41– Gravity gradiometry is the study and measurement of variations in the acceleration due to gravity gradient is the spatial rate of change of gravitational acceleration. Gravity gradiometry is used by oil and mineral prospectors to measure the density of the subsurface, effectively by measuring the rate of change of gravitational acceleration (or jerk) due to underlying rock properties.
