Geoacoustic scattering from seafloor features in the ROSE area Academic Article uri icon

abstract

  • A strong "refraction branch diffraction," presumably due to scattering from a lateral heterogeneity on or below the seafloor, has been observed on ocean bottom hydrophone data from the Rivera Ocean Seismic Experiment (ROSE). This arrival is unusual because of its coherence and relatively large amplitude. Finite difference modeling of number of possible seafloor diffractors and associated lateral velocity variations is presented, which demonstrates the occurrence and characteristics of "refraction branch diffractions."
