The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick, and over 3 km (1.9 mi) thick at its maximum. [ 96 ] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N ...
The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi). It is the largest of Earth's two current ice sheets, containing 26.5 million cubic kilometres (6,400,000 cubic miles) of ice ...
The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick, and over 3 km (1.9 mi) thick at its maximum. [2] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N, near ...
A vast area of the Antarctic Ice Sheet – Thwaites Glacier – continues to retreat and much of it could be lost by the 23rd century, experts say. The glacier spans an area equal to the island of ...
The East Antarctic Ice Sheet (EAIS) lies between 45° west and 168° east longitudinally. It was first formed around 34 million years ago, [3] and it is the largest ice sheet on the entire planet, with far greater volume than the Greenland ice sheet or the West Antarctic Ice Sheet (WAIS), from which it is separated by the Transantarctic ...
The West Antarctic Ice Sheet (WAIS) is the segment of the continental ice sheet that covers West Antarctica, the portion of Antarctica on the side of the Transantarctic Mountains that lies in the Western Hemisphere. It is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice ...
The Ross Ice Shelf is one of many such shelves. It reaches into Antarctica from the north, and covers an area of about 520,000 km 2 (200,000 sq mi), nearly the size of France. [2][3] The ice mass is about 800 km (500 mi) wide and 970 km (600 mi) long. In some places, namely its southern areas, the ice shelf can be almost 750 m (2,450 ft) thick.
Animation of the canyon Topographic map of the bedrock under the ice. The Grand Canyon of Greenland is a tentative canyon of record length discovered underneath the Greenland ice sheet as reported in the journal Science on 30 August 2013 (submitted 29 April 2013), by scientists from the University of Bristol led by Jonathan Bamber, University of Calgary, and University of Urbino, who described ...
