Holocene thinning of the Greenland ice sheet

Nature, 2009
On entering an era of global warming, the stability of the Greenland ice sheet (GIS) is an important concern, especially in the light of new evidence of rapidly changing flow and melt conditions at the GIS margins. Studying the response of the GIS to past climatic change may help to advance our understanding of GIS dynamics. The previous interpretation

Growth of Greenland Ice Sheet: Measurement

Science, 1989
Measurements of ice-sheet elevation change by satellite altimetry show that the Greenland surface elevation south of 72° north latitude is increasing. The vertical velocity of the surface is 0.20 ± 0.06 meters per year from measured changes in surface elevations at 5906 intersections between Geosat paths in 1985 and Seasat in 1978, and 0.28 ± 0.02 ...

Greenland ice sheet mass balance: a review

Reports on Progress in Physics, 2015
Over the past quarter of a century the Arctic has warmed more than any other region on Earth, causing a profound impact on the Greenland ice sheet (GrIS) and its contribution to the rise in global sea level. The loss of ice can be partitioned into processes related to surface mass balance and to ice discharge, which are forced by internal or external ...

Greenland ice sheet hydrology

Progress in Physical Geography: Earth and Environment, 2013
Understanding Greenland ice sheet (GrIS) hydrology is essential for evaluating response of ice dynamics to a warming climate and future contributions to global sea level rise. Recently observed increases in temperature and melt extent over the GrIS have prompted numerous remote sensing, modeling, and field studies gauging the response of the ice sheet

Growth of Greenland Ice Sheet: Interpretation

Science, 1989
An observed 0.23 m/year thickening of the Greenland ice sheet indicates a 25% to 45% excess ice accumulation over the amount required to balance the outward ice flow. The implied global sea-level depletion is 0.2 to 0.4 mm/year, depending on whether the thickening is only recent (5 to 10 years) or longer term (< 100 years).

Past Temperatures Directly from the Greenland Ice Sheet

Science, 1998
A Monte Carlo inverse method has been used on the temperature profiles measured down through the Greenland Ice Core Project (GRIP) borehole, at the summit of the Greenland Ice Sheet, and the Dye 3 borehole 865 kilometers farther south. The result is a 50,000-year-long temperature history at GRIP and a 7000-year history at Dye 3.

The Greenland Ice Sheet Reacts

Science, 2000
The Greenland Ice Sheet holds a substantial part of Earth's fresh water, and melting of the sheet contributes to sea level rise. [Dahl-Jensen][1] discusses the reports by [ Krabill et al .][2] and [ Thomas et al .][3], which shed light on short- and long-term surface elevation changes of the ice sheet.
