    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 Tennant Creek-Mt Isa (TISA) Gravity Surveys, Tennant East (CSCBA grid) is a complete spherical cap Bouguer anomaly grid for the Tennant Creek-Mt Isa (TISA) Gravity Surveys, South West McArthur Barkley, Northern Territory, 2019. This gravity survey was acquired under the project No. 201901 for the geological survey of NT, QLD. The grid has a cell size of 0.00464 degrees (approximately 500m).
