Abstract
From being a poorly understood qualitative mapping tool, airborne electromagnetic (AEM) geophysics has become a mainstay for rapidly imaging the top few hundred metres of buried earth for a variety of geoscientific and environmental purposes. In this talk, we will detail GA’s quest to provide high quality, quantitative interpretation of AEM sounding data. Beginning with a 20-year historical perspective, we will shed light on how persistent focus on AEM technology directly led to AusAEM, the world’s largest (ongoing) AEM survey. We will then discuss how continuing focus on AEM has led to the development of an open source framework written in the Julia language, for subsurface imaging AND uncertainty quantification. This codebase is useful for geophysical methods beyond AEM, such as magnetotellurics and magnetic resonance. Finally, we will dwell on some real life examples using the new codebase and will look to the future of AEM@GA and its untapped potential.
