    the Bering Sea including the Aleutian Island Archipelago, and the Chukchi and Beaufort Seas in the Arctic. Deep corals are widespread throughout Alaska, including the continental shelf and upper slope of the Gulf of Alaska, the Aleutian Islands, the eastern Bering Sea, and extending as far north as the Beaufort Sea. The Bering Sea (Russian: Бе́рингово мо́ре, tr. Béringovo móre) is a marginal sea of the Pacific forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and The Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelves. Estimated biomass of Pacific cod in the eastern Bering Sea and Aleutian Islands (note: most catch is taken in the Bering Sea) increased by an order of magnitude during the late s to early s and has been declining steadily since , with a fairly steady increase in exploitation rate until (see Figures b and d). The biomass.
