Figure 3. (top) Map of acoustic detections attributed to Pacific white-sided dolphins at M2, M5, and CH with dotted lines denoting historical range extents. Number of files with detections each day are in parentheses if>1. (bottom) A spectrogram from 25 October 2009, at M2 of buzzes with peaks and notches as expected for Pacific white-sided dolphins according to Soldevilla et al. (2008). Spectrogram settings are: window = Hanning, Nfft = 1,024, overlap = 99%, min dB = 12 dB, dB spread = 42 dB.
