Abstract:
Australia is covered with a significant number of AEM surveys, primarily acquired over the last three decades. Most of these data were collected with now obsolete systems or system variants. Unfortunately, many of these historical datasets contain unknown, uncertain or poorly measured system parameters and undocumented or poorly documented metadata such as acquisition and processing methods. With an increased emphasis being put on getting more information from AEM datasets, their quantitative use requires that they be interpreted using full non linear inversion methods. Unfortunately, that requires information on system geometry, transmitter waveform, and other processing parameters. Where this information is lacking, uncertainties in derived models for the conductivity structure increase.
