Fin whale call sequence analysis from tracked fin whales on the Southern California Offshore Range

Time difference of arrival (TDOA) methods were utilized to localize and track fin whales on the Southern California Offshore Range (SCORE). In several instances two whales were shown to converge at the same location on the range. Analysis of 20 Hz call sequences revealed changes in call type and intercall-interval coinciding with changes in swim kinematics of the nearby transiting whales. Call sequence analysis may provide some insight on the ability of fin whales to convey information to conspecifics on location and bearing of travel.
