  • For each IHO Sea Area in the European Marine Waters (clipped), statistics on species occurrence where calculated. Each area displays the total number of observations. The attribute table contains also information on the individual observations and the occurrence of species per group (mammalia, aves, reptilia, benthos, zooplankton, phytoplankton, macroalgae and plantae). The statistics were calculated using the EurOBIS database, in 2011.

Digital data sources : Side scan sonar (2010), bathymetrics (2007), orthophotos (2006-2008), historical maps (2000-2011). Ground truth data sources (2010-2012) : Divers with underwater cameras, direct human observations. The accuracy of the mapping is heterogeneous according to the methods used (outlines by gps, field data, ...). The field "VAL_COM" specifies the uncertainty (doubtful classification and / or outlines). Overall confidence rated by Ifremer : 84%.
