Sounds in the Ocean
An audio collection of sounds made by marine mammals, fish, and technology.
Spectrograms—shown on the right of each image below—are a way to visualize sound, and represent frequency (Y-axis) over time (X-axis). Colleagues and scientists of the Northeast's Passive Acoustic Research Group collected the sounds on this page.
