The AusAEM, Northeast Queensland, Australia, 2024 Airborne Electromagnetic Survey was a collaborative effort between Geoscience Australia (GA) and the Geological Survey of Queensland (GSQ). Conducted between July and October 2024, the survey covered 30,500 flight-line kilometres at a nominal line spacing of 20 kilometres, with selected infill as part of GA's Data Driven Discoveries project in the Adavale . The primary aim was to gather comprehensive airborne electromagnetic and magnetic geophysical data to better understand subsurface geological formations, contributing to mineral exploration, groundwater studies, and broader geological mapping in North-east Queensland.
The survey was flown by Xcalibur Aviation (Australia) Pty Ltd using its TEMPEST AEM system. Xcalibur also processed the data. This data package includes the acquisition and processing report, the final processed AEM data, and the results of the contractor's conductivity-depth estimates.
The survey will become part of the national AusAEM airborne electromagnetic acquisition programme, which aims to provide geophysical information to support investigations of the regional geology and groundwater system and better characterise the salinity, recharge and architecture of the aquifers within the upper few hundred metres of the subsurface.
