Fundamentals of Computational Ocean Acoustics

Sound is the primary tool for exploring, navigating, and communicating in the vastness of the world's oceans. Understanding how acoustic waves travel through complex, stratified marine environments is essential for modern marine research, engineering, and environmental monitoring. This course guides you from the fundamental physics of sound waves to the practical application of computational models. You will learn to analyze and simulate how sound behaves in diverse underwater settings, from shallow coastal waters to deep ocean trenches, using structured mathematical formulations and modern numerical approaches. What you'll learn: - Understand the fundamental wave equations governing sound propagation in fluid and visco-elastic marine media. - Explore wave-theory formulations for acoustic source radiation and seismo-acoustic propagation in stratified ocean waveguides. - Apply Wavenumber Integration and Normal Mode methods to model sound propagation in plane-stratified oceans. - Analyze Parabolic Equation and Coupled Mode approaches for simulating range-dependent ocean environments. - Model seabed interactions, ice covers, target scattering, and ocean ambient noise. - Implement basic numerical simulations using modern computational scripting to solve acoustic wave equations. This course begins with key terminology, basic physical concepts, and foundational definitions of underwater acoustics. You will then progress through increasingly complex propagation models, exploring both range-independent and range-dependent environments through clear, step-by-step written explanations and theoretical code snippets. This course is designed for beginners to ocean engineering, marine science, or applied physics who want a solid computational foundation. No prior experience in ocean acoustics is required, though a basic familiarity with calculus and introductory programming concepts will help you get the most out of the material.
