Abstract: Since 1985 a resident community of Atlantic spotted dolphins (Stenella frontalis), and bottlenose dolphins (Tursiops truncatus), have been studied underwater in the Bahamas.   Over 200 individuals of both species have been identified and observed over the years. In addition to life history information, genetics and distribution, underwater dolphin behavior is recorded using underwater video cameras with hydrophone input. Dolphins use three main types of acoustic signals: frequency modulated whistles (narrowband with harmonics), echolocation (broadband clicks) and burst pulsed sounds (packets of closely spaced broadband clicks). We will look at both narrowband and broadband technology that is used to record and categorize dolphins. In addition to recording dolphin vocalizations, we will explore the use of current pattern recognition software to help categorize sounds, and an underwater interface for cognitive work with wild dolphins in the Bahamas.
