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. The seafloor was inferred by inverting airborne gravity observations; the terrain beneath grounded ice was observed with airborne ice sounding radar measurements. The two products were blended along the grounding line observed with satellite observations [Rignot, E., Mouginot, J. and Scheuchl, B. Antarctic grounding line mapping from differential satellite radar interferometry. Geophys. Res. Lett. 38, L10504 (2011)].
We have provided a text file that contains three columns that may be used to produce a gridded bathymetry of the Totten Glacier Ice Shelf and surrounding area with a cell size of 1-km. The first two columns contain grid coordinates using the Polar Stereographic projection based on WGS84 with true scale at 71 degrees S. The third column contains the vertical coordinate representing the seafloor beneath and the ice-bottom elevation around the Totten Glacier Ice Shelf cavity. The center of the region is located near 115E and 67S and spans an area about 217 km by 131 km.
