A shared mass spectrometer with compound-specific capabilities to support innovative research in biology, the environment and geology: Stable isotope studies have huge and increasing relevance to environmental studies, many of which form the backbone of understanding Australia's terrestrial and marine systems. Compound-specific isotope analysis yields much more information than is available through bulk methods. The problem has been that the separations were labour-intensive and employed complex wet chemistry. New methods reduce the work-load enough to make compound-specific studies possible. In the case of carbon isotopes, new liquid chromatographic technology removes the need for derivatisations which dilute the natural signal and can render it unusable.Read moreRead less
Adaptive management of arid and semi-arid ecosystems. Australia’s arid zones contain some of the world’s most threatened ecosystems. Management must begin immediately, but our understanding of these fragile species and ecosystems is currently very limited. This project will develop and apply new research in Adaptive Management (“learning by doing”) to ensure the persistence of these rare places.
Integrating remote sensing, landscape flux measurements, and phenology to understand the impacts of climate change on Australian landscapes. This project aims to combine satellite data with field tower measurements to more accurately map the water and carbon status of Australian landscapes. This will provide valuable information on land surface changes and improve model predictions of water balance, productivity, and health in response to climate change and land use impacts.
Effect of climate boundary changes on the Southern Westerly Winds. This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they ....Effect of climate boundary changes on the Southern Westerly Winds. This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they do so limits attempts at accurate predictive climate modelling. This project will test conceptual models of SWW dynamics and provide essential boundary conditions for predictive climate models. The project intends to simultaneously build and support a research capacity and global network, and advance Australia’s knowledge and contribution in the area of global climate dynamics.Read moreRead less
Snake fangs: insights into evolution, palaeoclimate and biodesign . This project aims to generate unprecedented insights into the fangs of venomous snakes, focusing on elapids (taipans, tiger snakes etc). We will examine fang shape diversity, correlation with behavior and ecology, evolutionary history, and biomechanical properties. Data will be collected using cutting-edge micro-CT technology and analysed using 3D geometric morphometrics, computer simulations, and advanced phylogenetic techniqu ....Snake fangs: insights into evolution, palaeoclimate and biodesign . This project aims to generate unprecedented insights into the fangs of venomous snakes, focusing on elapids (taipans, tiger snakes etc). We will examine fang shape diversity, correlation with behavior and ecology, evolutionary history, and biomechanical properties. Data will be collected using cutting-edge micro-CT technology and analysed using 3D geometric morphometrics, computer simulations, and advanced phylogenetic techniques. This should greatly improve understanding of the evolution of venom fangs in all snakes. Other benefits include a large 3D reference database allowing identification of fossil fangs, with applications for studies of past climates, and a characterisation of fang biomechanics, relevant to biodesign and biomimicry.Read moreRead less
The legacy of rainfall patterns in dryland ecosystems. This project aims to use an experimental approach to determine how rainfall regime structures dryland communities and ecosystem properties and potential responses to altered rainfall regime. Ecosystem functioning in drylands is governed by complex interactions between microbes, invertebrates and plants. Biological activity however is constrained by the availability of water and altered rainfall regimes that could moderate how organisms inter ....The legacy of rainfall patterns in dryland ecosystems. This project aims to use an experimental approach to determine how rainfall regime structures dryland communities and ecosystem properties and potential responses to altered rainfall regime. Ecosystem functioning in drylands is governed by complex interactions between microbes, invertebrates and plants. Biological activity however is constrained by the availability of water and altered rainfall regimes that could moderate how organisms interact, potentially causing trophic cascades and even ecosystem state changes. By linking observed responses with soil microbial functional attributes using newly developed molecular techniques the project seeks to provide a mechanistic insight into ecosystem responses to climate variability and extreme climatic events.Read moreRead less
Climate model validation and generation of probabilistic climate projections using data from Phase 5 of the Climate Model Intercomparison Project. New climate model results will be compared with observations to test model skill. Probabilistic projections of regional-scale climate change will be developed and used to investigate a number of ecosystem impact case studies.
Geomorphological development of coral reefs, southern Great Barrier Reef: an integrated record of Holocene palaeoecology and palaeoclimate from cores. Very little is known about how the Great Barrier Reef (GBR) has responded or may respond to predicted environmental change and/or degradation. The project will reconstruct the recent biological and physical history of reefs in the southern GBR in order to better understand how they may react to future environmental changes.

Summary
A high precision, automated system for studying greenhouse gas cycling in coastal environments. This facility will perform automated, long-term greenhouse gas measurements in coastal waters. The expected outcome of research at this facility is a better understanding of how the coastal ocean acts as a source or sink of carbon dioxide, nitrous oxide, methane, and volatile organic carbon.

A gamma spectrometry facility for cutting edge environmental geochemistry investigations: This project will provide a cutting edge gamma spectrometry facility. The facility will perform high precision radionuclide measurements to resolve complex environmental processes such as sediment accumulation, soil erosion, submarine groundwater discharge, atmospheric deposition, marine carbon scavenging, and water mass circulation. This project is significant because the data obtained will fill fundamental gaps in the understanding of carbon, nitrogen, and trace metal cycling in soils, groundwater, rivers, estuaries, and the ocean. The outcome of this project is a better understanding of regional and global biogeochemical cycles. Read moreRead less
