Base Camp: West Antarctica

Stretching off the edge of the continent, 1,400 miles west of Antarctica's McMurdo Station, is Pine Island Glacier (PIG)—a massive river of ice 190 miles wide and 30 miles long that satellite measurements reveal is rapidly shrinking in size. Much of the glacier rests on a bed below sea level and global sea levels could increase by three feet or more if the glacier melted completely. The rate of ice loss on the glacier has increased rapidly in recent years, and scientists believe shifting warm water rising from the adjacent deep ocean and circulating in the surrounding Amundsen Sea are rapidly melting the underside of the glacier's floating edge—the ice shelf. To be certain requires measurements taken beneath this floating ice. That's where NASA polar scientist Robert Bindschadler comes in. In 2008, Bindschadler led an expedition to the remote ice shelf by plane, but the dangers of landing on the crevassed surface prevented his team from collecting data. This fall Bindschadler will return via helicopter. The plan on arrival: drill 1,640 feet below the surface and deploy a specially designed instrument that will start continuous measurements of the shifting ocean waters beneath the glacier.
