Light Bulbs Used for Seismic Illumination

P053 Light bulbs used for seismic illumination Abstract 1 The roughness of the sea surface affects the quality of towed marine seismic data. This has been shown (Laws and Kragh 2002) to be a potentially significant source of error in time lapse seismic. Methods for correcting this error have been described (Kragh and Laws 2001; Rosten et al. 2002; Robertsson and Kragh 2002; Kragh et al. 2004) and some of these methods require knowledge of the shape of the sea surface above the streamer at all times during the seismic record. Methods have been developed (Kragh et al. 2002) for
