Abstract: The article presents a study that focuses on collecting independent regional cavity geometry representation of sub-ice shelf circulation and freezing/melting rates and turn them into a global data set using S-2004 global 1-min bathymetry and an improved version of the bed topography mapping (BEDMAP). It relates that existing global cavity geometry data sets contain inconsistencies and inaccuracies. However, local or regional simulations were able to use more detailed data sets.
