Sea of Azov

The Sea of Azov (Russian: Азо́вское мо́ре, tr. Azovskoye more; Ukrainian: Азо́вське мо́ре, Azovs'ke more; Crimean Tatar: Azaq deñizi) is a sea in south-eastern Europe. To the south it is linked by the narrow (about 4 km or 2.5 mi) Strait of Kerch to the Black Sea, and it is sometimes regarded as a northern extension of the Black Sea. The sea is bounded in the north by mainland Ukraine, in the east by Russia, and in the west by the Crimean Peninsula. The Don and Kuban are the major rivers that flow into it. The Sea of Azov is the shallowest sea in the world, with the depth varying between 0.9 and 14 meters (2 ft 11 in and 45 ft 11 in). There is a constant outflow of water from the Sea of Azov to the Black Sea.

The sea is largely affected by the inflow of numerous rivers, which bring sand, silt, and shells, which in turn form numerous bays, limans, and narrow spits. Because of these deposits, the sea bottom is relatively smooth and flat with the depth gradually increasing toward the middle. Also, due to the river inflow, water in the sea has low salinity and a high amount of biomass (such as green algae) that affects the water colour. Abundant plankton results in unusually high fish productivity. The sea shores and spits are low; they are rich in vegetation and bird colonies.

History

Early settlements in the vicinity

The mouth of the Don River has always been an important commercial center. At the start of the 3rd century BCE, the Greeks from the Bosporan Kingdom founded a colony here, which they called Tanais (after the Greek name of the river). Several centuries later, in the last third of 1st century BCE, the settlement was burned down by king Polemon I of Pontus. The introduction of Greek colonists restored its prosperity, but the Goths practically annihilated it in the 3rd century. The site of ancient Tanais, now occupied by the khutor of Nedvigovka, has been excavated since the mid-19th century.

In the 5th century, the area was populated by Karadach's Akatziroi who came under the rule of Dengizich the Hun before Byzantium gave the land to the Hunugurs in the 460s to become known as Patria Onoguria under his brother Ernakh the Hun. The Kutrigur Hun inhabitants of Patria Onoguria became known as the Utigur Bulgars when it became part of the Western Turkic Kaghanate under Sandilch. Then in the 7th century Khan Kubrat ruler of the Unogundurs established Old Great Bolgary there before his heir Batbayan surrendered it to the Khazars.
