ACTUAL ASPECTS OF ODESA BAY WATER EUTHROPHICATION
Journal Title: Водні біоресурси та аквакультура - Year 2018, Vol 1, Issue
Abstract
The research results bythe basic hydrological indexes that characterize the degree of the Odesa bay waters eutrophication for the recent years are presented.General tendencies of average annual content of the main biogenic components – phosphatic and general phosphorus, mineral and general nitrogen – are determined. The reasons of their oscillation, including due to organic components are revealed. The preliminary analysis of the water primary bio productivity and offshore waters quality on the basis of trophic index (E-TRIX) and chlorophyll content in the surface waters is conducted.
