“A consistent data set of Antarctic ice sheet topography, cavity geometry, and global bathymetry,” co-authored by Eugene Domack, the Joel W. Johnson Family Professor of Geosciences, was published on Dec. 22, in Earth System Science Data - The Data Publishing Journal.
Sub-ice shelf circulation and freezing/melting rates in ocean general circulation models depend critically on an accurate and consistent representation of cavity geometry. Existing global or pan-Antarctic topography data sets have turned out to contain various inconsistencies and inaccuracies. The paper includes a compilation of independent regional surveys and maps into a global data set for an area that roughly coincides with the Antarctic continental shelf.
