East Australian climate extremes through the Holocene. The project aims to document climate variability in eastern Australia over the Holocene, the last 11,500 years. It seeks to develop Australia’s two highest-resolution Holocene climate records using novel techniques to infer past rainfall, temperature and evaporation. The project will combine the expertise of international drought and climate specialists with novel techniques developed by the Australian investigators to derive an unparalleled ....East Australian climate extremes through the Holocene. The project aims to document climate variability in eastern Australia over the Holocene, the last 11,500 years. It seeks to develop Australia’s two highest-resolution Holocene climate records using novel techniques to infer past rainfall, temperature and evaporation. The project will combine the expertise of international drought and climate specialists with novel techniques developed by the Australian investigators to derive an unparalleled record of drought duration, frequency and intensity. In particular, the project aims to determine the frequency, duration and causes of mega-droughts in eastern Australia, of which little is known. Expected project outcomes include improved decision making capacity for natural resource management, and planning.Read moreRead less
Establishing baseline ecological conditions for the Lower Lakes, South Australia: the applications of palaeoecology to sustainable resource management. The Lower Lakes of the Murray River are in a critical ecological state due to record low water levels. Management of these lakes needs to integrate water security demands with maintaining healthy ecosystem functions. Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based ....Establishing baseline ecological conditions for the Lower Lakes, South Australia: the applications of palaeoecology to sustainable resource management. The Lower Lakes of the Murray River are in a critical ecological state due to record low water levels. Management of these lakes needs to integrate water security demands with maintaining healthy ecosystem functions. Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based on assumptions about what the Lakes were like naturally (pre-European). This study will reconstruct environmental variability within the Lower Lakes over the past 7000 years, concentrating on salinity to document the extent of marine incursion, and pH to examine the impacts of acid sulphate release from exposed sediments during low flow events.

Climate and environmental history of SE Queensland dunefields. This project aims to generate fundamental information about the timing and mode of formation of sand dunes in the world's largest downdrift sand system, Cooloola and Fraser Island, Queensland. The project aims to provide a world class record of climate variability, sea-level change and long term climate change from the sub-tropics of Australia, an area critical to understanding global climate links and sea-level change but where high ....Climate and environmental history of SE Queensland dunefields. This project aims to generate fundamental information about the timing and mode of formation of sand dunes in the world's largest downdrift sand system, Cooloola and Fraser Island, Queensland. The project aims to provide a world class record of climate variability, sea-level change and long term climate change from the sub-tropics of Australia, an area critical to understanding global climate links and sea-level change but where high quality long-term records are sparse and little investigated. This project will also underpin the outstanding universal value of the Fraser Island World Heritage Area which is based on the area being the world's largest sand island, but for which scientific understanding of the sand dunes is remarkably poor.Read moreRead less
East Asian Monsoon response to periods of abrupt global change. This proposal aims to investigate the response of the East Asian Monsoon to abrupt climatic change, under baseline states of both warm and cool climate. The research is significant as it utilises unique, precisely dated sediments from Japan, and novel approaches to quantifying spatial and temporal climate patterns. The research will improve understanding of the nature and causes of decadal-scale changes in monsoon precipitation, wit ....East Asian Monsoon response to periods of abrupt global change. This proposal aims to investigate the response of the East Asian Monsoon to abrupt climatic change, under baseline states of both warm and cool climate. The research is significant as it utilises unique, precisely dated sediments from Japan, and novel approaches to quantifying spatial and temporal climate patterns. The research will improve understanding of the nature and causes of decadal-scale changes in monsoon precipitation, with relevance for constraining the trajectory of the future monsoon, and the risks of prolonged drought and flood. The findings will benefit the Asian people, for whom the monsoon has major economic, social and environmental importance. In turn, this will benefit Australia, via economic and climatic ties to Asia.Read moreRead less

Summary
Sonic drilling to provide contamination-free core sampling of rock and unconsolidated sediment. Australia is the world's driest inhabited continent. Understanding environmental and climatic changes, from the temperate period when humans arrived about 50,000 years ago to the present state of widespread aridity, is crucial for modelling future climate change. This facility will provide new generation drilling equipment which is necessary to obtain accurate records.

High-resolution ITRAX XRF core scanning facility for global change research. 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 c ....High-resolution ITRAX XRF core scanning facility for global change research. 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
