biological zones of the EU's Atlantic Area
This layer is a model of the biological zones of the EU's 'Atlantic Area 2007-2013'. It was performed within the framework of MeshAtlantic project (INTERREG ÔÇÿAtlantic Area 2007-2013ÔÇÖ program).
This layer was modelled with the use of bespoke base layers that were the bathymetry, wave wavelength and the kdpar
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. Vasquez et al. (in press).
- Circalittoral lower limit: limit at which the ratio wave wave length over the depth equals 2.53
- Deep circalittoral lower limit: break of slope due to the entrance into the continental slope. This limit was digitalized with the use of the bathymetry layer
- Upper slope lower limit: depth 750m
- Upper bathyal lower limit: depth 1100m
- Mid bathyal lower limit: depth 1800m
- Lower bathyal lower limit: break of slope due to the entrance into the abyssal plain. This limit was digitalized with the use of the bathymetry layer
Deep biological zones (from upper slope to abyssal) were chosen according to the classification proposed by Howell (2010).
