This project will deliver the most comprehensive investigation of Earth’s oldest known river/lake deposits, uniquely preserved in 2.8 billion-year-old rocks in Western Australia. Using the candidate’s expertise in field investigation in combination with a cutting-edge analytical approach, the project will produce a detailed reconstruction of the ancient lake environment. Similar settings will be explored by NASA's upcoming Mars 2020 rover mission at it's landing site in Jezero Crater. Mission data will be analysed by the candidate, who will guide the selection of samples and address the overarching question of whether microbal life ever existed on Mars.Read moreRead less
Using fossil micrometeorites to examine the ancient Earth environment. This project aims to use fossil micrometeorites to provide fundamental new data on changes in the chemistry of the ancient Earth's upper atmosphere before, during and after the Great Oxidation Event, the most significant atmospheric change in Earth’s history. This would provide insights into variations in the extent of interaction between the upper and lower atmosphere across the Great Oxidation Event.

This would provide insights into variations in the extent of interaction between the upper and lower atmosphere across the Great Oxidation Event. The project will also use these micrometeorites to investigate how the flux, composition and sources of extra-terrestrial material arriving on Earth changed over time.Read moreRead less

Summary
Meteorite fireballs - illuminating the origins of the solar system. Meteorites are ancient rocks, containing a record of what conditions were like when the solar system was young; but to understand that record we need to know where they come from. This project will deliver these data, providing us with a template to understand how our planetary system came into being.
Role of water in earth and planetary evolution. This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth. This project will use new techniques for measuring low abundances of water along with oxygen isotopes, to measure water abundances and oxygen isotopes in meteorites and terrestrial rocks to establish how water was delivered to Earth ....Role of water in earth and planetary evolution. This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth. This project will use new techniques for measuring low abundances of water along with oxygen isotopes, to measure water abundances and oxygen isotopes in meteorites and terrestrial rocks to establish how water was delivered to Earth and to understand how water is geologically recycled. This is expected to have direct bearing on where and how Earth's water originated, how water is retained in mantle and crustal minerals and it will have broad implications for understanding volcanic hazards and formation of ore deposits. This will lead to a new capability for combined water and oxygen isotope analysis in Australian geoscience leading to technological development and commercialisation of instrumentation.Read moreRead less

Summary
A global fireball observatory. This project aims to expand the Desert Fireball Network (DFN) and build a Global Fireball Observatory. Nearly everything known about the origin and evolution of the solar system comes from analysis of meteorite falls, but scientists have almost no constraint on where they come from. This project will address this constraint by tracking hundreds of meteorite falls, and pinpointing each one’s origin in the solar system. Benefits include capitalising on the innovation ....A global fireball observatory. This project aims to expand the Desert Fireball Network (DFN) and build a Global Fireball Observatory. Nearly everything known about the origin and evolution of the solar system comes from analysis of meteorite falls, but scientists have almost no constraint on where they come from. This project will address this constraint by tracking hundreds of meteorite falls, and pinpointing each one’s origin in the solar system. Benefits include capitalising on the innovations and technologies that underpinned the DFN, and leveraging a NASA partnership for administrative support and advanced instrumentation development. Tracking for space situational awareness is also expected to benefit Australian national security.Read moreRead less
Structure of crust on Mars. This project aims to start a new multidisciplinary field linking impact physics and seismology. This project involves numerical modelling of meteoroid impact-induced seismic activity on Mars, using the state-of-the-art hydro-code, a national supercomputing facility, and knowledge built on the meteorite hunting by the Dessert Fireball Network.

Virtually everything we know about the origin and evolution of our solar system comes from analysis of meteorites. But reading the record they contain has proven to be difficult: we have almost no constraint on where they come from. With ARC LIEF support, Australian planetary scientists are leading a consortium of 14 international teams to build a Global Fireball Observatory. The facility, with a unique global footprint, will be complete by end-2019. It will track 100s of meteorite falls, and for each one, pinpoint its origin in the solar system. A NASA partnership will provide administrative support. Curtin University will fund its operation. The proposal here is for a researcher and student who can drive the science program.Read moreRead less
Investigation of the early history of the moon. The project will address outstanding questions related to the early evolution of planets in the solar system, including the earth, by investigating major events that took place on the moon, where the record of early history is preserved exceptionally well. It will test major models describing the chemical evolution of both the moon and earth.
Water in the deep Earth. Water has profound influence on many deep Earth processes ranging from melting to plate movements. Water in deep Earth is replenished by subduction. A significant part of water can be stored in nominally anhydrous minerals, such as olivine, pyroxene and garnet that result from the breakdown of hydrous phases within the subducted lithosphere. The project proposes a combined experimental and analytical project to determine how much water is transported to the deeper mantle ....Water in the deep Earth.

A significant part of water can be stored in nominally anhydrous minerals, such as olivine, pyroxene and garnet that result from the breakdown of hydrous phases within the subducted lithosphere. The project proposes a combined experimental and analytical project to determine how much water is transported to the deeper mantle in these minerals. This project aims to determine the incorporation mechanisms of water into these key minerals and to establish an Australian facility for water determination in minerals that has the sensitivity needed for studying deep Earth materials.Read moreRead less
The seismic significance of water and partial melting in planetary interiors. Novel laboratory techniques will be used to measure the influence of dissolved water on the seismic properties of the deep interiors of Earth and Moon. The outcome will be new insight into the crucial role of water in the formation and subsequent evolution of our dynamic planet and its more quiescent moon.
