Version Summary
Version Summary
-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
