There is increasing interest in using airborne electromagnetic (AEM) data to explore structural features hidden beneath the earth's surface. At present, 2D images of these features can be built up using approximate 1D models that predict electrical conductivity. This research will develop 2D models that allow accurate imaging of 3D structures. Applications include mineral and diamond exploration, the mapping of leakage from tailings dams, and more precise mapping of dryland salinity. The project also aims to develop a method to calibrate AEM systems, leading to more accurate environmental mapping and significant long-term economic benefits.

利用航空电磁（AEM）数据来探测隐藏在地球表面之下的结构特征越来越受到人们的关注。目前，这些特征的2D图像可以使用预测电导率的近似1D模型来构建。这项研究将开发2D模型，使3D结构的准确成像。应用包括矿物和钻石勘探、尾矿坝渗漏测绘以及更精确的旱地盐度测绘。该项目还旨在开发一种校准AEM系统的方法，从而实现更准确的环境测绘和显著的长期经济效益。
