the shuli envtror.ment . For environmental impact assessment it is insuifictent to know only the orga%isms or chemical constituents present :-nd their spatial and temporal distribution . r;n understanding of controlling mechanisms or processes Is imperative before causality of future change can be determined with any degree of certainty . During the initial sampling year (October 1975 through September 1976, C,:lntract N o . 0R55U-CT5-42) specific goals of the Middle Atlantic chemical and biological Lenchmark studies were as follows : . summarization oi shelf hydrographic and meteoroingical characteris^iscs such as temperature, salinity, dissolved ,,,vgen, and micronutrients during the four sampling seasons with particular emphscis on frontal systems and water mass identificat :~on ; 2 . characterizatio .l of the water column in terms of zooplankton, neustou, bacteria, particulate trace metals, and dissolved and particulate hydrocarbons as related to each otF.er and temporal (seasonal and/or diurnal), spatial (geographic), and hydrographic variability as determined during the study ; ~ . characterization of the dominant infauna and epifauna in the macro- and mega- faunal ranges, foraminifera, and bacteria along with aediment characteristics such as grain size, organic carbon and nitrogen, sediment hydrocarbons, and sediment trace metals in relation to temporal, spatial, and hydrographic variability as determined during the sample year ; 4 . description of the histopathology of selected epiFannal and infaunal species and discussion of histopatholcgic_~1 conditions in relation to hydrocarbon and trdce metal concentrations in the se]Pcteu species ; . discussion of temporal and spatial hydrocarbon degradation potential of microbial populations in surf .ciai witer and sediments and determination of the effect of hydrocarboa products on this potential and the mineralization of chitin and cellulose, the normal substrates for microbial populations ; and 6 . (:xtension of the Virginian Sea Wave Climate Model for the region from Cape Hatteras, North Carolina, to Long Island, New York . Preliminary findings based cn the first year of study (1975-1976) were documented in a Final Report (V .I .M .S . 1977) and :an be summarized as follows . 1 . The waters of the Middle Atlantic Bighc were characterized by two vertical frontal zones dividing three water mass 3
