Swath area survey of the bottom in some sector (circle):
- obtaining acoustic image (AI) of the bottom and water column
- mosaic AI

Search for objects at the bottom and in the water column:
- detection and identification of objects by AI
- distance measurement by AI
- measurement of coordinates and dimensions of objects by AI
- determining the height of an object by its shadow on AI

Determination of the nature of the bottom relief and its inhomogeneities:
- assessment of relief by AI
- identification of the boundaries of inhomogeneities

Determination of depth at the point of standing:
- depth measurement by AI

The work is carried out due to the circular rotation of the SSS, located on a fixed carrier or when working on the ice through the hole.
