IceBridge BedMachine Greenland, Version 2

This data set contains bed topography beneath the Greenland Ice Sheet based on mass conservation derived from airborne radar tracks and satellite radar. The data set also includes surface and ice thickness measurements.

There is a more recent version of these data.

Version Summary: 

Version 2 of the IceBridge BedMachine Greenland data includes improved processing of some basins and adds some Operation IceBridge 2014 data. Heights are now provided with respect to mean sea level, instead of the WGS84 ellipsoid. The geoid is included in an additional field in the data.
