Abstract
The results of evaluation of the dissolved inorganic nitrogen (nitrate, nitrite and ammonium), dissolved inorganic phosphorus (phosphate) and silicon fluxes to the region of Katsiveli (Southern coast of the Crimea) supplied via atmospheric precipitations in 2010–2015 are discussed in this paper; their seasonal and inter-annual changes are also studied. The obtained data indicated that the main forms of nitrogen in atmospheric depositions are nitrates and ammonium. The increase of nutrients content in warm period of the year in intra-annual change is observed for all elements. It can be explained both by inverse dependence of elements concentration on precipitation amount and by features of their migration and input sources. It has been also revealed that the six-year average flux of the nutrients consists of 30.4 mmol/m2∙year of inorganic nitrogen and 0.118 and 0.315 mmol/m2∙year of phosphorus and silicon, respectively. It has been noted that atmospheric deposition of inorganic nitrogen can lead to increase of primary production in the Black Sea on to 2.5%, while annual inorganic phosphorus input with atmospheric depositions contribution to primary production formation makes up 0.5 %. Additional contribution of inorganic silicon atmospheric input to primary production formation made up 0.02 % of its annual value in the Black Sea open part.
