And therefore we're way behind on protection.

Because we actually created a reality where six months later,

The other primary way is we go down with submersibles and remote operated vehicles.

I've made hundreds of dives in submersibles.

But mostly I'm entranced by it.

This makes for some pretty spectacular light shows.

So you can see what I was doing.

It's one of my favorite bathing suits.

But in the early days, the only way I could get to the bottom was to crawl into a submarine, a very small submarine, and go down to the bottom.

And this one is the deepest diving submarine in the world, operated by the Japanese government.

Brian Skerry took this shot. Thanks, Brian.

They also live deep.

Carter, this is ASDS.

That's not luminescence, that's reflected light from the gonads.

A.S.D.S., this is Carter.

I want to find out what's in this zone we know almost nothing about it.

We need more eyes on the process.

And Sylvia Earle and I were on an expedition in this submarine 20 years ago in Japan.

There's no connection to the surface apart from a pretty funky radio.

And the first thing you're going to see is a transect screen that is about a meter across.

It's got a lot of other light organs you can't see, but you'll see in here in a minute.

And we wound up going to the Bismark, and exploring it with robotic vehicles.

I've spent about 3,000 hours underwater, and 500 hours of that was in submersibles.

Bubblehead. A bubblehead!

Now I want to share with you a little video that I shot from a submersible.

And the first time I figured out that way was in this little single person submersible called Deep Rover.

Submarine, mr. Wayne. like a submarine. and the other device?

So, we wanted to accelerate this process.

The bad news is, this is a semi submersible run by drug cartels.

And I defy you to name any other branch of science that still depends on hundreds of year old technology.

Alvin and Sea Cliff and Cyana, and all the major deep submersibles we have, which are about eight.

Dive, Cookie.

A.S.D.S. has cut engines, commander.

This came out of hundreds of dives I have made, farting around in the dark using these platforms, and my impression that I saw more animals working from the submersible than I did with either of the remote operated vehicles.

That sparkle you're seeing is not luminescence, that's just electronic noise on these super intensified cameras.

The tripeight.

They didn't have the means to do it, so we created technology to do it.

The submarine's periscope was sticking right out of the water.

I hunt subs, you drive subs.

I've been a bioluminescence junky.

All right.

And it was the most surreal kind of deja vu experience I've ever had, because I would know before I turned a corner what was going to be there before the lights of the vehicle actually revealed it, because I had walked the set for months when we were making the movie.

She just rolled right away from underneath.

Divers... get the ladies, Sir.

You have 15 minutes.
