This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "An Indigenous-led approach to advance the health and wellbeing of Tebrakunna Country and people of the Coastal Plains nation, north-eastern Tasmania". No data outputs are planned for this project. -------------------- This research is an Indigenous led co-designed project between Melythina Tiakana Warrana Aboriginal Corporation (MTWAC) and the University of Tasmania spanning all four NESP Hubs. It is focusing on Healthy Country Planning (HCP) processes at Tebrakunna as the Coastal Plains Nation are re-connecting to Ancestral land and sea Country. Through MTWAC’s strategic direction, key priorities and areas of interest there is a core focus on concepts surrounding healthy Country and healthy people that will develop throughout the project and contribute to the HCP for MTWAC. MTWAC aims to be a sustainable organisation, manage culture and heritage, and contribute to healing and wellbeing and broader community engagement. To achieve these priorities, through MTWAC-led HCP processes, Western scientists will work closely with MTWAC, including Indigenous Researchers within this community, Tebrakunna Country Ranger Program and HCP Facilitators. The project will assess priority values, targets, threats and viability of land and sea of Tebrakunna Country. We will determine within budget and time constraints where efforts will be best targeted to improve and protect the health of Country and people at Tebrakunna. Monitoring and evaluation, including of the wellbeing of people and Country, through measurable, community-developed goals and strategies will improve capacity and employment opportunities of MTWAC and the Tebrakunna Rangers. Outputs • Report characterising Coastal Country, including threats and opportunities assessment [written] • Co-designed wellbeing framework, methods and tools [written] • Final project report [written] ---no data outputs are planned for this project---

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Assessing the vulnerability of southern right whale and blue whale populations to disturbance from windfarm developments". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australia is entering a phase of rapid offshore renewable energy development, with several marine regions earmarked for wind farms. Underwater noise generated by the construction and operation of large wind turbines may affect species such as whales that rely on their acoustic environment to feed, breed and survive. This desktop study used available data and expert elicitation to develop an interim Population Consequences of Disturbance (iPCoD) model for blue whales and southern right whales in relation to one or multiple offshore wind farm developments off Portland and Gippsland, Victoria. This method has been used internationally to assess the impacts of offshore wind farm developments, including for harbour porpoises in British waters. The model follows a decision pathway to consider factors such as: • when and where development activities overlap with populations; • the proportion of populations affected; • the life stages and reproductive phases affected; and • the chances of repeated disturbance. The model was used to predict the timing and location of cumulative impacts of the proposed activities at a regional scale, identifying which species are at ‘high-risk’ and are a priority for further research; noise levels mitigation measures required to adequately reduce the risk of compromised population viability; what research is needed to better understand population-level consequences of noise; and which mitigation measures can substantially reduce the risk of population-level effects. The iPCoD model will be able to be updated as new data become available, and is relevant for assessment against other ocean-based activities such as oil and gas infrastructure and carbon capture and storage. Outputs • iPCoD model outputs [dataset] • Species distribution maps, as derived for existing observational data [spatial visualisation/story] • Final Project Report [written]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Unbroken whispers: the ripples connecting sea kin". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Knowledge, in all its forms, is key to effectively protecting and recovering threatened and migratory whales and dolphins. Indigenous ecological knowledge (IEK) has guided Indigenous peoples through many uncertain climate and ecological fluctuations. IEK has also been used as part of protected area and species management for many thousands of years. More recently, IEK has shown huge potential to contribute to our understanding of threatened and migratory whales and dolphins, but this knowledge has not historically been collated, analysed or properly considered. Consequently, there is an absence of Indigenous perspectives and use of cultural knowledge informing the protection and recovery of EPBC listed threatened and migratory species. This Indigenous-led project will identify and share (where appropriate) cultural knowledge of relationships with whales and dolphins, and connections between land, sea and sky. Indigenous communities will participate in research that explores cultural ideology around kinship and responsibilities to kin, through expressing the knowledge, values and concerns they hold for whales and dolphins. The acquired knowledge and methods will support the cultural governance of sea Country by Indigenous communities and organisations, and policymaking, implementation and review by government agencies in relation to resource use and conservation. Outputs • GIS visualisation package of key geospatial layers related to connecting land and sea in the context of cultural keystone species [dataset] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Assessing the condition of natural values within priority temperate Australian Marine Parks to evaluate management effectiveness". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Parks Australia has developed an adaptive management approach to the Australian Marine Parks (AMPs), which cover 48% of Australia's Exclusive Economic Zone. Key to the success of this framework is robust biological and ecological data to assess the performance of management approaches. The project will collect data to measure the trend in natural values to allow for evaluation of management performance at various levels on the continental shelf regions of four AMPs: Hunter (Temperate East Network), Beagle (South-east Network), South-west Corner and Geographe (South-west Network). These AMPs were selected based on previous partnerships between Parks Australia and NESP projects. This project aligns with Parks Australia’s science plans, supporting adaptive management and addressing emerging threats. Marine sampling and monitoring Standard Operating Procedures (SOPs) will be used to systematically collect data that will provide trusted scientific evidence for decision-makers, aiding in effectively safeguarding the ecological integrity of these marine ecosystems. Outputs • Fish scoring data from BRUV, BOSS and ROV platforms [dataset] • Benthic imagery with annotations from AUV platform [dataset] • Lobster catch data [dataset] • Spatially-referenced highlight videos/imagery for communication purposes [dataset] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Enhancing monitoring approaches to evaluate the abundance, life history and critical habitats of the endangered Australian sea lion". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The Australian sea lion (ASL; Neophoca cinerea) is Australia’s only endemic pinniped. Populations have declined by more than 60% over the last 40 years to extremely low levels, leading to its endangered status. Known threats to the species include fisheries bycatch, disease, pollution, entanglement in marine debris, and climate change. Improving our understanding of the species’ abundance, life history and critical habitats is essential for evaluating these threats and guiding recovery actions but is challenging due to the species’ unique life-history and breeding biology, longevity, demersal foraging behaviour and occupancy of remote breeding habitat. This project aims to improve the monitoring and inform the management of Australian sea lions by developing cost-effective methods for acquiring abundance data from under-surveyed regions impacted by anthropogenic pressures. To do so, it will: • Apply drones to enhance monitoring at suitable breeding and haul-out sites • Develop efficient techniques to process and analyse demographic data so that survival and reproductive success estimates from a microchipped population at Seal Bay can be routinely updated; and • Continue to deploy underwater cameras on sea lions to identify and understand critical habitats and risks. Findings from these activities will underpin the National Recovery Team conservation efforts, in line with the Australian Government's Threatened Species Action Plan and Healthy Country plans. Outputs • Qualitative and qualitative spatial assessments of breeding sites from helicopter surveys in Recherche Archipelago [dataset] • Drone-collected photogrammetry, FLIR, thermal imaging and LiDAR data [dataset] • Demographic results from analysis of Seal Bay microchipping program [dataset] • Tracking data from sea lion-deployed tags: location, depth, time, temperature, light, acceleration [dataset] • Timestamped video footage from sea lion-deployed cameras [dataset] • Short non-technical summaries to distil the key findings and take-home messages [written] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Environmental concentrations of emerging contaminants in coastal stormwater". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Australia’s Waste Policy Action Plan, Threat Abatement Plan for the impacts of marine debris and Australia’s One Health Master Action Plan all refer to the need for emerging pollutants to be incorporated into contaminant guidelines. A scoping study conducted by NESP MaC Hub in 2022 (Project 1.16) determined there is a clear and consistent need for data on environmental concentrations of contaminants of emerging concern (CECs) and an assessment of their impact on ecological communities. To build an evidence-based understanding of the environmental concentrations of these contaminants and their ecological significance in Australian coastal waters, NESP MaC Project 2.4 was co-designed with end-users to determine environmental concentrations and potential ecological effects at selected wastewater treatment plant outfalls. In 2023, end-users stated a need for improving the temporal and spatial resolution of the current project. Project 2.4 used outputs of oceanographic simulations and other information to identify a small set of locations for sampling that are representative of a range of receiving water contexts. Spatial surveys of contaminants of emerging concern (CECs) in water and sediments were undertaken during the dry period to limit the potential for stormwater inputs, and only one time period was sampled. An implicit assumption of the sampling design was that stormwater also contains CECs and could confound the assessment of contaminants in wastewater. This project (4.22) is an extension of Project 2.4 and will determine the concentration of emerging pollutants in coastal stormwater, and in wastewater treatment plant (WWTP) effluent, and do so on a seasonal basis. Sampling will be undertaken in two key locations: Gamay (NSW) and Glenelg (South Australia). These are the same locations sampled in Project 2.4 (with a focus on WWTPs) which will enable the concentrations of CECs to be compared at stormwater locations. Outputs • Updates to the National Outfall Database for 2022/23, including proposed new attributes for collection [dataset] • Data from Gamay (Botany Bay) NSW including (1) contaminant levels in water and sediments (2) physico-chemical data; (3) microbial community and genetics composition of water and sediments [dataset] • Timeseries (seasonal) CEC data from wastewater effluent at Glenelg beach area (SA) [dataset] • [Possible] High-resolution temporal CEC data from a stormwater event in St Vincents Gulf [dataset] • Final project report [written]

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Grey Nurse Shark aggregations". For specific data outputs from this project, please see child records associated with this metadata. -------------------- The grey nurse shark (Carcharias taurus) has been protected in Australian Commonwealth waters since 1996. Although historically distributed across southern Australia, in October 2001 the grey nurse shark was listed as two separate populations with different protection listings under the EPBC Act of 1999: Critically Endangered in eastern Australia, and Vulnerable in Western Australia. Grey nurse sharks (GNS) tend to aggregate at specific sites along migration routes. There are currently 19 identified key aggregation sites along the eastern seaboard. Recent observations indicate that this definition requires revision to account for factors such as seasonal movements and to be applicable to the Western Australian population. This project aims to collate existing information on key aggregation sites and ‘new’ sites where GNS have been found to gather (both in eastern and western Australia). This information will be used to refine the definition of key aggregation site and develop criteria to allow assessment of new sites. This project will also investigate potential sites in Victoria where the least amount of information is available. Outputs • Spatial information on key Grey Nurse Shark aggregation sites [dataset] • Final project report [written]

The goal of the program was developing comprehensive inventories and maps of the distribution and abundance of physical and biological seabed habitats, seagrasses and benthic assemblages to provide baseline environmental mapping and a description of ecological patterns. The benthic habitat mapping was performed by utilising R/Python and Maxent software within the species distribution modelling domain. We correlated the probability of occurrence of individual benthic habitat classes with the environmental predictors developed form the multibeam hydroacoustic dataset. The data is presented as a maximum likelihood map incorporating all five prediction classes: (1- Macroalgae; 2- Filter Feeders; 3- Seagrass; 4- Hard Corals; 5- Bare seafloor). An updated version of this data are available (2022) Revised predictive benthic habitat map for Darwin Harbour. Report prepared for Department of Environment, Parks and Water Security. Australian Institute of Marine Science, Darwin, 127 pp.

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "Potential impacts of offshore wind developments on eastern Indian Ocean pygmy blue whales (Balaenoptera musculus brevicauda)". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Pygmy blue whales (Balaenoptera musculus brevicauda) are listed as Endangered under the Environment Protection and Biodiversity Conservation Act (EPBC 1999), and their distribution and Biologically Important Areas (BIAs) overlap with areas proposed for offshore renewable energy (ORE) development in Western Australia, South Australia, Victoria, and potentially NSW. This project will quantify the distribution and location of areas of residency (e.g., foraging) for eastern Indian Ocean pygmy blue whales, where these overlap with proposed ORE developments, and assess the potential impacts of these developments to the species in addition to existing impacts from other anthropogenic activities. The outputs from this project will assist government, regulators, proponents, and other stakeholders in the assessment and mitigation of ORE projects to this threatened species, and will identify future research and associated data collection needs. Outputs • Spatial layers quantifying the relative distribution including migratory corridors and foraging areas across the known eastern Indian Ocean pygmy blue whale range [dataset] • Spatial layers of habitat suitability distribution [dataset] • Spatial layers for human activities identified as key pressures in this study [dataset] • Spatial layers of cumulative impact score across the species' range including potential threats from ORE and existing threats from other industries [dataset] • Final project report [written]

The Seamap Australia National Benthic Habitat Layer (NBHL) is a compilation of benthic habitat datasets obtained from various sectors including research, government, industry and community sources, across Australia. Disparate datasets are integrated into a single national-scale benthic habitat database, and classified uniformly under a national classification scheme implemented as a controlled vocabulary (https://vocabs.ardc.edu.au/viewById/129). For acceptance into the 'formal' (validated_ Seamap Australia NBHL (see https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/4739e4b0-4dba-4ec5-b658-02c09f27ab9a), source habitat datasets must meet a set of Acceptance Criteria (documented in https://seamapaustralia.org/wp-content/uploads/2023/01/SeamapAustraliaDataAcceptanceGuidelines.pdf). Broadly speaking, for inclusion in the Seamap Australia NBHL, datasets must: (1) be well-described by metadata or associated documentation; (2) employ a single, consistent classification scheme which avoids non-deterministic or ambiguous terms; (3) bequality-controlled by the provider prior to contribution; (4) beacquired using an established and community-endorsed form of data collection (eg satellite, aerial or acoustic remote sensing); and (5) have documented evidence of ground-truthing validation at the time of data collection (e.g. drop camera, towed video, benthic grabs). This record describes habitat datasets that meet Acceptance Criteria 1-4, but *have not* been validated/ground-truthed and are therefore ineligible for inclusion in the formal Seamap Australia NBHL. They have been synthesised and uniformly classified using an identical methodology to the NBHL, but represent an intermediate collection of habitat datasets that would benefit from field ground-truthing in order to validate the habitat classifications. The Seamap Australia synthesis of unvalidated habitat datasets can be viewed, analysed and downloaded from the Seamap Australia data portal (https://seamapaustralia.org/map). This dataset should be considered a “live” asset and will continue to develop as more unvalidated habitat datasets are collected or made available. The most current (2024) version of the data is available from the following endpoints: WMS: https://geoserver.imas.utas.edu.au/geoserver/seamap/wms WFS: https://geoserver.imas.utas.edu.au/geoserver/seamap/wfs Layer name: SeamapAus_NBHL_unvalidated Various download options are supplied in the “Online resources” section of this record.
