It's not static.

This is the foundation of the whole food chain in the Arctic, right here.

And we drilled in the Ross Sea.

They'll think about a big ass ship in the North Pole, breaking ice. Says you.

But it's the North Pole.

This was a bear I sat with for a while on the shores.

By 14,000 years ago, the Ice Age was winding down.

The weight of the ice is such that the entire continent sags below sea level, beneath its weight.

Thank you very much. I appreciate it.

Because it's partly floating, you can imagine, is sea level rises a little bit, the ice lifts off the bed, and then it can break off and float north.

And this vent fluid is about 600 or 700 degrees F.

The continents move apart. They come back together.

Second, remember that the Arctic is really a frozen ocean.

We scouted the ice moon. Found an entire subsurface ocean.

The ocean.

Icebergs had been grounded on the beach.

One of the magical things about this journey, however, is that because I'm walking over the sea, over this floating, drifting, shifting crust of ice that's floating on top of the Arctic Ocean is it's an environment that's in a constant state of flux.

Mountains and seas will still be there.

I'll end up with saying one thing.

These ringed seals also live out their entire life cycle associated and connected to sea ice.

There isn't even a pole at the Pole.

The pirates sailed the seven seas.

Unlike sea ice or pack ice, which form when the ocean freezes, glaciers are made of fresh water.

These curves for global temperature, atmospheric CO2 and sea level were derived from ocean cores and Antarctic ice cores, from ocean sediments and snowflakes that piled up year after year over 800,000 years forming a two mile thick ice sheet.

I went to Hokkaido to see the floating ice.

This glacier has doubled its flow speed in the past 15 years.

This is quite good.

The one glacier up in Greenland that puts more ice into the global ocean than all the other glaciers in the northern hemisphere combined is the Ilulissat Glacier.

How about some X Prizes for ocean exploration?

He sailed the Seven Seas.

There perhaps is the CO2 from the person sitting next door to you.

Maybe you have thalassophobia. This is fear of the ocean.

Sea Theme

Curse the sea!

People call the sea the Mediterranean.

That sea is called the Mediterranean Sea.

Next time you drink a glass of water, you're drinking the ocean.

All hail Neptune, and those who party on his mighty waves.

Pull up the Japanese sea border.

The equalization of the oceanic

This, of course, is the Arctic Ocean, the floating ice cap.

A number of years ago, he tried to ski all the way to the North Pole.

It makes it seem almost as if we're looking through the ice to the ocean beneath.
