Improved data sets of ice shelf draft and underlying bathymetry 7, 5509–5540, 2013 are important for assessing ocean–ice interactions and modeling ice response to cli- 5 mate change. The long, narrow Abbot Ice Shelf south of Thurston Island produces Tectonic and large volumes of meltwater but is in overall mass balance unlike other ice shelves in oceanographic the region that are losing mass.
