Airborne 3D basal DEM and ice thickness map of Pine Island Glacier

During NASA's Operation Ice Bridge a gridded survey was flown over Pine Island Glacier (PIG). This survey was a finer grid than previously flown over this area. The data collected confirm that the majority of the ice at the bottom of PIG is below sea level which could be a major cause in the speed-up of the ice flow in that area. These data can be used in flow rate calculations and to the mass balance in that area.
