| Abstract: | Forty-two mesozooplankton samples were collected in the Barents Sea during the cruise of the R/V Dal’nie Zelentsy in August 2006. In total, 72 taxa of planktic animals were found. The minimal average mesozooplankton abundance was noted
in the Murmansk coastal waters in the south of the sea (154 ind./m3), while the maximal was noted in the Arctic waters (1533 ind./m3). The average wet biomass varied from 32 to 830 mg/m3. The zooplankton abundance and biomass exceeded the relevant average long-term parameters by 1.5–2 times and by 1.2–1.4 times,
respectively. The mean biodiversity (Shannon’s index) of the zooplankton communities was low: H′ = 1.62 ± 0.104 bit/ind. |
