Greenland Basal Topography

British Antarctic Survey, 2017. Greenland Basal Topography, 1:3,500,000 scale map. BAS Thematic Map Series, Sheets 2A and 2B, Edition 1. Cambridge, British Antarctic Survey.

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 British Antarctic Survey and Bristol University, based on 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 place names, coastline and the 0 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.
