This thumbnail image focuses on the Sea of Azov and northern portion of the Black Sea, although the latter is visible in its entirety in the full image. The Sea of Azov is linked by the narrow (about 4 km) Strait of Kerch to the Black Sea to the south and is bounded in the north by mainland Ukraine, in the east by Russia, and in the west by the Ukraine’s Crimean Peninsula.
The Don and Kuban are the major rivers that flow into it. Visible to the northwest of the sea, in the upper left quadrant, is the Dnieper River. The large lake visible along the river is the Kakhovka Reservoir, covering a total surface area of 2,155 square kilometres in the territories of the Kherson, Zaporizhia, and the Dnipropetrovsk Oblasts of Ukraine.
