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
Southern Ocean productivity and carbon dioxide (CO2) exchange under current and future climate regimes. 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.

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

Connecting big data with high performance computing for climate science: The ARC Centre of Excellence for Climate System Science is a key user of the National Computational Infrastructure facility (NCI). This research requires massive data integrated with high performance computing in an operational facility. Fast disk capacity that is simultaneously connected to NCI long-term storage, cloud and high performance computing severely limits use of the NCI. To resolve this limitation, 1.7 petabytes of storage will be installed to transform the efficiency of the facility. This will enable more ambitious science to be undertaken. This investment will be used to launch a transformation from petascale to exascale problems and communicate the lessons learned to other research communities in Australia.Read moreRead less
Wave-ice models of Antarctic sea ice. This project aims to design and execute autonomous observations above (unmanned aerial vehicles), below (autonomous underwater vehicles) and within (wave-ice interaction buoys) sea ice on international Antarctic research voyages. The project intends to advance the parameterisation of wave-ice interaction, critical to the seasonal advance and retreat of Antarctic sea ice, in climate models that do not reproduce the observed trends in regional Antarctic sea ic ....Wave-ice models of Antarctic sea ice. This project aims to design and execute autonomous observations above (unmanned aerial vehicles), below (autonomous underwater vehicles) and within (wave-ice interaction buoys) sea ice on international Antarctic research voyages. The project intends to advance the parameterisation of wave-ice interaction, critical to the seasonal advance and retreat of Antarctic sea ice, in climate models that do not reproduce the observed trends in regional Antarctic sea ice extent. The project expects to improve prediction of sea ice’s responses and feedbacks to changes in ocean and atmospheric forcing around the Southern Ocean. This work should place Australia at the forefront of polar climate research. Greater accuracy in climate projections will help to optimise the balance between human populations, economic growth and environmental protection in an uncertain future.Read moreRead less

Science of this kind relies on massive data coupled to computationally highly intensive and complex analysis. Therefore, the project will purchase fast disk storage and install it at the National Computing Infrastructure. It is anticipated that the project will benefit the nation through better understanding of the climate system, including extremes; improvements in our capacity to make predictions; and through applications of the science to forecasting, the management of resources among other many other things.Read moreRead less
Changes in the ocean's biological pump: innovative models and diagnostics. This Project aims to quantify how the ocean’s biological pump, which exports newly formed organic matter into the ocean interior, responds to environmental change. The biological pump is a key control on the global carbon and oxygen cycles, and hence on the viability of marine life. New, efficient numerical models will be developed and analysed with highly innovative mathematical methods. Expected outcomes are optimised .... Changes in the ocean's biological pump: innovative models and diagnostics. This Project aims to quantify how the ocean’s biological pump, which exports newly formed organic matter into the ocean interior, responds to environmental change. The biological pump is a key control on the global carbon and oxygen cycles, and hence on the viability of marine life. New, efficient numerical models will be developed and analysed with highly innovative mathematical methods. Expected outcomes are optimised predictive models and a new understanding of the possible future evolutions of the ocean carbon cycle, acidification, and oxygenation. This should provide significant benefits such as predictions of future ocean health, identification of processes that are sensitive to change, and strategies for marine resource management.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.
