Reminds me of the fantastic movie The Abyss (1)...vaguely recall a similar scene where there's N tanks of oxygen for N+1 people, so they submerge 1 of the crew to lower her (i think) metabolic rate. Curious why they don't have emergency unmanned drones with the crew or why they don't have emergency tanks at their work site (which he was able to get back to) (1) - Not sure how well it has aged ( https://en.wikipedia.o…

She chooses to drown with the idea that she can be revived quickly enough to survive. They aren't trying to share oxygen or anything.

This article is quite fascinating, but the title is a bit misleading. The diver was about 100m deep. He was on the sea floor but arguably not "on the bottom of the ocean" (though maybe, by some interpretation)

what is the sea floor if not the bottom of the ocean?

>what is the sea floor if not the bottom of the ocean?

One could argue that the bottom of the ocean is the lowest point on the ocean floor.

Commercial divers do have extra breathing gas in the bell, which is positioned at their work site. The problem in this case was the bell was dragged out of position.

Wow that was an interesting read! This quote got me. All because of compression & decompression. > “It is quicker to get back from the Moon than it is from the depths of the sea in some ways.”

The polar station in Antartica is also quite inaccessible during winter. Winter-overs are proud of the fact that they are more remote than the ISS. There you can get in a Soyuz and be back in 90 minutes. In Antartica it might be a month before they can airdrop supplies, maybe four month until they can airlift you out.

>If you lower the brain temperature down to 30C (86F), it can increase the survival time from 10 to 20 minutes. If you cool the brain to 20C (68F), you can get an hour. Wow, I actually didn't know this until now. Is this method used anywhere in medical procedures to resuscitate or prolong life?

The popularized way to say that is ”Nobody is dead until warm and dead”

See for example https://www.ncbi.nlm.nih.gov/pubmed/24882104, which states ”the longest time from cardiac arrest to return of spontaneous circulation was 6 h and 52 min”

Question for the medical readers: a person dies when brain dies from lack of blood flow, right? So all those injuries, say a car crash where heart will stop soon. 1) Disconnect the head from body 2) plug it into a machine that supplies blood, etc 3) the body is repaired 4) reattach head to body. Overlooking the obvious trauma, is this possible?

While extreme/traumatic, I think it could be more reliable as other factors below neck are taken out if equation to dramatically increase chance to survive. Other methods rely on hoping the body isn't too broken to recover. Ie restarting heart, etc then literally giving up as the brain dies from lack of blood flow.

A lite version of above is cutting the veins in neck and attaching a dialysis. Would this lite method work?

Source: Hearsay reports of moving lips from beheaded woman was literally inspiration for this idea, not futurama heads.

It's a great series about exploring Antartica, where the title came from the fact that it takes longer to reach Antartica than to reach space.

Well, in a way yes, but then so is wading next to the seashore. Think of the converse “at the top of the mountain.” At least I’m thinking some peak and not just on a slope up the mountain.

To be more of a smartass than a pedant, but... the bottom of the sea?
