Three, they allow you to go deeper.

I'm going to take you on a deep dive.

I dove in a whole series of different deep diving submersibles.

But, if we want to go deeper, of course, we need another gas supply.

But, the point is that scuba divers generally stay less than 100 feet deep, and very rarely go much below this, at least, not with any kind of sanity.

So, to go deeper, most biologists have turned to submersibles.

Now, submersibles are great, wonderful things, but if you're going to spend 30,000 dollars a day to use one of these things, and it's capable of going 2,000 feet, you're sure not going to go farting around up here in a couple of hundred feet, you're going to go way, way, way, down deep.

The deeper you go, the loopier you get.

How was the deepsea diver?

Since my my first dive in a deep diving submersible, when I went down and turned out the lights and saw the fireworks displays, I've been a bioluminescence junky.

So let's take a deeper look.

It can dive to 500 feet, to where sunlight does not penetrate, and is equipped with powerful lights.

We need new deep diving submarines.

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.

Rather, we should grasp the potential that it holds for moving towards broader and deeper reforms.

And as you go deeper, that lovely, blue water you were launched in gives way to darker and darker blue.

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).

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

Down and as the sun gets brighter they go a little deeper, little deeper.

Compassion is rarely a solution, but it is always a sign of a deeper reality, of deeper human possibilities.

Now, the deeper you go underwater, the higher the pressure is.

I have to go. I have to jump in.

In some cases, cooperation will be much deeper.

There is depth records, where people go as deep as they can.

Now, when we started working deeper and digging deeper, we found that it's an illegal act.

Get down!

So, the bottom line is that almost all research using submersibles has taken place well below 500 feet.

And of course, if you were to down to where there's 15 times as much the deeper you go, the more exacerbating the problem becomes.

The semisubmerged shipwrecks They are useless. We have never seen anything well preserved less than 20m deep.

But you don't always have to go down to the depths of the ocean to see a light show like this.

New discoveries They are waiting for us in the world of silence.

And this rig was actually used for a dive of 300 feet.

The potentials indicated below were among the most important.

The result of it would give more hurt to the people The war goes on

We need helium, and the helium is what we really need to go deep.

We need deep diving subs, new technologies to explore the ocean.

I can't fly, either. What do you know about deepsea diving?

But what is really amazing, because of this deepness here, Emperor penguins can go down more than 500 meters and they can hold their breath for 23 minutes.

Whose color is deeper?

It goes much deeper than that.

And that's what we use to inject, as we start to do our deep dives.

For example, operational performance and survey capability of a new type of relatively inexpensive AUV has been demonstrated at a depth of 600 metres.

In late 1997, the development of a prototype, operable in water depth down to 2,000 metres, has begun and is planned to be operational in 2000.
