Version 4 of MEaSUREs BedMachine Antarctica is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains a bed topography and bathymetry map of Antarctica deduced by subtracting the ice thickness from the surface elevation taken from the Reference Elevation Model of Antarctica (REMA). This version of the dataset includes new bathymetry data and ice thickness estimate inputs. Additionally, a new glacier mask has been added. This data set is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
