The Kerch Strait
The Kerch Strait connects the Black Sea and the Sea of Azov. It separates the Kerch Peninsula in eastern Crimea from the Taman peninsula in western Russia.
The strait is 4.5 to 15 km (3-11 mi) wide and up to 18 meters deep. The most important harbor is the city of Kerch, in Crimea.
An algal bloom can be seen along both the Russian and Crimean shorelines. Some of the lakes just inland on the Russian side also appear very green with algae.
The brown area along the Russian shoreline is swampland or wetlands, not used for agriculture unlike much of the surrounding area.
