Research outcomes from this new facility will empower government bodies, resource industries, and indigenous stakeholders with key baseline information to ensure the sustainable and sensitive development of west Australia's unique coastal and offshore regions, across heavily populated and pristine environments. This includes projecting future impacts on local industries (eg. energy, fisheries, tourism), rising shorelines with critical implications for existing and developing communities, and enhancing the resilience of habitats at risk. These are crucial to mitigate the impacts from environmental change that could severely affect our regional and national economies, as well as the style and quality of life of current and future generations.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
Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entir ....Longshore Sediment Supply to the Deep Ocean. The current model to supply sand to deep water off continental margins is that provided by rivers operating at low sea level. We propose an alternative model in which sand is provided by longshore transport to deep water at high sea level north of Fraser Island, SE Queensland. Here we will test the validity of our new model by site studies of sea bottom morphology, composition and dynamics. If the model proves true, we will have: 1) generated an entirely new exploration model for deepwater hydrocarbons, 2) provided new expertise and seabed maps for generating a superior marine naval defence capability.Read moreRead less
Winter temperature and salinity profile measurements in the Southern Ocean using elephant seals as ocean sampling platforms. As a result of the paucity of winter data in the Southern Ocean, sophisticated ocean models such as the GFDL MOM are hampered in their ability to properly represent the complex processes in the Antarctic sea ice zone. Elephant seals forage in the Southern Ocean throughout winter, and traverse the water column between 0 and 800 metres many times each day, providing an oppo ....Winter temperature and salinity profile measurements in the Southern Ocean using elephant seals as ocean sampling platforms. As a result of the paucity of winter data in the Southern Ocean, sophisticated ocean models such as the GFDL MOM are hampered in their ability to properly represent the complex processes in the Antarctic sea ice zone. Elephant seals forage in the Southern Ocean throughout winter, and traverse the water column between 0 and 800 metres many times each day, providing an opportunity to collect profiles of temperature and salinity. The resulting data will contribute to oceanographic studies of water mass formation and frontal variability, including comparisons with historical data and assimilation into a complex ocean model.Read moreRead less
Characterization of bioadhesives from marine diatom slimes and their interactions with different substrata; developing environmentally friendly, foul-release coatings. This project represents a collaborative effort between Melbourne University, the Department of Defense and Akzo Nobel to develop new, environmentally friendly strategies to modify and/or prevent marine slime adhesion in anti-foul coatings or paint. Fouling by diatom slimes occurs at great expense to industry and the Australian N ....Characterization of bioadhesives from marine diatom slimes and their interactions with different substrata; developing environmentally friendly, foul-release coatings. This project represents a collaborative effort between Melbourne University, the Department of Defense and Akzo Nobel to develop new, environmentally friendly strategies to modify and/or prevent marine slime adhesion in anti-foul coatings or paint. Fouling by diatom slimes occurs at great expense to industry and the Australian Navy, adding up to 60% annually to the cost of propulsive fuel consumption in shipping. We will characterize the chemical and physical properties of the slime adhesives in order to understand how organisms control adhesion, and use these principles to develop new technology, anti-foul paints.Read moreRead less
A Dynamical Systems Approach to Mapping Southern Ocean Circulation Pathways. Climate change can be expected to have complex, long-term consequences for Australia's biodiversity, for our agricultural and marine production systems, and for regional communities. The Southern Ocean is a critical driver of global climate, connecting the three major oceanic basins. Using sophisticated mathematics to analyse state-of-the-art global ocean models, this project will create a detailed picture of hitherto i ....A Dynamical Systems Approach to Mapping Southern Ocean Circulation Pathways. Climate change can be expected to have complex, long-term consequences for Australia's biodiversity, for our agricultural and marine production systems, and for regional communities. The Southern Ocean is a critical driver of global climate, connecting the three major oceanic basins. Using sophisticated mathematics to analyse state-of-the-art global ocean models, this project will create a detailed picture of hitherto invisible Southern Ocean circulation 'pathways'. The newly discovered pathways will greatly enhance our understanding of the Southern Ocean circulation, lead to improved coupled climate models, and increase our ability to predict future climate change and threats to marine populations.

Winter Foraging Locations Of Southern Ocean Predators In Relation To Stochastic Variation In Sea-Ice Extent. Antarctic marine communities are likely to be amongst the first anywhere to show changes due to climate change. A top national priority for Australia is to understand how Antarctic communities will be affected if climate change does occur. As predators reflect changes occurring lower in the food chain, these are an important group to study. This study will be the first to specifically lin ....Winter Foraging Locations Of Southern Ocean Predators In Relation To Stochastic Variation In Sea-Ice Extent. Antarctic marine communities are likely to be amongst the first anywhere to show changes due to climate change. A top national priority for Australia is to understand how Antarctic communities will be affected if climate change does occur. As predators reflect changes occurring lower in the food chain, these are an important group to study. This study will be the first to specifically link ice extent with the habitat use of predators, and quantify how this varies over time. Some work already indicates that there have been community level changes in some predators in the Antarctic due to changes in ice extent, so developing tools to predict the nature and magnitude of these changes are needed.

The structure and function of cyanobacterial carboxysome multi-protein complexes and their role in carbon sequestration in cyanobacteria. Cyanobacteria are important contributors to global photosynthesis and have evolved unique mechanisms for capturing CO2 from their aquatic environments.

Cyanobacteria are important contributors to global photosynthesis and have evolved unique mechanisms for capturing CO2 from their aquatic environments. Understanding these molecular mechanisms is important for both predicting how cyanobacteria affect carbon fixation at the global scale, and how their genetic specialisation may be used for improving photosynthesis in agricultural plants. This project aims to examine one particular aspect of this specialisation, the multi-protein carboxysome complex, where CO2 fixation occurs. Using recent whole-genome information we will take a proteogenomic approach to understanding the structure and function of the carboxysome and how it contributes to the photosynthesis of the cell.Read moreRead less
Benthic Processes and Oceanic Internal Waves. Direct observations will be made of the turbulent motion and sediment re-suspension near the sea bed of the ocean in regions strongly influenced by tides and internal waves. Combined with numerical models, the study will provide new insights into processes that are of fundamental importance to understanding the global dissipation of tidal energy and the role of internal waves in these processes.

Combined with numerical models, the study will provide new insights into processes that are of fundamental importance to understanding the global dissipation of tidal energy and the role of internal waves in these processes. With observations from the continental slope region of the Australian North West Shelf, results will also benefit the offshore engineering industry through knowledge of sediment scour and loadings on offshore structures.Read moreRead less
Hydrodynamics of Fringing Reef Systems. Ningaloo Marine Park is part of the National Representative System of Marine Protected Areas. Coral reefs are in a state of decline worldwide, yet Ningaloo Reef has remained in a relatively pristine state. However, its close proximity to land makes it particularly vulnerable to human activities, which are forecast to significantly grow in the near future. Results from this project will advance our ability to predict circulation on reefs and other similar c ....Hydrodynamics of Fringing Reef Systems. Ningaloo Marine Park is part of the National Representative System of Marine Protected Areas. Coral reefs are in a state of decline worldwide, yet Ningaloo Reef has remained in a relatively pristine state. However, its close proximity to land makes it particularly vulnerable to human activities, which are forecast to significantly grow in the near future. Results from this project will advance our ability to predict circulation on reefs and other similar coastal systems. This will provide insight into various ecological processes that are linked to hydrodynamics (e.g. recruitment), and will provide a foundation for conducting risk analysis of processes that threaten the integrity of nearshore environments (e.g. contaminant spills).Read moreRead less
