DOUBLE‐TRACK PROFILING WITH THE GRAVITY METER

Abstract

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.
