Totten Glacier Ice Shelf cavity bathymetry
This is a derived product containing two products blended together that describes the elevation of the seafloor beneath and out to approximately seaward of the Totten Glacier Ice Shelf cavity as well as the elevation of the ice bottom beneath the ice sheet immediately sounding the ice shelf cavity....
