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 …

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 …

An inversion scheme is proposed, relying upon the inversion of the noise of a moving ship
measured on a single distant hydrophone. The spectrogram of the measurements exhibits …

The problem of acoustic source depth discrimination was introduced as a way to get basic
information on source depth in configurations where accurate depth estimation is not …

The uncertainty of estimating relative channel impulse responses (CIRs) obtained using the
radiated signature from a ship of opportunity is investigated. The ship observations were …

This work shows that normal-mode attenuation coefficients can be extracted from ship noise
and used to estimate the sound speed in gas-saturated sediments. In an experiment in the …

A technique is presented for passively localizing multiple noise-producing targets by cross-
correlating the elevation beams of a compact volumetric array on separate bearings. A …

Over the past 25 years, there has been significant research activity in development and
application of methods for inverting acoustical field data to estimate parameters of …

Matched-field processing (MFP) is commonly used in underwater acoustics to estimate
source position and/or oceanic environmental parameters. Performance prediction of the …

The received acoustic field generated by a single passage of a research vessel on the New
Jersey continental shelf is employed to infer probability distributions for the parameter …
