Essence of the method is using of thin spatial structure of the acoustical field reflected from the ocean bottom at normal incidence that permits fixation of the signal amplitude in different points of horizontal plane near water surface and its presentations at some coordinate system. The possibility of this mapping is demonstrated in many natural experiments carried out with mulltielement spatially distanced received antenna. Quality of the recieved map material is defined by its immunity to disturb factors. It is estimated influence of hydrological disturb factors and insufficiency of original information.
