Primary biological productivity is greatest in the southern extremities at the entrance to the Bering Strait; moreover, it is also high along the Alaskan coastal zone and the Russian Chukotka coastline, particularly near Point Hope and Cape Lisburne. Elevated benthic biomass is found in the northeastern and south-central Chukchi Basin.
In addition to the Polar bear, there are a number of other marine mammals that frequent the Chukchi Sea basin. Walruses, for example, appear in large numbers in the Chukchi Sea in the summer, having migrated through the Bering Strait. Ribbon seals appear in considerable numbers in the coastal zone of the Chukchi Sea in the warmer months, congregating along lagoons and estuaries of the sea margin. Beluga, Bowhead whales,Gray whales,Fin whales, Harbour porpoises, and Spotted seals are other marine mammals found in the the Chkchi Sea.
The Chukchi Basin contains an estimated thirty billion barrels of oil and natural gas at subsea locations. See: Offshore drilling in the Arctic: background and issues for the future consideration of oil and gas activities
