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
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. This frontier project made possib ....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. This frontier project made possible by samples collected using Remote Operated Vehicle (ROV) technology rarely available in Australia, will also help to understand how SO circulation has influenced past changes in global climate and its future role in controlling ocean productivity in a warming world with rapidly increasing atmospheric carbon dioxide.

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.
Holding coral reefs together with soluble cement. This project aims to characterise and understand cement formation in coral reefs. Coral reefs are constructed by cementing together aragonite building blocks made by corals. The main cementing agent is high-magnesium calcite, the most soluble carbonate mineral and susceptible to ocean acidification. High-magnesium calcite cements are best developed on the high energy margins of coral reefs. This project will quantify how crustose coralline algae ....Holding coral reefs together with soluble cement. This project aims to characterise and understand cement formation in coral reefs. Coral reefs are constructed by cementing together aragonite building blocks made by corals. The main cementing agent is high-magnesium calcite, the most soluble carbonate mineral and susceptible to ocean acidification. High-magnesium calcite cements are best developed on the high energy margins of coral reefs. This project will quantify how crustose coralline algae produces high-magnesium calcite and controls the dissolution and reprecipitation of high-magnesium cements. This project intends to quantify rates of reef cementation, susceptibility to ocean acidification and warming, and possible mitigating effects of alkalinity addition.Read moreRead less
Unravelling the history of nitrogen cycling within the central Great Barrier Reef. This project aims to use coral skeleton geochemical analysis to establish if, when, and how nitrogen cycling changed along the central inshore region of the Great Barrier Reef (GBR) lagoon. Increasing anthropogenic nitrogen discharge to coastal waters could drive ecosystem decline in the GBR, one of Australia’s most sensitive and economically valuable natural environments. However, the full effect of anthropogenic ....Unravelling the history of nitrogen cycling within the central Great Barrier Reef. This project aims to use coral skeleton geochemical analysis to establish if, when, and how nitrogen cycling changed along the central inshore region of the Great Barrier Reef (GBR) lagoon. Increasing anthropogenic nitrogen discharge to coastal waters could drive ecosystem decline in the GBR, one of Australia’s most sensitive and economically valuable natural environments. However, the full effect of anthropogenic nitrogen is unclear due to a lack of long, continuous records. This project will unravel the history of nitrogen cycling in the GBR since the mid-1800s, knowledge crucial for managing this reef system.Read moreRead less

Summary
The mangrove carbon pump: Resolving the contribution of underground respiration to mangrove greenhouse gas and carbon budgets. Mangroves are considered an important global carbon sink. However, there is an imbalance of about 50 per cent in mangrove carbon budgets. This project will resolve whether advective pore water exchange and associated underground respiration represents the missing component of mangrove carbon and greenhouse gas budgets. This innovative project will examine the previously ....The mangrove carbon pump: Resolving the contribution of underground respiration to mangrove greenhouse gas and carbon budgets. Mangroves are considered an important global carbon sink. However, there is an imbalance of about 50 per cent in mangrove carbon budgets. This project will resolve whether advective pore water exchange and associated underground respiration represents the missing component of mangrove carbon and greenhouse gas budgets. This innovative project will examine the previously overlooked concept that crab burrow flushing is a major driver of biogeochemical reactions in mangroves. It will use a combination of new experimental and modelling approaches and will contribute to closing a significant gap in our understanding of the coastal carbon cycle.Read moreRead less
Unravelling the legacy of groundwater pollution to coastal waters. This project aims to resolve whether groundwater polluted decades ago is now seeping out along shorelines, and driving coastal water quality. The project will challenge common assumptions about the sources of chemical pollution to Australian coastal waters using a combination of cutting-edge analytical techniques, modelling, and laboratory investigations. The outcomes of the project will support the development of pollutant budge ....Unravelling the legacy of groundwater pollution to coastal waters. This project aims to resolve whether groundwater polluted decades ago is now seeping out along shorelines, and driving coastal water quality. The project will challenge common assumptions about the sources of chemical pollution to Australian coastal waters using a combination of cutting-edge analytical techniques, modelling, and laboratory investigations. The outcomes of the project will support the development of pollutant budgets and models required for the effective creation of water management solutions. As a result, the project will benefit the management of iconic waterways experiencing persistent, unresolved water quality issues which are costing the government billions of dollars.Read moreRead less
