How the Earth moves: Developing a novel seismological approach to map the small-scale dynamics of the upper mantle. The concept of small-scale convection currents from about 100-400 km below the Earth’s surface is a model proposed to explain the origins of intraplate volcanoes and mountains. However, direct evidence for the physical reality of small-scale convection cells is generally weak. This project will develop a novel seismological approach combining both ambient noise and earthquake data ....How the Earth moves: Developing a novel seismological approach to map the small-scale dynamics of the upper mantle. The concept of small-scale convection currents from about 100-400 km below the Earth’s surface is a model proposed to explain the origins of intraplate volcanoes and mountains. However, direct evidence for the physical reality of small-scale convection cells is generally weak. This project will develop a novel seismological approach combining both ambient noise and earthquake data that can image such small-scale upper mantle convection. The outcomes of this project will help to fill the gap left in the Plate Tectonic paradigm by its inability to explain intraplate geological activity (volcanoes, earthquakes, mountains), which would be a significant step towards unifying conceptual models about how the Earth works.Read moreRead less

A fully automated, fully shielded palaeomagnetic system: This project aims to establish the first fully automated and magnetically fully shielded superconducting palaeomagnetic data acquisition system in Australia. Palaeomagnetism is a key research field that has applications to a broad range of pure and applied geoscience disciplines. Australia has been a world leader in this field, including the application of palaeomagnetism to both global and regional tectonic studies. Palaeomagnetic studies demand a labour-intensive process of treating and measuring a large number of samples. The system will significantly enhance the efficiency and accuracy of palaeomagnetic analysis, and thus enhance Australia's research capacity in this and related research fields.Read moreRead less
Down under down under: using multi-scale seismic tomography to image beneath Australia's Great Artesian Basin. Seismic arrays will be deployed in the Great Artesian Basin to image the crust and mantle using distant earthquake and ambient noise sources. This will answer fundamental questions about the tectonic evolution of eastern Australia and elucidate the structure of a region containing significant deep Earth resources.
