Tim Munday

DirectorImage result for Tim Munday"

As the platform director Tim brings an unprecedented wealth of expertise having deep domain knowledge of geophysical methods for characterising cover and their application for both minerals and/or groundwater resource assessment. This is accompanied by a strong track record in leading and contributing to multi-disciplinary research and management of regionally dispersed research teams. Tim has more than 20 years’ experience in the application of airborne geophysical methods; notably airborne electromagnetics for cover (the regolith/critical zone) characterization in 2 and 3D, as a critical part of enhanced minerals exploration. Equally extensive is his experience in the application of hydrogeophysical methods; particularly airborne and ground-based electrical, electromagnetic methods, plus borehole and surface nuclear magnetic resonance methods for groundwater and aquifer characterisation, ecosystem function, surface water – groundwater interactions and environmental applications. He has driven a research path involving the development of technologies for understanding minerals, water and environment, believing that they are intimately linked. Further to this, he has 10 years’ experience in the application of remote sensing technologies for mapping the regolith and sedimentary systems. This technical expertise combined with breadth of experience, places Tim favourably to lead the platform’s activities.

As an active researcher Tim’s current interests cover: the assessment of the cause and expression of airborne IP in Australian settings from high powered AEM systems; application of machine learning approaches to depth of cover definition; assessment of airborne EM inversion approaches to sub-basin definition and identification of mineralization in the McArthur Basin, NT; definition of appropriate geophysical methods for lithostructural definition of basin margins; application of ground time domain EM and nuclear magnetic resonance methods in aquifer characterization in Australia; integrated approaches to the use of geophysics, hydrogeology and geochemistry for improved groundwater assessments, including methodologies for transforming spatially sampled geophysical data, using hydrogeological constraints, directly to a hydrogeological model framework; and, the development of an integrated geoscientific approach to understanding the location, character and variability of groundwater resources, the sustainability of this resource, and its relationship to environmental and cultural assets (and flows) in key priority areas flagged for industrial development in outback South Australia.
