Auroras Underfoot.

This is a bowhead whale.

We fly right over them.

Ms. Violet Ford (Inuit Circumpolar Conference)

Auroras are caused by solar activity.

And you'll see that it leads with a shifting star field, and there's an Aurora Borealis in the background, kind of morphing with color.

Especially when you deal with polar coordinates.

The vanishing Arctic sea ice also affects the atmosphere.

I'll bet 3,000 that she'll send him to Sejong Antarctic Research Center. lt BR gt

We were attacked by a polar bear on day two.

A polar bear can swim up to 500 kilometers.

It is not disorienting to see auroras underfoot, he says.

Indeed, more auroras are in the offing.

And the water at the North Pole is minus 1.7.

Its southern counterpart, the aurora australis (or the southern lights), has features that are almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone.

Some companies even seem to celebrate the melting of the polar ice cap, because it will reduce the cost of extracting the oil that lies beneath the Arctic Ocean.

Early evidence for a geomagnetic connection comes from the statistics of auroral observations.

All these islands lie in the cold seas below the Antarctic convergence.

The collection of these interactions is what creates the northern and southern lights.

From this book anyone can learn about the aurora borealis or the Eskimos

A polar bear wouldn't hesitate to attack a huge walrus if it were hungry.

The protons and electrons creating the northern lights depart from the Sun's corona.

These are actually polar dipole bonds with the different sodium or chloride ions.

The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean.

In 1948, the underwater Lomonosov Ridge in the Arctic Ocean was named in his honor.

And you might want to watch my polar coordinate videos, because this essentially touches on that.

We can actually fly into the auroras, says astronaut

Sometimes you feel like you can reach out and touch them.

Projections are that we could lose polar bears they could become extinct in the next 50 to 100 years.

Today, a far greater Arctic tragedy is unfolding the Arctic sea ice cap is melting.

For instance, as the Arctic ice cap melts, less sunlight is reflected.

The first, the Polar Atmospheric Chemistry Programme, is presently active only in the Arctic.

If we were to think of this in polar coordinates, this is t at any given time.

And from out of stage left comes this wild, male polar bear, with a predatory gaze.

And this polar bear stands over the husky, no claws extended, no fangs taking a look.

Projections are that we could lose polar bears, they could become extinct in the next 50 to 100 years.

Longtime sky watchers say it is the greatest show on Earth.

82 to 86 of people with bipolar disorder, have suffered from some form of childhood trauma.

And you'll see that it leads with a shifting star field, and there's an Aurora Borealis in the background, kind of morphing with color. The color of the Aurora Borealis can be controlled using this single bar of color at the bottom, and we'll put it down here to red.

These plants have a distinct trait in their pollen grains of exhibiting three colpi or grooves paralleling the polar axis.

And this polar bear that you see, this 1200 pound male, he's wild and fairly hungry.

These little, fat dumplings, 150 pound bundles of blubber are the mainstay of the polar bear.

Glowing green and red, shimmering hypnotically across the night sky, the aurora borealis is a wonder to behold.

The precise color at any altitude depends on the temperature and density of the local atmosphere.
