AusAEM WA 2020-21, Eastern Goldfields & East Yilgarn Airborne Electromagnetic Survey Blocks TEMPEST® airborne electromagnetic data and GALEI conductivity estimates
AusAEM (WA) 2020-21, Eastern Goldfields & East Yilgarn Airborne Electromagnetic Survey
The accompanying data package, titled “AusAEM (WA) 2020-21, Eastern Goldfields & East Yilgarn Airborne Electromagnetic Survey Blocks: TEMPEST® airborne electromagnetic data and GALEI conductivity estimates”, was released on 4 February 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 fixed-wing aircraft by CGG Aviation (Australia) Pty. Ltd. under contract to Geoscience Australia, using the TEMPEST® airborne electromagnetic system. The survey was flown at a 20-kilometre nominal line spacing over the most eastern part of the state and down to the southern coast of Western Australia. The total area encompasses close to 32,680 line kilometres of newly acquired airborne electromagnetic geophysical data. CGG also processed the data.
This package contains 18,482 line kilometres of the survey data, which have been quality-controlled, processed and inverted. The East Yilgarn Block entailed approximately 12,590 line kilometres and the Eastern Goldfields 5,892 line kilometres. The remaining data will be released as a separate package.
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.
GA 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 and TEMPEST® system specification files
3. ESRI shapefiles for the regional and infill flight lines
4. Final processed point located line data in ASEG-GDF2 format
5. Conductivity estimates generated by CGG’s EMFlow conductivity-depth transform
