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
Australian dust: its response to, and role in, climate change. Atmospheric dust plumes can affect global climate, but the impact of Australian dust on climate is poorly known even though it is a major dust source. This project will study the magnetism of dust deposits in marine sediments to understand how Australian dust influences climate in order to better predict the influence of humans on future climate.

Summary
Resolving nutrient groundwater exports versus soil burial in mangroves. This project aims to examine the role of mangroves in the sequestration and burial of nutrients. Coastal areas increasingly receive enriched nutrient loads, driving anthropogenic eutrophication. Mangrove wetlands naturally filter and bury large quantities of nutrients through soil accretion. This project aims to quantify nutrient groundwater export as related to mangrove soil nutrient retention and determine if these wetland ....Resolving nutrient groundwater exports versus soil burial in mangroves. This project aims to examine the role of mangroves in the sequestration and burial of nutrients. Coastal areas increasingly receive enriched nutrient loads, driving anthropogenic eutrophication. Mangrove wetlands naturally filter and bury large quantities of nutrients through soil accretion. This project aims to quantify nutrient groundwater export as related to mangrove soil nutrient retention and determine if these wetlands have the potential to provide negative feedback to coastal eutrophication. The project plans to use state-of-the-art radionuclide tracer technology to quantify the relationship between groundwater discharge and historical soil nutrient retention.Read moreRead less
