Since the late 1970’s, he’s been studying the ice sheets in Antarctica using an airborne [-----2-----]. He told EarthSky that certain ice sheets are more susceptible than others to melting.

Since 2008, Blankenship has been [-----4-----] the East Antarctic ice sheet – more than a third of which is below sea level. Blankenship estimates that the ice within this ice sheet has the potential to raise global sea level by 60 meters, or 200 feet.
