This investigation of the history and development of the Australian monsoon will provide much needed information for the prediction of future climatic changes in the Australasian region and beyond. Furthermore, our work will elucidate the impact of current north Australian fire regimes on the strength of the Australian monsoon that is so critical to the environment and economy of the north Australian region, a region that produces wealth for Australia out of proportion to its population. The work has important policy implications for water and fire management in Northern Australia and is significant to aboriginals, pastoralists and other community groups.Read moreRead less
UPTAKE OF ATMOSPHERIC CO2 IN THE OCEANS AND IMPLICATIONS FOR GLOBAL CHANGE: NEW PROXY DEVELOPMENTS. This project aims to quantify the response of the oceans to increasing atmospheric CO2 from anthropogenic production. This will be achieved by using newly developed paleoceanographic indicators in deep sea sediments, corals and coralline sponges. These will be used to evaluate changes in seawater acidity and the response of the oceans to past variations in atmospheric CO2. The capacity and role o ....UPTAKE OF ATMOSPHERIC CO2 IN THE OCEANS AND IMPLICATIONS FOR GLOBAL CHANGE: NEW PROXY DEVELOPMENTS. This project aims to quantify the response of the oceans to increasing atmospheric CO2 from anthropogenic production. This will be achieved by using newly developed paleoceanographic indicators in deep sea sediments, corals and coralline sponges. These will be used to evaluate changes in seawater acidity and the response of the oceans to past variations in atmospheric CO2. The capacity and role of the oceans to buffer the rise of atmospheric of CO2 will be ascertained. This will provide constraints on the impact of increased seawater acidity on coral reefs such as the Great Barrier Reef.Read moreRead less
The key role of the Southern Ocean in atmospheric CO2 sequestration. The integrated approach proposed in this study aims to quantify past changes in marine productivity and its role in controlling past atmospheric CO2 variations. This will be achieved by studying deep sea sediments from the Southern Ocean, a key area with a fundamental importance in the global ocean biological pump. This research will enhance our understanding of the linkages connecting marine biota, the ocean carbon cycle and g ....The key role of the Southern Ocean in atmospheric CO2 sequestration. The integrated approach proposed in this study aims to quantify past changes in marine productivity and its role in controlling past atmospheric CO2 variations. This will be achieved by studying deep sea sediments from the Southern Ocean, a key area with a fundamental importance in the global ocean biological pump. This research will enhance our understanding of the linkages connecting marine biota, the ocean carbon cycle and global climate, providing the basis for more reliable predictions about the impacts of the recent rapid atmospheric CO2 increase. Possible remediation solutions involving marine phytoplankton to this CO2 excess will be thoroughly assessed.Read moreRead less
Complexity in climate impact assessment: a methodology to address extremes. It is something of a truism that the events and states of the changing environment that affect society tend to fall in the extremes. My goal is to develop a model-based methodology to characterize the extremes that are not usually predicted by climate models. Key extremes of importance to stakeholders in Australia and around the world include coastal flooding and fire. These events, in the context of regional climate var ....Complexity in climate impact assessment: a methodology to address extremes. It is something of a truism that the events and states of the changing environment that affect society tend to fall in the extremes. My goal is to develop a model-based methodology to characterize the extremes that are not usually predicted by climate models. Key extremes of importance to stakeholders in Australia and around the world include coastal flooding and fire. These events, in the context of regional climate variation, will act as test cases for the methodology. From this work, the likelihood of policy-relevant events in the future can be evaluated, with a robust assessment of the uncertainty.Read moreRead less
Risk assessment for environmental health in Adelaide based on weather, air pollution and population health outcomes. This is the first systematic assessment of the effect of climate variation and air pollution on population health in an Australian temperate region. It is one of the ARC's research priorities (PG 7: Responding to climate change and variability). The results will provide a more complete picture of association among air pollution, climate variability and population health in Austral ....Risk assessment for environmental health in Adelaide based on weather, air pollution and population health outcomes. This is the first systematic assessment of the effect of climate variation and air pollution on population health in an Australian temperate region. It is one of the ARC's research priorities (PG 7: Responding to climate change and variability). The results will provide a more complete picture of association among air pollution, climate variability and population health in Australia. They will also provide important information to policy-makers and communities for their relevant actions, including changes in resource management systems and the operation of these systems, a range of socioeconomic actions, infrastructure establishment, disaster prevention and emergency events response regulation, and health education and promotion campaigns.Read moreRead less
Characterising the tropical "heat engine" of global climate: combined coral, stalagmite and tree-ring records from the Indo-Pacific region. The recent anthropogenic global warming is causing polar icecap melting, sea level rise, reef coral bleaching and degradation, and increased frequency and intensity of severe droughts, floods, tropical cyclones/hurricanes/typhoons in the past decades, focusing daily media headlines worldwide.

The recent anthropogenic global warming is causing polar icecap melting, sea level rise, reef coral bleaching and degradation, and increased frequency and intensity of severe droughts, floods, tropical cyclones/hurricanes/typhoons in the past decades, focusing daily media headlines worldwide. Our study will enhance understanding of global climate change, El Niño and Asian-Australian monsoon variability and coral reef degradation, and provide improved knowledge for future predictions. The outcome will impact on our National Research Priority 1: An Environmentally Sustainable Australia, enhance Australia's leadership in coral reef research, and contribute to an improved relationship with our neighbours in science, education and training.Read moreRead less

This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality changes, pollution histories, recent geomorphological change, land-use change, introduction of invasive species and the occurrence of bushfires. A better understanding of the occurrence and timing of these major environmental issues is of national and regional importance.Read moreRead less

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
