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 fractal texture (or fabric) of porous media, which supports fluid flow at different scales, is
the main cause of wave anelasticity (dispersion and attenuation) on a wide range of …

Shallow water acoustics (SWA), the study of how low and medium frequency sound
propagates and scatters on the continental shelves of the worlds oceans, has both technical …

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 …

This paper presents geoacoustic inversion of a light bulb implosion recorded during the
Shallow Water 2006 experiment. The source is low frequency and impulsive, the …

In ocean acoustics, many types of optimizations have been employed to locate acoustic
sources and estimate the properties of the seabed. How these tasks can take advantage of …

While source localization and seabed classification are often approached separately, the
convolutional neural networks (CNNs) in this paper simultaneously predict seabed type …

We propose time-frequency methods to filter dispersive guided wave signals. Guided waves
occur in acoustical propagation (oceanic waveguides), geophysics (layered medium), or …

This paper introduces a single-receiver geoacoustic-inversion method based on dispersion
analysis and adapted to low-frequency impulsive sources in shallow-water environments. In …

Broadband spectrograms from surface ships are employed in convolutional neural networks
(CNNs) to predict the seabed type, ship speed, and closest point of approach (CPA) range …
