With growing exploration and utilization of the ocean by human beings, sound pollution increases accordingly and significantly. Hence, the impact of noise on marine organisms has become one of the most important research topics. In order to assess th

This paper develops a Bayesian approach to the image source method (ISM) for efficient inversion of seabed reflection data to estimate geoacoustic parameters and uncertainties. Based on the representation of layered seafloor-reflected signals by imag

Collision risk and close interactions of cetacean with marine renewable energy (MRE) devices are among the main concerns and the least documented of the list of potential impacts of MRE. In this study, we developed a method to track in three dimensio

The image source method is based on the study of signals reflected by a sedimentary seabed. It produces an estimation of the geoacoustic parameters of the stratified sediments. The key step of this method is the detection and estimation of the time d

A new geoacoustic method was recently proposed : the image source method (S. Pinson & L. Guillon, JASA, 128, pp 1685-1693). Under the Born approximation, a broadband signal reflected by a layered seafloor can be represented as a sum of signals emitte

Image Source Method is a recently developed method for geoacoustic inversion. Under the Born approximation, the reflection of a spherical wave above a stratified seafloor is modeled as the simultaneous emission of image sources, symmetric of the real
