Southern bottlenose whales are the most common beaked whales sighted in Antarctic waters, and are clearly abundant there. Kasamatsu and Joyce (1995) estimated an abundance of 599,300 (CV=15%) beaked whales south of the Antarctic Convergence in January, most of which were considered to be southern bottlenose whales. This estimate of abundance is likely underestimated because the methods used did not account for the fact that beaked whales dive for long periods and are inconspicuous when they surface (Barlow 1999).
