This project aims to develop a numerical circulation model applicable to fringing reef systems, in particular, the Ningaloo reef, Western Australia. The model will include the effects of tides, winds, surface gravity waves and density. The model results will be compared to field measurements collected by the Australian Institute of Marine Science. After the model has been developed and validated, it will be used to investigate processes such as water exchange between lagoons and open sea, effects of contaminant spills and recruitment within the reef systems. An understanding of these processes is essential for the sustainable management of these systems.Read moreRead less
Improving biological nitrogen removal by enhanced mixing in non-aerated bioreactors. Mixing has been identified as a key factor in achieving enhanced performance out of existing and upgraded bioreactors. There is currently a poor understanding of the relationship between non-ideal flow and performance in wastewater treatment bioreactors. The project will determine this relationship and subsequently use it to show how reactor performance can be improved, providing first criteria by which mixing c ....Improving biological nitrogen removal by enhanced mixing in non-aerated bioreactors.

There is currently a poor understanding of the relationship between non-ideal flow and performance in wastewater treatment bioreactors. The project will determine this relationship and subsequently use it to show how reactor performance can be improved, providing first criteria by which mixing can be assessed, and second a systematic methodology for improving reactor performance by improving mixing.Read moreRead less

Summary
A laser optical plankton counter for laboratory and in-situ size distributions of zooplankton, to assess the basis and outcomes of changing ecosystems. The researchers will integrate studies of zooplankton biodiversity from the tropics to the Southern Ocean with an optical plankton counter to quickly measure zooplankton size and approximate shape. This new technology, together with a resurgence in collaborative marine science through the Integrated Marine Observing System and the Sydney Institut ....A laser optical plankton counter for laboratory and in-situ size distributions of zooplankton, to assess the basis and outcomes of changing ecosystems. The researchers will integrate studies of zooplankton biodiversity from the tropics to the Southern Ocean with an optical plankton counter to quickly measure zooplankton size and approximate shape. This new technology, together with a resurgence in collaborative marine science through the Integrated Marine Observing System and the Sydney Institute of Marine Science, will enable Australian researchers to understand changes in the plankton in freshwater or in estuaries, as well as in the East Australian Current. This current has already strengthened and is predicted to be the area of greatest warming in the Southern Hemisphere. The response of plankton communities to these changes will have profound effects on Australian fisheries and livelihoods.Read moreRead less
Trophic associations involving fish and crustaceans in coastal saltmarsh. Coastal saltmarsh is an endangered ecological community utilised by a diverse assemblage of fish during spring tides. Little attempt has been made to determine why fish visit saltmarsh, or what contribution saltmarsh makes to the diet of fish. This study combines gut analysis with novel approaches involving stable isotopes and radioactive markers to determine trophic interactions between fish and permanent members of the s ....Trophic associations involving fish and crustaceans in coastal saltmarsh. Coastal saltmarsh is an endangered ecological community utilised by a diverse assemblage of fish during spring tides. Little attempt has been made to determine why fish visit saltmarsh, or what contribution saltmarsh makes to the diet of fish. This study combines gut analysis with novel approaches involving stable isotopes and radioactive markers to determine trophic interactions between fish and permanent members of the saltmarsh fauna and flora. The project will provide coastal resource managers with quantifiable indicators of the relative significance of different saltmarsh communities to estuarine fisheries.Read moreRead less
Elicitation and Integration of Expert Information for Natural Resource Management with a Focus on Water. Australia's natural resource management requires integrating information from many sources, including survey data and community and expert opinion. We aim to develop statistical methods to formally combine this information and apply them to better management of our crucial resource, water.

Australia's natural resource management requires integrating information from many sources, including survey data and community and expert opinion. We aim to develop statistical methods to formally combine this information and apply them to better management of our crucial resource, water. The project contributes significantly to Australia's international obligations, and government agency and regional group science-based decision-making.
Outcomes include increased fundamental knowledge in statistics, technology transfer and improved decision-making capacity for natural resource management.
The project builds on strong existing collaborations between academic and industry partners and provides foundation for future funded projects.

Development of an adaptive statistical model for oceanic flooding hazards along the East Australian coast. Planning of invaluable coastal infrastructure and housing is critical to the economic and social well-being of Australian communities. Devastating flooding along coasts and estuaries in Australia frequently occurred before 1980, but has been less common since. However, the risks are clear and enormous as demonstrated in recent disasters like Hurricane Katrina and the 2004 Boxing Day tsunami ....Development of an adaptive statistical model for oceanic flooding hazards along the East Australian coast. Planning of invaluable coastal infrastructure and housing is critical to the economic and social well-being of Australian communities. Devastating flooding along coasts and estuaries in Australia frequently occurred before 1980, but has been less common since. However, the risks are clear and enormous as demonstrated in recent disasters like Hurricane Katrina and the 2004 Boxing Day tsunami. Climate change makes flood predictions even more difficult. This project will develop a new adaptive model which accounts for both the present and future climate and also regional variability. The research will be in collaboration with the NSW Dept of Climate Change to enable rapid government action to improve community trust in flood protection. Read moreRead less
Nitrous oxide and methane emissions from South East Queensland waterways and influence of wastewater discharges. Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors.

Climate change caused by greenhouse gas emissions is one of the most serious challenges facing mankind. Substantial emission reduction must be achieved, with responsibilities to be shared by all sectors. Rivers, estuaries and water storages contribute considerably to global nitrous oxide and methane emissions, much of which is anthropogenic contributed by urban and agricultural run-off and wastewater discharges. Through an in-depth study on several rivers, estuaries and reservoirs in South East Queensland, this project will provide data to enable reliable estimation of such emissions in Australia, and deliver knowledge and tool support for the development of strategic catchment management strategies.Read moreRead less
