Based on the Brotskaya and Zenkevich (1939) investigation, six main bottom community areas within the open part of the Barents Sea was defined. The south western Barents Sea (I, red area in figure 2.4.11) was characterized by its high abundance of boreal species and predominance of seston-feeders in biomass, whereas the central Barents Sea (II, light blue area in figure 4), at an average depth about 200m and on sandy silt, has a rather low biomass compared to other communities in the Barents Sea.
