Acoustic Effects of Internal Microstructure

Abstract

Since the purpose of this meeting is to promote the interaction of oceanographers and acousticians, I'm not going to talk about some of the very interesting mathematical problems that arise in the theory of the scattering of waves by a randomly-inhomogeneous medium: multiple scattering problems, the details of the controversy surrounding the Born and the Rytov method of approximately solving the wave equation, the question of gross inhomogeneities, etc. These are all quite interesting but, I believe, relatively unimportant in the context of oceanographic measurements and modelling. I will concentrate instead on the two sides of the single question of interest here: what does the microstructure of the ocean do to an acoustic wave traversing it, and what can measurements of acoustic waves tell us about the ocean microstructure. Much of our small successes in this field, as in other fields of physics, have come about because of a suitably narrowly-defined area of interest.
