Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. 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. This West Murchison Gravity Spherical Cap Bouguer Grid Geodetic is a complete Bouguer anomaly grid for the West Murchison Gravity Survey (P201260) survey. This gravity survey was acquired under the project No. 201260 for the geological survey of WA. The grid has a cell size of 0.00478 degrees (approximately 499m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 11816 gravity stations were acquired to produce this grid.
