However, this paradise has a dark side --

The infamous bermuda triangle.

♪

[ thunder rumbling ]

For centuries, the bermuda triangle has struck fear

In the hearts of sailors

And gobbled up hundreds of ships.

Why have these vessels been lost at sea?

This mythic section of the atlantic,

Also known as the devil's triangle,

Fascinated our grandfather jacques cousteau.

It stretches from bermuda to miami to puerto rico,

About a half-million square miles of ocean.

It is said that hundreds of planes

And vessels have vanished in the area.

Only a small portion of them have ever been recovered.

The majority?

Found in the water surrounding bermuda.

♪

Yeah, the bermuda triangle is such a thing of legends.

Look at this article here.

"another unsolved mystery of the sea."

The key word here is "another."

It just goes on and on.

But it's not just the number of shipwrecks.

It's the fact that they seemingly disappeared.

No wreckage, no human remains.

Céline: The more common suspects include frequent hurricanes,

Treacherous reefs, and even massive deposits of magnetite,

Which could send compasses haywire.

Other theories abound.

They range from, you know, aliens coming down

And sucking up the ships to sea monsters

To this weird time warp possibility.

You know, there are a lot of people that were lost at sea,

And at the end of the day,

If we can find even one of these shipwrecks

And bring closure to those people who had lost loved ones,

I think right then and there

That would be validation enough to do it.

So fabien and I have come to bermuda

To follow up on a new lead,

A possible ship that has been discovered just on the edge

Of bermuda's outer-reef system.

♪

Céline: The south west breaker is notoriously

Difficult to explore.

A jagged reef lies just beneath the surface of the water.

Inclement weather can make navigation next to impossible

And no accurate maps exist of the constantly shifting reef.

It's the perfect hiding spot for a shipwreck.

I'm conscious of the fact that so many have tried

And failed to crack the case.

We're gonna come at it with some fresh eyes

And some new technology.

Having this arsenal of underwater

Investigative tools at our disposal,

We may be able to gather more clues

As to why so many ships in the bermuda triangle

Disappeared without a trace.

Céline: Our first stop is a visit with the person who tipped us off

To a potentially historical find --

Evidence to one of the bermuda triangle's missing ships.

Fabien: The bermuda triangle is something that everyone knows

And everyone theorizes about.

Why are there so many shipwrecks in the bermuda triangle?

I think a lot of the ideas -- you know, of a sea monster

Coming up and gobbling ships or an alien coming down.

-Yeah. -All of it seems --

I don't know, a little bit far-fetched.

But there has to be a plausible theory

As to why there are so many shipwrecks that have been found

And why so many ships have disappeared

That have not been found.

That's what I'm really curious about.

I love legend and lore.

I love discovering the facts behind all that

And really uncovering the reality of something

Like a shipwreck because a lot of times

It's much more interesting than the legend itself.

Céline: Philippe rouja is bermuda's custodian of historic wrecks...

Good to see you, too. Welcome.

Céline: ...And an old friend of the family.

My dad came here, I think, in '49.

So soon after -- well, a couple of years after world war ii.

And when the cousteaus came, they used my father's boat

To go looking for shipwrecks.

You know, people have been looking for shipwrecks

Since there was a shipwreck.

These reefs explain the shipwrecks that you have found.

Right. Right.

What about all of those ships that have disappeared

In the bermuda triangle that we haven't found?

[ ship thuds, screeches ]

Rouja: One of the theories is that, as they turn to get away,

They're dealing with the problems they've had,

Like if you've breached the hull or your masts are broken,

Et cetera, the weather's still terrible.

And you leave, and you sink on the way out.

[ rumbling ]

Those are the wrecks we don't know about.

Because they're too deep,

And we're on the top of mt. Everest here.

Yeah. It's just underwater.

Céline: There are many unknowns to this story,

But one thing we know for sure,

Our grandfather was really intrigued

By the mysteries of the bermuda triangle,

And people here remember him.

We want to restore some of those connections

With people like philippe

And continue the legacy of exploration.

I heard rumors that you guys found something.

Well, it wasn't me. It was actually chris gauntlett.

He's the reason we're here.

We're at his dive shop right now.

-Hey, chris. -Hey, guys.

Céline: Until now, chris's find

Has been a closely guarded secret.

Well, at the beginning, you don't tell anybody.

You sort of have a think about how you want to approach it,

And who you want to approach.

Tell us about this thing you found underwater.

Okay. We were doing a training dive in about 90 to 110.

We came to this object.

I didn't have a camera with me,

And I didn't have time to have a good look at it.

What exactly did you see?

It's an elongated piece,

Maybe 20 feet long. Hm.

And looking at it -- well, what I first thought it was

Was a torpedo, but it isn't a torpedo.

That would have been fun, too.

Doesn't seem to me to be anything like, for example,

Cable, which we might expect to find bits of,

So that's where this whole discussion kicked off

And how we came around to, well, what if it's something else?

Potentially part of a mast.

Céline: Chris, you think you can find it again?

Yeah, we can give it a shot.

Céline: Because the bermuda seamount

Is set at an incredibly steep angle,

It's entirely probable that this mast sits near a precipice

Located directly overhead

The location of the missing hull

And potentially many other lost vessels.

This is big.

If this mast really does belong to one of the lost ships,

It could potentially lead us

To an entire graveyard of shipwrecks.

♪

If we're able to explore these wrecks ourselves,

It might help us understand, at long last,

Why so many perished in the legendary bermuda triangle.

Chris is the only one who knows the approximate location,

Thanks to closely guarded gps coordinates.

In on the secret is robert carmichael,

An expert in using technology to find lost shipwrecks.

♪

Céline: Why do you keep those gps points close to chest?

It's large, and it's a heavy object,

So we're not worried about somebody moving it,

But we just want to make sure that nobody goes out there

To dive on it until we establish for sure what it is.

Céline: Unfortunately, his gps coordinates

Are only an estimate.

The dive that we did -- we marked the position

Where I came to the surface.

So there could have been a little drift off

As I was coming up to the surface

From where the object was.

Céline: He puts the search area at five square miles.

That's why, instead of donning dive gear,

We'll be relying on some extra horsepower.

Oh, wow.

So this is it -- the r.O.V. Yeah.

So an r.O.V. Is a remote operated vehicle.

It's really an underwater drone,

Is what it is, that's flown and piloted

By a small tether and a compact control system

That looks much like a video game.

Céline: We're at the spot where chris thought he saw a mast

Or something that looked like it.

It is the first clue that brought us here,

So we're gonna deploy the r.O.V. To check it out,

See if we can find it again,

Van alphen: The issue we have now is, of course,

That we are just at the aft-end of a storm --

A lot of wind, and the clouds are extremely gray.

So they're not letting a lot of light in.

And we need to find the key aspects of this

That make this a reef fingerprint.

The most effective point of view is gonna be this aerial.

We wanna basically find this patch of sand here.

It's gonna be our best indicator.

The next step is we send the drone up.

And this is what we're looking for, here...

And on the right-hand side.

Okay, let's ready the drone.

Fabien: Using a camera-mounted drone

To locate a world war I british warship?

Our grandfather would've loved this.

I wonder what he would've done with such a powerful tool.

For us, it feels like we're tantalizingly close

To finding the valerian's final resting place.

Here, that's the first half of what we think is the anomaly.

Keep going. That could be one there.

There should be something coming out just here.

I see another patch there, yeah.

Look at that.

There's that, right here! Right here!

All right, yep.

That might be the sand hole, right there.

Yep. Right there, yep.

[ beeping ]

Well, this is very exciting because we've finally identified

The coral reef fingerprint from the drone, from the air.

Now we need to put on our dive gear

And really go down there and check it out.

That'll just make the clamp go down.

To be the first to lay eyes on the valerian --

If this is indeed the valerian -- would be very exciting.

It went down almost 100 years ago.

Nobody has seen it since.

If we can get our hands on this wreck,

It might give us clues as to why she went down

And why so many other wrecks have disappeared

In the bermuda triangle.

Céline: We did a thorough search of the target area.

Side-scan sonar, snorkeling, diving, r.O.V. --

Even with the greatest technology,

We weren't able to find anything.

And it's just a really good reminder

How vast the ocean is.

How'd it go? [ exhales ]

Yeah, it was very pretty down there.

Didn't see anything.

There's no doubt we were in the right spot.

We saw all the features.

But there's nothing down there.

♪

We had this great hit.

I mean, this sonar, it looked like a vessel.

I mean, it just looked so perfect. Yeah.

Let's not forget robert identified this area

As potentially where the valerian had gone down.

Yeah. And we, you know --

We've only explored 25% of that, at most.

Mm-hmm.

Which means there's still a lot left to explore.

I wish we had more time to do it.

So even though we didn't find what we were looking for,

I think that was a pretty amazing dive.

Oh, to quote my grandfather -- our grandfather...

Thank you. [ laughter ]

..."if I knew what I was going to find,

I wouldn't bother going." that's right.

We can definitely say that this spot, um,

Doesn't hold the shipwreck.

But I'm wondering what's just over there.

I bet you it's not far. Yeah.

♪

Fabien: There's a reason why we've only explored

Less than 5% of our ocean world to date.

It is a treacherous place.

It is a mysterious place.

It's a place that holds its secrets tight.

That's exactly what tantalizes explorers,

And gets us really addicted to the adventure itself.
