Acoustical Energy Generated by the Ocean Waves

Abstract

An estimate of the order of magnitude of the acoustical energy generated by ocean waves indicates that this energy, is large enough to cause an appreciable heating effect at ionospheric levels, where most of it is absorbed. Using data obtained from surface measurements of the pressure amplitude, it is found that relative density changes of the order of 1 percent occur at ionospheric levels. and the suggestion is made that the “twinkling” of cosmic sources of radio waves is a result of this phenomenon.
