West Arunta Complete Spherical Cap Bouguer 1VD Geodetic

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 Arunta Complete Spherical Cap Bouguer 1VD Geodetic is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the West Arunta Gravity Survey, 2010 (P201080). This gravity survey was acquired under the project No. 201080 for the geological survey of NT. The grid has a cell size of 0.00747 degrees (approximately 799m). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid. A total of 12428 gravity stations at a spacing between 1000m and 4000m were acquired to produce this grid.
