Summary
Assessing the vulnerability of East Antarctica to future warming. This DECRA aims to address major gaps in our understanding of how the Antarctic Ice Sheet will respond to climate change, by enabling critical insights on its sensitivity to past climate warming. The project will apply a suite of geochemical approaches to determine – for East Antarctica’s most vulnerable basin – the extent of ice-sheet loss during past warming, and the impact of glacial meltwater on biological productivity and Sou ....Assessing the vulnerability of East Antarctica to future warming. This DECRA aims to address major gaps in our understanding of how the Antarctic Ice Sheet will respond to climate change, by enabling critical insights on its sensitivity to past climate warming. The project will apply a suite of geochemical approaches to determine – for East Antarctica’s most vulnerable basin – the extent of ice-sheet loss during past warming, and the impact of glacial meltwater on biological productivity and Southern Ocean circulation. New knowledge of how the ice sheet and ocean respond to climate warming, will lead to more reliable projections of future sea-level rise and climate. The DECRA will benefit Australia by providing a strong evidence base for policy decision-making to manage the impact of sea-level rise.Read moreRead less
The Great Barrier Reef in 2100. Our research aims to answer fundamental geomorphic questions about the future of coral reefs, focusing on the Great Barrier Reef (GBR). We will develop cutting-edge, fully open-source numerical models to quantify the eco-morphodynamic evolution of the GBR under IPCC climate-change scenarios. Our geomorphic numerical models will consider biotic/abiotic feedbacks including synergistic effects of multiple stressors such as waves, temperature, acidification and sedime ....The Great Barrier Reef in 2100. Our research aims to answer fundamental geomorphic questions about the future of coral reefs, focusing on the Great Barrier Reef (GBR). We will develop cutting-edge, fully open-source numerical models to quantify the eco-morphodynamic evolution of the GBR under IPCC climate-change scenarios. Our geomorphic numerical models will consider biotic/abiotic feedbacks including synergistic effects of multiple stressors such as waves, temperature, acidification and sediment transport, at individual reef scales. We will model the future of the GBR’s ecosystem-services, allowing for a quantum leap in the geomorphic knowledge and understanding of coral reef ecosystems. Expected outcomes include a gamechanger tool for future management of the GBR.Read moreRead less
The deep-sea carbon reservoir through geological time. Despite being by far the largest carbon reservoir on Earth, deep-sea carbonate and its recycling through the Earth system are the most significant missing links in our knowledge of the global carbon cycle. This project aims to track the evolution of the deep-sea carbon reservoir over the last 150 million years by using recently developed spatio-temporal computational and model-data synthesis tools. The project will provide the first rigorous ....The deep-sea carbon reservoir through geological time. Despite being by far the largest carbon reservoir on Earth, deep-sea carbonate and its recycling through the Earth system are the most significant missing links in our knowledge of the global carbon cycle. This project aims to track the evolution of the deep-sea carbon reservoir over the last 150 million years by using recently developed spatio-temporal computational and model-data synthesis tools. The project will provide the first rigorous quantification of the distribution and volume of carbon in deep-sea carbonate, and its fluxes between the Earth’s surface and interior. It will advance our understanding of the history and rate of carbon dioxide storage and degassing over geological time, and inform public debate on climate change.Read moreRead less

This proposal is for an 18-month membership of the International Ocean Discovery Program (IODP), the world’s largest collaborative research program in Earth and Ocean sciences. The Program studies the history and current activity of the Earth by conducting seagoing coring expeditions and monitoring of instrumented boreholes, using globally unique infrastructure that Australians would otherwise have no access to. Program outcomes include understanding past global environmental change on multiple time scales, the deep biosphere, plate tectonics, formation and distribution of resources, and generation of hazards. These outcomes are paramount to Australia’s national science and research priorities, and societal and economic prosperity.Read moreRead less

Summary
The interplay of tectonics and sea level on carbonate platform evolution. Reefs and carbonate platforms represent the most prolific component of Earth’s carbonate factory on geological timescales. The project will develop a digital community framework for modelling the rise and demise of carbonate platforms on geological timescales. The project will untangle the relative influence of tectonics, dynamic topography from mantle convection, sea level change, climate, and terrestrial sediment runoff ....The interplay of tectonics and sea level on carbonate platform evolution. Reefs and carbonate platforms represent the most prolific component of Earth’s carbonate factory on geological timescales. The project will develop a digital community framework for modelling the rise and demise of carbonate platforms on geological timescales. The project will untangle the relative influence of tectonics, dynamic topography from mantle convection, sea level change, climate, and terrestrial sediment runoff on the growth and drowning of carbonate platforms. The outcomes will identify the environmental conditions that shut down reefs on the scale of the Great Barrier Reef, quantify the carbon storage potential of carbonate platforms, and model the tectonic development of Australia's continental margins in unprecedented detail.Read moreRead less
Deep Atlantic’s role in millennial atmospheric carbon dioxide changes. This project aims to fill in a critical knowledge gap in global carbon cycle research, by generating the first high-resolution deep Atlantic carbonate ion and nutrient records for the last 150,000 years. The project will derive air-sea carbon dioxide (CO2) exchange signals, which permit straightforward evaluation of the deep Atlantic’s role in millennial atmospheric CO2 changes under various climate conditions.

This project aims to fill in a critical knowledge gap in global carbon cycle research, by generating the first high-resolution deep Atlantic carbonate ion and nutrient records for the last 150,000 years. The project will derive air-sea carbon dioxide (CO2) exchange signals, which permit straightforward evaluation of the deep Atlantic’s role in millennial atmospheric CO2 changes under various climate conditions. The intended outcome of this project is to substantially improve our understanding of the mechanisms that govern the global carbon cycle. This should provide significant benefits including the assessment of models used to predict future global warming due to anthropogenic CO2.Read moreRead less
