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.
