... An improved knowledge of the static gravity field would help to resolve deep crustal and mantle structure and to understand plate tectonic processes, such as the structure and thermal state of ridges and trenches and the patterns of mantle convection. Additionally, a more accurately known geoid would lead to an improved mapping of the dynamic topography of the ocean, which would in turn 1 1 allow an improved determination of ocean circulation and an enhanced understanding of ocean dynamics.

... As shown in the examples above, satellite gravity measurements can provide unprecedented views of the Earth's gravity field and, given sufficient duration, its changes with time. Not only can they provide a truly global integrated view of the Earn, they have, at the same time, sufficient spatial resolution to aid in Me study of individual regions of Me Earn.
