  • Seabed habitat map (EUNIS classification system) performed by Stareso within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Digital data sources: sonar (2010-2011), orthos (2010-2011), historical data (Guennoc et al., 2000; Pasqualini, 1997) Ground truth data sources (2008-2012): diving, sea-viewer Map confidence rated by Ifremer : 89%

  • Seabed habitat map (EUNIS classification system) performed by Andromede Oceanologie within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Digital data sources : Side scan sonar (2011), bathymetric datas (2009), orthophotos (2009, 2007) Ground truth data sources : Van Veen grab (2011), diver (2012), direct human observation (2012). Map confidence rated by Ifremer : 91% (Areas with doubtful classification and/or outlines are mentioned in the "VAL_COMM" field.

  • A biotope analysis of Dundrum bay was conducted in 2015 as part of efforts to understand the distribution and extent of benthic habitats and associated marine life within the Murlough special area of conservation incorporating new and historical groundtruthing information alongside modern acoustic data. The map was originally presented in the Marine Habitat Classification for Britain & Ireland (http://jncc.defra.gov.uk/MarineHabitatClassification). This has been translated to the EUNIS habitat classification system for integration with other European datasets. For more information, see: AFBI, 2015. Bathymetric and Habitat Map for Murlough Special Area of Conservation and offshore, Northern Ireland. Report to the Department of the Environment.

  • Seabed habitat map (Habitat Directive classification system) performed by Stareso within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Digital data sources: sonar (2010-2011), orthos (2010-2011), historical data (Cancemi et al., 2005; Pasqualini, 1997) Ground truth data sources (1996-2012): diving, sea-viewer, direct human observations, ROV Map confidence rated by Ifremer : 73%

  • Seabed habitat map (Habitat Directiveclassification system) performed by Andromede Oceanologie within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Digital data sources : Sonar (2012, 2010, 2007), bathymetric datas (2007-2010), orthophotos (2009), historical data (2007), GPS (04/2012, 06/2010).

  • 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. EUSeaMap, a European broad-scale seabed habitat map. Ifremer. http://doi.org/10.13155/49975

  • Seabed habitat map (EUNIS classification system) performed by Sintinelle within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Method used: supervised classification using ground truth data (2011-2012; diving, ROV, direct human observations, sea-viewer) and orthophotos (2010-04-08, 2009-08, 2007) and updating historical maps (2001, 1997). Map confidence rated by Ifremer : 82%
