users. Revenue associated with oil, gas, and mineral activities, all of which would be prohibited under the management plan, would be foregone.

This relationship is further reconfirmed by the 14 C measurements from large volume samples taken in the deep waters in the Pacific Ocean during the recent WOCE survey program. Analysis of upper ocean 14 C measurements made along 152 degree W, and north of 20 degree N, in the northeastern Pacific Ocean during the NOAA's CGC91 cruise, which is a part of the WOCE survey program, indicates that the bomb 14 C inventory in this part of the ocean has increased by 22% since the GEOSECS measurements made in 1974. This increase is consistent with the model prediction of 25% for the Northern Hemisphere ocean. Change of the surface water bomb Delta 14 C values during this period is insignificant. This feature is also consistent with the model simulation. Results of this new analysis will provide useful information of the temporal variations of bomb 14 C inventory in the ocean, in addition to the spatial distribution, which can be used as powerful constraints in calibrating the global ocean carbon cycle models, especially those based on three-dimensional ocean general circulation models, for estimating the uptake of CO 2 by the ocean.

Although these techniques provide excellent performance for masses up to about 20,000 daltons, there has been limited success in achieving good mass resolution at higher masses. This is because the sensitivity of the microchannel plate (MCP) detectors used in most systems decreases rapidly with increasing particle mass, limiting the utility of MCP detectors for very large masses. It has recently been proposed that cryogenic particle detectors may provide a solution to these difficulties. Cryogenic detectors measure the thermal energy deposited by the particle impact, and thus have a sensitivity that is largely independent of particle mass. Recent experiments,, have demonstrated the sensitivity of cryogenic particle detectors to single biomolecules, a quantum efficiency several orders of magnitude larger than the MCP detectors, and sensitivity to masses as large as 750,000 daltons. Here we present results demonstrating an order of magnitude better energy resolution than previous measurements, allowing direct determination of particle charge state during acceleration. Although application of these detectors to practical mass spectrometry will require further development of the detectors and cryogenics, these detectors can be used to elucidate the performance-limiting processes that occur in such systems.

AN - 79670428; 9457881 AB - It is demonstrated here that in Escherichia coli, the phosphorylated form of the glucose-specific phosphocarrier protein IIA(Glc) of the phosphoenolpyruvate:sugar phosphotransferase system is an activator of adenylyl cyclase and that unphosphorylated IIA(Glc) has no effect on the basal activity of adenylyl cyclase. To elucidate the specific role of IIA(Glc) phosphorylation in the regulation of adenylyl cyclase activity, both the phosphorylatable histidine (H90) and the interactive histidine (H75) of IIA(Glc) were mutated by site-directed mutagenesis to glutamine and glutamate. Wild-type IIA(Glc) and the H75Q mutant, in which the histidine in position 75 has been replaced by glutamine, were phosphorylated by the phosphohistidine-containing phosphocarrier protein (HPr-P) and were equally potent activators of adenylyl cyclase. Neither the H90Q nor the H90E mutant of IIA(Glc) was phosphorylated by HPr-P, and both failed to activate adenylyl cyclase. Furthermore, replacement of H75 by glutamate inhibited the appearance of a steady-state level of phosphorylation of H90 of this mutant protein by HPr-P, yet the H75E mutant of IIA(Glc) was a partial activator of adenylyl cyclase. The H75E H90A double mutant, which cannot be phosphorylated, did not activate adenylyl cyclase. This suggests that the H75E mutant was transiently phosphorylated by HPr-P but the steady-state level of the phosphorylated form of the mutant protein was decreased due to the repulsive forces of the negatively charged glutamate at position 75 in the catalytic pocket. These results are discussed in the context of the proximity of H75 and H90 in the IIA(Glc) structure and the disposition of the negative charge in the modeled glutamate mutants.

Pac. CO (sub 2) system data set ( nearly equal 2500 water samples) has been evaluated to assess the internal consistency of measurements and calculations involving CO (sub 2) fugacity and pH (sub T) . This assessment represents the first large scale field comparison of pH (sub T) and f (sub CO2) data. Comparisons of direct discrete CO (sub 2) fugacity (f (sub CO2) ) measurements with CO (sub 2) fugacity calculated from total inorganic carbon (C (sub T) ), total alkalinity (A (sub T) ) and spectrophotometric pH (pH (sub T) = -log[H (super +) ] (sub T) ) indicate that a variety of improvements are needed in the parameter measurements and thermodynamic relationships used to relate f (sub CO2) , C (sub T) , A (sub T) and pH (sub T) in seawater. CO (sub 2) fugacity calculated from C (sub T) and pH (sub T) or A (sub T) and pH (sub T) agree with direct measurements to no better than 1%. Comparisons of measured fugacity, f (sub CO2) (measured), and CO (sub 2) fugacity calculated from C (sub T) and pH (sub T) , f (sub CO2) (C (sub T) , pH (sub T) ), indicate that the precision of f (sub CO2) calculations is good relative to direct measurements. In contrast, due to the extreme sensitivity of f (sub CO2) and [H (super +) ] (sub T) calculations to relatively small errors in both C (sub T) and A (sub T) , CO (sub 2) fugacity, as well as [H (super +) ] (sub T) , calculated from C (sub T) and A (sub T) are very imprecise and render comparisons with direct measurements of little use. Consequently, precise calculations of f (sub CO2) require the use of direct pH (sub T) measurements.

Thus it can be used to determine dissolution of calcium carbonate (hard tissue) and remineralization of organic material (soft tissue), to quantify saturation constants of calcite and aragonite in seawater, and to characterize water masses. f (sub CO2) (20) is a good tracer of biological transformation since it is thermodynamically related to the other inorganic carbon system parameters and it has a dynamic range from 200 to 2000 mu atm in the world's ocean. Precision of f (sub CO2) measurements is 0.3% and the values are well calibrated using compressed gas reference standards. Increases of f (sub CO2) (20) are observed as the water masses age during movement from the Atlantic to the Indian and South Pacific oceans. As an example of the determination of the ratio of soft tissue remineralization to hard tissue dissolution from f (sub CO2) (20) and DIC, the trends along the 27.2 isopycnal for the subtropical gyres of the three basins are investigated. Little CaCO (sub 3) dissolves along this isopycnal in the Atlantic and the South Pacific while the soft tissue remineralization to hard tissue dissolution ratio in Indian Ocean is 4.5:1. The difference in this ratio along the 27.2 isopycnal appears to be a combination of the calcite and aragonite saturation levels and the supply of aragonite tests.

Aircraft cloud samples were taken not only by traditional two-dimensional probes but also by using a new video sampler to account for small particles. The cloud parameter comparisons were made for time intervals when aircraft were passing approximately above ground-based instruments that were pointed vertically. Comparing characteristic particle sizes expressed in terms of median mass diameters of equal-volume spheres yielded a relative standard deviation of about 30%. The corresponding standard deviation for the cloud ice water content comparisons was about 55%. Such an agreement is considered good given uncertainties of both direct and remote approaches and several orders of magnitude in natural variability of ice cloud parameters. Values of reflectivity measured by the radar and calculated from aircraft samples also showed a reasonable agreement; however, calculated reflectivities averaged approximately 2 dB smaller than those measured. The possible reasons for this small bias are discussed. Ground-based and aircraft-derived particle characteristic sizes are compared to those available from published satellite measurements of this parameter for the cirrus priority case from FIRE-II. Finally, simultaneous and collocated, ground-based measurements of visible (0.523 nm) and longwave IR (10-11.4 km) ice cloud extinction optical thickness obtained during the 1995 Arizona Program are also compared. These comparisons, performed for different cloud conditions, revealed a relative standard deviation of less than 20%; however, no systematic excess of visible extinction over IR extinction was observed in the considered experimental events.

This observation by a recent WHO report further stated that in the U.S. alone, there are between 3.3 and 12.3 million cases, and up to 3,900 deaths each year. Microbiological hazards have often become perceived as controllable, and erroneously accepted as familiar old adversaries tamed by modern technology and magic bullets. The consumer and food producer may sometimes give perfunctory attention to sanitary practices, until specific outbreak incidents occur, with highly focused media coverage. Ironically the relatively recent success at reducing diseases from microorganisms has lulled us to complacency about the simplest sanitary measures that have contributed so significantly to their initial control. Although the final critical control point for many food borne diseases is dependent upon the food handling care and knowledge within the final preparation area. Maintenance of sanitary hygienic standards is a serious responsibility for everyone in the food production process. The final regulation Part 123.11 (a) recommends that each processor should have and implement a written sanitation standard operating procedure (SSOP) or similar document that is specific to each location where fish and fishery products are produced. The SSOP places a responsibility on the processor for identifying relevant sanitary controls on conditions that can introduce food safety hazards or cause adulteration of the product. The processor must also maintain sanitation control records that, at minimum, document the monitoring and corrections prescribed in the rule. Additionally as aquaculturists, sanitary practices and hygienic measures are also the baseline defense for avoiding, seducing, or controlling microbiological pathogens in the environment or populations of animals. As mundane as such basic principles like isolate, clean, disinfect, and control access of animal stock, materials and visitors, may be, they remain at the heart of the animal health program that will control the most likely disease causing hazards for either human or animal health.

Data for the years 1948- 1994 was compiled using the NCEP Version III Grid Point Data Set. Patterns were examined during the time of heaviest snow, and composites made of 5 distinct flow patterns. The five flow patterns composited were: Southwest Flow, Amplified Southwest Flow, West Flow, Northwest Flow, and Closed Low. Conposites were obtained by using the GEMCD program. Fields chosen for the composites were: 500 mb heights, Mean Sea-Level Pressure (MSLP), and 250 mb winds. To isolate the heavier snowfalls, separate composites were performed for single day totals of 5-9 inches. Single day snows of 10+ inches were rare, so they were examined individually.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - Secular Trends of Precipitation Amount, Frequency, and Intensity in the United States AN - 17253313; 4542071 AB - Twentieth century trends of precipitation are examined by a variety of methods to more fully describe how precipitation has changed or varied. Since 1910, precipitation has increased by about 10% across the contiguous United States. The increase in precipitation is reflected primarily in the heavy and extreme daily precipitation events. For example, over half (53%) of the total increase of precipitation is due to positive trends in the upper 10 percentiles of the precipitation distribution. These trends are highly significant, both practically and statistically. The increase has arisen for two reasons. First, an increase in the frequency of days with precipitation ]6 days (100 yr) super(-1) [has occurred for all categories of precipitation amount. Second, for the extremely heavy precipitation events, an increase in the intensity of the events is also significantly contributing (about half) to the precipitation increase. As a result, there is a significant trend in much of the United States of the highest daily year-month precipitation amount, but with no systematic national trend of the median precipitation amount. These data suggest that the precipitation regimes in the United States are changing disproportionately across the precipitation distribution. The proportion of total precipitation derived from extreme and heavy events is increasing relative to more moderate events. These changes have an impact on the area of the United States affected by a much above-normal (upper 10 percentile) proportion of precipitation derived from very heavy precipitation events, for example, daily precipitation events exceeding 50.8 mm (2 in.).

In response to this petition and the more general concerns for the status of Pacific salmon throughout the region, NMFS announced that it would initiate ESA status reviews for all species and populations of anadromous salmonids in the states of Washington, Idaho, Oregon, and California. Subsequently, NMFS received a petition (ONRC and Nawa 1995) to list all chinook salmon south of British Columbia under the ESA. The ESA allows the listing of 'distinct population segments' of vertebrates as well as named species and subspecies. The policy of the NMFS on this issue for anadromous Pacific salmonids is that a poulation will be considered 'distinct' for purposes of the ESA if it represents an evolutionarily signfiicant unit (ESU) of the species as a whole.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - How habitat degradation through fishery disturbance enhances impacts of hypoxia on oyster reefs AN - 16522140; 4364457 AB - Oysters are ecosystem engineers that create biogenic reef habitat important to estuarine biodiversity, benthic-pelagic coupling, and fishery production. Prevailing explanations for the dramatic decline of eastern oysters (Crassostrea virginica) during the last century overlook ecosystem complexity by ignoring interactions among multiple environmental disturbances. To explain oyster loss, we tested whether (1) mortality of oysters on natural oyster reefs varies with water depth (3 m vs. 6 m), (2) harvesting by oyster dredges reduces the height of oyster reefs, and (3) bottom-water hypoxia/anoxia and reduction in reef height through fishery disturbance interact to enhance mortality of oysters in the Neuse River estuary, North Carolina, USA. The percentage of oysters found dead (mean plus or minus 1 SD) during a survey of natural reefs in May 1993 was significantly greater at 6-m (92 plus or minus 10%) than at 3-m (28 plus or minus 9%) water depth. Less than one season's worth of oyster dredging reduced the height of restored oyster reefs by similar to 30%. During stratification of the water column in summer, oxygen depletion near the seafloor at 6 m caused mass mortality of oysters, other invertebrates, and fishes on short, deep experimental reefs, while oysters and other reef associates elevated into the surface layer by sufficient reef height or by location in shallow water survived. Highly mobile blue crabs (Callinectes sapidus) abandoned burrows located in hypoxic/anoxic bottom waters but remained alive in shallow water. Our results indicate that interaction of reef habitat degradation (height reduction) through fishery disturbance and extended bottom-water hypoxia/anoxia caused the pattern of oyster mortality observed on natural reefs and influences the abundance and distribution of fish and invertebrate species that utilize this temperate reef habitat. Interactions among environmental disturbances imply a need for the integrative approaches of ecosystem management to restore and sustain estuarine habitat.

Feeding regimes yielding the highest conversion efficiencies of algal feed to molluscan growth are required to maximize the return on algal-culture investments. In the past we have used 12 specialized, manually-controlled molluscan rearing chambers to study nutritional requirements and growth of oysters, clams, and scallops. A computer-controlled, solenoid-valve system was added to automate seawater flow, volume of microalgal food delivered, and feeding duration independently for each chamber. Labor was reduced from 7 h per week to 3 h, while adding flexibility. Each chamber represents a model for a programmed nursery system. Evidence that superior growth of bivalves can be achieved by feeding regimes made possible by this apparatus are provided by an experiment with juvenile bay scallops (Argopecten irradians).

The taxonomic composition and size of prey found in the stomachs of age-0 juveniles collected at three nearshore locations in the Gulf of Alaska in September 1990 were compared to the composition and size of zooplankton collected in concurrent plankton tows. The maximum length of prey consumed increased dramatically over the length range of pollock examined (58-110 mm) from approximately 7 mm to 30 mm, due mainly to the consumption of large euphausiids and chaetognaths by the bigger individuals. The maximum width of prey changed little over this size range although there was a general increase in prey width with increasing predator size. The minimum prey length and width did not change with increasing fish size. Juvenile pollock generally selected the larger prey sizes relative to what was available. Juvenile pollock showed a marked preference for adult euphausiids and decapod larvae and an avoidance of copepods and chaetognaths relative to the numbers collected in net tows. These results are discussed relative to the feeding ecology of these juvenile fishes.

The Standardized Precipitation Index (SPI) was recently developed to quantify a precipitation deficit for different time scales. It was designed to be an indicator of drought that recognizes the importance of time scales in the analysis of water availability and water use. This study compares historical time series of the PDI with time series of the corresponding SPI through spectral analysis. Results show that the spectral characteristics of the PDI vary from site to site throughout the U.S., while those of the SPI do not vary from site to site. They also show that the PDI has a complex structure with an exceptionally long memory, while the SPI is an easily interpreted, simple moving average process.

After 96-h exposures, malathion was most toxic to newly hatched larvae with an LC 50 of 9.06 mu g/l followed by an LC 50 of 13.24 mu g/l for 18-day-old larvae and an LC 50 of 38.19 mu g/l for adult shrimp. In a separate bioassay, to simulate field conditions, newly hatched larvae were exposed to malathion at 6 h/day every 5 days at a salinity of 10ppt until metamorphosis to postlarvae. After four pulse dose exposures, mortality was highest in the two highest concentrations, of 15.0 and 30.0 mu g/l. The number of instars to postlarvae was significantly lower in the highest concentration compared to control. The findings indicate that malathion may not directly affect growth in a measurable way but may alter natural metamorphic rhythms at the highest concentrations. Whole body acetylcholinesterase (AChE) activity was measured on Day 0 and Day 15 from the pulse exposure test. AChE activities were not significantly different from controls. Other factors than just AChE inhibition may have contributed to malathion toxicity.

The two facilities, which are located in different parts of Juneau, collaborate in the development of fishery management policies and regulations for the fisheries off the Alaska coast. The ARO is located in rented General Services Administration office space in the federal building in downtown Juneau. The ABL, which provides the scientific research needed to support fishery management decisions, is located on a 3.5-acre site located 12 miles northwest of Juneau. Five alternatives, including a No Action Alternative, are considered in this final EIS. The preferred alternative would involve constructing a facility on a 22-acre site at Lena Point that is currently operating as a rock quarry owned and operated by SECON, Inc. According to the terms of a land trade under consideration, the NMFS would receive the Lena Point site and would transfer its Auke Cape property to Juneau, which in turn would transfer another quarry site to SECON. Access to the site would be provided by Point Lena Loop Road and Towers Road. The facility would include approximately 88,000 gross square feet (gsf) of administrative office space and common areas, 58,000 gsf of laboratory space, and 3,800 gsf of warehouse space. The site would be built to accommodate 273 employees and visitors. The project would include an option to incorporate the University of Alaska Fairbanks School of Fisheries and Ocean Sciences in the facility if there were funding of design and construction. POSITIVE IMPACTS: The consolidation of the two facilities would improve the overall efficiency of program operations and reduce administrative costs. NEGATIVE IMPACTS: The construction of the project would adversely affect homes located along the Point Lena Loop Road. Increased traffic along the road would increase noise levels and alter the community character.

In the Pacific, leatherback populations are in severe decline and recovery actions must be given the highest riority. Primary threats to the species are incidental take in coastal and high seas fisheries, and the killing of nesting females and collecting of eggs at the nesting beaches. The United States does not have any nesting of leatherbacks in its jurisdiction in the Pacific, but has important foraging areas on the continental U.S. west coast and near the Hawaiian Islands. It is likely that stocks in U.S. water originate in Mexico and Central America, though some may originate from Southeast Asia as well. While not directly classified as a threat, the lack of information on the movement patterns and habitat needs of this entirely pelage species (leatherbacks are the only species which remains pelagic throughout its life) is severely hampering recovery efforts and must be addressed as a high priority. The recovery goal is to delist the species.

This latter classification was based on the extensive over-harvesting of olive ridleys in Mexico, which caused a serve population decline. Since the ban on the harvest of turtles in Mexico, the primary threat to the Mexican nesting population as been reduced and the population appears to be stabilizing. Downlisting to Threatened status may be feasible. The primary threats to the olive ridley appear to be indicental take in fisheries and boat collisions while in U.S. waters (or by U.S.-based fishing fleets), and the harvest of turtles and eggs on Mexican and Central American nesting beaches.

Interviewer-administered questionnaires are specialized forms of conversation, but this framework is less fitting for self-administered questionnaires; eg, self-administered questionnaires maintain the structure of conversational turn taking, but violate the sequential nature of these turns, as respondents have access to future "exchanges." Also, reading introduces additional cognitive processes that affect question answering. Cognitive tests on a series of self-administered questionnaires from the US Decennial Census are used to examine the applicability of the conversational metaphor to the self-administered questionnaire. Questionnaires completed by low-literate populations suggest that reading skills & specific familiarity with questionnaire formats & conventions are necessary for successful completion of a self-administered questionnaire. Other respondents use familiarity with administrative documents to make sense of questions; thus, prior knowledge & expectation play an important role in response. Together, these skills & prior expectations are called "forms literacy." Literacy & prior expectation have important consequences for the pretesting of questionnaires, in terms of (1) choice of respondents in cognitive testing; (2) the practice of reading aloud during cognitive interviewing, & (3) analysis of respondent errors.

Today, the US fertility rate is near or below replacement level, & the baby-boom generation is moving beyond childbearing age. Therefore, future growth in the population will occur primarily through immigration & through births to immigrants & their descendants. Census projections indicate that the proportion of children under age 18 who are white non-Hispanic will decline steadily & rapidly, from about 69% in 1990 to only 50% in 2030. Conversely, the proportion of children who are Hispanic, black, Asian, or of another nonwhite race is expected to expand from 30% to 50%. Data from the 1910, 1960, & 1990 decennial censuses are used to analyze historical changes experienced by first-, second-, & later-generation children regarding (1) parental presence in the home, (2) number of siblings in the home, (3) parental literacy & educational attainments, (4) paternal & maternal labor force participation including part- & full-time work, (5) poverty & income inequality, & (6) overcrowded housing conditions. Analyses are also conducted for first- & second-generation children of changes in their countries of origin, language, parental language, citizenship, & state of residence. Children most at risk of harmful consequences are identified, & the role of race & ethnicity in influencing resources available to children & their future prospects is evaluated.

County-level population estimates are analyzed using a spatial accounting framework to consider variations by region & county economic profile, the relative strength of increased inmigration & decreased outmigration, & the role of manufacturing trends. Among the conclusions drawn is that population deconcentration has been general & geographically well-distributed despite a temporary reversal in the 1980s. Many types of rural counties have experienced reduced outmigration & increased inmigration, due in part to people's economic ability to exercise their preference for smaller places of residence. However, only about 20% of the US population lives outside of metropolitan areas, & the rural rebound of the 1990s appears to be highly sensitive to metropolitan & global economic processes. 4 Tables, 5 Figures, 31 References.

The primary data set came from a chain of eight, three-component magnetometer stations that was operated along a north-south line in central Australia. Additional records, necessary for boundary conditions, were added to the data set. A regional spherical harmonic analysis (SHA) allowed the separation of the internal and external field contributions to the Sq variations. Mapping of the equivalent ionospheric current from the external field showed that the Sq contour focus passed near the -30 degrees geomagnetic latitude of central Australia with a 5 degrees latitude variation between winter and summer and a corresponding change from about 80 to 200 kA in strength. A special transfer function allowed the computation of an equivalent conductivity-depth profile of central Australia from the paired external and internal coefficients of the SHA. A regression line through the conductivity estimates gives a profile that starts at 0.025 S/m for a depth of 130 km, rising gradually to about 0.045 S/m at 250 km, then steepens to 0.11 S/m at 360 km and rises moderately to 0.13 S/m at 470 km near the base of the upper mantle. No data were obtained through the mantle transition zone. Computations gave 0.18 S/m in the region of 800 km depth. Previous conductivity models for the upper mantle beneath central Australia, although less specific in values, are consistent with our profile. At depths greater than 500 km, the regression profile is in agreement with the conductivity distribution beneath the Tasman Sea determined from seafloor magnetotellurics, although both measurements lack high resolution at such depths.

This method greatly reduces the computational effort required to apply MINQUE, thus making it practical to compute variance factors for some very large systems of equations. The computer implementation of the method is described and applied to the computation of variance factors for a combination of 1609 VLBI (Very Long Baseline Interferometry) observing sessions. The purpose of this test was to compute a variance factor for each of the data sets and, perhaps, to obtain more realistic variance estimates to replace those in common use for the analysis of VLBI data. It was found that the method is satisfactory for use with such large problems, and the test served to verify that the variances in current use in VLBI data adjustments are adequate.

The evaluations support the following suggestions: (a) The mean annual runoff of all models follows, at least generally, the strong climatic East-West gradient of precipitation, although most models predict too much runoff in the dry part of the basin. (b) The mean monthly storage change tends to be underestimated, even though all models capture reasonably well the seasonality of the evapotranspiration. (c) The wide range of conceptualizations used for generation of surface and subsurface runoff strongly affect runoff generation on seasonal, and shorter, time scales. Model responses to summer precipitation ranged from almost no summer runoff (one model) to the (more common) situation of persistent overprediction of summer runoff, especially in the driest part of the basin. (d) All models tended to underpredict evapotranspiration in summer and overpredict in winter. (e) Model-derived mean seasonal cycles of changes in soil moisture storage are qualitatively similar to those inferred from observations, but most models do not predict the decrease in April soil moisture storage and the increase in October that is inferred from observations.

Comparisons of simulated surface energy fluxes among models showed that the net radiation and surface temperature generally had the best agreement among the schemes. On an average (annual and monthly) basis, the estimated latent heat fluxes agreed (to within approximate estimation errors) with the latent heat fluxes derived from a radiosonde-based atmospheric budget method for slightly more than half of the schemes. The sensible heat fluxes had larger differences among the schemes than did the latent heat fluxes, and the model-simulated ground heat fluxes had large variations among the schemes. The spatial patterns of the model-computed net radiation and surface temperature were generally similar among the schemes, and appear reasonable and consistent with observations of related variables, such as surface air temperature. The spatial mean patterns of latent and sensible heat fluxes were less similar than for net radiation, and the spatial patterns of the ground heat flux vary greatly among the 16 schemes. Generally, there is less similarity among the models in the temporal (interannual) variability of surface fluxes and temperature than there is in the mean fields, even for schemes with similar mean fields.

Forcing data (precipitation, incoming radiation and surface meteorology) and land-surface characteristics (soil and vegetation parameters) were provided to each of the participating schemes. Two groups of runs are presented. (1) Calibration-validation runs, using data from six small catchments distributed across the modeling domain. These runs were designed to test the ability of the schemes to transfer information about model parameters to other catchments and to the computational grid boxes. (2) Base-runs, using data for 1979-1988, designed to evaluate the ability of the schemes to reproduce measured energy and water fluxes over multiple seasonal cycles across a climatically diverse, continental-scale basin. All schemes completed the base-runs but five schemes chose not to calibrate. Observational data (from 1980-1986) including daily river flows and monthly basin total evaporation estimated through an atmospheric budget analysis, were used to evaluate model performance. In general, the results are consistent with earlier PILPS experiments in terms of differences among models in predicted water and energy fluxes. The mean annual net radiation varied between 80 and 105 W m (super -2) (excluding one model). The mean annual Bowen ratio varied from 0.52 to 1.73 (also excluding one model) as compared to the data-estimated value of 0.92. The run-off ratios varied from a low of 0.02 to a high of 0.41, as compared to an observed value of 0.15. In general, those schemes that did not calibrate performed worse, not only on the validation catchments, but also at the scale of the entire modeling domain. This suggests that further PILPS experiments on the value of calibration need to be carried out.

This interest in Great Lakes research was evident before the turn of the century under the leadership of Prof. Jacob E. Reighard. Early research was primarily concerned with fish and fisheries. The emphasis on fisheries started to shift to basic limnological research after the 1920s when Prof. Paul S. Welch started a limnology course and wrote his book Limnology. His student, Prof. David C. Chandler, returned to the University in 1953 to chair the Council of the Great Lakes Research Institute, and subsequently became the Director of the Great Lakes Research Division in 1960. The emphasis was and has been on basic and applied research involving a broad spectrum of disciplines. The published contributions include biology, chemistry, geology, meteorology, paleolimnology, physical limnology, pollution, radiolimnology, and integrated studies. Among the University's many contributions to furthering Great Lakes research was the origination of the Conferences on Great Lakes Research, started in 1953. Publications of the Proceedings of these conferences provided a valuable reference to research in the 1950s and 1960s. These conferences led to the formation of the International Association for Great Lakes Research and subsequently the Journal of Great Lakes Research. The University acquired several research vessels. The earliest large vessel acquired was the Inland Seas (1960) which was replaced by the Laurentian in 1974. A research submersible was brought into Lake Michigan for evaluation by the Great Lakes Research Division in 1966. At about this time Michigan Sea Grant Program was started in 1969 and the Coastal Zone Laboratory in the 1970s. More recently the Cooperative Institute for Limnology and Ecosystem Research was created in 1989 as a partnership among the University, Michigan State University, and the Great Lakes Environmental Research Laboratory of the National Oceanic and Atmospheric Administration. Much of the Great Lakes research activity at the University was realigned into several colleges and schools in the late 1980s. Great Lakes research at the University has passed through a number of reorganizations, and now exists as the Aquatic Research Programs of the University of Michigan Biological Station.

AN - 52513005; 1999-016008 AB - This study investigated the composition of particulate matter in a series of sediment traps set in the offshore waters of southeastern Lake Michigan. April to October 1982. Of particular interest was the role of zooplankton fecal pellets in rapidly transporting matter from the euphotic zone to lake sediments. Particulate flux was examined microscopically. Dry weight and settling velocities were then estimated based on literature conversion factors and predictive equations. There was an excellent correspondence between estimated flux and direct measurements of flux. Flux was dominated by biological particles of autochthonous origin: fecal matter, fecal pellets, organic aggregates, phytoplankton, and zooplankton exoskeletons. Particles were small with slow (generally <10 m/day) settling velocities. Flux varied seasonally, being highest in spring and autumn, during vertical mixing, and lowest in mid-summer, during strong thermal stratification. High trapping rates during isothermal conditions previously have been associated with resuspension. However, free minerals were a relatively small component of flux. This suggests that isothermal events are associated with the resuspension of previously-settled mineral particles with these particles and slowly-settling biological particles being kept in suspension until the onset of thermal stratification. Because zooplankton fecal pellets and fecal matter are subject to significant degradation and reingestion during the days to weeks that are required for them to reach the lake floor, these egestion products may play a greater role in the recycling of matter in the water column than in the direct transport of matter to the sediments. During summer, when the abundant zooplankton population is food-limited and cladocerans, which produce diffuse egestion products are numerous, relatively little of materials produced in the epilimnion settles immediately to the lake floor.

Independent evaluations of the Cariaco Basin calendar and (super 14) C chronologies were based on the agreement of varve ages with the GISP2 ice core layer chronology for similar high-resolution paleoclimate records, in addition to (super 14) C age agreement with terrestrial (super 14) C dates, even during large climatic changes. These assessments indicate that the Cariaco Basin (super 14) C reservoir age remained stable throughout the Younger Dryas and late Allerod climatic events and that the varve and (super 14) C chronologies provide an accurate alternative to existing calibrations based on coral U/Th dates. The Cariaco Basin calibration generally agrees with coral-derived calibrations but is more continuous and resolves century-scale details of (super 14) C change not seen in the coral records. (super 14) C plateaus can be identified at 9.6, 11.4, and 11.7 (super 14) C ka BP, in addition to a large, sloping "plateau" during the Younger Dryas ( approximately 10 to 11 (super 14) C ka BP). Accounting for features such as these is crucial to determining the relative timing and rates of change during abrupt global climate changes of the last deglaciation.

The work was stimulated, in part, by an atmospheric particle "sample of opportunity" collected at Summit, Greenland in August 1994, that bore the (super 14) C imprint of biomass burning. During the summer field seasons of 1995 and 1996, we collected air filter, surface snow and snowpit samples to investigate chemical and isotopic evidence of combustion particles that had been transported from distant fires. Among the chemical tracers employed for source identification are organic acids, potassium and ammonium ions, and elemental and organic components of carbonaceous particles. Ion chromatography, performed by members of the Climate Change Research Center (University of New Hampshire), has been especially valuable in indicating periods at Summit that were likely to have been affected by the long range transport of biomass burning aerosol. Univariate and multivariate patterns of the ion concentrations in the snow and ice pinpointed surface and snowpit samples for the direct analysis of particulate (soot) carbon and carbon isotopes. The research at NIST is focusing on graphitic and polycyclic aromatic carbon, which serve as almost certain indicators of fire, and measurements of carbon isotopes, especially (super 14) C, to distinguish fossil and biomass combustion sources. Complementing the chemical and isotopic record, are direct "visual" (satellite imagery) records and less direct backtrajectory records, to indicate geographic source regions and transport paths. In this paper we illustrate the unique way in which the synthesis of the chemical, isotopic, satellite and trajectory data enhances our ability to develop the recent history of the formation and transport of soot deposited in the polar snow and ice.

Furthermore, we present first results obtained at the Vienna Environmental Research Accelerator (VERA) from (super 14) C measurements of a snow sample from Gaithersburg, Maryland, USA, prepared at the National Institute of Standards and Technology (NIST).

On the practical side, the answer to this question impacts the best achievable precision in well-controlled counting experiments. There have been some noteworthy experimental tests of the Poisson assumption, using systems carefully designed for the analysis of individual pulses from stable radioactive sources; thus far, experiment supports theory. For low-level counting, the nature of the background distribution can be of profound practical importance, especially for very long counting experiments where validation by an adequate number of full replicates may be impracticable. One is tempted in such cases to assume that the variance is equal to the mean, in order to estimate the measurement uncertainty. Background radiation, however, has multiple components, only some of which are governed by the laws of radioactive decay. A specially designed low-level gas counting system at NIST for interactive, retrospective individual pulse shape and time series analysis makes possible the investigation of the empirical distribution function of the background radiation, in a manner similar to the previous empirical distribution studies of radioactive decay. Benefits of individual pulse analysis are that there is no information loss due to averaging and that two independent tests of the Poisson hypothesis can be performed using data from a single, extended measurement period without the need for replication; namely, tests of the distribution of arrival times, expected to be uniform, and the distribution of inter-arrival times, expected to be exponential. For low-level counting the second test has a very interesting and very informative complement: the distribution of coincidence-anticoincidence inter-arrival times. Key outcomes from the study were that: 1) nonstationarity in the mean background rate over extended periods of time could be compensated by an on-line paired counter technique, which is far preferable to the questionable practice of using an "error-multiplier" that presumes the wandering (nonstationary) background to be random; and 2) individual empirical pulse distributions differed from the ideal GM and Poisson processes by exhibiting giant pulses, a continuum of small pulses, afterpulses, and in certain circumstances bursts of pulses and transient relaxation processes. The afterpulses constituted ca. 8% of the anti-coincidence background events, yet they escaped detection by the conventional distributional tests.

Some of these particles result from combustion processes and have undergone long-range transport to arrive in the Arctic. Recent research has focused on the separation of particulate matter from ice and snow, as well as the subsequent analysis of the separated particles for (super 14) C with accelerator mass spectrometry (AMS) and for individual particle compositions with laser microprobe mass analysis (LAMMA). The very low particulate concentrations in Arctic samples make these measurements a challenge. The first task is to separate the particles from the ice core. Two major options exist to accomplish this separation. One option is to melt the ice and then filter the meltwater. A second option is to sublimate the ice core directly, depositing the particles onto a surface. This work demonstrates that greater control is obtained through sublimation. A suite of analytical methods has been used for the measurement of the carbon in snow and ice. Total carbon was analyzed with a carbon/nitrogen/hydrogen (CHN) analyzer. AMS was used for the determination of carbon isotopes. Since source identification of the carbonaceous particles is of primary importance here, the use of LAMMA was incorporated to link individual particle molecular-structural patterns to the same group of particles that were measured by the other techniques. Prior to this study, neither AMS nor LAMMA had been applied to particles contained in snow. This paper discusses the development and limitations of the methodology required to make these measurements.

During 1994 and 1995 we sampled planktonic larval distributions and hydrography both south and north of Point Reyes during upwelling to test whether high concentrations of crab and rockfish larvae were concentrated in the source of the relaxation flow to the south of Point Reyes. An upwelling plume off Point Reyes and an "upwelling shadow", indicated by warmer, less saline water in the northern Gulf, were evident in both years, as were frontal regions that marked the boundaries between water types of three different types: (1) newly upwelled, (2) oceanic, and (3) San Francisco Bay outflow. In addition, there was a fourth type, termed Gulf water, that was a mixture of these three types. Concentrations of larvae of cancrid, pinnotherid, and "coastal" crabs and rockfishes were high south of Point Reyes but were low or absent in the newly upwelled water north of the point. Within the upwelling shadow, these meroplankton taxa were associated with different water masses. Several intertidal crab species and early-stage cancrid crabs were concentrated in San Francisco Bay outflow water, and coastal Gulf water late-stage cancrid crabs, early- and late-stage pinnotherid crabs, and rockfishes were concentrated at the frontal region between newly upwelled and Gulf water. Of the taxa examined, only rockfishes were found offshore in oceanic water. The high concentrations of meroplankton observed suggest that the Gulf of the Farallones is an important area for larvae that settle into coastal populations in the Gulf and to the north via poleward transport during upwelling relaxation.

C-band radar backscatter signatures of various ice types and open water were measured from U.S. Coast Guard Ice Breaker vessels together with ground truth data. Polarimetric backscatter data were obtained at incident angles up to 60 degrees for all polarizations. Backscatter signatures of 20 ice types/conditions were collected along the Coast Guard ship tracks in February and March 1997. The backscatter data set with in-situ ice characteristic parameter measurements are to be used in the development of the ice mapping algorithms using satellite SAR data over the Great Lakes. The results at C-band frequency for multiple incident angles and multiple polarizations are applicable to the current ERS and RADARSAT Synthetic Aperture Radars (SAR) and the future ENVISAT SAR.

Over land the SSM/I measurements at 19, 37 and 85 GHz are used to routinely identify precipitation, snow cover and the surface wetness resulting from rainfall and snow melt. In the case of snow, the measurements vary as function of snow water equivalent, grain size and snow density. Ice crusts at the surface and within the snow can also affect the measurements. As such, the SSM/I measurements depend on the internal properties of snow as well as the snow extent. Studies based on radiative transfer simulations are used to examine the effects of the various snow parameters on the microwave measurements. Temporal variations of the SSM/I measurements are compared with snow data over the former Soviet Union. It is evident that both temporal and spectral information is needed to identify changes in the physical characteristics of snow.

Nearly all of the nation's coastal states have management programs that seek to enhance the wise use of natural resources in the dynamic, yet vulnerable, ecosystems that constitute our coasts. The National Oceanic and Atmospheric Administration Coastal Services Center works with local partners to compile hazards data that specifically address coastal management issues. The goal of these projects is to build upon methodologies being developed nationally for local hazards risk and vulnerability assessments. These projects utilize the newest spatial data technologies, including hurricane storm surge models, LIDAR beach mapping, and products derived from remotely sensed imagery. These CD-ROM products provide different user levels with multiple ways to access the data: a web-browser for viewing static maps, policy descriptions, and hazards analysis; ArcExplorer (super R) for users without geographic information system software; and an ArcView (super R) project file. A CD-ROM has been completed in a cooperative project with the State of Alabama Coastal Zone Program and the South Alabama Regional Planning Commission.

At five other sites, back-scatter anomalies were less distinct, and at the remaining sites, anomalies were absent. These are the first documented hydrothermal sites along this intermediate-rate spreading center and are among the very few yet discovered in the Indian Ocean basin. Some profiles exhibit complex back-scatter anomalies suggestive of multiple sources of seafloor discharge. At one site, near-bottom temperature anomalies of approximately 0.1 degrees C and the recovery of a vent-specific barnacle provide the first precise seafloor location of active venting in the deep Indian Ocean. Although this study is only reconnaissance in nature, venting along this portion of the SEIR appears to be significantly less than predicted by global correlations of plume incidence as a function of spreading rate. Nevertheless, these sites may be important as biological connections between distinct faunal assemblages of Atlantic and Pacific vent fields. Copyright 1998 by the American Geophysical Union.

These are the first ridge-flank hydrothermal springs discovered on crust older than 1 Ma. The springs are venting altered seawater at 25.0 degrees C along a fault near the summit of Baby Bare outcrop, a high point along a ridge-axis-parallel basement ridge that is otherwise buried by turbidite sediment. Baby Bare is a small volcano that probably erupted off-axis ca. 1.7 Ma; it is thermally extinct, but acts as a high-permeability conduit for venting of basement fluids. The springs have been sampled from the manned submersible Alvin. Compared with the ambient ocean bottom water, they are heavily depleted in Mg, alkalinity, CO (sub 2) , sulfate, K, Li, U, O (sub 2) , nitrate, and phosphate, and enriched in Ca, chlorinity, ammonia, Fe, Mn, H (sub 2) S, H (sub 2) , CH (sub 4) , (super 222) Rn, and (super 226) Ra. The springs appear to support a community of thysirid clams. Although we saw no obvious bacterial mats, the surficial sediments contain the highest biomass concentrations ever measured in the deep sea, based on their phospholipid phosphate content. Areal integration of Alvin heat-flow and pore-water velocity data yields flux estimates of 4-13 L/s and 2-3 MW for the total (diffuse and focused) hydrothermal output from Baby Bare, comparable to that from a black smoker vent on the ridge axis. Warm springs such as those on Baby Bare may be important for global geochemical fluxes.

A Report of the Turtle Expert Working Group AN - 19464910; 8016544 AB - At the behest of NMFS, the SEFSC established the Turtle Expert Working Group (TEWG) in February 1995. The charge of the TWEG was first identified in the Endangered Species Act-Section 7 Consultation Biological Opinion for Shrimp Trawling in the southeastern United States under the Sea Turtle Conservation Regulations issued in November 1995. Specifically, NMFS was required to 'select a team of population biologists, sea turtle scientists, and life history specialists to compile and examine formation on the status of sea turtle species. The team should attempt to identify (1) the maximum number of individual sea turtles of each species that can be taken incidentally to commercial fishing activities without preventing the recovery of the species, (2) the maximum number of individuals that can be taken incidently to commercial fishing activities without jeopardizing the continued existence of any listed sea turtle species, and (3) the number of stranded sea turtles occurring in statistical zone that indicate incidental takes are occurring at levels beyond those authorized.' Since the first meeting in June, 1995, there have been 3 subsequent formal meetings which have culminated in the two stock level reports that constitute this publication. There is embodied in this publication a status report for the loggerhead turtle, Caretta caretta, within the southeast U.S. and the Kemp's ridely, Lepidochelys kempii, which is found in both Mexican and U.S. waters. This effort which represents the beginning of an evaluation of the status and condition of these stocks is considered preliminary and exploratory. The authors consider these efforts a work in progress. The TEWG is continuing in it's initial endeavors to develop methods to proceed with stock assessments for turtles and the authors are optimistic that this will be realized. it is the TEWG's desire that the results published in this report be interpreted with caution and within the bounds of the assumptions both with the data and with the methodologies applies. The authors wish to note that the exploratory modelling for the Kemp's ridley was completed only in the context of attempting to understand the life history of this species and to extract population level parameters which duplicate empirical data and numerical trends in abundance.

Part 1: Background and Information Needs AN - 17966197; 5905971 AB - A two day workshop was convened on February 2-3, 1998 in Charleston, SC with 20 invited experts in various areas of sea turtle research. The goal of this workshop was to review current information on sea turtles with respect to health and identify data gaps. The use of a suite of health assessment indicators will provide insight on the health status of sea turtle populations. Since the relationship of health factors of sea turtles is limited, a second workshop was planned. Using a tiered approach, the first workshop the authors identified and reviewed the available, pertinent baseline information and data gaps. The second workshop will focus on developing the framework for the research plan. The workshops will address the use of integrated set of health parameters; specific objectives are: Identify reliable indicators of health in sea turtles; assess advantages and disadvantages; determine new indicators/biomarkers which may be useful; Review existing sea turtle field sampling projects; Identify field projects suitable for inclusion for health assessment sampling; Identify data gaps, particularly environmental characterization; Identify new health assessment sampling sites, including reference site(s); Develop integrated five-year reserach plan, with focus on health assessment and environmental characterization.

Twenty-seven reports were prepared during this period. Histology reports from the Armed Forces Institute of Pathology (AFIP), Washington, D.C., were received for 21 of these animals. Causes of death were suggested by the AFIP through histological examination and gross necropsy findings, for 11 of the 21 animals (52.4%). Preparation of necropsy reports and collection and packaging of tissues by consistent protocols proved to increase the chances of determining the causes of death through histological examination by the AFIP.

Radioecological situations in the coastal zone and in the open area of the south-eastern Baltic were observed. The objective analysis method was used to define the radionuclide VA field structure. The measured and calculated results of VA field comparison in the south-eastern was satisfactory. According to the nuclear hydrophysical model the imitated situation of a 'passive' admixture spreading calculation in the south-eastern Baltic was carried out. In the case of a 'pollution II source concentration 106 times exceeding the 'natural' background at the western wind velocity of 10 m/s, the whole coastal area of Lithuania would be contaminated in three days.

N1 - Last updated - 2015-03-24 ER - TY - JOUR T1 - Effect of the Niagara River Chippawa Grass Island Pool on Water Levels of Lakes Erie, St. Clair, and Michigan-Huron AN - 17357162; 4511083 AB - Because of renewed riparian interest stemming from the high Lake Erie water levels of the mid-1980s and mid-1990s, and the need for a concise summary of previous studies, a review and a new assessment of the impact of the Niagara River's Chippawa Grass Island Pool on Lake Erie water levels was undertaken. Numerous field and modeling studies dating from 1953 through 1988 provide different assessments of the impacts. The impacts reported by the studies range from "no measureable effect" to a 2 to 5 cm Lake Erie water level decrease. The different results are due to different methods and data, and the fact that the impacts are not directly measureable. A new Great Lakes routing model that more accurately reflects the upper Niagara River hydraulics by explicitly considering the management directive of the Chippawa Grass Island Pool is used to estimate the impacts of deviating from the present directive. The long-term impact of a 0.30 m increase or decrease from the current directive's long-term mean pool level on Lakes Erie, St. Clair, and Michigan-Huron levels is 5 cm, 4 cm, and 2 cm and -4 cm, -3 cm, and -2 cm, respectively. The lakes are minimally responsive to short-term changes in pool levels, with 50% of the Lake Erie impact achieved at about 6 months, and full impact achieved at about 2 years. The minimal lake response, the time lag to full impact, and the local problems resulting from directive deviations, make this a less favorable emergency response measure during periods of extreme lake levels than other alternatives.

This work reviews the recent findings of factors influencing the organism with particular focus on interpreting the potential for contaminant stress, with an emphasis on organic contaminants, and the benthic pelagic link for contaminant food web transfer. The review includes examination of the environmental features that limit the distribution and population density. The physiology of Diporeia spp., including energy storage, respiration, and nutrient elimination, are discussed. The toxicokinetics from both aqueous and sediment exposures are reviewed, as well as both the environmental factors that influence the kinetics and the limitations to our knowledge. The interactions of the physiology and toxicokinetics are presented for interpretation of toxic responses and the sensitivity of the organism to selected contaminants. Finally, this review suggests areas where increased information is needed to improve our understanding of Diporeia toxicokinetics and toxicity in the Great Lakes environment.

Penn Cove, which receives nutrients from the nearby Skagit River and abundant sunshine during summer months due to its location in the rain shadow of the Olympic Mountains, is the home of a commercial mussel farm which supplies shellfish to many coastal areas of the USA. Levels of domoic acid in mussels increased to 3 ppm on 6 and 10 July, corresponding to the observation of a brown algal bloom in Penn Cove. Four species of Pseudo-nitzschia (P. pungens, P. multiseries, P. australis, and P. pseudodelicatissima) were present in our samples from the cove, corresponding to levels of domoic acid in seawater ranging from 0.1-0.8 mu g l super(-1) as measured by a receptor binding assay. The highest Pseudo-nitzschia concentration during the time of our sampling was 13 million cells per liter on 28 July. The bloom of Pseudo-nitzschia occurred after a period of strong discharge from the Skagit River and rain accompanied by elevated south and southeasterly winds. Stratification of the cove, providing optimal bloom conditions, was facilitated by weak winds, sunshine, and a freshwater lens at the mouth of the cove. The position of the Pseudo-nitzschia bloom was influenced by buoyancy fronts caused by exchange of water within the cove with that of Saratoga Passage.

These and future observations aid in the development of a model for prediction of toxic bloom events in the shallow embayments of Puget Sound.

A growing awareness that the quality of the coastal ecosystems is being adversely impacted by multiple driving forces has accelerated efforts by scientists and program managers to assess, monitor, and mitigate coastal stressors from an ecosystem perspective. The Intergovernmental Oceanographic Commission (IOC) of the United Nations Educational, Scientific, and Cultural Organization (UNESCO) is encouraging coastal nations to establish national programs for assessing and monitoring coastal ecosystems so as to enhance the ability of national and regional management organizations to develop and implement effective remedial programs for improving the quality of degraded ecosystems. This encouragement follows from the significant milestone achieved in June, 1992, with the adoption by a majority of coastal countries of follow-on actions to the UNCED declarations on the ocean for the nations of the globe to: (1) prevent, reduce, and control degradation of the marine environment so as to maintain and improve its life-support and productive capacities; (2) develop and increase the potential of marine living resources to meet human nutritional needs, as well as social, economic, and development goals; and (3) promote the integrated management and sustainable development of coastal areas and the marine environment.

We consider structures or elements whose design is governed by wind loads and for which wind directionality effects are not significant. We present estimates according to which ASCE 7-95 Standard provisions for wind loads inducing the design strength result in (1) safety levels that are considerably lower for hurricane-prone than for extratropical storm regions, and (2) estimates of mean recurrence intervals of hurricane wind loads inducing the design strength of about 500 y if epistemic uncertainties are neglected, and significantly lower than 500 years otherwise.

The decline resulted largely from over harvest and direct and indirect losses due to environmental modifications, particularly dam construction. Pool-and-weir fish ladders, with submerged orifices, now successfully pass a large percentage of adult fish at each mainstem dam. Some adult passage delays still exist due to an inability of fish to find entrances to fishways, poor site locations of ladder entrances, inadequate or confusing water velocities that fish reject, and/or poor velocity transitions between fishways or channels into the actual ladders. At all facilities, some fish reject the fishways so that cumulative losses also affect overall stock spawning success. Passage facilities to divert downstream juvenile migrants away from irrigation canals and turbines have been less successful even though US$100s of millions have been spent in the past 20 years on constructing and maintaining louvres, drum screens, bar screens, travelling screens and surface collection devices. Lack of detailed understanding of juvenile fish behaviour related to flow appears to be one of the largest impediments to the development of effective fishways. Further, a lack of periodic maintenance of fishways and screens may decrease their effectiveness.

I will explain what these changes were, what they mean, and how they are being implemented in New England, to provide some context for the discussion about the effects of fishing gear on habitat. The Magnuson Act requirements for habitat information before the 1996 amendments were fairly general. The Act required that each fishery management plan (FMP) must "include readily available information regarding the significance of habitat to the fishery and assessment as to the effects which changes to that habitat may have upon the fishery." Fishery management plans needed to include information about habitat and potential threats, but the law called no attention to important habitat areas and did not require any specific measures to protect habitat.

These samples were analyzed for tissue levels of 16 chlorinated organic compounds, mostly pesticides, as well as for lipid levels. Aldrin, endrin, and lindane were found above detection levels at less than one-half of the sites, primarily at sites in Lake Michigan. Mirex was detected at nine sites mostly in Lake Ontario and the Niagara River, but also near Detroit and in Saginaw Bay. Heptachlor was detected at only two sites, both in Lake Erie. Cis-chlordane, dieldrin, hexachlorobenzene, heptachlor, trans-nonachlor, and total DDTs were detected at all or almost all of the sites. Except for hexachlorobenzene, which was highest near Buffalo, these chemicals were found at higher concentrations in Lake Michigan, especially near Milwaukee, than in the other areas studied. A comparison of the concentrations of chlorinated organic compounds to the levels of lipids showed that differences in dreissenid lipid levels among sites were not the major cause of the observed differences in concentrations in the chlorinated organic compounds. At most sampling locations, the category total DDTs was composed primarily of the DDT breakdown products DDD and especially DDE. However, a substantial percentage of the total DDTs detected at sites in eastern Lake Erie and western Lake Ontario was composed of the parent DDT compounds, suggesting the presence of a relatively recent input of this compound in this area. Comparison of the concentrations of chlorinated organic compounds measured in Great Lakes dreissenids with concentrations of these compounds in marine mussels and oysters found generally similar levels for most of the compounds. Exceptions to this were hexachlorobenzene and mirex which had mean concentrations more than 5 times greater in mussels from the Great Lakes than from marine locations and lindane which had concentrations in mussels from the Great Lakes less than one-tenth of those from marine mussels.

All components of the planktonic food-web were collected from the same water sample (with the exception of crustaceans), counted microscopically, converted to carbon units, and averaged over the euphotic zone. Due to phosphorus load reductions and the impact of non-indigenous mussels in the lower lakes, physical/chemical characteristics of the lower lakes are becoming similar to those in the upper lakes. Spring total phosphorus and euphotic zone depth were relatively similar among all the stations (except western Lake Erie), ranging from 3 to 7 mu g/L and 21 to 26 m, respectively. During the summer, total phosphorus concentrations were more variable, but ranged between 4 to 10 mu g/L at all stations except western Lake Erie. Planktonic biomass was correlated with total phosphorus concentration. Within a season, the structure of the planktonic food-web was remarkably similar among all stations across all the lakes. Of the seventeen food-web structure parameters examined, only two exhibited significant differences among stations during the spring isothermal period; only four parameters exhibited significant differences among stations during the summer.

A mortality limit (termed the Potential Biological Removal, PBR, under the U.S. Marine Mammal Protection Act) was calculated as the product of a minimum population estimate (N sub(MIN)), one-half of the maximum net productivity rate (R sub(MAX)), and a recovery factor (F sub(R)). Mortality limits were evaluated based on whether at least 95% of the simulated populations met two criteria: (1) that populations starting at the maximum net productivity level (MNPL) stayed there or above after 20 yr, and (2) that populations starting at 30% of carrying-capacity (K) recovered to at least MNPL after 100 yr. Simulations of populations that experienced mortality equal to the PBR indicated that using approximately the 20th percentile (the lower 60% log-normal confidence limit) of the abundance estimate for N sub(MIN) met the criteria for both cetaceans (assuming R sub(MAX) = 0.04) and pinnipeds (assuming R sub(MAX) = 0.12). Additional simulations that included plausible levels of bias in the available information indicated that using a value of 0.5 for F sub(R) would meet both criteria during these "bias trials." It is concluded that any marine mammal population with an estimate of human-caused mortality that is greater than its PBR has a level of mortality that could lead to the depletion of the population. The simulation methods were also used to show how mortality limits could be calculated to meet conservation goals other than the U.S. goal of maintaining populations above MNPL.

Currently, northern elephant seals breed on thirteen islands and four mainland sites from Isla Cedros in Baja California Sur, Mexico, to Cape Arago, Oregon, USA. Le Boeuf et al. (1996) reported observations of stray juveniles as far away as Amaknak Island in the Aleutian Islands, Midway Island and Hokkaido, Japan. There are no historical records to indicate whether elephant seals occurred in the Gulf of California, prior to 1979, when the first known observation was made.

The author studied the first step in the predation sequence, reaction to prey, for different zooplankton taxa by lake herring. Reactive distance was significantly shorter for smaller zooplankton taxa (p < 0.0001). Reactive volume was calculated from measured distances and angles of elevation and bearing. This volume augments the reactive distance data and showed a three dimensional geometry, roughly analogous to a deflated basketball, that is amenable to a cruising style of planktivory. Reactive volume is dynamic with respect to variations in prey size (p < 0.001). Reactive volume is a refined measure of a 'reaction' by fish to a prey item than are simple, linear distances or other, assumed shapes. Thus, for a cruising planktivore, three dimensions need to be considered.

Based on biometric changes that are projected to occur, it appears that early control of a non-indigenous fish species, specifically ruffe (Gymnocephalus cernuus), can result in significant investment returns. By instituting a ruffe control program, benefits to the public will exceed costs by 44 to 1 over the next five decades. Under a moderate case projection of benefits this will yield an estimated net public savings of $513 million for the United States. Since sportfishing values are much greater than commercial fishing values, anglers will benefit the most from this program.

The management community, academic researchers, and others, spurred on by a growing body of concerned ocean resource users, have begun to grapple with the notion of ocean governance based on the principles of ecosystem management. Marine protected areas (MPAs) are one key element in this growing era of bigger thinking and in the context of national ocean governance discussions. The inclusion of marine protected areas initiatives in the ocean governance discussions is a positive step toward integrating ecosystem principles within this governance structure, and a number of valuable lessons can be gleaned from taking a look at some of these efforts. This paper focuses on one such program, NOAA's National Marine Sanctuary Program (NMSP), and provides some insights into its evolution and innovative efforts to foster ecosystem management in and around these coastal and ocean areas. This discussion will profile new ideas being formulated by the NMSP which address how MPAs such as these sanctuaries can provide opportunities for catalyzing broader ecosystem management initiatives and how they can serve as laboratories for developing innovative and alternative ocean governance mechanisms. Finally, the paper will examine the critical role of forging effective partnerships to make this essential coordination and collaboration a reality for successful ocean governance.

This "best-available" information involves analysis from a number of experts. The decision-maker must compile these discrete pieces of information to make decisions on protection strategies and priorities. In response situations, it can sometimes be obvious when less-than-optimum decisions have been made, In planning or drill situations, the evaluation of these decisions can be very difficult. This paper proposes a quantitative approach to integrate this information into a "game" that can be played, in a planning phase, to examine alternate scenarios. Game theory is used to design the "game", and linear programming is used to quantify and optimize the results.

The most widely used organizing tool for dealing with natural and environmental resource choices is benefit-cost analysis, which offers a convenient way to carefully identify and array, quantitatively if possible, the major costs, benefits, and consequences of a proposed policy or regulation. However, a major shortfall of benefit-cost analysis has been the difficulty of quantifying both benefits and costs of actions that impact environmental assets not normally or regularly bought and sold in markets. Economists and other social scientists have put a great deal of effort into addressing this shortcoming by developing techniques to quantify these non-market benefits. To make that link, NOAA has undertaken a series of Regional Environmental Valuation Workshops to introduce and illustrate concepts of environmental valuation to state and local coastal planners and managers, fishery managers, and those concerned with the broad range of coastal sustainability issues.

The most widely used refrigerants are among them. Chemical and equipment manufacturers mounted aggressive research and development programs to introduce alternative and transition refrigerants, associated lubricants and desiccants, and redesigned equipment. The already difficult criteria became even more complex, with subsequent linkage of chemical emissions from human activities to global climate change. The very successful response to protect the ozone layer has led some regulators and users to assume that ideal substitutes will be found. Such chemicals should be free of all environmental and safety concerns, be chemically and thermally stable, and perform efficiently. The analyses presented in this paper demonstrate that the outlook for discovery or synthesis of ideal refrigerants is extremely unlikely. Trade-offs among desired objectives, therefore, are necessary to achieve balanced solutions. The paper also shows that fragmented regulation of the chemicals involved, to address individual issues, jeopardizes the prospect of solving subsequently addressed problems. The paper reviews the history of refrigerants, their roles in ozone depletion and global climate change, and necessary trade-offs in refrigerant selections.

Halon emissions persist because of a lack of suitable substitutes for critical uses as fire extinguishants. As of January 1, 1997, halons H-1301 (CBrF sub(3)), H-1211 (CBrClF sub(2)), and H-2402 (CBr sub(2)F sub(4)) were present in the troposphere at 2.3 plus or minus 0.1, 3.5 plus or minus 0.1, and 0.45 plus or minus 0.03 pmol mol super(-1). During 1995-1996 the tropospheric mole fraction of H-1301 increased at 0.044 plus or minus 0.011 pmol mol super(-1) yr super(-1), while that for H-1211 grew at 0.16 plus or minus 0.016 pmol mol super(-1) yr super(-1). These increases are significant and of concern because of the efficiency of bromine in depleting stratospheric ozone and because of the long atmospheric lifetimes of these gases. Given the current atmospheric record and the reported amount of halon produced before the ban on production, emission of H-1301 at the 1995-1996 rate could continue for another 40 years, but H-1211 would be depleted in 8-12 years. Exemptions to the ban on production may extend these periods. Tropospheric H-2402 is increasing at 9 plus or minus 1 fmol mol super(-1) yr super(-1), but historical data on its production and use are lacking. JF - Journal of Geophysical Research. D.

AN - 16292071; 4280832 AB - Releases of hatchery-reared anadromous salmon into the North Pacific Ocean are currently estimated between 5 and 6 billion juveniles per year. Wild spawning salmon may produce an additional 4 to 5 times this number of juveniles. With as many as 25 billion juvenile Pacific salmon (Oncorhynchus spp.) annually entering the ocean and currently producing over 1.0 million mt of returning adults, salmon survival and production in the North Pacific is currently at historically high levels in spite of depressed runs and endangered stocks in some regions. Biological changes in size and age at maturity of some stocks have raised questions on the density effects of high abundance, and on the long-term well being and health of salmon stocks. Changes in size and age notwithstanding, favorable ocean conditions for survival and growth, even growth at reduced levels, have produced historic numbers and biomass of salmon suggesting the evidence for limitations in the carrying capacity for these fishes in inconclusive. Important studies are underway in several countries to better understand the effects of hatchery-wild stock interactions on the spawning grounds but little attention has been directed toward this issue in the ocean. New mass marking and identification technologies for both hatchery and wild fish provide mechanisms for investigating the interactions of salmon in the open ocean. Given biological concerns about ocean carrying capacity and socio-economic issues associated with record runs, should NPAFC member countries consider cooperative quotas to limit production of salmon around the North Pacific Rim?.

Chum salmon spawners returning to Fish Creek, southeastern Alaska, were sampled yearly from 1972 through 1996. Spawners retuning to the Quilcene National Fish Hatchery in Hood Canal, Washington, were sampled yearly from 1973 through 1996. Size at maturity of both populations declined significantly from about 1980 to the mid-1990s. Age at maturity increased during this time. These changes were associated with a major ocean climate regime shift in the North Pacific Ocean that occurred in 1976-77. Population abundance of chum salmon increased greatly after the regime shift, especially in Asia. Similar changes in size and age at maturity occurred in Asian chum salmon; because the range of North American and Asian chum salmon overlaps on the high seas, these changes are discussed in relation to possible density-dependent population factors. Since the mid-1990s, size at maturity and population abundance have increased, possibly indicating another climate change in the North Pacific Ocean.

After 3 h immersion in 2.5 ug Aroclor 1260 per g females decreased from 41.9 per cent in controls to 31.6-36.1 per cent. Abnormal gonads were observed in 18.2 per cent compared to 2.7 per cent. Inconsistent or extremely limited development of oocytes characterized the abnormalities. Fish near point sources of PCB (such as hazardous waste sites) can accumulate in excess of 10 ug per g. This preliminary study indicated that these levels cause abnormalities and raised new concerns about many sites where PCB are present in sediment in high concentrations.

Culture experiments in metal ion-buffered media revealed that toxicity, nutrition and the accumulation of cellular metals was governed by complex competitive interactions among the metals. High levels of ionic copper(II) and zinc(II) inhibited cellular manganese uptake, and high copper(II) inhibited zinc uptake rates. There was an association between these effects and growth rate inhibition at combined conditions of high zinc(II) and low manganese(II) and at high copper(II) and low zinc(II). Zinc inhibited uptake of manganese by competitively binding to a high affinity manganese uptake system. Cellular zinc concentrations increased as external manganese(II) was decreased. The uptake of zinc also involved a high-affinity zinc system which was induced in the presence of low zinc(II) and a separate low-affinity system. Zinc uptake by the high-affinity system was inhibited in the presence of high copper(II) concentrations.
