Описание: Satellite: Sentinel-2. Sensor: MSI (MultiSpectral Instrument). Visualization RGB: bands 4 (red), 3 (green), 2 (blue). True color. La imagen tiene 95 km de ancho (aprox.) Vista parcial del delta del r'io Volga en el mar Caspio, parcialmente congelado, a principios del mes de marzo. The upper and middle courses of the Volga begin to freeze at the end of November, the lower reaches in December. The ice breaks up at Astrakhan in mid-March, at Kamyshin at the beginning of April, and everywhere else in mid-April. The Volga is generally free of ice for about 200 days each year and for about 260 days near Astrakhan. As great masses of water accumulated within the reservoirs constructed during the Soviet period, however, the temperature regime of the Volga was so changed that the duration of ice increased on the headwaters of the reservoirs and decreased on the stretches below the dams.
