Kyrylenko N.F., Kushnir V.M., Lemeshko E.M.

The influence of the Danube and the Dnieper river run-off on the ecological situation of the North Western Black Sea shelf was studied on the basis of integrated studies. The following information was used for the analysis: a chlorophyll a concentration, vegetation index NDVI, brightness of normalized emergent radiation at various wavelengths, ocean surface temperature based on the data obtained from scanners, of the type SeaWiFS, MODIS, NOAA. Interrelation between the Danube and the Dnieper run-off and variability of a chlorophyll a concentration and index of the North Atlantic Oscillations (NAO) is revealed. It is shown that there is a well-marked interrelation between the hypoxia and index NDVI, and at the same time space of hypoxia can be evaluated on the basis of the relations from satellite data. The results obtained can be used for remote monitoring of the ecological conditions of the above-mentioned region.
