N2 - Seismic multicomponent seabed acquisition systems enable us to measure Scholte- and Love-waves propagating along the sea bottom. Scholte- and Love-waves phase velocity dispersion curves be inverted for estimating shallow near seabed vertical and horizontal S-wave velocities, respectively. In general, the inversion is carried out assuming a stratified media of homogeneous isotopic layers. This assumption maybe invalid as the shallow subsurface bellow the ocean bottom may be anisotropic. Compaction and particle alignment can produce vertical transverse isotropy in loose sediments. Obtaining anisotropic elastic properties of the near seabed is important for engineering, environmental, and geophysical exploration purposes. Herein we present a multimode anisotropic joint Scholte- and Love-wave inversion and demonstrate it one a synthetic and a field example.
