Greenland’s icy ‘Grand Canyon’ shaped by catastrophic floods

Greenland’s icy ‘Grand Canyon’ shaped by catastrophic floods

Researchers at the University of Massachusetts Amherst and the University of Copenhagen's Center for Ice and Climate ​are proposing a new hypothesis for how Greenland's "Grand Canyon" formed: a series of catastrophic floods abruptly drained huge…

Greenland’s fastest-flowing and fastest-thinning glacier is growing again

Greenland’s fastest-flowing and fastest-thinning glacier is growing again

A new NASA research shows that Jakobshavn Glacier, which has been Greenland's fastest-flowing and fastest-thinning glacier for the last 20 years is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. The…

Unusually early melting of Greenland’s ice sheet

Unusually early melting of Greenland’s ice sheet

According to Danish Meteorological Institute (DMI), an early melt event over the Greenland ice sheet occurred this week, smashing by a month the previous records of more than 10% of the ice sheet melting. The melt was driven by warm air advected from the SW bringing…

A 3D view of the age and structure of the Greenland Ice Sheet

A 3D view of the age and structure of the Greenland Ice Sheet

Scientists using ice-penetrating radar data collected by NASA’s Operation IceBridge and earlier airborne campaigns have built the first-ever comprehensive map of layers deep inside the Greenland Ice Sheet. This new map allows scientists to determine the age of lar
