The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Resolving the geochemistry of coastal floodplain blackwaters. Deoxygenated dead zones are a rapidly growing global crisis in coastal areas. A major cause of dead zones in our estuaries is the formation and release of blackwaters from coastal wetlands. This project will provide the knowledge necessary to manage blackwaters in these wetlands and to greatly improve the health and sustainability of our estuaries.
Functional links between estuaries and their catchments: How does land use change affect estuarine ecological and bio-geochemical function? Estuaries are iconic recreational areas of high ecological and socio-economic value. Estuarine health is strongly linked to the catchments that feed them, yet we have no detailed understanding of these links. This project will use a number of state of the art approaches to better understand how land use affects estuarine health.
Prioritising socially and economically viable land- and sea-based investments to protect coral reefs. Coral reefs are the world's most diverse marine ecosystem and are vital to hundreds of millions of people. This project will enable us to choose the best investments for coral reef conservation whether they are on the land (forest protection) or sea (marine protected areas).
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
Microbiology of a tropical creek impacted by sewage effluent: novel assessment using N-cycle functional markers and changes in community composition. Although most of Darwin Harbour has good water quality, there is much concern about local 'hot spots' where sewage has degraded ecosystem processes and values. As no bio-indicators of tropical marine water and sediment quality are known, the project will identify functional markers and microbial indicators of stress for integrated environmental mo ....Microbiology of a tropical creek impacted by sewage effluent: novel assessment using N-cycle functional markers and changes in community composition.

Managing the existing and emerging threats from coastal flow slides. This project aims to develop the first management strategies for coastal flow slides. This project expects to generate new knowledge on how flow slides are triggered, propagate inland and undermine structures. Expected outcomes include globally applicable novel models and management approaches developed by an interdisciplinary team of coastal and geotechnical engineers and coastal geomorphologist using innovative data. This is ....Managing the existing and emerging threats from coastal flow slides. This project aims to develop the first management strategies for coastal flow slides. This project expects to generate new knowledge on how flow slides are triggered, propagate inland and undermine structures. Expected outcomes include globally applicable novel models and management approaches developed by an interdisciplinary team of coastal and geotechnical engineers and coastal geomorphologist using innovative data. This is likely to provide significant benefits for planning and managing structures along coasts and bays against destructive flow slides. The project will enable the design and implementation of coastal works to protect existing structures against flow slides risks emerging with rising sea level.Read moreRead less

Metal speciation for complex studies in changing environments: The Inductively Coupled Plasma Mass Spectrometer with a High Performance Liquid Chromatography front end (HPLC-ICP-MS) for metal speciation studies is a highly valuable extension of existing cutting edge infrastructure for geochemical research. Existing invertebrate culturing capacity will also enable unique opportunities for experimental studies driven by understanding metal speciation and uptake by organisms. This facility will be housed within a highly productive research environment providing new and novel capabilities to study abiotic and biotic interactions in changing environments.Read moreRead less
New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ec ....New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ecogenomics offers a way to rapidly assess the composition of an ecological community. These techniques offer great promise, but they must be cross-validated against existing methods to derive the best ’toolbox’. Working with Melbourne Water and CSIRO the investigators aim to do this using demonstration estuaries in Victoria.Read moreRead less

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.
Unravelling the rhizosphere redox-cycling of iron, sulphur and carbon in re-flooded acidic wetlands. This project will reveal how major re-flooding will influence the cycling of iron, sulphur and carbon in re-flooded acidic, freshwater wetlands. By resolving current biogeochemical uncertainties, this project will generate the necessary knowledge platform to underpin wise long-term management of these sensitive and unique landscapes.
