Listen to livestream sound from the sea floor, will you be lucky to hear the dolphin?

Researchers at MBARI put the microphone down to a depth of 914 meters, recording the soft sounds of life in the deep sea.

It can be confidently affirmed that you never know what sound the sea floor has. But things will change with this livestream: researchers are putting the recording microphone under Monterey Bay, at a depth of 914 meters below the surface of the water.

This is a project of the Monterey Bay Aquarium Research Institute (MBARI) in 2015, about 29 km off the coast of California. Livestream still runs until now, letting you hear the soft sounds of the sea floor, here and there the sounds of dolphins, sea lions and animals that live here.

Super sensitive microphone.

This ultra-sensitive microphone is also called a hydrophone , which is attached to MBARI's ocean view station, connected to the mainland by a sea cable. The Monterey Research Acceleration System (MARS) provides power for the observation station, providing a signal transmission path that operates continuously 24 hours a day. Thanks to that, we have the above livestream.

MBARI said about this project:

"The hydrophone is not very impressive. It is just a metal tube 5cm in diameter, placed on a three gauze under the seabed filled with mud. But it is extremely sensitive, can receive many different sounds, including sounds that are too low or too high for people to hear. "

MBARI also added that occasionally, the hydrophone catches the sound of species on the surface of the water:

"The dolphin's voice does not go too far in the water, but if the sound appears, then the dolphins are within a few kilometers of this hydrophone. However, the sound of the boat engine can be It took tens of kilometers, some whale sounds could come here from a few hundred kilometers off Monterey Bay ".

This Livestream also gives us a closer look at Monterey Bay.

In addition to being very interesting, this livestream gives us a closer look at Monterey Bay, a place listed by scientists at MBARI as "very tight-lipped". These data play an important role in the research project of Monterey Bay, the federal government listed more than 15,000 square kilometers of the area under protection. Also from this study, scientists know that blue whales have lowered the frequency of their songs, because boats make so much noise.

"For the first time we heard these sounds, we thought it was great and wanted to share with the community," said John Ryan, the research leader at MBARI. "There may be times when the ocean will be very quiet, but then it can become lively in just a few minutes. If you turn on and don't see anything calm, it will definitely be different."
