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
Assessing the risk of ocean acidification for the Great Barrier Reef. The increase in greenhouse gases such as CO2 represents a challenge for coral reefs such as Australia's Great Barrier Reef (GBR).

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
Bluebottle dynamics: towards a prediction tool for Surf Life Saving Aust.

Many Australians have had a painful bluebottle sting, yet little is known about bluebottles and what brings them to the coast. This project will shed new light on bluebottle dynamics, pathways, and distribution of the beachings. We will use an innovative combination of lab work, ocean surveys, statistical and hydrodynamic modelling to fill knowledge gaps and ultimately provide the framework for prediction.
In partnership with Surf Life Saving Australia (SLSA), we will develop the first bluebottle risk prediction tool for our popular beaches.
Forewarned is forearmed. Forecasts will help mitigate bluebottle stings, lessen their public health burden, while having broad benefits for coastal communities.

New technology of HF ocean radar can map wave fields over coastal waters and thus fill a gap between the open ocean satellite measurements and the point measurements from wave buoys. In this project we will improve the analysis of the radar echoes to produce sea wave spectra, and evaluate focussing of waves by complex currents on the continental shelf to help improve wave forecasting in coastal waters. The HF radar will be used to experimentally test current theories of wind wave spreading.Read moreRead less

At the same time, the project will build sovereign capability in emerging remote sensing technology with a legacy beyond the life of the SWOT mission.Read moreRead less
Effects of river plumes on nearshore ecosystems: organic matter flows and food web consequences. River plumes may subsidize nearshore food webs by exporting land-derived material and by stimulating marine phytoplankton production via nutrient delivery. Whereas previous documentation of the biological responses to plumes has been mostly limited to large rivers and to primary production, this project targets small systems that discharge directly onto open coasts, and focuses on the fate of plume ....Effects of river plumes on nearshore ecosystems: organic matter flows and food web consequences. River plumes may subsidize nearshore food webs by exporting land-derived material and by stimulating marine phytoplankton production via nutrient delivery. Whereas previous documentation of the biological responses to plumes has been mostly limited to large rivers and to primary production, this project targets small systems that discharge directly onto open coasts, and focuses on the fate of plume material. Work on carbon pathways will centre on pelagic and benthic food chains associated with plumes, and will also test whether nearshore waters and sandy beaches are coupled via onshore advection of plume material.Read moreRead less
