It includes readily usable geophysical forward operators for airborne electromagnetics (AEM), controlled-source electromagnetics (CSEM) and magnetotellurics (MT) (see http://pid.geoscience.gov.au/dataset/ga/146706, for the package and example code see https://github.com/GeoscienceAustralia/HiQGA.jl).Under development since 2020, the package was a deliverable funded under the Federal Governments Exploring for the Future programme (see https://www.eftf.ga.gov.au/about)2022 Darling Curnamona Delamerian AEM surveyThe next scheduled AEM release will be the 14 500 line km Darling Curnamona Delamerian (DCD) dataset, acquired across three states (NSW, SA, and Vic) over a period of four months as part of the Exploring for the Future (EFTF) programme in 2022. Set up as a deep dive project with five focus areas (Figure 3), the AEM will assist in defining the mineral potential of the Curnamona Province and Delamerian Orogen, together with providing a better understanding of groundwater quality, resources and storage potential.The AEM acquisition was accompanied with magnetotelluric surveying and deep crustal reflection seismic studies. After integration of geochemistry and other geoscience datasets, geophysical data releases will be followed by mineral potential assessments, cover thickness maps and other interpretative products later in 2023 Figure 3.The Darling Curnamona Delamerian AEM survey, 2022.
