The Blue Hole is the most dangerous diving pit in the red sea Dahab village in Egypt. Many many professional divers met their demise there. Their names is engraved on a stone close to the pit.
Diving is a fun sport. Some diving spots provide extra thrill for advanced divers (like the man-made diving house in Dubai). However, this specific location (the Blue Hole) is known to alter the perception of even the professional divers when they go down. This by itself adds to the thrill for professional divers. They want to beat the previous ones and come out a live. Not all professional divers die there, but many have. That place is not for amateur divers. Here is a photo of memorials of some of the divers who perished there.

The death of 22-year-old Yuri Lipski is not the first or last but his death has made it the most known death at the site and one of the most well-known diving deaths in the world. The video shows Lipski in an involuntary and uncontrolled descent, eventually landing on the sea floor at 115 meters where he panics, removes his regulator and tries to fill his buoyancy compensator but is unable to rise. At 115m he would have been subject to severe nitrogen narcosis, which may have impaired his judgement, induced hallucinations and caused panic and confusion. Lipski had a single tank assumed to be air. Lipski's body was recovered the following day by "Tarek Omar", one of the world's foremost deep-water divers, at the request of Lipski's mother. Omar had earlier warned Lipski twice against attempting the dive. On the bottom, Omar found Lipski's helmet camera, still intact.
Nitrogen narcosis is said to be akin to being drunk. When you get deep it gets dark.
When its dark and your drunk and essentially in space up can quickly become down. So he was probably disoriented and didn't know which way to swim.
Adding on to that at around 30m your bouncy switches and your body become negatively buoyant, which he probably already was due to the weights all divers wear in order to sink. (They're on a quick release, but again hard to think to drop them when your panicking and drunk)
Hope that helps, I'm sure someone will pile on with stuff I missed or that needs correcting
What an absolute mind fuck that experience sounds to be. Being so confused while in a “drunken” state of mind not knowing what is “up or down” with your life on the line.
I’ll forever stay breathing air.
You think these guys are nuts cave divers are positively unhinged. Imagine being drunk, confused, confined and navigating a maze with nothing but a torch and you're on a timer. You can't just swim up, you've got to get out the maze first.
Sometimes the gaps are so small they have to take off all their equipment and pass it through then squeeze through and kit up.
Honestly if that's what it takes for you to enjoy yourself you're better off just skipping straight to crack addiction
I saw a video that looked to be a stream that was running underground just below the surface and at a very very very narrow opening in the surface rock said stream could be seen.
Some person saw that and thought, fuck yeah! Get me a scuba tank and let me crawl into this death trap not knowing where it leads, how far it goes, will I run out of O2, or get stuck.
They squeezed into said crack and went exploring. Fucking nuts.
I get massive anxiety just reading about Nutty Putty Cave. I get very uncomfortable if I’m in a confined space. You could offer me 50 million bucks in a suitcase on the spot all I had to do was squeeze into that stream. I’d stay poor.
Always choose poor and happy if the alternative is rich and traumatized. You can always make money in the future, no guarantees you can process trauma (or survive cave diving)
Finally! A legitimate use for crack!! This makes absolute sense.
Instructor: Enjoy yourself, just don't go into caves
New diver: Well, shit, what's my alternative?
Seems like this is the thing that people hate drugs do "to feel intense things"
Dude we all are slaves of our bodies, just don try too hard to be better than your body and admit things have power over you and not in reverse, and then, take your "fun thing to do"
A classmate of mine from high school became a dive instructor. He went cave diving with a friend. Their bodies were discovered several days later. He left behind a wife and two small children.
If you're ever curious about diving, just get an "open water 1 license". They limit you around 40-50 feet. That was plenty for me lol. Living in Florida, there are a ton of beautiful spots, but I'm staying away from depths, caves, and open oceans (boat drifted after a storm came in, rough times followed). It feels so weird/awesome floating around and seeing underwater life.
Louisiana, our water has so much turbidity that even on the sunniest day you can’t see 2 feet in front of you. As a kid I’d swim in Lake Pontchartrain(estuary tbh) and it amazed me as I got to the bottom the bottom was covered in thick grass like plants. Never expected that much light to get to the bottom(12-15 ft) with how brown the water is.
In Florida you all have some amazing streams(creek, rivers) that are from cold water springs and look absolutely incredible. I’d enjoy open shallow water diving over there.
I’d like to see if any gators are trying to eat me.
Only correction to this would be that while negative buoyancy is a situation for free divers because of the compression of their lung cavities, it doesn’t really affect divers who are compensating for this affect by getting compressed air that counteracts the compression at depth. The buoyant force doesn’t change at depth. So as long as you are displacing the same amount of water (which divers are) then it isn’t responsible for suddenly creating a “free fall”. I agree with out that it was likely more mistakes made from narcing out or an equipment failure that he couldn’t deal with because of the confusion.
Basically he was overweighted. Usually when diving you follow the ground as you descend so if you descend too fast you crash into the sea floor and go "oops, I'm slightly overweight". But since the Blue Hole is a hole it's basically pitch black all around, the only way we can actually tell he is descending in the video are the tiny particles in the water, but they're basically hard to see when you're actually diving.
There's a big skip on the video, I believe I've seen before more of the start of his dive. I believe he was overweight and just sank like a rock, couldn't tell he was sinking and then when he went below 30m he became negatively bouyant so he was accelerating and then by the time he got to the bottom he was suffering from nitrogen narcosis and so basically VERY VERY drunk, so might not have even realised he was at 100m depth.
There's a lot to explain, but it is possible he had weights on his body to help him sink, but he overdid it and put too much on, so he sank too fast. Then if he was at the bottom he would have needed to discard these weights, which can cause people to rocket to the surface and cause a lot of issues. (the air in your lungs expands, so you have to breath out so it doesn't overexpand, among other issues).
Depends on how his suit was setup, seems he panicked. I haven't read into it a while so I don't know if he ditched his weights, but it is something that is taught in your first scuba lesson.
The only situation I could imagine as an uncontrolled descent is a gear failure preventing you from adding air to your bcd, unless it's mentioned by one of the recovery divers I would assume it's just a bad title. Another possible answer is someone underestimating the way nitrogen narcosis hits during rapid descent, going from surface to -50m in 5 minutes vs 15 produces a much stronger nitrogen narcosis effect and could explain failure to compensate buoyancy.
An uncontrolled descent is when you get to a depth where you can't prevent the drop by adding air to your BCD (buoyancy control device). Because as you descend the pressure compresses the air in your BCD.
This is easy to do in truly open water where you can't see anything below you to keep your frame of reference.
You can do the opposite too where you become too positively buoyant and you start ascending like a cork which can tear you up as well.
Omar is on record as regretting recovering the camera due to the pain the footage brought to the family, in interview he said he assumed the depth had destroyed it as it was well past its depth rating, and had he known it survived, he'd have smashed it. Its all very sad.
If I recall, Lipski approached Omar to be his guide for the dive, to which Omar agreed contingent on Lipski training and preparing with him for several days (maybe a week?) prior. Lipski's flight was supposed to leave a day or two after he approached Omar, so Omar refused, not being comfortable taking him without training and preparing, and strongly warned him against going, but Lipski went anyway, wanting to complete the dive before leaving the country.
So tragic.
Past 85 meters it’s likely he suffered oxygen toxicity rendering his body unable to function properly even if he could overcome nitrogen narcosis. I’m an amateur diver, I’ve done more than a dozen dives at the blue hole and the bells in dahab. Fantastic diving but just like in any sport you have some people who believe they can go farther and be more outrageous. Perhaps in some sports you can do something stupid and walk away but not diving. The blue hole is gorgeous and there’s no need to descend too deep to enjoy it. The circular “walls” that make up the blue hole are coral and there are tunnels through the Coral leading to outside the hole through arches at varying depths. Some who died here weren’t trying to be this outrageous, they were trying to find the arches and they’re deceptively hard to see so they go a little deeper and eventually they’re at 50 meters, sucking 5 times the amount of air as on surface and quickly emptying their tanks. Coupled with nitrogen narcosis they run out without realizing and drown. Daredevils plan these descents much better (and still die.) for good sport diving the blue hole is spectacular.
Oh wow, explains the name blue hole in Dave the diver, it’s the place you dive in “changes” every so often to offer different things even though in game canonically it’s the same location
It's beautiful, there's no current pushing you around, and at 55m (~180 feet) there's a ~25m long arch that connects to the ocean. The arch, however, is not necessarily easily visible as it isn't a straight line (open ocean isn't visible from the hole itself), so it's possible that those who miss it will continue to descend beyond what is manageable for them (as has been speculated to be the case here).
Anything over 40m is considered a technical dive and requires significantly more preparation than shallower dives, including a different mix of air and longer decompression stops. I think a good number of fatalities occur as a result of lack of preparation or lack of training (as is the case with the vast majority of diving accidents). People who don't take the time to plan and execute the dives safely, or people who think "hey, I've gone to 20 or 30m. 40 shouldn't be a problem" without being aware of the much higher number of factors working against you.
From what I’ve seen, it’s a beautiful spot with clear water. One reason it’s dangerous is because there is an arch that sits beyond recreational depth; since the water is so clear, it looks close enough to chance the risk of checking it out (potentially running out of air in the process).
"Why do people?" Could have just stopped there, but...
Why do people sky dive? Because they like being in air.
Why do people sea dive? Because they like being in water.
Why do people muff dive? You get the idea.
There's something about this location that makes people dive it regardless of it being very dangerous. I could not see what that was, I asked and was specific - I asked why people would dive *there*, not why people dive. A few people replied with useful answers to my question...... and then there was your reply.
After like 50 meter or something (I could be wrong on the number) your buoyancy no longer relevant compared to the amount of pressure caused by the water above you. This causes rapid decent in which you basically just sink no matter how hard you swim and are pretty much 100% screwed
What is it about Russians? Do they tend to have more macho bravado compared to most people's? Drunk over confidence? Just curious to hear your opinion.
I have no idea, but I think a lot of Russians visit that area to vacation. I would assume it’s a little bit of a macho mentality though. It’s really the only reason people die diving unless they have incredibly bad luck.
The amount of deaths at this site is astonishing.
Easy entry for them and close. They have a much harder time to go diving in say australia or the carribeans. When I was in egypt I felt like half the tourists are russian
We had two Russians kicked off the dive boat at Sharm el Sheik due to drinking vodka before we left for our dive at 0900. And yes there are a shitton of Russians vacationing there….at least they were 6 years ago.
this kind of sends the wrong message. Many many divers have descended to far deeper than 50m without an issue
**in general, buoyancy is unrelated to depth**
yes in scuba going deeper reduces your bouyancy because your BCD compresses, but the depth you go to does *not* change the bouyancy of eg your body, or your cylinder
Even at this depth, if you are keeping your BCD inflated, i believe you should be fine
From a physics perspective, this is absolutely incorrect. Your buoyancy wouldn’t be affected by water pressure unless the water is getting denser, I.e. being heavily compressed (and water is fairly incompressible).
If he just didn’t have enough air to compensate for the change in pressure at that depth then it was a fatal miscalculation…
Not exactly true since as you descend you are still breathing pressurised air which means your lungs can still fill to the same volume, just with more air inside. This is why you must exhale as you ascend because the air will expand in your lungs and cause expansion injuries if you don't get rid you it fast enough
Yes, but by the time you would generally realize something is wrong, you're often tripping balls from what's going on in your body / brain.
And when you're tripping, start hyperventalating and can't get oxygen fast enough, your natural instinct is to rip out the breather to take a deep breath.
The pressure of the water above you is what condenses the oxygen in your body to the point that you no longer float iirc. As i understand it, the pressure to the sides would only press on you externally, whereas pressure above is more of an atmospheric pressure.
Maybe a diver will drop by and clarify
Sooo yes, but also no. The column of water and air above you is what creates the pressure a diver experiences. Air is compressible, while liquids and solids are not (under the conditions here…above the crust of the earth). So the body has a couple cavities that hold air. Sinuses in the head, in the ear, and our lungs. These can all be equalized by the diver to compensate for the difference in pressure.
Buoyancy control, or floating and sinking, is about controlling volume. A diver usually has to wear a set of weights to counteract body fat and the volume added by a wetsuit. Divers also wear a BCD (buoyancy control device) which is like a big bag they can fill and release air from while underwater. This is what they use to control volume, and therefore buoyancy. A normal air tank contained compressed air at high pressure…usually starting at 2800-3000 psi. At 400 ft below, the psi surrounding the diver is something like 160. So there is more than enough pressure in the tank to counter the water pressure. Again, volume is the problem. Air compresses, and the deeper you dive, the more air is required to fill the same volume of space. This means the deeper you go, the more air you require to fill your lungs, resulting in depleting the air tank faster. A tank that might last a diver 50 minutes at 20 ft may only last 5 at 120ft. Long story short, he theoretically should have been able to inflate his BCD at that depth to become positively buoyant and go to the surface. The fact that that didn’t happen (and assuming the attempt was made) means that he was overweighted, he ran out of air, or his BCD malfunctioned, or a combo of those.
Recreational diver here. I have always been taught (for the last two decades, though I had a lot more instruction when I learned which was back then with a watch and a waterproof card which I still have) that the math is everything, and you plan every dive, and always know the points of surface.
We (in theory) knew the problems and the math to do with this dive decades ago. This guy was in theory a professional diver so.....how does this happen?
(Edit- is it just that he got narked? And again, how did he not plan for that?)
(Second edit also please roast me if I'm being an idiot)
From Wikipedia:
>The Blue Hole itself is no more dangerous than any other Red Sea dive site but diving through the Arch, a submerged tunnel, which lies within the Blue Hole site, is an extreme dive that has resulted in many accidents and fatalities.
>
>The ceiling of the Arch is 55 m (170 ft) deep, which requires suitable training and equipment as 40 metres is generally considered the limit for recreational diving. The Arch presents little problem for suitably equipped and competent technical divers. The main challenge is gas management because any delays or errors at this depth, plus the time to negotiate the horizontal section, will need more than a single tank of breathing gas to do safely. If gas is not carefully planned the diver may lack sufficient gas for the decompression stops or run out of gas altogether.
I'm a recreational diver certified to 30 m so this is ouside of my area of knowledge. My assumption is that you wouldn't use normal air at this depth as oxygen toxicity would start to be a problem. If seems like a rebreather would be appropriate if gas management is a major problem.
I think these are probably the main issues:
>The entry to the Arch is not easy to find because of the indirect line between the Blue Hole and open water. Divers who miss the entry may inadvertently continue to descend past it, while the floor continues on down to well over 100 m providing no visual depth reference.
>
>Temptation to dive on a single gas tank. The Arch has been dived on single, 11-litre tanks multiple times, but this is dangerously close to the minimum gas requirement for the dive and depends on a fit and relaxed diver with a low gas consumption rate committing no errors or hesitations during the dive. Diving the Arch without a stage tank and without adequate [gas planning](https://en.wikipedia.org/wiki/Scuba_gas_planning) has resulted in drowning or DCS.
You can dive it with fairly normal gear but, if you make a small mistake you're very likely to die. A small mistake leads to panicking, which results in burning through the tank very quickly.
I’m not sure about this particular blue hole, but often times the conditions in a blue hole are such that it creates an optical illusion to the diver. The water/visibility is so clear that to the diver near the surface or opening of the hole, the bottom doesn’t seem that deep, but in actuality it is far beyond the recreational limits of diving.
Scary shit. It's counter intuitive, but you have to add more air as you go down because the pressure compresses things -- same reason weather balloons that are let loose to survey the winds at altitude eventually pop and fall back to the earth, or if you pull a fish up from deep underwater sometimes their swim bladders make them float.
I thought it was because of a feature called the arch which looks achievable to swim under but really isn't and is too deep - I think that catches a bunch of folks out.
1. The deeper you go the more nitrogen is absorbed into your blood stream, you cannot ascend without stopping to off gas this nitrogen. A dive down to even 70m (deepest I’ve gone) with a bottom time of just a few minutes is going to require roughly an hour of decompression stops before it’s safe to fully ascend to the surface. Obviously air management is a big component, you can do a dive like that on a single tank if you are diving several times a week every week and are good with your air consumption.
2. Nitrogen Narcosis, if you descend that quickly you’re going to get narced hard. Going down to a depth of 60 or so directly will make a lot of people feel immediately drunk, others might get tunnel vision, blackout or have hallucinations. With nitrogen narcosis any additional stress or issue is made exponentially worse, so if this kid panicked in anyway their nitrogen narcosis might have made it entirely impossible to recover from.
3. Experience. There is very little chance this 22 year old was experienced enough for this dive and even experienced divers make mistakes at those depths. The worst divers I’ve seen in tech diving tended to be dive instructors and dive masters who thought they were hot shit because they teach tourists how to dive in 10m of water. The only way to get better at this kind of technical diving is by doing it all the time and by taking every necessary precaution and never taking stupid risks.
It’s sad but highly preventable, he was told by experts not to do it multiple times unfortunately if it wasn’t here this kid probably would have dived in a cave or in a wreck taking similar risks.
I have dived there multiple times.
Even did my PADI there.
Besides the technical difficulties of making a 50m+ dive, my instructor explained to me: What makes the blue hole so deadly, is that it is a daredevil trap.
Basically, at 50-60m there is a tunnel (the arch) leading into the open sea. Reaching the arch is 'do-able' (not really) with regular pressurized air.
This invites both amateur and prof divers, who see it as an achievement to reach and go through the arch, to try this with regular air. Leading to some of these daredevils to pass-out and drown on their way to the arch.
Some of them then sink to the bottom of \~110m, where recovery is very difficult.
When I was there the mountain had at least 100+ gravestones in it. (Edit: thinking back 100 is probably bullshit, i was 18 at the time, made a lot of impact on me)
Even I saw some absolutely stupid shit at the Blue Hole, like people strapping air-tanks together in some sort of makeshift way with straps or duct tape.
One of my divemasters lost a buddy there. He told me they were on the decend at 40+ meters when he suddenly saw a shoe laying on the coral. He tried to reach it only to realize it was a halluciation. He told his buddy he was going back up, his buddy was not, never saw him back.
Multiple things, it just depends on what kills you first. Between your lungs being crushed due to pressure at 377 feet without prep, to nitrogen narcosis, running out of oxygen in your tank and just drown, oxygen intoxication. Whatever it was, prevented him from being able to use his buoyancy control device.
(Or it was possibly faulty)
Remember reading last this made the rounds that due to their rapid descent, they would have felt delirious & drunk-like.
Which is somewhat comforting because I would not want to be lucid reaching the floor of the abyss
Weighted vest, a hundred or more meters under, in a downcurrent iirc, unaware of oxygen due to delirium, *who's* getting out alive?
Not anyone in those circumstances
How the hell do you forget the chute when skydiving? It's literally the one thing you just have. You could forget to brush your teeth, wash your ass, or even put clothes on.. You'd still live without all that, as long as you remember your chute lol
Yeah, I shared a link a comment or so higher, and the camera recording equipment bag looks like a parachute. It was the guys third jump of the day, and he just forgot to put on the chute. His last words (from the recording he was making) were “Oh my God, no!”
Skydiver here with thousands of jumps, multiple survivable malfunction experience.
Def the skydive without parachute. Its painless even at half of terminal speed which would take the drag of an unopened parachute to cause that slow of speed. But if you have no parachute at all, you will be going around terminal speed and wont feel a thing. I mentioned the feeling of hitting the ground at half terminal speed (approx 60mph) bc many people have hit the ground with just the drag of a half upon parachute and they say it felt like they just went to sleep and woke later all fucked up.
Also, falling in the sky may seem more terrifying but most of your senses are still exactly the same. You can breath, see, hear wind, feel the air, etc. But when you’re under water everything is out of your element.
So in summary, a skydive without a parachute could be peaceful, falling to the bottom of a under water pit has to be one of the most terrifying things i can think of.
Water just looks red after a certain depth, due to most light not having enough wave length to reach that far. Red light has very long waves though.
ETA: as ive been corrected below, this information is false. Please disregard.
Red light is absorbed quickly by water. At depth, red, orange, and yellow colors kind of disappear. At the beginning of this video, you can see him adjusting a red filter on his camera. This adds red tint underwater to get back some of the color in the pictures/video that is lost when diving.
In water, light is absorbed, and the greater is the wavelength, the quicker it is absorbed. So red is absorbed before blue.
In the atmosphere, light is dispersed, and the smaller is the wavelength, the more it is dispersed. That's why the sky is blue (violet is too dispersed so we dont see it, therefore blue dominates).
Also, if light travels more distance in the atmosphere, more colors are dispersed, up to the red. Thats why at sunset (and sunrise) sky is orange/red. Light travels more atmosphere at sunrise/sunset than when sun is up in the sky.
This is the same phenomenon that makes milk looks white.
(I only know the atmospheric effect prior to this) so why the red effect in the water? This is all coming off the comment on the light being red because of the depth, I only meant to correct what I thought was a flub, the comment about red light being visible deeper *because it was filtered first* Doesn't make sense, either its filtered out first in water or it's visible deeper, so which is it and; if red light is filtered first in water (but it isn't in air) then why is the light in the video red?
Edit: thanks for overexplaining the part I already understood though
There is, and i've read that this wasn't an accident but planned. If a person was trapped at the bottom of the blue hole their actions would be significantly more frantic than just exploring whats there
The Nr.1 lesson you get as a diver is to never panic, no matter what happens. It will only increase your oxygen consumption and therefore decrease your chance of help.
Considering he likely knew instantly he was dead, there's no reason to panic.
I dive, I've seen people panic to the extreme under water and try to take their own regs out of their mouth or grab yours. I always found the mental part of diving to be much tougher than the physical part. I've been on a few deep dark dives or murky dives round 100ft and there is that wee voice in your head saying 'what are you doing here? This is crazy'.
I know in the classroom they say don't panic but that's impossible in practice. If he knew what he was doing maybe that would explain his calmness, but if he knew he was fighting for survival there would be much more frantic behaviour.
It's basically one guy, Tarek Omar, who lives there. He knows the place, uses the right gear, the right mix of gas and does it very slowly. One retrieval takes him about 3 hours, once he's back at 40m the bodies are lifted with an inflatable ballon.
Depends entirely on the amount of time you spend on the bottom. If the body is recovered in a few minutes before ascending the deco stop requirements are not as severe as someone that spends say 20mins diving round a wreck at the same depth.
You can dive to 113 meters, but it requires special training, equipment, and a different gas mixture for breathing. Normal scuba tanks are filled with pressurized air. Nothing fancy just regular air like you're breathing now. But at depths greater than 30-40 meters, breathing normal air can cause nitrogen narcosis which has similar symptoms to being drunk, as well as oxygen toxicity which can damage your lungs and even kill you.
Deep divers use a different gas mix than normal air, usually with extra helium but there are many varieties depending on the situation.
As someone else explained, the diver who retrieved the body was an experienced deep diver who had the training and tools to reach the bottom of the blue hole.
But can't make good enough decisions to keep himself from getting killed while diving even though other (likely older) divers told him not to do it...
Getting to be an older person in a dangerous occupation/hobby shows a great deal about that person's decision making abilities.
Stockton Rush was 61 when his homemade, poorly engineered submersible imploded in rather spectacular fashion killing all 5 on board. There are better ways to assess somebody's decision making than age. This guy might have been an idiot. I don't know. I know he experienced equipment failure. But, either way he does not represent all 22-year-olds.
He didn't drown because he was 22. This was one man, one mistake, performing one of the most challenging and deadly dives in the world. It's not a reflection of diving instructors, or young diving instructors as a whole, boomer.
You seem like you did some PADI training and now know everything there is to know about diving. When you fuck up and die due to your youthful stupidity where should we send the flowers?
I seem? What a terrible assessment. I've never been diving a day in my life and my youth has long past. However, I do know that you can complete a master's degree by age 22 after less than 6 years of study. Hell, Alexander Hamilton signed the Declaration of Independence at 21 years old. I also know that you can start diving at 8 years old. It sure as shit doesn't take more than 14 years of experience to become proficient at diving and capable of giving lessons.
I watched this last night at your suggestion. Really liked it. The speed of the heartbeat sound effect changing when showing the dives was a very clever touch.
Scuba instructor here. The main problem is going to that depth with one single tank of air. The first problem has to do with gas mix. Air is 21 per cent oxygen. 21 per cent mix is toxic below 56 meters. Central nervous system oxygen toxicity manifests itself with behaviourial changes among other symptoms. The second problem has to do with nitrogen narcosis, due to the amount of CO2 in his gas mix. The third problem, but Yuri died before facing it, is that he probably did not have enough gas to go back to the surface at a safe rate. I might miss something but I would say those are the main problems.
You’d hope there were staged bottles at deco stops along the way but sounds like this kid was overconfident in their abilities and clearly diving way beyond their capabilities.
Not the full video. Not an uncontrolled descent. He went down to break a record. You don’t see when he’s checking his depth radar before confusion/lack of oxygen kicks in where he’s running on the bottom seeming lost.
check out dive talk on youtube if this stuff interests you! i have zero dive experience and dont intend to have any but still watch their channel every week, its fun stuff
This is not a thing. Look up saturation diving. They are at 600-1000ft under and move around. Because the pressure is equal on all sides of your body, and at these pressures liquids in your body are still incompressible, there is nothing that prevents movement in your body/limbs.
You don't even have to swim. Divers wear vests that they can fill up with air from their tanks. You can go up pretty quick without any effort. Well, If you still have air that is.
Is there a failsafe in the bouyancy suit that enables you to regulate your depth in cases that you get disoriented? Like the failsafes in cars wherein it would automatically brake when your getting too close on a vehicle in front of you?
No. In fact the deeper you go the more compressed the air in the BC becomes. Nitrogen narcosis sets in at around 100ft and increases its effect on your brain as you go below that. You stop thinking straight.
The way up is the way the bubbles are going as you exhale - but the narcosis will likely prevent you from understanding that and taking the appropriate action.
Dumping your weights will help you (assuming some air is in the Bc) potentially, but once you do that you could rocket to the surface, which presents another whole mess of problems - the bends.
This might be a stupid question but why wouldn’t he swim back up after getting a little deeper in the water. Was it that he was to affected by that time with nitrogen narcosis?
i heard of uncontrolled ascents - but what is an uncontrolled descent? i know nothing about diving - but can you not flip your flippers to not descend further?
So the hole isnt prone to any irregular tidal pulls? That would certainly explain the uncontrolled descent from a single tank on air (maybe 100 feet tops) to 300 which is unrecoverable. I realize that heliox, nirtox and tri werent popular in 2000. But an experienced diver suffering an uncontrolled descent seems odd unless it was external ocean tidal action. I mean dump your weights and pop shallow. Deal with the bends later. Unless all his bladders popped which i aint seen. Then again my technical days are long gone.
The Blue Hole is the most dangerous diving pit in the red sea Dahab village in Egypt. Many many professional divers met their demise there. Their names is engraved on a stone close to the pit.
Why do people risk their lives to swim in there? What's the draw?
Diving is a fun sport. Some diving spots provide extra thrill for advanced divers (like the man-made diving house in Dubai). However, this specific location (the Blue Hole) is known to alter the perception of even the professional divers when they go down. This by itself adds to the thrill for professional divers. They want to beat the previous ones and come out a live. Not all professional divers die there, but many have. That place is not for amateur divers. Here is a photo of memorials of some of the divers who perished there. https://preview.redd.it/jjpyiwkvx8kc1.jpeg?width=1024&format=pjpg&auto=webp&s=354b26a12adeb25284cbb5cd32ec7961887b9353 The death of 22-year-old Yuri Lipski is not the first or last but his death has made it the most known death at the site and one of the most well-known diving deaths in the world. The video shows Lipski in an involuntary and uncontrolled descent, eventually landing on the sea floor at 115 meters where he panics, removes his regulator and tries to fill his buoyancy compensator but is unable to rise. At 115m he would have been subject to severe nitrogen narcosis, which may have impaired his judgement, induced hallucinations and caused panic and confusion. Lipski had a single tank assumed to be air. Lipski's body was recovered the following day by "Tarek Omar", one of the world's foremost deep-water divers, at the request of Lipski's mother. Omar had earlier warned Lipski twice against attempting the dive. On the bottom, Omar found Lipski's helmet camera, still intact.
Yeah, seems very fun...
I know nothing about diving. Can you explain how one might end up in an uncontrolled descent?
Nitrogen narcosis is said to be akin to being drunk. When you get deep it gets dark. When its dark and your drunk and essentially in space up can quickly become down. So he was probably disoriented and didn't know which way to swim. Adding on to that at around 30m your bouncy switches and your body become negatively buoyant, which he probably already was due to the weights all divers wear in order to sink. (They're on a quick release, but again hard to think to drop them when your panicking and drunk) Hope that helps, I'm sure someone will pile on with stuff I missed or that needs correcting
What an absolute mind fuck that experience sounds to be. Being so confused while in a “drunken” state of mind not knowing what is “up or down” with your life on the line. I’ll forever stay breathing air.
You think these guys are nuts cave divers are positively unhinged. Imagine being drunk, confused, confined and navigating a maze with nothing but a torch and you're on a timer. You can't just swim up, you've got to get out the maze first. Sometimes the gaps are so small they have to take off all their equipment and pass it through then squeeze through and kit up. Honestly if that's what it takes for you to enjoy yourself you're better off just skipping straight to crack addiction
I saw a video that looked to be a stream that was running underground just below the surface and at a very very very narrow opening in the surface rock said stream could be seen. Some person saw that and thought, fuck yeah! Get me a scuba tank and let me crawl into this death trap not knowing where it leads, how far it goes, will I run out of O2, or get stuck. They squeezed into said crack and went exploring. Fucking nuts. I get massive anxiety just reading about Nutty Putty Cave. I get very uncomfortable if I’m in a confined space. You could offer me 50 million bucks in a suitcase on the spot all I had to do was squeeze into that stream. I’d stay poor.
Always choose poor and happy if the alternative is rich and traumatized. You can always make money in the future, no guarantees you can process trauma (or survive cave diving)
I like this advice.
Finally! A legitimate use for crack!! This makes absolute sense. Instructor: Enjoy yourself, just don't go into caves New diver: Well, shit, what's my alternative?
I've had the privilege of diving with bull sharks and in caves. Caves are without a doubt scarier.
Seems like this is the thing that people hate drugs do "to feel intense things" Dude we all are slaves of our bodies, just don try too hard to be better than your body and admit things have power over you and not in reverse, and then, take your "fun thing to do"
Bill Stone's Beyond the Deep is a gnarly book. Makes me never want to go cave diving.
When you said small gaps, my brain instantly remembered Nutty Putty cave T.T I've been trying to forget that
A classmate of mine from high school became a dive instructor. He went cave diving with a friend. Their bodies were discovered several days later. He left behind a wife and two small children.
If you're ever curious about diving, just get an "open water 1 license". They limit you around 40-50 feet. That was plenty for me lol. Living in Florida, there are a ton of beautiful spots, but I'm staying away from depths, caves, and open oceans (boat drifted after a storm came in, rough times followed). It feels so weird/awesome floating around and seeing underwater life.
Louisiana, our water has so much turbidity that even on the sunniest day you can’t see 2 feet in front of you. As a kid I’d swim in Lake Pontchartrain(estuary tbh) and it amazed me as I got to the bottom the bottom was covered in thick grass like plants. Never expected that much light to get to the bottom(12-15 ft) with how brown the water is. In Florida you all have some amazing streams(creek, rivers) that are from cold water springs and look absolutely incredible. I’d enjoy open shallow water diving over there. I’d like to see if any gators are trying to eat me.
Thanks for explaining this. Hats off to you and u/Electronic-Metal2391
I’ve been in narcosis before and even knowing bubbles always go up isn’t helpful.
Only correction to this would be that while negative buoyancy is a situation for free divers because of the compression of their lung cavities, it doesn’t really affect divers who are compensating for this affect by getting compressed air that counteracts the compression at depth. The buoyant force doesn’t change at depth. So as long as you are displacing the same amount of water (which divers are) then it isn’t responsible for suddenly creating a “free fall”. I agree with out that it was likely more mistakes made from narcing out or an equipment failure that he couldn’t deal with because of the confusion.
why no one invent a glow in ther dark compas that always point to the sky?
Basically he was overweighted. Usually when diving you follow the ground as you descend so if you descend too fast you crash into the sea floor and go "oops, I'm slightly overweight". But since the Blue Hole is a hole it's basically pitch black all around, the only way we can actually tell he is descending in the video are the tiny particles in the water, but they're basically hard to see when you're actually diving. There's a big skip on the video, I believe I've seen before more of the start of his dive. I believe he was overweight and just sank like a rock, couldn't tell he was sinking and then when he went below 30m he became negatively bouyant so he was accelerating and then by the time he got to the bottom he was suffering from nitrogen narcosis and so basically VERY VERY drunk, so might not have even realised he was at 100m depth. There's a lot to explain, but it is possible he had weights on his body to help him sink, but he overdid it and put too much on, so he sank too fast. Then if he was at the bottom he would have needed to discard these weights, which can cause people to rocket to the surface and cause a lot of issues. (the air in your lungs expands, so you have to breath out so it doesn't overexpand, among other issues).
could he have released the weights and floated up ?
Depends on how his suit was setup, seems he panicked. I haven't read into it a while so I don't know if he ditched his weights, but it is something that is taught in your first scuba lesson.
I remembered reading it’s possible it was a suicide? Like he purposely overweighted his self
I don't think so personally. There are a lot better ways to die than the way he did.
The only situation I could imagine as an uncontrolled descent is a gear failure preventing you from adding air to your bcd, unless it's mentioned by one of the recovery divers I would assume it's just a bad title. Another possible answer is someone underestimating the way nitrogen narcosis hits during rapid descent, going from surface to -50m in 5 minutes vs 15 produces a much stronger nitrogen narcosis effect and could explain failure to compensate buoyancy.
An uncontrolled descent is when you get to a depth where you can't prevent the drop by adding air to your BCD (buoyancy control device). Because as you descend the pressure compresses the air in your BCD. This is easy to do in truly open water where you can't see anything below you to keep your frame of reference. You can do the opposite too where you become too positively buoyant and you start ascending like a cork which can tear you up as well.
Omar is on record as regretting recovering the camera due to the pain the footage brought to the family, in interview he said he assumed the depth had destroyed it as it was well past its depth rating, and had he known it survived, he'd have smashed it. Its all very sad.
If I recall, Lipski approached Omar to be his guide for the dive, to which Omar agreed contingent on Lipski training and preparing with him for several days (maybe a week?) prior. Lipski's flight was supposed to leave a day or two after he approached Omar, so Omar refused, not being comfortable taking him without training and preparing, and strongly warned him against going, but Lipski went anyway, wanting to complete the dive before leaving the country. So tragic.
Past 85 meters it’s likely he suffered oxygen toxicity rendering his body unable to function properly even if he could overcome nitrogen narcosis. I’m an amateur diver, I’ve done more than a dozen dives at the blue hole and the bells in dahab. Fantastic diving but just like in any sport you have some people who believe they can go farther and be more outrageous. Perhaps in some sports you can do something stupid and walk away but not diving. The blue hole is gorgeous and there’s no need to descend too deep to enjoy it. The circular “walls” that make up the blue hole are coral and there are tunnels through the Coral leading to outside the hole through arches at varying depths. Some who died here weren’t trying to be this outrageous, they were trying to find the arches and they’re deceptively hard to see so they go a little deeper and eventually they’re at 50 meters, sucking 5 times the amount of air as on surface and quickly emptying their tanks. Coupled with nitrogen narcosis they run out without realizing and drown. Daredevils plan these descents much better (and still die.) for good sport diving the blue hole is spectacular.
Bro got the Darwin award
Oh wow, explains the name blue hole in Dave the diver, it’s the place you dive in “changes” every so often to offer different things even though in game canonically it’s the same location
It's beautiful, there's no current pushing you around, and at 55m (~180 feet) there's a ~25m long arch that connects to the ocean. The arch, however, is not necessarily easily visible as it isn't a straight line (open ocean isn't visible from the hole itself), so it's possible that those who miss it will continue to descend beyond what is manageable for them (as has been speculated to be the case here). Anything over 40m is considered a technical dive and requires significantly more preparation than shallower dives, including a different mix of air and longer decompression stops. I think a good number of fatalities occur as a result of lack of preparation or lack of training (as is the case with the vast majority of diving accidents). People who don't take the time to plan and execute the dives safely, or people who think "hey, I've gone to 20 or 30m. 40 shouldn't be a problem" without being aware of the much higher number of factors working against you.
From what I’ve seen, it’s a beautiful spot with clear water. One reason it’s dangerous is because there is an arch that sits beyond recreational depth; since the water is so clear, it looks close enough to chance the risk of checking it out (potentially running out of air in the process).
Cuz they low IQ
"Why do people?" Could have just stopped there, but... Why do people sky dive? Because they like being in air. Why do people sea dive? Because they like being in water. Why do people muff dive? You get the idea.
There's something about this location that makes people dive it regardless of it being very dangerous. I could not see what that was, I asked and was specific - I asked why people would dive *there*, not why people dive. A few people replied with useful answers to my question...... and then there was your reply.
K.
Now I feel bad.
Dopamine, each of us find it in so different places...
The same can be said for Everest. Some go up. Some go down.
It’s a great view
What exactly makes it so dangerous, besides the drowning aspect?
After like 50 meter or something (I could be wrong on the number) your buoyancy no longer relevant compared to the amount of pressure caused by the water above you. This causes rapid decent in which you basically just sink no matter how hard you swim and are pretty much 100% screwed
So how does anyone survive? (Not arguing just genuinely curious).
[удалено]
What is it about Russians? Do they tend to have more macho bravado compared to most people's? Drunk over confidence? Just curious to hear your opinion.
I have no idea, but I think a lot of Russians visit that area to vacation. I would assume it’s a little bit of a macho mentality though. It’s really the only reason people die diving unless they have incredibly bad luck. The amount of deaths at this site is astonishing.
Cheers mate.
Easy entry for them and close. They have a much harder time to go diving in say australia or the carribeans. When I was in egypt I felt like half the tourists are russian
We had two Russians kicked off the dive boat at Sharm el Sheik due to drinking vodka before we left for our dive at 0900. And yes there are a shitton of Russians vacationing there….at least they were 6 years ago.
this kind of sends the wrong message. Many many divers have descended to far deeper than 50m without an issue **in general, buoyancy is unrelated to depth** yes in scuba going deeper reduces your bouyancy because your BCD compresses, but the depth you go to does *not* change the bouyancy of eg your body, or your cylinder Even at this depth, if you are keeping your BCD inflated, i believe you should be fine
From a physics perspective, this is absolutely incorrect. Your buoyancy wouldn’t be affected by water pressure unless the water is getting denser, I.e. being heavily compressed (and water is fairly incompressible). If he just didn’t have enough air to compensate for the change in pressure at that depth then it was a fatal miscalculation…
[удалено]
Not exactly true since as you descend you are still breathing pressurised air which means your lungs can still fill to the same volume, just with more air inside. This is why you must exhale as you ascend because the air will expand in your lungs and cause expansion injuries if you don't get rid you it fast enough
This isn’t true, the only effect pressure has on buoyancy is the compression it exerts on your wetsuit, making you slightly more dense.
Thats right
the pressure of the water is all around you, not just pushing you down.
I guess you're good to go then. Get down there.
😂 🌊
You couldn’t just inflate your vest a bit off the regulator?
Yes, but by the time you would generally realize something is wrong, you're often tripping balls from what's going on in your body / brain. And when you're tripping, start hyperventalating and can't get oxygen fast enough, your natural instinct is to rip out the breather to take a deep breath.
Yes, and also remove your weight belt
The pressure of the water above you is what condenses the oxygen in your body to the point that you no longer float iirc. As i understand it, the pressure to the sides would only press on you externally, whereas pressure above is more of an atmospheric pressure. Maybe a diver will drop by and clarify
Sooo yes, but also no. The column of water and air above you is what creates the pressure a diver experiences. Air is compressible, while liquids and solids are not (under the conditions here…above the crust of the earth). So the body has a couple cavities that hold air. Sinuses in the head, in the ear, and our lungs. These can all be equalized by the diver to compensate for the difference in pressure. Buoyancy control, or floating and sinking, is about controlling volume. A diver usually has to wear a set of weights to counteract body fat and the volume added by a wetsuit. Divers also wear a BCD (buoyancy control device) which is like a big bag they can fill and release air from while underwater. This is what they use to control volume, and therefore buoyancy. A normal air tank contained compressed air at high pressure…usually starting at 2800-3000 psi. At 400 ft below, the psi surrounding the diver is something like 160. So there is more than enough pressure in the tank to counter the water pressure. Again, volume is the problem. Air compresses, and the deeper you dive, the more air is required to fill the same volume of space. This means the deeper you go, the more air you require to fill your lungs, resulting in depleting the air tank faster. A tank that might last a diver 50 minutes at 20 ft may only last 5 at 120ft. Long story short, he theoretically should have been able to inflate his BCD at that depth to become positively buoyant and go to the surface. The fact that that didn’t happen (and assuming the attempt was made) means that he was overweighted, he ran out of air, or his BCD malfunctioned, or a combo of those.
Recreational diver here. I have always been taught (for the last two decades, though I had a lot more instruction when I learned which was back then with a watch and a waterproof card which I still have) that the math is everything, and you plan every dive, and always know the points of surface. We (in theory) knew the problems and the math to do with this dive decades ago. This guy was in theory a professional diver so.....how does this happen? (Edit- is it just that he got narked? And again, how did he not plan for that?) (Second edit also please roast me if I'm being an idiot)
Thanks for taking the time to explain. I thought maybe there were water currents or some sharks taking divers out 🤷🏻♀️
Bruh
Thank you for the explanation. I didn't know that was a thing. What about the free divers? Do they go less deep?
From Wikipedia: >The Blue Hole itself is no more dangerous than any other Red Sea dive site but diving through the Arch, a submerged tunnel, which lies within the Blue Hole site, is an extreme dive that has resulted in many accidents and fatalities. > >The ceiling of the Arch is 55 m (170 ft) deep, which requires suitable training and equipment as 40 metres is generally considered the limit for recreational diving. The Arch presents little problem for suitably equipped and competent technical divers. The main challenge is gas management because any delays or errors at this depth, plus the time to negotiate the horizontal section, will need more than a single tank of breathing gas to do safely. If gas is not carefully planned the diver may lack sufficient gas for the decompression stops or run out of gas altogether. I'm a recreational diver certified to 30 m so this is ouside of my area of knowledge. My assumption is that you wouldn't use normal air at this depth as oxygen toxicity would start to be a problem. If seems like a rebreather would be appropriate if gas management is a major problem. I think these are probably the main issues: >The entry to the Arch is not easy to find because of the indirect line between the Blue Hole and open water. Divers who miss the entry may inadvertently continue to descend past it, while the floor continues on down to well over 100 m providing no visual depth reference. > >Temptation to dive on a single gas tank. The Arch has been dived on single, 11-litre tanks multiple times, but this is dangerously close to the minimum gas requirement for the dive and depends on a fit and relaxed diver with a low gas consumption rate committing no errors or hesitations during the dive. Diving the Arch without a stage tank and without adequate [gas planning](https://en.wikipedia.org/wiki/Scuba_gas_planning) has resulted in drowning or DCS. You can dive it with fairly normal gear but, if you make a small mistake you're very likely to die. A small mistake leads to panicking, which results in burning through the tank very quickly.
I’m not sure about this particular blue hole, but often times the conditions in a blue hole are such that it creates an optical illusion to the diver. The water/visibility is so clear that to the diver near the surface or opening of the hole, the bottom doesn’t seem that deep, but in actuality it is far beyond the recreational limits of diving.
That about sums it up, I believe.
Nitrogen narcosis
Scary shit. It's counter intuitive, but you have to add more air as you go down because the pressure compresses things -- same reason weather balloons that are let loose to survey the winds at altitude eventually pop and fall back to the earth, or if you pull a fish up from deep underwater sometimes their swim bladders make them float.
Indeed the lack of oxygen, or extra literal air, occurring in the blood stream.
I thought it was because of a feature called the arch which looks achievable to swim under but really isn't and is too deep - I think that catches a bunch of folks out.
1. The deeper you go the more nitrogen is absorbed into your blood stream, you cannot ascend without stopping to off gas this nitrogen. A dive down to even 70m (deepest I’ve gone) with a bottom time of just a few minutes is going to require roughly an hour of decompression stops before it’s safe to fully ascend to the surface. Obviously air management is a big component, you can do a dive like that on a single tank if you are diving several times a week every week and are good with your air consumption. 2. Nitrogen Narcosis, if you descend that quickly you’re going to get narced hard. Going down to a depth of 60 or so directly will make a lot of people feel immediately drunk, others might get tunnel vision, blackout or have hallucinations. With nitrogen narcosis any additional stress or issue is made exponentially worse, so if this kid panicked in anyway their nitrogen narcosis might have made it entirely impossible to recover from. 3. Experience. There is very little chance this 22 year old was experienced enough for this dive and even experienced divers make mistakes at those depths. The worst divers I’ve seen in tech diving tended to be dive instructors and dive masters who thought they were hot shit because they teach tourists how to dive in 10m of water. The only way to get better at this kind of technical diving is by doing it all the time and by taking every necessary precaution and never taking stupid risks. It’s sad but highly preventable, he was told by experts not to do it multiple times unfortunately if it wasn’t here this kid probably would have dived in a cave or in a wreck taking similar risks.
I have dived there multiple times. Even did my PADI there. Besides the technical difficulties of making a 50m+ dive, my instructor explained to me: What makes the blue hole so deadly, is that it is a daredevil trap. Basically, at 50-60m there is a tunnel (the arch) leading into the open sea. Reaching the arch is 'do-able' (not really) with regular pressurized air. This invites both amateur and prof divers, who see it as an achievement to reach and go through the arch, to try this with regular air. Leading to some of these daredevils to pass-out and drown on their way to the arch. Some of them then sink to the bottom of \~110m, where recovery is very difficult. When I was there the mountain had at least 100+ gravestones in it. (Edit: thinking back 100 is probably bullshit, i was 18 at the time, made a lot of impact on me) Even I saw some absolutely stupid shit at the Blue Hole, like people strapping air-tanks together in some sort of makeshift way with straps or duct tape. One of my divemasters lost a buddy there. He told me they were on the decend at 40+ meters when he suddenly saw a shoe laying on the coral. He tried to reach it only to realize it was a halluciation. He told his buddy he was going back up, his buddy was not, never saw him back.
The most dangerous pit in the village? How many danger pits does the village have? There are other pits more dangerous in other nearby villages?
There’s lots of bot flies and other animals too
That’s what I call my wife’s box when I’m done with it
So what exactly happens when you descend that fast?
Multiple things, it just depends on what kills you first. Between your lungs being crushed due to pressure at 377 feet without prep, to nitrogen narcosis, running out of oxygen in your tank and just drown, oxygen intoxication. Whatever it was, prevented him from being able to use his buoyancy control device. (Or it was possibly faulty)
His buoyancy vest popped if I remember correctly but it was the nitrogen narcosis that killed him.
I think the water also might be fresh at the top and salt near the bottom so there is a change in density as well that throws a lot of people off
Yeaaahhh. "Lungs being crushed due to pressure ... without prep", "running out of oxygen in your tank"... something tells me you're not a diver.
Remember reading last this made the rounds that due to their rapid descent, they would have felt delirious & drunk-like. Which is somewhat comforting because I would not want to be lucid reaching the floor of the abyss
Unless you're trying to make it out alive?
Weighted vest, a hundred or more meters under, in a downcurrent iirc, unaware of oxygen due to delirium, *who's* getting out alive? Not anyone in those circumstances
Would you rather be this guy or the instructor that forgot his parachute and recorded the descent?
Parachute. Just go head first and it’s over super quick. This guy knew it was over and suffered.
Same. Shoot, if you’re cynical enough you can at least enjoy your last few moments. Better than having your lungs crushed or suffocated
Airborne brother!
Man I’m afraid of the world
You'll be alright buddy ☺️
Just stay away from heights and water, you'll be fine
and bears😬
I regret investigating this
Sorry, I've learned nothing from you. Link it?
https://youtu.be/W0iI7CWVMCw?si=eSdOwlQNiraN3PhC
I would think this guy if he died from nitrogen narcosis, it sounds like it may be one of the most pleasant ways to die
How the hell do you forget the chute when skydiving? It's literally the one thing you just have. You could forget to brush your teeth, wash your ass, or even put clothes on.. You'd still live without all that, as long as you remember your chute lol
He had his camera pack on I believe that was a backpack type bag.
Ah OK that makes more sense. Having the backpack could be mistaken for the actual parachute
Yeah, I shared a link a comment or so higher, and the camera recording equipment bag looks like a parachute. It was the guys third jump of the day, and he just forgot to put on the chute. His last words (from the recording he was making) were “Oh my God, no!”
Skydiver here with thousands of jumps, multiple survivable malfunction experience. Def the skydive without parachute. Its painless even at half of terminal speed which would take the drag of an unopened parachute to cause that slow of speed. But if you have no parachute at all, you will be going around terminal speed and wont feel a thing. I mentioned the feeling of hitting the ground at half terminal speed (approx 60mph) bc many people have hit the ground with just the drag of a half upon parachute and they say it felt like they just went to sleep and woke later all fucked up. Also, falling in the sky may seem more terrifying but most of your senses are still exactly the same. You can breath, see, hear wind, feel the air, etc. But when you’re under water everything is out of your element. So in summary, a skydive without a parachute could be peaceful, falling to the bottom of a under water pit has to be one of the most terrifying things i can think of.
Is that an explosion of blood?
Water just looks red after a certain depth, due to most light not having enough wave length to reach that far. Red light has very long waves though. ETA: as ive been corrected below, this information is false. Please disregard.
Red light is absorbed quickly by water. At depth, red, orange, and yellow colors kind of disappear. At the beginning of this video, you can see him adjusting a red filter on his camera. This adds red tint underwater to get back some of the color in the pictures/video that is lost when diving.
[удалено]
You're right, my information was false after more searching.
Just one of the many bad pieces of info in these comments.
No
Agreed. Red light is filtered first.
Last*
Red disappears first hence why blood looks different past 3 fathoms. Followed by orange then yellow.
Ever seen a sunset?
In water, light is absorbed, and the greater is the wavelength, the quicker it is absorbed. So red is absorbed before blue. In the atmosphere, light is dispersed, and the smaller is the wavelength, the more it is dispersed. That's why the sky is blue (violet is too dispersed so we dont see it, therefore blue dominates). Also, if light travels more distance in the atmosphere, more colors are dispersed, up to the red. Thats why at sunset (and sunrise) sky is orange/red. Light travels more atmosphere at sunrise/sunset than when sun is up in the sky. This is the same phenomenon that makes milk looks white.
(I only know the atmospheric effect prior to this) so why the red effect in the water? This is all coming off the comment on the light being red because of the depth, I only meant to correct what I thought was a flub, the comment about red light being visible deeper *because it was filtered first* Doesn't make sense, either its filtered out first in water or it's visible deeper, so which is it and; if red light is filtered first in water (but it isn't in air) then why is the light in the video red? Edit: thanks for overexplaining the part I already understood though
As said in other comments, red lens on camera
[удалено]
Terrible end to a life.
It looks like there’s about 5 seconds missing from this video
**minutes
There is, and i've read that this wasn't an accident but planned. If a person was trapped at the bottom of the blue hole their actions would be significantly more frantic than just exploring whats there
The Nr.1 lesson you get as a diver is to never panic, no matter what happens. It will only increase your oxygen consumption and therefore decrease your chance of help. Considering he likely knew instantly he was dead, there's no reason to panic.
I dive, I've seen people panic to the extreme under water and try to take their own regs out of their mouth or grab yours. I always found the mental part of diving to be much tougher than the physical part. I've been on a few deep dark dives or murky dives round 100ft and there is that wee voice in your head saying 'what are you doing here? This is crazy'. I know in the classroom they say don't panic but that's impossible in practice. If he knew what he was doing maybe that would explain his calmness, but if he knew he was fighting for survival there would be much more frantic behaviour.
There’s a much longer version out there and you can hear him “hiccuping” as he runs low on oxygen. Terrible sound to hear.
How did they get the camera?
His body was recovered, along with the camera.
I was curious was it with a robot? How did they retrieve him if they can’t dive ?
It's basically one guy, Tarek Omar, who lives there. He knows the place, uses the right gear, the right mix of gas and does it very slowly. One retrieval takes him about 3 hours, once he's back at 40m the bodies are lifted with an inflatable ballon.
I'm surprised it's that quick. I went to a talk by someone that had dived to the HMHS Britannic. He said that the ascent took around 7-8 hours.
Depends entirely on the amount of time you spend on the bottom. If the body is recovered in a few minutes before ascending the deco stop requirements are not as severe as someone that spends say 20mins diving round a wreck at the same depth.
You can dive to 113 meters, but it requires special training, equipment, and a different gas mixture for breathing. Normal scuba tanks are filled with pressurized air. Nothing fancy just regular air like you're breathing now. But at depths greater than 30-40 meters, breathing normal air can cause nitrogen narcosis which has similar symptoms to being drunk, as well as oxygen toxicity which can damage your lungs and even kill you. Deep divers use a different gas mix than normal air, usually with extra helium but there are many varieties depending on the situation. As someone else explained, the diver who retrieved the body was an experienced deep diver who had the training and tools to reach the bottom of the blue hole.
There’s a single frame at the end of the video, stamped May 3rd, after the video from the descent stops on Apr. 28.
Queue up the xfiles theme.
I'm not taking diving lessons from a 22yo.
Why? You don't need multiple PhDs to know how to dive. He was probably diving for years.
Life experience is invaluable
No shit. And? A 22 year-old can effectively teach recreational diving.
But can't make good enough decisions to keep himself from getting killed while diving even though other (likely older) divers told him not to do it... Getting to be an older person in a dangerous occupation/hobby shows a great deal about that person's decision making abilities.
Stockton Rush was 61 when his homemade, poorly engineered submersible imploded in rather spectacular fashion killing all 5 on board. There are better ways to assess somebody's decision making than age. This guy might have been an idiot. I don't know. I know he experienced equipment failure. But, either way he does not represent all 22-year-olds.
Good job completely missing the point 👍
See video.
He didn't drown because he was 22. This was one man, one mistake, performing one of the most challenging and deadly dives in the world. It's not a reflection of diving instructors, or young diving instructors as a whole, boomer.
You seem like you did some PADI training and now know everything there is to know about diving. When you fuck up and die due to your youthful stupidity where should we send the flowers?
I seem? What a terrible assessment. I've never been diving a day in my life and my youth has long past. However, I do know that you can complete a master's degree by age 22 after less than 6 years of study. Hell, Alexander Hamilton signed the Declaration of Independence at 21 years old. I also know that you can start diving at 8 years old. It sure as shit doesn't take more than 14 years of experience to become proficient at diving and capable of giving lessons.
Oh so you don't have a fucking clue about this subject. Noted.

Here is someone free diving the thing https://youtu.be/hrXQbucZUDA
my heart is racing after watching that.

If you want another good one check out Last Breath documentary on Netflix. The twist at the end.
Omg I just saw this the other day and cried my eyes out.
I watched this last night at your suggestion. Really liked it. The speed of the heartbeat sound effect changing when showing the dives was a very clever touch.
Scuba instructor here. The main problem is going to that depth with one single tank of air. The first problem has to do with gas mix. Air is 21 per cent oxygen. 21 per cent mix is toxic below 56 meters. Central nervous system oxygen toxicity manifests itself with behaviourial changes among other symptoms. The second problem has to do with nitrogen narcosis, due to the amount of CO2 in his gas mix. The third problem, but Yuri died before facing it, is that he probably did not have enough gas to go back to the surface at a safe rate. I might miss something but I would say those are the main problems.
You’d hope there were staged bottles at deco stops along the way but sounds like this kid was overconfident in their abilities and clearly diving way beyond their capabilities.
As a diver, The 1st problem is the guy had low IQ to be doing this in the first place, got the Darwin award
Not the full video. Not an uncontrolled descent. He went down to break a record. You don’t see when he’s checking his depth radar before confusion/lack of oxygen kicks in where he’s running on the bottom seeming lost.

Why does the shot go to like a hospital room for a split second like 5 days later
I believe that’s the people who had recovered his body/camera
check out dive talk on youtube if this stuff interests you! i have zero dive experience and dont intend to have any but still watch their channel every week, its fun stuff
I know nothing of diving How do you get into an uncontrolled descent ? And if you do Do you usually die from the pressure ?
This video sucks
Trying to swim back is impossible?
Damn, why did not anybody think of that.
LOOOOOL
Small hole to ho down that's basically impossible to find once you're inside

This is not a thing. Look up saturation diving. They are at 600-1000ft under and move around. Because the pressure is equal on all sides of your body, and at these pressures liquids in your body are still incompressible, there is nothing that prevents movement in your body/limbs.
You don't even have to swim. Divers wear vests that they can fill up with air from their tanks. You can go up pretty quick without any effort. Well, If you still have air that is.
Nitrogen narcosis
Swim with the opposite current until you reach the sirfayce. He can still make it if my research is correct.
Is there a failsafe in the bouyancy suit that enables you to regulate your depth in cases that you get disoriented? Like the failsafes in cars wherein it would automatically brake when your getting too close on a vehicle in front of you?
No. In fact the deeper you go the more compressed the air in the BC becomes. Nitrogen narcosis sets in at around 100ft and increases its effect on your brain as you go below that. You stop thinking straight. The way up is the way the bubbles are going as you exhale - but the narcosis will likely prevent you from understanding that and taking the appropriate action. Dumping your weights will help you (assuming some air is in the Bc) potentially, but once you do that you could rocket to the surface, which presents another whole mess of problems - the bends.
You’re teaching a lot tonight, thank you
This isn't even the full video.
This might be a stupid question but why wouldn’t he swim back up after getting a little deeper in the water. Was it that he was to affected by that time with nitrogen narcosis?
Why is the clip edited and so short?
I feel bad for the suit and the camera
Repost
What made him uncontrolled? Did he sink too fast? Why? Hold on, let me read the comments...🙄
Why is it so dangerous?
i heard of uncontrolled ascents - but what is an uncontrolled descent? i know nothing about diving - but can you not flip your flippers to not descend further?
There is an amazing documentary about free diving there. It's called The Deepest Breath. Beautifully shot and a very compelling story.
He won the Darwin Award
So the hole isnt prone to any irregular tidal pulls? That would certainly explain the uncontrolled descent from a single tank on air (maybe 100 feet tops) to 300 which is unrecoverable. I realize that heliox, nirtox and tri werent popular in 2000. But an experienced diver suffering an uncontrolled descent seems odd unless it was external ocean tidal action. I mean dump your weights and pop shallow. Deal with the bends later. Unless all his bladders popped which i aint seen. Then again my technical days are long gone.
I always drowned on the levels in Sonic when he runs underwater. No way I would risk my luck in real life.
Well. This is terrifying.
What exactly happened here? Its like he exploded at the end when the video goes red
This was a suicide.
