Cape Atholl
Cape Atholl ( da, Kap Atholl), also known as Kangaarasuk, is a headland in Northwest Greenland, Avannaata municipality. This cape was named by Commander James Saunders, after Atholl, the class to which his ship HMS ''North Star'' belonged, during the winter 1849–50 in which he was frozen in the bay to the north and named landmarks in the area. History ''Cape Atholl'' was a United States Coast Guard LORAN station in Northwest Greenland, south of Thule Air Base. It was established in 1954 and disestablished in 1975. The station was located at Quaratit, about southeast of Cape Atholl proper. *Latitude: 76°18'56.62"N *Longitude: 69°21'21.03"W Geography Cape Atholl is located in the mainland, in the eastern shore of Bylot Sound, Baffin Bay. It rises at the southern end of the mouth of Wolstenholme Fjord and opposite the eastern end of Wolstenholme Island.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute'', p. 85 References External linksGreenland Pilot - Dani ...

Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

LORAN
LORAN, short for long range navigation, was a hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK's Gee system but operated at lower frequencies in order to provide an improved range up to with an accuracy of tens of miles. It was first used for ship convoys crossing the Atlantic Ocean, and then by long-range patrol aircraft, but found its main use on the ships and aircraft operating in the Pacific theater during World War II. LORAN, in its original form, was an expensive system to implement, requiring a cathode ray tube (CRT) display. This limited use to the military and large commercial users. Automated receivers became available in the 1950s, but the same improved electronics also opened the possibility of new systems with higher accuracy. The U.S. Navy began development of Loran-B, which offered accuracy on the order of a few tens of feet, but ran into significant technical problems. The U.S. Air Force worked on a ...

Headlands Of Greenland
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operational Navigation Chart B-8, 3rd Edition
An operational definition specifies concrete, replicable procedures designed to represent a construct. In the words of American psychologist S.S. Stevens (1935), "An operation is the performance which we execute in order to make known a concept." For example, an operational definition of "fear" (the construct) often includes measurable physiologic responses that occur in response to a perceived threat. Thus, "fear" might be operationally defined as specified changes in heart rate, galvanic skin response, pupil dilation, and blood pressure. Overview An operational definition is designed to model or represent a concept or theoretical definition, also known as a construct. Scientists should describe the operations (procedures, actions, or processes) that define the concept with enough specificity such that other investigators can replicate their research. Operational definitions are also used to define system states in terms of a specific, publicly accessible process of preparation ...

Wolstenholme Island
Wolstenholme Island ( kl, Qeqertarssuaq) is an island in Baffin Bay, in Avannaata municipality, off northwestern Greenland. The island lies west of the Bylot Sound off Cape Atholl in the southern shore of the mouth of Wolstenholme Fjord, south of Saunders Island, Greenland, Saunders Island. It is smaller than the latter and made of gneiss. History Under Commander James Saunders (naval commander), James Saunders HMS North Star (1824), HMS ''North Star'' sailed to the Arctic in 1849 in the spring on a venture to search and resupply Captain Sir James Clark Ross' expedition, who in turn had sailed in 1848 trying to locate the whereabouts of Sir John Franklin's expedition. Failing to find Franklin or Ross, Saunders's mission aboard the ''North Star'' consisted in depositing stores along several named areas of the Canadian Arctic coast and returning to England before the onset of winter. However, James Saunders's ship's progress was hindered by large amounts of ice in Melville Bay and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolstenholme Fjord
Wolstenholme Fjord ( kl, Uummannap Kangerlua) is a fjord in Avannaata municipality, Northwest Greenland. It is located to the north of the Thule Air Base and adjacent to the abandoned Inuit settlement of Narsaarsuk. The area was contaminated in 1968 with plutonium and other radioactive elements following a B-52 bomber crash. Geography Wolstenholme Fjord is located in the stretch of coast between Cape York and Cape Alexander. Together with the Inglefield Gulf it is one of the two main indentations in the area.''Prostar Sailing Directions 2005 Greenland and Iceland Enroute,'' p. 77 Saunders Island, Wolstenholme Island and the Bylot Sound lie at the mouth of the Fjord in North Star Bay. Further to the west on the northern shore lies the Granville Fjord.

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, located north of the Arctic Circle and from the North Pole on the northwest coast of the island of Greenland.

Bylot Sound
The Bylot Sound is a sound in the North Star Bay, Avannaata municipality, northwest Greenland. Geography This channel separates Saunders Island and Wolstenholme Island from the Greenland mainland. Its minimum width is , between Wolstenholme Island and Cape Atholl, the mainland point at its southeastern end. There is a tombolo named ''Uummannaq'' on the mainland shore at the eastern end of the sound by the former settlement of Pituffik. History This strait was named after 17th-century English navigator Robert Bylot, who led two expeditions to find the Northwest Passage. In the winter of 1849–1850 under Commander James Saunders of got frozen-in in the sound during an Arctic expedition to search and resupply Captain Sir James Clark Ross' venture, who in turn had sailed in 1848 trying to locate the whereabouts of Sir John Franklin's expedition.
