Oxygen, people.

When you shine light on them, you can see them bubbling.

I thought you had to go back to the hyperbaric chamber.

And there was no carbon and oxygen in the universe throughout the first generation of stars.

When you evaporate seawater, the first thing to crystallize out is calcium carbonate.

Carbon monoxide is a poisonous substance formed by the incomplete combustion of carbon compounds.

No living things could live without oxygen.

You can't live without oxygen.

My next step's gotta be oxygen.

What's a drug?

There are three basic limitations of scuba diving.

This isn't Volvos this is volcanoes.

Electric pulse generators from the Galactica.

Well, in the context of diving, you get too much, you die also.

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

We need to breathe.

But the real powers of this place come from phytoplankton.

Now, because the fate of water and carbon are tied to soil organic matter, when we damage soils, you give off carbon.

These granules contain three essential plant nutrients.

This was a different record.

Okay, so blood, it carries oxygen to our organs, right? And that's what makes them function.

The air we breathe in, or inspire, has a mixture of gases including nitrogen, carbon dioxide and oxygen, which is the most important for our survival.

Nitrogen, oxygen. Looks like enough CO2 for green leafy things.

It is the spectrum of a planet like Earth, showing a presence of nitrogen dioxide, as a clear signal of life, and oxygen and ozone.

What is it? Parasite in his bloodstream choking him of oxygen.

Meanwhile, the human body consists of 65 oxygen, 18 carbon, 10 hydrogen, and 7 of various other elements including 0.002 of silicon.

We stopped tilling, so that we could prevent greenhouse gasses from going into the air.

It appeared dead.

High oxygen content.

Oxygen! Yes!

Pure oxygen.

Oxygen, yes. Thermal garments...

What's the O2 stat?

Give me an O2 stat.

Iron and oxygen are elements.

Water contains hydrogen and oxygen.

Liquid hydrogen and oxygen.

Trees give off oxygen and absorb carbon dioxide.

Tropical rainforests produce oxygen and consume carbon dioxide.

And then you have two extra pairs of valence electrons in the oxygen.

Nitrogen bonds to oxygen, which in turn....

And after the toe cells have kind of taken out whatever they need.

I'm H2O intolerant.
