World Oceans Passive Acoustic Monitoring Day

Scientists all around the world participated in a global study of aquatic sound on June 8th, 2023. Underwater sound recordings from over 250 sites all over the world will be shared to create a snapshot of the cacophony of noises generated by wildlife and humans.

Scroll over the sites marked with stars to hear some of the interesting sounds that have already been submitted from the study!
