    Composite data holdings of habitat point data from groundtruthing data in European waters. Data are collated by EMODnet Seabed Habitats partners from a variety of source datasets and conformed and standardised into the portal's Darwin-core compliant schema. Habitats are described in a variety of classification systems, including EUNIS (European Nature Information System), Habitats Directive Annex I, Marine Strategy Framework Directive Benthic Broad Habitats, Regional sea conventions (HELCOM HUB, OSPAR) and local classifcation systems. Sampling methods are standardised to NERC vocabulary server P01 parameters or ICES vocabulary concepts where possible.

    Data holdings of polygonal habitat maps in European waters. Data are collated by EMODnet Seabed Habitats partners from a variety of source datasets and conformed and standardised into the portal's INSPIRE-compliant schema (for more information, please see https://emodnet-seabedhabitats.eu/def . Habitats are described in a variety of classification systems, including EUNIS (European Nature Information System), Habitats Directive Annex I and local/other classifcation systems. Ownership of the individual maps is retained by the original owners, for more information please see the individual metadata record tied to the map, which can be seen in the query response. Maps are available indivudually through EMODnet Seabed Habitats' "maplibrary" OGC service endpoints: For WMS (view) access to maps, please use https://ows.emodnet-seabedhabitats.eu/emodnet_view_maplibrary/wms? For WFS (download) access to open maps, please use https://ows.emodnet-seabedhabitats.eu/emodnet_open_maplibrary/wfs?

    Updated habitat map resulting from an intergrated analysis of the acoustic and ground truth survey data in 2014 (onboard the RV Cefas Endeavour). Broadscale habitats at each ground truth station were used to inform a semi-automated mapping process using object-based image analysis (OBIA). The majority of the seabed was classified as the BSH 'A4.1 High energy circalittoral rock/A4.2 Moderate energy circalittoral rock', with a with a large sediment bank in the north of the rMCZ made up of the BSHs 'A5.1 Subtidal coarse sediment' and 'A5.2 Subtidal sand'.

    Updated habitat map resulting from an intergrated analysis of the acoustic and ground-truth survey data from 2014 (onboard the RV Cefas Endeavour). Sediment types at each groundtruthing station were used to inform a semi-automated process of map production using object-based image analysis (OBIA). The majority of the seabed was classified as 'A5.4Subtidal mixed sediments', with patches of 'A5.1 Subtidal coarse sediment'and 'A5.2Subtidal sand'.

    Broadscale habitat (EUNIS level 3) for Hythe Bay (rMCZ) recommended Marine Conservation Zone (rMCZ) Updated habitat map resulting from an intergrated analysis of the acoustic and ground-truth survey data from 2012. The ground-truthing survey was carried out by the Environment Agency (EA) on the 26th March 2012 using the MV Sea Vigil. The site is predominantly characterised as A5.3 Subtidal mud.

    Updated habitat map resulting from an integrated analysis of the 2013 dedicated survey data (collected on cruise CEND0613) for South-West Deeps (West) recommended Marine Conservation Zone (rMCZ). A new habitat map for the site was produced by analysing and interpreting the available acoustic data and the ground-truth data collected by the dedicated surveys of South West Deeps West rMCZ. The process is a combination of two approaches, auto-classification (image analysis) and expert interpretation. The routine for auto-classification is flexible and dependent on site-specific data, allowing for application of a bespoke routine to maximise the acoustic data available. ArcGIS was used to perform an initial unsupervised classification on the supplied backscatter image. The single band backscatter mosaic was filtered and smoothed prior to the application of an Iso cluster/maximum likelihood classification routine. For further information, refer to the South-West Deeps (West) rMCZ Post-survey Site Report.

    Broadscale habitat (EUNIS level 3) for Compass Rose recommended Marine Conservation Zone (rMCZ). Seabed texture polygons mapped using expert interpretation of acoustic data (MBES bathymetry and backscatter, and bathymetry compiled for Defra(Astrium, 2011)) and ground-truthing data from PSA analysis and image (stills and video) classification.

    A broadscale habitat map was produced by analysising and interpreting the acoustic and ground truth data collected at South Rigg rMCZ. Acoustic data was used to identify areas of Rock and sediment and groundtruthing data was used to divide the sediment areas into one of the four sediment classes, namely coarse sediment, sand, mud and mixed sediment. These areas were then divided into littoral and subtidal zones and different energy areas (Low, Moderate or High). These classes could then be classified using EUNIS.

    A broadscale habitat feature class was created to illustrate the predicted extent of broadscale habitats present at Slieve na Griddle rMCZ. These broadscale habitats include 'Subtidal mud' and 'Low energy circalittoral rock' as determined from particle size analysis of sedimen grab samples and descriptive analysis of still images from underwater camera data. The assigned classes of each ground-truth station were used to inform the semi-automated process of map production using object-based image analysis (OBIA).
