  • The Seamap Australia National Benthic Habitat Layer (NBHL) is a nationally synthesised database of seafloor habitat data, classified according to the Seamap Australia National Benthic Habitat Classification Scheme (https://vocabs.ardc.edu.au/viewById/129). In generating the Seamap Australia NBHL, datasets from data providers around Australia are collated and centrally hosted by IMAS (UTAS). Through time, some datasets become superseded by newer, more accurate data for the same region (improved data collection or processing methodology). This record aggregates all habitat datasets that have been collated as part of the Seamap Australia project, but are no longer considered the most accurate/up to date habitat for a particular region and have been superseded by another product. The parent record for the Seamap Australia NBHL provides an aggregation point for all "current" habitat datasets: https://metadata.imas.utas.edu.au/geonetwork/srv/eng/catalog.search#/metadata/4739e4b0-4dba-4ec5-b658-02c09f27ab9a

  • 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.

  • The Seamap Australia spatial data layer is a nationally synthesised data product of seafloor marine habitat data. Australian continental shelf benthic habitat layers in GIS format were collected from various stakeholders around the country. Through compiling all of these data sets, we established a controlled vocabulary, reviewed by ANDS and external independent assessors, to produce a national classification of marine habitats. This national marine habitat classification scheme complements work undertaken by the National Environmental Science Program (NESP) Marine Biodiversity Hub (Theme D). The Seamap Australia product is of national importance and highlights the diversity of benthic habitats around our marine estate. This is the first edition of a seafloor marine habitat data layer that seamlessly brings together data from each of Australia’s state and territory marine habitat databases. Seamap Australia is a constantly evolving product as we continuously improve our skills in standardising, collating and sharing marine spatial data. This record describes a static version of the Seamap Australia national data layer as of 28/11/2018. The most current version of the data is available from the Seamap Australia website [http://seamapaustralia.org/map]. We envisage that the 'live' product will be constantly developed and updated as future surveys continue to improve our knowledge of our vast marine estate.

    The ICIN (2023) Indigenous Rights and Interests (Carbon and Nature Repair) Dataset is a continental wide spatial dataset that identifies the legally recognised Indigenous rights and interests that give rise to rights under the Australian Governments ACCU Scheme (and future Nature Repair Market) (land and sea). The dataset developed was based primarily on publicly available spatial datasets, complemented by numerous private information sources. The analysis was undertaken at the continental scale, using a systematic, objective process to define the Indigenous estate. It is acknowledged that there may be some errors, and that Indigenous land and sea interests are broader than what is presented in the maps/dataset.

    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 (ME) Depth 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 ME Depth 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.

The Seamap Australia NBHL can be viewed, analysed and downloaded from the Seamap Australia data portal (https://seamapaustralia.org/map) – a national repository of seafloor habitat data and a decision support tool for marine managers. All habitat datasets in the Seamap Australia data portal, including the NBHL and all local- to regional-scale contributing datasets, are available for download. The Seamap Australia NBHL is a data collection of national importance and highlights the diversity of benthic habitats across Australia’s marine estate. This is the first Australian habitat dataset that seamlessly consolidates data from each of Australia’s state and territory providers. This dataset should be considered a “live” asset and will continue to develop as more suitable validated habitat data becomes available for inclusion, and improvements in data collection and analysis techniques enhance its resolution and currency. 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_National_Benthic_Habitat_Layer A download link for the full dataset is supplied in the “Online resources” section of this record, along with download links to older versions of the dataset. Note that data is now only available in Geodatabase (.gdb) format as it exceeds Shapefile size limits.
