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. Atmospheric conditions propit ....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. 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
Predicting pollutant dispersion within the CBD. The accidental or pre-meditated release of hazardous gases and aerosols within an urban environment are potentially threatening to human life and safety. Emergency responders require adequate information to quickly address these concerns yet the lack of detailed observations and the complex nature of the dispersion make this task difficult.

The accidental or pre-meditated release of hazardous gases and aerosols within an urban environment are potentially threatening to human life and safety. Emergency responders require adequate information to quickly address these concerns yet the lack of detailed observations and the complex nature of the dispersion make this task difficult. This project will collect detailed observations of tracer dispersion within the Perth central business district and combine these observations with multiscale modelling to redefine appropriate emergency response models as well as their limits. Such analysis will enhance mitigation strategies.Read moreRead less
