Upsweep sound

[HeavenWolf108]

It's Slow Down's children.

[Tycholarfero]

@FreddyMercurysAIDS 54° S 140° W, That's pretty far off from Mainland. Unless you count Antarctica, of course.

[DeadIslandFreak]

Makes me think of Silent Hill..

[angeluscaligo]

Well, if this was recording above water, I'd say it's the sound of a certain kind of monkey that has a yell that can be heared up to 5 km away. Don't really remember their name though... But it can imply that it indeed is animalistic in nature.

[zylaurz]

It sounds like a whole bunch fo whales....or maybe something related to dolphins or sharks or whales :s

[gyro231995]

I disliked this to be a douche. It is a good video, but seeing that it has 50 likes and not a single dislike, I couldn't help myself.

[Farvai0]

They say this sound is posseble to hear throughout all of the Pacific, then why come they can track it down and find out what it is?

[SvenTviking]

Its a car alarm. Some scouser has just "Twoced" a car and dumped it in the mersea minus its wheels.

[ocirnus]

Será la voz de las sirenas?

[sh0g0kawada]

bloop and julia are fucking

[iStoleUrToaster]

No joke.. My dog doesnt respond to anything i usually have on my comp or TV.. just played this and he freaked out like no other. strange, huh?

[paddymoep]

@iStoleUrToaster That's because of the frequency.

[Nagisa1984]

UNA SIRENA ESTA DANDO A LUZ ...

[InfernoPervers]

So THAT'S where I left my cellphone

[ror3dracer01]

OHHHH thats where the theif dumped my car off

better turn the alarm off

[MrGunguy2]

id say blue whale but far to loud

[ALTJ1986]

sounds like whales mating

[pwninator345]

I would say Cthulhu, but I'm going to be different and say it's Dagon.

[poposhka123]

so this is where all the confrontational loonies of the internet hang out.

[zylaurz]

actually really sick of this 'Ctthulhus' thing. ITS A FICTIONAL MONSTER. GROW UP.

[celophysis5454545]

@zylaurz You missed the point of Lovecraft then.

[whitewolfwithblackSP]

I almost want to say that they are talking in groups....

[lordxeras]

IA! IA! CTHULHU FHTAGN!

[WingsONE]

secret base where rappers develop new, more annoying sounds to put in their songs

[Djabcd123dB]

It's stuff like this that makes me fear the ocean like crazy. 

[RRyyas]

Alright... Who called the waterproof cellphone in the pacific ocean's deep?

[MushroomPictures]

most interesting underwater sound i have heard

[Angelsilhouette]

Yearly evacuation drill from the underwater mer-cities? :p

[welcomehome901]

Sounds like the evil alien dungeons from Earthbound.

[N412MC]

You are all a little late. ( about 7 years too late) It has been determined that these sounds come from the ocean floor due to seismic activity.

[zelikki]

@N412MC What is your source for this information?

[electronicoffee]

@N412MC WRONG DUMBFUCK. 1 sound was LIKELY THEORIZED to come from the seismic grind of ice upon the crust of the earth (the clip known as 'slowdown') because of it's SPECIFIC WAVE PATTERN. The rest of these sounds are treated as 'organic' and coming from a 'living source' according to most current scientists.

[mazman3434]

Posieden had a car alarm installed?

[Horrorlord1]

@mazman3434 It's Poseidon you ignorant fuck. Learn to spell something else than english!

[MonSwon]

@Horrorlord1 criticising spelling is the lowest form of argument on youtube.

[missingno4894]

USSR sub pen

[TheShadowman60]

To Quote Rage Quit:

"And That Beeping Is So Fucking Annoying BEEP, BEEP-BEEP, BEEP

HOLY SHIT YOUR FOOD'S FUCKING DONE TAKE IT OUT OF THE MICROWAVE"

[SiNSoundtrack]

omg maybe its an alarm from an underground secret biological mutation lab n de mutants r escapin!!

[RenegadeSquirrels]

Sounds like the scream of some random black metal band.

[SilverBlade784]

Lol, I love how these videos are filled with Cthulhu comments.

[DV8R001]

@SilverBlade784 Cthulhu eats like a pig.

[heartsforcats]

I would say its an alarm or siren, but its in the ocean...

[roswellatup]

why are all these strange sounds heard in the southern hemisphere?

[renatonovis]

@roswellatup I don't know...but I live in the southern hemisphere and I'm scary O___O

[LeonClard]

Frogs?!

[nitojo7]

it sounds like Howling monkeys or a ships fire alarm sirens. But the sea is a mysterious world.

[MusicOfAdam]

Perhaps it's a submarine? Idk...

[Noble695]

Is this underwater? It sounds like Starcraft.

[Valti3les]

Its sealab!

[WaldronicTomotron]

I am fascinated by 'Julia' in love with the 'Bloop', but this one is the truly the most interesting.

I can't help but think... Bioshock.

[111E982a]

It sounds like a few animal calling, you know like penguins do when their mum comes back from hunting.

[sprocket2cog]

@111E982a except it was heard across multiple sensors across an entire ocean, shit they must be loud penguins :)

[andyfitz1212]

The curiosity is driving me mad!

[BCRichShredder]

I really hope Cthulhu hit the snooze button. :<

[uranusskies]

MAGLEV REVERSING

[yourleaderDrChaos]

Ok, so they have trains and some kind of alarm on the bottom of the sea? Is this the lair of a James Bond villain or what?

[ZomgGDM]

It's a secret underwater volcano lair klaxon going off.

[damic]

Its Cthulhus alarm clock going off...

[maybeIfailed]

@damic five more minutes...

[kirst0ne]

"He told New Scientist that most can be explained by ocean currents, volcanic activity -- Upsweep was tracked to an undersea South Pacific mountain that had not been identified as "live." "

From an article on the CNN website.

[Brononymousdesu]

CTHULHU!

[RunFast5000]

You say it's seasonal, does it say when? Is it around the equinox of both seasons?

[Yuhi33]

@RunFast5000 I believe so.

[RunFast5000]

@Yuhi33 Thank you.

[Yuhi33]

@RunFast5000 np man, I might upload natural sounds in the future to give people more insight on these unknown sounds.

[RetroGamerSoul]

@Yuhi33 Call me crazy, but it sounds like machinery, but at the same time, strange and bizarre.

If it indeed is organic, is there reason to believe that the sound is emitted from one source and not multiple sources?

[Yuhi33]

@RetroGamerSoul hard to say, like i said, it seems to be seasonal so it may be biologically relative, or something more...

[shotgunner211]

@Yuhi33 

[jiggly229]
