Explosion-Generated Seismic Interface Waves in Shallow Water: Experimental Results

Abstract

Seismic interface waves of the Stoneley/Scholte type propagate along the ocean bottom and enable sound to be transmitted at frequencies below the acoustic cut-off frequency of shallow-water ducts. The results of four major sea-trials close to La Spezia, Italy, in the period 1979-81 are presented. The experiments provided a good understanding of the propagation of infrasound in shallow waters, together with some results of the attenuation and excitation of these waves. An attempt was made to explore the use of interface waves for obtaining the values of some of the physical parameters of sea-floor sediments that affect the transmission of these waves.
