Liquid meltwater can sometimes flow deep below the Greenland Ice Sheet in winter, not just in summer, according to National Science Foundation-funded research published in the American Geophysica...
Antarctic ice cliffs may not contribute to ice-sheet instability as much as predicted（图）
Antarctic ice cliff contribute ice-sheet instability

Antarctica's ice sheet spans close to twice the area of the contiguous United States. Its land boundary is buttressed by massive, floating ice shelves extending hundreds of miles out over the frigid w...
Ice is sliding toward edges of Greenland Ice Sheet（图）
Ice toward edges Greenland Ice Sheet
font style='font-size:12px;'>
2019/10/23
Ice on the Greenland Ice Sheet doesn’t just melt. The ice slides rapidly across its bed toward the ice sheet’s edges. As a result, ice is moving to high-melt marginal zones more rapidly than previousl...
THE RESEARCH ON ELEVATION CHANGE OF ANTARCTIC ICE SHEET BASED ON CRYOSAT-2 ALIMETER

2018/5/15
In this paper, the Cryosat-2 altimeter data distributed by the ESA, and these data are processed to extract the information of the elevation change of the Antarctic ice sheet from 2010 to 2017. Firstl...
Massive East Antarctic Ice Sheet Has History Of Instability（图）
East Antarctic Ice Sheet History Instability

2017/12/19
The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet), more than any other ice sheet on the planet. It's also thought to be among the most stable, n...
Methane-eating bacteria in lake deep beneath Antarctic ice sheet may reduce greenhouse gas emissions（图）
Methane-eating bacteria lake deep Antarctic ice sheet reduce greenhouse gas emissions

2017/9/1
An interdisciplinary team of researchers funded by the National Science Foundation (NSF) has concluded that bacteria in a lake 800 meters (2,600 feet) beneath the West Antarctic Ice Sheet may digest m...
Sea-level rise from Antarctic ice sheet could double
Sea-level rise Antarctic ice sheet double
font style='font-size:12px;'>
2016/4/13
An ice sheet model that includes previously underappreciated processes indicates that sea level may rise almost 50 feet by 2500 due to Antarctic ice sheet melting if greenhouse gas emissions continue ...
Mass-conserving subglacial hydrology in the Parallel Ice Sheet Model version 0.6
Parallel Ice Sheet Model subglacial hydrology

2015/8/6
We describe and test a two-horizontal-dimension
subglacial hydrology model which combines till with a distributed system of water-filled, linked cavities which open
through sliding and close t...

2015/7/15
A few decades ago, Antarctic ice sheets were expected to grow as the
atmosphere warmed and increasing poleward moisture transport added snowfall
to regions that would remain below freezing year-ro...

forcing led to demise Laurentide ice sheet
font style='font-size:12px;'>
2015/7/13
A new study has found that the massive Laurentide ice sheet that covered Canada during the last ice age initially began shrinking through calving of icebergs, and then abruptly shifted into a new regi...
Comparing a thermo-mechanical Weichselian Ice Sheet reconstruction to reconstructions based on the sea level equation: aspects of ice configurations and glacial isostatic adjustment
thermo-mechanical Weichselian Ice Sheet reconstruction to reconstructions sea level equation ice configurations glacial isostatic adjustment
font style='font-size:12px;'>
2015/1/6
In this study we compare a recent reconstruction of the Weichselian Ice Sheet as simulated by the University of Maine ice sheet model (UMISM) to two reconstructions commonly used in glacial isostatic ...
