Latest Greenland ice sheet Stories
GREENBELT, Md., March 20, 2015 /PRNewswire-USNewswire/ -- NASA's Operation IceBridge, an airborne survey of polar ice, successfully completed its first Greenland research flight of 2015 on March
As the massive ice sheet that once covered much of North America began to melt, icebergs and meltwater would have regularly reached South Carolina and even Florida, according to new research published in the current advance online edition of the journal Nature Geosciences.
Thanks in part to support from NASA and the National Science Foundation, scientists have produced the first-ever detailed maps of bedrock beneath glaciers in Greenland and Antarctica.
Prevailing models from the melting of the Greenland ice sheet have made the calculation that the ice sheet sits atop hard bedrock. A new study from a team of British and American scientists has thrown out that assumption, however.
Data from the European Space Agency's CryoSat-2 spacecraft has been used to map elevation and elevation changes in both Greenland and Antarctica by a team of researchers from the Alfred Wegener Institute in Germany.
A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters.
Ice loss from the Greenland Ice Sheet has increased four-fold over the past four decades, and scientists now report that oceans play a vital role in how quickly the ice sheet will melt and how much total mass will be lost.
Newly discovered massive blocks of ice located underneath the ice of Greenland could help scientists learn more about the behavior of ice sheets and how they will respond to global warming, according to research appearing in the latest edition of Nature Geoscience.
IceBridge's campaign began on Mar. 10 when NASA's P-3 research aircraft left Wallops for Thule. For the first part of the campaign, researchers studied Arctic sea ice from Thule and Fairbanks, Alaska.
In 1889 and 2012, there was large-scale melting of the Greenland ice sheet, and a new study reveals that rising temperatures and ash from Northern Hemisphere forest fires combined to cause the ice melting events.
