摘要: Recently it has become apparent that shear properties of ocean sediments are most easily determined from measured propagation characteristics seismic interface waves. We use a newly developed numerical model wave in horizontally stratified viscoelastic media to reconstruct Scholte-wave records the shear-speed and shear-attenuation profiles upper sediment layers shallow-water test area. For an unconsolidated sand-silt bottom we find speed increase with depth 85 m/s at sea floor 300 60 m depth. On other hand, attenuation 3 Hz decreases 0.45 dB/λ 0.15 depth, approximately quadratic frequency dependence.
