Dating Murujuga's Rock Art: new scientific approaches. The Dampier Archipelago is on Australia's National Heritage List because of its significant rock art and stone features. Known as Murujuga to its traditional custodians, this land- and seascape has over 1 million art works. While the scientific and cultural significance of this area is acknowledged, we still know little about the age of this landscape, the regional palaeoclimatology, and the timing and intensity of rock art production since ....Dating Murujuga's Rock Art: new scientific approaches. The Dampier Archipelago is on Australia's National Heritage List because of its significant rock art and stone features. Known as Murujuga to its traditional custodians, this land- and seascape has over 1 million art works. While the scientific and cultural significance of this area is acknowledged, we still know little about the age of this landscape, the regional palaeoclimatology, and the timing and intensity of rock art production since Aboriginal people moved into this region 50,000 years ago. This project will develop new scientific approaches to direct-dating engravings and stone features, reconstruct climate from geological proxies, and model voyaging opportunities as this unique cultural estate transformed to an archipelago.Read moreRead less
Climate extremes and landscape responses across continental Australia. This project aims to determine the magnitude, frequency and duration of dry and wet extremes across the Australian continent over the last thousand years and examine landscape responses to such climate extremes. Using terrestrial records from key lake locations, the project expects to construct a record of mega-lakes and mega-droughts and determine whether such climatic phenomena are becoming more frequent or severe through t ....Climate extremes and landscape responses across continental Australia. This project aims to determine the magnitude, frequency and duration of dry and wet extremes across the Australian continent over the last thousand years and examine landscape responses to such climate extremes. Using terrestrial records from key lake locations, the project expects to construct a record of mega-lakes and mega-droughts and determine whether such climatic phenomena are becoming more frequent or severe through time. The project will develop palaeoclimatic data at sub-centennial resolution, examining the spatial coherence of the climate extremes. The project will integrate this with both the historical record and global climate modelling, allowing us to assess the dominant oceanographic and atmospheric conditions that lead to such extremes.Read moreRead less
Developing reliable chronologies for extinct Australian Pleistocene megafauna from museum fossil collections. Our ability to understand the timing of prehistoric extinction events is critical, but can only be achieved by reliable dating methods. This project will adopt several new and exciting methodologies in the direct dating of fossils to determine the chronological sequence and the timing of extinction of the Pleistocene megafauna.

Summary
Tracking the response of the Australian climate to abrupt climate change. This project will use cutting-edge climate proxy analyses to reconstruct the response of the Australian climate system to global climate change over the last 2,000 years. The results will provide significant insight in to how future global climate change will impact on social, biological and physical systems in Australia.
Testing the mechanisms and effects of abrupt and extreme climate change. This project aims to resolve the timing, rate of change, mechanisms and effects of past abrupt and extreme global climate change. These are uncertain for abrupt and extreme warming events in the recent geological record, due to difficulties comparing terrestrial and marine palaeoclimate and faunal records on radiocarbon timescales with independently dated ice cores over the last 50,000 years. By using yearly-resolved tree r ....Testing the mechanisms and effects of abrupt and extreme climate change. This project aims to resolve the timing, rate of change, mechanisms and effects of past abrupt and extreme global climate change. These are uncertain for abrupt and extreme warming events in the recent geological record, due to difficulties comparing terrestrial and marine palaeoclimate and faunal records on radiocarbon timescales with independently dated ice cores over the last 50,000 years. By using yearly-resolved tree ring records, the project will discover when, how and what effect abrupt and extreme change had on global climate and species/ecosystems.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.
Understanding the drivers and impacts of long-term Antarctic ice sheet change. This project will extend historical records of change and develop an understanding of the complex linkages between the climate and Antarctic ice sheet dynamics. The results will thereby assist in identifying the mechanisms of the past and future ice sheet stability and be communicated to the general public by enhancing scientific understanding.

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. These projects will build on ....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. 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
