In this study, we demonstrate the value of conventional PSwave processing techniques applied to common-receiver gathers. These techniques include the utilization of moveout (hyperbolic and ray based) velocities of P- and PS...

... of its acquisition configuration. In addition to using a cabled system connecting geophones, mashphones, and hydrophones, it also uses an autonomous system of ocean bottom nodes (OBNs). Besides those receivers, five types of sources are employed: three-differently-sized airguns, seismic vibrators...
