Water is essential for human existence, indeed for life's beginning. The circulation of water between the surface and the deep interior lubricates the internal dynamics that keep Earth geologically alive; it is crucial to most Earth systems, including the evolution of the hydrospher/atmosphere/biosphere, and the development of giant ore deposits. However, the origin, abundance, speciation and movements of fluids inside Earth are largely unknown, and represent key issues in modern geoscience. This CoE will integrate previously disparate fields - geology, tectonics, geochemistry, petrophysics, geophysics and dynamic modelling - to understand the workings of Earth's deep plumbing system.Read moreRead less
Rich Cousin, Poor Cousin - What Controls the Formation and Size of Orogenic Gold Deposits? What are the geological and geochemical factors that control the formation and size of gold deposits in Phanerozoic mountain belts (?orogens?)? The answer to this question lies in a combination of methods we will use to establish the importance of source, absolute timing of mineralisation, genetic links to magmas, and geochemical processes that result in the transport, and deposition of gold in three separ ....Rich Cousin, Poor Cousin - What Controls the Formation and Size of Orogenic Gold Deposits? What are the geological and geochemical factors that control the formation and size of gold deposits in Phanerozoic mountain belts (?orogens?)? The answer to this question lies in a combination of methods we will use to establish the importance of source, absolute timing of mineralisation, genetic links to magmas, and geochemical processes that result in the transport, and deposition of gold in three separate, geologically young orogens. The wider implications of this research include a greatly improved understanding of lesser known Phanerozoic orogenic gold provinces, ore genesis at convergent plate margins, and the formation of gold deposits in older terrains.Read moreRead less

Summary
The first Australian high pressure Synchrotron facility for geoscience research. In high-pressure mineral physics and chemistry, mineral properties, stress-strain relationships and processes like partial melting are applied to geophysical research about the deep Earth. This project will provide a large volume, high pressure capability at the Australian Synchrotron which will allow these mineral properties to be measured under conditions which simulate the deep earth.
Resolving the geochemistry of coastal floodplain blackwaters. Deoxygenated dead zones are a rapidly growing global crisis in coastal areas. A major cause of dead zones in our estuaries is the formation and release of blackwaters from coastal wetlands. This project will provide the knowledge necessary to manage blackwaters in these wetlands and to greatly improve the health and sustainability of our estuaries.
Electron flow in iron hyper-enriched acidifying coastal environments: reaction paths and kinetics of iron-sulfur-carbon transformations. Iron hyper-enriched acidifying coastal lowlands have a direct social, economic and environmental impact on communities in many parts of Australia. This project will determine how iron transforms and accumulates. The new knowledge will be of immediate relevance for the remediation of coastal plains.
Maximising carbon sequestration in freshwater wetlands. Maximising carbon sequestration in freshwater wetlands. This project aims to determine how manipulation of wetland hydrology can alter sulphur and iron cycling to inhibit methane emission and improve wetland net-carbon sequestration. Wetlands are among earth's most efficient ecosystems for carbon sequestration, but methane emission can offset this capacity. Redox cycling of sulphur and iron in wetlands can inhibit methane emission, but the ....Maximising carbon sequestration in freshwater wetlands. Maximising carbon sequestration in freshwater wetlands. This project aims to determine how manipulation of wetland hydrology can alter sulphur and iron cycling to inhibit methane emission and improve wetland net-carbon sequestration. Wetlands are among earth's most efficient ecosystems for carbon sequestration, but methane emission can offset this capacity. Redox cycling of sulphur and iron in wetlands can inhibit methane emission, but the precise biogeochemical processes and their efficiency are very poorly constrained due to a lack of studies—especially in Australian freshwater wetlands. This project is expected to inhibit methane emission in freshwater wetlands and maximise their net carbon sequestration efficiency.Read moreRead less
The Impact of Trawling on Nitrogen Removal through Sediment Denitrification in Western Moreton Bay. Nutrient enrichment of coastal waters is a national problem requiring urgent action. Sediment denitrification is one of the few natural processes capable of counteracting the process of eutrophication. Although trawling is undertaken in coastal water bodies around Australia the impact on sediment denitrification and the nitrogen budgets of coastal systems has never been considered. Many hundred's ....The Impact of Trawling on Nitrogen Removal through Sediment Denitrification in Western Moreton Bay. Nutrient enrichment of coastal waters is a national problem requiring urgent action. Sediment denitrification is one of the few natural processes capable of counteracting the process of eutrophication. Although trawling is undertaken in coastal water bodies around Australia the impact on sediment denitrification and the nitrogen budgets of coastal systems has never been considered. Many hundred's of millions of dollars are likely to be spent over the next ten years on the management of nitrogen enrichment of Australia's coastal waters. This study will quantify the impact of trawling on sediment denitrification; information which is critical for the efficient allocation of management resources.Read moreRead less

Stable-isotope variations of elements such as oxygen, carbon, and sulphur, preserve the most profound records of environmental conditions during the geological, biological, and climatic evolution of Earth and planets. We will build a stable isotope ion microprobe (SHRIMP SI) to examine extraterrestrial and terrestrial systems in unprecedented detail. In terrestrial applications, the main issue is accuracy at the 0.01 percent level for 20-micron spots, which we can apply to studies of development of life on Earth, climatic records, weathering, and formation of ore bodies. Sample return missions of solar wind and comets will provide unique samples related to the formation of our solar system.Read moreRead less
