Undersøkelser av stortarehøsting i Nordland i 2014
The Institute of Marine Research surveyed the kelp vegetation, before and after kelp (Laminaria hyperborea) harvesting in southern parts of Nordland county in 2013 and 2014. Survey stations included both kelp harvested areas and nearby reference areas, and was performed by underwater video. In addit...
