Line added in D, C, and M may have put us over the 50,000 foot mark in Wakulla. I will add it up later. Dr Johansen and Dr. Chimiak of Navy conducted Doppler testing on the five divers who did the 120 to 150 minute bottom times. All of us did the same deco other than at the oxygen level - I abbreviated mine. All but Rose showed bubbles in the 3-4 class, with the peak occuring predictably 30 minute after the dive, and slowly starting to diminish . Rose came up to a class 2. The one difference is that I peaked almost immediately, and 30 minutes later was FREE of bubbles. Dr. Johansen, who has done this since 1970, said it was the first time he had EVER seen this happen. The normal pattern is to peak an hour later, and then come down very slowly over a period of hours or days. I only have one thing to say about that: V02 MAX. I have the highest score by a very big margin of anyone tested so far . Dr. J disagreed, but offered no other explanation. We will keep testing and let you all know. By the way, none of these guys got "bent". Also, Bill Mee and I are going to modify the tables to try to reduce the surface bubbling. One, we are going to recommend using the lowest ox gas to break to , like Rose did, and two, we are going to recommend a ten minute 20 foot 50/50 stop, and a ten minute 10 foot 50/50 stop. DO NOT GO BACK TO OXYGEN IN THE WATER. You absolutely MUST breath the break gas for at least ten to twenty minutes BEFORE exiting the trough for both DCS reasons ( Bill Mee blew this one and got nailed temporarily in the legs from the oxygen - remember I told eveyone about that, and nobody believes it until they get wacked by it ) , and for TOX reasons. I do not want anyone breathing oxygen in the water after the trough - use the 50 / 50 - you can not fix dead, and if you tox at that time, you will likely die or be so severely injured that you are not fixable, and will never be able to dive again - don't be stupid. It is only for removal of excess bubbles released by the pressure drop. Sit on the surface for another ten before getting out of the water, and breath oxygen there if you please, but do not carry your tanks out at that point. Come back an hour later or get somebody else to do it. I personally do not breath oxygen on the surface, as I have a very good set of filters, but others think it is a good idea - do it if you please, but do it in the privacy of your own van. I do not want people thinking we are all dying or something. I could not believe the showers of bubbles released on the doppler by squeezing the muscles - this could potentially overcome your lungs. I could not hear the type 3's in my heart standing still that Johansen could hear, but I sure could hear them when I did deep knee bends. Interestingly , no amount of flexing or muscular stress could produce even a slight bubble sound on me 30 minutes later. See the "Physiology and Medicine of Diving" for Johansen's work with Doppler and his experiments dating back to 1970. Before you get to stressed out about this, also keep in mind what Chimiak said to me - " the bubbles we are detecting in you are no different than your 'mask ring' - they are evidence that you have been diving". You will see this in the chapters on Doppler , and you will see that this is what happens on any provocative dive. This is why NOT having PFO, fat slobbery, poor fitness, tobacco habit, poor circulation, injuries or other self-indulgent evidence of personal preference or preconditions is a must in extreme diving. I can now see how extremely risky this sport is for those who do not take it seriously. Great dive by Jess Armentourt , Dr. John Rose , and Bill Mee - you guys have elevated yourselves to the top of the sport. You have it all - extremely smart, gifted, good divers, good fitness, and one of the most impressive displays of teamwork JJ and I have ever witnessed. I am extremely proud of you three guys. You are what Doing IT Right is all about - the proof of the pudding. You can now say you are the best, have earned the right to say it, and have proven it to me in every way. Also, Rat tells me that his two buddies, Cole and Werner, have become rock solid players - another great team. The Head's and Straatsmas are long-time seasoned pros, and the Landons et al are rapidly proving to be top notch players. We have a seriously talented group here. By next season there will be no limit to what we can do in the WKPP. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
