BEDMAP ice-thickness database

Entry ID: GB-NERC-BAS-AEDC-00252

[ Update this Record ]

Summary

Abstract: Data describing the thickness of the Antarctic ice sheet collected on surveys undertaken over the past 50 years have been brought together into a single database. These data have allowed the compilation of a suite of seamless digital topographic models for the Antarctic continent and surrounding ocean. The suite includes grids representing: - ice-sheet ... thickness over the ice sheet and shelves, ...

Quality While the digital models have a nominal spatial resolution of 5 km, such high resolution is not strictly justified by the original data density over all parts of the ice sheet.

Use Constraints The following protocols were generally agreed by the participants of the BEDMAP consortium as providing adequate safeguards for data-collectors, whilst allowing other BEDMAP partners and, eventually, the wider community the opportunity to use BEDMAP data for research purposes. The guidelines adopted would be broadly similar to those adopted by the ADMAP consortium for magnetic anomaly data (ADMAP, ...
