SPATIAL HETEROGENEITY OF CHLOROPHYLL <i>a</i> CONTENT IN NOVOSIBIRSK RESERVOIR
Spatial heterogeneity of phytoplankton chlorophyll a in the Novosibirsk reservoir in summer was analyzed based on the long-term studies (2007-2018). Vertical and horizontal distribution of phytoplankton chlorophyll a in different parts of the reservoir was identified. Along with very weak inter-annual fluctuations, its concentrations were the lowest in the middle part. The highest content of chlorophyll a is typical for deep-water sections of the river part. The Berd Bay is distinguished by the highest average long-term concentration of pigment among the bays of the reservoir. The Novosibirsk reservoir is eutrophic according to the most frequent values of summer chlorophyll concentrations.
