Abstract

Summary

The quality of high-resolution marine 8-channel air gun seismic data can be enhanced by correcting for the effects of swell using the average of previously detected depth values. To apply this correction, we detected and calculated the average two-way travel times of sea bottom depths in seismic data acquired offshore near Yeosu, Korea, and then corrected for the differences between the detected and averaged values. Automatic sea bottom detection is required to obtain sea bottom locations from numerous seismic traces. However, it is difficult to detect locations when the sea bottom signal is unclear due to noise generated by the motion of the sea. We chose reliable sea bottom locations within a certain range around the averaged sea bottom depth. We achieved reasonable detection results using our method. Correcting for swell significantly improved noisy data and produced relatively high-quality seismic sections.
