Bjurälven 2015 - "The Secret" - Air filled cave tunnel 

lol

Lol

:)))

😂😂😂😂😂😂😂

😀😀

I am not a cave diver yet, but I know that feeling from when I stay with days underground. One of the most peaceful experiences ever!

alek why do you stay underground and where ?

@@faheema6736 Well, I am exploring a big cave and I have to stay there because only the way to the new passage takes us one or more days. Of course there are some sumps, but we can't explore them because it's almost impossible to haul all the diving gear there.

Is this fully underwater

@@akashkvkkrishnan7374the 500 meters to reach the air chamber is fully underwater, yes

Exactly what you said

they should name claustrophilia the opposite of claustrophobia.

Nikke DosE the map is for you that wants to stay safe, we push outside the map and draw the map for you.

Callum W relatable

I want to make an indoor pool with rock floor walls and ceiling from the rocks at 4:58 or at least a bathroom

Callum W m

Callum W so many geeks comparing real life to a goddamn game.. like go outside already!

BRICKCITY9MM Someone's kids could see thus

prob alot fo corpses along the way

@gareth5000 I have the same thoughts almost everytime I watch cave diving, or regular caving ((I don't know the right term)). I always hope they'll do like a part 2 that shows them going further past where they had to stop before. I KNOW that realistically it's not always positive.

Spelunking or speleologyI believe. Google Édouard-Alfred Martel. I read a fascinating book about him when I was a kid.

THEY ALL FLOAT DOWN HERE.

Gosta look tween'em crannies bruv

barbaric

Inconceivable!

2394098234509 Yet soothing and peaceful.

like inside animal's stomach esp whale XD

2394098234509 - was thinking same. I assume those droplets are from the body of water above, ice, snow, or whatever?

Erick McGee I'd kill myself

A well trained cave diver will never dive without a buddy, and each person will have at least 3 lights, so there's a lot of redundancy for things like that.

Actually in Britain it's standard to dive solo because the passages tend to be tight and full of sediment so after one diver has been through visibility is often zero. They may dive with one or two other cave divers but they leave large gaps e.g. 10-30 mins between divers to allow the sediment to settle, so basically you're on your own. US cave divers are normally trained to dive in threes if they're in large passages with fantastic visibility like the blue holes in Florida or the Bahamas. The idea is that you can buddy breathe if someones equipment fails. As you say it's standard for cave divers to have at least two of every system (except their dry suit) in case of any problems. And similarly to dive on the "thirds rule". i.e. a 1/3 of your air on the way in, a 1/3 on the way out and a 1/3 for emergencies. If using scooters you need to increase that margin in case the scooter fails.

Or worse imagine something happen with tube and can’t breath through it

Imagine you flashlight goes out, and then you hear someone else in the cave。

+Anthony Masters Yes, sure will and thanks for watching

*through

That's Right after the spring flood that will flood the whole tunnel, new air from the outside will penetrate cracks in the ceiling. If the ceiling would be air tight, the water would stay in the tunnel because of the pressure. The water level is the same as at the entrance.

not to mention after a while the oxygen would be used up so to speak

A human at rest consumes roughly 240 Liters of air per hour and not all the oxygen is removed by our lungs from a breath. Depending how much space 240 liters of air takes up and I'm sure depending on the air pressure down there as well, those caves I'd guess several hours based on how big they looked? Again I haven't done even rough math for the cave size and original oxygen content.

QhahahHajahahah that was a good one. Classic

TricoCosmic It will "take" away from the next group of divers.

TricoCosmic it be like a bong and go through the water

Yes it is a beautiful cave. More videos on my channel.

Id love to see your faces when you got back and your tanks had disappeared..good job

@@dyktilja just seen you're secret air filled cave czn you provide me with some more information?

+Sourav Sinha I think they have some ponybottles with them

Sourav Sinha no its winter when the snow melts the cave will fill. it flows out of the gravel (conglomerate) they keep an eye on the weather so they don't get caught out

Sourav Sinha I feel like a lack of oxygen would be more dangerous

40E Well the problem isn't lack of oxygne, it could also be if it is pure oxygen, which can be deadly

Flamefart8 there is no way that air is pure oxygen. Also, pure oxygen is not deadly, you are breathing something like 99% oxygen in scuba tanks

Simon Dent poor song choice definitely

Why was this funny

I think the only way the water could have flooded in that pocket is if there was a crack formed reaching either another water source or opened up to the ground level. The pressure was preventing the cave to flood. Take a cup and turn it upside down and force it into the water, the only way water can fill up is by drilling a hole into the cup or turning the cup upside down. But yeah you're right, if an earthquake were to happen and caused a crack leading to the topside...they would have been in trouble.

@@templarzrise5086 you can tell water flows through the entire cave, look at the walls. This cave fills with water when the snow melts, that's why they were able to take their gear off without worrying.

@@templarzrise5086 If a crack did form very suddenly, the cave would also very violently and suddenly fill with water.

BeebleBoxn Yes its called the volume button on your device and your welcome.

Wasn't complaining about the music I just wanted to hear the sounds of the cave. I was asking the uploader not you. K:) Thx

BeebleBoxn ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JVhZMcBOPWE.html

Hey thanks those are always relaxing.

BeebleBoxn 🍻

People are exploring unknown amazing discoveries and your dumbass is thinking about gold?

and then causing a tunnel collapse

@@OCDlosp it means no one is going to touch him anymore 😂

Pretty sure they are not the first ones going there. You can see the lines being already attached from previous explorers

I’m the same way and yet I go caving. 😂

only if you smoke a joint there

This is something I would like to know as well.

Very well then

I would think the limestone would actually take away the Co2 over time like a sponge.

Angelo Santelli not sure if what these guys are saying rings true, but common training is to not breathe air in air pockets in overhead environments. Because you can't be sure of the content of the gas unless you have a analyzer, its best to stay breathing your tank air, however it's perfectly fine to take your reg out of your mouth and you can talk back and forth. Just don't breathe the trapped air, it could knock you out, and is a easy and stupid way to die.

humanimal Its erosion due to flowing water during the summer months, the cave is only full of air during the winter when the ground water us frozen. When all of the snow melts its flows through the cave slowly carving away creating the odd texture.

To life with so huge balls is uncomfortable.

Bloo57999 we took the stairs maaaan

Yeah good luck getting that shit under water, maybe YOU should stop smoking doinks kid

Its a joke you spastic fuck

金3 A.M. you put it in a waterproof container these guys said they had hot chocolate

Pehz who's spastic now? Did I beat your kids too hard? 😂😂😂

Broke plebs can still explore terrestrial caves

You missed the point - it's not a video game, this is a real place, it's not about the music its content, a place that is incredible beyond imagining, an exploration that is about as extreme as it can ever get. Understandably your life experience limits you, but when commenting on something like this try and understand the bigger picture.

LOL

I too am a veteran ,it does not qualify me to say stupid things.

I was addressing GazetteFan4life, not you, but the point remains, the bigger picture is the content of the video, an incredible place beyond all imagining and most people watching this will be seeing that and be astounded by the exploration and pristine environment. As for hearing nature, you wont hear crickets chirping and frogs croaking under there- without water noises it is as silent as death.

GazetteFan4life I

ESPSJ I actually enjoyed the video . It doesn't the act is amazing , these are brave men

Lol same

ESPSJ haha! I didn't think it was that bad but my cat reminded of how unbearable it actually was when he left my side to go under the couch about 30 seconds into the music.

wow I was about to comment how I liked the music :)

Well i hated the music

There is a coffee vending machine down there. Java, Espresso, Cappuccino, it has it all.

ahhhh thanks lol

"For when you want to enjoy your coffee in peace" xD

Mohite Navinchandra obviously a natural coffee spring in the cave

Air tight thermos

Hahah

That was one brave little trout. He didn't even care.

looks Finnish

Did you know there's this fancy thing called a mute button? It's pretty advanced stuff, don't be discouraged if you don't figure out how to use it the first time.

@Meikkhaell Did you know there are awesome diving videos that don't have annoying music over the raw footage? As far as your sarcastic insult, have a great day /s

andy mate you clearly English it's good to see some one from the uk in the comments

+Jay Cartwright pommy poofters ya tossers

:)

Michael Abelson Lol, yeah. Here where I live criminals have buried drugs underground on farms to hide them. Police still find them though, amazingly.

Kirsty Martin I try and hid from my wife but she still finds me

Fire Blade890 Haha, we women are great husband hunters 😂

Yeah and they would be dead in days.

Mike Abelson you dumb as hell, you would be tracked by police dogs and you wouldn't know about how to navigate it unless you were a seasoned professional in cave diving

respect the nature

Haha
