Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critica ....Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critical threshold limits of CO2 emissions for sustainable calcification in both shallow tropical and deep-water marine ecosystems of the Southern Oceans.Read moreRead less
Abrupt Southern Hemisphere Climate Change: The Role Of The Southern Ocean Thermohaline Circulation. 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 ten-fifty years. Research into climate change and climate variability is thus highly significant for Australia, and will underpin efforts to protect our biodiversity and ensure the nation's environmental sustai ....Abrupt Southern Hemisphere Climate Change: The Role Of The Southern Ocean Thermohaline Circulation. 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 ten-fifty years. Research into climate change and climate variability 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 study of the stability of the Southern Ocean's thermohaline circulation and its role in global climate. This work could have significant long-term benefits for those sectors of society sensitive to shifts in climate; including agriculture, energy, freshwater supply, health, and tourism.Read moreRead less
New tools for managing ecosystem responses to climate change on the southern Great Barrier Reef. The Great Barrier Reef (GBR) underpins over $4 billions of economic activity each year. Recent evidence suggests that reefs like the GBR are vulnerable to climate change, which manifests itself at both local and global scales. Providing the tools for tracking and understanding these changes is vitally important to effective reef management strategies. This project will provide a major advance in o ....New tools for managing ecosystem responses to climate change on the southern Great Barrier Reef. The Great Barrier Reef (GBR) underpins over $4 billions of economic activity each year. Recent evidence suggests that reefs like the GBR are vulnerable to climate change, which manifests itself at both local and global scales. Providing the tools for tracking and understanding these changes is vitally important to effective reef management strategies. This project will provide a major advance in our understanding and the tools available to manage the impacts of climate change. In doing so, it will also produce the first comprehensive and multidisciplinary look at how environmental variability impacts coral reef organisms from corals to seabird populations.Read moreRead less

Ocean-reef interactions as drivers of continental shelf productivity in a changing climate. Poor coastal management results in the irreparable destruction of reef systems' function and biodiversity, nationally and globally. To manage marine resources effectively we must implement sustainable practices, including forward planning in the context of climate change. A critical limitation in determining appropriate actions is a poor understanding of mechanisms driving productivity. Our project will p ....Ocean-reef interactions as drivers of continental shelf productivity in a changing climate. Poor coastal management results in the irreparable destruction of reef systems' function and biodiversity, nationally and globally. To manage marine resources effectively we must implement sustainable practices, including forward planning in the context of climate change. A critical limitation in determining appropriate actions is a poor understanding of mechanisms driving productivity. Our project will provide key information on the oceanographic mechanisms supporting Australia's coastal systems, linking nutrient supply, physical drivers and climate. By linking all these factors we will both assist in determining appropriate ecosystem management, and provide a knowledge base to support adaptation to future changes in Australia's climate.Read moreRead less
Sensitivity and Change in the Global Ocean Overturning. The dynamics of the global, deep overturning circulation in the oceans and the way this adjusts to increasing greenhouse forcing will be examined in order to improve our conceptual knowledge of the oceans and the accuracy of climate models. By understanding how the ocean responds to changing surface heat and freshwater fluxes, and particularly the global role of rapid changes in high-latitude seas, we aim to help refine estimates of climate ....Sensitivity and Change in the Global Ocean Overturning. The dynamics of the global, deep overturning circulation in the oceans and the way this adjusts to increasing greenhouse forcing will be examined in order to improve our conceptual knowledge of the oceans and the accuracy of climate models. By understanding how the ocean responds to changing surface heat and freshwater fluxes, and particularly the global role of rapid changes in high-latitude seas, we aim to help refine estimates of climate response times and the warming expected for a given increase in atmospheric greenhouse gases. These two important characteristics of the climate system underlie climate change policy decisions.Read moreRead less

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

The increase in greenhouse gases such as CO2 represents a challenge for coral reefs such as Australia's Great Barrier Reef (GBR). While the impact of greenhouse warming on coral reefs has been partially explored, the potentially serious implications of a decrease in ocean pH due have not been properly assessed. Detecting and understanding changes to carbonate concentrations and reef calcification are of great importance if managers are to respond strategically to potential ecological changes. This project directly addresses National Research Priority 1 of achieving 'An Environmentally Sustainable Australia' by addressing the priority goal of 'Responding to climate change and variability'.Read moreRead less

New velocity observations will tell us how the vertical mixing that contributes to the meridional overturning circulation, and ACC strength, change with the seasons and from year to year. The observations will also give us a better understanding of the oceanic and atmospheric processes that drive these changes. This new information will allow climate models to be better constrained so they can more accurately predict changes to Australian and global climate.Read moreRead less
