Gravity Gradiometry

Gravity gradiometry is used by oil as well as mineral prospectors to measure the density from the subsurface, effectively the rate of modify of rock components. From this information you’ll be able to build a picture of subsurface anomalies which will then be used to more accurately concentrate on oil, gas and calcium deposits. It is also used to image water column density, when locating submerged objects, as well as determining water interesting depth.
