Paper Abstract

On the basis of daily means of sea surface temperature, concentration of chlorophyll "a", diffuse attenuation coefficient Kd(490) and remote sensing reflectance Rrs(555) from the array of satellite measurements with high spatial resolution COPERNICUS spatial-temporal features of seasonal and inter-annual variability of these parameters on the Black Sea surface analyzed. Shown, that in 2017, the main maximums of the Chl-a concentration and the coefficients of diffuse attenuation Kd(490) were observed in November-December. The second maximum of Chl-a and Kd(490) in the northern coastal zone of the sea was observed from February to June, in the in the deep sea – from February to March, near the sea southern coasts – from February to April. The main maximum of remote sensing reflectance Rrs(555) was observed in June-July. Shown, that in 2017 the sea surface temperature was higher than the climatic norm, the largest anomalies were observed mainly on the northwestern shelf and in the zone of the Eastern large-scale cyclonic gyre. Anomalies of Chl-a and Kd(490) during the year were predominantly negative, and the appearance of positive anomalies was observed in April to the west and to the east from the Crimean coasts. The Rrs(555) values for almost the whole year were close to the climatic norm except for June, when they were several times higher than climatic values.
