  • UKSeaMap 2016 has been generated by JNCC and is a by-product of the 2013-2016 activities of the EMODnet Seabed Habitats 2013-2016 consortium. It is a composite of two broad-scale habitat maps, arranged in the following priority order: 1. A roughly 100 m* resolution broad-scale habitat map, which covers the majority of the UK shelf area. 2. EUSeaMap 2016, a coarser resolution** broad-scale habitat map, which covers all European seas (view/download on the EMODnet Seabed Habitats interactive map). Both of these datasets have been created using identical methods; the only difference is in the resolution of the seabed substrate input data and the source and resolution of the depth data. Classification systems: EUNIS habitat classification system, with additional deep sea zones MSFD predominant habitats The Marine Habitat Classification for Britain and Ireland Input data layers: Seabed substrate type Depth to the seabed Amount of light reaching the seabed Wave disturbance at the seabed Kinetic energy at the seabed caused by tidal currents and waves Outputs: Predictive seabed habitat map Confidence layers The map follows the EUNIS 2007-11 classification system where it is appropriate.

    Confidence in the classification of the EUNIS v 2019 habitat types in the EUSeaMap (2021) 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. Detailed information on the modelling process is found in the EMODnet Seabed Habitats technical reports and its appendices (links in Resources).

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

  • 90th percentile Kinetic Energy due to currents at the seabed in the Mediterranean Sea and Black Sea in N m2/s - Created for the EMODnet Seabed Habitats broad-scale habitat map (EUSeaMap 2016). This dataset is a raster composite of the outputs of several models, produced for display in the EMODnet Seabed Habitats. In the Black sea the data was derived from the Copernicus CMEMS project archives, the model resolution is 10km and it was run for the years 1971-1984; 1990-2001. In the Mediterranean Sea the data was derived from the Copernicus CMEMS project (resolution 7 km; years 1999-2011). In the Adriatic Sea the data was derived from the Tessa project archives (resolution 2.2 km, years: 2011-2014). Each dataset is available separately.

    Confidence in the classification of energy level in the EUSeaMap (2021) broad-scale predictive habitat map. Values are on a range from 1 (Low confidence) to 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). A report on the methods used in the 2021 version of EUSeaMap (Vasquez et al., 2021) and reports on previous versions (v2016 and V2019) are linked in Online Resources.

    This layer shows the current known extent and distribution of Coralligenous and other calcareous bioconcretions in the Mediterranean, collated by EMODnet Seabed Habitats. The purpose was to produce a data product that would provide the best compilation of evidence for this habitat, as described in the "Action Plan for the protection of the coralligenous and other calcareous bio-concretions in the Mediterranean". This data product contains large data gaps and should be viewed as incomplete.

  • 90th percentile Kinetic Energy due to waves at the seabed in the Mediterranean Sea and Black Sea in N m2/s - Created for the EMODnet Seabed Habitats broad-scale habitat map (EUSeaMap 2016). 90th percentile Kinetic Energy due to waves at the seabed in the Mediterranean Sea and Black Sea - Created for the EMODnet Seabed Habitats broad-scale habitat map (EUSeaMap 2016). This dataset is a raster composite of the outputs of several models, created for display in the EMODnet Seabed Habitats portal. The ISPRA Mc-WAF operational tool, designed to merge different scales for the generation and propagation of the wave energy, was used in the Mediterranean Sea (4km resolution) and the Adriatic Sea (1.6km), run for the years 2012-2015. In the Black sea the data was derived from the Kassandra project (variable resolution, years 2012-2014). Each dataset is available separately.

    Predictive Biological Zone layer produced by EMODnet Seabed Habitats as an input layer for the 2021 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.
