Low-frequency
sound in the ocean can be "viewed" in the form of time versus frequency
"spectrograms" (warm colors represent
strong energy) or "listened to" if the natural sound is raised to human
hearing by "speeding up" the original signals. These sample sounds represent
seismic and biological sources, as well as sounds of unknown origin.
