How do sediments become magnetised? Construction of an empirical-numerical framework. The magnetism of sediments provides information on the past behaviour of the Earth's magnetic field. This project will study sediments from the oceans around Australia to understand how the field was recorded and use this information to construct a new generation of computer models that will provide insights into the physics of the recording process.
Driving a palaeomagnetic revolution: geophysical and environmental signals from magnetic biominerals. Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive geological occurrence. This project proposes to determine: the mechanisms by which ....Driving a palaeomagnetic revolution: geophysical and environmental signals from magnetic biominerals. Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive geological occurrence. This project proposes to determine: the mechanisms by which magnetofossils contribute to sedimentary palaeomagnetic signals; if magnetofossil occurrences provide information about the marine carbon cycle; and, if magnetofossil chemistry can constrain the depth of sedimentary palaeomagnetic signal acquisition. These are major outstanding questions in sedimentary palaeomagnetism.Read moreRead less

Summary
Enabling next-generation earthquake and tsunami early warning. This project aims to develop a new approach for earthquake and tsunami early warning, avoiding many of the limitations currently present in such systems. The project will combine machine learning and artificial intelligence with state-of-the-art geophysical modelling, allowing high-quality real-time prediction of seismic hazards with full uncertainty information. Highlighting opportunities at the interface between geoscience and data ....Enabling next-generation earthquake and tsunami early warning. This project aims to develop a new approach for earthquake and tsunami early warning, avoiding many of the limitations currently present in such systems. The project will combine machine learning and artificial intelligence with state-of-the-art geophysical modelling, allowing high-quality real-time prediction of seismic hazards with full uncertainty information. Highlighting opportunities at the interface between geoscience and data science, the project will stimulate novel approaches, and build Australian research capacity in this area. Expected benefits include improved techniques for geophysical imaging and real-time data analysis, in addition to enhanced capabilities for mitigating the costs associated with seismic activity.Read moreRead less
The dynamics of convection - insights for ocean and climate physics and for solar thermal energy system design. This project will inform our understanding of, and response to, climate change by improving knowledge of ocean circulation and technology for renewable energy generation. The results will lead to better climate prediction models and understanding of ocean CO2 uptake, acidification and sea-level rise, and will help to reduce energy sector emissions.
