[ Update this Record ]

Summary

Abstract: From 9 July to 22 August, 1992, a part of a larger study, the Alaskan
Peninsula was surveyed for killer whales (Orcinus orca) from the NOAA Brielyn
Marie 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 36.5 m (113 ft) long and had a bridge height of 6.0 m (18.5
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
central/eastern Aleutians and the south side of the Alaskan peninsula. 3)
Establish baseline data for detecting annual changes in abundance.
