ABC Primetime Deep, Deep Diver Story

[marshallkarp]

Heroic? How so? As I was watching it unfold, I was thinking they were making lots of really bad choices.

When I first read the original article in Outside, I had the uneasy feeling that this was very dangerous and should only be attempt by a professional recovery dive team. This was not your average search and recovery mission, only stretched way out.

Still my condolences to the families. I am sure the show brought back all these memories and new curiousity by who knows how many viewers.

I felt the same way but from the report it said that this would be the deepest body rovery ever. There should have been 2 divers at the body instead of being separated. I tried to watch the video when they showed how Dave Shaw fumbling with all the cords but had to look away, it was too much for me

Lemurs2, I hear what you're saying about having two divers, but first off, how many people in the world are capable of that dive. Even his partner hadn't been to the bottom of that system before. They said at the beginning of the show that there are fewer people to have SCUBA dived past 250m (~820 ft) than have been on the moon.

Thank-you. I really appreciated that article. Now
I'm curious about this statement:

When a cave diver breathes too heavily at
extreme depths[...]carbon dioxide can build
up in the lungs, resulting in a blackout.

There were a number of misstatements in that video. I had watched it before, but was watching it again last night and just cringing asthey were talking about the divers' wetsuits, when I am looking at the DUI patch on the guys drysuit.

I've been on a rebreather, but certainly not enought to know about CO2 production and retention at depth. I'll let one of the CCR guys tackle that. It was curious that it was done on an inspiration though.

I'm about to make a an internet version of that video. So I can watch it again.

It was curious that it was done on an inspiration though.

Dave Shaw's buddy (I can't remember his name) was on the Inspiration, I'm pretty certain Dave was using a heavily modded MK15.

I watched the show, and it was very sad. I don't think I'll ever do more than no decompression dives....

Obvious CO2 can build up
if you don't breath enough. But can CO2 build up
from breathing too *heavily*? Is that be a re-
breather thing, like it can't scrub faster than
you can make it?

--Mike

CO2 build-up is from short, quick, shallow breathing. I think they misued the term "heavy breathing." Heavy breathing will actually deplete too much CO2 (ie. hyperventilation).

Thanks for the clarification. Thinking back, I remember seeing a different type of canister on his back. I thought it was a Meg for a second, but didn't see the tell-tale "bumper" prevalent on all the newish Megs.

I also watched last night... and I don't think that ANY search and rescue team would ever even attempt to do something at that depth. And as many mistakes, that they may have made or we thought they may have made, this is NOT something that is done on a daily, let alone regular bases. So we cannot speculate that they were wrong... they pushed the envelope and came out loosing.

My thoughts and prayers go out to those people. I know I will never be one... I am a big chicken!

His partner saw that his light wasn't moving and descended some to see if he could reach him. However, he then ended up sick during his decompression. How many of us would've played it safer and not descended?
