Entry ID: seamap138

[ Get Data ]

Abstract: From 13 July to 24 August, 1993, a part of a larger study, waters off
the Alaskan Peninsula were surveyed for killer whales (Orcinus orca) from the
NOAA Glorita using line transect methodology. To provide adequate coverage
throughout the area, the study was limited to areas of known killer whale
concentrations. The vessel was 44.8 m (147 ft) long and had a bridge height of
8.8 m (29 feet).

Purpose: The objectives of this study were as follows: 1) Develop a
photographic identification catalogue of each killer whale encountered, and its
pod, to determine pod identity, distribution, and movements relative to annual
survey effort. 2) Obtain minimum population estimated of killer whales in the
southeastern Bering Sea, central/eastern Aleutian Islands, western Gulf of
Alaska (including Prince ... View entire text
