PI(s):

Robin E. Bell

Scientists from several nations are working together to launch a flagship program to explore a major mountain range buried by a large continental ice sheet and bounded by numerous subglacial lakes.

Researchers Unravel Origins of Antarctica's Ice-Covered Mountains

November 16, 2011

Buried below more than a mile of ice, Antarctica’s Gamburtsev Mountains have baffled scientists since their discovery in 1958. How did the mountains get there, and what role did they play in the spread of glaciers over the continent 30 million years ago? In the latest study on the mountains, scientists this week in the journal Nature say they have pieced together the puzzle of the origins and evolution of this mysterious mountain chain.
Some Antarctic Ice is Forming from Bottom

March 02, 2011

Scientists working in the remotest part of Antarctica have discovered that liquid water locked deep under the continent’s coat of ice regularly thaws and refreezes to the bottom, creating as much as half the thickness of the ice in places, and actively modifying its structure.

Warming Climate Drives Plankton and Penguins Poleward

Adélie penguins are flocking closer to the South Pole. A new study in the leading journal Science explains why: they’re following the food supply, which is moving southward with changing climate.
Glacial Earthquakes Point to Rising Temperatures in Greenland

March 23, 2006

Seismologists at Columbia University and Harvard University have found a new indicator that the Earth is warming: "glacial earthquakes" caused when the rivers of ice lurch unexpectedly and produce temblors as strong as magnitude 5.1 on the moment-magnitude scale, which is similar to the Richter scale. Glacial earthquakes in Greenland, the researchers found, are most common in July and August, and have more than doubled in number since 2002.
