Sea of Azov

Background

The Sea of Azov is an inland shelf sea in Eastern Europe that is connected to the Black Sea by the narrow Strait of Kerch, which is about 4 kilometers wide at its narrowest point. It is generally 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, including areas of Ukraine that are currently under Russian occupation.

Geographically, the sea is shaped by the inflow of the Don, Kuban, and other rivers, which deposit sand, silt, and shells and create bays, limans, and narrow spits along its shores. These deposits leave the seabed relatively smooth and flat, with depth increasing gradually toward the center, while the low salinity and high biomass support abundant plankton and unusually high fish productivity. The Sea of Azov also serves as an important access route toward Central Asia through the Caspian Sea and the Volga–Don Canal, giving it economic and transport significance in broader regional connectivity.

Historically and strategically, the sea has mattered because it links river systems, coastal territories, and maritime access between Russia, Ukraine, and the Black Sea. Its shallow depth, low-lying shores, and narrow connection to the Black Sea have made it a distinct maritime space with both civilian and military relevance. Recent reporting in the database has also connected the area to infrastructure and reconstruction issues on the northern shore, including discussion of a ring road project and developments around the Donetsk People's Republic coastline.
