The Great Barrier Reef is a World Heritage Area, home to over 1 million species and provides Australia with $6 billion in annual revenue. The capacity to monitor Australia’s natural resources and changes in condition are integral components of a sustainably and adaptively managed resource. By providing key synoptic tools to comprehensively monitor water quality and ecosystem status, the project will contribute directly to an Environmentally Sustainable Australia and improve national capacity for responding to climate change and variability in coral reef environments. It will enable Australian remote sensing scientists to contribute knowledge and tools to the international community for application to coral reef and coastal waters globally. Read moreRead less
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

The objectives of this project are to undertake a major, long term study of the impact of global structural change on greenhouse gas emissions and on climate change, and to develop a detailed knowledge base concerning trade in embodied emissions. It is hoped that the knowledge generated will both inform global responses to this vital problem and contribute to the continuing development of effective responses within Australia. The output - a book and many papers - will be directed in part to contribute to the IPCC's Fourth Assessment Report.Read moreRead less
Non-CO2 greenhouse gas emissions in afforested ecosystems in southeastern Australia - fluxes, processes and regional budget. There are no data available about the extent of emissions of the non-CO2 greenhouse gases nitrous oxide and methane from soils of forest ecosystems in Australia and the current methodolgy to quantify these emissions contains high uncertainties. Using the latest technology available we propose to i) measure emission rates of afforested ecosystems for non-CO2 greenhouse gase ....Non-CO2 greenhouse gas emissions in afforested ecosystems in southeastern Australia - fluxes, processes and regional budget. There are no data available about the extent of emissions of the non-CO2 greenhouse gases nitrous oxide and methane from soils of forest ecosystems in Australia and the current methodolgy to quantify these emissions contains high uncertainties. Using the latest technology available we propose to i) measure emission rates of afforested ecosystems for non-CO2 greenhouse gases in relation to previous land-use in southeastern Australia, ii) identify the processes controlling the emissions, iii) use the obtained data to calibrate a biogeochemical model, and iv) use the model to estimate regional inventories for non-CO2 greenhouse gas emissions in southeastern Australia.Read moreRead less
The Impact of Changing Climatic Conditions inferred from the Isotope Abundances of Trace Metals in Global Ice Sheets and Glaciers. In this project Greenland and Antarctic ice-cores more than 3 km long will be used to investigate climatic variation extending back more that 4 complete glacial cycles. Some of these ice-cores include sections of refrozen water formed from sub-glacial Antarctic lake water.

In this project Greenland and Antarctic ice-cores more than 3 km long will be used to investigate climatic variation extending back more that 4 complete glacial cycles. Some of these ice-cores include sections of refrozen water formed from sub-glacial Antarctic lake water. This project will use naturally occurring lead and strontium isotopic tracers to fingerprint impurities in the ice, because they have the potential to simultaneously signal the timing and location of past episodes of climate change. This will lead to an improvement in our understanding of the processes that cause these changes.Read moreRead less

This project will lead to significant advances in our understanding of the Ningaloo Current system that dominates the regional circulation surrounding Ningaloo Marine Park, part of the National Representative System of Marine Protected Areas. The numerical model and field measurements will, for the first time, elucidate which physical factors drive the Ningaloo Current and the resulting spatial and temporal variability of upwelling. This will ultimately provide insight into how various ecological processes are linked to hydrodynamics (e.g., nutrient delivery, bleaching) and help assess how susceptible the reef ecosystem may be to changes to physical forcing resulting from climate change.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
