BEDMAP1 - Ice thickness, bed and surface elevation for Antarctica - gridding products ...
We present here BEDMAP1 (2000-2001), a suite of gridded products describing surface elevation, ice-thickness and the sea floor and subglacial bed elevation of the Antarctic south of 60deg S. The suite includes grids representing: - ice-sheet thickness over the ice sheet and shelves, - bed elevation...
