Summary
Rapid Deployment Seismic Recorders for Interdisciplinary Antarctic Research. We aim to establish an Antarctic-based set of seismic instruments, a mobile facility, to provide data to help predict how ice sheets will evolve and how the continent under the ice sheets will respond to changes in ice load. Our approach to tackling such significant questions is innovative, and makes use of newly available, rapid deployment instruments that may be deployed in ice by a small team with light logistics. ....Rapid Deployment Seismic Recorders for Interdisciplinary Antarctic Research. We aim to establish an Antarctic-based set of seismic instruments, a mobile facility, to provide data to help predict how ice sheets will evolve and how the continent under the ice sheets will respond to changes in ice load. Our approach to tackling such significant questions is innovative, and makes use of newly available, rapid deployment instruments that may be deployed in ice by a small team with light logistics. Outcomes will include maps of sub-ice sediments and 3D images of the deep Earth. The facility will thus enable new knowledge relating to major ice sheets. Interdisciplinary use of the research will benefit Australia through an improved ability to plan for future sea level rise in areas with large coastal populations.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.

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
Understanding the deep driving forces of Earth’s large-scale topography through time. We propose to model the convection of Earth’s mantle linked to tectonic plate motions to unravel their combined influence on the evolution of topography over 550 million years. The project will lead to an understanding of the driving forces of large-scale topography in continental interiors and along their margins through geological time.

Earth’s response to ice unloading: a unique GPS measurement from Antarctica . Earth's response to ice unloading - a unique GPS measurement from Antarctica: This project aims to deploy geophysical equipment including global navigation satellite systems within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660 km).

Earth's response to ice unloading - a unique GPS measurement from Antarctica: This project aims to deploy geophysical equipment including global navigation satellite systems within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660 km). It exploits a globally-unique natural experiment that commenced in 2002 with the break-up of the Larsen B Ice Shelf and which was followed by large-scale ice-mass unloading and rapid surface deformation. New broadband passive seismic and geodetic deformation measurements offer the promise of resolving a dichotomy between laboratory and millennial-scale determinations of Earth rheology through uniquely studying a time-scale mid-way between these extremes, whilst further strengthening Australia's emerging expertise in polar geophysics.Read moreRead less
Establishing the reference frame using astronomical and space-geodetic observations. Australia is increasingly dependent on spatial positioning and spatial data, yet mostly relies upon international agencies and research organisations to provide regular updates of coordinates and reference frame definition used on Earth. Improving the accuracy of the reference frame definition and our understanding of errors in the space-based measurements will provide new insights for studies of the Earth.

Australia is increasingly dependent on spatial positioning and spatial data, yet mostly relies upon international agencies and research organisations to provide regular updates of coordinates and reference frame definition used on Earth. Improving the accuracy of the reference frame definition and our understanding of errors in the space-based measurements will provide new insights for studies of the Earth. The research will yield results in studies of national significance, such as sea level rise, the effects of melting polar regions, and crustal deformation, as well as developing Australia's expertise in exploiting observations of the Earth from space.Read moreRead less
From plume source to hotspot: quantifying mixing in mantle plumes and its implications for the nature of deep-mantle heterogeneity. Mantle plumes are buoyant upwellings that bring hot material from Earth's deep-mantle to the surface, forming volcanic hotspots, like Hawaii. Although extensively studied, the geochemical variations recorded in hotspot lavas have, so far, proved difficult to understand, particularly how they relate to their heterogeneous deep-mantle source. This project aims to use ....From plume source to hotspot: quantifying mixing in mantle plumes and its implications for the nature of deep-mantle heterogeneity. Mantle plumes are buoyant upwellings that bring hot material from Earth's deep-mantle to the surface, forming volcanic hotspots, like Hawaii. Although extensively studied, the geochemical variations recorded in hotspot lavas have, so far, proved difficult to understand, particularly how they relate to their heterogeneous deep-mantle source. This project aims to use state-of-the-art geodynamical models to determine how deep-mantle heterogeneities are transported into a plume and how such heterogeneities are mixed during plume ascent. This will facilitate the linking, for the first time, of geochemical variations at volcanic hotspots to the deep-mantle's thermo-chemical structure, under an Earth-like, fluid-dynamical framework.Read moreRead less
Next-generation tsunami warning. This project generates the science for rapid tsunami forecasts of sufficient accuracy and detail to maintain public confidence in tsunami warnings. It will show how next-generation warning systems can assimilate multi-sensor data to provide probabilistic forecasts enabling emergency managers to make well-informed decisions about imminent tsunamis.
A new generation of palaeomagnetic statistics. This project aims to build on recent advances in statistical inference to develop a new quantitative framework for palaeomagnetism. Palaeomagnetic analysis of Earth's ancient magnetic field helps us to derive plate tectonic reconstructions and to use geomagnetic reversals to date rock sequences. These applications depend on statistical methods that are either flawed or that lack sufficient diagnostic power to be useful for addressing increasingly co ....A new generation of palaeomagnetic statistics.

Palaeomagnetic analysis of Earth's ancient magnetic field helps us to derive plate tectonic reconstructions and to use geomagnetic reversals to date rock sequences. These applications depend on statistical methods that are either flawed or that lack sufficient diagnostic power to be useful for addressing increasingly complex questions. Expected outcomes are an urgently needed new generation of palaeomagnetic statistical analysis methods. The project will provide quantitative tools that will benefit all palaeomagnetic applications across Earth Science and have widespread benefit and impact in academic and industrial research.Read moreRead less

Frequency-dependent seismic properties of cracked and fluid-saturated crustal rocks: a systematic laboratory study. Novel experimental techniques will be used to build a better laboratory-based understanding of the seismic properties of fluid-saturated crustal rocks. The outcome will be an improved capacity to monitor the presence of fluids in diverse situations ranging from geothermal power generation and waste disposal to earthquake fault zones.
