I’m anxious to see any in-depth articles from diving magazine sources that will assuredly come out. If anyone is aware of any, please post

According to Australian news they’re all out: The Thai boys are free. But how did they end up kilometres underground?

I’m watching a live feed in Perisocpe and the blogger on the scene says people are celebrating that the last person - the coach - has been safely removed. The same feed is saying Thai and Australian news is reporting this but I’ve not confirmed this myself. Could it be?

According to CNN, TEN boys have now been rescued. Phase 3 is in progress God speed

CNN reporting SIXTH and SEVENTH boy pulled out alive

A FIFTH boy has been safely removed by the sresuce team! A sixth is on the way https://www.google.com/amp/s/www.express.co.uk/news/world/985952/thailand-cave-rescue-news-latest-update-thai-operation-resumes-stretcher/amp

Good job Ken! We shall see indeed if they correct. AND I’M SO HAPPILY SURPRISED TO SEE THE RECOVERY UNDERWAY SO EARLY AND SO SUCCESSFULLY IN THIS MANNER!

I’m following the rescue efforts of the boys trained in the Thailand cave. I feel like I’ve read every article about it. As an experienced diver with rescue and AAUS training, diving them out of those conditions should be an absolute last resort. What I don’t understand about the coverage...

Thank you Simon, your second paragraph nailed it for me. Much appreciated! That also leads in to why Nitrox has its depth limitations due to partial pressures of oxygen causing oxygen toxicity.

Hello, I've long understood the concept of decompression sickness. That is, if you ascend too quickly without properly off gassing you build up nitrogen bubbles in the tissues of the body. I accept this without question of course, but I admittedly don't know why oxygen isn't equally bad. Can...

Note: Shot w my GoPro 3+ in 1080p, 60FPS

Sighting of a two spot octopus off the California coast, approximately 100 ' (30m) down @ Farnsworth Bank, 30 miles off the coast of Los Angeles, CA. PS - The loose pressure gauge/computer was due to a snapped lanyard. Be kind.

Thank you all for the thoughtful responses! It appears my answer is what I had ultimately came up with. Again, I'm very grateful for all you guys chiming in with such detail. Great board!

I believe I may have figured out the answer for myself since it wants the answers expressed in psi. Fresh water is .432 psi per foot. At 34' feet (1 ATM), that's 14.7 psi. At 59', its 25.5 psi. Absolute would be 39.7 psi. Perhaps the answers are 25.5 for gauge pressure, and 39.7 for absolute...

Unfortunately I have to treat it like a real question and I can't refer to a book. Its from a lecture and my notes aren't sufficient on this topic. I only wish, as well, I could round off measurements, meters or feet, whichever. But we're indeed calculating SAC (surface air consumption rates)...

That's a good cautionary tale. I'm an experienced diver so I own my own gear but only did so after I probably logged more than 100 dives. It makes sense for me but for newcomers it's really not worth jumping in to it. One of the pitfalls of buying your own gear if you're not going to be an...

I'm taking an advanced course and learning about gauge pressure vs. absolute pressure. A take home test question is as follows: "The gauge pressure at a depth of 59 feet in fresh water is ____ psig and the absolute pressure is ___ psia." Is this another way of asking about ATM vs ATA? I know...
