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.\nSurvey details\nSurvey Name: Kidson WA airborne gravity gradiometer survey 2017\nState/Territory: Western Australia\nDatasets Acquired: Airborne gravity gradiometer\nGeoscience Australia Project Number:\nAcquisition Start Date: July 21, 2017\nAcquisition End Date: May 3, 2018\nNumber of blocks: 2\nFlight line spacing: 2,500m\nFlight line direction: Area 1 - 180 deg/ NS; Area 2 - 270 deg/EW\nTie line spacing: 25,000m\nTie line direction: Area 1 only - 270 deg / EW\nTotal distance flown: 78,700 line kilometres\nNominal terrain clearance (above ground level): 120m\nClearance method: Drape\nAircraft type: 2 aircrafts with different Falcon AGG system installed - Cessna Grand Caravan 208B / Full spectrum Falcon system Kepler/Newton                   \nData Acquisition: CGG Aviation Australia Pty Ltd\nProject Management: Geoscience Australia\nQuality Control: Dr Mark Dransfield contracted by Geoscience Australia\nDataset Ownership: Western Australia and Geoscience Australia\nFiles included in this download\nThe 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.\nIn 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.
