Why Gigantopithecus blacki, the largest ever primate, disappeared is unknown, while humans in the region survived. This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understanding of past environmental change as a driver of megafaunal extinction in comparison with human adaption and survival.Read moreRead less

Summary
Single-grain optically-stimulated luminescence and dosimetry instruments to service the Sydney metropolitan and greater New South Wales region. This equipment will support projects that address significant environmental challenges in Australia, such as climate change and variability, coastal management and sustainable river and water management, and that assess the impacts and consequences of these challenges for populations living in environmentally sensitive areas.

This equipment will support projects that address significant environmental challenges in Australia, such as climate change and variability, coastal management and sustainable river and water management, and that assess the impacts and consequences of these challenges for populations living in environmentally sensitive areas. These projects will build on established collaborations in Australia, Antarctica and the south-west Pacific and encourage new collaborations with south-east Asian, Egyptian and Argentinean researchers, which will promote Australian research on a world stage. The use of this equipment will also pioneer new dating methodologies to further enhance Australia's place at the forefront of geochronology.Read moreRead less

Summary
A world-class rock magnetic facility to support Australian palaeomagnetic and environmental research. Magnetic properties of rocks and environmental particles provide information about a vast range of geological and environmental processes. We propose to develop a facility that will enable detection and interpretation of these magnetic signals to aid understanding of climate change, mineral exploration, and the geological development of Australia.

Summary
A regional optical dating facility in Australia. This project aims to establish an open access, end-user friendly optical dating facility in Australia. This will address shortcomings in the capacity and geographical coverage of the existing national geochronology infrastructure and enable Australian researchers to reconstruct past records of climate change, human evolution, ecological vulnerabilities, natural and man-made hazards and environmental disturbance over historical to near-million-year ....A regional optical dating facility in Australia. This project aims to establish an open access, end-user friendly optical dating facility in Australia. This will address shortcomings in the capacity and geographical coverage of the existing national geochronology infrastructure and enable Australian researchers to reconstruct past records of climate change, human evolution, ecological vulnerabilities, natural and man-made hazards and environmental disturbance over historical to near-million-year timeframes. This project is expected to increase commercial demand for geoscience services and lead to better understanding of Australia’s natural heritage and its long-term vulnerabilities.Read moreRead less
Trying times: Millennial to million year luminescence chronologies for improved reconstructions of Australian megafaunal extinctions. The causes of megafaunal extinction in Australia continue to be fiercely debated owing to chronological gaps in the palaeontological record, poorly constrained palaeoenvironmental histories and limited data on long-term faunal responses to climate change prior to human arrival. This project will utilise and advance new luminescence dating methods to provide unpara ....Trying times: Millennial to million year luminescence chronologies for improved reconstructions of Australian megafaunal extinctions. The causes of megafaunal extinction in Australia continue to be fiercely debated owing to chronological gaps in the palaeontological record, poorly constrained palaeoenvironmental histories and limited data on long-term faunal responses to climate change prior to human arrival. This project will utilise and advance new luminescence dating methods to provide unparalleled reconstructions of faunal turnover and environmental change over millennial to million year timescales. The chronologies generated through this work will provide a crucial new perspective on the ongoing megafaunal debate and will be used to test key assumptions underpinning anthropogenic- and climate-driven extinction hypotheses on local, regional and continental scales.Read moreRead less

Summary
Luminescence dating of Middle Pleistocene human histories in Europe. This project aims to ascertain the timing, context and nature of early human evolution and associated cultural turnovers in southern Europe using cutting-edge dating techniques. The project plans to use recent advances in extended-range luminescence dating to establish unequivocal, multifaceted chronologies for a comprehensive range of human fossil and stone tool sites from the Iberian Peninsula. The outcomes of this project ar ....Luminescence dating of Middle Pleistocene human histories in Europe. This project aims to ascertain the timing, context and nature of early human evolution and associated cultural turnovers in southern Europe using cutting-edge dating techniques. The project plans to use recent advances in extended-range luminescence dating to establish unequivocal, multifaceted chronologies for a comprehensive range of human fossil and stone tool sites from the Iberian Peninsula. The outcomes of this project are expected to advance our understanding of early human history by providing a critical temporal reappraisal of modelled hominin evolutionary relationships, determining the mode and tempo of cultural turnovers, and unravelling how past human populations responded to major climate change and environmental pressures.Read moreRead less
U/Th dating of coral mortality and recovery rates in the Great Barrier Reef. This project aims to use high-efficiency U-Th geochronology and palaeoecology to identify past coral mortality events and community changes in the inshore Great Barrier Reef (GBR) and quantify subsequent recovery rates across a water quality gradient. These records will then be linked to natural and human impacts, especially since European settlement. The project outcomes will improve understanding of past disturbances ....U/Th dating of coral mortality and recovery rates in the Great Barrier Reef. This project aims to use high-efficiency U-Th geochronology and palaeoecology to identify past coral mortality events and community changes in the inshore Great Barrier Reef (GBR) and quantify subsequent recovery rates across a water quality gradient. These records will then be linked to natural and human impacts, especially since European settlement. The project outcomes will improve understanding of past disturbances and recovery rates in the GBR ecosystem and help focus management in the face of increased human pressure and environmental changes.Read moreRead less
Next-generation luminescence dating techniques for Earth and archaeological science applications. Chronology is a critical component of geological and archaeological studies.

Chronology is a critical component of geological and archaeological studies. To reconstruct the evolutionary histories of Homo sapiens and other hominin species in their environmental context, we must establish reliable age estimates for key archaeological sites and Quaternary deposits. This project aims to develop new-generation sediment dating techniques using the non-fading infrared stimulated luminescence (IRSL) signal from potassium feldspars. These improved methods will be able to be applied to sites in Africa, Europe and Asia that contain important human fossils and artefacts, including the unique type localities of ‘Denisovans’ and ‘Hobbits’, to answer fundamental questions about the timing of key turning points in human evolution and dispersal.Read moreRead less
