Aerial Surveys of Endangered Whales in the Northern Bering, Eastern Chukchi, and Alaskan Beaufort Seas, 1984: with a Six Year Review, 1979-1984.
Aerial surveys and acoustic recordings of bowhead whales and, secondarily, other marine mammals were made from mid-April through mid-May and from mid-July through October 1984 in the northern Bering, eastern Chukchi, and Alaskan Beaufort Seas. Survey results and observations of bowhead distribution,...
