The output of the ocean-bottom computation from the script DOSEA is similar. The only difference is in the header information. The phase velocity is computed as a funciton of the water depth abd frequency. Since the phase velocities are much greater than those use for the solid-atmosphere problem, the kernels are significant to greater depths. In addition, the model applies to the material in the seafloor and does not have an initial fluid layer. The
