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 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 "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]

The Blue Economy CRC has commissioned a team of experts from CSIRO to support the collation of data and produce sets of maps as inputs to the Futures of Seafood study State of Play (Work Package 1). The study team greatly appreciate the efforts taken by jurisdictional governments to supply the data, and the ongoing engagement on the production of these maps. The team is now finalising the jurisdictional map sets and is seeking final review of the data. Once reviewed, these maps will be included in the Futures of Seafood outputs that will be available on https://futuresofseafood.com.au/

The datasets contain summaries of Commonwealth logbook data on catch and effort distribution for AFMA managed commercial fisheries in state marine and estuarine waters. The logbook data has been recorded and submitted to AFMA by commercial fishers. The data are aggregated to produce summaries of total catch and effort by fishery at a 0.1 degree resolution where 5 boats or more operate. For areas where less than 5 boats operate the data is shown as confidential. The data was mapped using 5 year - financial year periods; 2003/04 to 2007/08, 2008/09 to 2012/13, 2018/19 to 2022/23, and 1 year; 2022/23.

This dataset is a mosaicked product of all publicly available bathymetry data within the Australian Exclusive Economic Zone (EEZ). The data package consists of 8x bathymetry mosaics (and associated bathymetry derivatives: hillshade, slope, aspect) for each of the 8x Parks Australia Management Effectiveness Ecosystem Component depth zones ("Ecosystem Zones"). The grid resolution of the mosaics has been guided by the depth gridding recommendations of the AusSeabed Australian Multibeam Guidelines (2020) to produce the following mosaics: • shallow zone (0-30m): 10m resolution • mesophotic zone (30-70m): 10m resolution • rariphotic zone (70-200m): 10m resolution • upper-slope zone (200-700m): 32m resolution • mid-slope zone (700-2,000m): 64m resolution • lower-slope zone (2,000-4,000m): 128m resolution • abyss zone (4,000-6,000m): 210m resolution • hadal zone (>6,000m): 210m resolution A systematic prioritisation approach was used to preferentially use newer, high-resolution, and cleaner bathymetry inputs from remote sensing (multibeam, singlebeam, satellite, seismic etc), with Digital Elevation Models (DEM) used as foundational data in regions where survey data was not available. This approach optimised spatial resolution by preserving higher resolutions in shallower waters as supported by the data, while also ensuring the output datasets remain manageable for downstream applications. The result is suite of depth-stratified bathymetry mosaics and associated derivatives that provide full coverage of Australia's marine estate (clipped to the boundaries of the Australian Exclusive Economic Zone (EEZ)). All publicly available bathymetry data as at July 2024 for was included. Data can be visualised and used in GIS packages as maps of hillshaded bathymetry and hillshaded slope at the following WMS endpoints: • bathymetry: https://geoserver.imas.utas.edu.au/geoserver/bathy_composites/AusEEZ_bathy_composite_multires/wms?request=GetCapabilities&service=WMS • hillshade: https://geoserver.imas.utas.edu.au/geoserver/bathy_composites/AusEEZ_bathy_hillshade_composite_multires/wms?request=GetCapabilities&service=WMS • slope: https://geoserver.imas.utas.edu.au/geoserver/bathy_composites/AusEEZ_bathy_slope_composite_multires/wms?request=GetCapabilities&service=WMS • aspect: https://geoserver.imas.utas.edu.au/geoserver/bathy_composites/AusEEZ_bathy_aspect_composite_multires/wms?request=GetCapabilities&service=WMS • aspect-slope (for mapping applications only): https://geoserver.imas.utas.edu.au/geoserver/bathy_composites/AusEEZ_bathy_aspectSlope_composite_multires/wms?request=GetCapabilities&service=WMS Data is available for download in the following packages (each structured as 8x mosaics for each Ecosystem Zone at the gridding resolution specified above): (1) bathymetry composites; (2) hillshade composites; (3) slope composites; (4) aspect composites. An ancillary Shapefile footprint index file is also available showing the source data used in generating each region of the mosaics. Note that minimal cleaning of input data was conducted, and no attempt was made to smooth or blend the transitions between swath edges, or between swaths and the underlying DEMs. Consequently, noise and edge effects between adjacent input data may be visible. This should be considered when interpreting the data, and the data should not be used for navigational purposes. See the Lineage section of this record for full methodology.

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 project aimed to identify and map critical habitats for Australian sea lions (Neophoca cinerea) to assess the ecological value of different habitats, and identify risks to their populations. Video imagery, GPS, time-depth and accelerometer/magnetometer data was captured from eight adult female Australian sea lions from Olive Island (n=4) on the western Eyre Peninsula and Seal Bay (n=4) on Kangaroo Island in South Australia. Sea lions were instrumented with animal-borne cameras with integrated accelerometers/magnetometers (CATS Cam, 135 x 96 x 40 mm, 400 g) and satellite-linked GPS loggers with integrated time-depth recorders (SPLASH-10, Wildlife Computers, 100 x 65 x 32 mm, 200 g). Sea lions were sedated and anaesthetised and bio-logging instruments were glued to the pelage on the dorsal midline. Bio-logging instruments were recovered after a single foraging trip (~1-6 days). The data collected in this project provides fundamental information on critical benthic habitats for Australian sea lions, the differences in foraging behaviour of individual sea lions, and their prey preferences. This information improves our understanding of threats to sea lion populations and will support future conservation actions to recover the species.
