ABSTRACT:
An apparatus for measuring the shear modulus profile of the seafloor by measuring the motion of the seafloor in three dimensions and the wave induced pressure at the seafloor and converting these measurements into a shear modulus profile using the Yamamoto equation and the linear inverse theory of wave-seabed interaction.
