P1293 Kidson WA airborne gravity gradiometer survey 2017
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.

<b>Files included in this download</b>
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.

- Purpose
-
High-resolution gravity on regional/district scales is an important component of mineral and energy integrated pre-competitive approach to data collection and information to support new and ongoing industry exploration investment in Australia's resources. Such data is also invaluable for vertical positioning accuracy with industry and government agencies requiring vertical height surfaces to within 10 cm for advanced (often autonomous) operations, productivity efficiency, and safety.

<div>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 data was collected at 2.5 km wavelength resolution to help characterise key undercover geological elements of the region. The survey consisted of two areas. A total of 78,700 line kilometres of data were collected during the survey. During the survey, two aircraft were used. Each aircraft had a different Falcon Airborne Gravity Gradiometer (AGG) system installed: Kepler Digital and Newton Analog. An sGrav was used on the survey to improve the long wavelength gravity signal, but it failed during the acquisition. </div><div> </div><div>Data processing was conducted by Xcalibur Multiphysics. This includes spectral analysis, signal resolution, noise analysis, noise reduction, tensor transformation, sGrav processing and data conforming. During the processing, the portions of the survey area with no sGrav data were filled with regional gravity data taken from the 2019 Australian National Gravity Grid (Lane et al, 2020). The final data were peer reviewed by AGG expert Dr Mark Dransfield contracted by Geoscience Australia. </div><div> </div><div>Reference: </div><div>Lane, R.J.L., Wynne, P.E., Poudjom Djomani, Y., Stratford, W.R., Barretto, J.A., Caratori Tontini, F. 2020. 2019 Australian National Gravity Grids: Free Air Anomaly, Complete Bouguer Anomaly, De-trended Global Isostatic Residual, 400 m cell size (includes Point Located Data).
