Typical marine sediments are rigid enough to sustain the propagation of shear waves. Reviewed in this seminar is the influence of shear wave coupling on the plane wave reflection coefficient of the seafloor. The following mechanisms are discussed:

§ Coupling of energy into shear waves at the surface of the sediment and the substrate beneath the sediment.

§ The effect of sediment shear waves on interface (Stoneley) waves.

§ Gradient driven coupling between shear and compressional waves.
