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.

This record provides an overview of the NESP Marine and Coastal Hub Research Plan 2024 project "De-risking nature repair activities in Australian coastal and marine ecosystems". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Scaling up marine and coastal restoration and nature-based solutions (NbS) (“nature repair”) in Australia is necessary to achieve national and international commitments to biodiversity and climate change mitigation and adaptation. The goal of this project is to guide coastal marine nature repair in Australia at scales relevant to help meet national targets through the following aims: 1) Update a stocktake of the coastal and marine restoration and NbS activities which have occurred in Australia. 2) Develop the evidence-base to de-risk coastal and marine nature repair. 3) Scope a forward-looking coordinated framework to support continued implementation of investments in nature repair of Australia’s coastal and marine ecosystems. Addressing these aims is required to move forward beyond uncoordinated efforts to achieve effective seascape-scale interventions that support the Nature Positive Plan and international targets. Outputs • Updates to Australian Coastal Restoration Network database, and the Living Shorelines Australia database [dataset] • Draft national framework for coordinated nature repair [written] • 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 "Environmental DNA for measuring offshore marine biodiversity: what can DNA in water collected from the RV Investigator tell us?". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Environmental DNA (eDNA) is genetic material that is found in the environment. In marine ecosystems eDNA is ubiquitous in seawater and is derived from everything from bacteria to invertebrates and fishes. eDNA can be recovered by filtering water samples and then used it to characterise biodiversity. Using environmental DNA (eDNA) found in seawater to get a snapshot of the species present in an area is an emerging technology with diverse applications in marine ecosystem monitoring. This project will collect a large eDNA dataset during the Southeast Australian Marine Ecosystem Survey (SEA-MES). The eDNA samples will be taken from the RV Investigator throughout the water column at offshore sites stretching from Tasmania to NSW, including sites within the South-east Marine Park Network. The voyage includes parallel collection of biodiversity data using a suite of conventional methods (nets, cameras, and acoustics) which will allow for an assessment of how eDNA compliments these approaches. The project will provide a new baseline and unique eDNA-based perspective on the biodiversity of the southeast Australian marine region. It will also allow for evaluation of eDNA sampling methods and guidance for design of effective, scalable, and non-extractive biomonitoring tools for marine ecosystems. Outputs • eDNA sequences with associated collection metadata (x2 voyages x50 sites) [dataset] • Final project report [written]

This project updates the 2019 predictive benthic habitat map for this region, extending past the subtidal zone of the harbour to include intertidal habitats. The project worked with collaborators to synthesise existing data sets for inclusion in benthic habitat mapping process. Hydrodynamic model variables were updated and new digital elevation data included to provide a more accurate representation of the bed shear stress, waves and current. LiDAR surveys were conducted to fill in the gap between the IX bathymetric survey and the high tide water mark. The LiDAR survey data extended the existing bathymetry data. A total of 30 towed video transects were conducted in areas predicted to have a high probability of benthic fauna occurrence based on the existing predictive model. The benthic habitat model was updated to include NTG historical data, new towed video data, hydrodynamic and light data.

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 "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 "Development of regional modelling and risk assessments to inform offshore renewable decision-making". 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 (ORE) development, with several regions earmarked for wind farms on the eastern and south-eastern coasts. In considering the environmental acceptability of wind energy projects, the Department of Climate Change, Energy, the Environment and Water (DCCEEW) will assess potential risks to the recovery of populations listed under the Environment Protection and Biodiversity Conservation Act (EPBC Act 1999). The assessment process will consider cumulative environmental impacts at a regional or even ocean basin-scale, in addition to environmental factors specific to ORE. Additionally, the National Offshore Petroleum Safety and Environment Authority (NOPSEMA) has identified the need for improved understanding on species, processes and industry activities to support impact and risk assessment. This project will demonstrate the use of two kinds of modelling (whole-of-ecosystem modelling and individual species modelling) to estimate the impacts and risks of installing ORE infrastructure in the Gippsland declared region. The project will use the Impact pathways defined by DCCEEW to structure its approach and methods, and will work with DCCEEW and NOPSEMA to identify priority species and associated data needs. The project will use the recently declared Gippsland region as a case study, together with the 12 ORE impact pathways identified by DCEEW, to contextualise the quantitative modelling and cumulative risk calculations that will be performed. Outputs • Species-specific population models for key threatened and migratory species for the Gippsland ORE region [spatial outputs] • Outputs from Whole of Ecosystem (WoE) modelling [risk-based impact spatial outputs] • Final project report [written]
