About this listen

In 1997, underwater sensors operated by NOAA detected an extraordinarily powerful sound in the Pacific Ocean. It was picked up thousands of miles away. Its origin was never definitively identified. Some scientists proposed a natural explanation. Others considered possibilities that remained inconclusive. The recording, known as "The Bloop," remains one of the strangest sounds ever captured beneath the ocean's surface.
