Aerial Surveys of Endangered Whales in the Northern Bering, Eastern Chukchi and Alaskan Beaufort Seas, 1983: with a Five Year Review, 1979-1983.
Abstract
Aerial surveys and acoustic recordings of bowhead whales and, secondarily, other marine mammals were made from mid-April through May and from mid-July through mid-October 1983 in the northern Bering, eastern Chukchi, and Beaufort Seas. Survey results and observations on bowhead distribution, relative abundance, migration patterns, general behavior, and sound production for spring and fall seasons are presented. Presented here are survey results and observations on grey whale distribution, relative abundance, and general behavior for July. Incidental sightings of all marine mammals are reported. (Author)
