Scientists have discovered an ancient lakebed deep beneath the Greenland ice（图）
Scientists ancient lakebed deep beneath Greenland ice
2020/11/20
Scientists have detected what they say are the sediments of a huge ancient lakebed sealed more than a mile beneath the ice of northwest Greenland -- the first-ever discovery of such a sub-glacial feat...
Greenland Ice Sheet meltwater can flow in winter, too（图）
Greenland Ice Sheet meltwater flow winter
2020/4/17
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...
Ice is sliding toward edges of Greenland Ice Sheet（图）
Ice toward edges Greenland Ice Sheet
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...
STUDYING AND MONITORING THE GREENLAND ICE SHEET USING GIS TECHNIQUES
GIS Remote Sensing Mass Balance Accumulation Rate Global Warming Laser Altimetry Subglacial Topography DEM
2015/2/3
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...
“Probabilistic calibration of a Greenland Ice Sheet model using spatially resolved synthetic observations: toward projections of ice mass loss with uncertainties” published in Geosci. Model Dev., 7, 1933–1943, 2014
Greenland Ice Sheet spatially resolved synthetic observations
2014/12/19
Due to an oversight in the production process, the article “Probabilistic calibration of a Greenland Ice Sheet model
using spatially resolved synthetic observations: toward projections of ice mass lo...
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 ...
Greenland ice cores show industrial record of acid rain, success of U.S. Clean Air Act
Greenland ice cores industrial record of acid rain success of U.S. Clean Air Act
2014/4/16
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2014, its budg...
Holocene climate variability on millennial scales recorded in Greenland ice cores
Holocene climate variability millennial scales Greenland ice cores
2009/11/9
Climate variability is triggered by several solar and orbital cycles as well as by the intern ocean dynamics. Consequently, paleoclimate proxy records are expected to vary on very different time scale...
Testing hypotheses of the cause of peripheral thinning of the Greenland Ice Sheet:is land-terminating ice thinning at anomalously high rates?
hypotheses peripheral thinning Greenland Ice Sheet high rates
2010/2/4
Recent observations have shown that the periphery of the Greenland ice sheet (GrIS) is thinning rapidly and that this thinning is greatest around marine-terminating outlet glaciers. Several theories h...
Partitioning of melt energy and meltwater fluxes in the ablation zone of the west Greenland ice sheet
melt energy meltwater fluxes ablation zone west Greenland ice sheet
2010/2/4
We present four years (August 2003–August 2007) of surface mass balance data from the ablation zone of the west Greenland ice sheet along the 67° N latitude circle. Sonic height rangers and automatic ...
Estimation of the Greenland ice sheet surface mass balance for the 20th and 21st centuries
Estimation Greenland ice sheet surface mass balance 21st centuries
2010/2/4
Results from a regional climate simulation (1970–2006) over the Greenland ice sheet (GrIS) reveals that more than 97% of the interannual variability of the modelled Surface Mass Balance (SMB) can be e...
Reconstruction of the 1979–2006 Greenland ice sheet surface mass balance using the regional climate model MAR
Reconstruction Greenland ice sheet surface mass balance regional climate model MAR
2010/2/4
Results from a 28-year simulation (1979–2006) over the Greenland ice sheet (GrIS) reveal an increase of solid precipitation (+0.4±2.5 km3 yr−2) and run-off (+7.9±3.3 km3 yr−2) of surface m...
