AusAEM-WA, Southwest-Albany Airborne Electromagnetic Survey Blocks

AusAEM-WA, Southwest-Albany Airborne Electromagnetic Survey Blocks:: SkyTEM® airborne electromagnetic data and GALEI inversion conductivity estimates

The accompanying data package, titled “AusAEM-WA, Southwest-Albany Airborne Electromagnetic Survey Blocks:: SkyTEM® airborne electromagnetic data and GALEI inversion conductivity estimates”, was released on 4 November 2021 by Geoscience Australia (GA) and the Geological Survey of Western Australia.

The data represents the first phase of the AusAEM2020 (WA) survey flown with a with a rotary aircraft contracted to Geoscience Australia, using the SkyTEM® airborne electromagnetic system. The survey was flown at a 20-kilometre nominal line spacing over the most south-western part and down to the southern coast of Western Australia. The area encompasses close to 12,500 line kilometres of newly acquired airborne electromagnetic geophysical data.

This package contains the total (~12,500) of survey data which have been quality-controlled, processed, modelled and inverted both by the contractor and by GA. The survey was divided in four blocks, flown east-west and north-south direction. Since the survey covers two standard UTM zones 50 and 51, wherever projected Map Grid of Australia (MGA) easting and northing coordinates are used they are referenced to MGA Zone 50. All four block’s projected grid coordinates have been supplied in GDA2020 MGA Zone 50 datum, and contain the geodetic latitude and longitude WGS84 coordinate fields

Geoscience Australia and Western Australia (Department of Mines, Industry Regulation and Safety) commissioned the AusAEM 2020 survey as part of the national airborne electromagnetic acquisition program, to complete 20km line separation AEM coverage over WA. The program is designed to deliver freely available pre-competitive geophysical data to assist in the investigation and discovery of potential mineral, energy and groundwater resources within Australia. Funding for the survey came from the Western Australian government’s Exploration Incentive Scheme.

Geoscience Australia managed the survey data acquisition, processing, contracts, quality control of the survey and generated the inversion products included in the data package.

The data release package contains

1. A data release package summary PDF document.

2. The survey logistics and processing report.

3. KML and Shapefiles for the regional flight lines.

4. Final processed point located line data in ASEG-GDF2 format.

5. Conductivity estimates generated by SkyTEM’s Workbench.

6. Conductivity estimates and products (suitable for various 3D packages) generated by Geoscience Australia's Layered Earth Inversion algorithm.
