Summary
Rapid climate change, early modern human dispersal, and Neanderthal demise. Why are we the only surviving human species? This project aims to investigate whether seasonal environmental changes associated with rapid climate change events played a role in the expansion of our own species and the demise of Neanderthals between 60,000-30,000 years ago. The project will generate quantitative, sub-seasonal records of past climate variability using novel multi-proxy analyses from key archaeological sit ....Rapid climate change, early modern human dispersal, and Neanderthal demise. Why are we the only surviving human species? This project aims to investigate whether seasonal environmental changes associated with rapid climate change events played a role in the expansion of our own species and the demise of Neanderthals between 60,000-30,000 years ago. The project will generate quantitative, sub-seasonal records of past climate variability using novel multi-proxy analyses from key archaeological sites, offering a framework for understanding early human responses to extreme climate fluctuations. This may inform our strategies for coping with future extreme scenarios. These unparalleled records will also provide data to test and refine climate models, enabling a better understanding of Earth’s climate system. Read moreRead less
Understanding interglacial diversity. This project intends to improve our understanding of interglacial processes. Interglacials, the relatively brief warm intervals of Quaternary ice-age cycles, have varied significantly over the last 800 000 years in terms of their duration, timing, intensity and complexity. The reason for such diversity has eluded palaeoclimatologists for decades. This is because of the difficulty of dating marine and ice records, which best preserve interglacial histories.

Interglacials, the relatively brief warm intervals of Quaternary ice-age cycles, have varied significantly over the last 800 000 years in terms of their duration, timing, intensity and complexity. The reason for such diversity has eluded palaeoclimatologists for decades. This is because of the difficulty of dating marine and ice records, which best preserve interglacial histories. The projects plans to compile precisely dated time series of past interglacials that can be linked directly to these records, allowing robust comparisons between interglacial properties and changes in Earth's astronomical parameters. This would advance palaeoclimate theory and provide a new perspective on the future evolution of the climate system.Read moreRead less

Summary
A mass spectrometer to analyse carbonate isotope records of Australia's climate, soil and groundwater history. Water is a critical resource in Australia, yet there is a fundamental lack of knowledge about the causes and timing of groundwater recharge in the past. This facility will allow researchers to better understand climate and groundwater interactions through high resolution isotope analysis of deposits, such as cave stalagmites and marine corals.

Archaeology and natural history. This project aims to provide critical new information on the archaeology and natural history of one of the world’s largest unregulated desert river systems. Mithaka country incorporates the highly significant Channel Country on the eastern edge of Australia's arid centre. Preliminary research has identified more than 70 large site complexes that provide critical insights on how the Mithaka people adapted to this unique environment and took part in Australia's mos ....Archaeology and natural history. This project aims to provide critical new information on the archaeology and natural history of one of the world’s largest unregulated desert river systems. Mithaka country incorporates the highly significant Channel Country on the eastern edge of Australia's arid centre. Preliminary research has identified more than 70 large site complexes that provide critical insights on how the Mithaka people adapted to this unique environment and took part in Australia's most extensive long distance trade systems. The project will study the archaeological landscape, artefacts and an extensive in-situ skeletal record in the context of a detailed palaeoenvironmental study. It will provide a new cultural-environmental history of this landscape and provide the Mithaka with multiple strands of connection to their ancestral land and culture and support their aspirations to create employment through rangers programs, education and cultural tourism.Read moreRead less
Sedimentary processes on sandy coasts in southern Australia. This project aims to reconstruct sedimentary processes and evolution of key coastal plains in southern Australia. These low-lying coasts, and the settlements and infrastructure on them, are vulnerable to inundation and shoreline erosion. Past behaviour of different types of coasts will be determined by combining innovative geospatial techniques to map morphology and past changes, geophysical imaging of stratigraphy and geochronology. T ....Sedimentary processes on sandy coasts in southern Australia. This project aims to reconstruct sedimentary processes and evolution of key coastal plains in southern Australia. These low-lying coasts, and the settlements and infrastructure on them, are vulnerable to inundation and shoreline erosion. Past behaviour of different types of coasts will be determined by combining innovative geospatial techniques to map morphology and past changes, geophysical imaging of stratigraphy and geochronology. The outcome will be models that explain responses to sediment availability, past storm history and sea-level changes. This will benefit sustainable coastal planning and management, providing geomorphological evidence to support erosion hazard assessments of these and adjacent coasts.Read moreRead less
When the ice melts: a new perspective on the causes of Quaternary glacial terminations. The project will assemble an unprecedented palaeoclimate time series extending back to 1.2 million years ago that will allow marine and ice core records to be placed onto an absolute time scale. This will allow testing of fundamental hypotheses on why the Earth's climate shifts from glacial to interglacial states, with flow-on effects to climate models.

A coupled high temperature elemental analyser - gas chromatograph - mass spectrometer for climate, water and ecological research: This project is for a high temperature, elemental analysis, gas chromatography, isotope mass spectrometry facility. This would permit the analysis of the isotopes of up to four elements in a range of environmental samples such as tree cellulose, ecological samples and dissolved nutrients in surface and ground waters. Results will help improve our understanding of climate - surface water - ground water interactions, ecosystem function, and past climate and environmental change. The new facility will meet the need for organic isotope analyses to better understand the underlying physical processes.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.
