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

Summary
Cave microbial metabolism as a missing biogeochemical sink. The aim of this project is to unveil the microbial biodiversity, novel metabolic capabilities and chemosynthetic primary production of subsurface ecosystems, such as those found in caves. Leveraging a powerful blend of geospatial, molecular and biogeochemical approaches this project expects to identify the microbial basis of subsurface biogeochemical processes driving the earth’s major elementary cycles. Expected outcomes include a pred ....Cave microbial metabolism as a missing biogeochemical sink. The aim of this project is to unveil the microbial biodiversity, novel metabolic capabilities and chemosynthetic primary production of subsurface ecosystems, such as those found in caves. Leveraging a powerful blend of geospatial, molecular and biogeochemical approaches this project expects to identify the microbial basis of subsurface biogeochemical processes driving the earth’s major elementary cycles. Expected outcomes include a predictive framework to assess and upscale the impact of these microbial communities on the environment. Benefits include predicting and responding to climate risks, such as the desertification of agricultural soils, by uncovering how microorganisms respond to nutrient and carbon depletion.Read moreRead less

Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and p ....Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and photo-reactions of gas-phase iodide and bromide anions and their oxides. These state-of-the-art measurements of reaction kinetics and products will enable accurate chemical models that predict the impact of bromine and iodine chemistry on ozone levels and will inform future models for global climate.Read moreRead less
A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding .... A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding the critical exchanges of water and greenhouse gases (GHGs) combining field methodologies and hydrological models, under different climatic conditions. The intended outcomes will benefit management of GHG emissions, coastal flooding and vulnerable groundwater dependent habitats.Read moreRead less
Fine Tuning: A Reconciliation of Indigenous and Western Musical Traditions. Focusing on central Australian song lines, the project strengthens our knowledge, understanding and application of the intricate tuning systems that underpin traditional Indigenous musical practices. Employing a unique methodology that combines Indigenous and contemporary Western musical performance practices with cutting-edge digital technologies, the project will show how the highly nuanced and sophisticated tunings at ....Fine Tuning: A Reconciliation of Indigenous and Western Musical Traditions. Focusing on central Australian song lines, the project strengthens our knowledge, understanding and application of the intricate tuning systems that underpin traditional Indigenous musical practices. Employing a unique methodology that combines Indigenous and contemporary Western musical performance practices with cutting-edge digital technologies, the project will show how the highly nuanced and sophisticated tunings at the heart of Indigenous music-making can be preserved when transposed to contemporary Western art music contexts. In so doing, the case is made for a more genuine, equitable dialogue between Indigenous and non-Indigenous music-makers, to the mutual benefit of musicians, audiences, and society at large.
