Sea of Azov

The Sea of Azov is a unique inland shelf sea located in Eastern Europe.

It is connected to the much larger Black Sea by the narrow Kerch Strait. Because of this connection, it is often viewed as a northern extension of the Black Sea. The sea is bordered by Russia to the east. Ukraine occupies the northwest and southwest shores.

This location makes the sea a vital maritime route. It provides access to Central Asia via the Volga–Don Canal and the Caspian Sea.

This body of water is the shallowest sea in the entire world. Its depth is remarkably low, varying only between 2 and 14 meters.

The seafloor is relatively smooth and flat. This shape occurs because of a constant process of sedimentation. Large rivers, including the Don and the Kuban, flow into the sea. These rivers carry vast amounts of sand, silt, and shells into the water. As these materials settle, they form various bays, limans, and narrow spits.

The chemical makeup of the water is also quite distinct. Because so many freshwater rivers pour into it, the sea has low salinity. This means the water is not very salty compared to the open ocean. This low salt level, combined with high amounts of biomass, affects the water's color.

There is an abundance of plankton in these waters. This high concentration of microscopic life results in unusually high fish productivity.

The ecosystem supports many species, including large fish like the sturgeon.

Human history is deeply tied to these waters. In antiquity, the area was known as the Maeotis Swamp.

Ancient geographers often confused its extent due to strong currents. Some thought it was a massive lake, while others thought it was a swamp. The Maeotian people lived along its shores, practicing farming and fishing. They were also known as skilled warriors. In the 7th century BC, Greek colonization began in the region. This led to the establishment of the Bosporan Kingdom, which exported wheat and fish.

There are several theories regarding the name of the sea. One likely origin is the Kipchak Turkish word "azaq," meaning lowlands. This is linked to the settlement of Azov. Another Russian theory tells of a Cuman prince named Azum or Asuf. He was said to have died defending his town in 1067. The Ottoman Turks had their own name, calling it "Balük-Denis," or the "Fish Sea." This name reflected the incredible amount of fish found in the water.

The Sea of Azov has been a site of significant military conflict for centuries. In the late 17th century, Russia and Turkey fought for control. Peter I led Russian campaigns to capture the fortress of Azov.

He aimed to expand Russian naval access to the Black Sea. Later, during the Crimean War in 1855, British and French forces attacked the coast. They besieged Taganrog to disrupt Russian supply lines.

These conflicts show how strategically important the sea's coastline remains.

In the 21st century, the sea has become a point of intense geopolitical tension. Ukraine and Russia signed a treaty in 2003 to share the sea as internal waters. However, relations have become increasingly strained. In 2018, Russia seized three Ukrainian Navy vessels near the Kerch Strait. Control of the western shore is vital to the Ukrainian economy. It is also strategically important for Russia as a land route to Crimea. Following the 2022 Russian invasion of Ukraine, Russia captured the city of Mariupol. This gave them control over the entire north Pryazovia region, significantly altering access to the sea.
