Abstrakt: The task of targeted sampling of sediments in the immediate vicinity of objects presumed to be sources of chemical pollution of the sea has been solved. A cassette sampler with six grabs was built, which is constantly controlled by cable under video surveillance. The device is operated from a light boat, which can be kept in place over the object and moved in a preset direction. Positioning at the moment of sampling is carried out by fixing the coordinates of the boat by GPS/GLONASS. The efficiency of the developed sampling system is proved by successful use of the device in surveying a number of potentially hazardous underwater objects found in chemical weapons disposal areas in the Baltic Sea.
