NASA Mission Checks Health of Greenland's Ice Sheet and Glaciers

A NASA-led research team has returned from Greenland after an annual three-week mission to check the health of its glaciers and ice sheet. About 82 percent of Greenland is made up of a giant ice sheet. During the Arctic Ice Mapping Project, researchers measured critical areas of the island's ice sheet as well as its glaciers and monitored changes that may be connected to global climate change.

Past measurements from the team have shown that areas of ice along the Greenland coast have been thinning while inland areas have thickened. However, when these changes are taken as a whole, Greenland has experienced a significant loss of ice.
