Weather Station Kurt
Weather Station Kurt (Wetter-Funkgerät Land-26) was an automatic weather station, erected by a German U-boat crew in northern Labrador, Dominion of Newfoundland, in October 1943. Installing the equipment for the station was the only known armed German military operation on land in North America during the Second World War. After the war it was forgotten until its rediscovery in 1977. Background In the northern hemisphere, weather systems in temperate climates predominantly move from west to east. This gave the Allies an important advantage. The Allied network of weather stations in North America, Greenland, and Iceland allowed the Allies to make more accurate weather forecasts than the Germans. German meteorologists used weather reports sent by U-boats and weather ships, such as ''Lauenburg'', operating in the North Atlantic. They also had reports from clandestine weather stations in remote parts of the Arctic and readings collected over the Atlantic by specially equipped we ...

Dominion Of Newfoundland
Newfoundland was a British dominion in eastern North America, today the modern Canadian province of Newfoundland and Labrador. It was established on 26 September 1907, and confirmed by the Balfour Declaration of 1926 and the Statute of Westminster of 1931. It included the island of Newfoundland, and Labrador on the continental mainland. Newfoundland was one of the original dominions within the meaning of the Balfour Declaration and accordingly enjoyed a constitutional status equivalent to the other dominions of the time. In 1934, Newfoundland became the only dominion to give up its self-governing status, which ended 79 years of self-government. The abolition of self-government came about because of a crisis in Newfoundland's public finances in 1932. Newfoundland had accumulated a significant amount of debt by building a railway across the island, which was completed in the 1890s, and by raising its own regiment during World War I. In November 1932, the government warned th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telemetry
Telemetry is the in situ collection of measurements or other data at remote points and their automatic transmission to receiving equipment (telecommunication) for monitoring. The word is derived from the Greek roots ''tele'', "remote", and ''metron'', "measure". Systems that need external instructions and data to operate require the counterpart of telemetry, telecommand. Although the term commonly refers to wireless data transfer mechanisms (e.g., using radio, ultrasonic, or infrared systems), it also encompasses data transferred over other media such as a telephone or computer network, optical link or other wired communications like power line carriers. Many modern telemetry systems take advantage of the low cost and ubiquity of GSM networks by using SMS to receive and transmit telemetry data. A ''telemeter'' is a physical device used in telemetry. It consists of a sensor, a transmission path, and a display, recording, or control device. Electronic devices are widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Chidley
Cape Chidley is a headland located on the eastern shore of Killiniq Island, Canada, at the northeastern tip of the Labrador Peninsula. Cape Chidley was named by English explorer John Davis on August 1, 1587, after his friend and fellow explorer John Chidley. On October 22, 1943, the landed just south of Cape Chidley and set up Weather Station Kurt to collect data about the weather. Originally, Cape Chidley was meant to be the site for a long-range radar station called "N-30." It was to fall within plans for the Pinetree Line, a series of radar stations across the 50th parallel. Supplies were moved to the site by ship during 1951–52, but in late 1952–early 1953 the site was moved to Resolution Island.The Pinetree LineThe Mystery of Site N-30 Oct, 2002 Location Sometimes spelled ''Cape Chudleigh'', Cape Chidley is located on the short boundary between the province of Newfoundland and Labrador and the territory of Nunavut on Killniq Island.

2 Cm FlaK 30/38/Flakvierling
The Flak 30 (''Flugzeugabwehrkanone 30'') and improved Flak 38 were 20 mm anti-aircraft guns used by various German forces throughout World War II. It was not only the primary German light anti-aircraft gun but by far the most numerously produced German artillery piece throughout the war. It was produced in a variety of models, notably the Flakvierling 38 which combined four Flak 38 autocannons onto a single carriage. Development The Germans fielded the unrelated early 2 cm Flak 28 just after World War I, but the Treaty of Versailles outlawed these weapons and they were sold to Switzerland. The original Flak 30 design was developed from the Solothurn ST-5 as a project for the Kriegsmarine, which produced the 20 mm C/30. The gun fired the "Long Solothurn", a 20 × 138 mm belted cartridge that had been developed for the ST-5 and was one of the more powerful 20 mm rounds. The C/30, featuring a barrel length of 65 calibres, had a fire rate of ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kiel
Kiel () is the capital and most populous city in the northern German state of Schleswig-Holstein, with a population of 246,243 (2021). Kiel lies approximately north of Hamburg. Due to its geographic location in the southeast of the Jutland peninsula on the southwestern shore of the Baltic Sea, Kiel has become one of Germany's major maritime centres, known for a variety of international sailing events, including the annual Kiel Week, which is the biggest sailing event in the world. Kiel is also known for the Kiel Mutiny, when sailors refused to board their vessels in protest against Germany's further participation in World War I, resulting in the abdication of the Kaiser and the formation of the Weimar Republic. The Olympic sailing competitions of the 1936 and the 1972 Summer Olympics were held in the Bay of Kiel. Kiel has also been one of the traditional homes of the German Navy's Baltic fleet, and continues to be a major high-tech shipbuilding centre. Located in Kiel ...

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive hydraulic shock. Most depth charges use high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a " nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a surface ship, or anot ...

Spitsbergen
Spitsbergen (; formerly known as West Spitsbergen; Norwegian: ''Vest Spitsbergen'' or ''Vestspitsbergen'' , also sometimes spelled Spitzbergen) is the largest and the only permanently populated island of the Svalbard archipelago in northern Norway. Constituting the westernmost bulk of the archipelago, it borders the Arctic Ocean, the Norwegian Sea, and the Greenland Sea. Spitsbergen covers an area of , making it the largest island in Norway and the 36th-largest in the world. The administrative centre is Longyearbyen. Other settlements, in addition to research outposts, are the Russian mining community of Barentsburg, the research community of Ny-Ålesund, and the mining outpost of Sveagruva. Spitsbergen was covered in of ice in 1999, which was approximately 58.5% of the island's total area. The island was first used as a whaling base in the 17th and 18th centuries, after which it was abandoned. Coal mining started at the end of the 19th century, and several permanent com ...

Bear Island (Norway)
Bear Island ( no, Bjørnøya, ) is the southernmost island of the Norway, Norwegian Svalbard, Svalbard archipelago. The island is located in the western part of the Barents Sea, approximately halfway between Spitsbergen and the North Cape, Norway, North Cape. Bear Island was discovered by Dutch explorers Willem Barentsz and Jacob van Heemskerck on 10 June 1596. It was named after a polar bear that was seen swimming nearby. The island was considered terra nullius until the Spitsbergen Treaty of 1920 placed it under Norwegian sovereignty. Despite its remote location and barren nature, the island has seen commercial activities in past centuries, such as coal mining, fishing and whaling. However, no settlements have lasted more than a few years, and Bear Island is now uninhabited except for personnel working at the island's meteorological station ''Herwighamna''. Along with the adjacent waters, it was declared a nature reserve in 2002. History Seafarers of the Viking Age, Viking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its f ...
