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

Searching for Life on Mars on Earth. Australia continues to play a world-leading role in researching planetary habitability. This project will deliver the most comprehensive investigation of Earth’s oldest known river/lake deposits, uniquely preserved in 2.8 billion-year-old rocks in Western Australia. Using the candidate’s expertise in field investigation in combination with a cutting-edge analytical approach, the project will produce a detailed reconstruction of the ancient lake environment.

This project will deliver the most comprehensive investigation of Earth’s oldest known river/lake deposits, uniquely preserved in 2.8 billion-year-old rocks in Western Australia. Using the candidate’s expertise in field investigation in combination with a cutting-edge analytical approach, the project will produce a detailed reconstruction of the ancient lake environment. Similar settings will be explored by NASA's upcoming Mars 2020 rover mission at it's landing site in Jezero Crater. Mission data will be analysed by the candidate, who will guide the selection of samples and address the overarching question of whether microbal life ever existed on Mars.Read moreRead less

The oxygenation of Earth’s early marine ecosystems. This project aims to map out the complex evolution of the Earth’s ocean ecosystems and oxygenation using marine carbonates. The oxygenation of Earth’s surface is one of the most profound processes to shape the planet, affecting all biological and geological systems. However, uncertainties remain in the timing of oxygenation and how it relates to the evolution of life. This project will develop our understanding of how Earth has remained habitab ....The oxygenation of Earth’s early marine ecosystems. This project aims to map out the complex evolution of the Earth’s ocean ecosystems and oxygenation using marine carbonates. The oxygenation of Earth’s surface is one of the most profound processes to shape the planet, affecting all biological and geological systems. However, uncertainties remain in the timing of oxygenation and how it relates to the evolution of life. This project will develop our understanding of how Earth has remained habitable through significant intervals of environmental change. Using the geology of Australia, and elsewhere, this project is expected to derive the oxygenation evolution of ancient seawater and its effect on reef ecosystems during critical intervals of Earth’s history.Read moreRead less

The aim of this proposal is to establish a state-of-the-art research facility as part of a comprehensive material characterisation infrastructure required to support JCU's expanding activities in geology, oceanography, sustainable water research and nanotechnology. New instruments to measure attractive forces between particles, material density, porosity, surface area, and carbon, nitrogen, and sulphur content in conjunction with replacing an old grain size analyser will provide advanced instrumentation for research across several Schools with a diversity of research priorities. The proposed facility will create new opportunities for collaborative programs with national and international researchers as well as foster industry partnership.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
Testing the Australian Megatsunami Hypothesis. More than 300000 lives and property worth more than $150bn on the NSW coast are vulnerable to large tsunamis but at present we do not have a clear idea about how often such tsunamis occur and how big they might be. This project will identify and date evidence for past tsunamis on the coasts of NSW and west New Zealand which will help us understand regional tsunami risk. This will provide knowledge that will guide tsunami risk management practice in ....Testing the Australian Megatsunami Hypothesis.

The scientific innovation represented by this project will help Australian scientists to better understand an important part of the plate tectonic cycle. This project will be of direct relevance to the Australian minerals exploration industry and will provide better constraints on rift-related metallogenesis.Read moreRead less
Evolutionary dynamics in deep time: faunal turnover during the Ediacaran. This project aims to investigate the world’s oldest faunal succession in the fossil record by determining the presence and extent of a sedimentary gap and confirming the role of time in the control of fossil distribution.

This project aims to investigate the world’s oldest faunal succession in the fossil record by determining the presence and extent of a sedimentary gap and confirming the role of time in the control of fossil distribution. Significant breakthroughs and capacity building are expected in the areas of palaeontology, evolutionary biology and geology using a hitherto unrecognised hiatus in the rock succession. Project outcomes include enhanced understanding of the first animal communities on Earth – these should provide significant benefits, such as revealing Australia's unique record of oldest complex organisms, while bringing additional tourism to the region, and increasing the strength of the Flinders Ranges UNESCO World Heritage nomination.Read moreRead less

Most provenance analyses are based on single-grain analytical techniques that may miss vital information. This project will develop an integrated, systematic approach to provenance analysis by applying a broad range of modal, geochemical and isotopic techniques to enable the effective identification of sources of grains in sedimentary rocks. The new system will be used to test hypotheses of when the Pilbara and Yilgarn cratons amalgamated to form the core of the Australian continent.Read moreRead less
