The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder easternberings00hood Year: 1981 Perspective i Shelf Environmental Assessment Program, funded by the Bureau of Land Management), and PROBES (Processes and Resources of the Bering Sea Shelf, funded by the Polar Programs Division of the National Science Foundation). Both OCSEAP and PROBES have concentrated field work on the shelf, and together the resources available for shelf research have increased tenfold or more. OCSEAP aims for a broad understanding of the shelf to assess hazards of petroleum development, while PROBES aims to understand the southeastern shelf ecosystem by concentrating on the trophic web of the Alaska or walleye pollock [Theragra chalcogramma). Justifica- tion for such large research programs was the realiza- tion of man's impact on coastal environments and of the importance of the continental shelves and their waters to man. In the Bering Sea, the potential petroleum resource and the renewable fisheries resource stimulated research requirements and subsequent funding. The seven chapters in this section reflect both the foundation provided by the earlier work and the direction of research that the influence of new instrumentation, new ideas, and new funding has produced. Work has continued in the deep Bering Sea, and I will review the progress there before outlining the physical oceanography section of this book. Then, in the Ught of the work recently completed, I will discuss some research needs and probable progress in Bering Sea oceanography in the next decade, DEEP BERING SEA By the time of the Hood and Kelley (1974) volume the patterns of the mean circulation and the mean hydrographic distributions were established, and something about their annual and interannual vairia- tions was known. Hughes et al. (1974), Favorite (1974), Favorite and Ingraham (1974), Favorite et al. (1976), Ohtani (1973), and Arsenev (1967) showed a basically cyclon
