Abstract: 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.

Abstract: 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).

Abstract translation: 公开了与地球物理测量有关的技术。 在一些实施例中，在地球物理地层的测量期间，为一个或多个箱确定添加的独特折叠参数。 在一些实施例中，基于添加的唯一折叠来调整测量系统的一个或多个元件的位置。 在一些实施例中，确定所确定的添加的唯一折叠与理论上可获得的添加的唯一折叠的比率，并且可以基于该比率进行调整。 在一些实施例中，也考虑可接受性参数。 在一些实施例中，调查元件可以被引导以增加附加的唯一折叠，而不会留下违反可接受性标准的覆盖孔。 在一些实施例中，自动执行转向。 在一些实施例中，覆盖参数以图形方式显示给操作者。
