The Zmiinyi Island which is located 40 km far from the Danube Delta is one of such reference areas, as anthropogenic influence in its coastal waters is minimal. The aim of the research was to study the structure of phytoplankton community, especially HTMP and Cyanobacteria, in the coastal waters of the Zmiinyi Island during 2012–2014.enZmiinyi IslandphytoplanktonHarmful speciesBacillariophytaDynophytaArticle
