Polar Region Wonders of the World

Natural Wonders of the Polar Regions

 

Visit the 15 natural world wonders of the Polar Regions, from the Greenland Icecap, to the Dry Valleys.

Antarctica is fifth in size among the world's continents. Its landmass is almost wholly covered by a vast ice sheet.
[1]
The continental ice sheet contains approximately 7 million cubic miles (29 million cubic km) of ice
Many parts of the Ross and Weddell seas are covered by ice shelves, or ice sheets floating on the sea. These shelves—the Ross Ice Shelf and the Filchner-Ronne Ice Shelf—together with other shelves around the continental margins, constitute about 10 percent of the area of Antarctic ice.

 

 

The Arctic Circle is a parallel, or line of latitude around the Earth, at approximately 66°30' N.
     
Aurora Borealis at the Arctic Circle Arctic Circle[2]
Because of the Earth's inclination of about 23 1/2° to the vertical, it marks the southern limit of the area within which, for one day or more each year, the Sun does not set (about June 21) or rise (about December 21).

The length of continuous day or night increases northward from one day on the Arctic Circle to six months at the North Pole.[3]


This is a time lapse of a whole day that takes place about 70 miles below the arctic circle. It is the sun rising in the South and setting in the west horizontally across the sky.

Each year the sun is below the horizon for 4 months in the middle of winter, and above the horizon for 4 months in summer. During the couple of months in between we have more-or-less normal days.
Includes shots of auroras and the very rare polar stratospheric nacreous clouds, which form when ozone depleting gases crystallize in the upper atmosphere in the intense cold.
Summer population is about 1200 people, winter about 200.
