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
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.

Australian membership of the International Ocean Discovery Program:
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

Island resilience to tropical cyclones and rising sea levels. This project aims to produce a dynamic model to address the global problem of low-lying island inundation following high-energy events, such as tropical cyclones and storm surges. These events threaten coastal habitats and biodiversity, and in worst cases, displace human populations. The model will identify islands at risk to inundation thereby enabling governments to adopt appropriate mitigation and/or adaptation strategies to impr ....Island resilience to tropical cyclones and rising sea levels.

U/Th dating of coral mortality and recovery rates in the Great Barrier Reef. This project aims to use high-efficiency U-Th geochronology and palaeoecology to identify past coral mortality events and community changes in the inshore Great Barrier Reef (GBR) and quantify subsequent recovery rates across a water quality gradient. These records will then be linked to natural and human impacts, especially since European settlement.

New Riversleigh: Bridging chasms in the Neogene of Australia. This project aims to investigate the evolution of Australia’s animals in the late Miocene, 10 - 5 million years ago. The team’s discovery of a remote fossil field west of and larger than the Riversleigh World Heritage Area opens a window into Australia’s past, linking those of Australia's older lush rainforest communities to those of its drier, more modern habitats.

This project aims to investigate the evolution of Australia’s animals in the late Miocene, 10 - 5 million years ago. The team’s discovery of a remote fossil field west of and larger than the Riversleigh World Heritage Area opens a window into Australia’s past, linking those of Australia's older lush rainforest communities to those of its drier, more modern habitats. Radiometric dates indicate that sediments in this vast area are late Miocene in age. This project will reveal how Australia’s wildlife responded to one of the world’s biggest climate changes and help better anticipate what will be required to ensure its survival into the future. Benefits include enhanced understanding about long-term biota/climate interactions and significant additions to Australia’s unique, internationally significant palaeontological artefacts.Read moreRead less
