The map of the trophic state of water in the Danube Delta

Summary[edit]

Description
Українська: Карта трофічного стану води в районі дельти Дунаю отримана 8 листопада 2020 року на основі скриптуSe2WaQ реалізованому в EO-browser. Градієнтне зображення трофності створено з веб-інструменту з відкритим кодом для перегляду, візуалізації та аналізу супутникових зображень EO-browser створеного в рамках проекту Copernicus. Сценарій Se2WaQ - Sentinel-2 Water Quality розроблений N S A Pereira - використовує знімки Sentinel-2 (L1C та L2A) для визначення трофічного стану водойм на основі шести відповідних показників якості води: концентрація хлорофілу a, щільність ціанобактерій, каламутності, забарвлена розчинена органічна речовина, розчинений органічний вуглець і колір води. На карті видно, що вода яку виносить річка Дельта при впадінні в Чорне море дуже відрізняється за своїм трофічним станом, що може бути пов’язано з відповідним антропогенним впливом.
English: The map of the trophic state of water in the Danube Delta region was obtained on November 8, 2020 on the basis of the Se2WaQ script implemented in the EO-browser. The trophy gradient image is created from an open source web tool for viewing, visualizing and analyzing satellite images of the EO-browser created within the Copernicus project. The Se2WaQ scenario - Sentinel-2 Water Quality developed by NSA Pereira - uses Sentinel-2 products (L1C and L2A) to determine the trophic status of water bodies based on six relevant indicators of water quality: the concentration of Chlorophyll a, the density of cyanobacteria, turbidity, colored dissolved organic matter, dissolved organic carbon and water color. The map shows that the water carried by the Delta River at the confluence with the Black Sea is very different in its trophic state, which may be due to the corresponding anthropogenic impact.
