  • This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "Microplastics in South Eastern Australian coastal waters: synthesising current data and identifying key knowledge gaps for the management of plastic pollution". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Plastic pollution is pervasive in coastal environments globally and in Australia. Due to their small size, microplastics (pieces <5mm) are readily ingested by marine organisms and potentially accumulate across food webs, raising concerns for biota, ecosystem services and human health. Yet, to define guidelines and support policy actions that curb microplastic pollution, managers and decision-makers lack clear, synthesised information on this multifaceted issue, including on occurrence, sources, and pathways of microplastics in coastal and marine environments. This project produces a synthesis of current data on microplastics in South Eastern Australian coastal waters (i.e. South Australia, Victoria and New South Wales) and identify key knowledge gaps for the management of plastic pollution. Planned Outputs • List of compiled datasets relating to microplastics in SE Aus waters [spatial dataset] • Scoping document synthesising the information available on the presence of microplastics in coastal marine environments in South Eastern Australia, its potential sources and pathways [written]

  • The movement and behaviour of the Southern Rock Lobster (Jasus edwardsii) was monitored using a radio acoustic telemetry systems at two sites in eastern Tasmania.

  • NESP Marine Biodiversity Hub Project C2 involved integration and analysis of three existing monitoring datasets: the Reef Life Survey (RLS), IMAS Long-term MPA (LTMPA), and AIMS Long-term (AIMS LTM) monitoring programs. These analyses involved generating new derived data on indicator values for survey sites in each of the datasets, which have been reported in the 2016 State of the Environment (SoE) report. Indicators included the biomass of large fishes, the community temperature index, the proportion of invasive species, crown-of-thorns seastar density and the proportion of threatened species. Details of calculation of these indicators and summary of trends in values across sites and times are provided in detail in a manuscript currently in the review process for an international journal [RSS to provide publication details once available], as well as in metadata supplied for the State of the Environment report. This metadata record provides links to each of the three datasets used in the synthesis, and links to access the derived biological indicator data reported in the 2016 SoE report. See "On-Line Resources" section.

    Investigations of the impact of sewage and heavy metal inputs on inshore rocky reef communities have been limited to date because the scale of information on levels of pollutants has been much broader than the span of transects at sites investigated. As a consequence, analyses have been confounded by poor information on the variety of stressors operating at any site. Finer resolution data on pollutants are needed. To address this deficiency, the influence of sewage, heavy metals and other pollutants were assessed by collecting sediment samples at Reef Life Survey ecological monitoring sites and measuring a range of associated markers. This includes basic biogeochemical information (pH, turbidity, total phosphate, TKN, total organic carbon), stable isotopes (delta15N, delta13C), heavy metal concentrations, hydrocarbon concentrations.

    Marine benthic habitat data for Tasmanian coastal waters from the LWM (Low water mark) to 40 metres in depth or 1.5 kms from shore. A full breakdown of habitat classifications is available on the SeaMap Tasmania website: http://seamap.imas.utas.edu.au/habitats/

  • Collected benthic community structure (species and abundance) and physical/chemical attributes (including sediment grain size, redox, sulphide and depth) for a large number of locations in the Huon and Derwent estuaries of south east Tasmania. Data was collected using van veen grab, divers where necessary or core samples. All locations include heavy metal data and site information. Most data was collected with spatial references (GPS).

    Temperature loggers have been deployed at a range of sites statewide in waters ranging between 6 and 22m depth. From 2012, 27 sites around Tasmania are being monitored. This record shows data collected from 2004 up to December 2020. Data is still being collected (June 2021) and will be added to this collection as it becomes available.

  • This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "Towards a consolidated and open-science framework for restoration monitoring". No data outputs are planned for this project. -------------------- Coastal habitat restoration is scaling up rapidly in Australia and covers a range of habitats including oyster reefs, seagrass meadows, mangrove forests, kelp forests, and saltmarshes. Every restoration project includes some attempt at monitoring outcomes but currently these are piecemeal, uncoordinated, often poorly funded, and rarely follow Open Science protocols. Previous NESP-funded projects have improved understanding of the ecology and service provision of threatened ecosystems and established targets for repair based on reference conditions (e.g. Marine Biodiversity project B4). They have also established an extensive database of marine and coastal restoration projects (ARCN: project E5), and have supported the development of monitoring, evaluation, reporting and improvement systems (MERI) for various sectors or projects. By combining the knowledge of all Australian researchers undertaking monitoring of restoration projects, across multiple habitats, this project will build upon these previous projects to synthesise the approaches for monitoring of habitat restoration. It will also explore integration of new technologies, such as automation, artificial intelligence, and eDNA, within the monitoring framework to improve efficiency and cost-effectiveness. The primary output will be a co-ordinated and open-science framework for restoration monitoring across projects, scales and habitats, that integrates clearly articulated hypotheses to determine the goals for restoration. This framework will streamline development of future restoration projects and ensure that maximum value from monitoring activities is achieved. Planned Outputs • Literature review [written] • Guidelines document (best-practice toolkit) [written] ---no data outputs are planned for this project---

  • We undertook a review of peer-reviewed publications focusing on coastal and marine microplastics relevant to South Eastern Australia (South Australia, Victoria, and New South Wales), as well as from ongoing citizen science programmes from AUSMAP. Here we summarise the location of the studies on microplastics, if the study focused on water, sediment or biota, and the DOI of the publication.
