Summary
Linking seismic structure to geodynamic processes beneath Australasia. This project aims to understand the relationship of mantle discontinuities beneath the Australian tectonic plate to mantle convection processes. Subducting slabs stagnate at different depths in the mantle, but the reason is not known. The Australian plate has complex boundaries which exhibit a range of subduction behaviours, making it an ideal location to study convection mechanisms. The project will use specialised seismic s ....Linking seismic structure to geodynamic processes beneath Australasia. This project aims to understand the relationship of mantle discontinuities beneath the Australian tectonic plate to mantle convection processes. Subducting slabs stagnate at different depths in the mantle, but the reason is not known. The Australian plate has complex boundaries which exhibit a range of subduction behaviours, making it an ideal location to study convection mechanisms. The project will use specialised seismic stations for detailed studies beneath New Zealand and Indonesia. The goal is to determine the relationship between seismic observations and geodynamical processes beneath Australasia, and understand how deeper mechanisms influence seismic activity and earthquake hazard at Earth's surface. Such detailed observations will help us to understand processes at the Earth's surface, with implications for earthquake hazard.Read moreRead less
A new Journey to the Earth's Inner Core: a Planet Within a Planet. This project aims to address critical unsolved problems in global geophysics by probing the structure and dynamics of the inner core, the Earth’s time capsule. It focuses on elucidating the inner core’s nature with the improved tomographic images, critically testing our current understanding of how the inner core is assembled and grows, its thermodynamic state, crystallographic structure, and connection with the Earth’s upper lay ....A new Journey to the Earth's Inner Core: a Planet Within a Planet. This project aims to address critical unsolved problems in global geophysics by probing the structure and dynamics of the inner core, the Earth’s time capsule. It focuses on elucidating the inner core’s nature with the improved tomographic images, critically testing our current understanding of how the inner core is assembled and grows, its thermodynamic state, crystallographic structure, and connection with the Earth’s upper layers and geomagnetic field. Answering these questions can have far-reaching consequences for the current knowledge of fundamental geophysics. Expected benefits include training students and researchers in geophysics and data processing, contributing to a skilled STEM workforce and creating leadership for Australia.Read moreRead less
