An S-wave velocity model was obtained from these data, based on events apparently generated by the source. High variations in the velocity model with depth were observed and related to lithological characteristics. These variations can hardly be observed using surface seismic data. This velocity model can be useful in the computation of statics correction in the processing of converted-wave (PS) or S-wave seismic data, as well as in engineering and other near surface applications.
