Bridging the land–sea divide to ensure food security under climate change. This project aims to comprehensively evaluate ocean-based food solutions to meet food security needs under climate change. It will resolve a critical blind spot in current plans that isolate land and sea food systems and neglect their interdependencies. Combining global models and data, it will assess the constraints of ocean-based food solutions by anticipating and accounting for land-sea links including: agricultural ru ....Bridging the land–sea divide to ensure food security under climate change. This project aims to comprehensively evaluate ocean-based food solutions to meet food security needs under climate change. It will resolve a critical blind spot in current plans that isolate land and sea food systems and neglect their interdependencies. Combining global models and data, it will assess the constraints of ocean-based food solutions by anticipating and accounting for land-sea links including: agricultural runoff, shared feed resources for farmed animals, and trade-offs for biodiversity and climate mitigation. It will deliver a major leap in our capacity to undertake holistic ecosystem assessment of future food production pathways. Benefits will include integrated food–biodiversity–climate policies for Australia and the world.Read moreRead less

Through a fusion of innovative analyses of observations and fundamental science advances, alongside the development of ultra-high resolution climate models, the Centre looks to address climate science’s grand challenge in anticipating the likely weather patterns of a warmer world. The Centre strives to transform climate research by focussing on what matters most to making critical adaptation and mitigation decisions – weather change. The Centre aspires to provide Australia with the knowledge, technology, and human capital for robust evidence-based decision-making in response to future weather changes in our region and to harness weather as a resource.Read moreRead less

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

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
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

This project will adress our lack of confidence in future projections of sea ice around Antarctica by elucidating the mechanisms controlling sea ice in the Southern Ocean.
There is low confidence is current sea ice projections, limiting our ability to predict ice shelf melt and sea level rise.
This project will lead to a detailed understanding of the future of sea ice in the Southern Ocean, improving our understanding of ocean dynamics, ice shelf melt, and sea level rise.
The results from this project will enhance projections of sea ice, and therefore also ice shelf melt and sea level rise. Improved sea level projections will aid policy decisions for coastal communities.Read moreRead less
Multi-model predictions of ecosystem flux under climate change based on novel genetic and image analysis methods. Improving the forecasts of ecosystem shifts must be a key focus of future ecological research if we are to preserve our unique Australian landscapes. Our proposal is of clear benefit to Australia because of the urgent need for integrated methods to predict the cumulative impact of shifts in climate and land use.

Our proposal is of clear benefit to Australia because of the urgent need for integrated methods to predict the cumulative impact of shifts in climate and land use. We will also contribute innovative tools involving genetic and image analysis, and state-of-the-art modelling. The damage modern human societies are inflicting on global environments has led to a great demand for logistically feasible and cost-effective ways to prevent biodiversity loss.Read moreRead less

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
