Shadowing Practice: Nothing About The Mariana Trench Is Normal... Here's Why - Learn English Speaking with Video

1
Imagine you're going down to the bottom of the Mariana Trench in a full military-grade diving suit.
2
You might think all you'd see are some tiny creatures or just straight darkness, but what would actually happen is your lungs would implode before you even reach the bottom.
3
You're cooked.
4
The pressure in the Mariana Trench is the highest in the entire world, more than a thousand times the pressure at the surface,
5
and even the most advanced military-grade diving suit would have zero chance of saving you from collapsing in on yourself.
6
And so only logically, there should be essentially nothing capable of surviving here, right?
7
Well, if you know anything about the horrors of the deep ocean, you'd already know this isn't what happens.
8
In fact, most of the deep ocean doesn't just have life.
9
It has some of the most gigantic life on Earth.
10
You have massive sharks that have been alive at the same time Isaac Newton was, squids bigger than buses, and all the other real-life gigantism horrors you could imagine.
11
But the Mariana Trench isn't just the deep ocean, it's the deepest point on the entire Earth.
12
So what actually exists all the way down there?
13
To understand the Mariana Trench, we first have to take a look at where it even starts.
14
The Mariana Trench is around 10,984 meters deep,
15
but this is measured from the ocean surface the actual trench starts about 5,000 meters below sea level, which is the upper rim of the trench.
16
Everything above the Mariana Trench is actually super.. normal.
17
Which would make sense since it's just the open ocean above.
18
In fact, anything floating there, whether it's a fish or a human, wouldn't even know they're above the deepest spot in the entire world.
19
The trench is so deep that if you took Mount Everest and plunged it upside down into the middle of the ocean,
20
its tip would still fall about 7,000 feet short of the trench's bottom, called the Challenger Deep.
21
And this place is so impossibly remote that only 22 people in all of human history have ever reached it.
22
Which to put in comparison, even more people have flown to the moon.
23
So what would it take to get to the bottom?
24
Well, to get there, you'd have to pass through every layer of the ocean.
25
Unfortunately, the Epipelagic Zone is the first layer, and the only zone you could even make it into.
26
It's about 200 meters, and you could survive the top part of it since that extends towards the surface.
27
But even getting to the bottom of the zone is close to impossible.
28
After about 200 meters, you'd reach the Mesopelagic Zone, the same depth where the deepest freedive record ever was set at 214 meters with a wetsuit.
29
This is only the top of the Mesopelagic Zone, though, and no human freediving would ever be capable of reaching the bottom of the zone, which goes to around 1,000 meters.
30
The pressure here is around 100 times heavier than at the surface, and you'd probably die instantly.
31
Kinda scary since this is only the second zone, but I guess that's a deep ocean for you.
32
Below there is the bathypelagic zone, starting around a thousand meters and stretching down to about 4,000.
33
Ignoring the pressure that would have crushed you long ago, if you were somehow alive down here, you'd be completely blind, since effectively zero light can reach,
34
and you'd also probably freeze to death, and the pressure is enough to crush steel.
35
So you're probably wondering, how can this get even worse?
36
Well, as I mentioned before, the Mariana Trench only actually starts at about 5,000 meters below sea level.
37
We haven't even reached it yet.
38
Past the bathopelagic zone is the abyssopelagic zone, which spans from about 4,000 to 6,000 meters deep.
39
This is actually my favorite zone in the whole ocean, not only because the abyss sounds really cool, but also because it has some of the freakiest animals possible.
40
This zone should actually be the bottom of the ocean because for almost all of the ocean, this is the bottom.
41
But unfortunately for those afraid of the deep sea, this zone is only where the trench begins.
42
At this point, the pressure is over 600 times what it was at the surface.
43
Not that that really makes any difference to you since you've already been crushed thousands of meters ago.
44
At the top of this zone, you might find the Stygia medusa gigantea, which if you couldn't tell by the name, is gigantea.
45
This is a massive species of jellyfish, specifically created by deep sea gigantism.
46
It's over 10 meters across, including its strange tentacles that look like ribbons.
47
There's only been about 100 sightings in the past 100 years of this giant phantom jelly.
48
And because of that, we don't know much about their average weights or upper limits, but it's estimated to be around 150 pounds.
49
They're definitely large, but as most jellyfish go, they're not too heavy, at least compared to other giant creatures.
50
Oddly enough, they don't sting either.
51
They use the ribbon tentacles to slowly trap prey for small things that swim by.
52
It's kind of like fly tape, but just the deep sea gigantism version of it.
53
But at the very bottom of the abyssal zone is one of the largest squids in the world.
54
And while you probably think I'm talking about the famous giant squid that I know I usually can't shut up about, you actually won't see them at all here.
55
The abyssal zone is oddly enough too deep for the giant squid, and they can only reach up to mid-bathaplegic waters.
56
And while you might also think of the colossal squid, which do actually live in the upper abyssal zone, they wouldn't be in the Mariana Trench, since they stick to the Antarctic waters only.
57
But what you would find here is something even stranger.
58
The magma pinna, also known as the big fin squid.
59
If you saw our video on the creepiest squids, you'd know that, at least in my opinion, this is by far the creepiest squid in the world.
60
Well, that we currently know of.
61
While it's unlikely to be as dangerous as an actual tank like a colossal squid, it's just plain unsettling to look at.
62
I'm not fully sure why its tentacles are stretched like that, why it sometimes just hovers, and honestly, most marine biologists don't really know either.
63
They're usually so deep and unbelievably rare that we can't even study them.
64
Most of what we know is usually from juveniles.
65
They stretch about 25 feet long with those weird elbowed arms that just hang.
66
The most likely reason is that they're used to catching smaller things passing by, but we've never actually caught a live adult specimen.
67
These squids live so deep that sometimes they even reach the upper haddle zone, which is so deep that it's usually too deadly for even most normal squids.
68
And yes, this creature is another example of the deep sea gigantism effect.
69
It doesn't just have to turn big things bigger though.
70
It can also affect smaller things, like isopods.
71
The giant isopod is the same family as normal pill bugs, but instead of being a few millimeters, they're closer to 20 inches across.
72
Smaller than people, sure, but massive for isopods.
73
They're usually near the upper abyssal though, and while you might think it could be possible for them to go deeper into the Haddle Zone, it's not super likely.
74
Plus, it wouldn't benefit them either, because the Haddle Zone is probably the worst place you could live on Earth.
75
This place is so remote that it doesn't even exist in most parts of the ocean, and only in deep ocean trenches.
76
And of course, that includes the Mariana Trench.
77
It stretches from 6,000 meters all the way down to 11,000.
78
And the only reason it doesn't stretch more is because the Challenger Deep is already the deepest part of the ocean.
79
The pressure is so deep that it's over a thousand times the pressure at sea level.
80
And I'd usually give some wacky comparison, but I don't really think you could actually imagine what it's
81
like to have the entire weight of an adult African elephant standing on every single square inch of your body.
82
Interestingly, you might expect there to be some of the craziest giants you've ever seen there.
83
But that's not really the case.
84
The Haddle Zone is so unbelievably hard to survive in, that deep sea gigantism actually starts to reach its limit.
85
Things get bigger and bigger, until they don't.
86
The more body you have, the more pressure there is crushing every square inch of it.
87
A small organism can handle that better
88
because it has less surface area for the force to act on and fewer internal parts that can collapse or malfunction.
89
As well as probably the more important issue, there's barely anything even here food is so limited that you literally can't even get enough at some point.
90
It's strange to think, and most channels don't usually cover this because they like to play up the deep sea gigantism effect.
91
But the Haddle Zone is basically the end of deep sea gigantism, and effectively, where the deepest sea shrinking starts.
92
Animals don't just get infinitely bigger, and while there may be some undiscovered squid bigger than a giant squid elsewhere in the ocean,
93
it's extremely unlikely that it lives in the deeper Haddle Zone.
94
It's just simply too deep.
95
So what actually lives here?
96
One of the most well-known is the Mariana snailfish, the deepest living fish ever discovered.
97
And no, it's not a snail, it's a fish.
98
It's small, almost translucent, with no scales, and a body so soft, it would collapse under normal pressure at the surface.
99
But down here, that jelly-like body is perfect.
100
It bends instead of breaking, letting it survive more than 8,000 meters deep they're still about a foot long too.
101
There are amphipods too, which are shrimp-like crustaceans that can survive all the way down to the Challenger Deep.
102
Some of them have special proteins that stop their cell membranes from collapsing under pressure.
103
Others even eat bits of plastic that have somehow made it this far down.
104
There are also xenophiafors, which are giant single-celled organisms that live right on the trench floor.
105
They can grow up to four inches wide, making them some of the largest single cells on Earth.
106
Strangely, xenophorefors might actually be important for life down there.
107
They create little micro habits out of sand and minerals, providing shelter for other small organisms in an otherwise barren wasteland.
108
So even though they're single-celled, they kind of act like ecosystem builders for the deep trenches.
109
Not really as epic as giant squids, but you don't get much better this deep.
110
Besides that, there are worms, microbes, and other tiny scavengers that feed on marine snow, flakes of dead plankton, feces,
111
and organic dust falling from above.
112
Life in the Haddle Zone isn't really some cool zone of giant monsters battling each other beneath the water.
113
It's basically just, you die or you barely survive.
114
And that's why the Abyssal Zone is my favorite.
115
More cool monsters are there.
116
But where else does the Haddle Zone exist besides the Mariana Trench?
117
Well, the Haddle Zone is usually created when the Abyssal Plane cracks open due to immense tectonic activities and forms ocean trenches,
118
just like the Mariana Trench.
119
There are about 20 major ocean trenches around the world, mostly found in the Pacific Ocean.
120
The most famous ones are the Tonga Trench, the Philippine Trench, and of course, the Mariana Trench.
121
But if it's basically a death sentence to even exist there, how do we know anything that's down there?
122
Well, the short answer is, we barely do.
123
The only reason we know anything about the Haddle Zone is because of a few extremely rare and insanely difficult missions.
124
Missions with the most advanced submarines and people with the most advanced guts to actually get in one.
125
Most submarines can't even come close to reaching the bottom of the Mariana Trench.
126
Even advanced military subs like nuclear attack submarines max at 600 meters.
127
You're not making it to 6,000, yet alone 11,000.
128
here are designed basically to be a pressure-proof capsule and not much else.
129
The first humans to ever make it all the way down were Jackie's Picard and Don Walsh in 1960, inside a submersible called the Tresel.
130
Imagine being in a steel ball barely big enough for two people, lowered almost 11 kilometers into total darkness,
131
not even sure if the hole would hold, because it's 1960s tech.
132
At around 10,900 meters deep, one of their outer windows cracked under the pressure, which personally would have made me pee myself, but somehow they made it.
133
They stayed at the bottom for about 20 minutes before beginning the long, silent rise back to the surface, probably staring at that crack the entire time.
134
After that, no one went back for more than 50 years, because who would honestly want to even go down there?
135
The next major descent didn't happen until 2012, when James Cameron, the same dude who directed Titanic and Avatar, piloted a one-man sub called the Deep Sea Challenger.
136
Not the most unique name, I guess, but he did become the first person to reach the Challenger Deep solo.
137
His vessel was shaped like a tornado, covered in bright green plating and specifically designed to just go deep.
138
He described the bottom as a completely alien world.
139
Flat, desolate, and with fine sediment that looked like grey powder and no sign of big animals anywhere.
140
Which would line up with the end of deep sea gigantism that I just mentioned.
141
In 2019 though, a guy named Victor Vescovo broke the depth record again with his sub-DSV limiting factor,
142
reaching nearly 10,928 meters.
143
Which granted is only about 20 meters deeper than James Cameron did, but I guess he really wanted that record.
144
Unlike earlier dives, his mission wasn't just to go down and come back up, it was to explore.
145
And probably also to beat James Cameron's record, but he didn't say that.
146
He spent hours mapping the sea floor and filming some of the most extreme creatures ever caught on camera.
147
He again found plastic waste at the very bottom.
148
Most of what we know today doesn't actually come from humans going down there though.
149
It comes from ROVs and landers.
150
Scientists drop them into the trench and they slowly sink for hours before finally reaching the bottom.
151
These machines carry cameras, sensors, and bait traps, and sometimes even robotic arms that can collect samples.
152
The pressure resistant casings on these cameras are made from titanium and thick glass, and if they fail, they implode instantly.
153
And even with all that tech, the success rate is low.
154
The trenches are pitch black, freezing cold, and full of fine sediment that clouds up instantly when disturbed.
155
Most of the footage we get is shaky, grainy, and lasts only minutes, but it's enough to reveal that the Haddle Zone isn't completely dead.
156
Most new missions end up revealing something new, because it's just so hard to find things when you're down there.
157
But so far we haven't encountered any super giants down in the Haddle Zone.
158
And sorry for any lovers of sea monsters, probably never will.
159
Trenches like the Mariana Trench aren't really meant to be the deep ocean.
160
They're the deepest parts of the ocean.
161
Places so inhospitable that they're only created by tectonics in the earth.
162
They weren't even designed to store the monsters of the abyss.
163
They just store anything that can endure.
164
Thank you guys for watching.

Gölgeleme Tekniği Nedir?
Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
