Temperature, pressure, wind speed and wind direction from two automatic weather stations on the Brunt Ice Shelf that operated during 2015.

High-resolution simulations of near-surface (1.5 m) temperature and (10 m) zonal and meridional winds over the Brunt Ice Shelf in the Antarctic for the year 2015 were conducted using the atmosphere-only Met Office Unified Model by the British Antarctic Survey, Cambridge, UK. The datasets produced were necessary to place point meteorological measurements from the various automatic weather stations on the Brunt Ice Shelf into a wider spatial context by identifying spatial temperature gradients and investigating how such gradients may have affected the homogeneity of the composite Halley temperature record. The work formed part of the core science undertaken at the British Antarctic Survey.

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 https://doi.org/10.5194/tc-12-2383-2018.

This gridded dataset contains the revised bathymetry model beneath the Brunt Ice Shelf and Stancomb-Wills Glacier Tongue, Antarctica, The revised bathymetric model integrates existing direct bathymetry observations and free air gravity anomaly data to provide the best possible estimate of sub-ice shelf bathymetry. The input direct bathymetric/topographic observations, observation locations, and the input free air compilation are also available as additional separate grid files. All files are provided in NetCDF format in Antarctic Polar Stereographic (EPSG:3031) projection with a horizontal resolution of 2km. The output bathymetry model (Final_adjusted_topography.nc), input topographic observations (Topographic_value_grid.nc) and input topographic observation coverage (Topographic_observation_coverage.nc) have elevation values of metres, positive upwards. The input free air gravity anomaly grid (Brunt_FAA_compilation_grid.nc) has values of mGal. The bathymetric model was produced for the paper of Hodgson et al., (2019) investigating the past and future dynamics of the Brunt Ice Shelf. The publication reference is; Hodgson, D. A., Jordan, T.
