North Pole

The North Pole is the northernmost point on Earth, located at 90° N latitude in the middle of the Arctic Ocean, where the Earth’s rotational axis intersects its surface. Unlike the South Pole, which sits on the Antarctic continent, the geographic North Pole lies on the permanent sea ice of the Arctic Ocean, approximately 700 km from the nearest landmass. Since all meridians converge here, every direction from the North Pole is south; the sun rises once a year at the spring equinox and sets once at the autumn equinox, producing six months of continuous daylight followed by six months of polar night.

Overview

The geographic North Pole is defined as the point where the Earth’s axis of rotation meets its surface in the Northern Hemisphere. The Arctic Ocean here reaches depths of approximately 4,000 metres, and the surface is covered by sea ice that drifts constantly, meaning the precise spot must be recalculated on each expedition. The pole sits within the Arctic Circle — the zone where the sun remains above the horizon for at least one full day at the summer solstice and below it for at least one full day at the winter solstice.

History

The quest for the North Pole captivated explorers from the 19th century onward, with expeditions by Robert Peary and Frederick Cook both claiming first arrival in 1909 — claims that remain disputed by polar historians. The first undisputed over-flight was made by Roald Amundsen aboard the airship Norge in May 1926. The first Soviet landing on the ice occurred in 1948; the first confirmed surface expedition to reach the pole and return was led by Ralph Plaisted in 1968–69. The pole has since been reached by nuclear-powered icebreakers, aircraft, ski expeditions, and even submerged submarines.

What you see

At the North Pole, the traveller finds a flat expanse of sea ice — pressure ridges, open leads of dark water, and wind-sculpted snowfields stretching in every direction under an enormous sky. In summer, the sun traces low circles above the horizon without setting; temperatures range from around −10°C in June to −40°C or lower in January. Wildlife in the central Arctic Ocean is sparse but may include polar bears traversing the ice, Arctic fox, and seabirds far from shore. The ice itself is in constant motion: ice camps must be established with awareness that the surface drifts several kilometres per day.

Cultural significance

The North Pole has been one of the great symbolic objectives of modern exploration, representing the limits of human endurance and the drive to map the unknown. As a concept it figures prominently in navigation, cartography, and mythology — from Santa Claus’s legendary home to the focus of geopolitical contest over Arctic sovereignty and resources in the 21st century. The rapid loss of summer sea ice due to climate change has transformed the Arctic from an impenetrable wilderness into a contested maritime passage, making the North Pole a barometer of planetary environmental change.

Practical information

Access: Accessible by nuclear icebreaker from Murmansk, Russia (approx. 4–5 days voyage); charter ski expeditions from Longyearbyen (Svalbard); fly-in camp expeditions (April–May window)
Season: Expeditions typically operate April–May (stable ice, polar day); summer cruises June–August
Operators: Russian nuclear icebreaker cruises (Rosatom/Atomflot); specialist Arctic expedition companies — check current providers for schedules and costs

Getting there

The most accessible route for civilians is an icebreaker voyage departing from Murmansk in northern Russia. Expedition ski journeys to the pole depart from the Russian drifting ice station or from Ward Hunt Island in Canada after a charter flight to Resolute Bay. Helicopter-supported fly-in programmes operate from Longyearbyen (Svalbard) during the April–May window when the ice is stable enough for a camp. All North Pole expeditions require specialist polar expedition outfitters and significant advance planning.

Sources & resources

The term North Pole generally indicates the most northerly (or northerly) point of any celestial body (eg a planet or a star) and by convention is used as the primary reference system with respect to the south pole.



When we say: show me the North, or where exactly is the North Pole, exactly where on the Earth are we turning?
&nbsp;

The question is not strange because in the north, and therefore in the north poles, there is more than one. Limiting ourselves to the most common, we can find at least five: the geographic North Pole, also called the terrestrial North Pole or true north, the magnetic North Pole, the geomagnetic North Pole, the North Pole of inaccessibility and the North Celestial Pole.



Referring to the Earth, the term can indicate different geographical points located on the earth&#39;s surface, most of which are located in the Arctic Ocean, and is also used to refer generically to that region of the world called the Arctic or in some cases to the territory included within the Arctic Circle.



With &quot;North Pole&quot; we can also mean the positive magnetic pole (P) of a magnet, the magnetic one varies over the years.



The position of the four poles in 2003:
1: Geographic North Pole - Terrestrial
2: Magnetic North Pole
3: Geomagnetic North Pole
4: North Pole of Inaccessibility
5: North Celestial Pole




The north pole of inaccessibility.

Unlike the others, it is not characterized by physical peculiarities, but, like the other poles of inaccessibility, it has the characteristic of being complex to reach.

In this case the indicates the point of the Arctic Ocean furthest from each coastline and it is the one inserted in this map that coincides with the Geographic one.

It is located about 1 100 km from the nearest coast at the following geographical coordinates: 84 &deg; 03&prime;N - 174 &deg; 51&prime;W.



The first flyby of this particular geographical place was made in 1927 by Hubert Wilkins; later, in 1958 it was first reached by a Soviet icebreaker.




The legend

Many legends related to the figure of Santa Claus predict that his house is located in the North Pole.



Here he is helped by his elves and receives letters from the children with requests for gifts that he then builds


History

Until the 19th century it was believed that the geographic north pole was a fixed point, however this belief was disproved thanks to very accurate measurements based on the observation of the stars and studies carried out by the American astronomer Seth Carlo Chandler (1846-1913) .



Chandler in 1891 discovered that the geographic north pole, seen from above, is not motionless but moves, describing an approximate circle, around a point called the &quot;mean pole of rotation&quot;, this motion was later named in his honor the Chandler oscillation.



The Chandler oscillation has a period of about 435 days and the imperfect circle it describes around the mean rotation pole, which has an average amplitude of about 6 meters), is due to the irregular shape of the Earth and the imperfect alignment of the &#39;axis of rotation of the earth with the axis of inertia of the earth.



This misalignment causes the Earth to oscillate slightly over rotating on its axis, similar to the motion of a slightly unbalanced top. There are several theories on the causes of this misalignment, initially it was believed that they were to be found in earthquakes but recent studies carried out by Richard Gross of the Jet Propulsion Laboratory would have shown that the main causes are attributable to variations in sea water pressure on the seabed. due to changes in the percentage of dissolved salts in the water.



It would be desirable that the system of terrestrial coordinates (latitude, longitude and orography) refers to fixed morphological points, however due to natural phenomena such as: continental drift, volcanism, erosion and other factors, there are no systems in which all the characteristics geographical areas are fixed.



To overcome the problems that the lack of fixed reference points can generate, the International Earth Rotation and Reference Systems Service (IERS) and the International Astronomical Union (UAI) have developed a mathematical model called the International Earth Reference System (ITRS). The north pole of this model defines the geographic north pole and does not coincide with the earth&#39;s rotation axis.


EXPLORATIONS:


	On April 21, 1908, Frederick Cook along with the 2 Inuit Etukishook and Ahwelah were absolutely at the closest point to the geographic North Pole. They had succeeded in the enterprise of arriving at the &quot;Big Nail&quot;. They remained on site for two days during which Cook made several measurements to confirm the latitude. Before returning home he put a note in a brass tube and hid it in a crevice in the ice.
	April 6, 1909 - second expedition to reach the geographic north pole. The enterprise was directed by the American Robert Edwin Peary; other members of the expedition were his assistant Matthew Henson and four Inuit called Ootah, Seegloo, Egingway, and Ooqueah. The analyzes carried out on some of Peary&#39;s annotations found in 1996 have led historians to believe that Peary in believing that he reached the geographic North Pole has actually only passed very close to it; to be precise, he would have arrived about 20 nautical miles (about 40 km) from the geographic north pole.





	May 12, 1926 - first overflight of the geographic north pole aboard the Norge airship, piloted and designed by the Italian Umberto Nobile. Among others were: the Norwegian explorer Roald Amundsen and the financier of the venture, the American Lincoln Ellsworth. The flight began from the Norwegian archipelago of Svalbard and after a crossing of over 5300 km of uninterrupted flight ended with a landing in Alaska.





	May 24, 1928 - Umberto Nobile on board the airship Italia manages to reach and fly over the geographic north pole for the second time. During the return trip, however, Italy crashes on the polar ice pack.



Despite this accident, which had global significance, thanks to the start of the first international relief expedition to be operating in the north pole area, Nobile was saved.




	April 23, 1948 - The Soviet Aleksandr Kuznetsov, together with 23 companions, landed near the pole, and then continued on foot to the geographic north pole, thus becoming the first human being to succeed in the feat.




This version of events is mainly supported by the Scott Polar Research Institute of the University of Cambridge, while the Antarctica.org institute believes that an expedition made up of seven Soviets, in turn landed in the north, was the first to reach the geographic North Pole on foot. vicinity with three Lisunov Li-2. According to other sources, the Soviet Pavel Gordiyenko was the first to reach the geographic north pole on April 23, 1948, along with three or five other men.


	May 3, 1952 - United States Air Force Lieutenant Colonel Joseph O. Fletcher, Lieutenant William P. Benedict and scientist Albert P. Crary, aboard a suitably modified C-47 aircraft, made the first landing on the North Pole geographical. The three members of this enterprise are considered by some sources to be the first humans to have set foot with relative exactness at the geographic North Pole.
	In 1955 Louise Boyd was the first woman to overlook the point.
	August 3, 1958 - The United States Navy&#39;s first nuclear-powered submarine USS Nautilus (SSN-571) crosses (submerged) the geographic North Pole for the first time.
	March 17, 1959 - the USS Skate submarine (SSN-578) first emerges on the geographic north pole becoming the first naval vessel to have reached it.
	April 19, 1968 - Ralph Plaisted manages to reach the polo with a snowmobile. This is the first confirmed conquest of the pole with surface vehicles.





	August 17, 1977 - Soviet nuclear icebreaker NS Arktika reaches pole. It is the first vessel traveling above the surface of the water to have reached the North Pole.
