Changes in the Antarctic sea ice ecosystem: potential effects on krill and baleen whales
The annual formation and loss of some 15 million km 2 of sea ice around the Antarctic significantly affectsglobal ocean circulation, particularly through the formation of dense bottom water.As one of the most profound seasonalchanges on Earth, the formation and decay of sea ice plays a major role in...

It is also likely to be impactedby climate change, potentially changing the productivity of the Antarctic region. The sea ice zone supports much wildlife,particularly large vertebrates such as seals, seabirds and whales, some exploited to near extinction.
