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.

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 geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent , located in the Earth 's southern hemisphere , is centered asymmetrically around the South Pole and largely south of the Antarctic Circle .
Record-breaking low levels of sea ice around Antarctica in 2023 may have been influenced by climate change, scientists have said. Researchers at the the British Antarctic Survey (BAS) analysed ...
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.

Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
Dome Argus is located on the massive East Antarctic Ice Sheet and is the highest ice feature of Antarctica. [3] Dome A is a lofty ice prominence, the highest rooftop of the Antarctic Plateau, and the elevation visually is not noticeable. Below this enormous dome, underneath at least 2,400 m (7,900 ft) of ice sheet, lies the Gamburtsev Mountain ...
