Summary
Tracking the response of the Australian climate to abrupt climate change. This project will use cutting-edge climate proxy analyses to reconstruct the response of the Australian climate system to global climate change over the last 2,000 years. The results will provide significant insight in to how future global climate change will impact on social, biological and physical systems in Australia.
Cosmogenic isotopes in glacial landscapes: climate change and production rates. By dating glacial deposits near Australia, we will provide new insights into climate change in our region. A better understanding of the factors that control climate change in our region will be of benefit to all Australians. 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 reg ....Cosmogenic isotopes in glacial landscapes: climate change and production rates.

A better understanding of the factors that control climate change in our region will be of benefit to all Australians. 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
Looking back to see the future: Change in the Lambert Glacier and the East Antarctic Ice Sheet. To develop a comprehensive understanding of the Lambert Glacier of East Antarctica, from the time of the last maximum glaciation to the present, through an integrated and interdisciplinary study combining new field evidence - ice retreat history, geodetic measurements of crustal rebound, satellite measurements of present ice heights and changes therein - with other geological and glaciological data an ....Looking back to see the future: Change in the Lambert Glacier and the East Antarctic Ice Sheet. To develop a comprehensive understanding of the Lambert Glacier of East Antarctica, from the time of the last maximum glaciation to the present, through an integrated and interdisciplinary study combining new field evidence - ice retreat history, geodetic measurements of crustal rebound, satellite measurements of present ice heights and changes therein - with other geological and glaciological data and numerical geophysical modelling advances. The project contributes to the quantitative characterisation of the complex interactions between ice-sheets, oceans and solid earth within the climate system. Outcomes have implications for geophysics, glaciology, geomorphology, climate, and past and future sea-level change.Read moreRead less
Understanding global warming using long-term glacier retreat records. This project will determine the sensitivity of climate to future global warming, contributing to understanding one of the greatest problems facing humanity today. We will take an historic approach, determining the effects of the greatest global warming in Earth's recent history after the last ice age 20,000 years ago. By constructing well-dated, accurate records of glacier retreat at key locations, we will quantitatively estim ....Understanding global warming using long-term glacier retreat records. This project will determine the sensitivity of climate to future global warming, contributing to understanding one of the greatest problems facing humanity today. We will take an historic approach, determining the effects of the greatest global warming in Earth's recent history after the last ice age 20,000 years ago. By constructing well-dated, accurate records of glacier retreat at key locations, we will quantitatively estimate temperature change as the planet warmed. These findings will help us understand the future effects of global warming so that we are better prepared for the environmental and economic costs. Read moreRead less
Testing the hypothesis of synchronous inter-hemispheric climatic change during the Last Termination (20,000-10,000 years ago). 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 Australasi ....Testing the hypothesis of synchronous inter-hemispheric climatic change during the Last Termination (20,000-10,000 years ago).

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

Accurate timekeeping is central to the environmental and archaeological sciences. Radiocarbon dating is the leading geochronological technique for events of the past 50,000 years, but the issue for sample contamination remains a major source of concern. Avoidance of contaminants can be achieved through the identification of specific biomolecular compounds that unambiguously formed part of the original sample, and the isolation of these biomolecules for radiocarbon dating using accelerator mass spectrometry. Here we request funds to establish Australia's first compound-specific radiocarbon dating facility, to obtain ages of high accuracy for key studies of climate and landscape change, evolutionary biology and archaeology.Read moreRead less

This project aims to establish an environmental radioactivity research centre, equipped with ultra-low background and high-resolution alpha and gamma spectrometry systems, radon detectors and radium delayed coincidence counters. The centre will address a critical demand in Australia for precise analysis of a large suite of natural and artificial radionuclides, which will be used as tracers and chronological tools to investigate key questions in oceanography and the mining and energy, archaeological, agricultural, and forestry sectors. The facility is expected to substantially increase expertise and training in radionuclides in Australia, and promote high-level research collaborations and outputs of both national and international significance. Major outcomes of the proposed facility include better understanding of how oceans regulate climate and improved capacity to assess effects of radiation on natural ecosystems.Read moreRead less

Summary
A world-class rock magnetic facility to support Australian palaeomagnetic and environmental research. Magnetic properties of rocks and environmental particles provide information about a vast range of geological and environmental processes. We propose to develop a facility that will enable detection and interpretation of these magnetic signals to aid understanding of climate change, mineral exploration, and the geological development of Australia.

This project will model dating techniques across sites to identify a precise extinction window and compare behaviour and past environmental conditions to determine why the ape failed and man persevered. Outcomes will generate a new understanding of past environmental change as a driver of megafaunal extinction in comparison with human adaption and survival.Read moreRead less
