Abstract: | Abundance and biomass of pico- (<2 μm) and nanoplankton (2–20 μm) were investigated in relation to hydrography in Kongsfjorden,
Svalbard (79°N, 12°E) during late summer 2006. Autotrophic and heterotrophic picoplankton abundance ranged from 0.1 × 106 to 35.2 × 106 cells L−1 and from 0.4 × 106 to 20.3 × 106 cells L−1, respectively. The highest number of bacteria in the entire water column was recorded at station 2 at 10 m (22.3 × 108 cells L−1); the lowest concentration was observed at station 1 (6.0 × 108 cells L−1). The abundance of autotrophic and heterotrophic nanoplankton varied from 0.4 × 105 cells L−1 to 46 × 105 cells L−1 and from 0.3 × 106 to 9.1 × 106 cells L−1, respectively. Our results demonstrated that heterotrophic nanoflagellates and bacteria in Kongsfjorden microbial community
were relatively important. The structure of plankton communities integrated with environmental variables could act as indicators
of the variability of the inflow of Atlantic Water into Kongsfjorden. |
