P181 CORRELATION ANALYSIS OF DUAL SENSOR DATA ROY E. WHITE and MARK J. HARRISON Summary 1 The scaling factors required prior to summation of seabed hydrophone-geophone traces can be obtained directly from correlation analysis of the data. The analysis can reveal time and phase shifts between the hydrophones and geophones and can be used to estimate the seabed reflection coefficient. Introduction The summation of appropriately scaled normal incidence pressure and velocity fields at the seabed attenuates both water-trapped multiples and receiver-side peg-leg water-layer multiples. Barr and Sanders (1989) demonstrated the practicability of this approach in the field using a seabed
