Strange Case of the day: 5 Most Strange Underwater Sounds Ever Recorded
5. Bloop
Bloop is the name given to an ultra-low-frequency underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997.
Their hydrophones picked up one of the loudest sounds ever recorded off the southern coast of South America.
The Bloop (which sounds like, a bloop), was recorded by 2 hydrophones nearly 3,000 miles (4,800 kilometers) apart.
The sound kind of mimics some marine animal sounds, but its volume is too loud to be made by any sea creatures known to science.
Many have linked, the Bloop to Cthulhu - a fictional part-octopus monster created by writer H.P. Lovecraft in 1928.
To date, the exact reason or source of the sound remains a mystery.
As per NOAA, the most likely explanation for The Bloop is that it was the sound of a large iceberg fracturing.
4. Upsweep
This sound was first picked up by the Pacific Marine Environmental Laboratory when they began recording its sound surveillance system SOSUS in August 1991.
For human ears, Upsweep sounds like an ambulance or some kind of a siren.
The strange part of this sound is that it is very seasonal.
Since 1991, almost every season this sound has been heard.
But for some mysterious reasons, it gets louder in the spring and fall.
The source of the sound appears to be coming from area of undersea volcanic activity.
But scientists are yet to come up with a strong explanation.
The overall source level has been declining since 1991, but the sounds can still be detected on NOAA's hydrophones.
3. Julia
Since March 1999 an annual underwater sound has been recorded by the NOAA just off the coast of South America.
For human ears, this weird noise sounds almost like someone cooing or whining.
NOAA researchers suspect the hydrophones picked up the sound of a large Antarctic iceberg running into the seafloor.
Many believe Julia is the sound of a huge underwater sea creature mainly due to the fact that it sounds like something howling deep in the ocean.
Till date, there is no strong explanation of the sound or its source.
2. Slow Down
This sound was recorded on May 19, 1997 by NOAA.
It got its name - Slow Down, because it descends in frequency over 7 minutes.
The sound was detected by sensors nearly 3,100 miles (5,000 km) apart.
The sound has been picked up several times each year since 1997.
One theory says that the source of the sound could have been caused by the friction of a large ice sheet moving over land.
The exact reason is still unknown.
1. Train
It was recorded on March 5, 1997.
For human ears, it sounds like the rub of train wheels against tracks.
There is so little information on this mysterious sound, that further research or investigation is quite diffucult by researchers.
According to the NOAA, the origin of the sound is most likely generated by a very large iceberg grounded in the Ross Sea, near Cape Adare.
So will end today’s strangeness here. What you think, are these mysterious sounds coming from icebergs or is there any mythical creature deep down - that we still don't know about. Let me know.
