This project will contribute to maintaining Australian scholars at the forefront of innovative research in Southeast Asia. The project will contribute to a more nuanced understanding of attitudes towards the environment within the region. Australia has a significant aid investment in the region and this is likely to grow as a result of the White Paper on overseas development aid. In Southeast Asia much of the aid effort addresses issues of sustainable resource management. Australian businesses have also indicated that deeper insights into local perspectives on sustainability and resource management will be useful in enhancing economic cooperation.Read moreRead less

Summary
Instrumentation for combined seismic and electromagnetic Earth sounding. The set of geophysical recorders will provide the means to enhance understanding of the structure of the Australian continent in 3-D. The interpretation of multiple images of Earth structure will help to link features in the crust and mantle beneath, and provide controls on the evolution and assembly of the present continent, with a major contribution to possible geotransects as recommended in the 2003 National Strategic Pl ....Instrumentation for combined seismic and electromagnetic Earth sounding. The set of geophysical recorders will provide the means to enhance understanding of the structure of the Australian continent in 3-D. The interpretation of multiple images of Earth structure will help to link features in the crust and mantle beneath, and provide controls on the evolution and assembly of the present continent, with a major contribution to possible geotransects as recommended in the 2003 National Strategic Plan for the Geosciences. Combining seismic and electromagnetic methods will provide both geochemeical and geophysical constaints, e.g., on zones of alteration and shear with the potential for deep mineralisation.

What limits CO2 diffusion inside leaves? Dissecting the diffusion path with Arabidopsis mutants. Human induced increase in atmospheric carbon dioxide is now generally accepted as contributing to global warming. Forecasting our future impact relies on models of terrestrial photosynthesis which use a signature in the atmosphere created by plants when they discriminate against the heavy stable isotope of carbon during photosynthesis. Discrimination between isotopes is affected by carbon dioxide dif ....What limits CO2 diffusion inside leaves? Dissecting the diffusion path with Arabidopsis mutants. Human induced increase in atmospheric carbon dioxide is now generally accepted as contributing to global warming. Forecasting our future impact relies on models of terrestrial photosynthesis which use a signature in the atmosphere created by plants when they discriminate against the heavy stable isotope of carbon during photosynthesis. Discrimination between isotopes is affected by carbon dioxide diffusion within leaves and key steps in this process will be identified through the use of Arabidopsis mutants. Better representation of this process in models will improve estimates of terrestrial photosynthesis and climate change forecastsRead moreRead less
Relationship between subduction zone geometry, trench kinematics and great subduction earthquakes. The devastating Boxing Day 2004 earthquake near Sumatra and the four other largest earthquakes in recorded history all occurred along subduction zones. This research will compare the geodynamic setting of these subduction zones with those surrounding the Australian continent and assess whether the Australian subduction zones are capable of producing great earthquakes and tsunamis that might pose a ....Relationship between subduction zone geometry, trench kinematics and great subduction earthquakes. The devastating Boxing Day 2004 earthquake near Sumatra and the four other largest earthquakes in recorded history all occurred along subduction zones. This research will compare the geodynamic setting of these subduction zones with those surrounding the Australian continent and assess whether the Australian subduction zones are capable of producing great earthquakes and tsunamis that might pose a risk for the east and northwest coast of Australia. Also, Eastern Australia is a composite of fossil arcs rich in ore deposits and the Tasman Sea region is composed of basins that host hydrocarbons, all of which formed by subduction processes. The proposed research will thus improve the basis for mineral and hydrocarbon exploration.Read moreRead less
Environmental stability of nanoscale materials for catalysis and sensing. After two decades of research, the first wave of 'nanotechnology' consumer products are entering the market, and large quantities of nanoparticles (less than millionth of a centimetre in size) are now being produced annually. However, before any new product can be manufactured, we need to know how stable engineered nanomaterials are before we bring them into our home, or we find them (unintentionally) free in our waterways ....Environmental stability of nanoscale materials for catalysis and sensing. After two decades of research, the first wave of 'nanotechnology' consumer products are entering the market, and large quantities of nanoparticles (less than millionth of a centimetre in size) are now being produced annually. However, before any new product can be manufactured, we need to know how stable engineered nanomaterials are before we bring them into our home, or we find them (unintentionally) free in our waterways and other ecosystems. For the first time, this project uses high performance supercomputing and advanced theoretical modelling to predict the stability of nanomaterials under a wide range of environmental conditions, to help safe guard Australia from potential 'nano-hazards' associated with these tiny pieces of matter.Read moreRead less
Nature and Nation: Science, Environment and National Identity in Australia. Nature and Nation combines interviews and archival research to explore the intersection of three worlds in Australia:
· the natural world
· the scientific world that speaks for nature in settler society, and
· the cultural world that fosters and constrains science and other ways of knowing about nature.
The primary focus is the workings of science in northern Australia, where the frontier has never closed. The a ....Nature and Nation: Science, Environment and National Identity in Australia. Nature and Nation combines interviews and archival research to explore the intersection of three worlds in Australia:
· the natural world
· the scientific world that speaks for nature in settler society, and
· the cultural world that fosters and constrains science and other ways of knowing about nature.
The primary focus is the workings of science in northern Australia, where the frontier has never closed. The aim is to elucidate the past, present and future roles of environment and science in Australia's nation-building. Outcomes will include public lectures, journal articles and a major book for a general audience.

Do terrestrial processes intensify Australian droughts ? Australia's agricultural productivity is strongly affected by climate, climate variability and climate change. Recent climate changes in Western Australia forced adaptation strategies costing $500 million while the anomalously intense 2002 Murray-Darling Basin drought significantly affected agriculture. Any further intensification of droughts would affect Australia's rural economy. This proposal will assess the role of terrestrial processe ....Do terrestrial processes intensify Australian droughts ? Australia's agricultural productivity is strongly affected by climate, climate variability and climate change. Recent climate changes in Western Australia forced adaptation strategies costing $500 million while the anomalously intense 2002 Murray-Darling Basin drought significantly affected agriculture. Any further intensification of droughts would affect Australia's rural economy. This proposal will assess the role of terrestrial processes, linked to increasing CO2, in causing the drought intensification and declines in rainfall. This will provide knowledge that will guide the development of future environmental management strategies.Read moreRead less
The human elements: a cultural history of Australian weather. This project will study the experience of weather in Australia from the 1880s to the 1980s. Drawing upon environmental history, history of science and cultural history, we aim to go beyond a catalogue of weather events or climatic obsessions, to explore how the meanings of weather and climate are themselves constructed through the interaction of science, nature and society.

Development and application of the Uranium-series method for dating ancient rock engravings. Radiocarbon dating has been used to establish the age of relatively recent Australian rock art, but the ages of ancient engravings cannot be measured beyond the limit of this method. Comparative radiocarbon and uranium-series assays will be made on pairs of test samples collected from natural mineral deposits at engraving locations constrained by the ages of lakes, lava flows, sedimentary deposits or ic ....Development and application of the Uranium-series method for dating ancient rock engravings. Radiocarbon dating has been used to establish the age of relatively recent Australian rock art, but the ages of ancient engravings cannot be measured beyond the limit of this method. Comparative radiocarbon and uranium-series assays will be made on pairs of test samples collected from natural mineral deposits at engraving locations constrained by the ages of lakes, lava flows, sedimentary deposits or ice. Using test samples with independent and radiocarbon age controls will give confidence in the uranium dating approach for reliably measuring the ages of similar coatings associated with ancient carvings and exposed rock surfaces throughout the world.Read moreRead less
