Investigations of Atmospheric Wet and Dry Nutrient Deposition to Marine Surface in Western Part of the Black Sea

The Black Sea ecosystem has three main sources of nutrient pollution: coastal, riverine and atmospheric inputs. Anthropogenically produced N transported to the coastal and open sea zones is closely connected with excess of nutrients supply that can result at acidification, eutrophication, excessive oxygen consumption and hypoxia. The aim of our work was to estimate the quantities and tendencies of atmospheric wet and dry depositions of nutrients (N and P) of different origin to the Zmiinyi Island surface during 2004 - 2010. Our study has confirmed previous findings that there was practically no N and P emission over the open sea and the main source of transportation (91-99% of NH4+, NO3- and PO43-) was atmospheric runoff from the continent. We have shown that aerosol removing over the sea occurs for the most part by means of dry deposition (40-80% of bulk deposition). We have assessed that in 2004 - 2010 average annual atmospheric bulk depositions of inorganic N and P made 694±45 kg N km-2 (in the form of NH4+, NO3- and NO2-) and 100±11 kg P km (in the form of PO43-). Important direction was the study of organic N in bulk deposition, which exceeds mineral N part about 1.6 times.
