British Antarctic Survey, 2013. Bedmap2 - Bed topography of Antarctica, 1:10,000,000 scale map. BAS
Thematic Map Series, Sheets 1A and 1B, Edition 1. Cambridge, British Antarctic Survey.
Abstract:
This geophysical and glaciological map shows the surface of the bed beneath the Antarctic Ice Sheet. The
surface elevation was created using data from a variety of sources, including many substantial surveys
completed since the original Bedmap compilation (Bedmap1) in 2001. In particular, the Bedmap2 ice thickness
grid is made from 25 million measurements, over two orders of magnitude more than were used in Bedmap1. In
most parts of Antarctica the subglacial landscape is visible in much greater detail than was previously
available and the improved data coverage has in many areas revealed the full scale of mountain ranges,
valleys, basins and troughs, only fragments of which were previously indicated in local surveys.
The map shows the elevation data with key place names and the coastline and grounding line indicated. The map
also includes cross-sectional profiles through East and West Antarctica and separate panels showing the
geographical distribution of primary survey data and reliability of the bed surface. On the reverse side is
an oblique view of the continent with information and statistics given regarding key areas of interest.
Purpose:
This map showcases Bedmap2. The geophysical and glaciological map shows the surface of the bed beneath the
Antarctic Ice Sheet.
