Draft of probable environmental impacts of offshore oil and gas development in the Beaufort Sea off the north coast of Alaska, including oil spills and effects on marine mammals, and effects on commercial and subsistence fishing.
One egg from each of 440 clutches of eggs of 19 species of Alaskan seabirds collected in 1973-76 was analyzed for organochlorine residues. Both frequency of occurrence and concentration of residues in the eggs differed geographically and by species, apparently reflecting non-uniform distribution of organochlorines in the environment, dissimilar feeding habits and migration patterns of the species, or metabolic differences among the species.
This draft report considers the potential environmental impact on water and air quality, marine mammals, sea birds, local economics and fisheries, of several possible levels of exploration for offshore oil and natural gas in the Navarin Basin (Bering Sea) on the outer Continental Shelf off southwest Alaska.
