Abstract

The paper considers the correlation between the variability of river discharges in the northwestern Black Sea and water salinity (from 1962 to 1994). As the most complete series, we have chosen salinity data collected at the port of Odessa. The dominant oscillations in the intra-annual variability of river discharges (Danube, Dniester, Dnieper, Yuzhny Bug) and salinity attain about 2–3 months and one year, respectively. In the inter-annual variability of river discharges and water salinity, cyclicities equal to about 4–6 months and 9–12 years, respectively, have been identified. Through analysing the inter-annual variations, an inversely proportional dependence has been found between the overall river discharges and salinity (between discharges in April and salinities in May, the correlation coefficient has amounted to −0.61). For each river, we have obtained the following dependences: for Odessa-Dniester, −0.72; and for Odessa-Danube, −0.65.
