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 NTGS Daly Basin Gravity P201680 Spherical Cap Bouguer Anomaly 267G 1VD is the first vertical derivative of the spheical cap Bouguer anomaly grid for the NTGS Daly Basin Gravity Survey 2016 (P201680). This gravity survey was acquired under the project No. 201680 for the geological survey of NT. The grid has a cell size of 0.00732 degrees (approximately 800m). A total of 2271 gravity stations at variable spacing between 4000m and 1000m 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.
