Distribution, Abundance, Behavior, and Bioacoustics of Endangered Whales in the Alaskan Beaufort and Eastern Chukchi Seas, 1979-86.

Aerial surveys and acoustic recordings of bowhead whales and, secondarily, other marine mammals were made from mid-August 1986 through October 1986 in the eastern Chukchi and Alaskan Beaufort Sea. In addition, a shore-based acoustic station was established on Barter Island, Alaska to record the call...

Description
Summary:Aerial surveys and acoustic recordings of bowhead whales and, secondarily, other marine mammals were made from mid-August 1986 through October 1986 in the eastern Chukchi and Alaskan Beaufort Sea. In addition, a shore-based acoustic station was established on Barter Island, Alaska to record the calls of migrating bowhead whales as they passed through the eastern Alaskan Beaufort Sea. Survey results and observations on bowhead whale distribution, relative abundance and density, migration patterns, general behavior, and sound production are presented. Presented here also are survey results and observations on gray whale distribution, relative abundance, and general behavior. Incidental sightings of all marine mammals are reported.
