Acoustic wave propagates properly in water, whilst most forms of electromagnetic waves, particularly in salty and dense sea water, are attenuated after a few tens or hundreds of meters so that it will be impossible to trace and detect them. This paper presents a special method for recognizing probable underwater currents, and reconstruction of their intensities, widths, and directions by usin...
