Long-term variations in the biogenic matter runoff of the Dnestr River

Long-term observation data were used to carry out comparative analysis of variations in the biogenic matter runoff of the Dnestr River over a period of fifty years. Based on data of weekly monitoring in 2002-2004, annual dynamics of biogenic matter runoff was analyzed for the Dnestr River and for Dn...

Description
Summary:Long-term observation data were used to carry out comparative analysis of variations in the biogenic matter runoff of the Dnestr River over a period of fifty years. Based on data of weekly monitoring in 2002-2004, annual dynamics of biogenic matter runoff was analyzed for the Dnestr River and for Dnestr Liman. It was found out that, in spite of the “buffer” role of the latter, the contribution of biogenic substances, finding their way in the sea with the Dnestr River water, to the eutrophication of the northwestern Black Sea remains appreciable (about 60 thousand ton year⁻¹). Dissolved organic compounds account for 70% of the present-day biogenic matter runoff of the Dnestr River.
