Abstract: | After having been one of the primary targets of commercial whaling during the 20th century, Antarctic blue whales (Balaenoptera musculus intermedia) are still listed as critically endangered by the International Union for Conservation of Nature and many aspects of their distribution and migration patterns remain poorly understood to date. This dissertation investigates spatio-temporal patterns in the (acoustic) presence of Antarctic blue whales in the Atlantic sector of the Southern Ocean and in the South Atlantic Ocean in order to contribute to a better understanding of their distribution patterns and migratory behavior. It adds to increasing evidence that Antarctic blue whales inhabit both high- and low-latitude areas in the Southern Hemisphere year-round and thereby indicates that a diverse migratory repertoire is rather the rule than the exception in Antarctic blue whales. An improved understanding of the distribution and migration of Antarctic blue whales can aid the development of effective conservation strategies for this critically endangered species, such as the designation of marine protected areas in Antarctic blue whale key habitats. |
