Increasing navigation rates have resulted in more pollution and even in ecological disasters. On 11 November 2007, a strong storm sank four ships in the Kerch Strait, in the Russian Port of Kavkaz. The ships were the Russian bulk carriers Volnogorsk; Nakhichevan; and Kovel, and the Georgian Haji Izmail with a Turkish crew. Six other ships were driven from their anchors and grounded. The tanker was broken in two, and the tanker Volgoneft-123 was damaged. As a result, about 1,300 tons of fuel oil and about 6,800 tons of sulfur entered the sea.
