Bowen Surat Gravity Complete Bouguer Anomaly 1VD
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 Bowen Surat Gravity Complete Bouguer Anomaly 1VD is a complete Bouguer anomaly grid for the Bowen Surat (P200540). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid. This gravity survey was acquired under the project No. 200540 for the geological survey of QLD. The grid has a cell size of 0.00764 degrees (approximately 800m). A total of 4977 gravity stations were acquired to produce this grid.

- Statement
-
This Bowen Surat Gravity Complete Bouguer Anomaly 1VD is a first vertical derivative of the complete Bouguer anomaly grid for the Bowen Surat (P200540). This gravity survey was acquired under the project No. 200540 for the geological survey of QLD. The grid has a cell size of 0.00764 degrees (approximately 800m). A total of 4977 gravity stations at 4000m spacing were acquired to produce this grid. The complete Bouguer gravity anomalies were calculated by applying terrain correction (Bullard C - which accounts for the undulations of the surrounding topography) to the spherical cap Bouguer anomaly point data of Bowen Surat (P200540). These terrain corrections were calculated using software from INTREPID Geophysics. The Intrepid algorithm utilises concentric rings subdivided into cells (Direen, 2001) to calculate the terrain correction. The data were then gridded using a gridding technique provided by the INTREPID Geophysics software package. A Fast Fourier Transform (FFT) process was applied to the complete infinite slab Bouguer gravity grid of the survey area to calculate the first vertical derivative grid. The processed data are checked by GA geophysicists using standard methods for assessing quality to ensure that the final data are fit-for-purpose. Details of the specifications of individual surveys held in the Australian National Gravity Database (ANGD) can be found in the Second Edition of the Index of Gravity Surveys (Wynne and Bacchin, 2009).
