Abstract
Broadband sources such as SUS charges and Rupture Induced, Underwater Sound Sources (RIUSS) were deployed in the New England Mud Patch in support of the 2022 Seabed Characterization Experiment. Data measured on the Ocean Bottom Recorders (OBX) and hydrophones will be discussed. Five OBXs were deployed on the seabed and four hydrophones were configured as a tetrahedral array on the bottom mounted Geosled. The OBXs measured three components of particle velocities and acoustic pressure. The spatial variability in the dispersion of broadband signals observed in the pressure and particle velocity data will be discussed. Presence of Scholte waves on the OBX data will be explored using the random decrement technique. Results will be compared with modeling using the seismo-acoustic propagation code (OASES). Outputs of preliminary inversions will be compared with core data collected as part of the experiment. [Work Supported by Office of Naval Research.]
