Let us now give another example of gap deconvolution. We shall illustrate the method of predictive deconvolution for the case of a water layer, which produces a reverberation train. Suppose the water depth is 100 ft (30 m). Let the water-surface reflection coefficient be unity, and let the water-bottom reflection coefficient be 0.5. Let the velocity of the water be 5000 ft (830 m)/s. Then the two-way normal-incidence traveltime in the water layer is 2(100)/5000 = 0.040 s, which is 40 ms. Assume that the sampling increment is 4 ms, so that the reverberation cycle time in discrete units is 40/4 or 10.
