Low-grade metamorphic phosphate geochronology: High-precision dating of ancient crustal fluid flow, hydrothermal mineralisation and the "Great Oxidation Event". Reliable dating techniques are required to obtain precise ages for ancient crustal fluid flow. Current techniques suffer from inheritance and isotopic resetting, problems that are particularly pronounced in early Precambrian rocks. This project will employ new analytical techniques to date phosphate minerals recently identified as potent ....Low-grade metamorphic phosphate geochronology: High-precision dating of ancient crustal fluid flow, hydrothermal mineralisation and the "Great Oxidation Event". Reliable dating techniques are required to obtain precise ages for ancient crustal fluid flow. Current techniques suffer from inheritance and isotopic resetting, problems that are particularly pronounced in early Precambrian rocks. This project will employ new analytical techniques to date phosphate minerals recently identified as potentially important new chronometers of ancient fluid flow, providing the first precise tectonothermal history of the Archaean Pilbara Craton. The project will also establish the age of giant iron-ore deposits across the Hamersley Province, test the various models for iron-ore formation, and provide a minimum age for the oxidation of the Earth's surface.

The mechanics of being human. This project will lead to far more detailed understanding of skull mechanics in our own lineage. Results will be of great interest to international scholars in both evolutionary and biomedical fields and help to establish a primary position for Australia in the rapidly expanding area of computer simulation of biological structure.

This project will lead to far more detailed understanding of skull mechanics in our own lineage. Results will be of great interest to international scholars in both evolutionary and biomedical fields and help to establish a primary position for Australia in the rapidly expanding area of computer simulation of biological structure. Further development on our own established protocols for automated transfer of CT scan data into finite element models, which have already improved speed, accuracy and realism, will take finite element analysis to a point at which it can be more readily applied to evolutionary, biomedical and safety design questions.Read moreRead less

Summary
High Resolution Cryogenic Field Emission Environmental Scanning Electron Microscope Facility. A high resolution variable pressure scanning electron microscope will replace aging, heavily utilised facilities. It will be accessed by existing large and diverse user groups in a mature and internationally-recognised Centre. The novel combination of a cryogenic stage and the electrostatic beam blanking modification will support continuance of the local, world-leading research and application of new ....High Resolution Cryogenic Field Emission Environmental Scanning Electron Microscope Facility. A high resolution variable pressure scanning electron microscope will replace aging, heavily utilised facilities. It will be accessed by existing large and diverse user groups in a mature and internationally-recognised Centre. The novel combination of a cryogenic stage and the electrostatic beam blanking modification will support continuance of the local, world-leading research and application of new imaging techniques, particularly in the materials and mineral sciences. Both new nanotechnology and existing globally-significant industries will utilise the unique aspects of this instrument for product refinement and maintenance of commercial leadership, in partnership with local Universities and Government agencies.Read moreRead less

The Earth System Dynamics Network for a Sustainable Australia. Earth comprises systems of enormous complexity that sustain all life and control the distribution of mineral, energy and water resources. Thus understanding these dynamic systems provides the key to sustainable resource usage. The aim of The Earth System Dynamics Network is to facilitate scientific interactions through establishment of an earth and environmental sciences grid that links national and regional data assets with high per ....The Earth System Dynamics Network for a Sustainable Australia. Earth comprises systems of enormous complexity that sustain all life and control the distribution of mineral, energy and water resources. Thus understanding these dynamic systems provides the key to sustainable resource usage. The aim of The Earth System Dynamics Network is to facilitate scientific interactions through establishment of an earth and environmental sciences grid that links national and regional data assets with high performance computing through open sourced middleware. The result will be an unparalleled predictive capacity for complex Earth systems. The outcome will be confidence in the knowledge that underpins our decisions as stakeholders to keep Australia sustainable.Read moreRead less
Antarctic marine diatoms: Key to predicting the effects of global climate change on a temperature-sensitive ecosystem. This project aims to determine the effects of global climate change on Antarctic diatoms. Diatoms are a major component of the polar phytoplankton. They are sensitive to changes in their marine environment, detection of which is an essential part of the Antarctic climate change strategy. Understanding the environmental processes that cause natural variation in extant diatoms ....Antarctic marine diatoms: Key to predicting the effects of global climate change on a temperature-sensitive ecosystem. This project aims to determine the effects of global climate change on Antarctic diatoms. Diatoms are a major component of the polar phytoplankton. They are sensitive to changes in their marine environment, detection of which is an essential part of the Antarctic climate change strategy. Understanding the environmental processes that cause natural variation in extant diatoms will make it possible to reconstruct the response of fossil diatoms, preserved in marine sediments, to past climate change. This understanding is vital for predicting the effect of future anthropogenic warming on this ecosystem.Read moreRead less
Climate dynamics of the Australian monsoon and its re-establishment following the last glacial maximum. The dynamics and linkages among elements of the global climate system (eg. North Atlantic - Antarctica- tropics) are poorly understood, particularly near the Last Glacial Maximum about 20,000 years ago. For the interval 80,000 to 10,000 years ago, we propose to produce a high-resolution environmental record(every 80 years) and dynamical model, using lacustrine sediments from the Gulf of Carpen ....Climate dynamics of the Australian monsoon and its re-establishment following the last glacial maximum. The dynamics and linkages among elements of the global climate system (eg. North Atlantic - Antarctica- tropics) are poorly understood, particularly near the Last Glacial Maximum about 20,000 years ago. For the interval 80,000 to 10,000 years ago, we propose to produce a high-resolution environmental record(every 80 years) and dynamical model, using lacustrine sediments from the Gulf of Carpentaria. We seek information on the intensity and possible disappearance of the monsoon, tropical atmospheric teleconnections with millennial-scale ice-rafting episodes at higher latitudes, and influence of aboriginal vegetation-burning on climate. Such links, if found, would profoundly alter our understanding of all tropical environments and their management.Read moreRead less
