Biodiversity on coastal boulders at Spitsbergen
Boulder communities were studied in summer 2002 in West Spitsbergen fiords. We examined multiple samples at three stations in Kongsfjorden (79° N, 12° E) and three stations in Hornsund (77° N, 16° E) fjord. Horsund is more influenced by Arctic water masses while Kongsfjorden is by Atlantic warmer wa...

Boulder communities were studied in summer 2002 in West Spitsbergen fiords.
