A method of serological exploration of in-water deposits which consists in the first stage of emission into a body of water, in accordance with a pre-arranged program of emission of elastic waves on the other hand, under the surface of the boundary in the upper part of it, the mass of water and in a second stage in the taking in their water and in a second stage in the taking in the water due to reflected waves and the transformation of the corresponding electrons signals according to a predetermined reception program, in which at least one of these programs is implemented by performing at least one of the transmission and reception stages at multiple points on levels at different depths, and at intervals between two successive levels between these two to the velocity of propagation of the elastic waves emitted into the water, in such a way as to make possible the said electric waves generated by the waves reflected by the subsoil layers, accompanied by a phase difference of the electrical signals generated by the waves of the excited under said surface.
