This project will contribute to Australian ocean science expertise in key areas of data synthesis, satellite oceanography and the understanding of marine ecosystems' response to climate change. Collaborations will be developed and strengthened among Australian research institutions, and between Australia and the United States. The focus of the research is the Southern Ocean, which impacts global climate, and on which Australia's southern coastal ecosystems depend. The expertise and techniques developed will have application to other Australian regional seas.Read moreRead less
Eddies: The key to understanding Southern Ocean carbon cycling. This project plans to observe an eddy in the Southern Ocean for three weeks, to understand how its circulation affects ocean productivity and the exchange of carbon dioxide between the ocean and atmosphere. Ocean eddies are like small high and low pressure weather systems which spin either clockwise or anticlockwise, are about 100–200 kilometres across and several hundred metres deep. Eddies are important because they generate verti ....Eddies: The key to understanding Southern Ocean carbon cycling. This project plans to observe an eddy in the Southern Ocean for three weeks, to understand how its circulation affects ocean productivity and the exchange of carbon dioxide between the ocean and atmosphere. Ocean eddies are like small high and low pressure weather systems which spin either clockwise or anticlockwise, are about 100–200 kilometres across and several hundred metres deep. Eddies are important because they generate vertical currents that move nutrients and carbon dioxide up and down. Expected project outcomes will include a better understanding of carbon cycling in an ocean region that is central to the climate of Australia and the rest of the planet.Read moreRead less
Coupled physical and biogeochemical dynamics on the Australian North West Shelf. Information regarding the natural function of the Australian North West Shelf is urgently required to sustainably manage the often conflicting uses of the region. This project will study the role of ocean processes in driving ocean productivity on the North West Shelf and determine the impact of projected climate variability.

Dust to the ocean: Does it really increase productivity? This project aims to investigate the relationship between dust deposition and marine productivity. This project will quantify dust deposition to the ocean and its chemical and ecological impact by using new geochemical techniques and novel approaches with autonomous ocean sensors. Expected outcomes of this project include improved estimates of dust deposition to the ocean and the development of globally-applicable methods for quantifying t ....Dust to the ocean: Does it really increase productivity? This project aims to investigate the relationship between dust deposition and marine productivity. This project will quantify dust deposition to the ocean and its chemical and ecological impact by using new geochemical techniques and novel approaches with autonomous ocean sensors. Expected outcomes of this project include improved estimates of dust deposition to the ocean and the development of globally-applicable methods for quantifying the link between dust and biology using profiling floats. This should provide significant benefits such as improved dust models used to predict future changes in nutrient deposition, with implications for predicting future ocean fish production and carbon uptake.Read moreRead less
The role of Eastern Antarctic polynyas in global ocean circulation. This project aims to study Antarctic polynyas, an important, but poorly observed marine habitat, which profoundly influence the global climate. The major water masses of the world's oceans are formed there, making a large contribution to the ocean heat and carbon dioxide uptake. This study will collect data on ocean properties to 2000m from polynyas in eastern Antarctica throughout the Antarctic winter. The outcomes will be the ....The role of Eastern Antarctic polynyas in global ocean circulation.

This study will collect data on ocean properties to 2000m from polynyas in eastern Antarctica throughout the Antarctic winter. The outcomes will be the provision of data of critical importance to oceanographic and climate studies.Read moreRead less
Hot iron: Are submarine volcanoes important for Southern Ocean iron supply? The scarcity of iron limits biological productivity and carbon uptake in the nutrient rich waters of the Southern Ocean. This project will explore for the first time the role of undersea "hot spot" volcanoes in supplying iron to surface waters, thus linking the solid earth and the biosphere. The project will measure iron abundance, reactivity and nutritional value in buoyant plumes emanating from vents near Heard/McDonal ....Hot iron: Are submarine volcanoes important for Southern Ocean iron supply? The scarcity of iron limits biological productivity and carbon uptake in the nutrient rich waters of the Southern Ocean. This project will explore for the first time the role of undersea "hot spot" volcanoes in supplying iron to surface waters, thus linking the solid earth and the biosphere. The project will measure iron abundance, reactivity and nutritional value in buoyant plumes emanating from vents near Heard/McDonald Islands, Australia's only active volcanoes. The project aims to estimate the hydrothermal contribution to regional biological productivity and extrapolate to the whole Southern Ocean. Successful outcomes will benefit Australia by identifying iron sources that govern productivity and carbon uptake of an economically important ecosystem.Read moreRead less
