Abstract
A seismic sensor cable system is provided. The seismic sensor cable system may include a cable, a first sensor configured to measure motion of the cable, wherein measurement of motion by the first sensor substantially excludes particle motion associated with seismic waves, and a second sensor configured to measure particle motion associated with the seismic waves.
Claims25
A seismic sensor cable system, comprising:
- a cable;
- a first sensor configured to measure motion of the cable, wherein measurement of motion by the first sensor substantially excludes particle motion associated with seismic waves;
- and
- a second sensor configured to measure particle motion associated with the seismic waves.
1 more element
A method for collecting seismic data, comprising:
- determining a first measurement with a first seismic sensor, wherein the first seismic sensor is configured to measure motion of a platform of a seismic sensor system, wherein measurement of motion by the first sensor excludes particle motion associated with seismic waves;
- determining a second measurement from a second seismic sensor, wherein the second seismic sensor is configured to measure particle motion;
- and
- combining the first measurement and second measurement to generate a noise-attenuated seismic data signal.
1 more element
An ocean bottom seismic sensor system, comprising:
- a noise sensor configured to measure motion, wherein measurement of motion by the noise sensor substantially excludes particle motion associated with seismic waves;
- and
- a particle motion sensor configured to measure particle motion associated with the seismic waves, wherein the particle motion sensor is coupled to a suspension system configured to resonate below a predefined frequency of interest.
