The ocean soundscape is a continuously changing mosaic of sounds that originate from living organisms, natural processes, and human activities. Listening to sound in the sea is a rich exploration of the marine environment that even reveals some of the ways human activities may influence marine life.

Acoustics—the study of the properties of sound—allows researchers to “see” animal movements and locations, providing another dimension to our observations of life in the ocean. MBARI researchers are using both established and novel technologies to listen to the ocean soundscape and collect a trove of acoustic data. From a deep-sea hydrophone listening continuously to the underwater soundscape to acoustic technologies attached to underwater robots, MBARI researchers are using sound to study marine life in new and exciting ways.

These teams and projects are changing how we observe marine animals and communities by using diverse technologies to listen to the sounds of the ocean.
