渦巻に飲まれたら!

00:00
Imagine, you’re on vacation.
00:04
No, you’re not interested in beachside hangouts or big city tourism.
00:09
You’ve decided to avoid the crowds and go on a quiet adventure to the mountainous landscapes
00:15
of Scandinavia.
00:16
The weather is calm, the nature around you is breathtaking, and this quaint little getaway
00:21
calls for one thing: a nice boat trip down a quiet stream to really take in the views.
00:28
As you venture out from the land, not a single wave disturbs your vessel.
00:33
Nothing speaks of the danger you’re approaching so unknowingly.
00:38
But just as you close your eyes and take in a deep breath of fresh mountain air, you suddenly
00:43
feel your boat take a turn.
00:46
Whatever’s pulling you off course only gets stronger, and your heart starts racing.
00:51
No matter how much you paddle, all your attempts to get the boat under control are in vain.
00:56
That’s when you see it…
00:58
All the water around you has come alive.
01:01
It’s not a smooth peaceful surface anymore, but a bubbling foamy vortex.
01:06
What’s worse, it’s dragging you right into the hungry mouth of a giant beast straight
01:11
from ancient myths!
01:13
And it has a name: the Saltstraumen Maelstrom…
01:17
With a name like that, you might be imagining something like the Kraken.
01:21
But, alas, you’ve found yourself being sucked into the world’s strongest whirlpool.
01:26
Phew!
01:27
Don’t need to battle any mythical sea monsters today!”
01:29
Hey, don’t let your guard down because you’re not off the hook just yet!
01:34
For centuries these whirlpools, or maelstroms, were a thing of legend.
01:38
There was no explanation for their existence and no power that could get an unfortunate
01:43
ship out of their trap.
01:45
One of the first and most well-known stories about this phenomenon is Homer’s Odyssey.
01:50
It describes a sea beast called Charybdis, a colossal monster, the only visible part
01:56
of which was just its mouth.
01:59
It opened its jaws so wide that it could swallow ships whole!
02:03
Inside the beast, there’s only darkness…
02:06
Is it possible that this image is just an early interpretation of a maelstrom?
02:11
Remember, people couldn’t explain what they were or why they existed, so they came up
02:16
with epic legends to explain the unknown.
02:19
But today, science has given us a better understanding of geological phenomena.
02:24
Still, that doesn’t mean whirlpools aren’t a fascinating example of nature’s awesome
02:29
power!
02:31
Whirlpools are bodies of spinning water that flows towards the center where two currents
02:35
smash into each other.
02:37
The result is the birth of a vortex.
02:40
If you look into the eye of the “beast” you’ll see something strange – the water
02:44
from one current wraps around the water from the other.
02:48
It’s like an intricate dance, both twisting and turning around each other.
02:53
In fact, this process is no different from simple mixing.
02:57
By nature, streams of water try to mix, but their force and speed make the whole process
03:04
much more difficult.
03:06
This is where turbulences come from.
03:08
Another thing that can collide with a current and lead to the creation of a whirlpool is
03:12
wind.
03:13
Now imagine when those two forces come together – wind and water currents whirling around
03:18
in one spot.
03:19
Yes, you get the strongest whirlpools out there!
03:24
The big ones are called maelstroms.
03:27
You might think of it like a vile watery tornado that goes underneath the sea’s surface,
03:32
but that’s far from reality.
03:34
The biggest ones are not fascinating because of their size, but more because they rarely
03:39
appear alone.
03:40
They’re more like a system of smaller whirlpools making the water look like nature itself decided
03:46
it’s laundry day!
03:47
Thus, we return to the king of them all: the Saltstraumen Maelstrom.
03:52
It’s situated on the northern coast of Norway near a town called Bodø.
03:56
Norway is famous for its coastline covered in rocky fjords.
04:00
Those are steep cliffs carved by the immense pressure of icy glaciers.
04:04
A little more than 2,000 years ago, Norway was completely covered in ice.
04:09
But as the climate changed, glaciers started to melt and move.
04:13
Their weight was enough to crush rocks and plow the land as they migrated.
04:18
This is how the Saltfjorden and Skjerstad Fjords were born.
04:22
Between them, a strait appeared – Saltstraumen.
04:25
This name can be translated as “salty stream”.
04:27
And that’s probably because every 6 hours, over 100 billion gallons of salty seawater
04:34
powers through the current in the strait at an impressive 25 mph.
04:40
As a result, the area fills with whirlpools 6 times a day.
04:44
Sometimes it’s just a couple of big maelstroms, and other days there are dozens of them.
04:49
Some can be almost 40 feet in diameter, enough to fit an entire school bus!
04:55
The biggest vortices can reach 16 feet deep, or about the length of your average pickup
05:00
truck.
05:01
So, can a thing like that cause any trouble?
05:03
Well, all I can say is you wouldn’t want to get in the water near such a monstrosity
05:09
on your own.
05:10
The current is ferocious enough to make any effort to swim away almost completely futile.
05:16
And a vortex this size will surely drag anyone underwater within seconds.
05:21
The water here is extremely cold too, so, yeah, getting sucked in would be a bad situation
05:27
to say the least!
05:28
On the other hand, the Saltstraumen Maelstorm poses little to no threat to boats or ships
05:33
nowadays.
05:34
Going through the strait is absolutely manageable even in a small motorboat – today’s engines
05:39
are powerful enough to escape the whirlpool’s grip.
05:43
And no matter how dangerous they are, maelstroms are still a sight to behold.
05:48
Bodø became a popular tourist spot because of them.
05:51
There’s a huge bridge going across the strait, and it’s now an observation point for awestruck
05:57
sightseers to witness the power that is the world’s strongest whirlpool.
06:02
Another huge maelstrom gained famed thanks to authors like Edgar Allan Poe and Jules
06:07
Verne.
06:08
It’s the Old Sow Whirlpool – the biggest maelstrom in the Western Hemisphere.
06:12
It’s located between Canada and the US, up near Dear Island, New Brunswick and Moose
06:18
Island, Maine.
06:19
The whirlpool is a lot bigger than any in Saltstraumen, but not nearly as fast.
06:24
Still, a swirling vortex of water 250 feet in diameter is nothing to scoff at!
06:31
But even with a mouth big enough to fit the wingspan of a 747 with room to spare, the
06:38
vortex itself is rarely visible because it moves as such low speeds.
06:43
Aw, disappointing…
06:45
Most of the time it looks more like something is lurking underwater.
06:48
Sometimes it even shoots weak fountains to the surface so it becomes bloated and unnaturally
06:54
still.
06:55
If you’re wondering why the whirlpool is called Old Sow, there’s a pretty funny story
07:00
behind that.
07:01
The constant roaring sound it makes reminded locals of a pig grumbling.
07:06
For the same reason, small whirlpools that appear around the big “sow” are called
07:11
her “piglets”!
07:12
I’ve already mentioned Homer, Poe, and Verne, so you can see just how often maelstroms find
07:18
their way into our culture.
07:20
Well, can’t forget about the Far East!
07:22
You ever admired beautiful works of Japanese ukiyo-e artists?
07:27
Their marine landscapes are exceptionally captivating.
07:31
One of such masters, Utagawa Hiroshige, once made a piece called “Naruto Whirlpool, Awa
07:37
Province”.
07:38
And guess what?
07:39
This whirlpool really exists!
07:41
As it often goes, this one is also located in a strait.
07:45
The current running through the islands of Naruto and Awaji flows at 12 mph.
07:51
When the spring tides begin, vortices here can be over 65 feet in diameter, which is
07:57
about as long as a bowling lane.
07:59
If you’re interested in having a peek, there is an observation point from a nearby bridge.
08:05
That alone is an incredible construction!
08:07
It’s over 5,300 feet long and looms over turbulent waters at a height of 135 feet!
08:15
There’s one more place I’d like to tell you about, and it’s the Gulf of Corryvreckan.
08:20
According to one Scottish myth, Cailleach Bheur, the goddess of winter, used the gulf
08:25
as a washtub for her plaid.
08:27
This is where Corryvreckan’s whirlpool allegedly originates from, if you’re into more mythical
08:33
explanations, of course!
08:34
It’s the second largest maelstrom in the world, and it calms down only for about an
08:39
hour or so a day.
08:41
But even without the whirlpool, the current running through this straight between the
08:45
Scottish islands of Jura and Scarba can go extremely fast.
08:49
So, imagine my surprise when I found out people actually try to swim across this thing!
08:55
They’re called “wild swimmers” and the Gulf of Corryvreckan is a hotspot for them.
09:00
Instead of simply hitting up the beach or community pool, these adrenaline chasers specifically
09:06
hunt for places as dangerous as possible to swim across!
09:09
Yeah, well, I bet many have won a Darwin Award for trying to swim over half a mile to make
09:15
it across this fast-moving strait!
09:18
As for those of us who live on the brighter side of life, I say we stick to admiring these
09:23
whirlpools from afar!
09:26
