Summary
Understanding the termination of El Nino-Southern Oscillation events. Australia's climate is extreme, with significant drought and flooding events driven by cycles of the El Nino-Southern Oscillation (ENSO). This study will improve our understanding of the termination of ENSO events and lead to better inter-seasonal climate forecasting, aiding the sectors reliant on accurate climate prediction.

Summary
Internal wave breaking and mixing in the ocean. This project aims to quantify turbulent mixing in the ocean using ultra-high-resolution numerical modelling. Turbulent mixing is caused by internal waves which transport energy from the ocean boundaries into the interior, where they drive mixing of cold, deep water with warmer water above. This mixing is crucial to the ocean circulation which controls the storage of heat and carbon in the ocean, but is inadequately represented in current climate mo ....Internal wave breaking and mixing in the ocean. This project aims to quantify turbulent mixing in the ocean using ultra-high-resolution numerical modelling. Turbulent mixing is caused by internal waves which transport energy from the ocean boundaries into the interior, where they drive mixing of cold, deep water with warmer water above. This mixing is crucial to the ocean circulation which controls the storage of heat and carbon in the ocean, but is inadequately represented in current climate models. The anticipated outcome of the project is an enhanced, global-ocean model incorporating an accurate description of turbulent mixing. This should provide significant benefits to the Australian community by improving the accuracy of future climate predictions.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
Ocean response to tropical cyclone forcing on the Australian North West Shelf. Tropical cyclones are a major hazard for the offshore oil and gas industry. This project will develop the ability to predict the ocean response to tropical cyclones, leading to a paradigm shift in the way industry designs and operates both present and future offshore projects.
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
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 e ....Hydrodynamics of Fringing Reef Systems.

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
The stability and predictability of the Southern Hemisphere coupled ocean-atmosphere climate system. Our ability to adapt to and manage the effects of a changing climate is limited by our understanding of the ocean's response to changes in the atmospheric circulation. This project will establish the basis for the predictability of the climate system and provide state-of-the-art forecasts for climate adaptation.
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. With observations from the continental slope region of ....Benthic Processes and Oceanic 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. 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

Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next ten-fifty years. Research into climate change and climate variability is thus highly significant for Australia, and will underpin efforts to protect our biodiversity and ensure the nation's environmental sustainability. We propose to launch a major new study of the stability of the Southern Ocean's thermohaline circulation and its role in global climate. This work could have significant long-term benefits for those sectors of society sensitive to shifts in climate; including agriculture, energy, freshwater supply, health, and tourism.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
