Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface.

The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
