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] |
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 ...

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.

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 ...

Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately and is known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is t ...

San Francisco Chronicle
The ''San Francisco Chronicle'' is a newspaper serving primarily the San Francisco Bay Area of Northern California. It was founded in 1865 as ''The Daily Dramatic Chronicle'' by teenage brothers Charles de Young and M. H. de Young, Michael H. de Young. The paper is owned by the Hearst Corporation, which bought it from the de Young family in 2000. It is the only major daily paper covering the city and county of San Francisco. The paper benefited from the growth of San Francisco and had the largest newspaper circulation on the West Coast of the United States by 1880. Like other newspapers, it experienced a rapid fall in circulation in the early 21st century and was ranked 18th nationally by circulation in the first quarter of 2021. In 1994, the newspaper launched the SFGATE website, with a soft launch in March and official launch November 3, 1994, including both content from the newspaper and other sources. "The Gate" as it was known at launch was the first large market newspaper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Gravel Bar
A bar in a river is an elevated region of sediment (such as sand or gravel) that has been deposited by the flow. Types of bars include mid-channel bars (also called braid bars and common in braided rivers), point bars (common in meandering rivers), and mouth bars (common in river deltas). The locations of bars are determined by the geometry of the river and the flow through it. Bars reflect sediment supply conditions, and can show where sediment supply rate is greater than the transport capacity. A mid-channel bar, is also often referred to as a braid bar because they are often found in braided river channels. Braided river channels are broad and shallow and found in areas where sediment is easily eroded like at a glacial outwash, or at a mountain front with high sediment loads. These types of river systems are associated with high slope, sediment supply, stream power, shear stress, and bed load transport rates. Braided rivers have complex and unpredictable channel patterns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
