It"s the deepest part of the world"s ocean and the lowest elevation of the surface of the Earth. Yeah, it"s that deep.

@omg-a-lion ..Thank you for reminding me about a movie that totally wasted an hour and a half of my life... I want that time back.

fredg3 & BlastechDL44:
There IS confusion in the document. The Hadal zone extends from about 6096 meters(20k ft.) to the bottom, whatever that may be. The pressure at 36k feet, the bottom of Mariana Trench, is about 16kPSI. However at 20k ft. the pressure is approximately 9k PSI.
BlastechDL44, you forgot to multiply by the 14.7 PSI.
E.g., 20k/33 = 606.0606; 606.0606 *14.7 =~ 8909.0909 =>~ 8909 PSI at 20k ft.
...or roughly 9k PSI.
That`s a guesstimation method.
The more proper method, using formula that gives the P pressure on an object submerged in a fluid( P = Ï * g * h ) and adding atmospheric pressure on the surface yields ~ 8896 PSI at 20k ft.
* Ï (rho) is the density of the fluid, (density of sea water = ~1025 kg/m3 )
* g is the acceleration of gravity (9.8 m/s2)
* h is the height of the fluid above the object

The author of this pic got confused, most likely, because the wiki document referen

No, BlastechDL44, YOU`RE WRONG. The illustration does NOT claim that 20,000 ft = 1,100+ atmospheres. The relationship is between pounds per square inch at the surface of the earth and at the depth of 20,000 feet. That is, it`s between 16,000 psi and 14.7 psi. (14.7 psi being the pressure from the atmosphere at sea level.)

So you can wipe that smug look off your face now.

I`m surprised there are five pages of comments and no one has caught the fact that this striking image contains bogus numbers.

The pressure of seawater increases at a rate of about 1 atmosphere per 32 feet (33 feet in fresh water), give or take.

The claim made in this image is that 20,000 ft = 1,100+ atmospheres. That is incorrect. 625 would be more accurate.

The pressure at the bottom of the challenger deep is over a thousand atmospheres, according to the wikipedia, and basic arithmetic.

So, its a nice illustration, but factually incorrect.

Holy s**t.
It`s stuff like this that really makes you think.

Another thing - http://en.wikipedia.org/wiki/Deep-sea_gi...

deep sea gigantism..I remember when the waves would come in and if you dig fast enough you can grab one of those little guys and watch him scurry around, these are over a foot long..what the hell else could be down there and grow even bigger!?

Male 1,093
thats crazy. Machines can barely make it that far, yet life still exists there. makes you wonder
Male 2,220
The chimeara Harriotta haeckeli has been retrieved from 2600m by russian trawlers, and bluntnose sixgills are thought to go down to about the 2000m mark (Source Elasmodiver). Some scientists don`t think you`ll find sharks below the 3K mark - but so little is known about these depths...
Female 914
how far down can sharks go down?
Male 894
thats intense

regalia13: "Trieste departed San Diego on October 5, 1959 for Guam aboard the freighter Santa Maria to participate in Project Nekton, a series of very deep dives in the Mariana Trench. On January 23, 1960, Trieste[1] reached the ocean floor in the Challenger Deep (the deepest southern part of the Mariana Trench), carrying Jacques Piccard (son of Auguste) and Lieutenant Don Walsh, USN. This was the first time a vessel, manned or unmanned, had reached the deepest point in the Earth`s oceans. The onboard systems indicated a depth of 11,521 metres (37,799 ft), although this was later revised to 10,916 metres (35,814 ft) and more accurate measurements made in 1995 have found the Challenger Deep to be slightly shallower, at 10,911 metres (35,797 ft)." ~Wikipedia, Bathyscaphe_Trieste.
And now they`re finding ways to make robotic subs. Who can keep up with this techonology?! If we keep this up, we`ll soon invent somekind of coneshaped vehicles and fly to the moon!
Female 212
@skirjames

They are finding ways to build things like robotic subs they can control in the extreme depths. We actually do have pictures of the Abyssal Zone, I`m not positive on lower than that.
The biggest fear is send a human down because a sub would get crushed like a tin can, but from some research I did a year or two ago they have been working on subs or other robotic devices to send down to those depths. One of the biggest problems though is the ocean`s current. It`s hard to have things land where you want them to as they drift.

Male 86
I feel like I should be Google image searching the Abyssal Zone, but I don`t think my pants need any crapping today...
Male 1,485
wow, thats freaking HUGE!!!!
Male 109
This is some SERIOUSLY interesting stuff and one of my favorite posts in a long time. I really don`t know much about such deep marine life but is there anyway we can encase cameras with lights to drop down there and take pictures? Or is the pressure nothing our technology can handle? I would seriously love to know what`s down there..I suppose for now we can only imagine.
Male 154
still not as deep as your mom....

Male 703
and

AND

perhaps you should stop over-analysing a drawing, and take away from this what was intended - i.e. the Mariana trench is flipping deep.

Male 2,220
and (frothing at the mouth now)

AND

The blue whale is drawn too small - I make it about 60ft long. It should be almost twice that length.

Male 2,220
Hold on - what`s this cr*p about 350ft being the maximum dive depth of a blue whale? Says who? I thought that was about the level of an *average* blue whale dive. Besides blue whales are pansies. Sperm whales are thought to be able to reach several Kilometres down and Cuviers have been confirmed at almost 2km...

"I made it to the Hadal Zone one time on a single breath of air. No big deal. "

Dude it takes more than a single puff to get that bombed.

Its a shame they didn`t have the freedive marker on there though. 214 meters, according to my rather basic PADI knowledge that`s 21 atm. Seriously scary stuff.

Female 718
I bet there is something amazing at the bottom...

Isn`t it sad, more people have been into space than have been to those depths. On pretty much every expedition they find at least 1 new species.

DarkFerret "I wish i could go to the bottom of that... just to say i did it."

I bet if you did, it would make your ears pop.

Male 122
@ last_ninja because the world is 70% Ocean. Only recently have we had the technology even to explore such depths. Look how long it took to discover the America`s. Exploring the Oceans will take a long long time.
Female 465
Wow
Female 498
Male 610
why is only 10 percent explored? that`s strange.

I have a reacurring nightmare about that trench. Dropping, incased in a small metal pod, cut off, no rescue.

@HKelch

Trench, not a hole. But yeah, you`re right.

I like how everyone is commenting on how mindblowing the thought of all of this is and the creatures that would be at the bottom.

But my mind immediately goes to "That would be a great place to dispose of a body."
Granted, I`d have to find a way to get myself and the body there. And I would never need such a place. =] But a great place nonetheless.

Woah! I Came across this on Stumble last night! NOw it`s on IAB, minddrat!

BTW i tried elongating the word `minddrat` only to relize that it wont censore it so...yeah. Just putting that out their.

Female 126
Look at this... NONE of the animals living deep under is cute... NONE :( I was hopping to see some bunny like fishes... even clown-fish ha

holy poo. that`s scary and f*cking awesome at the same time
Male 30
And that`s why nature is so awesome.

wow, I knew it was deep just not that deep.....now I am really scared of what could be down there

"I`m still a little afraid to go in water if my toes can`t feel the bottom."

I`m still afraid to go in water if I can`t see the bottom.

wow. i wonder what they will eventually find living down there.
Female 864
It means light can not penetrate from the surface .
Female 133
boadicea: It basically means that sunlight has totally dispersed by the depth, and therefor it would be dark. If you took a torch down there it would still work :)

But perosnally I wouldn`t wanna see down there lol

Female 1,545
Boadicea, they mean light from the sun is no longer visible at that point...from that point on, it`s completely dark.
Female 751
holy crap!!!
Male 848
Not quite.
At that point, sunlight cannot penetrate.
It is blocked by the vast amounts of water above.
If an outside source of light is brought down then that works.
Male 42,934
vv Sunlight it means, pictures and film shows a LOT of stuff sort-of suspended in the water, but you can shine lights a little ways. Sunlight, the source of most other life, doesn`t shine here tho.

Trez Kool!

Female 1,677
My brain cannot comprehend. When it says light cannot penetrate at that point, what does that mean? Like if you somehow managed to get a lamp or something in there (work with me), flashlight whatever, it wouldn`t project light? Anybody?
Male 914
very cool
Male 75
The further I scrolled down, the deeper became my sense of foreboding.
Female 105
I once heard if you dropped a lead ball at the surface, it would take an hour to hit the bottom it is that deep.
Male 496
I swear, I stumble upon new stuff and then the next day its on this site. Get original for drats sake!

This is pretty cool, remember watching a documentary on this ^^
Though, in that documentary, there was another, smaller trench with what sounds like 10x the pressure from all the salt residue.

Crazy to think how little we know about our own world.
Male 15,510
Its incredible we know more about the surface of the Moon than the Ocean
Male 758
It`s crazy being on a submarine and diving...the boat (if you`re in a quiet spot, like berthing or Control) you can hear it creak and pop. Some doors didn`t like to work on the sub I served on, when we got to test depth.
Scary stuff, knowing you`ve got xxxxfeet of water between you and your next breath if something goes wrong...

The blue whale can dive to a depth of 1,640 feet

oh I watch a documentary on that and was just creepy seeing how deep it is. I am not really afraid of water but afraid I guess of not knowing what is down there.

Technically, doesn`t IAB and cracked share something? Thus it is not really stealing. I don`t remember how it works...

Yep, pretty deep.

I love things like this, just huge-scale mind boggling.
yay for science :)

This is the kinda stuff there should be more of on IAB instead of pictures stolen off Cracked.
