ANTARCTIC ICE SHEET SURFACE MASS BALANCE ESTIMATES FROM 2003 TO 2015 USING ICESAT AND CRYOSAT-2 DATA
Antarctica Mass Balance ICESat CryoSat-2
2016/11/30
An assessment of Antarctic ice sheet surface mass balance from 2003 to 2015 has been carried out using a combination of ICESat data from 2003 to 2009 and CryoSat-2 data from 2010 to 2015. Both data se...
EXTRACTION OF ICE SHEET LAYERS FROM TWO INTERSECTED RADAR ECHOGRAMS NEAR NEEM ICE CORE IN GREENLAND
Cryosphere Ice sheet layering Radar echo sounding Sub-glacial ice flow NASA IceBridge
2016/11/23
Accumulation of snow and ice over time result in ice sheet layers. These can be remotely sensed where there is a contrast in electromagnetic properties, which reflect variations of the ice density, ac...

Glaciers and ice sheets are the most important hydrological resources on Earth and play an important role in the global
climate system. The Greenland Ice Sheet stores 9 % of the Earth’s fresh water s...
NSF-funded Antarctic drilling team is first to bore through hundreds of meters of ice to where ice sheet, ocean and land converge
NSF-funded Antarctic drilling team hundreds of meters of ice to where ice sheet ocean land converge
2015/3/4
Using a specially designed hot-water drill to cleanly bore through a half mile of ice, a National Science Foundation (NSF)-funded team of researchers has become the first ever to reach and sample the ...
The highest-resolution satellite images ever taken of that region are making their debut. And while each individual pixel represents only one moment in time, taken together they show the ice sheet as ...

2014/10/9
A team led by scientists at the University of Texas at Austin's Institute for Geophysics has for the first time directly observed multiple parts of Greenland's subglacial plumbing system and how that ...
West Antarctic Ice Sheet collapse is under way
West Antarctic Ice Sheet collapse under way
2014/6/12
The West Antarctic Ice Sheet, which holds enough water to raise global seas by several feet, is thinning. Scientists have been warning of its collapse, based on theories, but with few firm predictions...
COMPARISON OF MICROWAVE BACKSCATTER ANISOTROPY PARAMETERISATIONS OVER THE ANTARCTIC ICE SHEET
Snow Ice Glaciology Research Active Microwave Satellite
2014/4/30
The Antarctic Ice Sheet exhibits a strong anisotropy in microwave backscatter, both as a function of azimuth angle and incidence angle. This anisotropy arises as a result of i) the alignment of roughn...
