Certain aspects of the present disclosure generally relate to cleaning geophysical equipment in water. An exemplary method includes illuminating, with laser light, an obstruction on the geophysical equipment while the geophysical equipment is deployed in an operable configuration (e.g., towed by a survey vessel).

Biofouling target removal

Techniques are disclosed relating to geophysical surveying. In some embodiments, an added unique fold parameter is determined for one or more bins during a survey of a geophysical formation. In some embodiments, the position of one or more elements of a survey system is adjusted based on the added unique fold. In some embodiments, a ratio of the determined added unique fold to a theoretically obtainable added unique fold is determined, and the adjustment may be based on this ratio. In some embodiments, an acceptability parameter is also considered. In some embodiments, survey elements may be steered to increase added unique fold without leaving coverage holes that violate an acceptability criterion. In some embodiments, the steering is performed automatically. In some embodiments, coverage parameters are graphically displayed to an operator.
