The Australian Dust Transport System: characterisation and downwind impacts. Most Australians are aware that dust storms occur in dry inland areas and recently many experienced first hand, the dust storms that engulfed our cities. Few, however, are aware of the diverse impacts of desert dust downwind from source. Recent technological advances in remote sensing have made dust storms much easier to study, and Australian researchers will use these, and other innovative techniques, to reconstruct th ....The Australian Dust Transport System: characterisation and downwind impacts. Most Australians are aware that dust storms occur in dry inland areas and recently many experienced first hand, the dust storms that engulfed our cities. Few, however, are aware of the diverse impacts of desert dust downwind from source. Recent technological advances in remote sensing have made dust storms much easier to study, and Australian researchers will use these, and other innovative techniques, to reconstruct the major dust storms back to 1960. They will reconstruct the sources, dust loads and trajectories of these storms, and examine how dust affects urban air pollution. Their data will also be provided to an allied research team in New Zealand, who are examining how iron-rich Australia dust affects phytoplankton in the oceans.Read moreRead less
Vulnerability of the Murray-Darling basin hydrometeorology to human modification. The Murray-Darling Basin (MDB) provides 40 per cent of Australia's agricultural production. Some 1,500,000 hectares use irrigation for agriculture and year-to-year variations in productivity highlights a basin that is vulnerable to changes resulting from human activity. This proposal builds an integrated modelling system of the MDB to understand its hydrology and meteorology in the context of human modification to ....Vulnerability of the Murray-Darling basin hydrometeorology to human modification. The Murray-Darling Basin (MDB) provides 40 per cent of Australia's agricultural production. Some 1,500,000 hectares use irrigation for agriculture and year-to-year variations in productivity highlights a basin that is vulnerable to changes resulting from human activity. This proposal builds an integrated modelling system of the MDB to understand its hydrology and meteorology in the context of human modification to climate and to land use in the basin. The improved understanding of the MDB will allow science-aware policy developments that reduce the vulnerability of agriculture and water resources within the basin to future changes caused through human activity.Read moreRead less
Interactions between sulfur, nitrogen, and iron cycles in the sustainable management and use of acid sulfate soils. Acid Sulfate Soils (ASS) can cause major land management and environmental problems. It has been proposed that the linkages between the Sulfur, Nitrogen, and Iron biogeochemical cycles deterrmine the environmental and crop production hazards associated with use of ASS. In order to develop best management practices for ASS, it is important to research those linkages and determine th ....Interactions between sulfur, nitrogen, and iron cycles in the sustainable management and use of acid sulfate soils. Acid Sulfate Soils (ASS) can cause major land management and environmental problems. It has been proposed that the linkages between the Sulfur, Nitrogen, and Iron biogeochemical cycles deterrmine the environmental and crop production hazards associated with use of ASS. In order to develop best management practices for ASS, it is important to research those linkages and determine their contribution to fluxes of materials exported from these soils. This project will carry out that research and will transfer results to industry partners to improve land management practices and identify appropriate landuses in ASS landcapes.Read moreRead less
