Abstract: A system can include a source and a front float coupled to the source. The front float can include a winch configured to adjust a position of the source. The front float can include a control unit configured to control functions associated with the front float. Lead-ins can be coupled to the front float and the source and configured to accommodate transfer of electrical energy between the front float and the source.

Abstract: This disclosure is related to marine seismic sources, for example marine seismic sources known in the art as benders. Some embodiments of this disclosure use magnetic reluctance forces to produce seismic energy. For example, pole pieces may be attached to one or more plates of a marine seismic source, and a wire coil may induce an attractive force between the pole pieces to cause deformation of the plates to produce seismic energy. Such marine seismic sources may be components of a marine seismic survey system, and may be used in a method of marine seismic surveying. Methods of making marine seismic sources are also disclosed.

Abstract: Deploying and retrieving streamer cleaning devices. At least some of the example embodiments are methods including transferring a streamer cleaning device to a geophysical sensor streamer. The transferring may include towing the geophysical sensor streamer through water while the geophysical sensor streamer submerged, towing a tow fish through water by way of an umbilical (the streamer cleaning device coupled within a payload area of the tow fish during the towing of the tow fish through the water), landing the tow fish on the geophysical sensor streamer and thereby abutting the streamer cleaning device against the geophysical sensor streamer, closing the streamer cleaning device around the geophysical sensor streamer, releasing the streamer cleaning device from the payload area, and separating the tow fish from streamer cleaning device and the geophysical sensor streamer.

Abstract: Techniques are disclosed relating to towing source elements and geophysical sensors through a body of water using one or more unmanned tow vessel. In some embodiments, a plurality of unmanned tow vessels are configured to tow one or more signal sources and/or one or more streamers. The plurality of unmanned tow vessels may, in some embodiments, traverse various sail paths along a surface of a body of water in order to acquire geophysical data relating to formations disposed below the bottom of the body of water.
