Accurate calibration and interpretation of airborne electromagnetic data. 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.

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.Read moreRead less
SCANEM : A Scanning and Inspection Method for Urban Pipeline Systems. Water and sewage utilities are crucial factors limiting economic growth and urban amenity. However many of these facilities are subject to corrosion, fracture and collapse and new strategies are now required to provide a sound basis for systematic remediation and replacement. Suitable strategies involving a structural audit and statistical analysis have been proposed by CSIRO and Tyco Water. However new geophysical inspection ....SCANEM : A Scanning and Inspection Method for Urban Pipeline Systems. Water and sewage utilities are crucial factors limiting economic growth and urban amenity. However many of these facilities are subject to corrosion, fracture and collapse and new strategies are now required to provide a sound basis for systematic remediation and replacement. Suitable strategies involving a structural audit and statistical analysis have been proposed by CSIRO and Tyco Water. However new geophysical inspection methods are now required to provide the key physical parameters relating to pipeline condition. Hopefully the EM inspection tool resulting from this project will provide the industrial partners with a unique capacity to satisfy a major global market.Read moreRead less
