This productivity sinks and decomposes at mid ocean depths, consuming dissolved oxygen and, when combined with sluggish water circulation, leads to the development of massive areas of mid water oxygen minima.

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

This atmosphere, this oxygen... iùs burning me up.

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.

I've drawn the oxygen in blue, and then the hydrogens that are bonded with that oxygen I've done in white.

Oxygen not needed.

So, in general, if you think about solubility of a solute in water or especially if you think of a solid solute, which is sodium chloride into a liquid solvent, then the higher the temperature while you're in the liquid state, the more of the solid you're going to be able to get into the liquid, or you're going to raise solubility.

So here, oxygen hogs.

And they're going to oxygen.

Breathe that oxygen! Breathe!

So solute particles make you have a lower boiling point.

Because of the movement I was wasting oxygen.

And it was time for us to put oxygen in.

A lack of oxygen in the water.

Because of the movement, I was wasting oxygen.

We had lost seven tons of oxygen.

So this is the reduction of oxygen to water.

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

The oxygen tanks didn't quite work right.

The whole point is to get the oxygen.

I'm breathing in a million billion billion atoms of oxygen.

Leo, you have to breathe that oxygen.

let's have another one that's over here, some relatively

Now, we all know the song

There's a built in oxygen concentrator down there.

Now you've heard me mention oxygen a few times at this point.

And by gaining hydrogens, oxygen is being reduced.

The technology for oxygen delivery is not new.

It requires oxygen.

And this happened in the absence of oxygen.

It's going away from the heart to get the oxygen.

Most of the oxygen in the atmosphere is generated by the sea.

The constant, known as the Henry's law constant, depends on the solute, the solvent and the temperature.

If you give mice hydrogen sulfide, you can lower their demand for oxygen, and you can put them into oxygen concentrations that are as low as 5,000 feet above the top of Mt.

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.

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

Oxygen, hydrogen and zinc have their own signature.

It can occur with oxygen or without it.

like in a game of musical chairs where oxygen might bind?

The production rate of a particular isotope depends on the energy of the oxygen beam.

And maybe that other oxygen is bonded to this hydrogen.

Oxygen concentrators are very old technology.

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

So this is when you don't have oxygen.
