FIELD: mining.
SUBSTANCE: surveying device comprises at least one exploratory cable (110, 111) each having a proximal end attached to the main vessel (100) and a distal end connected to at least one underwater towing vessel (130, 131), as well as at least one surveying device (120, 121) connected to the exploratory cable (110, 111) between its proximal and distal ends. During surveying, the survey cable (110, 111) extends in a direction perpendicular to the longitudinal axis (101) of the main vessel (100) a distance (E) sideways from the main vessel (100), for example under an ice cover such as hard ice or debris Ice.
EFFECT: increasing the expressiveness, informative and cost-effectiveness of exploration in the polar region, since the main ship only needs to break through a narrow channel in order to explore a large area, thus saving energy, time and money.
