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...

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 species distributed from the Arctic to the warm-temperate region (25.9%). Four endemic Arctic species (Laminaria solidungula, Acrosiphonia flagellata, A. incurva, Urospora elongata) were found. Two species (Lithosiphon filiformis, Mikrosyphar polysiphoniae) were new for Svalbard. Chlorophyta, Phaeophyceae and Rhodophyta extended from the eulittoral zone down to 11, 21 and >30 m depths, with maximum biomasses at 1- 5 m, 5- 10 m and 5- 30 m depth, respectively.
