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
Unravelling the cycling of nitrogen along a subtropical freshwater-marine continuum using a multi-isotope, multi-tracer and modelling approach. This project will significantly advance our understanding of the sources, cycling and pathways of nitrogen along a sub-tropical catchment-river-estuary. As such, the findings from this research will have direct implications to the management, rehabilitation and protection of waterways (including biodiversity) in Australia.
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

Laser ablation multiple split streaming: This geochemical facility with an innovative, world-leading micro-analytical capability intends to support research of fundamental and strategic problems at the frontiers of the Earth and Environmental Sciences. The facility aims to allow new insight into the age, composition, thermal history and structure of the Australian continent, as necessary for delineating mineral endowment and for tracing the sources of ore metals. It will provide a higher resolution record of climate and environmental change which will better inform assessment of the impacts, both locally and regionally. It is intended that the facility will amplify national and international scientific collaboration and create unique research opportunities for Australian-based scientists.Read moreRead less
The importance of sediment denitrification in the nitrogen budget of the inshore wet tropics section of the Great Barrier Reef Lagoon. The Great Barrier Reef (GBR) is a World Heritage Area that has significant ecological, economical and social values for the Australian (world) community. Nutrient over-enrichment (eutrophication) associated with runoff from adjacent catchments is a major threat to the GBR. This study will quantify what proportion of the terrestrial nitrogen load delivered to the ....The importance of sediment denitrification in the nitrogen budget of the inshore wet tropics section of the Great Barrier Reef Lagoon. The Great Barrier Reef (GBR) is a World Heritage Area that has significant ecological, economical and social values for the Australian (world) community. Nutrient over-enrichment (eutrophication) associated with runoff from adjacent catchments is a major threat to the GBR. This study will quantify what proportion of the terrestrial nitrogen load delivered to the inshore wet tropics section of the Great Barrier Reef Lagoon is removed through sediment denitrification. Critical information for understanding the process of eutrophication in the GBR Lagoon that will be used by our Industry Partner in the management, rehabilitation and protection of the GBR.Read moreRead less

A coupled high temperature elemental analyser - gas chromatograph - mass spectrometer for climate, water and ecological research: This project is for a high temperature, elemental analysis, gas chromatography, isotope mass spectrometry facility. This would permit the analysis of the isotopes of up to four elements in a range of environmental samples such as tree cellulose, ecological samples and dissolved nutrients in surface and ground waters. Results will help improve our understanding of climate - surface water - ground water interactions, ecosystem function, and past climate and environmental change. The new facility will meet the need for organic isotope analyses to better understand the underlying physical processes.Read moreRead less
