N2  - Fictitious time shifts with consequent time and velocity errors are introduced when conventional replacement static corrections are used on marine seismic data, recorded over irregular or steeply dipping water-bottom environments. Correct common depth point (CDP) stacking of seismic reflection signals involves the determination of appropriate time-variant static corrections for different receiver geophone positions. Static corrections are shown to depart from surface consistency over irregular water-bottom environments. To study these problems, raypath modelling has been carried out for two irregular water-bottom situations which are typically complex. A technique is illustrated for determining static corrections in such areas.
