Abstract: Signals of pressure sensors and particle motion sensors located in marine seismic streamers are combined to generate pressure sensor data and particle motion data with substantially the same broad bandwidth. The noisy low frequency part of the motion signals are calculated from the recorded pressure signals and merged with the non-noisy motion signals. The two broad bandwidth data sets can then be combined to calculate the full up- and down-going wavefields.

Abstract: A seismic streamer includes a jacket covering an exterior of the streamer. At least one strength member extends along the length of the jacket. The strength member is disposed inside the jacket. At least one seismic sensor is disposed in an interior of the jacket. An acoustically transparent material fills void space in the interior of the jacket. At least one longitudinally compressible element is disposed at a selected position along the streamer. The longitudinally compressible element fills substantially all void space within a cross-section of the interior of the jacket to separate the material into two compartments, thus attenuating transmission of acoustic waves in the material across the element.

Abstract: In one embodiment the invention comprises a particle velocity sensor that includes a housing with a geophone mounted in the housing. A fluid that substantially surrounds the geophone is included within the housing. The particle velocity sensor has an acoustic impedance within the range of about 750,000 Newton seconds per cubic meter (Ns/m3) to about 3,000,000 Newton seconds per cubic meter (Ns/m3). In another embodiment the invention comprises method of geophysical exploration in which a seismic signal is generated in a body of water and detected with a plurality of co-located particle velocity sensors and pressure gradient sensors positioned within a seismic cable. The output signal of either or both of the particle velocity sensors or the pressure gradient sensors is modified to substantially equalize the output signals from the particle velocity sensors and the pressure gradient sensors. The output signals from particle velocity sensors and pressure gradient sensors are then combined.

Abstract: A marine seismic streamer steering device comprises at least two hinged sections pivotally coupled to each other and connected between two adjacent sections of the seismic streamer, and a bend control unit that controls bending of the hinged sections relative to the longitudinal axis of the seismic streamer. The steering device further comprises a roll sensor which determines rotational orientation of the body and transmits the orientation to the bend control unit, a lateral position sensor which determines lateral position of the body and transmits the lateral position to the bend control unit, and a depth sensor which determines depth of the body and transmits the depth to the bend control unit. The bend control unit then controls the bending of the hinged sections based on the transmitted rotational orientation, lateral position, and depth of the body.
