The Antarctic Peninsula is undergoing greater warming than almost anywhere on Earth, a condition perhaps associated with human-induced greenhouse effects. According to the cover article published in the August 4 issue of the journal Nature, the spectacular collapse of Antarctica's Larsen B Ice Shelf, an area roughly the size of Rhode Island, is unprecedented during the past 10,000 years. Eugene Domack, professor of geosciences at Hamilton College and the author of the paper, has been the lead scientist of a multi-institutional, international effort that combines a variety of disciplines in examining the response of the Antarctic Peninsula to modern warming. Domack says, "Our work contributes to the understanding of these changes -- where they are occurring first and with greatest magnitude and impact upon the environment."

The chance discovery of a vast ecosystem beneath the collapsed Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarctica's floating ice shelves and further probe the origins of life in extreme environments. Researchers discovered the sunless habitat after reviewing an underwater video study examining a deep glacial trough in the northwestern Weddell Sea following the sudden Larsen B shelf collapse in 2002.
