Senior level/graduate level text/reference presenting state-of-the- art numerical techniques to solve the wave equation in heterogeneous fluid-solid media. Numerical models have become standard research tools in acoustic laboratories, and thus computational acoustics is becoming an increasingly important branch of ocean acoustic science. The first edition of this successful book, written by the recognized leaders of the field, was the first to present a comprehensive and modern introduction to computational ocean acoustics accessible to students. This revision, with 100 additional pages, completely updates the material in the first edition and includes new models based on current research. It includes problems and solutions in every chapter, making the book more useful in teaching (the first edition had a separate solutions manual). The book is intended for graduate and advanced undergraduate students of acoustics, geology and geophysics, applied mathematics, ocean engineering or as a reference in computational methods courses, as well as professionals in these fields, particularly those working in government (especially Navy) and industry labs engaged in the development or use of propagating models.read more

Underwater acoustic communication channels: Propagation models and statistical characterization
TL;DR: There are no standardized models for the acoustic channel fading, and experimental measurements are often made to assess the statistical properties of the channel in particular deployment sites, but the channel capacity depends on the distance, and may be extremely limited.
Journal ArticleDOI
The state of the art in underwater acoustic telemetry
TL;DR: A primary thesis of this paper is that increased integration of high-fidelity channel models into ongoing underwater telemetry research is needed if the performance envelope of underwater modems is to expand.

Phase conjugation in the ocean: Experimental demonstration of an acoustic time-reversal mirror

TL;DR: In this paper, a phase conjugate array was implemented to spatially and temporally refocus an incident acoustic field back to its origin in the Mediterranean Sea by transmitting a 50-ms pulse from the SRT to the SRA, digitizing the received signal and retransmitting the time reversed signals from all the sources of the sRA.

Underwater noise of whale‐watching boats and potential effects on killer whales (orcinus orca), based on an acoustic impact model
TL;DR: In this article, a software sound propagation and impact assessment model was applied to estimate zones around whale-watching boats where boat noise was audible to whales, where it interfered with their communication, caused behavioral avoidance, and possibly caused hearing loss.

Extracting coherent wave fronts from acoustic ambient noise in the ocean
TL;DR: In this paper, a method to obtain coherent acoustic wave fronts by measuring the space-time correlation function of ocean noise between two hydrophones is experimentally demonstrated, which exhibits deterministic waveguide arrival structure embedded in the time-domain Green's function.
