Jan Mayen
Jan Mayen () is a Norway, Norwegian volcanic island in the Arctic Ocean with no permanent population. It is long (southwest-northeast) and in area, partly covered by glaciers (an area of around the Beerenberg volcano). It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by a wide isthmus. It lies northeast of Iceland (495 km [305 mi] NE of Kolbeinsey), east of central Greenland, and northwest of Vesterålen, Norway. The island is mountainous, the highest summit being the Beerenberg volcano in the north. The isthmus is the location of the two largest lakes of the island, Sørlaguna (South Lagoon) and Nordlaguna (North Lagoon). A third lake is called Ullerenglaguna (Ullereng Lagoon). Jan Mayen was formed by the Jan Mayen hotspot and is defined by geologists as a Continental fragment, microcontinent. Although administered separately, in the ISO 3166-1 standard, Jan Mayen and Svalbard are collectively designated as ''Svalbard and Jan Mayen'' ...

Olonkinbyen
Olonkinbyen (literally ''The Olonkin Town'') is the only settlement on the Norwegian island of Jan Mayen in Svalbard and Jan Mayen (aside from isolated cottage huts such as Puppebu). It was named after Russian-Norwegian explorer Gennady Olonkin. The only inhabitants on the island are the 18 personnel, 14 working for the Norwegian Armed Forces and 4 for the Norwegian Meteorological Institute, but can have up to 35 people inhabiting the island at any given time. Olonkinbyen houses the staff that operate the meteorological observation station, Loran-C station, Jan Mayensfield air field and other infrastructure. The meteorological observation service staff are responsible for the radiosonde releases and synoptic weather observations. The crew of the meteorological station is engaged for six months at a time. Supplies are delivered eight times a year by aircraft. Fuel and heavy goods are transported by boat during the summer. The settlement generates its own electrical power vi ...

Beerenberg
Beerenberg is a stratovolcano dominating the northeastern end of the Norwegian island of Jan Mayen. It is high and is the world's northernmost subaerial active volcano and the List of volcanoes in Norway, only active volcano in Norway. The volcano is topped by a mostly ice-filled volcanic crater, crater about wide, with numerous peaks along its rim including the highest summit, Haakon VII Toppen, on its western side. Name Its name is Dutch language, Dutch for "Bear Mountain" and comes from the polar bears seen there by Dutch whalers in the early 17th century. Description The upper slopes of the volcano are largely ice-covered, with several major glaciers including five which reach the sea. The longest of the glaciers is the Weyprecht Glacier, which flows from the summit crater via a breach through the northwestern portion of the crater rim, and extends about down to the sea. Beerenberg is composed primarily of basaltic lava flows with minor amounts of tephra. Numerous c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Port
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhoushan.

Jan Mayensfield
Jan Mayensfield is an aerodrome serving Olonkinbyen in Jan Mayen, Norway. Operated by the Norwegian Armed Forces, it serves the island's only population at the combined military and meteorological station. It has a dirt runway numbered 04–22. The airfield was built in connection with the LORAN-C transmitter at Olonkinbyen and was completed in 1960. Jan Mayensfield is served eight times per year by Lockheed C-130 Hercules aircraft of the 335 Squadron from Bodø Main Air Station, which provide supplies and change crew at the outpost. The nearby Beerenberg volcano can cause a Kármán wind, which creates difficult landing conditions. History North Atlantic Treaty Organization (NATO) and the Norwegian Armed Forces started construction of a military communications outpost at Olonkinbyen in 1958. At first a LORAN-A transmitter was built, followed by a LORAN-C transmitter in 1960. In August, it was announced that the island would receive an airfield to allow continual operatio ...

Airstrip
An aerodrome, airfield, or airstrip is a location from which aircraft flight operations take place, regardless of whether they involve air cargo, passengers, or neither, and regardless of whether it is for public or private use. Aerodromes include small general aviation airfields, large commercial airports, and military air bases. The term ''airport'' may imply a certain stature (having satisfied certain certification criteria or regulatory requirements) that not all aerodromes may have achieved. That means that all airports are aerodromes, but not all aerodromes are airports. Usage of the term "aerodrome" (or "airfield") remains more common in Commonwealth English, and is conversely almost unknown in American English, where the term "airport" is applied almost exclusively. A water aerodrome is an area of open water used regularly by seaplanes, floatplanes or amphibious aircraft for landing and taking off. In formal terminology, as defined by the International Civil ...

Meteorological
Meteorology is the scientific study of the Earth's atmosphere and short-term atmospheric phenomena (i.e. weather), with a focus on weather forecasting. It has applications in the military, aviation, energy production, transport, agriculture, construction, weather warnings and disaster management. Along with climatology, atmospheric physics and atmospheric chemistry, meteorology forms the broader field of the atmospheric sciences. The interactions between Earth's atmosphere and its oceans (notably El Niño and La Niña) are studied in the interdisciplinary field of hydrometeorology. Other interdisciplinary areas include biometeorology, space weather and planetary meteorology. Marine weather forecasting relates meteorology to maritime and coastal safety, based on atmospheric interactions with large bodies of water. Meteorologists study meteorological phenomena driven by solar radiation, Earth's rotation, ocean currents and other factors. These include everyday wea ...

Radio Communications
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravel
Gravel () is a loose aggregation of rock fragments. Gravel occurs naturally on Earth as a result of sedimentation, sedimentary and erosion, erosive geological processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by grain size, particle size range and includes size classes from granule (geology), granule- to boulder-sized fragments. In the grain size, Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges for fine and for coarse. One cubic metre of gravel typically weighs about , or one cubic yard weighs about . Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as construction aggregate, aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without bitumen, asphalt or other binders.) Natu ...

Subaerial Eruption
In volcanology, a subaerial eruption is any sort of volcanic eruption that occurs on the land surface, or in the open air "under the air". They generally produce pyroclastic flows, lava fountains and lava flows, which are commonly classified in different subaerial eruption types, including Plinian, Peléan and Hawaiian eruptions. Subaerial eruptions contrast with subaqueous, submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.)
