GNET GPS Unit in Greenland (2 of 2) (IMAGE) Ohio State University Caption This GPS unit is one of more than 50 that researchers have planted in the Greenland bedrock to measure ice loss. Researchers in the Greenland GPS Network, led by Michael Bevis at The Ohio State University, have discovered that the same hotspot that feeds Iceland's active volcanoes has been causing scientists to underestimate ice loss on Greenland.
