Physics of Seismic Interface Waves in the Surf Zone

Abstract

Our long term goal is to develop the basic physics of micro seismo-acoustics so as to enable the development of seismic sonar for the detection of ordnance buried in sea floor sediments. We seek to determine the potential of the seismo-acoustic interface waves for the detection of objects buried just beneath the water-sediment or air-sediment interface. We need to determine the unique potential of the various types of seismo-acoustic interface waves (ie Rayleigh, Scholte, Love, Lamb, etc.) for this purpose. We want to determine how these different wave types propagate in the surf zone sediments, and which may be best suited for the purpose at hand. Finally, we seek to determine the potential for discrete excitation of individual seismo-acoustic wave types.
