The Greenland ice sheet (Greenlandic: Sermersuaq) is a vast body of ice covering 1710000 square kilometres (660000 sq mi) roughly 80% of the surface of Greenland. It is the second largest ice body in the world after the Antarctic Ice Sheet. The ice sheet is almost 2400 kilometres (1500 mi) long in a north-south direction and its greatest width is 1100 kilometres (680 mi) at a latitude of 77°N near its northern margin. The mean altitude of the ice is 2135 metres (7005 ft).
