Abstract
In marine seismic exploration, seismic energy is transmitted through a water layer into the earth and seismic reflection signals from subsurface interfaces are recorded. Any undulating water bottom distortion in the recorded reflection signals is removed by replacing the seismic energy velocity in the water layer with a velocity matching that of the earth medium below the water bottom.
