North Pole
Northernmost point on Earth, located in the Arctic Ocean.
Last updated
The North Pole, also referred to as the Geographic or Terrestrial North Pole, is the northernmost point on Earth, located where the planet’s axis of rotation intersects its surface in the Northern Hemisphere. This point defines a latitude of 90° North, and because all lines of longitude converge here, its longitude is undefined. At the Pole, every direction points south, and no official time zone exists, allowing any time to be used locally. The nearest land is typically considered Kaffeklubben Island, off Greenland’s northern coast, while the closest permanently inhabited settlement is Alert, Canada, on Ellesmere Island.
Unlike the South Pole, which rests on a continental landmass, the North Pole lies in the Arctic Ocean, covered by constantly shifting sea ice. The ocean depth at this location has been measured at different times, with the Russian submersible Mir recording one value in 2007 and the USS Nautilus another in 1958.
This ice cover makes a permanent station impractical, though the Soviet Union and later Russia have operated manned drifting stations since 1937, some passing near or over the Pole. Since 2002, a private Russian base called Barneo has been established seasonally for a few weeks each early spring. Studies in the 2000s predicted that Arctic ice shrinkage could lead to seasonally ice-free conditions at the Pole, with timelines ranging from 2016 to later centuries.
The Earth’s rotational axis is not perfectly fixed; a slight wobble, predicted by Leonhard Euler in the 18th century, causes the Pole to wander a few meters over time. This movement includes a periodic component of about 435 days, known as the Chandler wobble. For precise definitions, the International Terrestrial Reference System, maintained by international scientific bodies, provides a fixed coordinate framework.
Attempts to reach the North Pole began in the late 19th century, with the “Farthest North” record repeatedly broken. The first undisputed arrival was by the airship Norge in 1926, carrying 16 men including Roald Amundsen. Earlier claims by Frederick Cook, Robert Peary, and Richard Byrd were later questioned. The first verified individuals to reach the Pole on foot were a 24-person Soviet team in 1948, part of the Sever-2 expedition, who flew nearby before trekking the final distance.
Lore & Background
The North Pole, also known as the Geographic North Pole, is the northernmost point on Earth, located in the middle of the Arctic Ocean. Unlike the South Pole, which sits on a continental landmass, the North Pole lies amid waters almost permanently covered by constantly shifting sea ice. This ice cover makes it impractical to build a permanent station at the Pole itself. The sea depth at this location has been measured, and the nearest land is typically considered Kaffeklubben Island, off Greenland’s northern coast, though some semi-permanent gravel banks may be slightly closer.
The nearest permanently inhabited place is Alert on Ellesmere Island, Canada. Because all lines of longitude converge at the Pole, its longitude can be defined as any degree value, and no time zone has been assigned, allowing any time to be used as local time. The Earth’s axis of rotation does not remain perfectly fixed; it wobbles slightly over time, a phenomenon predicted by Leonhard Euler and later identified as the Chandler wobble, causing the instantaneous pole to wander by a few meters.
Attempts to reach the North Pole began in the late 19th century, with the first undisputed expedition being the airship Norge in 1926, led by Roald Amundsen. Earlier claims by Frederick Cook, Robert Peary, and Richard E. Byrd were later cast into doubt. The first verified individuals to reach the Pole on foot were a Soviet party in 1948, and the first complete land expedition using snowmobiles arrived in 1968. Studies in the 2000s predicted that the North Pole may become seasonally ice-free due to Arctic ice shrinkage.
Reader's Guide
The North Pole is the northernmost point on Earth, defined by the intersection of the planet’s axis of rotation with its surface, and lies antipodal to the South Pole. Unlike the South Pole, which rests on a continental landmass, the North Pole is situated in the middle of the Arctic Ocean, amid waters almost permanently covered by shifting sea ice. The sea depth at this location has been measured, and the constantly moving ice makes constructing a permanent station impractical. However, since 1937, the Soviet Union and later Russia have operated a series of manned drifting stations on an annual basis, some of which have passed over or very close to the Pole.
Since 2002, a private Russian base called Barneo has also been established near the Pole for a few weeks each early spring. The nearest land is Kaffeklubben Island off Greenland, while the nearest permanently inhabited place is Alert on Ellesmere Island, Canada. The North Pole’s position is not entirely fixed; it experiences a slight periodic wobble of a few meters, known as the Chandler wobble, which was predicted by Leonhard Euler in the 18th century and later confirmed.
Historically, attempts to reach the Pole began in the late 19th century, with the first undisputed expedition being the airship Norge in 1926, led by Roald Amundsen. Earlier claims by Frederick Cook, Robert Peary, and Richard Byrd were later cast into doubt. The first verified individuals to reach the Pole on foot were a Soviet party in 1948, and the first complete land expedition using snowmobiles occurred in 1968. Studies in the 2000s predicted that the North Pole may become seasonally ice-free due to Arctic ice shrinkage, with timescales varying widely.
Frequently Asked Questions
What is the Geographic North Pole?
It is the exact point in the Northern Hemisphere where Earth's rotational axis intersects the surface, marking geodetic latitude 90° North. This makes it the absolute northernmost spot on the planet.
Where is the North Pole physically located?
It sits in the middle of the Arctic Ocean, surrounded by constantly shifting sea ice rather than solid land. Because of this, its precise position drifts slightly over time as the ice moves.
How does the North Pole relate to the South Pole?
The two points are antipodal, meaning they sit directly opposite each other on a straight line through Earth's center. Together they define the axis around which the planet spins.
