![Gravity anomalies covering the Southern Ocean are shown here in false-color relief. Amplitudes range between -30 mGal (magenta) to +30 mGal (red). This image has been normalized to remove variation due to differences in latitude](/Images/godic/202501/27/Southern_ocean_gravity_hg3035.png")
Gravimetry is the measurement of the strength of a gravitational field. Gravimetry may be used when either the magnitude of gravitational field or the properties of matter responsible for its creation are of interest.
