Abstract
A method of seismic prospecting offshore by means of at least one pair of hydrophone-geophone sensors disposed at the water bottom, in which a sound source at the surface of the water emits a sound signal and the sensors at the water bottom take hydrophone and geophone recordings H and G, the method comprising the following various steps: a filtered signal is determined such that: M=H.sub..DELTA. -G.sub..SIGMA. with H.sub..DELTA. =1/2(H-H.sub.R) and G.sub..SIGMA. =1/2(G+G.sub.R) where H.sub.R and G.sub.R correspond respectively to the recordings H and G propagated over a go-and-return path through the layer of water; and the data obtained in this way is processed to deduce therefrom information about the geology of the subsoil.
