Species composition, zonation, and biomass of marine benthic macroalgae in Kongsfjorden, Svalbard

Macroalgae in Kongsfjorden were surveyed by divers down to 30 m depth at Hansneset, Blomstrand (78° 39’N, 11°57’E). In total, 62 species were identified, 16 Chlorophyta, 25 Phaeophyceae and 21 Rhodophyta. The majority of species (53.5%) belonged to the Arctic cold-temperate group, followed by specie...
