Gravity data measures 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 Cape York Gravity Survey, Qld, 2009 (P200940), Bouguer 1VD grid is a first vertical derivative of the Bouguer anomaly grid for the Cape York Gravity Survey, Qld, 2009 (P200940) survey. This gravity survey was acquired under the project No. 200940 for the geological survey of QLD. The grid has a cell size of 0.0075 degrees (approximately 820m). A total of 9244 gravity stations were acquired to produce the original grid. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.
