Summary
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 ...  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 ...
