Contribution of Atmospheric Depositions to Inventory of Nutrients in the Coastal Waters of Crimea

Coastal zones are extremely vulnerable and, at the same time, anthropogenically pressed. Excessive enrichment of marine waters with nutrients and organic matter can lead to “red tides”, oxygen deficits, decreasing assimilation capacity, etc. The purpose this work is study atmospheric precipitations as a source directly affecting coastal areas Crimea ultimately, strengthening eutrophication consequences. In 2004–2008, from 2015 present, samples have been collected Marine Hydrometeorological Station in Sevastopol. They analyzed for content inorganic nitrogen, phosphorus, silica. For 2009–2014, direct measurements unavailable previously retrieved multiple nonlinear regression equation has used estimate concentration nitrogen depending on meteorological conditions, including number precipitations, days without relative air humidity, wind direction vectors, temperature. Data obtained revealed that one important inputs local areas. Their contribution increases time scale days, while role rivers remains most annual scale. inventory becomes more significant summer, when seasonal stratification water column prevents vertical mixing waters, ambient upper layer minimal.
