Abstract The main objective of this work was to investigate the temporal variability hydrochemical parameters in two coastal regions Northeastern Black Sea: Gelendzhik bay, influenced by anthropogenic activities and Golubaya bay an open region. Dissolved oxygen, biochemical oxygen demand, pH, alkalinity, phosphate, organic phosphorus, silicates, nitrates, nitrites, ammonia, nitrogen, oil products heavy metals were measured. Si/P Si/N ratios showed that waters significantly enriched nitrogen...
The results of long-term oceanological studies that were carried out as part the Black Sea 2017–2021 complex scientific expedition and are devoted to study coastal zone sea based on monitoring observations presented. During all five years, a stable trend decrease in content silicon active layer coastal-shelf was observed. last 3 there has been an increase reserves mineral phosphorus nitrogen. As result this variability phosphorus, nitrogen silicon, during 2021, such stoichiometric...
In the course of studies hydrochemical monitoring data for period from 2017 to 2019, we found that Gelendzhik bay, which belongs semi-closed water areas, has an increased background mineral and organic nitrogen forms compared in Golubaya bay corresponding open coast. Increased concentrations detected, probably due anthropogenic impact.
