Description

This data set contains a bed topography and bathymetry map of Greenland based on mass conservation, multi-beam data, and other techniques. It also includes surface elevation and ice thickness data, as well as an ice/ocean/land mask.

Version Description

In Version 7, the bed topography in the interior of the ice sheet is now mapped using Ice Flow Perturbation Analysis (see https://doi.org/10.1029/2026GL122028).
