North Perth Gingin Brook Gravity Complete Spherical Cap Bouger Anomaly 267GU First Vertical Derivative Geodetic p201360.ers

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 North Perth Gingin Brook Gravity Complete Spherical Cap Bouger Anomaly 267GU First Vertical Derivative Geodetic p201360.ers is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the North Perth Gingin Brook Gravity Survey, 2013 (P201360). This gravity survey was acquired under the project No. 201360 for the geological survey of WA. The grid has a cell size of 0.00363 degrees (approximately 374m). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid. A total of 1236 gravity stations at 1500m spacing were acquired to produce this grid.
