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.

The Advisory Committee on Antarctic Names approved the name in 1962. West Antarctica is mostly covered by a massive ice sheet referred to as the West Antarctic Ice Sheet. In recent decades, this ice sheet has shown signs of decreasing mass. [4] The geologic history of West Antarctica was summarized in a 2020 publication. [5]
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 ...
The Antarctic ice sheet is melting in a new, worrying way not taken into account by current models of future sea level rise, according to a new study. ... professor of Earth system science at the ...
Scientists say warming trend in West Antarctica is already on a trajectory that cannot be reversed under various emission scenarios Future melting of Antarctic Ice Sheet ‘unavoidable ...
West Antarctic Rift System (between red dash lines). Dots are geologic drill holes. Insert map shows approximate extent. Exploration of the geology of the West Antarctic Rift System is limited because apart from peaks of the Transantarctic Mountains that protrude above the ice, much of the region is covered by the Ross Ice Shelf and the vast West Antarctic Ice Sheet.
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 ...
Radioglaciology is the study of glaciers, ice sheets, ice caps and icy moons using ice penetrating radar.It employs a geophysical method similar to ground-penetrating radar and typically operates at frequencies in the MF, HF, VHF and UHF portions of the radio spectrum.
