Comparative Assessment of Coastal Marine Waters Quality in the Odessa Bay And in The Zmiinyi Island Area in 2016
Abstract
Purpose. To reveal peculiarities of marine environment quality on the results of simultaneous observations in marine waters of two Black Sea areas with different levels of anthropogenic pressure. Мethods. Hydrological and hydrochemical and hydrobiological studies. Results. Based on the results of comprehensive studies performed from April to December 2016 in two regions with different anthropogenic pressure calculations of the index of marine waters trophic status TRIX were made. The analysis of the TRIX changes dynamics has shown that its seasonal variations are observed in both areas, as well as seasonal variations of practically all physicochemical characteristics of aquatic environment. Conclusions. It has been shown that the trophic status of water in Odessa Bay is higher than in the Zmiinyi Island area, i.e. the quality of aquatic environment in Odessa Bay is lower than in the Zmiinyi Island coastal waters. At that, degradation of water quality was registered as compared to the period of 2004-2013.
