In glaciology, an ice sheet, also known as a continental glacier, [2] is a mass of glacial ice that covers surrounding terrain and is greater than 50,000 km 2 (19,000 sq mi). [3] The only current ice sheets are the Antarctic ice sheet and the Greenland ice sheet. Ice sheets are bigger than ice shelves or alpine glaciers.
Multiple studies of Antarctica indicate growing ice sheet instability, especially in the Amundsen Sea Embayment, where the Thwaites, Pine Island, Smith, Kohler, Pope, and Haynes Glaciers drain the central West Antarctic Ice Sheet.

Overview. What is an ice sheet? A portion of the West Antarctic Ice Sheet drains into the ice-covered Bellingshausen Sea via an S-shaped glacier. The top of the glacier is rippled with crevasses, indicating the ice is flowing over steep terrain. — Credit: NASA Operation IceBridge.
