Thank you to Steve Minehan for letting us use some of his saturation diving footage!

I have a story from my teacher and diving instructor. He was once doing about a 40 meter dive down with either a student or a friend. His friend suddenly took out his regulator started blowing air into the water. He took that person up and when asked about it, his friend said that he was "giving air to the fishes".

Nitrogen narcosis can be really amusing

This video managed to take a subject that I have had no particular interest in and presented it in such a way that I'm about to binge everything I can to learn more about it! I absolutely cannot wait for the part 2. Thanks, real science! You're clearly doing what you do best

[CommercialDivingFAQ]

Well explained. I'm a Saturation Diver and I haven't found another channel that explains the Commercial Diving world in such easy to understand terms. I'll be linking this in my playlists. Looking forward to part 2.

There's this annoying thing I have with most youtube science videos: They rarely go beyond a certain level of detail and because of that almost never tell me anything I didn't already know. Real Science has taught me something entirely new with every video thus far, so: Thanks!

I am a former U.S. Navy Deep Sea Salvage Diver from the 1970's era and I give this video two thumbs up. Well done!

Crazy coincidence, I treated a retired sat diver (welder) this week and was telling my colleagues about sat diving and playing them videos of men in a tiny chamber talking like Mickey Mouse 😂

[neighborhoodcaptain]

I’ve never thought though I’d say this, but with all the stuff going on on land right now, I think I might move to the sea.

I believe the deepest commercial dive recorded was some 2300 something feet and they had a gas mixture of helium and 1% oxygen because the pressure was so great on their lungs. This stuff is really fascinating.

I'm proud to say, I was a Commercial Diver Medic for 10 years, did salvage, construction, nuclear work, and as exciting as it is, it does take a toll on your body.

As a recreational diver myself who's allowed to (only) go to 30m i can't even imagine how much more challenging saturation diving is. Very good and informative video, looking forward to the second one!

[flytrapYTP]

Idk why but even with all of the bad stuff this sounds so intriguing to me.

One athmosphere on surface, two on 10 meters, three on twenty.

[Berkcam]

When you step out of a sat chamber on reaching surface the first few words out of your mouth are incredibly deep. Your vocal cords have been fighting against the thinness of helium for days and suddely breathing normal air comes as a shock.

[classicjag]

Such a dangerous job on so many levels. I read a story about an accident in one of the pressurized bells and it is unbelievably gruesome. Lots of respect to sat divers and the people that keep them safe.

[Rei-zeeu]

Liquid breathing huh? At this point scientists are just taking stuff from sc-fi and making it real. Also sounds like thing straight from Evangelion.

[asammahina]

This was genuinely one of the most interesting and most well made, and informative videos I've seen in a very long time, definitely earned my like and subscription.

[Deadlyish]

Wow. Mad respect to the guys doing this job. It must be a harsh mix of difficult and dangerous, pushing the human body to do things it never evolved to be capable of.

[thefreediverjohn]

This channel is awesome! Most other channels in this genre will make videos that barely scratch the surface of a topic, and they'll just draw out their videos with a bunch of useless crap. Real science, you're different! As a diver myself who has even made videos on this topic specifically, I learned something from this upload! Thank you, and please keep the videos coming!

Very informative, just a couple of corrections, the limit for recreational diving is 40m not 33m and the absolute pressure at 33m would be 4.3 ATMs ( remember to add the atmospheric pressure) . The air is composed by 78% Nitrogen 20.9% oxygen and 1.1% of other gases which then its rounded as 79% N and 21% Oxygen, the other gases are negligible to diving. In respect of the gas mixtures you got Heliox ( Helium and Oxygen) and there is also Trimix ( add Nitrogen)

[noeljonsson]

Hey so it says that every 10 meters adds another 1 atmosphere of pressure (which is close enough) but then you have 20m = 2 atm and 30m = 3 atm but if you follow this it means that 10m = 1 atm and that 0m = 0 atm, that would mean that it would be a vacuum at surface level which there isn’t. you can’t forget that there is already pressure at the surface which means that 0m = 1 atm and that 10m = 2 atm and that 20m = 3 atm. Just though I should point that out.
