Webdisplacement of the wavefield is the difference between the up-going and down-going wavefields. Since the hydrophone records the pressure wavefield and vertical geophone records the velocity of displacement of the wavefield, we can write the Loewenthal et al. (1985) equations in terms of the hydrophone and vertical geophone data as follows: WebMar 10, 1992 · In dual-sensor, bottom-cable marine seismic exploration where hydrophone/geophone pairs are deployed on the marine bottom, coupling imperfections between the geophones and the marine bottom contribute to differences between the impulse response of the geophones and the impulse response of the hydrophones.
