2021-6-30  Gravity. Gravity surveys measure the acceleration due to gravity. Typically this is around 9.8 ms-2 at the surface of the Earth, however a gravity survey will measure variations in this value to (approximately) eight decimal places. Variations in acceleration give us information relating to the density of subsurface material.
