The relief of the bottom of the Sea of Azov has in its structure the vast Accumulative Panov Plain, the deeper Zhelezinsky hollow and many braids and cans [1]. Basically, the bottom sediments of the central part of the sea are characterized by silts of various types, including clay. In the central part of the Taganrog Bay, bottom sediments also consist of silts. The braids of the Sea of Azov are mainly formed from various fractions of sand and shells. There are also extensive sand and shell fields around the spit, but for example, around the Long Spit, especially northeast of it, there is an extensive area of silty-silty sandstone. Under the influence of storms, in the process of material transfer, almost all the spit of the Sea of Azov gradually shifts in an easterly direction [2], while their western shores are eroded. And for the Long Spit, there is a process of intensive erosion of the eastern shore (2–3 m/year). The sediment areas in the area of the Sazalnitskaya Bank and the Sandy Islands are of particular interest. Monitoring the dynamics of such sediments is naturally important for navigation in the Taganrog Bay and in the sea as a whole.
