    The GeoMAP (v.2022-08) continent-wide detailed geological dataset of Antarctica (2023)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: A dataset describing exposed bedrock and surficial geology of Antarctica constructed by the GeoMAP Action Group of SCAR (The Scientific Committee on Antarctic Research) and GNS Science, New Zealand. Legacy geological map data have been captured into a geographic information system (GIS), refining its spatial reliability, harmonising classification, then improving representation of glacial sequences and geomorphology. A total 99,080 polygons have been unified for depicting geology at 1:250,000 scale, but locally there are some areas with higher spatial precision. Geological definition in GeoMAP v.2022-08 is founded on a mixed chronostratigraphic- and lithostratigraphic-based classification. Description of rock and moraine polygons employs international GeoSciML data protocols to provide attribute-rich and queriable data; including bibliographic links to 589 source maps and scientific literature. Data are provided under CC-BY License as zipped ArcGIS geodatabase, QGIS geopackage or GoogleEarth kmz files. GeoMAP is the first detailed geological dataset covering all of Antarctica. GeoMAP depicts 'known geology' of rock exposures rather than 'interpreted' sub-ice features and is suitable for continent-wide perspectives and cross-discipline interrogation.

    Basement topography and sediment thickness beneath Antarctica's Ross Ice Shelf imaged with airborne magnetic data (2022)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: Depth to the magnetic basement beneath Antarctica's Ross Ice Shelf was determined from Werner deconvolution of ROSETTA-Ice airborne magnetic data. This process was constrained by offshore seismic data which was tied to the Ross Ice Shelf with Operation Ice Bridge IceBridge airborne magnetic data. Using a sub-ice shelf bathymetry model, we calculated the thickness of non-magnetic cover sediments above the basement. This dataset contains NetCDF grids, for both Ross Ice Shelf and Ross Embayment extents, of basement elevations and sediment thicknesses, as well as their accompanied upper and lower uncertainties. Also included are profiles of all ROSETTA-Ice flight lines, showing Werner deconvolution solutions and the resulting magnetic basement. Basement solutions before gridding are available in a text file. Code for the creation and processing of all the data here is available at Github, through the following link: https://doi.org/10.5281/zenodo.6499863.
