A hypothetical ocean model called a "geoid" is helping us uncover the hidden gravity points underneath our landmasses; including the ever mysterious Antarctica.

Earth tectonics as seen by GOCE - Enhanced satellite gravity gradient imaging
" This is particularly apparent for the cratonic regions of the Earth. The comparisons demonstrate that the combination of seismological, and satellite gravity gradient imaging has significant potential to enhance our knowledge of Earth’s structure. In remote frontiers like the Antarctic continent, where even basic knowledge of lithospheric scale features remains incomplete, the curvature images help unveil the heterogeneity in lithospheric structure, e.g. between the composite East Antarctic Craton and the West Antarctic Rift System."

The Gravity Field and Steady-State Ocean Circulation Explorer
"It was launched on 17 March 2009. Owing to its sleek shape, GOCE is often cited as one of ESA's most elegant space probes. The mission ended on 11 November 2013 after a planned destructive re-entry into the atmosphere."

Beneath Antarctica’s Ice Is a Graveyard of Dead Continents
"The eastern section of Antarctica is buried beneath a thick ice sheet. Some scientists simply assumed that under that cold mass there was nothing more than a “frozen tectonic block,” a somewhat homogeneous mass that distinguished it from the mixed up geologies of other continents."
