Abstract : The integral solution of the sound field is derived from a laminated interbedded liquid-solid half space. The last layer of infinite thickness is solid. The integral over wave number is conveniently transformed into the complex wave number plane yielding a sum of normal modes of propagation plus the sum of integrals along branch cuts. Waves corresponding to the normal modes predominate at ranges beyond several times the water depth and are considered in detail. Sample numerical computations are presented for propagation of Rayleigh waves in shallow water on the Arctic continental shelf. (Author)
