The influence of river flow fluctuations on the distribution of chlorophyll in the estuarine zones of the Black Sea according to satellite observations
A statistical analysis was conducted on the variability of river runoff in the three largest rivers that flow into the northwestern part of the Black Sea - Danube, Dnieper, and Dniester. The study analyzed the influence of fluctuations in river flow on the distribution of chlorophyll-a in the Dniest...

Yu. Goncharov A.S. Tityapkin О.I. Shundel A statistical analysis was conducted on the variability of river runoff in the three largest rivers that flow into the northwestern part of the Black Sea - Danube, Dnieper, and Dniester. The study analyzed the influence of fluctuations in river flow on the distribution of chlorophyll-a in the Dniester and Dnieper-Bug estuaries, as well as in the areas affected by these rivers in different seasons. The analysis revealed that the distribution of chlorophyll in the sea is positively correlated with the flow rate, while in estuaries, a reduction in flow leads to an increase in chlorophyll concentrations. This is a negative factor that worsens water quality and increases the risk of ecological disasters associated with the eutrophication of water bodies. In the sea, the highest concentrations of chlorophyll in estuarine areas are observed in spring, with a gradual decrease until winter. Meanwhile, in estuaries, primary production processes reach their highest levels in summer. The Dnieper-Bug Estuary has the highest chlorophyll concentrations in all seasons and ranges of runoff. Проведено статистичний аналіз варіабельності річкового стоку трьох найбільших річок Чорного моря (Дунаю, Дніпра і Дністра), що впадають в північно-західну частину Чорного моря. Проаналізовано вплив коливань річкового стоку на розподіл полів хлорофілу в Дністровському та Дніпровсько-Бузькому лиманах та в зонах впливу річок у морі в різні сезони року. Зроблено висновок про те, що у морі зона розподілу хлорофілу позитивно залежить від величини стоку. У лиманах – навпаки, скорочення стоку призводить до збільшення концентрацій хлорофілу, що є негативним фактором, який призводить до погіршення якості води та до ризику екологічних катастроф, пов’язаних з евтрофікацією водойм. У морі найвищі концентрації хлорофілу в естуарних зонах спостерігаються навесні з подальшим поступовим зниженням до зими, у той час як у лиманах процеси первинної продукції фітопланктону сягають найвищого рівня влітку. Найвищі концентрації хлорофілу спостерігаються у Дніпровсько-Бузькому лимані в усі сезони року та періоди водності.
