Australian membership of the International Ocean Discovery Program: This project is for an Australian membership of the International Ocean Discovery Program. The Program will recover drill cores, situate observatories, and conduct down-hole experiments in all the world's oceans from lowest to highest latitudes to address fundamental questions about Earth's history and processes within four high-priority scientific themes: climate and ocean change - reading the past and informing the future; biosphere frontiers - deep life, biodiversity, and environmental forcing of ecosystems; earth connections - deep processes and their impact on earth's surface environment; earth in motion - processes and hazards on a human time scale.Read moreRead less
Sediment transport in upwelling currents and its relevance to an active petroleum system in the Morum Sub-basin, South Australia. Australia had a trade deficit of $3.5 billion in petroleum products in 2005 and this is forecast to increase dramatically in the future. Giant oil fields may exist in the Morum Sub-basin and their exploitation could significantly reduce Australia's trade deficit in petroleum products. It would also reduce Australia's reliance on oil form politically unstable parts of ....Sediment transport in upwelling currents and its relevance to an active petroleum system in the Morum Sub-basin, South Australia.

Giant oil fields may exist in the Morum Sub-basin and their exploitation could significantly reduce Australia's trade deficit in petroleum products. It would also reduce Australia's reliance on oil form politically unstable parts of the globe. Any exploration activity and subsequent exploration success would have a significant effect on the rural economy based around Portland, the main port in the area, through which most of the logistics would flow.Read moreRead less
Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entir ....Longshore Sediment Supply to the Deep Ocean.

Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entirely new exploration model for deepwater hydrocarbons, 2) provided new expertise and seabed maps for generating a superior marine naval defence capability.Read moreRead less
Cyclostome bryozoans: Their use as paleoceanographic, paleoclimatologic and paleoenvironmental proxies throughout the cenozoic of southern Australia. The unravelling of ocean evolution relies largely on data from fossils - geochemical proxies of ancient oceans. Southern Australia contains an inrivalled 45 million-year old record of cool-water carbonate sedimentation and thus global paleoceanography. Currently, the only proxies available in these extensive sediments are brachiopods and planktic f ....Cyclostome bryozoans: Their use as paleoceanographic, paleoclimatologic and paleoenvironmental proxies throughout the cenozoic of southern Australia. The unravelling of ocean evolution relies largely on data from fossils - geochemical proxies of ancient oceans. Southern Australia contains an inrivalled 45 million-year old record of cool-water carbonate sedimentation and thus global paleoceanography. Currently, the only proxies available in these extensive sediments are brachiopods and planktic foraminfers. However, these sediments contain prolific low-magnesium calcite bryozoans, particularly cyclostomes, that could be used instead. This research will assess such bryozoans and test their usefulness and reliability, utilising existing extensive modern marine and Tertiary samples, data bases and sections. Such potential proxies would be globally useful for limestones from the last 500My.Read moreRead less
The stratigraphic architecture of continental margins (MARGINS). The project seeks to increase our understanding of how continental margins develop. Emphasis is given to studying the controls exerted on sedimentation by sea-level change, climate cycling, ocean front location, current-deposition and tectonics, using the southwest Pacific (temperate eastern NZ) as the prime fieldwork area. Sediment being transported across continental margins passes through a number of energy fences (e.g. piedmont ....The stratigraphic architecture of continental margins (MARGINS). The project seeks to increase our understanding of how continental margins develop. Emphasis is given to studying the controls exerted on sedimentation by sea-level change, climate cycling, ocean front location, current-deposition and tectonics, using the southwest Pacific (temperate eastern NZ) as the prime fieldwork area. Sediment being transported across continental margins passes through a number of energy fences (e.g. piedmont, shoreline, wave-base, storm-zone, shelf-edge), which together modulate sediment transport and deposition. These fences differ in their relative positions, magnitudes and effects on different margins. The research will combine onland and offshore studies, builds on data collected during ODP Leg 181, and is integrated with the international MARGINS "source to sink" program.Read moreRead less

The Program studies the history and current activity of the Earth by conducting seagoing coring expeditions and monitoring of instrumented boreholes, using globally unique infrastructure that Australians would otherwise have no access to. Program outcomes include understanding past global environmental change on multiple time scales, the deep biosphere, plate tectonics, formation and distribution of resources, and generation of hazards. These outcomes are paramount to Australia’s national science and research priorities, and societal and economic prosperity.Read moreRead less
Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine ....Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine how chemical elements, including metals, are distributed in these reactions. The study seeks to create robust geochenmical models for understanding geochemical and ore-forming processes. Improved understanding of ore deposition will enhance the long-term viability of Australia's metals sector.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.

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
Determining the relative roles of dispersal and vicariance in the assembly of the New Zealand fauna. New fossils from New Zealand's St Bathans Fauna (19-16 million years) will revolutionise our understanding of the shared biodiversity and evolutionary history of New Zealand and Australia through the first views of the origin and evolution of major Gondwanan groups including frogs, crocodiles, birds and bats on the now mostly-drowned continent Zealandia.
