The protracted drought across Australia and Boxing Day 2004 earthquake in Sumatra defied prediction, and are causing incalculable environmental, economic, and social harm. Knowledge of past climate extremes will enhance our ability to predict climate change, and alleviate adverse affects for Australasian nations who miss-out in the future redistribution of life-giving moisture. Insights into the great-earthquake cycle will help fulfil Australia's responsibility to predict tsunamis, for the benefit of nations fringing Australasian seismotectonic zones. Development of improved techniques in palaeoclimatology, palaeoclimate modelling, and palaeoseismology will provide new collaborations and opportunities for research, training, and education.Read moreRead less
Quantifying the El Niño-Indian Ocean Dipole system using high-resolution coral palaeoclimate archives. The ocean surrounding Indonesia is the warmest on Earth and a major source of energy for global atmospheric circulation. Understanding the role of the Warm Pool in future climate change is of key importance, but highly controversial because the potential extent of its variability is largely unknown. To address this issue, this project will provide the first major geochemical investigation of ....Quantifying the El Niño-Indian Ocean Dipole system using high-resolution coral palaeoclimate archives. The ocean surrounding Indonesia is the warmest on Earth and a major source of energy for global atmospheric circulation. Understanding the role of the Warm Pool in future climate change is of key importance, but highly controversial because the potential extent of its variability is largely unknown. To address this issue, this project will provide the first major geochemical investigation of recently discovered ancient corals in Indonesia using state-of-the-art microanalytical techniques. Outcomes from these palaeoclimate records will advance our understanding of global climate change, rainfall variability related to the El Nino - Indian Ocean Dipole system, and Australian drought.Read moreRead less
Reengineering a dynamic vegetation model to explore the stability of Australian terrestrial carbon. Overseas models do not represent Australian biophysical processes well: our flora and fauna are unique and our soils are old and nutrient poor. In contrast, the National Carbon Accounting System (NCAS) is a world-class framework for estimating current carbon processes. By building NCAS expertise into an overseas model of soil and vegetation processes we can develop the capacity to increase our con ....Reengineering a dynamic vegetation model to explore the stability of Australian terrestrial carbon. Overseas models do not represent Australian biophysical processes well: our flora and fauna are unique and our soils are old and nutrient poor. In contrast, the National Carbon Accounting System (NCAS) is a world-class framework for estimating current carbon processes. By building NCAS expertise into an overseas model of soil and vegetation processes we can develop the capacity to increase our confidence in future projections of carbon and vegetation change. Our proposal, linking Universities, CSIRO and the Australian Greenhouse Office establishes a team that is internationally competitive. It will enhance local expertise and local model development to ensure national policy development is underpinned by world-class science.Read moreRead less

Causes of Enhanced Warming of the Southern Ocean. The Southern Ocean is critical to the global climate system in general, and Australian climate in particular. However, the Southern Ocean is poorly understood, poorly observed and poorly modelled by global climate models. The response of the Southern Ocean to increases in wind forcing (due to the ozone hole and global warming) will be examined. Climate impacts such as Australian rainfall trends, potential instability of the West Antarctic Ice She ....Causes of Enhanced Warming of the Southern Ocean. The Southern Ocean is critical to the global climate system in general, and Australian climate in particular. However, the Southern Ocean is poorly understood, poorly observed and poorly modelled by global climate models. The response of the Southern Ocean to increases in wind forcing (due to the ozone hole and global warming) will be examined. Climate impacts such as Australian rainfall trends, potential instability of the West Antarctic Ice Sheet and changes to the global overturning circulation will be quantified. Understanding these impacts will help to manage Australia's water resources and to predict the future Southern Ocean circulation.Read moreRead less
Growth and Decay of ice sheets during glacial cycles:the example of Europe. The proposal is to develop a comprehensive model for the growth and decay of the ice sheets of Europe during the last glacial cycle, using a combination of diverse field evidence with geophysical modelling. The outcomes provide boundary conditions for climate models (times of inception and decay, ice limits, ice thickness) including processes driving climate as well as constraints on the Earth's mantle viscosity.

The proposal is to develop a comprehensive model for the growth and decay of the ice sheets of Europe during the last glacial cycle, using a combination of diverse field evidence with geophysical modelling. The outcomes provide boundary conditions for climate models (times of inception and decay, ice limits, ice thickness) including processes driving climate as well as constraints on the Earth's mantle viscosity. Thus the project contributes to the quantitative characterisation of both climate change and planetary structure. In an Australian context, these outcomes form important elements in the development of predictive models for sea-level change.Read moreRead less
