Don River Spilling Sediments into Sea of Azov47.0N 39.4E
The Sea of Azov is the shallowest sea in the world with an average depth of 13 metres (43 ft) and maximum depth of 15.3 metres (50 ft).
In places where silt has built up, such as Taganrog Bay (above, center), the average depth is less than 1 metre (3 ft). Here, sediments from the Don River (top right quadrant) can be seen spilling into the bay, coloring its waters green, and gradually swirling downwards into the rest of the sea.
The prevailing current in the sea is a counter-clockwise swirl. Salinity varies from 1 to 15 parts per thousand (compared to 30 to 40 for the oceans) across the sea and with season.
The Strait of Kerch links the Sea of Azov to the Black Sea (below).
