Research outcomes from this new facility will empower government bodies, resource industries, and indigenous stakeholders with key baseline information to ensure the sustainable and sensitive development of west Australia's unique coastal and offshore regions, across heavily populated and pristine environments. This includes projecting future impacts on local industries (eg. energy, fisheries, tourism), rising shorelines with critical implications for existing and developing communities, and enhancing the resilience of habitats at risk. These are crucial to mitigate the impacts from environmental change that could severely affect our regional and national economies, as well as the style and quality of life of current and future generations.Read moreRead less

This project aims to quantify the respiratory pathways and the importance of hydrogen as an intermediate during anoxia in permeable (sand) sediments which dominate our coastline. It is anticipated the findings of this project will enable more accurate fundamental understanding of sediment diagenetic processes which control nutrient regeneration and loss pathways in the marine environment. This will enable better management of these environments in the face of increasing coastal population growth.Read moreRead less
Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critica ....Ocean Acidification in a Rapidly Increasing CO2 World. Carbon dioxide not only acts as a greenhouse gas but is being dissolved at increasing rates into the surface waters of the world's oceans, causing ocean acidity. We will examine how the rapidly increasing trend towards acidity in the oceans surrounding Australia is effecting the ability of marine organisms to calcify and determine the rate at which the world's ocean sink for CO2 is being reduced. New constraints will be placed on the critical threshold limits of CO2 emissions for sustainable calcification in both shallow tropical and deep-water marine ecosystems of the Southern Oceans.Read moreRead less
Deep-sea coral records of Southern Ocean climate and nutrient dynamics . Deep-sea coral and seawater nutrient profiles collected from the Southern Ocean (SO) facing submarine canyons of south-west Australia will be used to provide new insights into the role of the SO overturning circulation in modulating global climate as well as supplying the essential nutrients that make these canyons biodiversity hot-spots for seasonal aggregations of killer and blue whales.

Summary
An Equilibrium Inlet-Proton Transfer Reaction-Mass Spectrometer. Biogenic volatile organic compounds (BVOC) play a key role in earth system processes but little is known about the amount of BVOCs emitted, and the mechanisms underlying their production in marine habitats, despite these being potential hotspots for BVOC emissions. The aim of this proposal is to custom build a portable equilibrator inlet proton transfer reaction mass spectrometer for measurements of BVOC’s in coastal waters. This w ....An Equilibrium Inlet-Proton Transfer Reaction-Mass Spectrometer. Biogenic volatile organic compounds (BVOC) play a key role in earth system processes but little is known about the amount of BVOCs emitted, and the mechanisms underlying their production in marine habitats, despite these being potential hotspots for BVOC emissions. The aim of this proposal is to custom build a portable equilibrator inlet proton transfer reaction mass spectrometer for measurements of BVOC’s in coastal waters. This will be the first such instrument in the southern hemisphere and it will enable us to make in situ, high-precision measurements which will lead to ground-breaking advances that will revolutionise our understanding of BVOC cycling in coastal environments and their influence on the global climate system.

Probing the response of Southern Ocean phytoplankton to changes in iron biogeochemistry, light and pH associated with climate change. Determining factors that influence the health and vitality of coastal and open-ocean regions is crucial to maintaining marine biodiversity and the Earth’s climatic balance. This research project will determine the role climate change and ocean acidification will have on the ability of Southern Ocean phytoplankton to flourish.
Resolving dissolved organic matter: new multi-dimensional separation approaches. To fully understand and model global carbon cycles the source, nature and fate of oceanic dissolved organic carbon is an essential element. This project will develop, model and apply new orthogonol and complementary separation science based technologies to further the comprehensive characterisation and understanding of these complex systems.
A changing climate for calcification on the Great Barrier Reef: past, present and future. The Great Barrier Reef (GBR) is a national and international icon, recognised through its inscription as a World Heritage Area and economic and social value to Australians. Maintenance of the GBR as we know it is now compromised by a rapidly changing climate. Ocean acidification, warming water temperatures and increased freshwater will progressively be detrimental to the fundamental reef-building process ....A changing climate for calcification on the Great Barrier Reef: past, present and future. The Great Barrier Reef (GBR) is a national and international icon, recognised through its inscription as a World Heritage Area and economic and social value to Australians. Maintenance of the GBR as we know it is now compromised by a rapidly changing climate. Ocean acidification, warming water temperatures and increased freshwater will progressively be detrimental to the fundamental reef-building process of calcification. Informed policy and management strategies in a rapidly changing physical environment require determination, for short and long time frames, of the regional consequences and impacts of changing reef-building capacity.Read moreRead less
Are subterranean estuaries a source or sink of greenhouse gases? The aim of this project is to investigate the role of subterranean estuaries and submarine groundwater discharge on the marine cycle of the greenhouse gases carbon dioxide, methane, and nitrous oxide. The expected outcome of this project is a better understanding of the role of coastal environments as a net source or sink of greenhouse gases.
