摘要： A marine seismic data acquisition system may include first and second containers deployable in a body of water. The first container includes a first seismic data acquisition channel capable of transducing seismic energy in the body of water having a first maximum amplitude, and the second contain includes a second seismic data acquisition channel capable of transducing seismic energy in the body of water having a second maximum amplitude. The first seismic data acquisition channel is associated with at least a first seismic sensor, and the second seismic data acquisition channel is associated with at least a second seismic sensor. The second sensor corresponds to a same sensor type as the first seismic sensor, and the first maximum amplitude is higher than the second maximum amplitude.

摘要： This disclosure is related to hydrophones, for example hydrophones that may be used in marine seismic surveying, permanent reservoir monitoring, downhole acoustic monitoring in a wellbore, and/or various other applications. Some embodiments of a hydrophone according to this disclosure are constructed such that a longitudinal stiffness of the hydrophone is greater than a circumferential stiffness of the hydrophone. In some embodiments, however, the longitudinal stiffness may be somewhat less than the circumferential stiffness. For example, the longitudinal stiffness may be greater than one half the circumferential stiffness in some cases.

摘要： A marine sensor system includes an enclosure that defines an interior volume. The enclosure is configured to be immersed in water. A sensor having a positive output node and a negative output node is disposed within the interior volume of the enclosure. A first parasitic capacitance between the positive output node and the enclosure is substantially equal to a second parasitic capacitance between the negative output node and the enclosure. A cross feed signal that is propagated through a path in water outside the enclosure is coupled to the output nodes in a balanced manner, which enables a differential amplifier to reject the cross feed noise.

摘要： Sensor receiver nulls and null steering. One example embodiment is method in which a direction from a sensor position to a noise source is determined. A coordinate rotation is applied to a first set of signal values, wherein each signal value of the first set of signal values is based on an output of a corresponding component of a three-component particle motion sensor at the sensor position. The applying generates a rotated set of signal values. The coordinate rotation comprises a coordinate rotation transforming a first set of coordinate axes to a second set of coordinate axes, wherein the first set of coordinate axes has each coordinate axis aligned with a corresponding component of the three-component particle motion sensor at the sensor position, and the second set of coordinate axes comprises a first axis pointed in a direction opposite the direction from the sensor position to the noise source.
