Next-generation ocean current forecasting to improve maritime safety . This project aims to measure upper ocean currents at scales of 10-100 km in Australia's marine estate using pioneering satellite radar technology. The Surface Water and Ocean Topography (SWOT) mission will map currents at 10 times the resolution of present-day satellites and revolutionise our understanding of ocean dynamics.

This project aims to measure upper ocean currents at scales of 10-100 km in Australia's marine estate using pioneering satellite radar technology. The Surface Water and Ocean Topography (SWOT) mission will map currents at 10 times the resolution of present-day satellites and revolutionise our understanding of ocean dynamics. Expected outcomes include validation of SWOT data in Australian waters and merging this data into Bureau of Meteorology ocean models. Downstream benefits include improved ocean forecasts for maritime safety, search-and-rescue, spill modelling, and marine conservation. At the same time, the project will build sovereign capability in emerging remote sensing technology with a legacy beyond the life of the SWOT mission.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
Coupling tropical cyclone and climate physics with ocean waves. It is argued that without accounting for the wave effects directly, the physics of large-scale air-sea interactions is inaccurate and incomplete. The project will introduce explicit coupling of large-scale atmospheric and oceanic phenomena with the physics of surface waves which should lead to improved predictions of tropical cyclones and climate.
Atmospheric CO2, global temperature, and surface ocean acidity response to fossil carbon burning - insights from an ancient analogue. Sequestration of anthropogenic CO2 emissions by the oceans and the impacts of resulting ocean acidification and greenhouse warming upon marine ecosystems are vital to understanding the course of future environmental change. This research will improve knowledge of the biological and chemical responses in the ocean to past changes in atmospheric CO2 levels and incre ....Atmospheric CO2, global temperature, and surface ocean acidity response to fossil carbon burning - insights from an ancient analogue. Sequestration of anthropogenic CO2 emissions by the oceans and the impacts of resulting ocean acidification and greenhouse warming upon marine ecosystems are vital to understanding the course of future environmental change. This research will improve knowledge of the biological and chemical responses in the ocean to past changes in atmospheric CO2 levels and increased ocean acidity. This will assist in predicting the consequences of different fossil fuel burning scenarios for climate and marine life, especially the future viability of organisms like corals, molluscs, and calcareous plankton that underpin key tourism and marine production systems.Read moreRead less

DEEP SEA CORALS AS HIGH RESOLUTION RECORDERS OF SOUTHERN OCEAN NUTRIENT CHEMISTRY AND CIRCULATION. There is compelling evidence that the Earth has been warming dramatically since the end of the 19th century as a consequence of increasing atmospheric CO2. This study aims to understand the long-term role of the Southern Ocean as a 'store-house' for CO2, and its significance in controlling changes in the Earth's climate. We will use coral skeletons from the deep oceans as archives of ocean circu ....DEEP SEA CORALS AS HIGH RESOLUTION RECORDERS OF SOUTHERN OCEAN NUTRIENT CHEMISTRY AND CIRCULATION. There is compelling evidence that the Earth has been warming dramatically since the end of the 19th century as a consequence of increasing atmospheric CO2. This study aims to understand the long-term role of the Southern Ocean as a 'store-house' for CO2, and its significance in controlling changes in the Earth's climate. We will use coral skeletons from the deep oceans as archives of ocean circulation and nutrient levels. This information will help unravel how biological activity in the Southern Ocean has responded during previous episodes of climate change, and how this has controlled the levels of CO2 in the Earth's atmosphere. This will provide a better understanding of greenhouse warming and its effect on our future climate.Read moreRead less

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

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
