CGG Aviation (now Xcalibur Multiphysics) collected airborne gravity data in the Kidson area covering parts of the Gibson and Great Sandy Deserts in central Western Australia as part of a collaborative project between Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA). The aim of the project was to collect airborne gravity gradiometry data in the region at 2500 m wavelength resolution to help characterise key undercover geological elements of the region. The survey consisted of a Main block and an Extension block. Data were acquired from North/South flight lines (Main block) and East-West flight lines (Extension block) with an average target ground clearance of 120m. Tie lines at 25,000m line spacing were flown only for the Main block. A total of 78,700 line kilometres of data were collected during the survey.

Data Acquisition: CGG Aviation Australia Pty Ltd Project Management: Geoscience Australia Quality Control: Dr Mark Dransfield contracted by Geoscience Australia Dataset Ownership: Western Australia and Geoscience Australia Files included in this download The original agreement with CGG Aviation Australia Pty Ltd (CGG) stated that gradient point located data was available for purchase on non-exclusive terms from CGG until 30 June 2027, after which date the gradient data would be made public. In July 2021, the terms of the agreement changed after Xcalibur Multiphysics acquired CGG Aviation Pty Ltd. Xcalibur authorised the release of the gradient data. A new final dataset and report was generated by Xcalibur and delivered to Geoscience Australia. This data release contains the gradient point located data. 1. Point-located Data / line data ASEG-GDF2 and Geosoft GDB format with accompanying description and definition files. The sample frequency is 8Hz. 2. Grids Datum: GDA2020 Projection: MGA 51 Grid cell size: 500m Formats: Geosoft GRD and ERMapper (.ers) with accompanying description files. 3. Reports • Final survey logistic report delivered to Geoscience Australia by the survey contractor. • Kidson QC report from Dr Mark Dransfield The data from this Kidson airborne gravity gradiometry survey has been released and can be downloaded from the Geological Survey of Western Australia’s MAGIX platform at https://magix.dmirs.wa.gov.au and GeoVIEW.WA web mapping application at https://geoview.dmp.wa.gov.au/GeoView under reference number 71234.
