I'm taking my aqualung and my snorkel.

There is a problem with scuba though, in that it imposes some limitations on how deep you can go, and it turns out that depth is about 200 feet.

Some men put on an aqualung

The only creatures that have got conscious control of their breath are the diving animals and the diving birds.

Provided with a diving autonomous compressed air

He's starting to breathe, Bill. I'll switch off the ventilator.

I sent up and he seemed to have understood.

444. The need for obtaining better information about the ocean floor has led to recent advances in diving apparatus, submersibles, remotely operated vehicles (ROVs) and self propelled autonomous underwater vehicles (AUVs).

Your breathing equipment.

Mobile emergency respirator Patient monitor

One creation resembled scuba diving gear complete with snorkel and goggles, while another looked like a melted ice cream cone.

Scuba divers can't get there, submarines go right on past it.

I've made hundreds of dives in submersibles.

Falco leaves his diving, We are moving forward

Either hurry up or get me a snorkel.

Then the pneumograph is fastened about the subject's chest... and we record the changes in the respiration.

I don t know of any other submersible, or even remote, that just takes advantage that this is a three dimensional space.

We need new deep diving submarines.

I put my snorkel in my mouth, and I rolled over the side of the Zodiac into the water.

This is in China. This girl needed a breathing apparatus.

And I've dived in deep sea submersibles around the world.

There's a chemical filter in there that pulls the carbon dioxide out of the breathing gas so that, when it comes back to us to breathe again, it's safe to breathe again.

In, out.

When I saw him take off his mask, I realized that I had lost my mind.

This is us chasing it in the submersible.

For this the Germans had three powerful weapons, the magnetic mine, the Uboat, and the surface raider.

The recently developed AUVs are computer guided, untethered vehicles, capable of overcoming many of these problems, but are expensive.

This, I think, represents one of the most beautiful classic submersibles built.

If you look at that sub, you ll see a sphere.

If a rebreather isn't available, you can use this device.

Unable to breathe on her own, she was put on a ventilator.

Purging is basically hyperventilating.

On the other hand, cable operated submerged systems in deep water are encountering certain problems either reduced speed, as in the case of ROVs on the seabed, or reduced accuracy of positioning, as in the case of deep tow vehicles operating in the water column.

And of course there're multiple displays, to get the information to the diver.

So the sub that was outside last year this is the one.

And the breath, the breath is the captain of that vessel.

BJ One of them is breath, and it kind of breathes.

Breath Noise

There now. Breathe deep.

Now breathe deeply.

Deeply.

And again.

Now cough.

Cough. Breathe.

Breathe in.
