Pre-project documentation for carrying out engineering-geological, geophysical, hydrographic work must be accompanied by a profile soil section of the bottom soil in the area of the work being carried out. It is possible to remotely obtain a profile section of the bottom soil using a single-beam acoustic profiler of the bottom soil, but the information sought is point-by-point in nature due to the narrow swath of the bottom survey, and the process of soil survey requires large time and material costs. To remotely obtain a larger volume of continuous information (in a larger swath) about the structure of the bottom soil along the line of movement of the carrier vessel, it is necessary to use a multi-beam acoustic profiler, which makes it possible to significantly increase the productivity of the profiling process, which will reduce time and financial costs.

The use of a multi-beam acoustic profiler of bottom soil will make it possible to abandon traditional single-beam acoustic profiling systems, which will significantly increase the productivity of soil surveys and reduce the time and financial costs of studying bottom sedimentary structures.
