Solid Streamers and Single Hydrophones

A31 SOLID STREAMERS AND SINGLE HYDROPHONES Summary 1 Solid streamers are less sensitive to weather-related noise than liquid streamers. Hence with the solid streamers the operational weather window can be extended. In addition solid streamers can be towed shallower without a prohibitive increase in noise. The application of noise filters on single hydrophones in a solid streamer only yields marginal improvements over application of the same filters on hydrophone groups. These improvements do not justify the introduction of single hydrophone recording. For reduction of weather noise a hydrophone spacing of 3 m may be adequate for solid streamers. However the
