Introduction and Aims
- An adequate data set describing bed elevation over the continent and continental shelf does not exist. No one institute has a complete knowledge of which areas have been surveyed and which are lacking in even reconnaissance level data.
- The 1983 SPRI Folio 'The Bedrock Surface of Antarctica' remains the most widely adopted map of bed elevation.
- An outstanding step forward for Antarctic science would be achieved in many disciplines by the production of a new topographic model for Antarctica.

(i) to rationalise the coverage of ice thickness observations over Antarctica
(ii) assemble these data, undertake quality assurance and validation
(iii) produce a digital topographic model of ice thickness and bed elevation
(iv) establish long term database, provide access to researchers
