Seasonal dynamics of nitrogen-containing substances in the Black Sea coastal zone by example Gelendzhik and Golubaya bay

Abstract

In the course of studies of hydrochemical monitoring data for the period from 2017 to 2019, we found that the Gelendzhik bay, which belongs to semi-closed water areas, has an increased background of mineral and organic nitrogen forms compared to the background in the Golubaya bay corresponding to the open coast. Increased concentrations of mineral forms of nitrogen in the Gelendzhik bay we detected, probably due to anthropogenic impact.
