Is there a climatic tipping point for Antarctic Bottom Water formation? Antarctic Bottom Water plays an important role in global ocean circulation and climate and yet its formation is also highly sensitive to climate change. This project will analyse new seafloor, core and water samples from the understudied Cape Darnley, East Antarctica, collected on a voyage in early 2022. This new data will be used in combination with an improved high resolution regional ocean model, to understand modern and ....Is there a climatic tipping point for Antarctic Bottom Water formation? Antarctic Bottom Water plays an important role in global ocean circulation and climate and yet its formation is also highly sensitive to climate change. This project will analyse new seafloor, core and water samples from the understudied Cape Darnley, East Antarctica, collected on a voyage in early 2022. This new data will be used in combination with an improved high resolution regional ocean model, to understand modern and past Antarctic Bottom Water formation under different climate states (warmer and colder than present), to determine if there are climate tipping points for the shut down of Antarctic Bottom Water formation. The anticipated benefits include a better understanding of future climate change on this important water mass.Read moreRead less
Multiphase flow and transport in complex coastal wetland systems. Salt marshes play an essential role in maintaining Australia's coastal bio-diversity. They also function as barriers to fluxes of terrestrial pollutants to our coastal sea. Australia has a large number of salt marshes listed by the Ramsar Convention as coastal wetlands of international importance but many of them are subject to loss and degradation due to competing land uses. This project, examining in detail the flow and transpor ....Multiphase flow and transport in complex coastal wetland systems. Salt marshes play an essential role in maintaining Australia's coastal bio-diversity. They also function as barriers to fluxes of terrestrial pollutants to our coastal sea. Australia has a large number of salt marshes listed by the Ramsar Convention as coastal wetlands of international importance but many of them are subject to loss and degradation due to competing land uses. This project, examining in detail the flow and transport processes in marsh soils, will lead to (1) better understanding of the marsh's response to anthropogenic stress; and (2) improvement of strategies and methods for marsh wetland preservation and restoration.Read moreRead less
Measuring the flushing time of waters in the Great Barrier Reef. There are concerns both in the scientific community and in the general public about the possible implications of agricultural runoff to the Great Barrier Reef (GBR). Due to this, the Great Barrier Reef Marine Park Authority has developed a "Reef Water Quality Protection Plan" (RWQPP) which may have significant economic implications to the grazing, sugar, and other primary industries. In order to protect the GBR, whilst also minimiz ....Measuring the flushing time of waters in the Great Barrier Reef. There are concerns both in the scientific community and in the general public about the possible implications of agricultural runoff to the Great Barrier Reef (GBR). Due to this, the Great Barrier Reef Marine Park Authority has developed a "Reef Water Quality Protection Plan" (RWQPP) which may have significant economic implications to the grazing, sugar, and other primary industries. In order to protect the GBR, whilst also minimizing the impacts on agricultural industries, it is important to understand the processes that affect the buildup and broad-scale dispersion of contaminants in the GBR. This project will facilitate that understanding.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.

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.

The model will include the effects of tides, winds, surface gravity waves and density. The model results will be compared to field measurements collected by the Australian Institute of Marine Science. After the model has been developed and validated, it will be used to investigate processes such as water e ....Hydrodynamics of Fringing Reef Systems. This project aims to develop a numerical circulation model applicable to fringing reef systems, in particular, the Ningaloo reef, Western Australia. The model will include the effects of tides, winds, surface gravity waves and density. The model results will be compared to field measurements collected by the Australian Institute of Marine Science. After the model has been developed and validated, it will be used to investigate processes such as water exchange between lagoons and open sea, effects of contaminant spills and recruitment within the reef systems. An understanding of these processes is essential for the sustainable management of these systems.Read moreRead less

Connecting big data with high performance computing for climate science: The ARC Centre of Excellence for Climate System Science is a key user of the National Computational Infrastructure facility (NCI). This research requires massive data integrated with high performance computing in an operational facility. Fast disk capacity that is simultaneously connected to NCI long-term storage, cloud and high performance computing severely limits use of the NCI. To resolve this limitation, 1.7 petabytes of storage will be installed to transform the efficiency of the facility. This will enable more ambitious science to be undertaken. This investment will be used to launch a transformation from petascale to exascale problems and communicate the lessons learned to other research communities in Australia.Read moreRead less

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
An integrated examination of the drivers of movements of large filter feeding organisms of high ecotourism value: a case study. This aim is to define key drivers behind movements of large filter-feeding organisms, using the manta ray as a model system. As dive eco-tourism often depends on the presence of such charismatic filter-feeding animals, an understanding of why animals occupy particular sites at particular times is important, especially in the face of climate change.
