Summary
Unravelling the transformation pathways and fate of dissolved organic carbon and nitrogen in shallow coastal sediments. This project will significantly advance our understanding of the cycling of dissolved organic carbon and dissolved organic nitrogen in shallow coastal sediments, a potentially major part of global carbon and nitrogen cycles. This will have direct implications for the management and protection of Australian coastal systems and the world's oceans.

Summary
Dissolved organic carbon quality influences metal toxicity in freshwaters. This project aims to characterise the types of dissolved organic carbon (DOC) found within Australian freshwaters and investigate how these influence metal toxicity to organisms. DOC has the ability to decrease the toxicity of metals to organisms in natural waters, and the intensity of the decrease is related to the type of DOC. Information regarding the types of DOC commonly found within Australian waters is lacking, and ....Dissolved organic carbon quality influences metal toxicity in freshwaters. This project aims to characterise the types of dissolved organic carbon (DOC) found within Australian freshwaters and investigate how these influence metal toxicity to organisms. DOC has the ability to decrease the toxicity of metals to organisms in natural waters, and the intensity of the decrease is related to the type of DOC. Information regarding the types of DOC commonly found within Australian waters is lacking, and their impact on metal toxicity to Australian biota is unknown. This project aims to characterise DOC from different Australian ecoregions and investigate the influence of different DOCs on metal toxicity. The expected outcomes are better predictive toxicity models and better assessment of risks associated with metal contamination.Read moreRead less
Maximising carbon sequestration in freshwater wetlands. Maximising carbon sequestration in freshwater wetlands. This project aims to determine how manipulation of wetland hydrology can alter sulphur and iron cycling to inhibit methane emission and improve wetland net-carbon sequestration. Wetlands are among earth's most efficient ecosystems for carbon sequestration, but methane emission can offset this capacity. Redox cycling of sulphur and iron in wetlands can inhibit methane emission, but the ....Maximising carbon sequestration in freshwater wetlands. Maximising carbon sequestration in freshwater wetlands. This project aims to determine how manipulation of wetland hydrology can alter sulphur and iron cycling to inhibit methane emission and improve wetland net-carbon sequestration. Wetlands are among earth's most efficient ecosystems for carbon sequestration, but methane emission can offset this capacity. Redox cycling of sulphur and iron in wetlands can inhibit methane emission, but the precise biogeochemical processes and their efficiency are very poorly constrained due to a lack of studies—especially in Australian freshwater wetlands. This project is expected to inhibit methane emission in freshwater wetlands and maximise their net carbon sequestration efficiency.Read moreRead less
Dissolution of CaCO3 in sediments in an acidifying ocean. Dissolution of calcium carbonate (CaCO3) in sediments in the context of ocean acidification is poorly understood. This project will use in situ advective benthic chamber incubations and experimental manipulations under future ocean acidification scenarios to determine the controls on the dissolution of CaCO3 in sediments. This project is significant because changes in the dissolution of CaCO3 in sediments in an acidifying ocean are at lea ....Dissolution of CaCO3 in sediments in an acidifying ocean. Dissolution of calcium carbonate (CaCO3) in sediments in the context of ocean acidification is poorly understood. This project will use in situ advective benthic chamber incubations and experimental manipulations under future ocean acidification scenarios to determine the controls on the dissolution of CaCO3 in sediments. This project is significant because changes in the dissolution of CaCO3 in sediments in an acidifying ocean are at least as important, and potentially more important, than calcification to the future accretion and survival of carbonate ecosystems. It is expected that outcomes of this project will significantly advance our understanding of the drivers of the dissolution of CaCO3 in sediments and the functioning of globally important carbonate ecosystems.Read moreRead less

Summary
A high precision, automated system for studying greenhouse gas cycling in coastal environments. This facility will perform automated, long-term greenhouse gas measurements in coastal waters. The expected outcome of research at this facility is a better understanding of how the coastal ocean acts as a source or sink of carbon dioxide, nitrous oxide, methane, and volatile organic carbon.
Seagrass denitrification: importance for global nitrogen budgets. The objective of this project is to use cutting-edge techniques to measure denitrification rates in communities dominated by different tropical and temperate seagrass species. Denitrification is a globally significant critical ecosystem process, but it is poorly understood in seagrass communities. This project is significant because of the potential importance of seagrass communities for nitrogen loss via denitrification in coasta ....Seagrass denitrification: importance for global nitrogen budgets.

Denitrification is a globally significant critical ecosystem process, but it is poorly understood in seagrass communities. This project is significant because of the potential importance of seagrass communities for nitrogen loss via denitrification in coastal systems and the importance of coastal systems in the global nitrogen budget. The expected outcomes of this study may significantly advance our understanding of the functioning of coastal systems and global nitrogen budgets.Read moreRead less
Unravelling the drivers of greenhouse gas emissions in estuaries. The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling ....Unravelling the drivers of greenhouse gas emissions in estuaries. The aim of this project is to understand and quantify the factors controlling the emission of carbon dioxide, methane and nitrous oxide from estuaries. Coastal systems play a disproportionately large role in the global emissions of greenhouse gases, but this is poorly quantified. The project plans to use a combination of continuous concentration and stable isotope measurements, process measurements and advanced numerical modelling across a range of undisturbed to disturbed systems. It is intended that this project will provide information for conceptualising, calibrating and verifying models, including green-house gas production. Good models, and the data that support them, such as that provided by this study, are critical for the efficient allocation of management resources in Australian coastal systems, including by our partners. The findings from this project will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.Read moreRead less
