Assessment of the potential consequences of large-scale eradication of rice grass from the Tamar Estuary, Tasmania. Introduced Rice grass has trapped large volumes of intertidal sediment, yet reduced amenity values of the Tamar Estuary, transforming beaches into muddy rice grass meadows, threatening aquaculture industries, and silting up coastal developments.

Introduced Rice grass has trapped large volumes of intertidal sediment, yet reduced amenity values of the Tamar Estuary, transforming beaches into muddy rice grass meadows, threatening aquaculture industries, and silting up coastal developments. This project will investigate the consequences of rice grass eradication, by determination of sediment volume trapped, contaminants contained, and monitoring of processes active after removal. The outcomes of this research will enable informed decisions on management of the Tamar rice grass infestation, and provide an understanding the impacts of large scale eradication to management authorities of similar infestations in Victoria, New Zealand, Europe, China and the USA.Read moreRead less

Scanning electron microscopy is a basic analytical tool for imaging surfaces of natural and synthetic materials and identification of nanometre-scale features and their compositions. At the University of Tasmania, it supports four of our six designated priority research themes: Antarctic and Marine Studies, Environment, Frontier Technologies, and Sustainable Primary Production. Our research depending on this technique includes many fundamental and applied topics from a wide range of disciplines, such as developing portable detection devices for explosives, finding more efficient and sustainable ways to explore for ore, investigating the effects of climate change on marine ecosystems and improving salinity and drought tolerance of crops.Read moreRead less
Pyrite: a deep-time capsule of ocean chemistry and atmosphere oxidation. Surprisingly little is known about trace element trends in past oceans, even though these data are vital for interpreting the evolution of the Earth's atmosphere, evolutionary pathways of marine life and cycles of major mineral deposits. Using laser-based analysis of sedimentary pyrite in deep marine rocks, this project aims to produce, for the first time, temporal variation curves for 25 trace elements in seawater over the ....Pyrite: a deep-time capsule of ocean chemistry and atmosphere oxidation. Surprisingly little is known about trace element trends in past oceans, even though these data are vital for interpreting the evolution of the Earth's atmosphere, evolutionary pathways of marine life and cycles of major mineral deposits. Using laser-based analysis of sedimentary pyrite in deep marine rocks, this project aims to produce, for the first time, temporal variation curves for 25 trace elements in seawater over the last 3.5 billion years. Preliminary research has validated the technique and demonstrated major changes in certain trace elements over geologically short periods. Outcomes will assist the minerals industry in the discovery of new deposits of zinc, copper, gold and iron ore in Australia.Read moreRead less

Summary
A new generation fast mapping Raman system. This fast-imaging Raman facility will give researchers at the University of Tasmania a new tool to rapidly analyse the chemical properties of a wide range of materials in a non destructive way. It will complement other instrumentation and support a diverse range of research areas addressing several national research priorities.

This would establish new research strengths in the field of earth and materials science. In particular, it may improve efficiencies of discovery and recovery of ore deposits and develop environmentally friendly processes for waste disposal. Read moreRead less
Marine Geological Investigation of the Naturaliste Plateau and Diamantina Zone - the tectono-magmatic development of a non-volcanic passive margin. Australia's continental margins impact enormously on our major industries including tourism, hydrocarbon production and fisheries, and are particularly significant with respect to biodiversity and hazard planning (both long and short term), yet knowledge of the seafloor of our margins is desperately poor. To contribute to alleviating this problem, we ....Marine Geological Investigation of the Naturaliste Plateau and Diamantina Zone - the tectono-magmatic development of a non-volcanic passive margin. Australia's continental margins impact enormously on our major industries including tourism, hydrocarbon production and fisheries, and are particularly significant with respect to biodiversity and hazard planning (both long and short term), yet knowledge of the seafloor of our margins is desperately poor. To contribute to alleviating this problem, we will use the R/V Southern Surveyor research vessel to produce swath mapping imagery and dredge samples from the seafloor of a geologically fascinating part of the southern section of the Western Australian margin dominated by the Naturaliste Plateau and Diamantina Zone.

The role of melting of oceanic crust within the subduction factory: A melt inclusion approach. Continental crust is ultimately generated in subduction zones, where oceanic crust is recycled back into the mantle along deep ocean trenches, producing island arcs. Processes occurring in the subduction 'factory' are poorly understood, but dehydration of old subducted oceanic crust is usually invoked to provide water that triggers mantle melting and arc magmatism. Evidence is accumulating that in many ....The role of melting of oceanic crust within the subduction factory: A melt inclusion approach. Continental crust is ultimately generated in subduction zones, where oceanic crust is recycled back into the mantle along deep ocean trenches, producing island arcs. Processes occurring in the subduction 'factory' are poorly understood, but dehydration of old subducted oceanic crust is usually invoked to provide water that triggers mantle melting and arc magmatism. Evidence is accumulating that in many locations the subducted oceanic crust may melt, rather than simply dehydrate. I will test this using studies of melt inclusions (droplets of melt trapped by crystals growing in the magma), and will better constrain the input-output budgets of the subduction factory.Read moreRead less
Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones.

The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integrating multi-method thermochronological and structural data on major Meso-Cenozoic Central Asian fault systems. The resulting time-integrated tectonic model will aid in the understanding of the India-Eurasia collision, the building of the mountainous Central Asian landscape and its influence on the Asian climate.Read moreRead less

The project aims to reconstruct 250 million years of landscape evolution in response to rifting and break-up of the Gondwana supercontinent, using the innovative approach of combining regional thermochronology with global plate tectonic models. From these reconstructions, the time-integrated record of exhumation and erosion at the continental margins will be revealed at an unprecedented scale. The main expected outcome will be a deep time archive of the relationships between tectonic forcing, continental erosion and the global climate, which may assist predictions and debate on future climate change. The outcomes will also provide economic benefits as they will inform on the exhumation and preservation of (critical) mineral resources.Read moreRead less
