Greenland Basal Topography Map

This double-sided geophysical and glaciological map shows the basal topography of Greenland and surrounding seabed. The topography of the subglacial landscape under the Greenland Icesheet was modelled using a mixture of radio echo-sounding and a glaciological model (BEDMACHINE 2) and is presented in a similar colour scheme to the Antarctic BEDMAP2. The map is a result of a collaboration between BAS and Bristol University, based on recently released data from a joint project between Bristol University and the University of Irvine California. Side 1 shows a detailed map, in plan view, and includes important names, coastline and the zero metre contour. Side 2 presents a 3D view of the dataset, highlighting some of the important and interesting features and gives further details of how the surface was constructed.
