Summary
Mixing hot spots in the Southern Ocean: processes, parameterisations and climate impacts. The Southern Ocean plays a critical role in the uptake of heat and carbon dioxide from the atmosphere into the deep ocean. This uptake depends strongly on mixing processes due to ocean eddies, which are especially important in regions of steep topography, leading to localised mixing hot spots. These ocean eddies have scales of 10-100km and therefore can not be resolved in current global climate models. This ....Mixing hot spots in the Southern Ocean: processes, parameterisations and climate impacts. The Southern Ocean plays a critical role in the uptake of heat and carbon dioxide from the atmosphere into the deep ocean. This uptake depends strongly on mixing processes due to ocean eddies, which are especially important in regions of steep topography, leading to localised mixing hot spots. These ocean eddies have scales of 10-100km and therefore can not be resolved in current global climate models. This project will examine these mixing processes using a combination of observations and innovative modelling approaches. This knowledge will be used to improve the representation of eddy processes in state-of-the-art climate models, which will ultimately allow Australia to more effectively respond to the challenge of climate change.Read moreRead less

This project aims to expand Australia's capacity to do high-impact innovative climate, weather and oceanographic science. 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
The Southern Ocean Meridional Overturning Circulation: New observations of vertical mixing. The Southern Ocean and Antarctic Circumpolar Current (ACC) play profound roles in Australian and global climate. However, we know little about how they will be affected by global warming. New velocity observations will tell us how the vertical mixing that contributes to the meridional overturning circulation, and ACC strength, change with the seasons and from year to year. The observations will also gi ....The Southern Ocean Meridional Overturning Circulation: New observations of vertical mixing. The Southern Ocean and Antarctic Circumpolar Current (ACC) play profound roles in Australian and global climate. However, we know little about how they will be affected by global warming. New velocity observations will tell us how the vertical mixing that contributes to the meridional overturning circulation, and ACC strength, change with the seasons and from year to year. The observations will also give us a better understanding of the oceanic and atmospheric processes that drive these changes. This new information will allow climate models to be better constrained so they can more accurately predict changes to Australian and global climate.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.

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
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

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

Our capacity to assess the threat of climate change is undermined by an unacceptable level of uncertainty in the understanding and modelling of regional climates. The Centre will undertake world-class research targeting identified weaknesses in the physical, chemical and biological components of the climate system. We will engage and nurture graduate students and postdoctoral follows through a program of graduate training and mentoring to permanently transform our understanding of climate systems science particularly for the Australian region. The key outcome will be a dramatic enhancement in national capacity to understand and project the scale of future regional climate change.Read moreRead less
