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

-Generated ensemble of bed topography maps using ICESat-2 time series and used the median depth instead of a single estimate for some glaciers
-Used ice thickness estimates from IceBoost for periphery glaciers (Maffezzoli et al., 2025)
-Added a new field 'RGI' that indicates which pixel belongs to a glacier in the Randolph Glacier Inventory
-Added bathymetry data from the Danish Hydrographic Office
-Updated bathymetry of Petermann based on Ciraci et al. (2023) gravity inversion
