Abstract
In this chapter we mathematically describe how sound propagates through the ocean. This is the study of sound in a fluid waveguide, i.e., a fluid with bounding walls, the surface and bottom of the ocean. Sound is a small amplitude wavelike disturbance on the hydrodynamic background and thus we must first describe the properties of the fluid equations. We derive equations for these properties in Sect.2.1 from first principles, but briefly, and then obtain the equations governing the sound field which we discuss in more detail in the remaining parts of this chapter.
