Because the East Antarctic ice sheet is over 10 times larger than the West Antarctic ice sheet and located at a higher elevation, it is less vulnerable to climate change than the WAIS. In the 20th century, EAIS had been one of the only places on Earth which displayed limited cooling instead of warming, even as the WAIS warmed by over 0.1 °C ...
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.

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.
The Ross Ice Shelf is the main outlet for several major glaciers draining the West Antarctic Ice Sheet, which contains the equivalent of 5 m of sea level rise in its above-sea-level ice." The report added that observations of "iceberg calving" on the Ross Ice Shelf are, in their opinion, unrelated to its stability. [10]
The WAIS Divide ice core project (West Antarctic Ice Sheet Divide ice core project) investigated past climate changes, ice sheet dynamics and cryobiology. The project was completed by the United States Antarctic Program (USAP) and was funded by the National Science Foundation (NSF).
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different ...
Some named Antarctic iceshelves. Location. The calving of A-38 off Ronne ice shelf. The A38-B iceberg splits. Rapid sea ice breakup along the Ronne-Filchner ice shelf, January 2010. The Filchner–Ronne Ice Shelf or Ronne–Filchner Ice Shelf is an Antarctic ice shelf bordering the Weddell Sea.
