Odontocete Sonar Systems Research — Future Directions from a Ethologist’s Personal Point of View

  • R. P. Terry
Part of the NATO ASI Science book series (NSSA, volume 156)


The last decade of research on dolphin sonar capabilities expanded and clarified basic information previously in existence. Significant progress was achieved in understanding aspects of biosonar such as radiation patterns of sonar emission, physical components of odontocete sonar signals and the limitations of their discriminatory capabilities. Fundamental aspects of cetacean sonar capabilities are, however, still only partially understood. Elusive topics yet to be adequately addressed include the role of sonar in communicative behavior, the morphological basis for sound production and the information value of cetacean vocalizations.
