Azov Sea
The Sea of Azov is an inland shelf sea in Eastern Europe connected to the Black Sea by the narrow (about ) Strait of Kerch, and sometimes regarded as a northern extension of the Black Sea. The sea is bounded by Russia on the east, and by Ukraine on the northwest and southwest (the parts of Ukraine bordering the sea are currently under Russian occupation). It is an important access route for Central Asia, from the Caspian Sea via the Volga–Don Canal. The sea is largely affected by the inflow of the Don, Kuban, and other 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. Because of 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 result in unusually high fish productivity. The sea shores and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
