Reconstructing changes in atmospheric circulation over the mid-latitudes of the Southern Hemisphere during the past 3000 years. The climate of the mid-latitudes of the southern hemisphere is of global significance and yet past changes have proved difficult to reconstruct due to the dearth of records. Working across the Southern Ocean region using tree rings, lake sediments and ice cores, the project will produce the first comprehensive reconstruction spanning the last 3000 years.

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

Isotope analyser with delta17O capability to examine water fluxes. Isotope analyser with delta-17-O capability to examine water fluxes: This project aims to investigate a range of processes, including quantifying evaporative losses, moisture recycling, groundwater-surface water interactions, and records of past climate in ice cores using novel capabilities for continuous measurement of triple oxygen isotopes (16-O, 17-O, 18-O) in water vapour.

Isotope analyser with delta-17-O capability to examine water fluxes: This project aims to investigate a range of processes, including quantifying evaporative losses, moisture recycling, groundwater-surface water interactions, and records of past climate in ice cores using novel capabilities for continuous measurement of triple oxygen isotopes (16-O, 17-O, 18-O) in water vapour. Enhanced understanding of water cycles is critical for understanding the discrete changes occurring in water regimes under changing climates and land use to efficiently manage our limited freshwater resources. The instrumentation is intended to put Australia at the forefront of new and emerging research in d17O analysis of water, an area that has potential to greatly improve our understanding of the water cycle within arid climates including Antarctica.Read moreRead less

Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We wil ....Resolving the role of kelp in blue carbon cycles to enable management. We aim to uncover how kelp forests contribute to carbon storage, biodiversity enhancement and nutrient mitigation in Australia. We will combine mapping and modelling to identify local variation in kelp carbon stocks and sequestration potential and verify kelp carbon export to deep ocean sinks through genetic tracing in seawater and sediments. Co-benefits will be identified through nutrient experiments and reef surveys. We will also assess the risk that calcification and production of halogenic gas within the kelp forest could offset its climate mitigation potential. Project outcomes will enable management to consider kelp ecosystem services broadly and optimize our capacity to meet current emission reduction and biodiversity commitments.Read moreRead less

This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Australia, the project will extend hydroclimatic records by several centuries, to identify the frequency and extent of extreme droughts across the continent. Outcomes are expected to provide appropriate context for evaluating and adapting to climate change, allowing climate modellers, agricultural producers and other industries to improve forecasts of likely change for risk management.Read moreRead less
Australian savannah landscapes: past, present and future. Australian savannahs are productive and culturally and biologically significant landscapes but are vulnerable to climate change. The project will determine savannah function (carbon and water balance) for the present and assess how sensitive they have been to past climate variability. The project will then address how they may respond to future climate change.
The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway?

We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which sex genes are targets? Epigenetic enzymes are astonishingly conserved, providing exciting opportunities to draw from human systems to unravel novel signatures of temperature-induced sex switching in reptiles. This project will advance knowledge of developmental programming generally.Read moreRead less
