Marine oil seeps and airborne particulates characterisation for organic compositional fingerprinting by using novel gas chromatographic technologies. Comprehensive two-dimensional gas chromatography (GCxGC) is a powerful new tool for studying complex organic materials. The technique provides a highly sensitive method of fingerprinting not only the composition of the material but also its environmental history and behaviour.

Comprehensive two-dimensional gas chromatography (GCxGC) is a powerful new tool for studying complex organic materials. The technique provides a highly sensitive method of fingerprinting not only the composition of the material but also its environmental history and behaviour. In this project the technique will be applied to a range of petroleum-related organic samples, including oil seeps from the ocean floor, and airborne particulates contributing to air pollution. The research will lead to a better understanding of geochemistry of petroleum-related materials and their potential impact on the environment and on public health.Read moreRead less

The socio-economic benefits to Australia from the project include (i) a novel holistic modelling tool to building design that maximises indoor comfort and provides acceptable air quality for the inhabitants whilst minimising energy usage in transit oriented urban developments; and (ii) estimation of energy consumption for different building designs and operation with respect to air quality and thermal comfort. The ultimate economic benefit of this research will be a reduction in health care costs and lost productivity as well as reduction of energy used and associated emissions. The research will also place Australia in the forefront of international progress and the race towards better methods for achieving environmental sustainability.Read moreRead less

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
Physical, Chemical and Radiative Characteristics of Australian Continental Aerosols. Australian desert dust, and the biomass burning aerosol particles produced in the top-end burning season, have the potential to impose an environmental burden not only on Australia, but also on the surrounding region. While most of the world's major aerosol types have been well studied in recent years, these two remain largely unknown. There are good reasons to believe that Australian aerosols are different from ....Physical, Chemical and Radiative Characteristics of Australian Continental Aerosols. Australian desert dust, and the biomass burning aerosol particles produced in the top-end burning season, have the potential to impose an environmental burden not only on Australia, but also on the surrounding region. While most of the world's major aerosol types have been well studied in recent years, these two remain largely unknown. There are good reasons to believe that Australian aerosols are different from many others. We therefore intend to fully characterize their relevant properties, so we may monitor them from space, and evaluate their environmental impacts.Read moreRead less
The best astronomical site on earth? A modern optical/infrared telescope is only as good as its site. We have previously shown that the infrared skies above the South Pole are up to 100 times darker than skies elsewhere, leading to enormous potential gains in sensitivity. We now seek to extend these measurements to Antarctic sites that are even higher, drier and colder than the South Pole. These are expected to be the best observing sites on Earth, paving the way for the deployment of telescop ....The best astronomical site on earth?

We now seek to extend these measurements to Antarctic sites that are even higher, drier and colder than the South Pole.

Anomalous isotope effects in atmospheric ozone and carbon dioxide. The anomalous isotopic composition of atmospheric ozone, which has been a puzzle for over twenty years, will be investigated by laboratory and atmospheric measurements. An understanding of the source of this anomaly and its effect on the isotopic composition of other trace atmospheric gases, especially CO2, would provide unique opportunities for constraining the tropospheric and stratospheric ozone budgets and determining the his ....Anomalous isotope effects in atmospheric ozone and carbon dioxide. The anomalous isotopic composition of atmospheric ozone, which has been a puzzle for over twenty years, will be investigated by laboratory and atmospheric measurements. An understanding of the source of this anomaly and its effect on the isotopic composition of other trace atmospheric gases, especially CO2, would provide unique opportunities for constraining the tropospheric and stratospheric ozone budgets and determining the history of a particular air mass. The method of detection will be high resolution FTIR spectroscopy which, in contrast to traditional mass-spectrometric methods, provides information about the position of the heavy atom in an enriched ozone molecule and requires no sample preparation.Read moreRead less

QUANTIFICATION OF INTERACTIONS DURING THE DISPERSION OF CORONA IONS AND AIRBORNE PARTICLES NEAR POWER LINES. Currently there is no method for quantification of concentration and dispersion of charged aerosols near high voltage power lines (HVPLs). However, hypothesis have been presented, but not yet proven scientifically, that residents of houses close to combustion sources such as highways or industrial plants and HVPLs may be subjected to health risk due to inhalation of charged aerosols.

Currently there is no method for quantification of concentration and dispersion of charged aerosols near high voltage power lines (HVPLs). However, hypothesis have been presented, but not yet proven scientifically, that residents of houses close to combustion sources such as highways or industrial plants and HVPLs may be subjected to health risk due to inhalation of charged aerosols. The outcome of this project will be a model for quantitative assessment of the processes occurring during the transport and dispersion of corona ions and combustion aerosol, which will be a tool for predictive risk assessment and informed management of public resources in relation to power line design and maintenance.Read moreRead less
