| Abstract |
The effect of nitrogen and phosphorus additives on the species structure of the natural phytoplankton population at the end of May 2019 was studied. An increase in the concentration of nitrogen and phosphorus in seawater led to a rise in the number of coccolithophores, while the relative contribution of phosphorus was higher. The predominance of small-cell diatoms in the community was facilitated by the simultaneous addition of nitrogen and phosphorus. In contrast, the relative contribution of nitrogen was higher than that of phosphorus. An increase in nitrogen concentrations at relatively low phosphorus concentrations intensified the growth of large-cell diatoms. |
