Record-breaker diver finds skeleton
From correspondents in Johannesburg
October 30, 2004

AN Australian deep-water diver attempting a world-record dive in South Africa found the skeletal remains of a fellow diver who disappeared down the same sinkhole 10 years ago, South African radio said today.

David Shaw found the remains of Deon Dreyer, who died at Boesmansgat in the arid Northern Cape province in 1994, at a depth of 271 metres, SABC radio said.

The Australian said he wanted to go deeper, but decided to stop after making the grisly discovery.

Mr Shaw did however break the previous record of 242 metres for diving with special equipment, rather than normal scuba gear.

He took nine-and-half hours to resurface, spending most of the time decompressing.

Z-Hills. It happened when you said, same jump numbers! Cant remember his name off the top of my head but none of us were suprised. He was a little cocky for such low experience. I wasnt at the landing area at the time I was at home and I just heard about it the next day.

Wow - that deep, the pressure is about 400 PSI! I wouldn't doubt it would take several hours to depressurize. I wonder what you would look like if you had a bouyant device that brought you to the surface quickly. Probably a mess of blood and bones.

You wouldnt explode if you came up from that depth that fast. Unless of course you held your breath. But you sure would have a Nasty case of DCS. Then again the article didnt say anything about what his breathing mix was. Obviously not Air.

I seriously doubt that. Technical/Deep diving is extremely complicated and requres many hours of planning and vast amounts of support. If someone were to try and dive to that depth while breathing air they would be dead way before 271 meters. They wouldnt last much past 80 meters. At that point they would be suffering from both extreme Nitrogen Narcosis and Oxygen Toxcicity. Anybody who dives to 271M and lives to tell the tale is a serious professional.

Hrmph, my NAUI cert's only to 130 feet, but it gets a little dark down that far and you've only got a few nondecomp minutes anyway. Does PADI still go to 100 feet, or have they hit some kind of agreement now? Maybe the guy wanted to go deep just to get narked!

That's why I said some sort of floatation device, to make him come to the surface quickly, before allowing his body to depressurize at all. That much pressure, if you don't give your body time to depressurize, would probably tear you apart.

Any air in your body has to be at an equal pressure as well, and if it's not, the body cavity that the air is in will try to collapse until equilibrium is reached.

Fish brought up from their habitats far down in the water will die very quickly and it's not unknown for them to actually rupture if they're brought up fast enough from deep enough water.

Very true CM. I've brought up grouper from 60 feet that had their swim bladders pop out. It looks uncomfortable for them.

Not BS. Middle grounds in the gulf and the bottom of the ledge was 139 on my guage. I moved up to 120 right quick. I had been told the bottom was 120 and I went all the way down without checking. I kid you not. Short exposure at high partial pressures is or can be OK.

From DANs website.



For open-circuit scuba diving, consider the "green light" region any oxygen partial pressure of 1.4 ata or less (this is about 82 feet / 25 meters on a 40-percent oxygen mix.) As long as this level is never exceeded, other limitations of open-circuit scuba diving will limit the exposure time to lengths where CNS oxygen toxicity is unlikely to be encountered, even for exposures approaching four hours.

Proceeding With Caution

Between 1.4 ata and 1.6 ata (this is 99 feet / 30 meters on a 40-percent mix) is the "yellow light" region. The possibility of oxygen toxicity at 1.6 ata is low, but the margin of error is very slim compared to 1.4 ata. Individual variation, the likelihood of an unplanned depth excursion causing an increase in oxygen partial pressure, and the possibility of having to perform heavy exercise in an emergency put the possibility of oxygen toxicity at levels where caution should be exercised. Thus, levels of 1.5 to 1.6 ata should be reserved for conditions where the diver is completely at rest, such as during decompression. Again, as noted previously, the dive team must still be prepared for the possibility of an oxygen convulsion at these levels.

Stop!

Above 1.6 ata is the "red light" area. Just don't do it. Yes, there is evidence that short exposures at higher levels of pO2 (oxygen partial pressure) are possible but so are convulsions. At these levels, oxygen exposure depth/time limits must be adhered to. Even mild exercise may put divers breathing high-density nitrox mixes at increased risk; and even open-circuit scuba divers can achieve durations likely to get them into trouble at these levels. Diving using these high partial pressures of oxygen should be left to the trained professionals who can weigh the risks and benefits and who have the necessary training and support structure in place, if an oxygen convulsion occurs.

Finally...

I went to 162' in Hawaii in 1997. I was younger and stupider and just wanted to see how deep I could go. I realized I was narced and headed up to my wife/buddy at 120'. I was very lucky and I won't be doing that again.

He makes those "extreme sports" guys on MTV look like a bunch o pussies.

Bonus: He actually looks like Sammy Hagar.




Thanks Brass.

DAN did a study a while back as well that said no one has ever taken a CNS hit at 1.6 ata within exposure limits. The only time my computer has ever put me close to overloading on O2 was on a liveaboard trip in the Keys diving 32% after 4 days of 80-90' foot dives.
I only ever put myself into deco once as well and that was before I was certified.

I've been to over 150' on air. When you're at a 4000' dropoff, and slightly narked, it's unfortunately too easy to loose track

British technical diver Mark Ellyatt is reported to have safely completed a dive to 311m (1026.9) feet in Thailand.

The previous depth record was set by British diver John Bennett, who was the first person to dive below 1,000 feet when he set a 308m record off the Phillipines.

Ellyat is reported to have taken 12 minutes to descend, with six hours and forty minutes of decompression. He carried six cylinders of bottom gas and was supplied with a further 24 cylinders by support divers during his decompression stops.

Never having been deeper than the bottom of a 14 foot deep pool, I'd have to wonder what it felt like to be under over 1000 feet of water. What's it feel like to be operating under 457.4 pounds of pressure per square inch? When doing deep dives, do you feel anything different from a shallow dive?


CJ



I'll tell you what I feel. The physical thing is really nothing the deeper you go but mentally its a big difference.
Take a look outside and see how far 100' is. Not much huh? You could walk it in a few seconds right? Go 100' under water and its a whole 'nother ballgame. Now you CANT walk it in a few seconds. Not if you WANT to, not if you HAVE to. Feels kinda weird.
Gotta trust your gear because I dont dive with a buddy.
Link Posted: 10/31/2004 6:14:24 PM EST
As long as you equalize early/often it doesnt feel any different. As long as you know what you are doing and dont dive beyond your training/ability Its all good.
