Palaeoclimate reconstructions from the isotopic signatures of fossilised leaf waxes. This project develops a method for using the chemical signature of fossilised leaf waxes to reconstruct hydrologic change in south-eastern Australia during the Holocene (last 10,000 years) and Eocene (56-34 million years ago). Understanding climate in the geologic past is essential for testing models and projecting future climate with rising carbon dioxide.
Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed ....Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed knowledge of how changes in fire and rain shaped the ecology and evolution of plants and animals. This knowledge is key to understanding how Australian ecosystems function and to protecting their cultural, economic and environmental values, especially as climate and fire regimes continue to change into the future.Read moreRead less
Carbon sequestration by mineral surface area as a feedback to climate warming in a greenhouse ocean. The project will investigate a previously unrecognised negative feedback to global warming resulting from sequestration of carbon to marine sediments by soil-formed clay minerals. By studying the past transitions to greenhouse periods, this project will assess the likely influence of this feedback in the present transition to a warmer climate.
Testing the mechanisms and effects of abrupt and extreme climate change. This project aims to resolve the timing, rate of change, mechanisms and effects of past abrupt and extreme global climate change. These are uncertain for abrupt and extreme warming events in the recent geological record, due to difficulties comparing terrestrial and marine palaeoclimate and faunal records on radiocarbon timescales with independently dated ice cores over the last 50,000 years. By using yearly-resolved tree r ....Testing the mechanisms and effects of abrupt and extreme climate change. This project aims to resolve the timing, rate of change, mechanisms and effects of past abrupt and extreme global climate change. These are uncertain for abrupt and extreme warming events in the recent geological record, due to difficulties comparing terrestrial and marine palaeoclimate and faunal records on radiocarbon timescales with independently dated ice cores over the last 50,000 years. By using yearly-resolved tree ring records, the project will discover when, how and what effect abrupt and extreme change had on global climate and species/ecosystems.Read moreRead less
Were abrupt changes in the Precambrian global carbon cycle the trigger for animal appearance and radiation on Earth? The origin of complex life and the properties that allow that life to be sustained on this planet are recorded within the geologic record. This project will reveal the role that severe perturbations of the global carbon cycle and climate had in triggering the step-wise change to animal life after billions of years of only single cell organisms.

Summary
Sonic drilling to provide contamination-free core sampling of rock and unconsolidated sediment. Australia is the world's driest inhabited continent. Understanding environmental and climatic changes, from the temperate period when humans arrived about 50,000 years ago to the present state of widespread aridity, is crucial for modelling future climate change. This facility will provide new generation drilling equipment which is necessary to obtain accurate records.

This proposal is for an 18-month membership of the International Ocean Discovery Program (IODP), the world’s largest collaborative research program in Earth and Ocean sciences. The Program studies the history and current activity of the Earth by conducting seagoing coring expeditions and monitoring of instrumented boreholes, using globally unique infrastructure that Australians would otherwise have no access to. Program outcomes include understanding past global environmental change on multiple time scales, the deep biosphere, plate tectonics, formation and distribution of resources, and generation of hazards. These outcomes are paramount to Australia’s national science and research priorities, and societal and economic prosperity.Read moreRead less
Past trends and future risk of climate extremes in southern Australia. Prolonged droughts and periods of heightened flood and fire risk present a major challenge for Australia’s society and economy. This proposal aims to better resolve the causes and risks of decadal climate extremes through a suite of high quality records of temperature, rainfall/evaporation and humidity in southern Australia over 2000 years. Novel geochemical analyses will be developed and applied to lake sediments – method de ....Past trends and future risk of climate extremes in southern Australia. Prolonged droughts and periods of heightened flood and fire risk present a major challenge for Australia’s society and economy. This proposal aims to better resolve the causes and risks of decadal climate extremes through a suite of high quality records of temperature, rainfall/evaporation and humidity in southern Australia over 2000 years. Novel geochemical analyses will be developed and applied to lake sediments – method development which is likely to benefit climate, minerals and biosecurity research. New knowledge of mechanisms underlying climate variability is expected to benefit fundamental research, while future-facing models will allow land managers and policy makers to better anticipate extraordinary climate events.Read moreRead less

This project is for a 5-year membership of the International Ocean Discovery Program, the world’s largest collaborative research program in earth and ocean sciences addressing international priorities. The program conducts seagoing coring expeditions and monitoring of instrumented boreholes to study the history and current activity of the Earth, recorded in sediments and rocks below the seafloor. The program’s aims include understanding past global environments on multiple time scales, the deep biosphere, plate tectonics, occurrence and distribution of resources, and generation of hazards. Several multinational expeditions are scheduled and planned in our marine jurisdiction and within the Australasian region. Read moreRead less
