    Abstract: Various methods and apparatuses for facilitating cleaning of submerged geophysical equipment using sound waves transmitted at ultrasonic frequencies are disclosed. In some embodiments, one or more transducers may be configured to transmit sound at one or more ultrasonic frequencies. The sound at ultrasonic frequencies may be transmitted in the vicinity of submerged geophysical equipment, such as a sensor streamer towed behind a survey vessel. Obstructions (e.g., barnacle larvae) adhering to surfaces of the geophysical equipment may be loosened or removed altogether when ultrasonic transmissions occur within its vicinity. The transducers used to transmit the ultrasonic frequencies may be implemented in various ways, such as being attached to a remote operated vehicle, a cleaning unit, or as being an integral component of the geophysical equipment.

    Abstract: Streamers used in mapping strata beneath a marine body are described, such as in a flexible neutrally buoyant towed array. A connector is used to longitudinally join a first and second streamer section and/or to connect a streamer section to a streamer stabilizer. The connector contains at least one of: (1) means for distributing axial stress over a larger volume or along a longer x-axis length of the streamer relative to the absence of the means for distributing; (2) forming an increasing radius of curvature along the length of the connector as a function of distance from the first leading streamer cable section; and (3) co-moving an inner stress bearing element and an outer wall of the connector preventing intermediate streamer elements, such as a wire bundle from picking up noise related to the movement stress.

    Abstract: A seismic cable including sensors, data transmission lines extending the length of the seismic cable for conveying data signals issued from the sensors. Controllers distributed along the seismic cable operate as an interface between the sensors and the data transmission lines. Power supplying lines supply power to the controllers and the sensors. X power supplying lines are alternately connected to one out of X successive controllers. Each controller is adapted for applying on a power supplying line detected as defective the electrical tension provided by another power supplying line. Y data transmission lines are alternately connected to one out of Y successive controllers. Each controller is adapted to redirect towards at least one adjacent controller the data associated with a data transmission line which is determined to be defective.

    Abstract: Sensors used in mapping strata beneath a marine body are described, such as used in a flexible towed array. A first sensor is a motion sensor including a conductive liquid in a chamber between a rigid tube and a piezoelectric motion film circumferentially wrapped about the tube. A second sensor is a traditional acoustic sensor or a novel acoustic sensor using a piezoelectric sensor mounted with a thin film separation layer of flexible microspheres on a rigid substrate. Additional non-acoustic sensors are optionally mounted on the rigid substrate for generation of output used to reduce noise observed by the acoustic sensors. Combinations of acoustic, non-acoustic, and motion sensors co-located in rigid streamer housing sections are provided.
