Summary:
B017 Polarisation Analysis of Ocean Bottom 3C Sensor Data B. Olofsson* (Multiwave Geophysical Company member of CGG group) & C. Massacand (Multiwave Geophysical Company member of CGG group) SUMMARY We analyse seismic polarisation of direct and reflected PS arrivals on multi-component ocean bottom (OB) data by mapping vector fidelity as a function of azimuth and angle of incidence at the seabed. We compare data from a cable system with data from nodes as well as buried and unburied cable sensors. As expected nodes show overall best vector fidelity. For OB cable data on the other hand buried sensors show significantly
