Streamer noise reduction with manufacturing techniques

Results of marine geophysical tests show that a highamplitude low-frequency noise wave is propagated through the cable from section to section at a relatively high velocity but is propagated within each section at a relatively low veIocity . This noise wave has been generally referred to as the 'bulge wave' or 'cable jerk'. Results of early tests reveal characteristics about the bulge wave that can be utilized in the streamer design to effectively attenuate this noise.
