NASA | Warm Ocean Currents Cause Majority of Ice Loss from Antarctica

Warm ocean currents attacking the underside of ice shelves are the dominant cause of recent ice loss from Antarctica. This animation shows the circulation of ocean currents around the western Antarctic ice shelves. The shelves are indicated by the rainbow color; red is thicker (greater than 550 meters), while blue is thinner (less than 200 meters)..
