title: Status of plankton algocenosis in the water area of the port of Tuapse and beyond it in the spring-summer period of 2019
abstract: The article presents the research of qualitative structure and quantitative development of phytoplankton in the water area of the port of Tuapse and beyond it in the spring-summer period of 2019. In April 2019, 43 phytoplankton species of 5 divisions were found. In the port area, the mean values of abundance and biomass were of 568 thousand cells·L−1 and 206 mg·m−3, respectively; in the open sea area, the values were 1.5 times higher. In the port area and beyond it, diatoms developed abundantly:
