Seasonal Dynamics of Phytoplankton in the Chupa Inlet (Kandalaksha Bay, White Sea)

Seasonal Dynamics of Phytoplankton in the Chupa Inlet (Kandalaksha Bay, White Sea) After a long break since 1994, the dynamics of the structure and abundance of phytoplankton was studied again at different depths in the White Sea in March–November 2017. The microalgae abundance varied from 3.8 × 106 to 3519 × 106 cells/m3. Phytoplankton biomass ranged from 0.2 to 90 mg C/m3; it was the highest in the surface layer of the water column (0–5 m) with some exceptions. The algal abundance and biomass, integrated throughout the water column, varied from 0.2 × 109 to 68.5 × 109 cells/m2 and 0.01 to 1.38 g C/m2, respectively. Two peaks of phytoplankton biomass were identified, in early May after the ice melting and in early September. The summer peak of phytoplankton biomass, reported by previous studies in July in the surface layers, was not observed in 2017. This was caused by the dominance of smaller groups of nanoplanktonic prasinophytes, cryptophytes, and dinoflagellates. The change of dominant species may be related to the general tendency of decreasing the contribution of large species and increasing the share of heterotrophic taxa in the phytoplankton community due to more pronounced stratification of the water column caused by the climate warming. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Moscow University Biological Sciences Bulletin Springer Journals

Abstract

After a long break since 1994, the dynamics of the structure and abundance of phytoplankton was studied again at different depths in the White Sea in March–November 2017. The microalgae abundance varied from 3.8 × 106 to 3519 × 106 cells/m3. Phytoplankton biomass ranged from 0.2 to 90 mg C/m3; it was the highest in the surface layer of the water column (0–5 m) with some exceptions. The algal abundance and biomass, integrated throughout the water column, varied from 0.2 × 109 to 68.5 × 109 cells/m2 and 0.01 to 1.38 g C/m2, respectively. Two peaks of phytoplankton biomass were identified, in early May after the ice melting and in early September. The summer peak of phytoplankton biomass, reported by previous studies in July in the surface layers, was not observed in 2017. This was caused by the dominance of smaller groups of nanoplanktonic prasinophytes, cryptophytes, and dinoflagellates. The change of dominant species may be related to the general tendency of decreasing the contribution of large species and increasing the share of heterotrophic taxa in the phytoplankton community due to more pronounced stratification of the water column caused by the climate warming.
