SUMER Antarctic Ice-shelf Buttressing, Version 1

This data set, part of the French National Research Agency’s project on Survey and Modelling of East Antarctica (SUMER), consists of high-resolution information about ice-shelf buttressing for the whole of Antarctica. Buttressing is inferred from known ice geometry and ice motion with the Elmer/Ice ice flow model. Input sources are Bedmap2, MEaSUREs surface ice velocities, and the MEaSUREs grounding-line positions.
