Is there a climatic tipping point for Antarctic Bottom Water formation? Antarctic Bottom Water plays an important role in global ocean circulation and climate and yet its formation is also highly sensitive to climate change. This project will analyse new seafloor, core and water samples from the understudied Cape Darnley, East Antarctica, collected on a voyage in early 2022. This new data will be used in combination with an improved high resolution regional ocean model, to understand modern and ....Is there a climatic tipping point for Antarctic Bottom Water formation? Antarctic Bottom Water plays an important role in global ocean circulation and climate and yet its formation is also highly sensitive to climate change. This project will analyse new seafloor, core and water samples from the understudied Cape Darnley, East Antarctica, collected on a voyage in early 2022. This new data will be used in combination with an improved high resolution regional ocean model, to understand modern and past Antarctic Bottom Water formation under different climate states (warmer and colder than present), to determine if there are climate tipping points for the shut down of Antarctic Bottom Water formation. The anticipated benefits include a better understanding of future climate change on this important water mass.Read moreRead less
Southern Ocean aerosols: sources, sinks and impact on cloud properties. This project aims to provide fundamental process-level understanding of atmospheric aerosol processes over the Southern Ocean, a region that has a profound influence on the Australian and global climate and where climate models perform poorly. Comprehensive observations during 3 Southern Ocean voyages and land-based measurements will enhance our knowledge of aerosols and cloud formation in that region and provide much-needed ....Southern Ocean aerosols: sources, sinks and impact on cloud properties. This project aims to provide fundamental process-level understanding of atmospheric aerosol processes over the Southern Ocean, a region that has a profound influence on the Australian and global climate and where climate models perform poorly. Comprehensive observations during 3 Southern Ocean voyages and land-based measurements will enhance our knowledge of aerosols and cloud formation in that region and provide much-needed data for improving global climate models. Expected outcomes include more accurate seasonal and latitudinal representations of Southern Ocean aerosol populations, properties and sources. The main benefit includes improvements in weather forecasting and future climate projection for Australia and the Southern Hemisphere.Read moreRead less
Profit and Loss: The commercial trade in Indigenous human remains. This project will be the first to investigate the global commercial trade in Indigenous human remains. It will employ a multi-disciplinary approach involving history, economic anthropology, economic history, and data science. The project will generate new knowledge about the 19th century global marketplace in Australian Indigenous human remains, and will reveal whether and how these are involved in the trade’s modern manifestati ....Profit and Loss: The commercial trade in Indigenous human remains. This project will be the first to investigate the global commercial trade in Indigenous human remains. It will employ a multi-disciplinary approach involving history, economic anthropology, economic history, and data science. The project will generate new knowledge about the 19th century global marketplace in Australian Indigenous human remains, and will reveal whether and how these are involved in the trade’s modern manifestations from 1950 to the present. The project will uncover an unknown history, assist repatriation practice, provide information to help reduce the modern trade, and contribute to truth-telling as a precondition of healing and reconciliation.Read moreRead less
