NMML Killer Whale Vessel Suvey, Kodiak Island, 1992
Entry ID: seamap155

Abstract: From 9 July to 22 August, 1992, a part of a larger study, the waters
surrounding Kodiak Island were 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 ... View entire text
