Dundas, Greenland
Pituffik is a former settlement in northern Greenland, located at the eastern end of Bylot Sound by a tombolo known as ''Uummannaq'', near the current site of the American Thule Air Base. The former inhabitants were relocated to the present-day town of Qaanaaq. The relocation and the fallout from the 1968 Thule Air Base B-52 crash in the vicinity are a contentious issue in Greenland's relations with Denmark and the United States. Exploration Pituffik was a hunting village of the Greenlandic Inuit. The Qaanaaq region of northern Greenland in which it is located was inhabited for several thousand years, first settled 4,500 years ago by the Paleo-Eskimo peoples migrating from the Canadian Arctic. The area was explored by Commander James Saunders of the Royal Navy while wintering on HMS ''North Star'' in 1849-50 after being trapped by the ice in the sound.

Tombolo
A tombolo is a sandy or shingle isthmus. A tombolo, from the Italian ', meaning 'pillow' or 'cushion', and sometimes translated incorrectly as ''ayre'' (an ayre is a shingle beach of any kind), is a deposition landform by which an island becomes attached to the mainland by a narrow piece of land such as a spit or bar. Once attached, the island is then known as a tied island. Several islands tied together by bars which rise above the water level are called a tombolo cluster. Two or more tombolos may form an enclosure (called a lagoon) that can eventually fill with sediment. Formation The shoreline moves toward the island (or detached breakwater) due to accretion of sand in the lee of the island, where wave energy and longshore drift are reduced and therefore deposition of sand occurs. Wave diffraction and refraction True tombolos are formed by wave refraction and diffraction. As waves near an island, they are slowed by the shallow water surrounding it. These waves th ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lonely Planet
Lonely Planet is a travel guide book publisher. Founded in Australia in 1973, the company has printed over 150 million books. History Early years Lonely Planet was founded by married couple Maureen and Tony Wheeler. In 1972, they embarked on an overland trip through Europe and Asia to Australia, following the route of the Oxford and Cambridge Far Eastern Expedition. The company name originates from the misheard "lovely planet" in a song written by Matthew Moore. Lonely Planet's first book, ''Across Asia on the Cheap'', had 94 pages; it was written by the couple in their home. The original 1973 print run consisted of stapled booklets with pale blue cardboard covers. Tony returned to Asia to write ''Across Asia on the Cheap: A Complete Guide to Making the Overland Trip'', published in 1975. Expansion The Lonely Planet guide book series initially expanded to cover other countries in Asia, with the India guide book in 1981, and expanded to rest of the world later on. G ...

Plutonium
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthetically produced and isolated in late 1940 and early 1941, by a deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 ( half-life 2.1 days) was synthesized, which subsequently beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Since ...

Radioactive Decay
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay ( ), beta decay ( ), and gamma decay ( ), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetism and nuclear force. A fourth type of common decay is electron capture, in which an unstable nucleus captures an inner electron from one of the electron shells. The loss of that electron from the shell results in a cascade of electrons dropping down to that lower shell resulting in emission of discrete X-rays from the transitions. A common example is iodine-125 commonly used in medical settings. Radioactive decay is a stochastic (i.e. random) proce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Greenland
Air Greenland A/S (formerly named Grønlandsfly), also known as Greenlandair, is the flag carrier airline of Greenland, owned by the Greenlandic Government.

Melville Bay
Melville Bay ( kl, Qimusseriarsuaq; da, Melville Bugt), is a large bay off the coast of northwestern Greenland. Located to the north of the Upernavik Archipelago, it opens to the south-west into Baffin Bay. Its Kalaallisut name, ''Qimusseriarsuaq'', means "the great dog sledding place". The bay was named after Robert Dundas, 2nd Viscount Melville, (1771 - 1851) head of the Admiralty. Geography Melville Bay is delimited by Cape York in the northeast and Wilcox Head, the western promontory on Kiatassuaq Island in the south.''Upernavik Avannarleq'', Saga Map, Tage Schjøtt, 1992 Some islands of the Upernavik Archipelago are in the Melville Bay area, such as Kiatassuaq Island, Kullorsuaq Island, Saarlia Island and Saqqarlersuaq Island. Melville Bay is free of fast ice between mid August and the end of September on average. Navigation is dangerous as there are numerous icebergs in the bay throughout the year.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute,'' p. 8 ...

Savissivik
Savissivik (West Greenlandic; old spelling: ''Savigsivik'') or Havighivik (Inuktun) is a settlement in the Avannaata municipality in northern Greenland. Located on Meteorite Island, off the northern shores of Melville Bay, the settlement had 55 inhabitants in 2020. History In the Greenlandic language, the name ''Savissivik'' means "Place of Meteoric Iron" or "Knives", alluding to the numerous meteorite fragments that have been found in the area dating to about 10,000 years ago. The Cape York meteorite is estimated to have weighed 100 tonnes before it exploded. The iron from the meteorite is believed to have attracted migrating Inuit from Arctic Canada. Transport Air Greenland operates settlement flights to Qaanaaq Airport via Thule Air Base Thule Air Base (pronounced or , kl, Qaanaaq Mitarfik, da, Thule Lufthavn), or Thule Air Base/Pituffik Airport , is the United States Space Force's northernmost base, and the northernmost installation of the U.S. Armed Forces, locat ...

Nuuk
Nuuk (; da, Nuuk, formerly ) is the capital and largest city of Greenland, a constituent country of the Kingdom of Denmark. Nuuk is the seat of government and the country's largest cultural and economic centre. The major cities from other countries closest to the capital are Iqaluit and St. John's in Canada and Reykjavík in Iceland. Nuuk contains a third of Greenland's population and its tallest building. Nuuk is also the seat of government for the Sermersooq municipality. In January 2021, it had a population of 18,800. The city was founded in 1728 by the Dano-Norwegian missionary Hans Egede when he relocated from the earlier Hope Colony () where he arrived in 1721. The governor Claus Paarss was part of the relocation. The new colony was placed at the Inuit settlement of Nûk and was named ''Godthaab'' ("Good Hope"). "Nuuk" is the Greenlandic word for "cape" ( da, næs) and is commonly found in Greenlandic place names. It is so named because of its position at the end of t ...

Enclave
An enclave is a territory (or a small territory apart of a larger one) that is entirely surrounded by the territory of one other state or entity. Enclaves may also exist within territorial waters. ''Enclave'' is sometimes used improperly to denote a territory that is only partly surrounded by another state. The Vatican City and San Marino, both enclaved by Italy, and Lesotho, enclaved by South Africa, are completely enclaved sovereign states. An exclave is a portion of a state or district geographically separated from the main part by surrounding alien territory (of one or more states or districts etc). Many exclaves are also enclaves, but not all: an exclave can be surrounded by the territory of more than one state. The Azerbaijani exclave of Nakhchivan is an example of an exclave that is not an enclave, as it borders Armenia, Turkey and Iran. Semi-enclaves and semi-exclaves are areas that, except for possessing an unsurrounded sea border (a coastline contiguous with internat ...
