It is the largest of Earth's two current ice sheets, containing 26.5 million cubic kilometres (6,400,000 cubic miles) of ice, which is equivalent to 61% of all fresh water on Earth. Its surface is nearly continuous, and the only ice-free areas on the continent are the dry valleys, nunataks of the Antarctic mountain ranges , and sparse coastal ...
Location and diagram of Lake Vostok, a prominent subglacial lake beneath the East Antarctic Ice Sheet.. East Antarctic Ice Sheet is located directly above the East Antarctic Shield – a craton (stable area of the Earth's crust) with the area of 10,200,000 km 2 (3,900,000 sq mi), which accounts for around 73% of the entire Antarctic landmass.

A map of West Antarctica. The total volume of the entire Antarctic ice sheet is estimated at 26.92 million km 3 (6.46 million cu mi), [2] while the WAIS contains about 2.1 million km 3 (530,000 cu mi) in ice that is above the sea level, and ~1 million km 3 (240,000 cu mi) in ice that is below it.

Antarctica is actually gaining ice mass thanks to snow and instead of driving sea level rise, it may actually be slowing it down. Antarctica is actually gaining ice mass thanks to snow and instead ...
The Transantarctic Mountains bisect the continental ice sheets, with different ice flow dynamics on either side. Radarsat (radar images collected by orbiting satellites) is being used to map the ice sheets. Ice sheet flow into the ocean is increasing and in western Antarctica, the ice stream is draining into the Ross Ice Shelf with marked ...
<p>Chances are you make it through most days without sparing a thought for Antarctica. At just over 5.4 million square miles, it's a massive chunk of land that is nearly twice the size of ...
In January 2023, a massive piece of Antarctica's Brunt Ice Shelf — a chunk about the size of two New York Cities — broke free. The Brunt Ice Shelf lies across the Weddell Sea from the site of ...
Greenland ice sheet as seen from space. An ice sheet is a body of ice which covers a land area of continental size - meaning that it exceeds 50,000 km 2. [4] The currently existing two ice sheets in Greenland and Antarctica have a much greater area than this minimum definition, measuring at 1.7 million km 2 and 14 million km 2, respectively.
