Noise Types And Their Attenuation In Towed Marine Seismic: A Tutorial

The presence of noise in towed marine seismic data is a longstanding problem. The various types of noise present in marine seismic records are never truly random. Instead, seismic noise is more complex and often challenging to attenuate in seismic data processing. Therefore, we have examined a wide range of real data examples contaminated by different types of noise including swell noise, seismic interference noise, strumming noise, passing vessel noise, vertical particle velocity noise, streamer hit and fishing gear noise, snapping shrimp noise, spike-like noise, cross-feed noise, and streamer-mounted device noise. The noise examples investigated focus only on data acquired with analog group
