Abstract
    This paper presents an analysis of sonar pulses from a wild dolphin, recorded at sea in conditions of low underwater visibility. The use of a recently developed, very high resolution, speech spectrograph to examine the recorded data has enabled the structure of the dolphin echolocating pulses to be analysed in some detail. The authors identify several modes of dolphin pulse emission and have endeavoured to relate these to observed behaviour. The conclusions support the hypothesis of very sophisticated signal processing in the dolphin's acoustic sensory mechanism.
