East Kimberley Airborne Gravity Survey 2016

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 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.<br>The data were peer reviewed by airborne gravity expert Dr Mark Dransfield contracted by Geoscience Australia.<br>The data from this survey were released by the Geological Survey of Western Australia and can be downloaded from MAGIX under reference 71156.<br><strong>Survey details</strong>Survey Name: East Kimberley Airborne Gravity Survey 2016State/Territory: Western AustraliaDatasets Acquired: Airborne gravity, Geoscience Australia Project Number: P1289Acquisition Start Date: 08 October 2016Acquisition End Date: 03 December 2016Flight line spacing: 2,500mFlight line direction: East-WestTie line spacing: 25,000mTie line direction: North-SouthTotal distance flown: 37,806 line kmNominal terrain clearance (above ground level): 160mAircraft type: Fixed wing Cessna Grand Caravan 208BData Acquisition: Sander Geophysics LimitedProject Management: Geoscience AustraliaQuality Control: Geoscience AustraliaDataset Ownership: Western Australia Department of Mines, Industry Regulation and Safety, and Geoscience Australia<br><strong>Files included in this download</strong><br><strong>1.
