A-08 PZ CALIBRATION USING CRITICALLY REFRACTED WAVES Abstract In marine multi-component seismic data the vertical geophone recordings must be calibrated against the pressure recordings to account for differences such as coupling and impulse responses of the measuring devices. One known way of doing this is by applying the equation of motion and minimizing the downgoing energy in a window containing only primary reflections (Schalkwijk et al. 1999). Picking such a window may be difficult if we have a long source signature or when operating in shallow water. In this paper we utilize the same calibration approach based on a window
