MEaSUREs BedMachine Antarctica V004
Listed in NASA Earthdata CMR
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains a bed topography and bathymetry map of Antarctica.
Description
Bed topography is deduced by subtracting ice thickness from the surface elevation; using Ice Flow Perturbation Analysis (IFPA); and by other methods. Surface elevations are obtained from the Reference Elevation Model of Antarctica (REMA) and high-resolution satellite maps.
