This resource includes backscatter data for Arafura Marine Park (Arafura Sea) collected by Geoscience Australia (GA) and the Australian Institute of Marine Science during the period 2 – 15 November 2020 on the RV Solander. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with co-investment by GA and AIMS. The purpose of the project was to build baseline information for benthic habitats in Arafura Marine Park that will support ongoing environmental monitoring within the North Marine Park Network as part of the 10-year management plan (2018-2028). Data acquisition for the project included multibeam bathymetry and backscatter for two areas (Money Shoal and Pillar Bank), seabed samples and underwater imagery of benthic communities and demersal fish. This backscatter dataset contains two 32-bit geotiff files of the backscatter mosaic for two survey areas produced from the processed EM2040C Dual Head system using the CMST-GA MB Process v15.04.04.0 (x64) toolbox software co-developed by the Centre for Marine Science and Technology at Curtin University and Geoscience Australia. A detailed report on the survey is provided in: Picard, K. Stowar, M., Roberts, N., Siwabessy, J., Abdul Wahab, M.A., Galaiduk, R., Miller, K., Nichol, S. 2021.

This record provides an overview of the NESP Marine and Coastal Hub bridging study - "Support for Parks Australia’s Monitoring, Evaluation, Reporting and Improvement System for Australian Marine Parks". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The system of marine parks that spans Australia’s Commonwealth waters is among the largest in the world. These parks play a major role in conserving marine life, supporting commercial and recreational activities, and protecting cultural values significant to Aboriginal and Torres Strait Islander peoples. Parks Australia has developed management plans for five regional Australian Marine Park (AMP) networks (North, North-west, South-west, South-east and Temperate East) and the Coral Sea Marine Park (CSMP). Under each management plan, a science plan sets priorities for monitoring and research to evaluate management effectiveness and identify opportunities for improvement. This prioritisation is vital given the limited knowledge across many AMPs, the technical challenges and high costs of science in remote areas, and the finite resources available for park management. Building on foundational work from the NESP Marine Biodiversity Hub (projects SS2 and D7), this project delivered the scientific and technical advice needed to establish monitoring priorities for natural values and pressures across all AMP networks and the CSMP—completing a full national priority list for monitoring. It applied a nationally consistent four-step prioritisation framework that considered ecological importance, vulnerability to pressures, baseline data availability, and logistical feasibility. The project also updated the National Ecosystem model and Pressures & Activities datasets, conducted expert vulnerability assessments, and produced a Relative Cumulative Impact index. The combined research delivers a nationally accepted "common language" to describe natural values and pressures and a science-based method to derive monitoring priorities, aligned with the Monitoring, Evaluation, Reporting and Improvement (MERI) system—an adaptive management framework that is globally unique and a significant step towards adaptive, integrated, place-based management. Key outputs include a national database of environmental and human-use data for each management region and a refined list of monitoring priorities for each AMP Network and the CSMP. The findings highlight major knowledge gaps—particularly in the distribution of mesophotic and rariphotic reefs, intertidal ecosystems, and recreational fishing impacts—and provide guidance for improving baseline data and pressure assessments. The prioritisation framework and data products developed through this project can be re-generated over time alongside improvements in the evidence base and our understanding of how ecosystems respond to multi-sectoral activities to support continual improvement in iterative, evidence-based park management and environmental outcomes. Outputs • Digital map layers per AMP network of: (1) Ecosystems; (2) Pressures & Activities; and (3) Cumulative Benthic & Pelagic Impacts • Final Technical Report containing maps of Key Natural Values, and of spatial Monitoring Priorities, including 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 - "Conservation of spotted handfish". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Spotted Handfish (Brachionichthys hirsutus) were once common across the bays and estuaries of South-eastern Tasmania. By 1996, however, populations had declined and the species was listed as Critically Endangered under Australia’s Environment Protection and Biodiversity Conservation Act 1999. The species is relatively short-lived, (5–10 years) and matures at more than two years’ old. This leaves a short window for reproduction, which relies on egg masses laid on seafloor structures such as stalked ascidians. If spawning fails, population declines may occur rapidly. With no planktonic life stage to aid dispersal, and low adult dispersal, outside recruitment to re-establish collapsed populations is unlikely. Analysis of 23 years of Spotted Handfish survey data (1997–2019) supported by previous NESP Marine Biodiversity Hub work (Project A10) helped develop a time-series of survey data, increasing biological understanding and contributing to effective management actions. This project recommenced surveys of multiple local populations, after a two-year gap, to ensure that the potential impacts of development of the Derwent estuary and surrounds handfish populations or their habitats can be detected. Included in the population surveying was identification of suitable locations to plant Artificial Spawning Habitats (ASH) where natural spawning structures have declined. This will continue to support the species' captive breeding program with industry and foster engagement with the indigenous and broader community through participation, talks, outreach, publications, and the National Handfish Recovery Team (NHRT). Outputs • A consolidated database of all available data on spotted handfish imagery, length frequency, and GPS regions to 2022 [time-series database] • Final Project Report, including a short summary of recommendations for policy makers of key findings [written]

This record provides an overview of the NESP Marine and Coastal Hub scoping study - "Research needs for assessment and monitoring of nutrients, chemicals and antimicrobials in the marine environment". No data outputs were generated by this project. -------------------- Coastal water quality is threatened by an increasing volume of chemicals produced and used in our modern lives. These chemicals are commonly incorporated into pharmaceuticals and household items, and subsequently discharged into coastal areas from a broad range of point sources. Recently emerging contaminants include a variety of chemical (e.g. heavy metals, pharmaceuticals, pesticides, nutrients) and microbiological (e.g. pathogens, antibiotic resistant microbes) sources that are discharged in sewage, stormwater, estuarine flows and industrial wastes. For many of these chemicals, our understanding of their environmental concentrations and biological effects is limited. When new scientific information emerges to suggest that a particular contaminant may be hazardous, this is refered to as a contaminant of emerging concern (CEC). There is limited data about the environmental occurrence and biological effects of CECs, but emerging research suggests they have the capacity to be toxic. With an increasing list of CECs detected in the environment, important questions remain unanswered around which contaminants and scientific knowledge gaps should be prioritised. This desktop study engaged CEC stakeholders from academic research, government, water utilities, and non-government organisations to collaboratively identify priority CEC issues in Australia’s marine ecosystems. The project delivers a risk-based framework for future CEC research directions and water quality management priorities. Outputs • Final Project Report [written]

This resource includes seabed backscatter data for South-west Corner Marine Park collected by Geoscience Australia during the periods 9 – 12 March 2020 and 27 January – 16 February 2021 on the charter vessel Santosha. The survey was undertaken as a collaborative project with the University of Western Australia, the University of Tasmania and the Australian Centre for Field Robotics (University of Sydney) and funded through the National Environmental Science Program Marine Biodiversity Hub, with co-investment by all partners and the Director of National Parks. The purpose of the project was to build baseline information for benthic habitats on the continental shelf in the marine park that will support ongoing environmental monitoring within the South-west Marine Park Network as part of the 10-year management plan (2018-2028). Data acquisition for the project included multibeam bathymetry and backscatter for an area covering 330 km^2 offshore from Cape Naturaliste to Cape Leeuwin coast, with underwater imagery of benthic communities and demersal fish collected by University of Western Australia on separate field deployments. This backscatter dataset contains a 4 m resolution 32-bit geotiff file of the survey area produced from the processed Kongsberg EM2040C multibeam sonar system data using the CMST-GA MB Process v15.04.04.0 (.64) toolbox software co-developed by the Centre for Marine Science and Technology at Curtin University and Geoscience Australia.

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]

The data represents the results of a national model of boat-based recreational fishing effort (number of trips) around Australia. The model reflects boat-based line fishing trips in marine waters and is reported on a 5x5 nautical mile grid to a distance of 100 km from the Australian coastline. The model includes two parts: (i) allocation of fishing trips from a reporting region to individual boat ramps and (ii) allocation of fishing trips from boat ramps to adjacent marine waters. Raw fishing effort data could not be made available. Aggregated effort data is supplied as summary plots in the final report: https://www.nespmarine.edu.au/document/social-and-economic-benchmarks-australian-marine-parks
