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: A computer-implemented method includes accessing a set of multicomponent marine noise data exhibiting a plurality of polarization vectors at each of a plurality of co-located pressure and particle motion data points on a marine seismic survey apparatus; and determining a set of perturbation noise data for the marine seismic survey apparatus from the polarization vectors. Computer readable program storage media are encoded with instructions that, when executed by a processor, perfume the computer-implemented method. One computing apparatus is programmed to perform the computer-implemented method.

Abstract: An apparatus includes particle motion sensors and a streamer that contains the particle motion sensors. The streamer is to be towed in connection with a seismic survey, and the towing of the streamer produces a turbulent flow. The streamer includes an inner cable that contains the particle motion sensors and a fluid containing layer to surround the inner cable to reduce noise otherwise sensed by the particle motion sensors due to the turbulent flow.

Abstract: The present invention provides a method and apparatus for seismic data acquisition. One embodiment of the method includes accessing data acquired by at least two particle motion sensors. The data includes a seismic signal and a noise signal and the at least two particle motion sensors being separated by a length determined based on a noise coherence length. The method may also include processing the accessed data to remove a portion of the noise signal.
