An example of a 1-D seafloor compliance calculation for a 400 m thick low-velocity layer (of P-wave speed 3.5 km s⁻¹, S-wave speed 1.2 km s⁻¹ and density 2700 kg m⁻¹) embedded in a uniform background (of P-wave speed 6 km s⁻¹, S-wave speed 3.5 km s⁻¹ and density 2700 kg m⁻¹). The compliance shows a peak caused by the presence of the layer. The water depth is 2.7 km.
