P178 EFFECT OF VELOCITY TRANSITION ZONES ON THE APPARENT POLARIZATION OF OCEAN- BOTTOM CABLE DATA Summary Velocity transitional zones in shallow marine sediments impact the processing and interpretation of ocean-bottom cable multicomponent data (OBC). These sediments act as a polarization filter that reduces the amplitude of converted waves on the vertical component of OBC data. Based on the models considered in this work such influence is essentially independent of frequency in the seismic band. These observations are reached by modeling realistic earth parameters and applying a total elastic algorithm that includes all wave modes. Introduction Over the last decade ocean-bottom
