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 ...
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...
Surprisingly high geothermal heating revealed beneath West Antarctic Ice Sheet

2015/8/4
The amount of heat flowing toward the base of the West Antarctic ice sheet from geothermal sources deep within the Earth is surprisingly high, according to a new study led by UC Santa Cruz researchers...
Formulation, calibration and validation of the DAIS model (version 1), a simple Antarctic ice sheet model sensitive to variations of sea level and ocean subsurface temperature
Formulation calibration validation DAIS model simple Antarctic ice sheet model sensitive sea level ocean subsurface temperature

The DCESS (Danish Center for Earth System Science) Antarctic Ice Sheet (DAIS) model is presented. Model hindcasts of Antarctic ice sheet (AIS) sea level equivalent are forced by reconstructed Antarcti...
Confirmed: 800 meters beneath Antarctic ice sheet, subglacial lake holds viable microbial ecosystems（图）

In a finding that has implications for life in other extreme environments, both on Earth an...
Antarctic ice sheet is result of CO2 decrease, not continental breakup
Antarctic ice sheet result of CO2 decrease not continental breakup
2014/8/14
Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decre...
Getting around Antarctica: new high-resolution mappings of the grounded and freely-floating boundaries of the Antarctic ice sheet created for the International Polar Year
Antarctica the grounded freely-floating boundaries
2014/5/20
Two ice-dynamic transitions of the Antarctic ice
sheet – the boundary of grounded ice features and the freely-floating boundary – are mapped at 15-m resolution by par-ticipants of the International P...
Antarctic ice-sheet response to atmospheric CO2 and insolation in the Middle Miocene
Antarctic ice-sheet Middle Miocene atmospheric CO2
2009/12/3
Foraminiferal oxygen isotopes from deep-sea sediment cores suggest that a rapid expansion of the Antarctic ice sheet took place in the Middle Miocene around 13.9 million years ago. The origin for thi...
Ice thinning, upstream advection, and non-climatic biases for the upper 89% of the EDML ice core from a nested model of the Antarctic ice sheet
upstream advection EDML ice core Antarctic ice sheet
2008/11/7
A nested ice flow model was developed for eastern Dronning Maud Land to assist with the dating and interpretation of the EDML deep ice core. The model consists of a high-resolution higher-order ice dy...
