P1291A North East Canning Airborne Gravity Survey 2017

An airborne gravity survey was conducted over the North East Canning area in the Kimberley region of Western Australia as a part of the Tanami-NE Canning Western Australia Airborne Gravity Survey 2017. The survey was part of a collaborative research project between Geoscience Australia (GA) and the Geological Survey of Western Australia. Gravity data was collected at 5 km wavelength resolution with the purpose to help characterise key undercover geological elements of the region. The survey was conducted by Thomson Aviation Pty Ltd with a GT-2A gravimeter and managed by Geoscience Australia. A total of 23,953.65 line km of data were acquired over an area of 53,346 km².<strong>Survey details</strong>Survey Name: Tanami North East Canning Airborne gravity surveyState/Territory: Western Australia (WA)Datasets Acquired: Airborne gravity Geoscience Australia Project Number: P1291A Acquisition Start Date: 17 August 2017 Acquisition End Date: 15 November 2017 Flight line spacing: 2.5 km Flight line direction: 180deg / NS Tie line spacing: 25km Tie line direction: 270 deg / EWTotal line kilometers: 23,953.65 Nominal terrain clearance (above ground level): 710 m Aircraft model: GippsAero GA-8 AirvanData Acquisition: Thomson Aviation Pty Ltd Project Management: Geoscience Australia Quality Control: CMG Operations Pty Ltd and Geoscience Australia Dataset Ownership: GSWA and Geoscience Australia<br><strong>Files included in this download </strong> This data package release contains the final survey deliverables received from the contractor Thomson Aviation, with an initial QC by CMG Operations Pty Ltd, then peer reviewed by Dr Jack McCubbine (Geoscience Australia).
