A global gravimetric view of the seafloor thus becomes accessible through satellite derived gravity data haxby et al. Data from the smith and sandwell global topography smith and sandwell 1977 are a combination of shipboard depth soundings and estimated depths based on gravity measurements to produce a gridded representation of seafloor topography for all ice free ocean areas within 72 w latitude.

Global maps constructed using satellite derived gravity data in contrast are limited in the size of features they can resolve. In 2008 we generated a version of satellite gravity we termed the trident solution by stacking three independently derived solutions of free air gravity from the geosat and ers 1 satellites.
