Application of the multichannel self-potential method to detection of seepage from mine tailings impoundments. This project will use a modern multichannel geophysical data acquisition system to study short and long-term variations in self-potential measurements at a tailings dam. The project will use the self-potential method to detect fluid seepage paths through the dam wall, and will use numerical models to make quantitative estimates of seepage rates. The major outcomes of the project will ....Application of the multichannel self-potential method to detection of seepage from mine tailings impoundments. This project will use a modern multichannel geophysical data acquisition system to study short and long-term variations in self-potential measurements at a tailings dam. The project will use the self-potential method to detect fluid seepage paths through the dam wall, and will use numerical models to make quantitative estimates of seepage rates. The major outcomes of the project will be a rigorous appraisal of the utility of the self-potential method for mapping seepage in an operating mine environment, and construction of fluid flow paths through the dam which can be used to guide future remediation work.Read moreRead less
Time-lapse geophysical monitoring of acid mine drainage at Savage River Mine, North-western Tasmania. This project will apply geophysical methods to image and monitor the subsurface distribution, and short and long-term temporal variations in ground conductivity associated with Acid Mine Drainage (AMD) at the Savage River Mine, Tasmania. AMD is a major environmental problem affecting mining operations across Australia. Geophysical techniques are inexpensive means of mapping variations in subsu ....Time-lapse geophysical monitoring of acid mine drainage at Savage River Mine, North-western Tasmania. This project will apply geophysical methods to image and monitor the subsurface distribution, and short and long-term temporal variations in ground conductivity associated with Acid Mine Drainage (AMD) at the Savage River Mine, Tasmania. AMD is a major environmental problem affecting mining operations across Australia. Geophysical techniques are inexpensive means of mapping variations in subsurface electrical conductivity related to changes in groundwater levels and contaminant concentration. The major outcomes of this project will be development of appropriate geophysical methods and interpretation techniques for delineation and monitoring of AMD at sites characterised by high seasonal rainfall and significant topography.Read moreRead less

Summary
Turbulent mixing in the deep Southern Ocean. Mixing in the Southern Ocean strongly affects the transport and storage of heat, carbon, and nutrients in the global ocean and hence climate itself. Yet processes generating mixing in the Southern Ocean remain poorly understood and inadequately represented in present ocean and climate models. This project aims to: understand mixing processes based on an innovative approach combining sparse observations and computer simulations; and to implement this u ....Turbulent mixing in the deep Southern Ocean. Mixing in the Southern Ocean strongly affects the transport and storage of heat, carbon, and nutrients in the global ocean and hence climate itself. Yet processes generating mixing in the Southern Ocean remain poorly understood and inadequately represented in present ocean and climate models. This project aims to: understand mixing processes based on an innovative approach combining sparse observations and computer simulations; and to implement this understanding into a state-of-the-art climate model to study mixing impacts on the ocean circulation and climate. This project aims to produce substantial improvements in climate models and allow Australia to predict and respond more effectively to climate change.Read moreRead less
Establishing the reference frame using astronomical and space-geodetic observations. Australia is increasingly dependent on spatial positioning and spatial data, yet mostly relies upon international agencies and research organisations to provide regular updates of coordinates and reference frame definition used on Earth. Improving the accuracy of the reference frame definition and our understanding of errors in the space-based measurements will provide new insights for studies of the Earth.

Australia is increasingly dependent on spatial positioning and spatial data, yet mostly relies upon international agencies and research organisations to provide regular updates of coordinates and reference frame definition used on Earth. Improving the accuracy of the reference frame definition and our understanding of errors in the space-based measurements will provide new insights for studies of the Earth. The research will yield results in studies of national significance, such as sea level rise, the effects of melting polar regions, and crustal deformation, as well as developing Australia's expertise in exploiting observations of the Earth from space.Read moreRead less
Probing the Australian-Pacific plate boundary: Macquarie Ridge in 3-D. This project aims to advance understanding of the Australia-Pacific plate boundary - the Macquarie Ridge Complex - in the Southern Ocean.
It will be the first study to elucidate the processes generating the world's largest submarine earthquakes not associated with active subduction, which may lead to understanding of how subduction initiates, the mechanism of earthquakes occurring at convergent margins, and more accurate est ....Probing the Australian-Pacific plate boundary: Macquarie Ridge in 3-D. This project aims to advance understanding of the Australia-Pacific plate boundary - the Macquarie Ridge Complex - in the Southern Ocean.
It will be the first study to elucidate the processes generating the world's largest submarine earthquakes not associated with active subduction, which may lead to understanding of how subduction initiates, the mechanism of earthquakes occurring at convergent margins, and more accurate estimates of earthquake and tsunami potential.
This study will put Australia at the forefront of Earth Science research into the evolution of tectonic plates and has the potential to better inform hazard assessment efforts in the region, benefiting policy-makers and at–risk communities along the Australia coastline.Read moreRead less
