The composition and transport of Australian air-borne dust: critical to continental and marine environments. This project will determine the composition of Australian airborne dust and effects on the environment and in particular soils, rainforests and the marine realm, including reefs. 'Fingerprinting' the chemical and microbiological content of aeolian dust is of particular relevance to determining its impact on the health of the Australian people and environment.

This project will determine the composition of Australian airborne dust and effects on the environment and in particular soils, rainforests and the marine realm, including reefs. 'Fingerprinting' the chemical and microbiological content of aeolian dust is of particular relevance to determining its impact on the health of the Australian people and environment. Atmospheric conditions propitious for dust entrainment and transport will be determined, and in particular atmospheric exchanges between Indonesia, southern Africa and Australia will be established. The relevance of aeolian dust to climate, ecosystems and biosecurity in our region will be established through the study of marine and lacustrine cores.Read moreRead less
WAKE FLOWS WITH UPSTREAM TURBULENCE IN MARINE, ATMOSPHERIC AND BUILT ENVIRONMENTS. Through improved understanding of turbulent wakes the project will have applications across aeronautics and hydrodynamics, leading to more efficient engineering designs to reduce flow drag. In marine environments our findings will improve coastal ocean models and the prediction of pollutant dispersal, nutrient fluxes and sediment transport, and contribute to the management of biological productivity (NRP 1.5).

Through improved understanding of turbulent wakes the project will have applications across aeronautics and hydrodynamics, leading to more efficient engineering designs to reduce flow drag. In marine environments our findings will improve coastal ocean models and the prediction of pollutant dispersal, nutrient fluxes and sediment transport, and contribute to the management of biological productivity (NRP 1.5). In the atmospheric boundary layer, the results will assist planners to improve wind environments near large buildings or clusters of buildings, benefiting the safety of aircraft at takeoff and landing. The project will develop collaboration and help maintain the strength of Australian research in environmental flows.Read moreRead less
