Do dolphins have “language?” What is the meaning of a humpback’s song? What information does a manatee call convey? Marine mammal acoustic communication is extremely diverse, complex, and many species have neural wiring supporting a potentially sophisticated communication system. Yet in the absence of “Rosetta Stone,” our efforts to decode it have been challenging. Our approach to decoding marine mammal communication is to use large datasets, both audio and video, to analyze behaviors and calls produced by marine mammals in search for individual variation, call categories, and sequential information. This data will be eventually used to conduct the playback experiment to establish the potential function or “meaning” of the call. Understanding form and function of marine mammal communication goes well beyond the quest of whether or not dolphins have “language,” as it has practical conservation benefits: tracking individuals via passive acoustics, warning boaters about the presence of manatees or whales, and using acoustics to evaluate a marine mammal’s health, activities and crucial habitats.
