North Pole

geography Maturity 7-9 Next article →

The North Pole is the northernmost point on Earth. It is located at the center of the Northern Hemisphere. This point is where the Earth's axis of rotation meets the surface. Scientists call this the Geographic North Pole or the Terrestrial North Pole. It is often called the True North Pole to distinguish it from the Magnetic North Pole.

At this specific location, the rules of geography change. All lines of longitude converge at this single point. Because of this, the North Pole does not have a single longitude. You could define its longitude as any degree value. Furthermore, all directions from the North Pole point south. There are no time zones assigned to this location. This means any time can be used as the local time. Along latitude circles, moving counterclockwise is considered east. Moving clockwise is considered west.

The physical environment of the North Pole is very different from the South Pole. While the South Pole sits on a continent, the North Pole is in the middle of the Arctic Ocean.

The area is covered by constantly shifting sea ice. This ice is often multi-year ice. When ice floes collide, they create large pressure ridges.

The water underneath is very deep. In 1958, the USS Nautilus measured the depth. In 2007, the Russian Mir submersible measured it again. These deep waters make building a permanent station impractical.

Geographers also study how the pole moves. For a long time, people thought the axis was fixed. However, the mathematician Leonhard Euler predicted the axis might wobble. Astronomers eventually noticed a variation of latitude. This is caused by the pole wandering across the Earth's surface. This movement includes a periodic component called the Chandler wobble. This wobble has a period of about 435 days. The exact point where the axis meets the surface is called the instantaneous pole. Because of this wobble, scientists use the International Terrestrial Reference System to maintain accuracy.

Human exploration of the North Pole has a long and difficult history. In the 16th century, many believed an open sea called the Polynya existed there.

Many expeditions tried to find a passage through the ice. Some attempts ended in tragedy. In 1881, the ship Jeannette was crushed by ice, and many crew members were lost. In 1897, a team tried to reach the pole in a hydrogen balloon named Örnen. They crashed and died on the island of Kvitøya.

The first undisputed arrival at the North Pole happened in 1926. An airship called the Norge flew over the area. The expedition leader was Roald Amundsen, and there were 16 men on board. Other famous claims have been controversial. Robert Peary claimed to reach the Pole in 1909 with Matthew Henson and four Inuit men.

However, modern historians have cast doubt on his data. Other claims by Frederick Cook and Richard E. Byrd have also been questioned. The first verified people to reach the Pole on foot were a 24-man Soviet party in 1948. Later, in 1968, a team used snowmobiles to complete a land expedition.

Today, the North Pole is a site for scientific research. Since 1937, the Soviet Union and Russia have used drifting stations. A private Russian base called Barneo also operates there in the spring.

Scientists are particularly interested in Arctic ice shrinkage. Studies in the 2000s predicted the area might become seasonally ice-free. This could happen by the late 21st century.
