  • Bathymetric compilation of the Brunt sub Ice Shelf, East Antarctic Ice Sheet. The bathymetry grid was compiled from a variety of different sources including multibeam swath bathymetry collected from scientific cruises undertaken by British Antarctic Survey (BAS) and Alfred Wegener Institute (AWI). Multibeam data were supplemented with regional bathymetry from the International Bathymetric Chart of the Southern Ocean (IBSCO) and seismic data. The data is available as a 500m resolution grid using the IBSCO polar stereographic projection. For further information regarding the creation of this dataset please refer to
