Submergence

Some of the most common pathways

of energy production in microorganisms,

who live along the hydrothermal vents,

are oxidation or reduction of sulfur compounds.

The most common electron donor

along the vents is hydrogen sulfide,

making oxidation of sulfur containing compounds,

the base of the food web in this environment.

The microorganisms capable of oxidizing

or reducing sulfur compounds,

show amazing diversity.

Over 161 gram-negative sulfur-oxidizing bacteria species

have been found to inhabit the hydrothermal vents.

Bacteria in this environment are often thought of as all being autotrophs,

but of these 161 species,

over 97% are also capable of heterotrophic growth.

In addition, 37% perform fermentation.

Furthermore, the sulfate reducers known to be present,

include at least nine different genera, including gram-negative...

Yeah, I see.

I understand why.

No, to us it'd make a huge difference.

She'll be out soon.

You had enough?

While most are rod shaped...

They want us on the boat now for a team debriefing.

Can I get in the tank next time?

That's dangerous.

Each suit is designed specifically for

- each aquanaut, so... - Thank you, Paul,

but you don't have to indulge her every whim.

Thank you, Paul.

Why do you torture him like that?

He's too young to defend himself.

I'll race you.

- No. - Come on now.

No, I...

I don't like you.

Okay, I just want to go over the order of the dives,

so that you can communicate with each other

about who can help log,

as some of you will be prepping and not available to log.

All right?

We start from here, so Jonas and Rene are up first,

- Lucky you. - with Etienne as the pilot,

for the first dive in the Cadiz Gulf.

Then we're going to hug the coastline,

going west of Ireland and Britain into the Norwegian Sea.

There, Gustavo and Maria are next,

with Frank piloting around the Faroe Island.

Frank, who is also taking Annie and Mark down,

here near Iceland where we'll spend the most time,

and do several dives, okay?

It's a complete reversal, I'm sorry.

And then, our deepest dive,

Thumbs and Danny, are last, around Jan Mayen,

with Etienne as a pilot, okay?

There are definite advantages in going last.

They're gonna be logging and not prepping,

and the sub will be tested.

I'm not thinking about that.

Then what's up?

I realized I've never been lonely before.

Hmm. Welcome to the planet.

It's possible there's no service where he is.

He's working in Northern Kenya, right?

Or he just stopped calling,

stopped being interested.

Impossible.

He's just stuck somewhere without reception.

For a month.

Yes.

Why not?

Don't go near him, boy!

Next.

The Monk by the Sea is and...

...The Berlin Academy exhibition of 1810.

What do you got for us?

I have a bona fide source,

willing to give up an to an operational bomb unit in Europe.

- They want to hit train stations. - Where's the link?

In Southern Somalia.

What's on the table for the source?

British passport, we want him.

We'll find him, we'll get him.

He's my source, so I'm going there alone.

Somalia is not a good idea, J.

I know.

Check this out.

We are talking about bombs all over Europe.

If there's even a chance we can get out in front of that, we have to take it.

We don't know who they are, where they are.

Their whole pipeline of intelligence

and soldiers waiting to stream in.

You don't even know what faction is in charge in Kismayo right now.

Well, I was hoping you could help me out with who's in charge there.

Oh, come on, James, this isn't Afghanistan.

So, how are you getting in?

Small plane.

I'll use my water engineer alias.

I'll meet my contact at Kismayo airport.

So, you're mister water expert and you're gonna dig up some wells?

In the tooth again, that's the safest.

Yeah, I'll activate it once I'm there. Same as last time.

Don't let them know you speak Arabic, J.

Guys, do me a favor and just tell me something

that's gonna help me, would you?

Fuck!

Yeah? Okay.

Wait, we've got something for you.

Look at the picture.

You must remember this guy, Yusef Mohamud al-Afghani.

Yeah.

He was with Osama in 2001, wasn't he?

Yeah, apparently he's in Somalia now.

We'll get you intel on him, whatever we dig up.

Give us a few days, J, we'll contact you on a safe line.

Hey!

Hi. You came yourself.

For you, Madame Flinders, of course.

Oh, so good to be back.

Thank you.

Evening.

What kind of whiskey do you have?

I've got a good Japanese one.

Konichiwa, let's go Japanese.

- You play rugby? - I used to.

- What's your name? - Marcel.

- Why did you stop, Marcel? - Oh, you know,

- I just broke my neck. - Yeah, stick that on room 12, please.

- Okay. - See you later.

Your white wine, Madame.

Thank you, Marcel.

Hey.

Good Morning.

Good Morning.

- You're English? - British, Scottish British.

Danny, Danny Flinders.

James More.

- Will I see you later? - Yeah, I'd like that!

Oh.

I think you're following me.

Or you're following me in advance.

Tricky.

Mr. More, the newspaper you wanted.

Thank you, Beatrice.

You're definitely following me.

I haven't even had a chance to shower yet.

I love the smell of sweat.

- I have to do some work. - Is this your room?

- Lunch? - Would 1:30 be too late?

No.

Free-living chemoautotrophic

microorganisms at hydrothermal vents.

We integrated the analyses of IPL diversity and delta13C values,

delta13C lipid with 16S RNA gene-based--

Yes?

I've come to take you to lunch.

It's open.

Carry on, Professor.

How did you know I was a professor?

I looked at your name on the letter you picked up this morning.

What are you a professor of?

Take a guess.

Um...

Music?

Nope.

Do you mind turning it down a little bit?

It's awfully loud in here.

I mean, you couldn't really hear me...

knock on the door even, so...

- Thank you, Law? - Please.

- Anthropology? - Wrong again.

Well just, tell me then.

I apply mathematics to the study of life in the ocean.

You're an oceanographer?

There's no such discipline as oceanography.

I'm a bio-mathematician.

It's the working of the science to whatever is in the sea.

Or at the bottom of it.

Precisely.

It's quite rude, just sitting there, watching me.

Insisting that we eat something?

I know, it's entirely unreasonable.

So, what ocean is your favorite?

It has to be that one, the Atlantic.

Okay.

Carry on.

- About? - The sea.

I feel certain it's going to tell me all about you.

All right, then, um...

close your eyes.

You're determined not to let me eat, aren't you?

Close them.

The ocean has five layers.

- Five. - Are you going to cooperate?

Mm-hm.

- I want you to picture this. - Okay.

Yes, it has five layers and the first one is epipelagic.

It contains all the plant life and coral reefs.
