    "Site Condition Monitoring has been (SCM) undertaken to determine whether the status of the special interest features which underpin the designation of habitats or areas are being maintained, and to guide site management action where appropriate. This study aimed to provide additional baseline data against which future changes can be measured to support Natural England’s overall programme of monitoring and surveillance of the sites into the future."

    This map shows subtidal reef habitats in Kilkieran Bay. MBES bathymetry and its derivatives slope, rugosity and variability, were used in a Random Forest model trained using video sample data to predict high level EUNIS (version 2022) habitats. The MBES bathymetric data were collected as part of the Irish national seabed mapping programme - INFOMAR.

    The dataset provides full-coverage maps of the habitats and biotopes in the German Baltic Sea at a resolution of 1 x 1 km for the entire region and at 50 x 50 m resolution in specific areas. We combined geological and biological surveys to map the seabed and collected extensive data to classify different habitats and their associated benthic communities. Using newly established national guidelines and predictive habitat modelling, we produced highly accurate maps. For upload to EMODnet four separate maps were made: - Broad Habitat Types according to the Marine Strategy Framework Directive (MSFD). - Annex I Habitat types - Habitat types classified according to the Baltic Sea-wide HELCOM underwater biotope and habitat classification (HUB) - other habitat types, OHTs for German marine waters include biotope types according to S30 of the German Federal Nature Conservation Act (BNatSchG), according to the European Habitats Directive (92/43/EEC), as well as the Baltic Sea-wide HELCOM Red List types

    Predictive Biological Zone layer produced by EMODnet Seabed Habitats as an input layer for the 2023 EUSeaMap broad-scale habitat model. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to the Barents Sea in the North. The map of biological zone was produced using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions. The model is produced in R and Arc Model Builder (10.1). The model was created using raster input layers with a cell size of 0.00104dd (roughly 100 meters). The model includes the sublittoral zone only (Infralittoral to Abyssal zone). An accompanying confidence layer is available for viewing and download from EMODnet Seabed Habitats. Reports detailing the methods used in the previous versions of EUSeaMap (v2019 and V2021) are linked in online resources a new report is in progress.

    Confidence in the classification of substrate type in the 2023 EUSeaMap broad-scale predictive habitat map. Values are on a range from 1 (Low confidence), 2 (Moderate confidence), 3 (High confidence). Substrate type is one of the layers of information used to categorise physical habitat types in EUSeaMap; these layers of information are collectively known as 'habitat descriptors'. The substrate layer confidence was obtained from reclassification and standardisation of the confidence scores associated with each primary layer used to create the Substrate types layer. A report on the methods used in the 2023 version of EUSeaMap and reports on previous versions (v2019 and V2021) are linked in Online Resources.

    Confidence in the classification of: - the Marine Strategy Framework Directive (MSFD) Benthic Broad Habitat Types (V. 2017) - the EUNIS 2019 habitat types - the Helcom Hub regional classification system habitat types - the Barcelona Convention classification system habitat types in the EUSeaMap (2023) broad-scale predictive habitat map. Values are 1 (Low confidence), 2 (Moderate confidence) or 3 (High confidence). The final habitat type is classified by overlaying several layers of information; these layers of information are collectively known as 'habitat descriptors'. Habitat descriptors differ per region but include: Biological zone Energy class Oxygen regime Salinity regime Seabed substrate Riverine input The confidence in the classification of the habitat type is taken as the minimum of the confidence in all of the relevant habitat descriptors at that location. Confidence values are also available for each habitat descriptor and input data layer.

It is important to note that a habitat type confidence score is only relevant to that particular level of the classification system.

    Confidence in the classification of biological zones in the EUSeaMap (2023) broad-scale predictive habitat map. Values are on a range from 1 (Low confidence), 2(Moderate confidence) and 3 (High confidence). Biological Zone is one of the layers of information used to categorise physical habitat types in EUSeaMap; these layers of information are collectively known as 'habitat descriptors'. Confidence in the classification of a Biological Zone at any location is driven by both the confidence in the values of the input variables, and the confidence in the classification based on proximity to, and uncertainty in, the boundary between classes (i.e. areas closer to a boundary between two classes will have lower confidence). Layers are also available showing confidence in the values of the input variables used to model Biological Zones. Detailed information on the modelling process is found in the EMODnet Seabed Habitats technical reports and its appendices (links in Resources).

    Output of the 2023 EUSeaMap broad-scale predictive model, produced by EMODnet Seabed Habitats. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to the Barents Sea in the north. The map was produced using a "top-down" modelling approach using classified habitat descriptors to determine a final output habitat. Habitat descriptors differ per region but include: Biological zone Energy class Oxygen regime Salinity regime Seabed substrate Riverine input Habitat descriptors (excepting Substrate) are calculated using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions. The model is produced using R and Arc Model Builder (10.1). The model was created using raster input layers with a cell size of 0.00104dd (roughly 100 metres). The model includes the sublittoral zone only; due to the high variability of the littoral zone, a lack of detailed substrate data and the resolution of the model, it is difficult to predict littoral habitats at this scale. EUSeaMap is classified into EUNIS 2019 level 3 (or more detailed levels where appropriate), EUNIS 2019 level 2 , EUNIS 2007-2011, the MSFD benthic broad habitat types, the HELCOM HUB classification in the Baltic, and the recently revised habitat classification in the Mediterranean. In the Black Sea, EUSeaMap is not classified into EUNIS 2007-2011 (due to inapplicability), but is classified according to a classification that was developed by EMODnet Seabed Habitats (Populus et a, 2017, and for a revised version Vasquez et al, 2020, See Online resources). Reports that provide methods used for the classification of the predicted habitats into the new 2019 EUNIS classification, regional classifications, and MSFD BBHT (v.2017) are linked in Online Resources.

    Confidence in the classification of energy level in the EUSeaMap (2023) broad-scale predictive habitat map. Values are on a range from 1 (Low confidence), 2 (Moderate confidence), 3 (High confidence). Energy level is one of the layers of information used to categorise physical habitat types in EUSeaMap; these layers of information are collectively known as 'habitat descriptors'. Confidence in the classification of an energy level at any location is driven by both the confidence in the values of the input variables, and the confidence in the classification based on proximity to, and uncertainty in, the boundary between classes (i.e. areas closer to a boundary between two classes will have lower confidence). Layers are also available showing confidence in the values of the input variables used to model energy levels (kinetic energy at the seabed and wave exposure).
