Mineral Physics of the Earth's Core. Most information on the nature of Earth's core properties has come from teleseismic studies, which detect weak earthquake-wave signals that have traversed the Earth's deepest interior. These studies have revealed several unusual and enigmatic phenomena in the core, but interpretation of these observations must rely on mineral-physics data on the materials of the core (e.g. iron-based alloys). This project will create a unique world-class ultra-high pressure l ....Mineral Physics of the Earth's Core.

These studies have revealed several unusual and enigmatic phenomena in the core, but interpretation of these observations must rely on mineral-physics data on the materials of the core (e.g. iron-based alloys). This project will create a unique world-class ultra-high pressure laboratory to obtain such data. By defining the composition and mineralogy of Earth's core, it will place Australia in the forefront of this exciting research field, and will also represent a major national resource for the study of novel materials at extreme conditions.Read moreRead less
The behaviour of geochemical tracers during differentiation of the Earth. This project is aimed at providing fundamental data which Earth Scientists will use to understand the processes by which the Earth separated into its chemically-distinct layers (core, mantle, crust, atmosphere, oceans) and to determine the nature of the continuing interactions between the surface environment in which we live and the deep interior. It will provide training in modern high temperature-high pressure materials- ....The behaviour of geochemical tracers during differentiation of the Earth.

Summary
A Gigabit per second Data Recording System for Geodesy and Astronomy. We plan to acquire a gigabit per second digital data recorder for geodesy and astronomy. We will develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems. We will estimate motion at sites from the combination of VLBI, GPS, gravity and tide gauge data for geodynamic ef ....A Gigabit per second Data Recording System for Geodesy and Astronomy. We plan to acquire a gigabit per second digital data recorder for geodesy and astronomy. We will develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems. We will estimate motion at sites from the combination of VLBI, GPS, gravity and tide gauge data for geodynamic effects, such as post-glacial rebound and tectonic motion and global mean sea level change.
We will increase the density of southern radio sources used to define the International Celestial Reference Frame and investigate their structure and evolution. We will make high time resolution observations of young pulsars to study the phenomena of pulsar glitches and aid in the understanding of neutron star interiors.Read moreRead less
Solidification, Channel Formation and Thermal Erosion In Lava Flows. This project will elucidate the complex dynamics that control the cooling rates and advance rates of lava flows.
