3000 feet beneath the ocean surface and 18 miles off the coast of California, an underwater microphone has been placed at the bottom of the sea by the Monterey Bay Aquarium Research Institute (MBARI).
The hydrophone is linked to the team’s research facility on the shore by a 52 kilometer cable and allows for continues recording. As well, the sounds are recorded at more than 6 times the sample rate of a CD to allow for the microphone to pick up as many sounds as possible.
The stream is delayed approximately 20 minutes from the current time to allow for processing. Sound files are recorded in 10 minute segments, so every 10 minutes you will hear the beginning of a new sound file.
