<div>Sander Geophysics Limited (SGL) conducted a fixed-wing high resolution gravimetric survey in the East Kimberley area of the state of Western Australia for Geoscience Australia. A total of 37,806 line kilometres of airborne gravity data were acquired using </div><div>SGL’s airborne gravity system, Airborne Inertially Referenced Gravimeter (AIRGrav). The survey was funded by the Department of Mines, Industry Regulation and Safety (DMIRS) Western Australia, and managed by Geoscience Australia.</div><div><br></div><div>The data were peer reviewed by airborne gravity expert Dr Mark Dransfield contracted by Geoscience Australia.</div><div><br></div><div>The data from this survey were released by the Geological Survey of Western Australia and can be downloaded from MAGIX under reference 71156.</div><div><br></div><div><strong>Survey details</strong></div><div>Survey Name: East Kimberley Airborne Gravity Survey 2016</div><div>State/Territory: Western Australia</div><div>Datasets Acquired: Airborne gravity, </div><div>Geoscience Australia Project Number: P1289</div><div>Acquisition Start Date: 08 October 2016</div><div>Acquisition End Date: 03 December 2016</div><div>Flight line spacing: 2,500m</div><div>Flight line direction: East-West</div><div>Tie line spacing: 25,000m</div><div>Tie line direction: North-South</div><div>Total distance flown: 37,806 line km</div><div>Nominal terrain clearance (above ground level): 160m</div><div>Aircraft type: Fixed wing Cessna Grand Caravan 208B</div><div>Data Acquisition: Sander Geophysics Limited</div><div>Project Management: Geoscience Australia</div><div>Quality Control: Geoscience Australia</div><div>Dataset Ownership: Western Australia Department of Mines, Industry Regulation and Safety, and Geoscience Australia</div><div><br></div><div><strong>Files included in this download</strong></div><div><br></div><div><strong>1.
