Lythe, M. B., D. G. Vaughan, and the BEDMAP Consortium. 2000. BEDMAP - bed topography of the Antarctic. Cambridge, United Kingdom: British Antarctic Survey. Digital Media. Available at http://www.antarctica.ac.uk//bas_research/data/access/bedmap/. Accessed 28 June 2008. Background: The BEDMAP project was conceived as an attempt to rationalise the coverage of ice thickness measurements over Antarctica, collect the data together and produce a new topographic model of the bed of the Antarctic Ice Sheet, to provide a new basis for all aspects of Antarctic geoscience. Includes the entire area south of 60 degrees south latitude. Resolution: 5 km. Time Period: 1951-1999. Sources: ground-based and airborne surveys, primarily from radar and seismic sounding as well as gravimetric measurements. Elevations are relative to the OSU91A geoid. Lythe, M. B., D. G.
