Exploring for the Future AusAEM Eastern Resources Corridor: 2021 Airborne Electromagnetic Survey: TEMPEST® airborne electromagnetic data and GALEI inversion conductivity estimates The accompanying data package, was released on 15 September August 2021 by Geoscience Australia (GA). The package contains AEM data from the AusAEM_20 East Resources Corridor survey, which was acquired across an area spanning from Bedourie in Queensland to Cape Jervis in South Australia, and from Tibooburra in New South Wales to Warrnambool in Victoria. The coverage is more than 600,000 square kilometres of south-eastern Australia. The regional survey was flown at a 20-kilometre nominal line spacing and entailed approximately 31,500 flight-line kilometres f geophysical data. The survey was flown in three phases, by Xcalibur Aviation (Australia) Pty. Ltd. (Xcalibur), formally CGG Aviation (Australia) Pty. Ltd. (CGG), under contract to Geoscience Australia, using the TEMPEST® airborne electromagnetic system. Xcalibur Aviation also processed the data. Geoscience Australia commissioned the Exploring for the Future AusAEM Eastern Resources Corridor survey as part of the Exploring for the Future (EFTF) program. The Exploring for the Future AusAEM program has been expanded with funding from the Geological Surveys of Western Australia and Queensland. Geoscience Australia acknowledges the valuable in-kind support from all Australian state and territory geological surveys in driving the new national AusAEM dataset. The program is designed to investigate the potential mineral, energy and groundwater resources of Australia driving the next generation of resource discoveries. GA managed the survey data acquisition, processing, contract, the quality control of the survey and generating two of the three inversion products included in the data package.
