Note that the acoustic wave (visible as an arrival near 40 ms) is attenuated (the shot was buried for this record). Note the prominent reflection near 225 ms that splits into two arrivals near line distance 610 m. Such qualitative changes are the usual interpretative result of a common offset survey.
