Modelling of sand wave migration and its interaction with pipelines. The movement of sand due to sand waves can interfere with marine structures such as pipelines and cables on the seabed. It may also cause free spans of pipelines, with potentially serious consequences. Most previous research has considered sand wave propagation and the stability of pipelines as separate problems. In this project, we propose a coupled analysis of sand wave migration and its interaction with pipelines through mat ....Modelling of sand wave migration and its interaction with pipelines. The movement of sand due to sand waves can interfere with marine structures such as pipelines and cables on the seabed. It may also cause free spans of pipelines, with potentially serious consequences. Most previous research has considered sand wave propagation and the stability of pipelines as separate problems. In this project, we propose a coupled analysis of sand wave migration and its interaction with pipelines through mathematical and numerical modelling. The theoretical work will be supported by laboratory experiments. The resulting research will provide a better understanding of sand wave migration, beach profiles and the stability of pipelines.Read moreRead less

This project aims to improve the success of hybrid living shorelines that combine the restoration of mangroves and oysters with engineered structures to enhance restoration outcomes and coastal hazard resilience. It expects to generate new knowledge on the effectiveness of innovative coastal-manager-led solutions that have not yet been robustly evaluated. Expected outcomes of this project include delivery of the technical guidelines needed to practically design and implement nature-based coastal protection at scale. This should provide significant socio-economic and environmental benefits through improving Australia’s capacity to adapt to increased erosion and flood risk caused by climate change and coastal urbanisation.Read moreRead less
Understanding marine migratory connectivity for more sustainable oceans. Ocean basin-scale migrations of iconic sea turtles, marine mammals, seabirds, and fish expose them to multiple stressors and governance regimes, leading to gaps in management and population declines.

conservation of these species. Expected outcomes include comprehensive and integrated models of mig ....Understanding marine migratory connectivity for more sustainable oceans. Ocean basin-scale migrations of iconic sea turtles, marine mammals, seabirds, and fish expose them to multiple stressors and governance regimes, leading to gaps in management and population declines. The project aims to deliver the methods and evidence base of cross-taxa migratory connectivity that is essential to support the
conservation of these species. Expected outcomes include comprehensive and integrated models of migratory connectivity, conservation theory development, and new methods that allow incorporation of migratory connectivity in conservation planning. Benefits include: a cross-taxa baseline that will enable Australia to measure environmental change in marine migratory connectivity for the first time.Read moreRead less
An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host ....An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host and symbiont response to changing water temperature along a latitudinal gradient. The intended outcome of the project is to provide knowledge to support predictions of likely species migrations from tropical to subtropical waters, enabling managers to anticipate the future response of coral communities to seawater warming.Read moreRead less
Microscale insights into ocean-scale processes: microbial behaviour as a driver of ocean biogeochemistry. Microscopic plankton regulate the ocean's chemical cycles, which ultimately support life on earth. However, the ecological interactions driving these processes are poorly understood. This project will use novel approaches to decipher the behaviours of marine microbes, providing a more complete perception of how ocean ecosystems operate and influence climate.

Fundamental aspects of vertical and horizontal consolidation in a multi-layered soil system. Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation. After valida ....Fundamental aspects of vertical and horizontal consolidation in a multi-layered soil system. Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation. After validation using experimental data and numerical simulations, the proposed analytical model can be used to mimic soil behaviour more closely than traditional models, thereby leading to more realistic settlement predictions.Read moreRead less
Orientation in the pelagic environment: how do larval marine fish find their way home? This study will determine what senses tiny fish larvae use to orientate in the ocean and to influence where currents disperse them. Because larval dispersal determines the spatial extent of fish populations, this knowledge is important for management of marine fisheries and the design and operation of marine parks.
