Blackstone Combined Bouguer Anomaly geodetic

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 Blackstone Combined Bouguer Anomaly geodetic is a complete Bouguer anomaly grid for the Blackstone WA Gravity Survey (P200663). This gravity survey was acquired under the project No. 200663 for the geological survey of WA. The grid has a cell size of 0.00556 degrees (approximately 585m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 309 gravity stations were acquired to produce this grid.

Statement

This Blackstone Combined Bouguer Anomaly geodetic is a simple Bouguer anomaly grid for the Blackstone WA Gravity Survey (P200663). This gravity survey was acquired under the project No. 200663 for the geological survey of WA. The grid has a cell size of 0.00556 degrees (approximately 585m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 309 gravity stations were acquired to produce this grid. The Bouguer gravity anomalies were calculated by applying a Bouguer correction with a density of 2670 kg per cubic meter to the point data of Blackstone WA Gravity Survey (P200663). The data were then gridded using a gridding technique provided by the INTREPID Geophysics software package. 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).
