Eddy-resolving global ocean-sea ice modelling. This project aims to develop a world-class global ocean-sea ice model framework through a nationwide consortium. The resulting high resolution models are expected to provide the foundation for the next decade of Australian ocean-sea ice modelling capacity. This research should lead to improved ocean and sea ice prediction, ocean reanalyses, and climate projections, enhancing Australia's capacity to predict the ocean state on timescales of days to decades. This is expected to yield efficiencies in shipping, marine search and rescue and naval operations, and increase the accuracy of projected future changes in climate, sea level, ocean ecosystems and the cryosphere.Read moreRead less

This project aims to bring the next generation of ocean-sea ice models to Australia and configure the models for our local priorities. The ultimate goal is to create a new coupled ocean-sea ice model for Australia that includes surface waves and biogeochemistry.

Ocean and sea ice models are used for predicting future ocean and climate states, and for climate process research. This project aims to bring the next generation of ocean-sea ice models to Australia and configure the models for our local priorities. The ultimate goal is to create a new coupled ocean-sea ice model for Australia that includes surface waves and biogeochemistry. The model will be optimised and evaluated on Australian facilities, and released for community use. These developments underpin future ocean state forecasts, sea ice forecasts, wave forecasts, decadal climate prediction and climate process studies. The project will benefit search and rescue, Defence and shipping operations, and will enhance future climate projections.Read moreRead less
Unraveling ocean mixing and air-sea forcing along the Indo-Pacific exchange. This project aims to collect unprecedented observations and develop high resolution model simulations to examine changes in the Indonesian Throughflow (ITF) north of Australia. This project expects to develop new knowledge of ocean-atmosphere interactions along the path of the ITF from the Pacific to the Indian Ocean, which are the powerhouse that drives changes in winds and rainfall around Australia and the entire Indo ....Unraveling ocean mixing and air-sea forcing along the Indo-Pacific exchange. This project aims to collect unprecedented observations and develop high resolution model simulations to examine changes in the Indonesian Throughflow (ITF) north of Australia. This project expects to develop new knowledge of ocean-atmosphere interactions along the path of the ITF from the Pacific to the Indian Ocean, which are the powerhouse that drives changes in winds and rainfall around Australia and the entire Indo-Pacific region. Expected outcomes include a 1000-fold increase in the observations of mixing in the Indonesian seas and new understanding of the ocean-atmosphere processes that control water property change along the ITF. This should lead to strong improvement in the skill of climate forecast models in the Australian region.Read moreRead less
Distribution of ocean heat uptake and its implications for sea level and climate change. Increasing sea levels and ocean temperatures provide critical evidence of long term warming of the climate system. This project will investigate geographical changes in the vertical distribution of heat uptake by the ocean and contribution to sea level changes, including understanding of physical mechanisms and the role of human activity and other natural external and internal factors. The expected outcomes ....Distribution of ocean heat uptake and its implications for sea level and climate change. Increasing sea levels and ocean temperatures provide critical evidence of long term warming of the climate system. This project will investigate geographical changes in the vertical distribution of heat uptake by the ocean and contribution to sea level changes, including understanding of physical mechanisms and the role of human activity and other natural external and internal factors. The expected outcomes will contribute to place more rigorous constraints on the likelihood of future warming and sea level rise projections, and are aligned with scientific deliverables required to address key questions in support of Australia’s climate change policy.Read moreRead less
Understanding spread in sea level rise projections. This project aims to investigate changes in water properties and ocean circulation mechanisms leading to intermodel spread in sea-level projections. Sea-level rise projections for this 21st century largely disagree in magnitude and spatial changes between climate models, particularly in hotspots. The expected outcomes will contribute towards more rigorous constraints on the likelihood of future warming and sea-level rise projections, and are al ....Understanding spread in sea level rise projections.

The expected outcomes will contribute towards more rigorous constraints on the likelihood of future warming and sea-level rise projections, and are aligned with scientific deliverables required to address key questions in support of Australia’s climate change policy. They are also aligned with international scientific deliverables in support of the World Climate Research Programme Grand Challenge on Regional Sea Level Change and Coastal Impacts.Read moreRead less
Observations of remarkable eastward flows in the South Indian Ocean. The Indian Ocean drives much of the variability of Australian weather and rainfall and is rapidly evolving. Innovative new observations of remarkable eastward flows in the South Indian Ocean will be combined with models to understand these circulations in a region that has significant economic value for Australia.

Risks of rapid ocean warming at the Antarctic continental margin. This project aims to comprehensively understand the interconnected processes by which oceanic heat is circulated towards Antarctica. The risk of rapid ocean warming at the Antarctic margin is profound, with change already detected via deep ocean warming, land-ice melt, and ice shelf collapse. Yet this region remains poorly understood, with only limited observations due to both a harsh environment and a lack of standard data stream ....Risks of rapid ocean warming at the Antarctic continental margin. This project aims to comprehensively understand the interconnected processes by which oceanic heat is circulated towards Antarctica. The risk of rapid ocean warming at the Antarctic margin is profound, with change already detected via deep ocean warming, land-ice melt, and ice shelf collapse. Yet this region remains poorly understood, with only limited observations due to both a harsh environment and a lack of standard data streams. This project will use high-resolution global and regional ocean/sea-ice models to examine mechanisms for rapid warming of Antarctic continental shelf waters via both large-scale drivers and fine-scale processes, including mesoscale eddies, tide-topography interactions, and bottom boundary flows. This work will better constrain future rates of ice melt around Antarctica by providing vital knowledge of the ocean processes, dynamics, and feedbacks relating to warm water intrusion onto the Antarctic continental shelf.Read moreRead less
How topography brakes the Antarctic Circumpolar Current. This project aims to observe and simulate the mechanisms that slow the Antarctic Circumpolar Current. The Southern Ocean winds have increased over the last two decades while the transport of the world’s largest current remains steady or slightly decreasing. A possible explanation is negative feedback mechanisms between the winds and transport of the Antarctic Circumpolar Current. This project will observe how eddies carry momentum from the ....How topography brakes the Antarctic Circumpolar Current. This project aims to observe and simulate the mechanisms that slow the Antarctic Circumpolar Current. The Southern Ocean winds have increased over the last two decades while the transport of the world’s largest current remains steady or slightly decreasing. A possible explanation is negative feedback mechanisms between the winds and transport of the Antarctic Circumpolar Current. This project will observe how eddies carry momentum from the wind down to the sea floor and accelerate the deep currents that drag against the rough bottom to put the brakes on this current. Since this current affects Australian rainfall patterns and agricultural output, findings could inform public policy.Read moreRead less
