How do fish in the Southern Ocean keep from freezing?

Research

The ICEFISH 2004 Cruise and future follow-on cruises are considered to be the first comprehensive international survey of the fishes of the Sub-Antarctic marine habitat. In a world experiencing changes in global climate, loss of biological diversity, and depletion of marine fisheries, the Antarctic, Sub-Antarctic and their biota offer compelling natural laboratories for understanding the evolutionary impacts of these processes. The proposed work will contribute to development of a baseline understanding of these sensitive ecosystems, one against which future changes in species distribution and survival may be evaluated judiciously.

From May July, 2004, a team of researchers will collect specimens of lower latitude fishes in order to relate the evolution, physiology, biochemistry and population dynamics of high-latitude Antarctic fishes of the suborder Notothenioidei to the transitional fish fauna of the Sub-Antarctic.
