Summary
The future of palaeoclimate and archaeological research in Australia: next generation instrumentation for chronology and environmental reconstruction. The outcomes of this project will promote a better understanding of Australia's arid continent and its surrounding marine environment, contribute to studies of global climate change, and provide new insights into the response of fragile ecosystems to such events and processes.

The outcomes of this project will promote a better understanding of Australia's arid continent and its surrounding marine environment, contribute to studies of global climate change, and provide new insights into the response of fragile ecosystems to such events and processes. The project addresses directly the National Research Priority 'Water - a critical resource', 'Responding to climate change and variability', 'Overcoming soil loss, salinity and acidity', 'Sustainable use of Australia's biodiversity' and 'Understanding our region and the world'. It provides a consortium-type platform for highly productive collaborative research and training across eight universities and one research organisation in Australia.Read moreRead less
Palaeoclimate reconstructions from the isotopic signatures of fossilised leaf waxes. This project develops a method for using the chemical signature of fossilised leaf waxes to reconstruct hydrologic change in south-eastern Australia during the Holocene (last 10,000 years) and Eocene (56-34 million years ago). Understanding climate in the geologic past is essential for testing models and projecting future climate with rising carbon dioxide.
The application of clumped isotope thermometry to the terrestrial environment. Clumped-isotope geochemistry, a novel method for measuring the temperature of formation of carbonate minerals, will be applied to terrestrial materials (soil carbonates, lake deposits and speleothems) from Australia and New Zealand. The method relates the abundance or 'clumping' of rare isotopes (for example, carbon dioxide of mass 47 as carbon-13, oxygen-18, oxygen-16) extracted from carbonates to their formation tem ....The application of clumped isotope thermometry to the terrestrial environment. Clumped-isotope geochemistry, a novel method for measuring the temperature of formation of carbonate minerals, will be applied to terrestrial materials (soil carbonates, lake deposits and speleothems) from Australia and New Zealand. The method relates the abundance or 'clumping' of rare isotopes (for example, carbon dioxide of mass 47 as carbon-13, oxygen-18, oxygen-16) extracted from carbonates to their formation temperature and is independent of the oxygen-18:oxygen-16 value of the host water from which the mineral precipitated. The materials to be investigated span the Last Glacial-Interglacial Transition and will provide robust past temperature estimates and the delta-oxygen-18 values of waters, thereby permitting hydrological balances (for example, precipitation/evaporation) to be constructed.

Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed ....Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed knowledge of how changes in fire and rain shaped the ecology and evolution of plants and animals. This knowledge is key to understanding how Australian ecosystems function and to protecting their cultural, economic and environmental values, especially as climate and fire regimes continue to change into the future.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. 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 g ....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. 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.

Summary
Stable isotope analysis of environmental and physiological samples. Mass spectrometers capable of isotope analysis are essential tools for the earth and environmental sciences, physiology and palaeoecology. This project will provide mass spectrometers for both laboratory and field conditions which will ensure Australia remains at the forefront of international research, attract collaborations and lead to outcomes of global significance.

This will provide better understanding of the trajectories of environmental change, formation of mineral deposits and identifying trade networks in prehistoric societies.Read moreRead less
Were abrupt changes in the Precambrian global carbon cycle the trigger for animal appearance and radiation on Earth? The origin of complex life and the properties that allow that life to be sustained on this planet are recorded within the geologic record. This project will reveal the role that severe perturbations of the global carbon cycle and climate had in triggering the step-wise change to animal life after billions of years of only single cell organisms.
