The Ocean is Way Deeper Than You Think


The ocean is really, really
deep, deeper, in fact, than most of us realize. If you were to shave
off all of the land from the tops of every continent
and island in the world and fill up the ocean’s
deepest points with that land, then the entire earth
would be covered in an ocean 2 miles deep. Three fourths of our
planet is already covered in water though,
and it goes a lot deeper than just two miles. Let’s start with
a sense of scale. This dot right here is the
size of an average human. This slightly larger dot
is the size of an elephant. And this is the size of the
largest ship ever built, the Knock Nevis. With that in mind, let’s
start going under water and see what we find out. The first milestone
is at 40 meters below the surface, which is
the maximum depth allowed for recreational scuba diving. A little further
down at 93 meters is where the wreck of the
Lusitania was discovered, which is interesting
because the Lusitania itself is 240 meters
long, which means that it sank in water
shallower than it is long. So if the ship was standing
on its stern or bow, it would be sticking
out of the water. Just slightly deeper
than that at 100 meters is where diving can become
seriously fatal if you’re not careful because of
decompression sickness. But that didn’t stop a man named
Herbert Nitsch to accomplish the free diving world record
at a depth of 214 meters. This guy swam down to this level
with just one single breath. But a little further
down at 332 meters, we have the scuba
diving world record which was accomplished by
another man named Ahmed Gabr. If he had swam down
another 111 meters then he would have reached the height
of the Empire State Building if it was submerged under water. And a little further
than that at 500 meters below the surface, we
arrive at the maximum dive depth of Blue Whales, the
largest creatures on the planet and also the limit of the
US Seawolf Class Nuclear Submarine. At 535 meters we can
witness the maximum dive depth of Emperor Penguins. And this is one we must bring
up the intensity of water pressure. At this level below the
surface, the water pressure exerted on a person
or the penguins would be roughly
equivalent to a polar bear standing on a quarter. So further down the
depths at 830 meters would be the height of the Burj
Khalifa in Dubai, the tallest building in the world. Once we hit 1,000 meters
below the surface, we begin to enter
the scary zone. Light from the surface can no
longer reach beyond this point, so the rest of
the ocean below is shrouded in permanent darkness. On top of that,
the water pressure you would experience at this
point would be about the same as if you were standing on the
surface of the planet Venus, meaning that you would
die very quickly. You would also meet the
Giant Squid at this sea level if the water pressure
didn’t already kill you. At 1,280 meters we reach
the maximum depth dived to by the Leatherback Sea Turtle. And further down
at 1,828 meters we would reach the deepest
part of the Grand Canyon were it to be
underwater with us. Down at 2,000 meters, we start
to encounter some of the more terrifying sea creatures
like the ominously named Black Dragonsih, a carnivorous
beast with a stomach that doesn’t allow light to
be emitted through it. Meaning that since we are
in total darkness underwater at this point, the only way
you would ever see this thing is with a flashlight. A little further
down at 2,250 meters we would reach the
maximum depth dived to by both Sperm Whales and the
very frightening Colossal Squid. Sperm Whales often have
sucker marks and scars left on their bodies from
battles with the Colossal Squid that likely take place at
these incredible depths. The squids themselves can
grow to be 14 meters long and weigh up to 750
kilograms with eyes the size of a dinner plate
and razor-sharp sickles in the middle of
their tentacles. So yeah, good luck
with that down there. Way further down
at 3,800 meters we can find the wreck
of the RMS Titanic. And a bit past that
at 4,000 meters, we start to enter the
Abyssal Zone of the ocean. Water pressure is at an
astonishing 11,000 pounds per square inch down here. And there are numerous
strange, almost alien like creatures that
inhabit these depths, such as the Fing Tooth,
Angler Fish, and Viper Fish. Down at 4,267 meters
is the average depth of the ocean where
you would normally expect to hit the floor. But there are parts of the ocean
that go significantly deeper than even this. At 4,791 meters rests the
wreckage of the battleship Bismarck, sunk
during World War II. And way down at 6,000
meters is the beginning of the Hadal Zone, named after
the underworld Hades, itself. The water pressure
down at these depths can become 1,100 times
what you would experience way back on top at
the surface, which is roughly equal to an elephant
balancing on a postage stamp, or a single person carrying
the weight of 50 Boeing 747 jumbo jets. Down at these depths, you
would be crushed immediately without any outside protection. But life still exists down
here in various strange forms. At 6,500 meters we
reach the maximum depth that the DSV Alvin can
dive to, a popular research submarine that helped
to discover the Titanic. Way further down at 8,848 meters
below the surface and we have arrived at the height of Mt. Everest, were it to be upside
down and placed underwater. And then way further past
even that at 10,898 meters, we arrive at the depth reached
by James Cameron in 2012 during the Deep Sea
Challenger Mission. The deepest point of the
ocean yet reached by humans was back in 1960
though, when two men named Don Walsh and
Jacques Piccard reached a depth of 10,916 meters using
their [? Trieste ?] submarine. It took them five hours to
descend through the ocean to this depth. And they only stayed
for 20 minutes before a window cracked and
they began to resurface. Just a bit further
down from there at 10,972 meters and we’ve
reached the average flight altitude of a
commercial airliner. So if you’ve ever looked out
of a window while on a flight and looked down to
the ground, that’s a very good sense
of how incredibly deep down into the abyss
that we are currently at. Finally, when we
hit 10,994 meters we have hit the bottom
of the known ocean, called the Challenger Deep,
right here on this map just about 300 kilometers
southwest of Guam Island. However, it is believed that
there are almost certainly even deeper parts of the
ocean than this that just haven’t been discovered yet. It wasn’t until
1997 after all that the Sirena Deep was discovered
with a depth of 10,732 meters, making it the second deepest
known point in the ocean. It is estimated that only
about 5% of the ocean’s floor has been accurately mapped,
leaving the other 95% to be currently a mystery. It may be only a matter of
time before an even deeper part of our ocean is found. And who knows what we
may discover there. So thank you for taking the

  2. 3,800 Meters Titanic?…Damn That would've took a long time to get down there but they discovered it soo..

  3. 袧懈 褋谢芯胁邪 薪械 锌芯薪褟谢, 薪芯 薪邪 胁褋褟泻懈泄 褋谢褍褔邪泄 锌芯写褉芯褔懈谢.

  4. I want to know the reasons to dislike this information!!!

    Who dislike – either they are aliens or bludy bhenchod

  5. how to go at bottom of mariana trench and live forever
    first step
    make an machine that can go bottom of mariana trench
    second step
    put soil sand and magma block
    third step
    just put sponge
    fourth step
    build a house

  6. What鈥檚 crazy is I think under the ocean floor is another city underneath and it kinda uses the floor as like the ceiling if it makes sense

  7. This is why i think we should stay in our fishbowl. We haven't even figured out whats on our own planet, how can we go out there when we have more than enough mystery here.

  8. Everyone else when the window breaks:its ok stay calm

    Me:GET ME OUT OF HERE I DID NOT WANT TO COME HERE AHHHHHHHHHH!!

  9. I sometimes ask myself, what if I get teleported in the middle of the Pacific Ocean… while walking down the street

  10. And if you reach the depth of 11,000 meter you will reach bikini bottom oh wait… The sea monsters that he talked about are lower than this depth which is when spongebob lost in the bus ride and went to it.. I think bikini bottom is at 5000 or 6000 meters depth

  11. Why not talking about the transparent fishes and those who create their own light :(? I really loved the video tho!!
