Abstract

The results of the quantifying of inorganic nitrogen input to the Sevastopol Bay obtained by the analysis of atmospheric precipitation, selected on the marine hydro-meteorological station «Sevastopol» are discussed. The maximum and weighted average values of nitrogen concentration in 2016 was in 1,4 times more than in 2015. In the annual changes of the weighted average nitrogen concentration in 2015 – 2016 significant seasonal variation was not found. It is shown that the Redfield ratio may significantly shift towards inorganic nitrogen due to the flux of atmospheric precipitation on the Bay waters.
