The hysteresis of the Antarctic Ice Sheet
Nature, 2020 More than half of Earth's freshwater resources are held by the Antarctic Ice Sheet, which thus represents by far the largest potential source for global sea-level rise under future warming conditions1. Its long-term stability determines the fate of our coastal cities and cultural heritage.

Bacteria beneath the West Antarctic Ice Sheet
Environmental Microbiology, 2009Summary Subglacial environments, particularly those that lie beneath polar ice sheets, are beginning to be recognized as an important part of Earth's biosphere. However, except for indirect indications of microbial assemblages in subglacial Lake Vostok, Antarctica, no sub‐ice sheet environments have been shown to ...

Changes in the West Antarctic Ice Sheet
Science, 1991The portion of the West Antarctic ice sheet that flows into the Ross Sea is thinning in some places and thickening in others. These changes are not caused by any current climatic change, but by the combination of a delayed response to the end of the last global glacial cycle and an internal instability. The near-future impact of the ice sheet on global

Antarctica is the fifth largest continent on the Earth with an area of 14,200,000 km2. About 98% of the surface of Antarctica is covered by an ice sheet that is 2,000 m thick on average. The volume of the ice sheet has changed in the course of time and reached a maximum during the late Wisconsin (Weichselian) ice age about 20,000 years ago.

Mass balance of the Antarctic ice sheet
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006The Antarctic contribution to sea-level rise has long been uncertain. While regional variability in ice dynamics has been revealed, a picture of mass changes throughout the continental ice sheet is lacking. Here, we use satellite radar altimetry to measure the elevation change of 72% of the grounded ice sheet during the period 1992–2003 ...

West Antarctic Ice Sheet Collapse?
Science, 1997Charles R. Bentley (Perspectives, [21 Feb., p. 1077][1]) suggests that a useful estimate of the probability of a West Antarctic ice-sheet collapse in the next 100 years can be obtained by assuming it to be a random event occurring once every 100,000 years.

Lakes Beneath the Antarctic Ice Sheet
Nature, 1973THE technique of radio-echo sounding of polar ice sheets is now well established1–3, and three seasons of radio-echo sounding from long range aircraft of the US Navy have been completed under a joint programme of the Scott Polar Research Institute and the US National Science Foundation.

Antarctic ice sheet melting and climate
Science, 2020Climate Change The massive West Antarctic Ice Sheet (WAIS) is now melting at an accelerated rate in response to anthropogenic greenhouse gas emissions, and exactly how this will affect global climate remains poorly understood. Widely available predictive global climate models do not adequately account for ice sheet physics.
