Record #188452:

Cetacean occurrence patterns in the Amundsen and Southern Bellingshausen Sea sector, Southern Ocean / David G. Ainley, and 3 others.

Title: Cetacean occurrence patterns in the Amundsen and Southern Bellingshausen Sea sector, Southern Ocean / David G. Ainley, and 3 others.
Author(s): Ainley, David G.
Date: 2007.
Publisher: [San Francisco, CA]: Society for Marine Mammalogy
Abstract: Reports results of icebreaker-based survey in rarely-visited pack ice and adjacent waters of Amundsen and southern Bellingshausen seas during autumn 1994. Describes factors that affected occurrence patterns of cetaceans and especially of minke whales Balaenoptera bonaerensis, which were most abundant whale species encountered, and compares to results of other surveys both in deep and peripheral ice pack. Statistical analysis showed that probability of sighting minke, as well as killer whales, was related to proximity of coastal polynyas in early autumn, switching offshore to marginal ice zone (MIZ) once waters within pack began to freeze persistently later in season. Density index was strongly related to ice concentration in inverse relationship. Strong relationship to polynyas and MIZ indicate that sea-ice divergence altered by decadal or longer-term climate change could affect any apparent, long-term trends evident in this species' abundance if surveyed only in open or near-to-ice waters. Discusses possibility that minke whale's pagophilic nature could have been encouraged by large-scale industrial whaling and by competition with species more characteristic of open waters and outer MIZ; and may have protected population to some degree during industrial whaling, resulting in much greater abundance of this species now compared to other targeted species.
