Antarctic ice cliffs may not contribute to ice-sheet instability as much as predicted(图)
Antarctic ice cliff contribute ice-sheet instability
2019/11/5
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...

Instability in Antarctic ice projected to increase likelihood of worst-case sea level rise(图)
Instability Antarctic ice projected worst-case sea level rise
2019/10/23
Images of vanishing Arctic ice are jarring, but the region’s potential contributions to sea level rise are no match for Antarctica’s. Now, a study says that instability hidden in Antarctic ice increas...
THE RESEARCH ON ELEVATION CHANGE OF ANTARCTIC ICE SHEET BASED ON CRYOSAT-2 ALIMETER
Antarctic Ice Sheet, Cryosat-2,Satellite Altimetry,DEM, Crossover Adjustment,Kriging Interpolation, Intersection
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
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 ...
The anticipated melting of the massive West Antarctic Ice Sheet could be slowed by two big factors that are largely overlooked in current computer models, according to a new study.The findings, publis...
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...

in recent years, mass loss from the Antarctic
ice Sheet has contributed nearly 0.5 mm yr–1
to global mean sea level rise, about one-sixth of
the current rate (church et al., 2011). Around

The Larsen C Ice Shelf—whose neighbours Larsen A and B, collapsed in 1995 and 2002—is thinning from both its surface and beneath, according to an international study published in the journal The ...
RECONSTRUCTING PAST ANTARCTIC ICE FLOW PATHS IN THE ROSS EMBAYMENT, ANTARCTICA USING SAND PETROGRAPHY, PARTICLE SIZE AND DETRITAL ZIRCON PROVENANCE
Provenance Antarctica zircons Till
2015/1/16
Tills for this study were analyzed from sites in East Antarctica (EA), West Antarctica (WA) and along a transect in the Ross Sea. Particle size, sand petrography, and detrital zircons were used to pro...
