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 is on track to lose ice faster this century than in any other over the past 12,000 years(图)
Greenland lose ice faster century past 12,000 years
2020/10/10
Greenland's rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes.The U.S. National Science Foundation-supported researc...
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...
New research shows an iceless Greenland may be in the future(图)
iceless Greenland future greenhouse gas ice sheet
2019/10/28
New research shows that an iceless Greenland may be in the future. If worldwide greenhouse gas emissions remain on their current trajectory, Greenland may be ice-free by the year 3000. By the end of t...
Research shows ice sheets as large as Greenland’s melted fast in a warming climate(图)
ice sheets as large as Greenland’s melted fast warming climate
2017/11/24
New research published in Science shows that climate warming reduced the mass of the Cordilleran Ice Sheet by half in as little as 500 years, indicating the Greenland Ice Sheet could have a similar fa...
New maps of Greenland’s coastal seafloor and bedrock beneath its massive ice sheet show that two to four times as many coastal glaciers are at risk of accelerated melting as had previously been though...
The National Science Foundation (NSF) is accepting proposals from media professionals to visit Greenland and report on scientific research in the Arctic supported by NSF's Office of Polar Programs.
MASS BALANCE CHANGES AND ICE DYNAMICS OF GREENLAND AND ANTARCTIC ICE SHEETS FROM LASER ALTIMETRY
Laser Atimetry Surface Elevation Changes Greenland Antarctica Ice Sheet Mass Balance Sea-Level Rise
2016/11/30
During the past few decades the Greenland and Antarctic ice sheets have lost ice at accelerating rates, caused by increasing surface temperature. The melting of the two big ice sheets has a big impact...
IDENTIFICATION OF A ROBUST LICHEN INDEX FOR THE DECONVOLUTION OF LICHEN AND ROCK MIXTURES USING PATTERN SEARCH ALGORITHM (CASE STUDY:GREENLAND)
Hyperspectral Remote Sensing Mineral Exploration Geological Mapping Spectral Mixture Analysis Spectrometry Lichen
2016/11/24
Lichens are the dominant autotrophs of polar and subpolar ecosystems commonly encrust the rock outcrops. Spectral mixing of lichens and bare rock can shift diagnostic spectral features of materials of...
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...
USING REMOTE SENSING AND RPAS FOR ARCHAEOLOGY AND MONITORING IN WESTERN GREENLAND
Aerial Photogrammetry RPAS Glaciology InSAR Greenland
2016/7/5
Since 2002, German low-cost scientific expeditions to Greenland have been performed. The objective was a geodetic survey and glaciology with GNSS technology – mainly the measurement of glacier profile...
Fecal steroids of the coprolite of a Greenland Eskimo mummy, AD 1475: a clue to dietary sterol intake
Cholesterol plant sterols fecal bile acids
2016/6/14
Sterols in feces reflect sterols in the diet. In previous
analyses of the fecal steroids in 1000–2000-y-old Native
American coprolites found in the dry caves of Nevada, we
showed that the sterol nu...
A history of snowfall on Greenland,hidden in ancient leaf waxes
history of snowfall Greenland ancient leaf waxes
2016/5/31
The history of Greenland’s snowfall is chronicled in an unlikely place: the remains of aquatic plants that died long ago, collecting at the bottom of lakes in horizontal layers that document the passi...
Researchers from MIT, Princeton University, and elsewhere have developed a new technique to monitor the seasonal changes in Greenland’s ice sheet, using seismic vibrations generated by crashing ocean ...
