It was performed within the framework of EMODnet Phase 2 Thematic Lot n┬░ 3 (aka EUSeaMap2). It is a preliminary version which will be refined during the course of the project. This layer was modelled with the use of base layers that were the bathymetry (Gebco_08) and the kdpar (bespoke computed layer) The biological zones boundaries were defined in the following way. - Infralittoral lower limit: limit at which the percentage of light reaching the seabed is 1%. The percentage of light layer was calculated by intersecting the kdpar and the bathymetry layers. For more details about this calculation see e.g. Cameron and Askew (2011). - Circalittoral lower limit: depth 80m - Deep circalittoral lower limit: depth 200m - Upper slope lower limit: depth 750m - Upper bathyal lower limit: depth 1100m - Mid bathyal lower limit: depth 1800m - Lower bathyal lower limit: depth 2700m Deep biological zones (from upper slope to abyssal) were chosen according to the classification proposed by Howell (2010).
