And currently we're working on oxygen oxygen delivery on site.

The technology for oxygen delivery is not new.

The first limitation is the oxygen oxygen toxicity.

Liquid oxygen

Love is like oxygen.

Oxygen and hydrogen make water.

The primary purpose of the gas system is to provide oxygen, to replenish the oxygen that your body consumes.

Photosynthesis is modulated by oxygen, and we have an oxygen insensitive hydrogenase that we think will totally change this process.

It's called a carbon oxygen dwarf.

She tripped over her oxygen tank.

Water consists of hydrogen and oxygen.

So, in this room, there's 20 percent oxygen or so, and if we reduce the oxygen concentration, we will all be dead.

And because you can't bind the oxygen, maybe you wouldn't consume it, and then maybe it would reduce your demand for oxygen.

It inhales oxygen, just like we do.

We had lost seven tons of oxygen.

Stromatolites were the first to exhale oxygen.

It grew as light and oxygen increased.

Its oxygen consumption rate fell by tenfold.

I have an oxygen hose connected here.

The oxygen tanks didn't quite work right.

You get a hypoxia, or a lower oxygen.

Oxygen, hydrogen and zinc have their own signature.

I was so fascinated by that Oxygen commercial.

It's not hard it's just three oxygen atoms.

There's a built in oxygen concentrator down there.

Because of the movement I was wasting oxygen.

Trees give off oxygen and absorb carbon dioxide.

Water is made up of oxygen and hydrogen.

We're all breathing air right now. Air is a mixture of oxygen and nitrogen, about 20 percent oxygen. About 80 percent nitrogen is in our lungs.

In fact, that one is a carbon oxygen dwarf.

He had an oxygen toxicity seizure and he drowned.

In this case, you're seeing oxygen bubbles come out.

We're actually measuring its oxygen consumption, its energy consumption.

We put water over its gills, give it oxygen.

But, if we only had an oxygen gas supply cylinder we wouldn't be able to go very deep, because we'd run into oxygen toxicity very, very quickly.

We also have a second oxygen cylinder, that's solely as a back up in case there's a problem with our first oxygen supply we can continue to breathe.

And it was time for us to put oxygen in.

That's bad news for coral reefs and oxygen producing plankton.

At 67 percent oxygen saturation, the normal is about 97.

If you take nitrogen out, what's left? Oxygen, pretty much.

And in the process they use up all the oxygen, and in using up all the oxygen they make the environment utterly lethal for anything that can't swim away.

But in this case, we measured the different isotopes of oxygen.
