Version Summary

Changes to this version include:
- additional thickness data to constrain the bed topography under grounded ice
- new multi-beam ocean bathymetry data, as well as gravity inversions, integrated in the Amundsen Sea embayment
- an error in geoid height was corrected for the IBCSO bathymetry

Overview

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, contains a bed topography/bathymetry map of Antarctica based on mass conservation, streamline diffusion, and other methods. The data set also includes ice thickness, surface elevation, an ice/ocean/land mask, ice thickness estimation errors, and a map showing where each method was utilized.
