High resolution warm ocean records from laminated sediment. This project will produce environmental records during ocean warming events in the geologic past to reveal processes associated with warm oceans similar to those anticipated in the coming century. New Australian technology allows investigation of sediment records at unprecedented time resolution providing insight into processes operating on societally relevant time scales of decades to centuries.

This project will produce environmental records during ocean warming events in the geologic past to reveal processes associated with warm oceans similar to those anticipated in the coming century. New Australian technology allows investigation of sediment records at unprecedented time resolution providing insight into processes operating on societally relevant time scales of decades to centuries. This work will open an archive of climate information revealing feedback, thresholds and tipping points from past events previously inaccessible because of technical and conceptual limitations. It will provide critical inputs into models predicting future climate and to illuminate the risks and compensating feedbacks occurring with warming.

Summary
A world-class rock magnetic facility to support Australian palaeomagnetic and environmental research. Magnetic properties of rocks and environmental particles provide information about a vast range of geological and environmental processes. We propose to develop a facility that will enable detection and interpretation of these magnetic signals to aid understanding of climate change, mineral exploration, and the geological development of Australia.
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
Dynamics of carbonate sands and morphodynamics of coral reef environments. Coral reefs are mainly composed of mobile sedimentary deposits that influence the living regions of the coral reefs. Using sites on Australia's Great Barrier Reef, the project will learn how, why and how fast sand advances, and will predict how these processes will change in response to predicted rises in sea levels.

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
Novel dating methods for marine sediments of relevance to determining past climate changes. Future climate change is a subject of enormous contemporary interest with economic and social implications for much of humanity.

Future climate change is a subject of enormous contemporary interest with economic and social implications for much of humanity. Accurate knowledge of past climates is, however, crucial to understanding how the global climate will evolve into the future. This proposal aims to develop novel methods for dating marine sediments using cosmogenic isotopes, in order to extract the palaeoclimatic signals that are locked into these sediments. We will concentrate on the Southern Ocean which plays a crucial role in the world's climate. This proposal will also contribute to Australia's international obligation to conduct research in this critical area.Read moreRead less

This project is for a 5-year membership of the International Ocean Discovery Program, the world’s largest collaborative research program in earth and ocean sciences addressing international priorities. The program conducts seagoing coring expeditions and monitoring of instrumented boreholes to study the history and current activity of the Earth, recorded in sediments and rocks below the seafloor. The program’s aims include understanding past global environments on multiple time scales, the deep biosphere, plate tectonics, occurrence and distribution of resources, and generation of hazards. Several multinational expeditions are scheduled and planned in our marine jurisdiction and within the Australasian region. Read moreRead less
Beach Erosion and Recovery: Quantifying the Hazard. Coastal erosion is confronting societies and the natural environment. The economic value in Australia of built assets at risk includes roads ($60 billion), commercial buildings ($81 billion) and homes ($63 billion). Hard engineering entire coastlines is rarely feasible, with beaches providing the best coastal defence along the great majority of sandy coastlines. But how wide should a buffer zone be to provide adequate protection from storms? An ....Beach Erosion and Recovery: Quantifying the Hazard. Coastal erosion is confronting societies and the natural environment. The economic value in Australia of built assets at risk includes roads ($60 billion), commercial buildings ($81 billion) and homes ($63 billion). Hard engineering entire coastlines is rarely feasible, with beaches providing the best coastal defence along the great majority of sandy coastlines. But how wide should a buffer zone be to provide adequate protection from storms? And critically, how reliable are the present modelling tools used to predict this, and can they be improved? Underpinned by innovative field observations to fill fundamental knowledge gaps, this project aims to deliver advanced understanding and the best available solution to storm erosion prediction.Read moreRead less

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
