Abstract
Biological zone maps have been prepared for each basin of the EUSeaMap study area by integrating bathymetry with information about light attenuation through the water column (all basins), wave attenuation through the water column (North Sea and Celtic Seas), the position of the deep halocline (Baltic), manual interpretations of slope values and bathymetry (Western Mediterranean), and information about depth zonation in deep sea communities (North Sea and Celtic Seas).
BIOLOGICAL ZONES OF THE BALTIC SEA: Infralittoral: 0m - 1.6 ratio of depth:Secchi depth for oligohaline OR 2.5 ratio of depth:Secchi depth for mesohaline Upper circalittoral: 1.6 ratio of depth:Secchi depth and deeper for oligohaline (deepest zone) OR 2.5 ratio of depth:Secchi depth - Position of deep halocline for mesohaline Deep circalittoral: Position of deep halocline and deeper for mesohaline (deepest zone)
