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
Water and soil resource response to past global environmental changes. The abundance and distribution of Earth's water and soil resources are strongly influenced by the spatial and temporal variability of climatic parameters. Thus, there is a need to understand how climate change, whether of natural causes or induced by human activity, impacts fluvial and soil systems. This project will use novel isotopic techniques to study the links between climate variability, chemical weathering, which produ ....Water and soil resource response to past global environmental changes. The abundance and distribution of Earth's water and soil resources are strongly influenced by the spatial and temporal variability of climatic parameters. Thus, there is a need to understand how climate change, whether of natural causes or induced by human activity, impacts fluvial and soil systems. This project will use novel isotopic techniques to study the links between climate variability, chemical weathering, which produces soil, and sediment transport, which affects fluvial systems and water resources. The composition of stable lithium, boron and calcium isotopes, and of radioactive uranium-series isotopes in sedimentary records will shed new light on our understanding of these processes.Read moreRead less
