Northernmost Point Of Land
The northernmost point of land on Earth is a contentious issue due to variation of definition. How permanent some of the contenders are makes hard determination difficult, but sets an important threshold. Problematic issues include ice sheets, water movements and inundation, storm activity that may build, shift, or destroy banks of moraine material, and observational difficulties due to remoteness. The following table sets out the main contenders for this title. Currently, Kaffeklubben Island is the northernmost, undisputed candidate among the land areas considered permanent that remain above water.

Kaffeklubben Island Aerial Photo
Kaffeklubben Island or Coffee Club Island ( da, Kaffeklubben Ø; kl, Inuit Qeqertaat) is an uninhabited island lying off the northern tip of Greenland. It contains the northernmost undisputed point of land on Earth. Discovery The first recorded sighting of Kaffeklubben Island was made by American explorer Robert Peary in 1900; however, the island was not visited until 1921. When the Danish explorer Lauge Koch set foot on the island, it received its name after the coffee club in the University of Copenhagen Geological Museum. In 1969, a Canadian team calculated that its northernmost tip is farther north than Cape Morris Jesup, the northernmost point of mainland Greenland, thus claiming its record as the most northerly point on land. Since its record as the northernmost point of land was established, several gravel banks have been discovered in the sea to the north of the island, such as Oodaaq, 83-42, and ATOW1996; however, there is debate as to whether such gravel banks s ...

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Sheet
In glaciology, an ice sheet, also known as a continental glacier, is a mass of glacial ice that covers surrounding terrain and is greater than . The only current ice sheets are in Antarctica and Greenland; during the Last Glacial Period at Last Glacial Maximum, the Laurentide Ice Sheet covered much of North America, the Weichselian ice sheet covered Northern Europe and the Patagonian Ice Sheet covered southern South America. Ice sheets are bigger than ice shelves or alpine glaciers. Masses of ice covering less than 50,000 km2 are termed an ice cap. An ice cap will typically feed a series of glaciers around its periphery. Although the surface is cold, the base of an ice sheet is generally warmer due to geothermal heat. In places, melting occurs and the melt-water lubricates the ice sheet so that it flows more rapidly. This process produces fast-flowing channels in the ice sheet — these are ice streams. The present-day polar ice sheets are relatively young in geol ...

North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though some perhaps semi-permanent gravel banks lie slightly clos ...

83-42
83-42 is a rocky islet in the Arctic Ocean which may be the northernmost permanent point of land on Earth. It is also sometimes referred to as Eklipse 0, or Schmitt’s Island, after its discoverer, Dennis Schmitt. It measures and in height, and lies from the North Pole. When it was discovered in 1998, lichens were found growing on it, suggesting it was not one of the temporary gravel bars commonly found in that region. The island was discovered on 6 July 2003 by an American expedition led by Dennis Schmitt and Frank Landsberger. The expedition members gave it the unofficial name 83-42, reflecting its latitude of 83 degrees 42 minutes north. To be recognized as land area it is required that the area permanently rise out of the water, even at high tide. Given its very small size, it is doubtful whether 83-42 has this property. According to its discoverer, 83-42 is composed of rocks and boulders, a relatively resistant material, and is not just a fleeting sand and gravel bank. ...

Dennis Schmitt
Dennis Schmitt (born May 23, 1946) is a veteran explorer, adventurer and composer. Early life Schmitt grew up in Berkeley, California, the son of mixed German and American parentage. His father was a plumber. Displaying early aptitude with languages, music and mathematics, Schmitt graduated from Berkeley High School in 1963, and went on to study linguistics at UC Berkeley with Noam Chomsky in his late teens. Chomsky recruited Schmitt, aged 19, to travel to Alaska's Brooks Range and attempt to learn the Nunamiut dialect. Career Schmitt lived for four years at an Alaskan Eskimo village named Anaktuvuk Pass before leading expeditions, including the Sierra Club. In 2003, Schmitt discovered one of the candidates of being the northernmost land in the world. Deciding that Greenland should name its own islands, he simply called it "83-42", a name that has remained. Two years later, in 2005, Schmitt discovered a new island formed by the retreat of an ice shelf in East Greenland. Uuna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meter
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redefiniti ...

ATOW1996
ATOW1996 is one of the northernmost documented points of land on Earth. It is a small island about long and one metre high, located several miles north of Cape Morris Jesup in northern Greenland at . It was discovered by and named after the (American) Top of the World Expedition of 1996. A non-permanent island even farther north—at —was noted in a Twin Otter flyover by the 2001 Return to the Top of the World Expedition (RTOW2001). This expedition also confirmed the continuing existence of ATOW1996. For years, Kaffeklubben Island, discovered in 1921 by Danish explorer Lauge Koch at , was thought to be the northernmost point of land. In 1977, however, a Danish expedition discovered Oodaaq Island further north at . The American Top of the World Expedition of 1996 was able to locate what they thought was Oodaaq Island, but doubts remain because of the inconsistency between the island they reached, "ATOW1996," and those recorded by the original discoverers of Oodaaq.

Stray Dog West
Stray Dog West is an island in Greenland. It is a candidate for the northernmost island on Earth. History Stray Dog West was discovered during a 2007 expedition led by Dennis Schmitt. The island is four meters above sea level, making it likely that rising oceans will eventually permanently submerge the island. The island was made of sediment with gravel, mud and boulders. It was estimated in 2007 that the island had a landmass of 100 x 60m. Territorial disputes In 2007, Denmark sent an icebreaker to the surrounding area in order to find data to attempt an extension of its maritime territory. Russia disagreed with Denmark's proposal and claimed that the ridge underneath the ocean came from Russia, making the Stray Dog West and other disputed islands Russian territory. It is also disputed over whether Stray Dog West counts as an island, as it is submerged at high tide.

Qeqertaq Avannarleq
Qeqertaq Avannarleq () is an unofficial name of what was thought to be a previously uncharted island in the Arctic Ocean, discovered in August 2021. It is within the Arctic Circle, off of the northern tip of Greenland, and consists primarily of seabed mud and moraine, an accumulation of unconsolidated debris left behind by glaciers. One theory as to its creation was that it was formed relatively recently, during a violent storm. In September 2022, Danish researcher René Forsberg, head of geodynamics at the National Space Institute in Denmark, announced that further research had shown Qeqertaq Avannarleq "unequivocally" is not an island, but the top of a grounded iceberg, covered by a layer of soil, pebbles and mud, likely deposited by from glaciers in the area. This gravel bank has been among the candidates to be recognized as the northernmost point of land. An undisputed candidate, Kaffeklubben Island is classified as permanent, being discovered in 1900 A.D., and being 750 metr ...

Oodaaq
Oodaaq or Oodap Qeqertaa is a bank of gravel and silt northeast of Greenland that has been considered by some to be the northernmost point of land on Earth, though a number of other places have also been given that title since its discovery. It may have been created by the impact of an iceberg in a shallow sea. However, the area of ice in which it appears does not move from year to year. If it was created by an iceberg, then it must have happened long ago. Location Oodaaq lies at 83° 40′ North and 30° 40′ West, only south of the North Pole and north of Kaffeklubben Island, lying near the northeast tip of Greenland. When discovered it measured a mere . History It was discovered in 1978 when a Danish survey team led by Uffe Petersen landed a helicopter on Kaffeklubben Island to confirm that it did indeed lie further north than the tip of Greenland. Having confirmed the fact, a member of the team noticed a dark spot northeast of Kaffeklubben Island. The survey team land ...
