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. This p200880 Central Arunta Gravity spherical cap Bouguer Vert Deriv geodetic is the first vertical derivative of the spheical cap Bouguer anomaly grid for the Central Arunta Gravity Survey, NT (P200880). This gravity survey was acquired under the project No. 200880 for the geological survey of NT. The grid has a cell size of 0.0037 degrees (approximately 395m). A total of 11829 gravity stations at variable spacing between 500m and 4000m were acquired to produce this grid. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
