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 ...

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 ...

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.

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. ...

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.

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
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 ...

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] |
Cape Morris Jesup
Cape Morris Jesup ( da, Kap Morris Jesup) is a headland in Peary Land, Greenland. Geography Cape Morris Jesup is the northernmost point of mainland Greenland. It is from the North Pole#Geographic North Pole, geographic North Pole. It is located in Johannes V. Jensen Land, about east of the mouth of Sands Fjord and west of Constable Bay. The cape marks the limit between the Lincoln Sea to the west and the Wandel Sea to the east. About southeast of the cape there is a river forming a small delta that flows from the Mary Peary Peaks, part of the Roosevelt Range to the south. History Robert Peary reached the cape on 13 May 1900, believing it to be the extreme points of Earth, northernmost point of land in the world, although it was later found to lie slightly to the south of the northernmost tip of Kaffeklubben Island. The cape is named after American philanthropist Morris Ketchum Jesup, president of the Peary Arctic Club, who helped finance Peary's expeditions. Plants Specimens ...

Drift Ice
Drift ice, also called brash ice, is sea ice that is not attached to the shoreline or any other fixed object (shoals, grounded icebergs, etc.).Leppäranta, M. 2011. The Drift of Sea Ice. Berlin: Springer-Verlag. Unlike fast ice, which is "fastened" to a fixed object, drift ice is carried along by winds and sea currents, hence its name. When drift ice is driven together into a large single mass (>70% coverage), it is called pack ice. Wind and currents can pile up that ice to form ridges up to tens of metres in thickness. These represent a challenge for icebreakers and offshore structures operating in cold oceans and seas. Drift ice consists of ice floes, individual pieces of sea ice or more across. Floes are classified according to size: ''small'' – to ; ''medium'' – to ; ''big'' – to ; ''vast'' – to ; and ''giant'' – more than . Drift ice affects: * Security of navigation * Climatic impact (see Polar ice packs) * Geological impact * Biosphere influence (see Ecol ...

Sea Ice
Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. General features and dynamics Sea ice does not simply grow and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
