So many of these comments are idiotic, perhaps attempts at being funny.... HaHa! Cameron can do whatever he pleases and maybe he'll find something interesting, but its an adventure in any case. I think that maybe there's a lot of jealousy in many of these comments, mostly from men who crave adventure but are trapped in boring existences.... Go James Cameron!
We breathe approx 500 ml per breath and an average of 7 L per minute
YES, ALASKA IS A BUTT BRAIN. OF COURSE ONE MIGHT DEFEND HIS/HER RIGHT TO BE AN IGNORAMUS BUT THAT FAILS TO CHANGE THE UNDERLYING FACT WHICH DEALS WITH A THINKING DEFICIT.
Huh!? What are you on?
HE IS COMING TO THE MOST BEAUTIFUL PLACE IN THE WORLD SAIPAN...
AND ITS IN AMERICAN TERRITORY-OCEAN VIEW APARTMENTS 6-$700.OO A MONTH!
check his stomach as soon as he gets back, thats all I ask. No room for lawyers and bankers on that thing, too bad.
Jimmy Hoffa was the THIRD visitor.
Hey, what about the strange round object found in Baltic Sea? Better not to talk about it, uh?
I see no point in going down to a place where nothing lives and total darkness to maybe risk your life for nothing.
How do you know? Have you been there? In 1960, they found life, unlike anything else on the planet and just maybe, the findings will save us from starvation as the population continues to grow exponentially. That is enough reason to go, let alone the fact it is the most unknown portion of the planet we live on.
It is better than wasting money to go to space, at least we know there are animals living in the sea.
I salute you Mr Cameron, can't wait to see what he finds
shows what you know... there are amazing creatures that can live at such extreme pressures but you wouldnt know that since you obviously are not intelligent.
Because "Alaska" has a different opinion than you means Alaska isn't intelligent? People explore for lots of reasons, and sometimes their findings are a benefit and sometimes they're not. Be cautious about accusing someone of being "unintelligent" because they disagree with you.
I'm King of the World!! The Underworld!!
watch out for the Requiax
The original TRIESTE is now on display at the Naval Historical Center, Washington D.C. TRIESTE II (DSV-1) was DEACTIVATED in 1984 and is now on display at the Naval Undersea Museum located at 1 Garnett Way in Keyport, WA 98345
The late James Cameron. Too bad, I kinda liked the guy.
This is gonna be insane! Go for it dude! Best of luck!
America 1st: u r already forgotten you hapless nimwit.
Go for it ! Wish I could be there too.
my uncle's ship went down in marianna's trench during the war, it would be nice to see if they could find any of the remains of nhis ship or any others that were unaccounted for.
Doesnt Osama Bin Laden live there now?
Jesus lives there..... JESUS LIVES THERE!
Bless all yee who enter! Oh bless me.....oh forgive me for thee hath sinned.
wow amazing 😀
Thar be monsters there. Beware the Kraken. Aaaargh...
Or maybe just an empty Asanti water bottle.
Can't wait to see the movie.
They are going to find an entire society of aquatic beings that do not tolerate liberals or gays. Then they will start a war on humans for invading their territories and attempting to inteject gay reasonings and liberal dogma. All because some rich guy is bored. Seriously dude if you have a bunch of money burning a hole in your pocket couldn't you try to help the homeless or put needy kids through school? Or provide free daycare for single moms so they can go out on dates and stuff?
Jeeze, don't you have another argument besides that one!!! What the hell do you know about what he does with his money, how do you know that he doesn't donate to a million charities already? Oh right, you're a nut job (and there seems to be an epidemic of them in the states) that just assumes he knows everything about everyone!
Seriously? Exploration for the sake of exploration has been a trademark of human kind since the beginning. So why spend money exploring Mars or Jupiter? It is his own money – what do you care??
so then, they are going to find a colony of Christians huh !
What good would that do?
Were he to spend all his millions, there would literally be billions of people in financial peril. Or were you thinking of the rest of the world?
His investment will distract millions from their sorrowful plights and provide them with a sense of wonder for an hour and a half.
No. His is the better choice.
there have always been needy and there always be. Spending money on them will not fix the problem.
Exploration is for all of humanity and it trys to provide answers to the basis questions of how, why, what.
Ocean and Space exploration are not a waste of money. They can yield valuable resources of which could be benefitial for mankind. Being economically capable of conducting such exploration is no different than the government providing NASA with the funds to continue its mission, thus generating jobs. Now, this gentleman may be doing just that. Creating direct and indirect jobs in our market. I think that single moms can get their own dates without any help.
I agree, rich people should be forced to use their money to provide for others. Don't forget to vote democratic all the way.
I believe what he has done in incredible and will spur interest in pushing scientific research. Its far better for this to be privately funded out of interest instead of government funded out of waste and corporate funded out of bias.
Eshpigmenou's pool is deeper than that.

Do we have technology yet that can take some to the depths of 36,100ft. That is crazy. Would love to see that. I can't imagine the pressure at those depths.
(At more than 10,900 meters (35,800 feet), the Mariana Trench is deeper than Mount Everest is tall, and has had only two previous human visitors. In 1960, U.S. Navy Lt. Don Walsh and the late Swiss explorer Jacques Piccard descended into the deep in the bathyscaphe Trieste.)
this was in the article
Basically, the calculation is one atmosphere per 33 feet. So, at that depth, the pressure would be 1093.93... atomospheres. That to me is so brutal, it is hard to comprehend.
Here are the numbers: Sea level atmospheric pressure = 14.7psi. Pressure increases at a rate of 0.445 psi per foot in sea water. Outside water pressure @ 35800 ft depth = 15,945.7psi, @ 36100 ft. it = 16079.2psi.
Using metric is easier. One atmosphere (ATA) is 10 metres. So 11,000 metres would be 1,100 atmospheres. On average you breathe 7 litres of air per breathe. If you were at 10 metres or 2 ATA each breathe would be 2 * 7 or 14 litres. In the Mariana Trench you'd need to breathe 7700 litres of air in each breathe to counter act the pressure. You'd be breathing the equivalent of 22880% oxygen if you used air. You'd have to have a gas mixture with something like 0.1% oxygen, 0.6% nitrogen and 99.3% helium in order to survive. Bottom line, not a human friendly place to be.
Can't we just go to the moon again?
7 liters per breath? That can't be right. That's almost 2 gallons per breath. I do have a large chest, but not that large 🙂
you definitely do not breathe on average 7 litres of air with every breath 7 litres of of is about the total lung volume for a fully grown man each breath is a tidal volume and is usually around 500ml or 7ml/kg of body weight but for that to be 7 litres you would need to weight quite a bit more than a human could ever weight.
As well how is 1 Atmosphere the equivalent of 10 meters?
no, at least 7L is right (although I think the number is higher) – gas is smaller under pressure.
For those who have never been scuba diving, approx.10 meters of water = 1 atmosphere of pressure . Essentially, the deeper you go, the exponentially more volume of gas you need in your lungs in order to maintain your breathing as your lungs are compressed by a reduction in gas pressure.
Your calculation is accurate if he were OUTSIDE of the submarine. But since he's INSIDE, he will probably breathe a normal mixture of air and undoubtedly at nearly normal pressure. What's truly insane is the fact that his submersible does not implode from having 1100 atmospheres of pressure squeezing the bloody life out of it. How life can exist at those depths is EXACTLY why he's going down there. For if life can be found in an environment with 1000 atmospheres of pressure, it opens up the possibility of life in our solar system (Jupiter comes to mind) and beyond...
