Broad-scale habitat map of the Atlantic waters - Scale 1:1,000,000

This layer is a predictive EUNIS seabed habitat map for the Atlantic area. The layer has been created using three pre-processed input datasets: substrate, biological zone and energy. The seabed substrate type layer is a compendium of historical maps. The biological zones layer was modeled thanks to layers of bathymetry, light attenuation, and wave wavelength. The layer of energy was prepared thanks to archived results of numerical models of waves and currents. The map follows the EUNIS 2007-11 classification system supplemented by additional categories in deep sea areas (Howell et al., 2010). The map does not include the intertidal zone. The study followed the methodology developped within the EUSeaMap project. For more details about the methodology see EUSeaMap final report (Cameron and Askew, 2011) or Coltman et al., 2008 For more details about the substrate and bathymetry that were used as a basis see Mata Chac├│n et al.
