An otherworldly noise that was recorded near the Mariana Trench could be a never-before-heard whale call.
Dubbed the "Western Pacific Biotwang," this newly discovered call might be from a minke whale — a type of baleen whale — according to the researchers who documented the vocalization.

Regardless of what species it is, this whale has range: The call includes sounds that span frequencies that reach as low as 38 hertz and as high as 8,000 hertz. Humans can hear sounds between 20 and 20,000 Hz.
"It's very distinct, with all these crazy parts," Sharon Nieukirk, senior faculty research assistant in marine bioacoustics at Oregon State University, said in a statement. "The low-frequency moaning part is typical of baleen whales, and it's that kind of twangy sound that makes it really unique. We don't find many new baleen whale calls."
The call was recorded with autonomous seafaring robots, known as "passive acoustic ocean gliders," which can dive up to 3,280 feet (1,000 meters) below the surface. Scientists can send these devices out on solo missions to eavesdrop on whale conversations. Nieukirk and her colleagues collected their acoustic data in the fall of 2014 and the spring of 2015, in an area in the Pacific Ocean east of Guam around the Mariana Trench, the deepest part of the ocean.
Please ignore the alien :-)
The next two videos are short and have different and more bizarre audioThe audio from the last video is freaky. I would be terrified if I ever heard it in person. I am still in shock after hearing it.

Now we just need to know if "The Bloop" was Cthulu or not...
The Bloop mystery has been solved
Wired.co.uk spoke to NOAA and Oregon State University seismologist Robert Dziak by email to check it out. He confirmed that the Bloop really was just an icequake

Mysterious Metallic Sound From The Deepest Known Part Of The World's Oceans Finally Identified.
Funny that, Mysterious Metallic Sound From the Deepest Oceans might be a whale.
How long have researchers been recording whale sounds and calls?
How long have they been researching the sounds and calls of the minky whale in paricular. ........................ and It MIGHT be a whale?????????
come on you people just how gullible are you?? - far out !!!!!!!!!!!!!!!
This particular noise was recorded off the coast of Guam in the 2014, and is thought to be from a species of whale. However, there are still aspects of the whale theory that don’t entirely add up.
The noise has been dubbed the “Western Pacific Biotwang” and has been described in a recent publication in the Journal of the Acoustical Society of America. The authors are confident that “these complex sounds were produced by a biological source” which is speculated to be a type of baleen whale, but that note a definitive source is ultimately still a mystery:
We hope others will be able to identify this call in past and future data, and in time identify the source of this sound. More data are needed, including genetic, acoustic, and visual identification of the source to confirm the species and gain insight into how this sound is being used.
The baleen whale theory is complicated by the fact that the sound has been recorded year-round, while baleen whales have previously been known to make vocalizations only during mating season. Furthermore, acoustic analysis has shown that some of the metallic-sounding higher frequencies in the Western Pacific Biotwang are not typically found in whale calls.
