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 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

This facility will enable researchers to obtain high-resolution geochemical profiles in the study of environmental change and climate variability. It will provide archive data on the variation of density and chemical element composition along sediment and soil cores, rock cores, wood samples, speleothems and corals. These archives contain important information such as human activity, climate variability, water quality changes, pollution histories, recent geomorphological change, land-use change, introduction of invasive species and the occurrence of bushfires. A better understanding of the occurrence and timing of these major environmental issues is of national and regional importance.Read moreRead less

We will use a tool called exposure dating that has become very important in understanding a variety of processes at the Earth's surface, many of which are poorly understood in the Australian region. Our research will ensure that Australia remains at the leading edge of the application of this technique and is included in future international research programs. Read moreRead less

The results generated in this project will provide a greater understanding of the sensitivity of the Australasian region to a range of different climatic conditions (far beyond that recorded in historical datasets).

Focussing on climate at the end of the last ice age (20,000-10,000 years ago) we will investigate the timing, rate and magnitude of change in the Australasian region and test whether the variability was in phase with other records from the mid- and high-latitudes of the Southern and Northern Hemisphere. The results will provide a considerably improved context for understanding present and future climate change in Australia. Read moreRead less

This will lead to fundamental insights into the past and present-day mass-balance changes of the Antarctic
ice sheet. This research will provide critical data on the changes in the Antarctic ice sheet, a region where scientific information is currently poorly defined or lacking altogther. Combined with other geophysical data, the results of this project will produce, for the first time, constraints on the contribution of Antarctica to global ice and sea-level models.

We will build a stable isotope ion microprobe (SHRIMP SI) to examine extraterrestrial and terrestrial systems in unprecedented detail. In terrestrial applications, the main issue is accuracy at the 0.01 percent level for 20-micron spots, which we can apply to studies of development of life on Earth, climatic records, weathering, and formation of ore bodies. Sample return missions of solar wind and comets will provide unique samples related to the formation of our solar system.Read moreRead less

Much of the Australian landscape is subject to a dry and evaporative climate, making it very difficult to use conventional geochemical techniques to estimate past temperatures, even on short timescales of tens to hundreds of years. The application of a new isotopic technique to preserved carbonate minerals (soil carbonate, shells in rivers, lakes and the ocean) avoids the difficulty of this variable evaporation, and directly measures past temperatures. This will have a profound effect on our understanding of environmental changes on both short and long time scales, and permit a better understanding of the hydrological balances within the landscape.Read moreRead less
