This technique, providing, simultaneously, gravity values and horizontal gravity gradients, is briefly discussed because of its possible advantage in marine exploration using the underwater gravity meter. Operating these remote-control meters at greater depth is rather cumbersome and costly if compared to surveys at the ground surface (Dobrin, 1960). However, a profile of average horizontal gradients, in addition to a regular gravity profile, would indicate positive or negative anomalies located away from the profile itself, and would help avoid gravity stations with insignificant interpretative value.
