Hydrogen: an overlooked intermediate during anoxia in permeable sediments. This project aims to quantify the respiratory pathways and the importance of hydrogen as an intermediate during anoxia in permeable (sand) sediments which dominate our coastline. It is anticipated the findings of this project will enable more accurate fundamental understanding of sediment diagenetic processes which control nutrient regeneration and loss pathways in the marine environment. This will enable better manageme ....Hydrogen: an overlooked intermediate during anoxia in permeable sediments. This project aims to quantify the respiratory pathways and the importance of hydrogen as an intermediate during anoxia in permeable (sand) sediments which dominate our coastline. It is anticipated the findings of this project will enable more accurate fundamental understanding of sediment diagenetic processes which control nutrient regeneration and loss pathways in the marine environment. This will enable better management of these environments in the face of increasing coastal population growth.Read moreRead less
Mantle evolution and the origin of Earth's atmosphere. This project aims to investigate Earth’s early evolution and the origin of our atmosphere. Using state-of-the-art instrumentation the project will measure noble gas and tungsten isotopes in unique volcanic glasses that record the composition of the Earth’s mantle. These measurements are expected to clarify the relationship between the formation of Earth’s atmosphere, mantle and core, and to generate new knowledge about convective currents ....Mantle evolution and the origin of Earth's atmosphere. This project aims to investigate Earth’s early evolution and the origin of our atmosphere. Using state-of-the-art instrumentation the project will measure noble gas and tungsten isotopes in unique volcanic glasses that record the composition of the Earth’s mantle. These measurements are expected to clarify the relationship between the formation of Earth’s atmosphere, mantle and core, and to generate new knowledge about convective currents in the modern mantle. The project aims to train the next generation of Earth scientists and to provide new knowledge to assist in overcoming the challenges in mitigating climate change and sustaining a resource-based economy.Read moreRead less
