Purpose of the work was to quantify riverine nitrogen (N) and phosphorus (P) loads to the Dniester Estuary and estimate their contributions to the Black Sea over 2010-2019. Methodology. The data on monthly water discharge and monthly N and P compounds concentrations in surface water monitored in-situ were used. Results and Discussion. Mean annual riverine water discharge to the estuary was 7.9ffi0.2 km³ (range: 5.6-14.2 km³). Higher variation of water discharges was found in the Turunchuk River (variation coefficient of 38%), 1.7 times higher than in the Dniester River before confluence. Annual TN loads to the estuary varied from 10.8 GgN (2016) to 74.6 GgN (2010), the mean was 25.7ffi5.8 GgN/year. Mean annual TP load was of 1.16ffi0.08 GgP/year (range: 0.95-1.66 GgP/year). On average, the shares of organic N and P were 48% and 43% respectively. Nitrates dominated in DIN contributing 84ffi2%. Conclusions. Dniester water discharge and thus water supply for its deltaic area are strongly dependent on climatic and anthropogenic factors, both affected by climate change. We have found that 25.7ffi5.8 GgN/year and 1.16ffi0.08 GgP/year are entering the Dniester Estuary annually. Mean riverine total N and total P loads to the Black Sea made 23.1ffi5.2 GgN/year and 1.04ffi0.07 GgP/year.
