Sediment characterization using seabed seismic measurements

Data from Seabed Characterization Experiment (SBCEX-2022) conducted at the New England Mud Patch (NEMP) off the United States East Coast are analyzed in this study. Broadband Signal, Underwater Sound (SUS) sources were deployed as part of this experiment. Acoustic pressure and three components of particle motion from the SUS deployments were measured on seismic sensor packages (OBX). Polarization analysis using Stokes parameter framework is carried out to highlight the transverse components. The sensitivity of one of the Stokes parameters to modal attenuation is also investigated. Preliminary results, which compare well with previous studies, are also presented.
