Boundary Conditions and Sound Scattering Models for Various Zooplankton.

Abstract

Echosounders are widely used in the remote detection and classification of marine organisms such as zooplankton. In order to interpret the data, accurate acoustic scattering models must be used. Zooplankton present a formidable challenge when attempting to describe their scattering properties. These animals come in many sizes, shapes, and material properties. The animals can be divided into several major categories of gross anatomical groupings; fluid like or weak scatterers, bodies with gas inclusions, and fluid filled elastic shelled bodies. Approximate models according to the different shapes and boundary conditions have been developed for these anatomical types.
