Warming waters along the Antarctic Peninsula have opened the door to shell-crushing king crabs that threaten a unique ecosystem on the seafloor, according to new research by a US-Sweden team of marine researchers.
In a complex example of science diplomacy, teams of U.S. and Swedish scientists are sailing this month aboard two research vessels to study the ecology of the Amundsen Sea, one of the least-explored and most productive bodies in Antarctic waters, and to gauge the potential effects of a changing climate on the Southern Ocean.
