An improved solution for the gravity field shows ocean rises, as well as trench and island arcs, as mass excesses. Ocean basins, areas of recent glaciation, and the Asian portion of the Alpide belt are mass deficiencies. Most features appear interpretable as varying behavior of the lithosphere in response to asthenospheric flow.
