Evolution: Proceeding of the V International young scientists conference. - P. 33-34https://dspace.onu.edu.ua/handle/123456789/2487Timeliness of phytoplankton modern studies lies in integrated quality assessment of sea waters in the North-Western Black Sea. Peculiarity of the Island Zmiinyi’s coastal waters is periodic influence of sweetened Danubian waters’ hydrofront, which creates unique conditions for species diversity and development of certain /unique species and communities of phytoplankton. Aim of the work was to study changes happening in the species composition of phytoplankton depending on changes of hydrophysical and hydrochemical parameters of sea water: pH value, conductivity and nutrients concentration in the Zmiinyi Island coastal waters. Hydrological and hydrochemical observations and water sampling for determination of nutrients and phytoplankton were carried out on the research station «Zmiinyi Island» of Odessa National I.I.Mechnikov University in the framework of planned budgetary projects funded by the Ministry of education and science of Ukraine. The studies were based on the data from environmental monitoring carried out in 2010 on the permanent measuring station (“Pier”, depth 8 m).enZmiinyi IslandPhytoplanktonPhytoplankton Species DiversityNorth-Western Black SeaSpecies compositionArticle
