Bedmap (2001 – present): ice bed, surface and thickness datasets for Antarctica

Start date
1 January, 2001

Bedmap is a collaborative community project with the aim to produce a new map and datasets of Antarctic ice thickness and bed topography for the international glaciology and geophysical community, using a variety of data (including ice-thickness, bathymetry, surface altitude and grounding lines).

The Bedmap Portal (bedmap.scar.org) provides a direct access to the ice thickness, bed and surface elevation datasets. An associated Geophysics Book gives the list of data available and provides interactive codes to help you use the data with Python.
