Figure 6: The coda after the principal P and S waves is caused by scattering from roughness and heterogeneity near the seafloor. Vertical channel data are compared for receivers at 230, 330, and 430m below the seafloor at azimuths parallel (a) and perpendicular (b) to the spreading direction. A summary of the azimuthal dependence of the coda amplitude is given in Figure 7. [Dougherty et al., 1995]
