  • Confidence in the classification of oxygen regime in the EUSeaMap (2019) broad-scale predictive habitat map. Values are on a range from 1 (Low confidence) to 3 (High confidence). Oxygen regime is one of the layers of information used to categorise physical habitat types in the Black Sea area of 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 oxygen regime. Created by the EMODnet Seabed Habitats project consortium.

  • Confidence in the below halocline probability layer, produced by DHI, for the EUSeaMap 2019 broad-scale habitat model. Values are on a range from 1 (Low confidence) to 3 (High confidence). Salinity data acquired from DHI hydrographic Model MIKE III (3D baroclinic model for free surface flow), with a resolution of a 5.5 km. Detailed information is found in the EMODnet Seabed Habitats technical report: Populus J. et al 2017. EUSeaMap, a European broad-scale seabed habitat map. Ifremer. http://doi.org/10.13155/49975

  • Confidence in kinetic energy due to currents values, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps. Values are on a range from 1 (Low confidence) to 3 (High confidence). Detailed information on the confidence assessment in Populus J. et al 2017. EUSeaMap, a European broad-scale seabed habitat map.

  • Confidence in the PAR at seabed values, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps. Values are on a range from 1 (Low confidence) to 3 (High confidence). Confidence in Photosynthetically Active Radiation (PAR) at the seabed are driven by the confidence in the underlying data used to determine the descriptor (PAR at the surface, light attenuation coefficient KD(PAR) and depth to the seabed.) and the confidence in the threshold/margin between classes (areas closer to a boundary between two classes will have lower confidence).

  • Areas of high riverine inputs for EUSeaMap 2016 Biological zone model. The map cover the Adriatic Sea(Po river plume), east Mediterranean (Thessaloniki gulf and bay, the Maliakos gulf, and Geras gulf in the Aegean Sea) and the Black Sea (Dnieper-Bug river plume area). These are were handled separately in the EUSeaMap 2016 modelling process. This layer is one of several habitat descriptors used to model biological zone and habitat class. To establish the limit of these areas datasets on salinity and water temperature were used, where possible. Detailed information available in Section 2 of: Populus J. et al 2017.

  • Predictive Biological Zone layer produced by EMODnet Seabed Habitats as an input layer for the 2016 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 Norway 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 Arc Model Builder (10.1). The model was created using raster input layers with a cell size of 0.002dd (roughly 250 meters). The model includes the sublittoral zone only (Infralittoral to Abyssal zone). For details on methodology see: Populus J. And Vasquez M. (Eds), 2017.

  • Confidence in kinetic energy due to current values, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps. Values are on a range from 1 (Low confidence) to 3 (High confidence). The confidence assessment considered factors such as: • Quality of training data and methods used to construct the model. • Temporal resolution. • Spatial resolution Detailed information on the confidence assessment in Populus J. et al 2017.

  • Oxygen regime class layer in the Black Sea produced by EMODnet Seabed Habitats as an input layer for the 2016 EUSeaMap broad-scale habitat model. The map of oxygen regime classes was produced using underlying potential density anomaly at the seabed and thresholds derived from statistical analyses or expert judgement on known conditions. Detailed information on the modelling process is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources).

  • Confidence in the depth to seabed, produced by EMODnet Seabed Habitats for the 2016 EUSeaMap broad-scale predictive habitat maps. Values are on a range from 1 (Low confidence) to 3 (High confidence). The EMODnet Bathymetry project was the source of the depth to the seabed dataset (a digital elevation model (DEM). The project also produced a ‘quality indicator’ based on data relative age, relative sampling effort and number of soundings. The quality indicator scores were categorised into "high", "moderate" and "low" confidence. Detailed information on the confidence assessment is in Populus J. et al 2017.

  • Classified seabed substrate types (Polygon layer) for European seas. Produced by EMODnet Seabed Habitats as an input layer for the 2016 EUSeaMap broad-scale habitat model and re-used for EUSeaMap 2019, based on EMODnet Geology seabed substrate products. 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 Norway in the North. The layer of seabed substrate was produced using data from EMODnet geology 1:250.000 and 1:1M seabed substrate maps, and integrated with extra substrate feature relevant for habitat mapping (seagrass beds, for example). The Folk 5 classification of substrate is adopted because it is compatible with the EUNIS classification of habitats used in EUSeaMap 2016.
