ethology, animal cognition, sensory biology, psychophysics and bioacoustics. Current basic research is focused on the
ontogeny of vocal behavior in North Atlantic right whales and the underlying
causes of ship strikes and vessel collisions with marine mammals (whales and
manatees). Interdisciplinary applied research entails anthropogenic noise and
the mitigation of impacts on marine mammal behavior and ecology. Sponsors have included: U.S. Department of

Psychoacoustic investigations of the West Indian manatee defined the manatees’ overall hearing abilities including their behavioral audiogram, critical masking ratios, and directional hearing. The work demonstrates the challenges manatees have in hearing and detecting approaching boats and barges in their shallow water habitat. A parametric acoustic alarm designed to exploit the manatees best hearing abilities and alert them of approaching vessels has been successfully tests.
Passive acoustic monitoring studies are being conducted with North Atlantic right whales in the critical southeast calving habitat off the coast of Florida and Georgia. The call repertoire of surface active groups has been catalogued and analyzed with respect to structure, behavior and call affinity. The ontogeny of vocal communication between mothers and calves has been investigated over seven field seasons, revealing developmental aspects of behavior including the emergence various call types, their spectral characterizations and frequency of use.
