Climate change, ocean acidification, dissolved oxygen, carbon cycle, coastal upwelling, fishing dynamics the full spectrum of earth science and ocean science simultaneously in the same volume.

Oxygen from the air dissolves in water.

You see, hydrofluoric acid won't eat through plastic.

This top light is I'm sorry if I'm making you seasick this top light is actually a water quality display that shifts from red, when the dissolved oxygen is low, to a blue green, when its dissolved oxygen is high.

And we know, of course, that since it's a strong acid it disassociates completely.

Demerol is a morphine sulfate. It is soluble in water.

Dissolving in strong acid.

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.

Now, there was no carbon and oxygen in the universe at the Big Bang.

Any decent acid's gonna eat right through this.

My next step's gotta be oxygen.

Now that's an incredible phenomena, because it's a star that sits there.

What's a drug?

There are three basic limitations of scuba diving.

This isn't Volvos this is volcanoes.

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

We need to breathe.

These granules contain three essential plant nutrients.

This was a different record.

Now before that mixture hits the patient's lungs, it's going to pass by here you can't see it, but there's an oxygen sensor here that's going to read out on this screen the percentage of oxygen being delivered.

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.

You need oxygen to breathe.

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

Oxygen and hydrogen make water.

Computes the melting temperature for a nucleic acid duplex.

It's here, the brain.

(Laughter) (Applause)

How you doin' on air?
