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

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
Diatom lipids to reveal sea-ice history in remote Antarctic regions. This project aims to understand seasonal Antarctic sea-ice extent using molecular, geochemical, elemental and genomic characteristics of specific marine phytoplankton (diatoms). Little is known of the seasonal sea-ice variation and the position of the summer sea-ice extent a million years before satellite records, but this information is critical to determining air-sea gas exchange and ecosystem food web regulation. This projec ....Diatom lipids to reveal sea-ice history in remote Antarctic regions. This project aims to understand seasonal Antarctic sea-ice extent using molecular, geochemical, elemental and genomic characteristics of specific marine phytoplankton (diatoms). Little is known of the seasonal sea-ice variation and the position of the summer sea-ice extent a million years before satellite records, but this information is critical to determining air-sea gas exchange and ecosystem food web regulation. This project will unite geochemical and biological approaches to provide the data to improve past Antarctic ecosystem and climate models where sea-ice data is missing. Studying diatom biomarkers in deep sea cores from Australia’s Southern Ocean will redefine knowledge of Antarctic climate and provide data necessary to improve global ecosystem and climate models.Read moreRead less
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.

Laser ablation multiple split streaming: This geochemical facility with an innovative, world-leading micro-analytical capability intends to support research of fundamental and strategic problems at the frontiers of the Earth and Environmental Sciences. The facility aims to allow new insight into the age, composition, thermal history and structure of the Australian continent, as necessary for delineating mineral endowment and for tracing the sources of ore metals. It will provide a higher resolution record of climate and environmental change which will better inform assessment of the impacts, both locally and regionally. It is intended that the facility will amplify national and international scientific collaboration and create unique research opportunities for Australian-based scientists.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.
