History, mass loss, structure, and dynamic behavior of the Antarctic Ice Sheet

Science, 2020
Antarctica contains most of Earth’s fresh water stored in two large ice sheets. The more stable East Antarctic Ice Sheet is larger and older, rests on higher topography, and hides entire mountain ranges and ancient lakes.

West Antarctic Ice Sheet Collapse?

Science, 1997
Charles 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, 1973
THE 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.

Statistics and the Future of the Antarctic Ice Sheet

CHANCE, 2017
One of the enduring symbols of the impact of climate change is that of a polar bear drifting in the sea, alone on its own piece of ice.

Is the East Antarctic ice sheet stable?

Quaternary Research, 2011
AbstractThe Greenland and East and West Antarctic ice sheets are assessed as being the source of ice that produced an Eemian sea level 6 m higher than present sea level. The most probable source is total collapse of the West Antarctic Ice Sheet accompanied by partial collapse of the adjacent sector of the East Antarctic Ice Sheet in direct contact with

Bacteria beneath the West Antarctic Ice Sheet

Environmental Microbiology, 2009
SummarySubglacial 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 support microbial ecosystems.

ICE CORES | Dynamics of the East Antarctic Ice Sheet

2007
The East Antarctic Ice Sheet has a maximum thickness of more than 4 km, and covers the Antarctic continent between longitudes 30° W and 165° E. The ice flows down the surface slopes from high interior domes toward the coastline through two processes: (i) by temperature-dependent quasi-viscous internal deformation, mostly shear parallel to the bed, and (

Future of the West Antarctic Ice Sheet

Science, 1998
A collapse of the Antarctic Ice Sheets would raise the sea level by 5 meters and, depending on how quickly it occurred, would pose an enormous threat to global economy and ecology. How stable are these volumes of ice? In his Perspective, Bindschadler discusses recent efforts to model the behavior of the West Antarctic Ice Sheet on the basis of data on ...
