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

Summary
Assessing the vulnerability of East Antarctica to future warming. This DECRA aims to address major gaps in our understanding of how the Antarctic Ice Sheet will respond to climate change, by enabling critical insights on its sensitivity to past climate warming. The project will apply a suite of geochemical approaches to determine – for East Antarctica’s most vulnerable basin – the extent of ice-sheet loss during past warming, and the impact of glacial meltwater on biological productivity and Sou ....Assessing the vulnerability of East Antarctica to future warming. This DECRA aims to address major gaps in our understanding of how the Antarctic Ice Sheet will respond to climate change, by enabling critical insights on its sensitivity to past climate warming. The project will apply a suite of geochemical approaches to determine – for East Antarctica’s most vulnerable basin – the extent of ice-sheet loss during past warming, and the impact of glacial meltwater on biological productivity and Southern Ocean circulation. New knowledge of how the ice sheet and ocean respond to climate warming, will lead to more reliable projections of future sea-level rise and climate. The DECRA will benefit Australia by providing a strong evidence base for policy decision-making to manage the impact of sea-level rise.Read moreRead less
