Summary
Tracking groundwater variations via 4-dimensional seismic imaging. This project aims to develop an advanced seismic framework to sense subtle subsurface changes related to groundwater variations beneath the Great Artesian Basin. Groundwater storage is subject to climatic and anthropogenic forcing, but modern monitoring tools are not sufficient to capture its detailed response in both time and space. Using novel techniques and extensive seismic recordings, this project expects to generate time-la ....Tracking groundwater variations via 4-dimensional seismic imaging. This project aims to develop an advanced seismic framework to sense subtle subsurface changes related to groundwater variations beneath the Great Artesian Basin. Groundwater storage is subject to climatic and anthropogenic forcing, but modern monitoring tools are not sufficient to capture its detailed response in both time and space. Using novel techniques and extensive seismic recordings, this project expects to generate time-lapse images across the basin in unprecedented resolution to reveal the system's dynamic evolution and a static basin model to aid the interpretation. Potential benefits include improved geophysical techniques for groundwater tracking and enhanced scientific understandings to underpin future groundwater management.Read moreRead less

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

Summary
What's shaking down under? This project aims to determine the underlying cause of recent earthquake activity in central Australia. Of all the stable continents, Australia is surprisingly seismically active, with intra-plate earthquakes occurring relatively frequently. However, these are unpredictable, placing lives and infrastructure at risk. This project offers the opportunity to use a new seismic experiment to improve detection of small events that may warn of a more dangerous earthquake to co ....What's shaking down under? This project aims to determine the underlying cause of recent earthquake activity in central Australia. Of all the stable continents, Australia is surprisingly seismically active, with intra-plate earthquakes occurring relatively frequently. However, these are unpredictable, placing lives and infrastructure at risk. This project offers the opportunity to use a new seismic experiment to improve detection of small events that may warn of a more dangerous earthquake to come, and provide sub-surface imaging of the hidden crustal boundaries and faults that are ultimately responsible. Benefits will include improved hazard assessment, and a new predictive model for exploration that relates regional seismicity, crustal faults, and mineral systems.Read moreRead less

Optimising the use of geophysical data for modelling the Australian crust. This project aims to determine the optimal use of geophysical methods to model the Australian crust in four dimensions.

This project aims to determine the optimal use of geophysical methods to model the Australian crust in four dimensions. These models provide an understanding of the tectonic history of a region and thus its mineral potential. Mineral resources are mostly being found undercover, requiring geophysical data to locate them. This project will combine recent developments in modelling geological uncertainty with data acquired for locating zones of mineralisation. The outcomes will help guide Australian government policy to draw on publicly-available datasets that provide a basis for mineral exploration performed by companies, and supported by research institutions.Read moreRead less

Summary
A new understanding of Antarctic ice melting. Melting of grounded ice in the Antarctic may play a key role in future global sea level rise and Earth's climate system. Ocean-ice interactions governing the rate of melting are not well understood and limited data leads to large uncertainties in the predictions of future melting rates.

Melting of grounded ice in the Antarctic may play a key role in future global sea level rise and Earth's climate system. Ocean-ice interactions governing the rate of melting are not well understood and limited data leads to large uncertainties in the predictions of future melting rates. This project will undertake the first direct numerical simulations examining the complex dynamics of melting of ice-shelves in the presence of convection and turbulence, while translating the results to improve ocean models. By calculating the sensitivity of melting rate to surrounding ocean conditions, the project will develop the knowledge required to better predict future melting rates.Read moreRead less

This project aims to advance research on the internal structure and temporal change in the Antarctic ice sheet by analysing seismic ground motion records of natural sources, including ambient noise. This approach expects to complement existing satellite and airborne methods to resolve glacial structures over large areas and detect changes hidden under snow cover. The intended outcome is new knowledge of the ice sheet’s stratification, its long-term variation due to climate change, and its rapid response to local weather events. The benefits include improving the reliability of ice sheet evolution modelling and sea-level rise prediction, unlocking a polar gateway to study Earth deep interior, and preparing for space missions to icy worlds.
