Various technologies for a method for processing seismic data. In one implementation, the method includes cross-correlating seismic traces having midpoint locations, offsets and azimuths within a predetermined range but from different sequences; and selecting a peak on each cross-correlation. Each peak corresponds to a difference in travel times between two seismic traces that were cross-correlated. The method further includes converting the difference in travel times between the two seismic traces to a difference in water velocities between a pair of sequences associated with the two seismic traces at a spatial location.
