Australian climate extremes and predictability in a changing CO2 world: the unique role of the Southern Hemisphere extratropical ocean-atmosphere. Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next fifty years.

Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next fifty years. Research into climate variability, extremes, and predictability is thus highly significant for Australia, and will underpin efforts to protect our biodiversity and ensure the nation's environmental sustainability. We propose to launch a major new initiative in extratropical climate analysis. This work will have significant benefits for the many sectors of society reliant on interseasonal-interannual climate prediction. Prominent examples include agriculture, energy, freshwater supply, bushfire control, air quality, health, and tourism.Read moreRead less

What controls the shift from a hot house climate to a cold house climate: the Eocene/ Oligocene climate transition and greenhouse warming. This study contributes to putting Australia on the map as a centre of excellence in the study of past climates as well as in global warming research. It aims at a greater understanding of the dynamics of past warm climate states. This could ultimately lead to a better knowledge of the formation of the ancient deposits that we mine in Australia today.

This study contributes to putting Australia on the map as a centre of excellence in the study of past climates as well as in global warming research. It aims at a greater understanding of the dynamics of past warm climate states. This could ultimately lead to a better knowledge of the formation of the ancient deposits that we mine in Australia today. Furthermore, the study of these past warm climates tells us something about current global warming as both involve increased levels of carbon in the atmosphere. The impact of climate change on Australia is likely to be large. Our study of past warm climates helps to gain an understanding of the mechanisms behind climate change and help quantify the risks of climate change posed to Australia.Read moreRead less

Impacts of climate change on coastal floodplain wetland biogeochemistry and surface water quality. The most vulnerable Australian landscapes to global warming driven sea-level rise are our low-lying coastal floodplains. Seawater inundation dramatically affects soil chemistry and water quality. Over 74,000 km2 of the low-lying coastal floodplains of Australia contain acid sulfate soils. For these soils, seawater inundation has the potential to greatly enhance the release of acidity, with a high c ....Impacts of climate change on coastal floodplain wetland biogeochemistry and surface water quality. The most vulnerable Australian landscapes to global warming driven sea-level rise are our low-lying coastal floodplains. Seawater inundation dramatically affects soil chemistry and water quality. Over 74,000 km2 of the low-lying coastal floodplains of Australia contain acid sulfate soils. For these soils, seawater inundation has the potential to greatly enhance the release of acidity, with a high capacity to severely degrade wetlands, estuaries and farmland. This project will directly contribute to our national capacity to assess and manage impacts from climate change, providing greater protection of our coastal floodplains resources.Read moreRead less
Development and calcification in benthic marine invertebrates (Mollusca and Echinodermata) in an acidified and warm ocean. As an island continent Australia generates considerable wealth from its oceans with marine invertebrate resources playing a key role. These resources are at risk due to the impact of climate change, ocean acidification and warming, on availability of carbonate minerals for shell production.

As an island continent Australia generates considerable wealth from its oceans with marine invertebrate resources playing a key role. These resources are at risk due to the impact of climate change, ocean acidification and warming, on availability of carbonate minerals for shell production. Of major concern is potential recruitment failure if planktonic larvae cannot produce their skeleton and if benthic stages cannot grow due to impaired skeleton formation. This project addresses uncertainties in knowledge of the response of ecologically and commercially important marine biota to climate change, knowledge crucial to inform risk assessment of future changes to our marine resources.Read moreRead less

Summary
World-leading elemental and isotopic microanalysis and chemical speciation facilities for an environmentally sustainable Australia. We propose to establish a world-leading centre for the study of the elemental and isotopic composition of key environmental, archaeological and mineral samples. This will be based upon ultra-short wavelength laser ablation and speciation methods, combined with new advanced ICP-MS technologies developed in Australia.

We propose to establish a world-leading centre for the study of the elemental and isotopic composition of key environmental, archaeological and mineral samples. This will be based upon ultra-short wavelength laser ablation and speciation methods, combined with new advanced ICP-MS technologies developed in Australia. This will give the centre unrivalled capabilities and allow new areas of research to be undertaken in global climate change, the impact of increased salinity and pollution on the sustainability of Australia's inland waterways and coastal environments, and the history of the first humans who inhabited Australia. This will provide a baseline and new quantitative measures to better plan for an environmentally sustainable Australia.Read moreRead less
Large-scale climatic control of coastal erosion and shoreline changes based on long-term survey dataset and video monitoring technology. The Australian coastline is one of this country's greatest natural and economic resources. The asset value of existing coastal infrastructure is immeasurable.

The Australian coastline is one of this country's greatest natural and economic resources. The asset value of existing coastal infrastructure is immeasurable. From past experiences in Australia and overseas, coastal erosion is a major and growing threat to the long-term sustainability of coastal development and the coastal environment. This research will integrate a unique multi-decade dataset of beach surveys and innovative coastal imaging technology, examining the relationship of shoreline movements to changing climatic signals, to enable better prediction of future shoreline changes. This new understanding will inform and strengthen the skills and capacity of Australia's coastal managers.Read moreRead less
Defining the relationship between microscale wave breaking and enhanced air-water interfacial exchange rates of low solubility gases. Accurate parameterisations of absorption rates of low-solubility gases (e.g. oxygen, carbon dioxide) across open air-water interfaces are important to industry and the environmental sciences, e.g. for estimating carbon dioxide transfer rates in industry and the global environment as well as rates of the re-aeration of nutrient-enriched water. Recent studies show t ....Defining the relationship between microscale wave breaking and enhanced air-water interfacial exchange rates of low solubility gases. Accurate parameterisations of absorption rates of low-solubility gases (e.g. oxygen, carbon dioxide) across open air-water interfaces are important to industry and the environmental sciences, e.g. for estimating carbon dioxide transfer rates in industry and the global environment as well as rates of the re-aeration of nutrient-enriched water. Recent studies show that at open air-water interfaces under moderate wind forcing, absorption rates are primarily determined by microscale wave breaking. This project will determine the dependence of gas flux rates on the scale, strength and intermittency of microscale wave breaking and, by incorporating this key process, produce substantially improved predictive schemes.Read moreRead less
