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...
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...
Two Lakes Beneath the Ice in Greenland, Gone Within Weeks
Two Lakes Beneath the Ice Greenland Gone Within Weeks
2015/3/4
Researchers who are building the highest-resolution map of the Greenland Ice Sheet to date have made a surprising discovery: two lakes of meltwater that pooled beneath the ice and rapidly dr...
Melting of glacial ice will probably raise the sea level around the globe, but how fast this melting will happen is uncertain. Greenland is especially pivotal in the study of melting ice sheets and ri...
Seasonal dynamics of autotrophic and heterotrophic plankton metabolism and PCO2 in a subarctic Greenland fjord
Biological metabolic kinetics Greenland fjord
2014/10/16
We measured net planktonic community production (NCP), community respiration (CR), and gross primary
production (GPP) in September, February, and May in a subarctic Greenland fjord influenced by glac...
Study resolves discrepancy in Greenland temperatures during end of last ice age（图）
Greenland temperatures ice cores
2014/9/12
CORVALLIS, Ore. – A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming o...
A Simple Ice–Ocean Model for the Greenland Sea
East Greenland Current Greenland Sea Ice–Ocean Model
2009/1/5
A steady, coupled model of the upper ocean circulation and ice cover in a meridional channel is presented and applied to the Greenland Sea. The main ocean gyre is driven by wind stress; however a nonz...
A Simple Steady-State Coupled Ice-Ocean Model, with Application to the Greenland-Norwegian Sea
A Simple Steady-State Greenland-Norwegian Sea Ice-Ocean Model
2008/12/30
A thermodynamic reduced-gravity ocean model forced by the steady-state surface wind stress and a Haney-type heat flux was used to determine the climatological ice-edge position, ice thickness, ocean c...
Numerical Investigation of the Circulation In the Greenland and Norwegian Seas
Numerical Investigation Norwegian Seas Greenland
2008/12/23
An ocean general circulation model is used to investigate the circulation in the Greenland and Norwegian seas. The primitive equations are solved on 12 levels with a horizontal grid-point distance of ...

2008/11/24
Quasi-meridional flux estimates for volume, heat, and freshwater, with computed errors, in the region of the subpolar gyre of the North Atlantic between Cape Farewell and Ireland between 53° and 60°N ...
An Investigation of the Dynamics of the East Greenland Current in Fram Strait Based on a Simple Analytical Model
East Greenland Current Fram Strait Simple Analytical Model
2008/7/21
The East Greenland Current (EGC) in Fram Strait is examined in summer, based on the hydrographic data from the MIZEX 84 experiment, and its dynamics is further analyzed using a simple analytical model...
Is Bottom Boundary Layer Mixing Slowly Ventilating Greenland Sea Deep Water
Bottom Boundary Layer Greenland Sea Deep Water
2008/6/26
Bottom water temperatures in the central Greenland Sea have been increasing for the last two decades. The warming is most likely related to the absence of deep convective mixing, which cools and fresh...
