Abstract:

This is a collaborative study between LSU and BAE Systems, San Diego, which began on January 1, 2001. The goals of this study are to develop species- and life-stage-specific acoustic scattering models based on morphologically-accurate digitizations of preserved or live-imaged zooplankton from coastal waters off New England and the northern Gulf of Mexico. These models will estimate scattering strength as a function of acoustical frequency, animal size, taxon, and orientation relative to the incident angle. These predictions will improve our ability to estimate animal abundances by taxonmorphological class via inversion.
