FIGURE 4.9. Spectrogram of the song from a humpback whale, Megaptera novaeangliae,
recorded from waters off the Hawaiian Islands on
24 March 1978. The x axis represents time and the y axis represents frequency in kHz, The spectrogram is organized as in sheet music, where
each row
is like a bar. The row below the first one starts on the left at the same time as the first row ends on the right. Each row represents
120 seconds, and there are eight rows, so the song took about
16 minutes before repeating. (From Figure 3B of Payne et aI.1983.)
