It is connected to the Black Sea through the narrow Strait of Kerch. The sea is bordered by Russia and Ukraine which makes it an important maritime and geopolitical region. It is globally recognized as the shallowest sea, with unique hydrology, low salinity, high biological productivity and significant historical, economic and strategic importance.<\/span><\/p>\n<h2><b>Sea of Azov Features<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The Sea of Azov shows unique physical, geological and historical characteristics shaped by rivers, shallow depth and continental climate influences.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Location<\/strong>: Situated in Eastern Europe, it lies north of the Black Sea and connects through the Strait of Kerch, about 4 km wide, forming part of a larger marine system linking to the Mediterranean.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Size<\/strong>: The sea is about 360 km long and 180 km wide, covering nearly 39,000 sq km, making it the smallest sea in the former Soviet region.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Depth<\/strong>: It is the shallowest sea globally with an average depth of 7 metres and maximum depth of 14 metres, with flat seabed gradually deepening toward the centre.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Common Names<\/strong>: Historically called Maeotis Swamp, Lake Maeotis and Temarunda meaning \u201cMother of Waters\u201d, while Ottoman Turks referred to it as Bal\u00fck-Denis or \u201cFish Sea\u201d.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Geological Formation<\/strong>: Large sediment inflow from rivers deposits sand, silt and shells, forming a smooth seabed, numerous sandbanks, limans and long spits like Arabat Spit.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Major Rivers<\/strong>: The Don and Kuban rivers contribute over 90% of freshwater inflow, reducing salinity and bringing nutrients, along with smaller rivers like Mius, Kalmius and Berda, which form <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/estuary-ecosystem\/\" target=\"_blank\"><strong>estuaries<\/strong><\/a> on merging.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Salinity Characteristics<\/strong>: The sea has low salinity (10-12 PSS), much lower than oceans and becomes almost fresh in regions like Taganrog Bay due to river inflow.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Coastal Features<\/strong>: The coastline is low and flat with extensive vegetation, <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/lagoon-formation\/\"

style=\"font-weight: 400;\"><strong>Climate Conditions<\/strong>: It has a continental climate with cold winters (-1 to -5\u00b0C, sometimes -30\u00b0C) and warm summers (23-25\u00b0C), with frequent storms and seasonal ice formation.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Historical Importance<\/strong>: It has been a centre of Greek colonisation, Bosporan Kingdom trade, Russo-Turkish conflicts, Crimean War operations and modern geopolitical developments.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Navigation and Connectivity<\/strong>: It connects Central Asia to global markets via the Volga-Don Canal, linking major river systems and enabling inland water transport.<\/span><\/li>\n<\/ul>\n<h2><b>Sea of Azov relation with Russia and Ukraine War<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">The Sea of Azov has become a major geopolitical hotspot due to its control, military activity and economic importance in recent conflicts.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Shared Waters Agreement<\/strong>: In 2003, Russia and Ukraine agreed to treat the sea and Kerch Strait as shared internal waters, allowing free navigation and joint usage.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Strategic Military Build up<\/strong>: Since 2018, both countries increased naval presence, with Ukraine
