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
The lost ocean of eastern Australia and its critical metals endowment. This project aims to unravel the tectonic origin and economic potential of ultramafic rocks (rocks which host elevated concentrations of nickel, cobalt, chromium, and platinum-group elements). Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial ....The lost ocean of eastern Australia and its critical metals endowment.

Such rocks are outcropping in eastern Australia along a contorted ~1500 km long belt that may record relics of an ancient ocean. Through detailed mapping and cutting-edge analytical techniques, the project is expected to fill a crucial knowledge gap in Australian tectonics, while providing information on ore mineralisation. The expected outcomes, including new tectonic models unveiling the scale, geometry, and economic potential of the ultramafic bodies, could benefit critical mineral exploration, carbon storage solutions, and geoecology conservation.Read moreRead less

SHRIMP SI - Microscale stable-isotope analysis in the Earth Sciences. 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.

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

Summary
A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, an ....A stable-isotope mass spectrometer for novel determinations of past temperatures. Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, and directly measures past temperatures. This will have a profound effect on our understanding of environmental changes on both short and long time scales, and permit a better understanding of the hydrological balances within the landscape.Read moreRead less
Unravelling how aquatic coastal networks regulate nitrogen removal . The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches.

The aim of this project is to determine the nitrogen removal pathways of the coastal zone using a number of innovative field and modelling approaches. Little is known about how the complex coastal landscape controls trade-offs that maximise nitrogen removal but minimise nitrous oxide (a potent greenhouse gas) emissions. The outcomes of this study will significantly advance our understanding of the coastal zone in regional and global nitrogen budgets. This will provide significant benefits such as a new science-based quantitative framework to facilitate best practice management to reduce terrestrial nitrogen loads and associated downstream impacts such as eutrophication, and reduce nitrous oxide emissions and associated global warming.

Unravelling the drivers of greenhouse gas emissions in estuaries. The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling ....Unravelling the drivers of greenhouse gas emissions in estuaries. The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling across a range of undisturbed to disturbed systems. It is intended that this project will provide information for conceptualising, calibrating and verifying models, including green-house gas production. Good models, and the data that support them, such as that provided by this study, are critical for the efficient allocation of management resources in Australian coastal systems, including by our partners. The findings from this project will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.Read moreRead less
