This paper reviews the progress in geoacoustic inversion over the past several decades.
The review is separated into two parts. The first part reviews developments in model-based …

The debate on the sound speed dispersion and the frequency dependence of sound
attenuation in seabottoms has persisted for decades, mainly due to the lack of sufficient …

A multi-range vertical array data processing (MRP) method based on a convolutional neural
network (CNN) is proposed to estimate geoacoustic parameters in shallow water. The …

The double-porosity theory of wave propagation in rocks considers a single scale based on
soft and stiff pores, and wave attenuation occurs by local fluid flow between these pores …

An inversion scheme based on time-warping is presented for estimating seabed sound
attenuation from modal dispersion of close-range single-hydrophone data. The dispersion …

We propose a geoacoustic inversion scheme employing a vector hydrophone array based
on the fact that vector hydrophone can provide more acoustic field information than …

A geoacoustic inversion method based on dispersion characteristic of normal modes is
presented. An adaptive time-frequency analysis technique with a high resolution in both time …

We performed a long range acoustic propagation experiment in the South China Sea (SCS)
in November 2004. The environment of the experiment was with an isothermal sound speed …

Geoacoustic inversion is a very important issue in underwater acoustics, and the inversion
method based on bottom reflection loss is a valid technique to invert bottom parameters …

A propagation experiment was conducted in the South China Sea in 2014 with a flat bottom
and seamounts respectively by using explosive sources. The effects of seamounts on sound …
