A New Seismo-acoustic Probe For Seabed Measurements

Abstract

A new seismo-acoustic probe has been developed to measure the propagation velocity and attenuation of compressional and shear waves in seafloor sediments. These data provide information important to the study and analysis of sound propagation in shallow ocean areas and for inferring the geotechnical parameters of offshore sediments. The probe employs a vibrator-driven compaction penetration technique to overcome the problems of ship-based openhole drilling and wireline probe entry into boreholes in unstable sediments.
