The large velocity dispersion recently reported could be explained by a gap stiffness model
incorporated into the Biot model (the BIMGS model) proposed by the author. However, at …

Background The seafloor is an essential ocean boundary, and the detection of seafloor
information is necessary basis for seafloor scientific research. The classification and …

In our previous work, the strain gradient nonlocal Biot poromechanics model was proposed,
in which two key size parameters, ie, the nonlocal parameter and scale factor, were …

Seafloor reflection loss and roughness measurements were taken at the Experimental
Validation of Acoustic Modeling Techniques experiment in 2006. The magnitude and phase …

Sound propagation in water-saturated granular sediments is known to depend on the
sediment porosity, but few data in the literature address both the frequency and porosity …

Compressional wave speed and attenuation were measured for water-saturated granular
media employing five kinds of glass beads having unimodal and bimodal grain size …

Sediment acoustic models contain two connected components, the geo-physical description
of the sediment and the model of acoustic processes. Geo-physical descriptors are used in …

Estimates of in situ porosity and permeability in saturated soils are important in various
disciplines. In this research, a recently proposed concept for quantitative integration of …

The acoustic properties of piston core sediments are generally measured through a pulse
transmission technique from multiple sediment samples taken from vertically incised core …

Sound speed dispersion and frequency dependence of attenuation in marine sediments are
important for any undersea activities using acoustics, such as remote sensing and target …
