Tanquary Fiord
Tanquary Fiord is a fjord on the north coast of the Arctic Archipelago's Ellesmere Island, Nunavut, Canada. It is located in the Quttinirpaaq National Park and extends in a north-westerly direction from Greely Fiord. History Radiocarbon dating methods suggest that between 10,000 and 4,100 BP, deglaciation occurred, followed by a period of glacial readvance and the formation of ice shelves until 2,400 BP. Until 1,400 BP, a period of glacial retreat occurred, and since then glacial readvance and nearby ice rises have marked the area. Radiocarbon analysis of charcoal undertaken by the Geological Survey of Canada has shown that Inuit were present at Tanquary Fiord around 1070 BP at the latest. Geography The head of the Tanquary Fiord is the convergence point of four river valleys, three of which end in a floodplain and one in a river delta. Carbon dating findings show that the fjord was free of glacial ice approximately 6,500 years ago. In the past 40 years, the terminal poi ...

Quttinirpaaq National Park
Quttinirpaaq National Park is located on the northeastern corner of Ellesmere Island in the Qikiqtaaluk Region of Nunavut, Canada. It is the second most northerly park on Earth after Northeast Greenland National Park. In Inuktitut, Quttinirpaaq means "top of the world". It was established as Ellesmere Island National Park Reserve in 1988, and the name was changed to Quttinirpaaq in 1999, when Nunavut was created, and became a national park in 2000. The reserve covers , making it the second largest park in Canada, after Wood Buffalo National Park. The park is remarkable for its extensive glaciers and ice caps, desert-like conditions, and life forms that are uniquely adapted to the extreme polar environment. Only about 50 people visit the park each year. Landscape The land is dominated by rock and ice. It is a polar desert with very little annual precipitation. Much of the highlands of the park are covered in ice caps. These ice caps, and the glaciers that descend from them, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanquary Fiord Airport
Tanquary Fiord Airport is located at the southern side of Tanquary Fiord, Nunavut, Canada, close to the end of the fiord. It is located within Quttinirpaaq National Park and is maintained by Parks Canada. It serves as the main access to the park for tourists. Hikers to Lake Hazen, which is located to the northeast, start from Tanquary Camp. The aerodrome sketch for Tanquary Fiord is probably the simplest in the Canada Flight Supplement; it has nothing on it but a runway and an unlit wind sock A windsock (also called a wind cone) is a conical textile tube that resembles a giant sock. It can be used as a basic indicator of wind speed and direction, or as decoration. They are typically used at airports to show the direction and stren ....

Carbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be use ...

Donald Baxter MacMillan
Donald Baxter MacMillan (November 10, 1874 – September 7, 1970) was an American explorer, sailor, researcher and lecturer who made over 30 expeditions to the Arctic during his 46-year career. He pioneered the use of radios, airplanes, and electricity in the Arctic and put together a dictionary of the Inuktitut language. His expeditions produced Inuit films, photographs of Arctic scenes, and audio recordings of Inuit languages, thousands of which were taken by Miriam MacMillan. In 1921, he designed the ''Bowdoin'' schooner (named for Bowdoin College), which sailed to the Arctic two dozen times. Early life Born in Provincetown, Massachusetts in 1874, MacMillan lived in Freeport, Maine after the deaths of both his parents in 1883 (his father died while captaining a Grand Banks fishing schooner) and 1886 (his mother died suddenly), and was educated at Bowdoin College in Brunswick, graduating in 1898 with a degree in geology. He later taught at Worcester Academy fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meteorological Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments Typical weather stations have the following instruments: * Thermometer for ...

Icebreaker
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hu ...

Charter Airline
Air charter is the business of renting an entire aircraft (i.e., chartering) as opposed to individual aircraft seats (i.e., purchasing a ticket through a traditional airline). Regulation Charter – also called air taxi or ad hoc – flights require certification from the associated country's civil aviation authority. The regulations are differentiated from typical commercial/passenger service by offering a non-scheduled service. Analogous regulations generally also apply to air ambulance and cargo operators, which are often also ad hoc for-hire services. United States In the U.S. these flights are regulated under FAA Part 135. There are some cases where a charter operator can sell scheduled flights, but only in limited quantities. As of 2021, the FAA had made it a priority to crack down on unauthorised charter flights, according to industry experts. Types of service There are several business models which offer air charter services from the traditional charter operator to br ...
