Brief description
BEDMAP1 is a dataset describing the thickness of the Antarctic ice sheet collected on surveys undertaken over the past 50 years have been brought together into a single database. These data have allowed the compilation of a suite of seamless digital topographic models for the Antarctic continent and surrounding ocean. The suite includes grids representing;-ice-sheet thickness over the ice sheet and shelves
-water-column thickness beneath the floating ice shelves
-bed elevation beneath the grounded ice sheet
-bathymetry to 60°S including the areas beneath the ice shelves.
The data have a 5 km resolution. The original data were in ArcInfo grid ascii format and they have been processed by TPAC using GDAL and NCO to translate them to netcdf format.
Data time period: 31 12 1949 to 31 12 2000
