NMML Harbor Porpoise Vessel Survey, SE Alaska, Summer 1992
Entry ID: seamap150

Abstract: In summer 1992, the south side of the Alaskan Peninsula and the
Kodiak Archipelago were surveyed for harbor porpoise (Phocoena phocoena) from
the NOAA John N. Cobb using line transect methodology. The shipboard platform
was 28.36 m (93 ft) in length with a bridge height of 4.27 m (14 ft). To obtain
data on seasonal movements of porpoise, a limited number of transects were ... View entire text

Purpose: Although harbor porpoises, Phocoena phocoena, are known to occur
throughout Alaska waters (Fiscus et al. 1976; Leatherwood and Reeves 1978;
Lawry et al. 1982; Leatherwood et al. 1983), few estimates of abundance exist.
In 1991, the National Marine Mammal Laboratory initiated a 3-yr study on Alaska
harbor porpoises. The objectives of this program were to: 1) Obtain minimum
