Plutonium - A new tracer of sediment transport into the Great Barrier Reef Lagoon. This work will quantify one of the most controversial threats to the Great Barrier Reef Marine Park, namely the amount of sediment reaching the reef as a consequence of human activities. It will have economic implications for this major Australian tourist attraction, as well as the commercial fishing and agricultural and horticultural industries in the region. The direct economic value associated with these indust ....Plutonium - A new tracer of sediment transport into the Great Barrier Reef Lagoon. This work will quantify one of the most controversial threats to the Great Barrier Reef Marine Park, namely the amount of sediment reaching the reef as a consequence of human activities. It will have economic implications for this major Australian tourist attraction, as well as the commercial fishing and agricultural and horticultural industries in the region. The direct economic value associated with these industries exceeds $1 billion per annum, and around 1 million people visit the inshore areas every year. Management of the park will benefit through improved understanding of the transport of sediment from the rivers to the lagoon and inner reef areas, and the fraction of the sediment attributable to anthropogenic practices.

Summary
Acoustic tracking key marine species in Tasmania using new technology. We will use new passive listening receivers and uniquely indentifiable acoustic tags to track key marine species (squid, octopus, fish and crustaceans) in Tasmania. This technology allows us to remotely track species with a level of detail previously not available. By using a large number of receivers we will build listening 'curtains'. A series of curtains will then form a multi-species listening grid. This equipment wi ....Acoustic tracking key marine species in Tasmania using new technology. We will use new passive listening receivers and uniquely indentifiable acoustic tags to track key marine species (squid, octopus, fish and crustaceans) in Tasmania. This technology allows us to remotely track species with a level of detail previously not available. By using a large number of receivers we will build listening 'curtains'. A series of curtains will then form a multi-species listening grid. This equipment will allow us to reconstruct movement between habitats, and migration routes to better understand and manage this marine ecosystem. An important feature will involve monitoring organism movements into and out of marine protected areas.Read moreRead less
THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES. The objective of this proposal is to quantify the environmental impacts of enhanced terrestrial fluxes and climate change on the coral reefs in the Great Barrier Reef. This will be achieved by using an integrated approach based on coral proxy records of river plumes and sea surface temperatures that are preserved in carbonate skeletons of the long-lived (200-400 year old) Porites coral. ....THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES. The objective of this proposal is to quantify the environmental impacts of enhanced terrestrial fluxes and climate change on the coral reefs in the Great Barrier Reef. This will be achieved by using an integrated approach based on coral proxy records of river plumes and sea surface temperatures that are preserved in carbonate skeletons of the long-lived (200-400 year old) Porites coral. This will be integrated with monitoring and process studies of river flood plumes and coral reefs and provide a scientific basis to ensure the long-term sustainability of the GBR.Read moreRead less
Bioeconomic Modelling of Marine Reserves. Australian waters contain a huge range of biodiversity, but are under threat from human activities. To face this challenge and resolve the problems of depleted fisheries and habitat destruction, innovative approaches are required to integrate marine biology with fisheries economics.

Australian waters contain a huge range of biodiversity, but are under threat from human activities. To face this challenge and resolve the problems of depleted fisheries and habitat destruction, innovative approaches are required to integrate marine biology with fisheries economics. The research meets this immediate need by developing bioeconomic models of marine reserves to determine reserve location and size, and analyse interactions between reserves and harvested areas under environmental uncertainty. The models will be developed using the latest developments in economics, biology and numerical methods and will be used to conserve Australia's marine biodiversity and improve fisheries management.Read moreRead less
