Universtiy of Alaska studies how the melting Greenland glaciers are impacting sea levels

University of Alaska Fairbanks mathematicians and glaciologists have taken a first step toward understanding how glacier ice flowing off Greenland affects sea levels.Andy Aschwanden, Martin Truffer and Mark Fahnestock used mathematical computer models and field tests to reproduce the flow of 29 inlet glaciers fed by the Greenland ice sheet. They compared their data with data from NASA's Operation IceBridge North aerial campaign.The comparisons showed that the computer models accurately depicted current flow conditions in topographically complex Greenland.
