We present extensive new bathymetric compilation over Anvers-Hugo Trough, Perrier Trough and Palmer Deep, here defined by the following bounding box: 66.15 to 64.0 W, 65.25 to 63.6 S. This bathymetry grid was compiled from a variety of different data sources including multibeam swath bathymetry collected from scientific cruises undertaken by British Antarctic Survey (BAS), United Kingdom Hydrographic Office, or acquired during RVIB Nathaniel B. Palmer, HMS Protector and RV Maurice Ewing expeditions. The data is available as a 30m resolution grid either in a NetCDF format using WGS84 coordinate system (EPSG: 4326) or in an ESRI ASCII interchange raster format in standard Antarctic polar stereographic coordinates (EPSG 3031). The grid have been created using the MB-system mbgrid program. For further information regarding the creation of this dataset please refer to the associated article and the supplementary information.
We present here Topographic Parametric Sonar (TOPAS) acoustic sub-bottom profiler data acquired on RRS James Clark Ross JR298 cruise in 2015. Data are provided in SEG-Y format. This project was funded by UK Natural Environment Research Council Grant NE/J006548/1: Depositional patterns and records in sediment drifts off the Antarctic Peninsula and West Antarctica
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.
