FIG. T-4. 3-D surveying (a) Use of a cross-current to pull streamer off to the side; streamer positions are shown at 15 minute intervals. (b) Use of paravanes to pull marine source arrays to the side. Paravanes are also used to pull streamers to each side; sometimes as many as 12 streamers are used with two source arrays firing alternately, giving as many as 24 parallel seismic lines on one pass with the seismic ship.[1]

En-echelon arrangement of successive spreads, as produced in marine shooting when a cross-current causes the cable to drift at an angle to the seismic line. See Figures F-6 and T-4.


FIG. F-6. Feathering of a marine streamer. See also Figure T-4
