Map of surface sediments in the Bulgarian Black Sea shelf classified according Folk 7-coarse sediment, mixed sediment , sand , sandy mud,mud, muddy sand,rocks
Map of surface sediments in the Bulgarian Black Sea shelf classified according Folk 5-coarse sediment, mixed sediment , sand and mud , muddy sand, rocks
Map of broad habitat types in Bulgarian Black Sea shelf which equate to one or more habitat types of the EUNIS classification
A composite Habitats Directive Annex I feature extent map of Submarine structures made by leaking gases for the Croker Carbonate Slabs cSAC/SCI was created by JNCC staff to provide the most up-to-date knowledge of MDAC coverage within the site. Existing polygon data from three previous surveys (CEND1108, CEND0513 and CEND2315) and habitat maps were combined with groundtruthing point information, to build a composite understanding of “High” and “Potential” Annex I feature within the site.
Confidence in the classification of substrate type in the 2019 EUSeaMap broad-scale predictive habitat map. Values are on a range from 1 (Low confidence) to 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. Detailed information on the modelling process for the 2016 is found in section 2.7.2 of the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version. Created by the EMODnet Seabed Habitats project consortium.
Seabed habitat map (current EUNIS classification system and submission) performed by CREOCEAN, LIENSs, EPOC, GEOTRANSFERT, RE NATURE ENVIRONNEMENT & IODDE within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). This map concerns polygons for which at least one habitat IS NOT in the current EUNIS classification (2007-2011). Digital data sources: orthos (2000), prefectural decrees Ground truth data sources (2011-2012): direct human observations Map confidence rated by Ifremer : 89%
Confidence in the classification of salinity regime in the EUSeaMap (2019) broad-scale predictive habitat map. Values are on a range from 1 (Low confidence) to 3 (High confidence). Salinity regime is one of the layers of information used to categorise physical habitat types in the Baltic Sea area of EUSeaMap; these layers of information are collectively known as 'habitat descriptors'. Confidence in the classification of salinity regime 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 salinity regime. Created by the EMODnet Seabed Habitats project consortium.
Broadscale habitat (EUNIS level 3) for Land's End (Runnels Stone) recommended Marine Conservation Zone (rMCZ) Updated habitat map resulting from an intergrated analysis of the acoustic and ground-truth survey data from 2013 (onboard the Coastal Survey Vessel (CSV) Water Guardian on cruise wgdn0112). Sediment types at each groundtruthing station were used to inform a semi-automated process of map production using object-based image analysis (OBIA).
Broadscale habitat (EUNIS level 3) for the Goodwin Sands recommended Marine Conservation Zone (rMCZ).Seabed texture polygons mapped using semi automated ISO cluster unsupervised classification and expert interpretation of acoustic data (MBES bathymetry and backscatter) and groundtruthing data from PSA analysis and image (stills and video) classification.
Confidence in the 2016 EUSeaMap salinity regime class in the Baltic Sea and Kattegat strait in the North Sea/Baltic Sea, 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 salinity regime are driven by the confidence in the salinity data used to determine the descriptor, and the confidence in the threshold/margin between classes (areas closer to a boundary between two classes will have lower confidence).
