Abstract
C-33 VECTOR-FIDELITY DIFFERENCES BETWEEN P-WAVE FIRST BREAKS AND PS-WAVE REFLECTIONS – IMPLICATIONS FOR COMPENSATION OF FULL-AZIMUTH DATA Abstract 1 Coupling in seabed data is well understood and has been characterized by damped oscillatory systems that vary in amplitude and phase as a function of frequency. Furthermore compensating for these effects has in general met with positive results. Recent studies in vector infidelity have focused primarily on the direct arrival of seabed data and suggested that cable-sensor data are not qualified to acquire full-azimuth data. However the direct arrival response is related to a different part of the overall coupling resonant
