Summary
Abstract: Visual line-transect surveys for cetaceans were conducted in the
central-eastern Bering Sea (CEBS) from 5 July to 5 August 1999, in association
with a pollock stock assessment survey aboard the NOAA ship Miller Freeman.
Observers scanned for cetaceans with 25x (Big Eye) binoculars form the flying
bridge (platform height = 12m) at survey speeds of 18.5-22 km h-1 (10-12
knots). Transect survey ... View entire text

Purpose: Cetacean distribution and abundance in the Bering Sea is poorly
described, with even recent reviews of cetaceans' role in the ecosystem reliant
on data from the commercial whaling era (e.g. Springer et al., 1999; Springer,
McRoy, & Flint, 1996). Commercial harvests of baleen whales (mysticetes) were
extensive in the North Pacific and Bering Sea (Miyashita, Kato, & Kasuya,
1995), especially between ... View entire text
