This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "A photo-identification study of southern right whales to update aggregation area classification in the southwest of Australia". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The population of Southern Right Whales (SRW) in the Southern Hemisphere has been recovering slowly from near extinction due to its decimation from whaling before its ban in the mid-1970’s. The population that visits the Australian coast each year to breed is estimated to have increased by about 4–5% per year in the past two decades, bringing the total population to approximately 3,500 whales. As the population increases, the whales extend their breeding areas into previously occupied suitable habitat. As the species recovers, there is increasing evidence of expansion of aggregation areas. Consequently, there is a need to update known established aggregation areas and Biologically Important Areas (BIAs) and update relevant Marine Parks management plans based on new evidence. Flinders Bay and Geographe Bay off south-western Western Australia were likely to have been important calving areas before commercial whaling began. Much of this habitat is popular for recreational boating and other marine activities. This project collated and completed photo-ID matching of southern right whale images collected between 2010 to 2020 in the southwest of Australia, and uploaded these to the Australasian Right Whale Photo-Identification Catalogue (ARWPIC). The photo-ID matching outcomes provide evidence that Flinders Bay and Geographe Bay now fit the criteria to be recognised nationally as Biologically Important Areas (BIAs) for Southern Right Whales. Outputs • Photo-identifications of individual whales in southwestern Australia for 1991-2021 (photo-matches contributed to ARWPIC) • Final Project Report, including evidence and recommendations for updating aggregation area classification in the southwest of Australia according to the Commonwealth criteria [written]

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project C1 - "Improving our understanding of pressures on the marine environment". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The marine environment in Australia is influenced by a wide range of different pressures that impact on different parts of the marine ecosystem in different ways. This project aims to assist DoE, and other research users, to improve understanding of the potential impacts of anthropogenic disturbance to marine conservation values by providing up-to-date data and analyses on the spatial distribution of pressures and trends. The research is designed to inform decision making under the EPBC Act (acceptability of proposed activities, evaluation of effectiveness of mitigation measures) on NMES (including Key Ecological Features), implementation of multiple strategies in four Marine Bioregional Plans (i.e. strategies B, C, D and F), management of Commonwealth Marine Reserves (e.g. strategies 1 and 2 in the South-east Commonwealth Marine Reserve Network Management Plan 2013-23) and State of the Environment reporting. The project will involve a re-examination of the pressure analyses undertaken through the marine bioregional planning program and the 2011 SOE Report (marine chapter) and determine where pressure mapping can be improved to enhance those analyses (for instance for those pressures for which data deficiency was identified). It will also examine the strengths and weaknesses of the different pressure assessment methodologies used by both the MBP process and the SOE 2011 process and propose a methodology that can support both initiatives into the future. The project will provide pressures profiles for CMRs and will assist Parks Australia in understanding how pressures interact with the values they identify in CMRs. The project will also consider relative impact, and how spatial mapping can assist in understanding both relative and cumulative impact. As an adjunct to the cumulative impact investigation, the project will also investigate how changes in socio-economic valuing of conservation values may influence the degree of investment in understanding and management of cumulative impact. This particular work will further the risk-based approach to cumulative impact that was investigated under the NERP Hub. Planned Outputs • Produce description of summary of changes and trends in pressures on the commonwealth marine environment in the offshore marine environment from 1991 to 2010. • Production of inshore and offshore pressure summaries to inform SOE reporting (2011-2015) • Produce description of trends in pressures acting on the commonwealth marine environment (onshore & offshore) between 1991 & 2015, with refined summaries for all KEFs and CMRs. • Distribute pressure data and pressure data summaries through NPEI compliant data infrastructure. • Produce analysis and description of the likely future states (for example, climate (interannual and decadal), shipping, modification of fisheries activity, coastal eutrophication) • Re-evaluation of the pressure assessments published in the 2012 Marine Bioregional Plans , ensuring consistency of output, updating the profiles for all KEFs • Report on the changing socio-economic valuing of conservation values to the concept of acceptable impact, or acceptable risk of impact • Report on a risk based framework to manage the uncertainty information bases for different decision making requirements with example case

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A5 - "Defining connectivity of Australia’s hammerhead sharks". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Hammerhead sharks are the focus of conservation management through recent listing on Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and Convention on the Conservation of Migratory Species (CMS). The clear data gap for Department of the Environment and Energy (DoEE) and Great Barrier Reef Marine Park Authority (GBRMPA) is connectivity of populations across national and international jurisdictions. This project applies genetic and satellite telemetry to examine the movement and connectivity of hammerhead sharks. This will help determine use of Australian Marine Parks (AMPs) and the Great Barrier Reef Marine Park (GBRMP), and define Biologically Important Areas (BIAs) where possible. These data will be assimilated with current research to provide a more comprehensive understanding of the status of hammerhead shark populations to inform species listing and assist management and conservation policies at national and international levels. Planned Outputs • A report outlining the results of genetic and movement analysis of hammerhead shark populations in northern Australia, Indonesia and Papua New Guinea including identification of BIAs (aggregation sites) and use of CMRs where possible; revised conceptual models of stock structure and species status assessments; and a summary of Indigenous knowledge and traditional use of hammerhead sharks. • Presentation of results to key stakeholders and end users • Policy Brief (Research Summary for Managers) that describes project outcomes • Manuscripts for scientific journals outlining the results of project components (eg, genetics, movement, Indigenous use and knowledge transfer) • Presentation of recommendations at scientific conferences • Communication of findings to the broader community via social media

This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "OzSET: Integration and publication of the Australian Surface Elevation Table dataset". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australia’s coastal floodplains and wetlands provide essential ecosystem services and have immense cultural value. They regulate water quality, moderate flood and storm damage, and provide habitat for marine life including commercial fish and shellfish species. These environments are threatened by accelerating rates of sea-level rise. A national approach is needed to monitor and assess the way coastal floodplains and wetlands are changing in response to sea level rise. A useful measure of resilience is the extent to which coastal wetland sediments can accrete vertically at a rate matching that of sea-level rise. Assessing the resilience, or vulnerability, of these environments requires measurements of rates of vertical accretion, subsidence and elevation gain across a range of coastal settings. The Surface Elevation Table-Marker Horizon (SET-MH) technique measures the vertical accretion of coastal wetland sediments. This enables assessment of whether wetlands are keeping pace with sea level rise (measured at tide gauges), or subsiding relative to local sea level rise and thus vulnerable to permanent inundation and loss. Australia’s network of Surface Elevation Tables is one of the most extensive in the world, consisting of over 200 benchmark monitoring stations from Westernport Bay, Victoria to Darwin Harbour, NT. The network has developed largely without national coordination, and the data gathered have not been readily available to the research community or research users. This project collated SET data on accretion, subsidence and elevation change in mangroves, saltmarshes, seagrasses and tidal freshwater forests, and provides an initial analysis of accretion and surface elevation trends. This information is vital to coastal risk assessment, estimating blue carbon sequestration, and modelling potential predicted changes in other ecosystem services. Outputs • Collation of data from existing Surface Elevation Table (SET-MH) stations [dataset] • Final Technical Report

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A4 - "The status of human-shark interactions and initiatives to mitigate risk in Australia". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Considerable political, public and media attention has recently been focussed on human-shark interactions, specifically surrounding shark attack and ways to mitigate this risk. Finding the most appropriate policy balance between conservation of sharks, maximising public safety and understanding the broader social and economic ramifications/drivers for doing so is a continuing challenge for Government. This project will review the status of human-shark interactions in Australia, provide a synthesis of current initiatives to reduce risk, review recent international efforts to address these issues and identify knowledge gaps to provide an informed base for determining the most appropriate future research and policy support. The project will develop a background document that: • Provides a synthesis of the current state of knowledge of shark-human interactions in Australia, focussing specifically on species such as white sharks, bull sharks and tiger sharks • Identifies what initiatives are currently underway nationally to address human-shark interactions including the status of current research as well as current management and policy initiatives. • Identifies technological developments within Australia and internationally in this space • Identifies lessons and experiences from these initiatives • Identifies issues and knowledge gaps • Provides guidance to the Department regarding further investment that is cognisant of State Government initiatives and requirements and ensure a coordinated national knowledge base for addressing these issues

This record provides an overview of the NESP Marine and Coastal Hub scoping study - "Scoping for an Australian Wetland Inventory: identifying knowledge gaps and solutions for mapping Australian marine and coastal wetlands". No data outputs were generated by this project. -------------------- Marine and coastal wetlands provide extensive ecosystem services—protecting shorelines, improving water quality, supporting healthy fisheries, promoting tourism, storing carbon, and holding cultural significance for Aboriginal and Torres Strait Islander people. Like many wetlands around the world, Australian wetlands continue to be threatened, degraded, and lost due to climate change, development, and other human activities. To support the Australian Government’s development of a national wetland inventory, this project assessed the current state of coastal wetland mapping across five key areas: seagrass, saltmarsh, intertidal macroalgae, shorebird habitat, and blue carbon. It identified major knowledge and inventory gaps through a combination of literature review and consultation with 73 end-users and experts, resulting in 25 targeted recommendations to guide future mapping and data integration. A summary of the status of mapping habitat attributes and ecosystem services such as blue carbon, coastal protection and shorebird habitat is available in the project's Final Technical Report. This report incudes recommendations to guide investment in high-demand areas and support nationally consistent wetland management and reporting to address key 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]

This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "A national framework for improving seagrass restoration". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Seagrasses provide resources and ecosystem services critical to the health of coastal ecosystems and human populations. They increase water clarity, stabilise sediments and reduce coastal erosion, sequester carbon, and provide habitat and food to marine animals, including commercially important fish and invertebrates. Across Australia, the loss of >275,000 ha of seagrass meadows and associated ecosystem services—valued at AU$ 5.3 billion—has contributed to the long-term degradation of estuarine and coastal marine ecosystems. Restoration of seagrass is critical for improving the health and function of these ecosystems and sustaining coastal communities and industries that depend on them, yet restoration projects to date typically occur at small scales, driven by local priorities and with variable success. This project addressed this problem by bringing together scientists and key stakeholders to collate knowledge on seagrass ecology and restoration, and generated a framework to scaling-up restoration nationally. A national workshop with experts identified a shortlist of drivers key to restoration success, including sediment dynamics, microbial communities, hydrodynamics, and species interactions. It highlighted the importance of incorporating seagrass genetics and life histories into site and donor material selection to improve long-term resilience. New technologies such as eDNA, automation, and AI were also assessed for their potential to improve monitoring and reduce costs, while standardised methodologies and molecular tools were recommended to track microbial indicators and site suitability. A key insight from the workshop was the central role of sediment processes in feedback loops that determine seagrass health—providing a foundation for more effective, scalable restoration strategies. On-ground case studies were conducted in Western Australia and New South Wales to test the proposed restoration framework in collaboration with Indigenous and community partners: sediment quality assessment and manipulation (Gamay Rangers, UNSW); seed and seedling capture using sediment-filled hessian tubes (Malgana Rangers, UWA); and large-scale seed collection for seed-based restoration through the 'Seeds for Snapper' initiative (OzFish and UWA). These trials demonstrated the effectiveness of community-led restoration and reinforced the potential of seed-based methods for scaling up seagrass recovery. Outputs • Effect of sediment quality and manipulation on seagrass transplant success [field data] • Locations and health of beachcast fragments of Posidonia in Botany Bay [field data] • Effect of engineering hydrodynamics (by use of hessian socks) on seagrass transplant success [field data] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub scoping study - "National Areas of Interest for Seabed Mapping, Characterisation and Biodiversity Assessment". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Seabed and marine biodiversity data are time-consuming and costly to collect, so it is imperative that acquisition is focused on areas that align with end user priorities. The value that different stakeholders place on seabed and biodiversity data can be difficult to determine. Therefore, a shared process for identifying survey priorities is required to ensure the maximum shared benefit of future survey investment across research users, funding agencies, infrastructure providers, as well as the wider marine research community. The project aimed to assist with the planning and prioritisation of marine surveys (both physical and biological) by scoping a prioritisation framework for marine surveys undertaking physical and biological seabed data collection in Australia. Focused workshops and targeted engagements with seabed mapping organisations were used to develop a standard set of metadata for agencies to define spatial Areas of Interest (AOI). The standard metadata were used in a prototype prioritisation framework that allows users to transparently and consistently rank and prioritise survey work or data delivery processes. The prioritisation is then based on rankings established by defined sets of criteria. A web-based AOI submission tool and mapping publication service was then developed for these defined areas as part of the AusSeabed Survey Coordination Tool. Adoption of this tool facilitates the development of an interim national areas of interest product to inform future survey planning. This product supports both the needs of Parks Australia's network Science Plans, and consideration of information needs for Indigenous Protected Areas within Sea Country. Outputs • National Areas of Interest polygon & interactive map [dataset] • Code for Survey Coordination Tool [Github Repo] • Final Report with Value Prioritisation Framework [written]

This record provides an overview of the scope and research data outputs of NESP Marine Biodiversity Hub Project E2 - "Characterising anthropogenic underwater noise to improve understanding and management of acoustic impacts to marine wildlife". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Shipping noise is a marine pollutant that contributes significantly to the marine soundscape and is a stressor of marine animals, particularly marine mammals. In Australia, the characterisation and actual impacts of shipping noise on species behaviour are not clearly understood and information is needed. This research will provide quantitative spatial and temporal maps of shipping noise to inform on noise exposure and impacts to MNES within the EEZ and in WHA’s. The outputs will provide key information to marine management agencies such as DoEE, AMSA and GBRMPA to help them meet responsibilities and obligations under international and national law and policy to minimise the impacts of shipping noise on MNES. Planned Outputs • A suite of maps of chronic shipping noise for key areas and species of concern, identifying key management areas and gross polluters. • A database of ship source spectra for predominant large vessels • A paper on improved methods or ambient noise estimation • Report on the quantification of shipping noise on Matters of National Environmental Significance • Final report on the characterisation of shipping noise in Australia

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project A1 - "Northern Australian hotspots for the recovery of threatened euryhaline species". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Euryhaline elasmobranchs represent over half of the EPBC-listed threatened sharks and rays, with northern Australia of national importance for this threatened species community. Critical information gaps remain, limiting the implementation of Recovery Plan objectives. This project will fill many data gaps through the application of acoustic telemetry, traditional and advanced molecular research (population genetics and close-kin mark-recapture), life history studies and Indigenous knowledge and education. End-users, primarily the Department of the Environment, state and territory fisheries and wildlife agencies, and Indigenous organisations, will be provided with information necessary to improve management and facilitate recovery of these threatened species, focusing on three themes: (1) Monitoring and understanding euryhaline species; (2) Indigenous partnerships for management of euryhaline species, and; (3) Knowledge for the reassessment of river shark status. Planned Outputs • Updated assessment of river shark status • Manuscripts on ecology and status relevant to the management of threatened euryhaline species • Manuscripts on optimal design of acoustic receiver arrays and statistical methods for estimating mortality • Threatened marine species education package for Indigenous communities • Media releases around key field and engagement activities • Data and information outputs of this project will include distribution, extent of occurrence and area of occupancy estimates for key marine species, Indigenous knowledge on key species distribution and occurrence, mortality and survivorship data on key species, the first data on river shark age determination (an essential component of understanding demography), molecular data on population structure and population connectivity of key species, and lower population size estimate for Glyphis garricki. Data will be housed on appropriate explorable databases and made fully available to DOE • Refining the identification of biologically important areas (BIAs) within the NT and WA for threatened euryhaline elasmobranchs (using published BIA protocols)
