Coastal permeable sediments as a novel source of greenhouse gases. Emissions of the greenhouse gases nitrous oxide and methane are increasing from unknown sources. High concentrations of these gases have been observed in coastal waters which bear the brunt of nutrient pollution (primarily nitrogen) from cities and agriculture.

High concentrations of these gases have been observed in coastal waters which bear the brunt of nutrient pollution (primarily nitrogen) from cities and agriculture. This project aims to investigate the sources of these gases within these environments and the processes that lead to their formation. This new knowledge is expected to develop new models which aim to enable us to better predict the emissions of greenhouse gases within coastal waters. Expected benefit of this will be strategies to reduce greenhouse gas emissions.Read moreRead less

This project aims to establish an environmental radioactivity research centre, equipped with ultra-low background and high-resolution alpha and gamma spectrometry systems, radon detectors and radium delayed coincidence counters. The centre will address a critical demand in Australia for precise analysis of a large suite of natural and artificial radionuclides, which will be used as tracers and chronological tools to investigate key questions in oceanography and the mining and energy, archaeological, agricultural, and forestry sectors. The facility is expected to substantially increase expertise and training in radionuclides in Australia, and promote high-level research collaborations and outputs of both national and international significance. Major outcomes of the proposed facility include better understanding of how oceans regulate climate and improved capacity to assess effects of radiation on natural ecosystems.Read moreRead less
Aerosol glassy states promote global warming, airborne toxins and pathogens. This project will improve our understanding of the role played by airborne particles in global climate, pollution and the transmission of influenza, corona virus and the common cold. It will do so by revealing the wider importance of "glassy states" of matter recently revealed in atmospheric aerosols. Glassy states are highly unpredictable quasi solids that abruptly form, interrupting the transition of a liquid to a sol ....Aerosol glassy states promote global warming, airborne toxins and pathogens. This project will improve our understanding of the role played by airborne particles in global climate, pollution and the transmission of influenza, corona virus and the common cold. It will do so by revealing the wider importance of "glassy states" of matter recently revealed in atmospheric aerosols. Glassy states are highly unpredictable quasi solids that abruptly form, interrupting the transition of a liquid to a solid. This interruption invalidates equilibrium assumptions of models of droplets as cloud nuclei and infection vectors. We will develop and validate a numerical tool for predicting glassy state formation and its impact in broad classes of aerosol that include particles critical to cloud formation and infection transmission.Read moreRead less

This project aims to integrate elemental stoichiometry, bio-elemental imaging and metabolomics to develop a common ‘elemental currency’ as an entirely new diagnostic of coral fitness.

This project aims to integrate elemental stoichiometry, bio-elemental imaging and metabolomics to develop a common ‘elemental currency’ as an entirely new diagnostic of coral fitness. Coral reefs generate invaluable ecosystem services, but are on the verge of global collapse. Efforts to resolve coral traits that promote ecological resilience have been unable to integrate biological and environmental complexities of reef systems into a unifying diagnostic of reef health. Natural extremes will provide the platform to identify key metabolic traits vital for future survival, to establish adaptive elemental signatures that can scale from organism to ecosystem. The project is expected to enhance capacity of marine managers and reef stakeholders to effectively manage and safeguard Australia’s reefs and the cultural and ecosystems.Read moreRead less
The forgotten role of the ground state in atmospheric photochemistry. This project aims to provide novel solutions to two deficiencies in current atmospheric chemistry models. That is, molecular hydrogen (H2) is underestimated by up to a factor of two, and in polluted areas, HO2 concentrations are underestimated by up to a factor of ten. The project will investigate these solutions and assess their local and global atmospheric impact.

This project aims to provide novel solutions to two deficiencies in current atmospheric chemistry models. That is, molecular hydrogen (H2) is underestimated by up to a factor of two, and in polluted areas, HO2 concentrations are underestimated by up to a factor of ten. The project will investigate these solutions and assess their local and global atmospheric impact. By better characterising the atmospheric H2 budget, and the role of ground state reactions in general, the predictive ability of atmospheric models will be improved. This will allow, for example, the outcomes of any change in atmospheric H2 concentration, potentially as part of any future hydrogen economy, to be predicted before they occur. The benefits of this project are global: they allow us to better predict the impact of changes to atmospheric composition – before they occur, and local: Australia’s strengths in physical, theoretical and atmospheric chemistry are reinforced.Read moreRead less
