The MEaSUREs BedMachine Antarctica, Version 3 data set, accessible from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), is now available. Additional ice thickness data have been used, thinning rates have been updated, and the International Bathymetric Chart of the Southern Ocean (IBCSO) version 2 has been used for ocean bathymetry. A new parameter, dataid, has also been added to help with identifying the data source used for each cell.
This data set is part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program. It contains a bed topography/bathymetry map of Antarctica based on mass conservation, streamline diffusion, and other methods.
