Tackling marine conservation issues at national and global scales. This project aims to collect and apply standardised underwater data on fishes, invertebrates and plants in an unprecedented global analysis of decadal change in rocky and coral reef ecosystems.

This project aims to collect and apply standardised underwater data on fishes, invertebrates and plants in an unprecedented global analysis of decadal change in rocky and coral reef ecosystems. Outcomes will include validation of global models of ocean warming and understanding of poorly known ecological impacts of recreational fisheries. A suite of data-informed recommendations developed through engagement across management, science and public sectors will benefit Australians by enabling improved sustainability of resource use. International benefits will propagate through increased data access, improvements in predictive models and the evidence base required for large-scale biodiversity-related policy reform.Read moreRead less
Resolving the warming East Australian Current's impact on a marine food web. Resolving the warming East Australian Current's impact on a marine food web. This project aims to understand the effects of climate change on marine food webs, from plankton production to predation by iconic marine fauna, by integrating data on oceanographic conditions and fish distribution with the foraging patterns and breeding success of seabirds.

Resolving the warming East Australian Current's impact on a marine food web. This project aims to understand the effects of climate change on marine food webs, from plankton production to predation by iconic marine fauna, by integrating data on oceanographic conditions and fish distribution with the foraging patterns and breeding success of seabirds. Warming waters due to strengthening western boundary currents have unknown consequences for coastal marine food webs. Innovative prey capture signatures from accelerometers, and advanced movement models from satellite locations will show how predators locate and prey upon fish schools. Anticipated outcomes are insight into how changing resource availability in the oceans affects ecosystem resilience; improved viability for coastal industries; and ecosystem-based conservation management strategies.Read moreRead less

Summary
A laser optical plankton counter for laboratory and in-situ size distributions of zooplankton, to assess the basis and outcomes of changing ecosystems. The researchers will integrate studies of zooplankton biodiversity from the tropics to the Southern Ocean with an optical plankton counter to quickly measure zooplankton size and approximate shape. This new technology, together with a resurgence in collaborative marine science through the Integrated Marine Observing System and the Sydney Institut ....A laser optical plankton counter for laboratory and in-situ size distributions of zooplankton, to assess the basis and outcomes of changing ecosystems. The researchers will integrate studies of zooplankton biodiversity from the tropics to the Southern Ocean with an optical plankton counter to quickly measure zooplankton size and approximate shape. This new technology, together with a resurgence in collaborative marine science through the Integrated Marine Observing System and the Sydney Institute of Marine Science, will enable Australian researchers to understand changes in the plankton in freshwater or in estuaries, as well as in the East Australian Current. This current has already strengthened and is predicted to be the area of greatest warming in the Southern Hemisphere. The response of plankton communities to these changes will have profound effects on Australian fisheries and livelihoods.Read moreRead less
Effect of Global Change on the Primary Production of Antarctic coastal Ecosystems. As the climate warms, sea ice in Antarctic coastal areas will reduce. Most primary production currently occurs within the sea ice. We propose that a reduction in ice extent will lead to a reduction in ice production but greater benthic production; phytoplankton production will stay relatively constant. These changes will significantly effect the size of pelagic (ie fish) and benthic (starfish, sea urchins etc) st ....Effect of Global Change on the Primary Production of Antarctic coastal Ecosystems. As the climate warms, sea ice in Antarctic coastal areas will reduce. Most primary production currently occurs within the sea ice. We propose that a reduction in ice extent will lead to a reduction in ice production but greater benthic production; phytoplankton production will stay relatively constant. These changes will significantly effect the size of pelagic (ie fish) and benthic (starfish, sea urchins etc) stocks, which in turn will impact on the size of seal and penguin populations. Our project will allow predictions of these changes that have been induced by a reduction in sa ice extentRead moreRead less
Dynamic resilience and stability properties of marine systems: the importance of environment-engineer feedbacks in kelp forests. Kelp forests form complex habitats that support diverse, productive and economically important food-webs. This project will determine whether healthy kelp forests engineer their environment to make conditions more suitable for their continued recruitment and survivorship, thus increasing their stability and resilience in response to anthropogenic threats.
The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.

The Integrated Marine Observing System (IMOS) science plans include sampling campaigns reliant on Autonomous Underwater Vehicle (AUV) Facility data and designed to address the issues of marine biodiversity quantification and assurance. The proposed research will directly enhance the effectiveness of these programs by speeding labour-intensive analyses, aggregating the results, and searching for ecological patterns on a national scale that would be difficult to identify using traditional approaches tuned to process-scale studies. Australian society stands to benefit by virtue of improved large-scale models of ecosystem function and reduced cost for conducting marine ecosystem investigations.Read moreRead less
Improving prediction of rocky reef ecosystem responses to human impacts. This project aims to improve our understanding of inshore ecosystems to facilitate better management of our living marine heritage. The project first aims to extend field datasets on the density and distribution of thousands of marine fishes, invertebrates and macro-algae.

This project aims to improve our understanding of inshore ecosystems to facilitate better management of our living marine heritage. The project first aims to extend field datasets on the density and distribution of thousands of marine fishes, invertebrates and macro-algae. These will then be combined using recent advances in quantitative ecological modelling to describe transfer of biomass between species at hundreds of sites, with a primary focus on southern Australia. It is anticipated that this will provide site-level indices of major food web processes that, when combined with ‘before, after, control, impact’ data, will improve prediction of ecological consequences of fishing, climate change, pest outbreaks and pollution.Read moreRead less

This project expects to create new knowledge for enhancing restoration success for seagrasses by integrating macro and micro-ecology, environmental genomics, plant ecology and ecosystem function (e.g. nutrient and biogeochemistry cycling). Expected outcomes are new knowledge to enhance seagrass restoration utilising sediment microbes that can be integrated into management and policy. This project should provide significant benefits, such as the development of key strategic alliances to enhance management of seagrasses, and the ecosystem services, and economic and social benefits they provide.Read moreRead less
