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
Sea level change and climate sensitivity. This project will aim to improve understanding of climate and sea-level change on timescales relevant to longer-term planning, by characterising the relationship between past sea-level/ice-volume change and other key climate factors such as temperature and greenhouse gases, and by quantifying how rapidly sea level may adjust to climate change.
Driving a palaeomagnetic revolution: geophysical and environmental signals from magnetic biominerals. Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive geological occurrence. This project proposes to determine: the mechanisms by which ....Driving a palaeomagnetic revolution: geophysical and environmental signals from magnetic biominerals. Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive geological occurrence. This project proposes to determine: the mechanisms by which magnetofossils contribute to sedimentary palaeomagnetic signals; if magnetofossil occurrences provide information about the marine carbon cycle; and, if magnetofossil chemistry can constrain the depth of sedimentary palaeomagnetic signal acquisition. These are major outstanding questions in sedimentary palaeomagnetism.Read moreRead less

Australian membership of the International Ocean Discovery Program:
This project is for a 5-year membership of the International Ocean Discovery Program, the world’s largest collaborative research program in earth and ocean sciences addressing international priorities. The program conducts seagoing coring expeditions and monitoring of instrumented boreholes to study the history and current activity of the Earth, recorded in sediments and rocks below the seafloor. The program’s aims include understanding past global environments on multiple time scales, the deep biosphere, plate tectonics, occurrence and distribution of resources, and generation of hazards. Several multinational expeditions are scheduled and planned in our marine jurisdiction and within the Australasian region. Read moreRead less
Pre-industrial sea-surface temperatures in the Australian region. Humanity faces an enormous challenge as there is much debate on whether the world is warming up and when this started. This project will document sea-surface temperature records over the last millennium for the Australian region and provide data of critical importance to global climatology and oceanography that precede the instrumental record.
El Niño in a changing climate: novel long-term perspectives from Pacific corals and model simulations. El Niño and La Niña events have a profound influence on Australian drought conditions and rainfall. Forecasting is hampered by short climate records, which do not capture the full range of El Niño dynamics. This project aims to generate records of unprecedented length and spatial coverage from key sites across the western and central equatorial Pacific. Five hundred years of continuous, monthly ....El Niño in a changing climate: novel long-term perspectives from Pacific corals and model simulations. El Niño and La Niña events have a profound influence on Australian drought conditions and rainfall. Forecasting is hampered by short climate records, which do not capture the full range of El Niño dynamics. This project aims to generate records of unprecedented length and spatial coverage from key sites across the western and central equatorial Pacific. Five hundred years of continuous, monthly-resolution climate data will be integrated with output from state-of-the-art climate model simulations to distil the key processes that cause El Niño to vary. This project aims to provide major advances in determining the full range of El Niño and La Niña behaviour, leading to improved forecasts of future changes, with consequences for Australia's water security.Read moreRead less
Deep Atlantic’s role in millennial atmospheric carbon dioxide changes. This project aims to fill in a critical knowledge gap in global carbon cycle research, by generating the first high-resolution deep Atlantic carbonate ion and nutrient records for the last 150,000 years. The project will derive air-sea carbon dioxide (CO2) exchange signals, which permit straightforward evaluation of the deep Atlantic’s role in millennial atmospheric CO2 changes under various climate conditions. The intended o ....Deep Atlantic’s role in millennial atmospheric carbon dioxide changes.

The project will derive air-sea carbon dioxide (CO2) exchange signals, which permit straightforward evaluation of the deep Atlantic’s role in millennial atmospheric CO2 changes under various climate conditions. The intended outcome of this project is to substantially improve our understanding of the mechanisms that govern the global carbon cycle. This should provide significant benefits including the assessment of models used to predict future global warming due to anthropogenic CO2.Read moreRead less
Mid-depth Atlantic circulation during the Last Glacial Maximum and deglaciation. The history of ocean circulation at the intermediate water depth remains controversial, limiting our understanding of the interplay of ocean circulation, climate changes, and the global carbon cycle.

The history of ocean circulation at the intermediate water depth remains controversial, limiting our understanding of the interplay of ocean circulation, climate changes, and the global carbon cycle. This project aims to generate trace elemental and isotopic records for 10 key locations in the Atlantic Ocean, which constrain physicochemical properties of water masses at unprecedented temporal resolution during the last glacial maximum and the subsequent deglaciation. This multi-proxy approach will reconcile controversy and pin down the evolution of mid-depth Atlantic circulation in the past, and thereby substantially improve our understanding of the climate system.Read moreRead less

Summary
A world-class rock magnetic facility to support Australian palaeomagnetic and environmental research. Magnetic properties of rocks and environmental particles provide information about a vast range of geological and environmental processes. We propose to develop a facility that will enable detection and interpretation of these magnetic signals to aid understanding of climate change, mineral exploration, and the geological development of Australia.
