Abstract: A technique includes distributing particle motion sensors along the length of a seismic streamer. Each particle motion sensor is eccentrically disposed at an associated angle about an axis of the seismic streamer with respect to a reference line that is common to the associated angles. The sensors are mounted to suppress torque noise in measurements that are acquired by the particle motion sensors. This mounting includes substantially varying the associated angles.

Abstract: An apparatus includes particle motion sensors and a streamer that contains the particle motion sensors. The streamer is towed in connection with a seismic survey, and the towing of the streamer produces a turbulent flow. The streamer includes an inner cable and a fluid containing layer. The inner cable includes a material to circumscribe and extend along a longitudinal axis of the streamer and circumscribe at least one of the particle motion sensors. The fluid containing layer surrounds the inner cable to reduce noise that is otherwise sensed by the particle motion sensors due to the turbulent flow.

Abstract: Measurement data acquired by at least one sensor in a cable structure towed through a body of water is received. A torsional vibration noise component in the measurement data is estimated. The torsional vibration noise component is used to estimate a rotation angle of the at least one survey sensor with respect to a reference coordinate system of the cable structure.
