  • The principle aim of this project was to map the fine-scale spatial distribution of key abalone habitat impacted by urchins in < 25 m water depth using multibeam acoustic imagery. Detailed substrate type (Pavement Reef, Megaclast Reef, Mixed Consolidated Sediment/Reef and Sand), and kelp coverage maps have been produced for the east coast of Tasmania. Large urchin barrens have been predicted and the minimum quantifiable unit of which small incipient barrens can be detected has been identified using this acoustic water column technique. This data provides a snapshot of the 2021 distribution of seafloor habitats and associated vegetation distribution, and will assist in the facilitation of strategic decision making for urchin control and abalone management. Data for download has been split by fishing block (22-24, 27-30). This record describes *FISHING BLOCK 23*. The following data products are available for download, for each fishing block: • 50cm resolution bathymetry • 50cm resolution substrate type (Seamap Australia classification) • bathymetry derivatives (seabed slope, curvature, rugosity, 1 and 2m contours) • water column data - 1m mean signal • water column data - 9m2 raw block statistic • water column data - vegetation likelihood classification See associated records for access to data from other fishing blocks (22, 24, 27, 28, 29, 30).

  • This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "Australia’s Coastal Shorebirds: Trends and Prospects". No data outputs were generated by this project. -------------------- Coastal Australia is home to 37 regularly occurring migratory shorebird species, with many protected areas including Ramsar sites designated on the basis of shorebird populations. Many migratory shorebirds are declining rapidly, and hence the focus of conservation efforts at multiple levels of government in Australia and overseas. However, trend data are now nearly 10 years old, meaning the information available to assess where conservation actions are needed most urgently and whether conservation efforts are helping species recover are outdated. To ensure populations have the best chance at recovery and that resources are allocated where they are most likely to have the greatest positive impacts, it is critical to maintain up-to-date information on species trends. This project analyses 30 years of shorebird monitoring data collected by citizen science groups across Australia and curated by BirdLife Australia’s National Shorebird Monitoring Program.to update national trend estimates, while also assessing the relative effects of human pressure and conservation efforts on population trends. This project will set the stage for building the next decade of coastal shorebird conservation activity in Australia, coordinated through the national mechanism of the End User: National Migratory Shorebird Conservation Action Plan Steering Committee, with representatives from national and state governments as well as leading shorebird experts. Outputs • Final technical report with analysed data and a short summary of recommendations for policy makers of key findings [written] ---no data outputs were generated by this project---

  • This record provides an overview of the NESP Marine and Coastal Hub scoping study - "Research needs for a national approach to socio-economic values of the marine environment". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Effective management of the marine estate requires recognition of the fact that we live in a connected human-natural system. Human uses of the marine environment often create pressures that drive overall condition, but it is also these uses that create ‘benefits’ or ‘values’ in the marine environment. Thus understanding the coupled relationships between humans and nature is essential to managing the marine environment that delivers environmental, social and economic outcomes. In this project we will work with stakeholders (particularly DAWE) through co-design to identify: (a) social and economic research priorities, and (b) existing social and economic data sets to address these priorities. This project includes, as a key differentiation from previous NESP MHB projects, an additional theme on implementation and behaviour change that will ensure research can inform the full pathway from policy to on ground action. This work will set the research direction for projects under the NESP 2 MAC and involve co-designed project proposals. Outputs • Inventory of compiled datasets relating to relevant economic values, threats, and socioeconomic values for Case Study locations [grey data] • Final technical report with analysed data and a short summary of recommendations for policy makers of key findings [written]

  • 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---

  • This record provides an overview of the NESP Marine and Coastal Hub bridging study - "Characterising values and identifying indicators and metrics of fish and benthic assemblages within the Capes region of the South-west Corner Marine Park". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Inventory surveys of Australian Marine Parks (AMPs) provide a broad description of the natural assets that exist in Commonwealth waters. These data can be further explored to identify biological indicators and metrics to cost-effectively monitor the AMPs and inform the AMP Monitoring Evaluation Reporting and Improvement (MERI) system. This project will use fish and seafloor imagery obtained from the recent inventory survey in the Capes region of the South-west Corner Marine Park to identify important natural values and indicators of fish and benthic assemblages relevant to park management and the AMP MERI system. Outputs • Habitat annotations to (1) AUV and (2) drop camera imagery following nationally agreed protocols (extended CATAMI classification - the Australian morphospecies catalogue) - to be published through the Understanding Marine Imagery (UMI) IMOS sub-facility • Bathymetry from National Park and Special Protection zones - published on AusSeabed • Geomorphic features map for existing fine scale bathymetry coverage of the National Park and Special Protection zones • Habitat map for existing fine scale bathymetry coverage (validated from from drop camera surveys for National Park and Special Protection zones • Fish and shark annotations of stereo-BRUVs • Science communication article for the Australian Marine Parks Science Atlas [written]

  • This record provides an overview of the NESP Marine and Coastal Hub scoping study - "Identify knowledge gaps and solutions for extent mapping of Australian marine and coastal wetlands". No data outputs were created by this project. -------------------- Marine and coastal wetlands provide extensive ecosystem services to Australia, and a comprehensive inventory is required for effective conservation and protection. This project will identify key knowledge and inventory gaps and determine solutions to progress a consolidated inventory within the context of a wider review of national mapping capacity for wetlands. Gaps and solutions will be identified through targeted surveys and workshops with end-users and researchers following a review of relevant data and literature. A summary of the status of mapping habitat attributes and services such as blue carbon, coastal protection and shorebird habitat will be produced. The outcome will be identified prioritisation for future investment to fill knowledge gaps. Outputs • Report reviewing and synthesising knowledge gaps in inventory mapping of marine and coastal wetlands, identifying effective solutions, and guiding subsequent research projects for enhancing wetland mapping [written] ---No data outputs were created by this project.---

    These data are from a voyage (IN2019_V01) on RV Investigator with the Australian Antarctic Division (AAD), that took place during January-March 2019. The Chief Scientist was Mike Double from the AAD. Clara R. Vives collected biogeochemical data on the voyage, and performed a series of incubation experiments for her PhD. The purpose of the study was to investigate the effects of iron and light on phytoplankton growth off East Antarcitca. Data include CTD nutrients, chlorophyll and oxygen as well as underway phytoplankton physiology (measured as the photochemical efficiency) and pCO2. Some data are duplicated but not in exactly the same format on the CSIRO Data Trawler.

  • Total organic carbon (TOC) sediment stocks as a CO2 mitigation service require exclusion of allochthonous black (BC) and particulate inorganic carbon corrected for water–atmospheric equilibrium (PICeq). For the first time, we address this bias for a temperate salt marsh and a coastal tropical seagrass in BC hotspots that represent two different blue carbon ecosystems of Malaysia and Australia. Seagrass TOC stocks were similar to the salt marshes with soil depths < 1 m (59.3 ± 11.3 and 74.9 ± 18.9 MgC ha-1, CI 95% respectively). Both ecosystems showed larger BC constraints than their pristine counterparts did. However, the seagrass meadows’ mitigation services were largely constrained by both higher BC/TOC and PICeq/TOC fractions (38.0% ± 6.6% and 43.4% ± 5.9%, CI 95%) and salt marshes around a third (22% ± 10.2% and 6.0% ± 3.1% CI 95%). The results provide useful data from underrepresented regions, and, reiterates the need to consider both BC and PIC for more reliable blue carbon mitigation assessments.

  • 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. 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]
