In the tidal zone, small brown, green and red algal species dominate the flora. In the subtidal region, large kelp species such as sugar kelp {Saccharinalatissima) and tangle kelp (Laminaria hyperborean) grow dense underwater forests with canopy-like structures (Christie et al., In bays and inlets, eelgrass (Zostera marina) often dominate on sandy/muddy sediments and form extensive meadows (Bekkby et al., In the open water masses along the coast and in the offshore pelagic zone, microalgal species are the dominant primary producers (e.g. Skeletonema, Thalassiosira, Chaetoceros spp.).
