Gravity Map Of Earth

The picture above is not actually a map of the topography* (height variation) of the indian ocean seafloor, as much as it looks like it. The first global gravity model based on goce satellite data from november and december 2009. The field defined this way is called the gradient vector field of the potential.

Christian hirt of curtin university in perth, western australia, and colleagues combined gravity data from satellites and topographic data to map gravity changes between latitudes 60° north and 60°. If the earth were an ideal oblate spheroid of uniform density, then the gravity measured at every point on its surface would be given precisely by a simple formula. The picture above is not actually a map of the topography* (height variation) of the indian ocean seafloor, as much as it looks like it.

But that's not actually strictly true.

Gravity anomaly map of the conterminous united states: The picture above is not actually a map of the topography* (height variation) of the indian ocean seafloor, as much as it looks like it.
