Ocean - Earth Acoustic Coupling.

Abstract

Experimental measurements to investigate the coupling of guided acoustic waves from a liquid layer of tapered depth into a solid substrate were undertaken. Results indicate that efficient coupling from water into a solid material modeling hard rock occurs principally at depths of less than one wavelength. Higher order locally normal modes were found to be converted to lower order modes without significant substrate radiation. The lowest order mode radiated into the solid as a well defined beam.
