PFS Polarstern
RV ''Polarstern'' (meaning pole star) is a German research icebreaker of the Alfred Wegener Institute for Polar and Marine Research (AWI) in Bremerhaven, Germany. ''Polarstern'' was built by Howaldtswerke-Deutsche Werft in Kiel and Nobiskrug in Rendsburg, was commissioned in 1982, and is mainly used for research in the Arctic and Antarctica. The ship has a length of 118 metres (387 feet) and is a double-hulled icebreaker. She is operational at temperatures as low as . ''Polarstern'' can break through ice thick at a speed of . Thicker ice of up to can be broken by ramming. History On 7 September 1991, ''Polarstern'', assisted by the Swedish arctic icebreaker , reached the North Pole as the first conventional powered vessels. Both scientific parties and crew took oceanographic and geological samples and had a common tug of war and a football game on an ice floe. In 2001, ''Polarstern'' together with reached the pole again. She returned for a third time on 22 August 2011. This ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany

Double Hull
A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks. The space between the two hulls is sometimes used for storage of ballast water. Double hulls are a more extensive safety measure than double bottoms, which have two hull layers only in the bottom of the ship but not the sides. In low-energy collisions, double hulls can prevent flooding beyond the penetrated compartment. In high-energy collisions, however, the distance to the inner hull is not sufficient and the inner compartment is penetrated as well. Double hulls or double bottoms have been required in all passenger ships for decades as part of the Safety Of Life At Sea or SOLAS Convention. Uses Double hulls ...

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was COVID-19 pandemic in Hubei, identified in Wuhan, China, in December 2019. The disease quickly spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 are variable but often include fever, cough, headache, fatigue, breathing difficulties, Anosmia, loss of smell, and Ageusia, loss of taste. Symptoms may begin one to fourteen days incubation period, after exposure to the virus. At least a third of people who are infected Asymptomatic, do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, Hypoxia (medical), hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure ...

Fram Strait
The Fram Strait is the passage between Greenland and Svalbard, located roughly between 77°N and 81°N latitudes and centered on the prime meridian. The Greenland and Norwegian Seas lie south of Fram Strait, while the Nansen Basin of the Arctic Ocean lies to the north. Fram Strait is noted for being the only deep connection between the Arctic Ocean and the World Oceans. The dominant oceanographic features of the region are the West Spitsbergen Current on the east side of the strait and the East Greenland Current on the west. Description Fram Strait is the northernmost ocean area having ice-free conditions throughout the year. The width of the strait is about 450 km, but because of the wide continental shelves of Greenland and Spitsbergen, the deep portion of Fram Strait is only about 300 km wide. The ocean over the Greenland continental shelf is often covered with ice. Within Fram Strait, the sill connecting the Arctic and Fram Strait is 2545 m deep. The Knipo ...

MOSAiC Expedition
The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC, ) expedition was a one-year-long expedition into the Central Arctic (September 2019 - October 2020). For the first time a modern research icebreaker was able to operate in the direct vicinity of the North Pole year round, including the nearly half year long polar night during winter. In terms of the logistical challenges involved, the total number of participants, the number of participating countries, and the available budget, MOSAiC represents the largest Arctic expedition in history. During its one-year-long journey, the central expedition ship, the research icebreaker ''Polarstern'' from Germany's Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), was supported and resupplied by the icebreakers and research vessels ''Akademik Fedorov'' and '' Kapitan Dranitsyn'' (Russia), ''Sonne'' and '' Maria S. Merian'' (Germany) and ''Akademik Tryoshnikov'' (Russia). In additio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northwest Passage
The Northwest Passage (NWP) is the sea route between the Atlantic and Pacific oceans through the Arctic Ocean, along the northern coast of North America via waterways through the Canadian Arctic Archipelago. The eastern route along the Arctic coasts of Norway and Siberia is accordingly called the Northeast Passage (NEP). The various islands of the archipelago are separated from one another and from Mainland Canada by a series of Arctic waterways collectively known as the Northwest Passages, Northwestern Passages or the Canadian Internal Waters. For centuries, European explorers, beginning with Christopher Columbus in 1492, sought a navigable passage as a possible trade route to Asia, but were blocked by North, Central, and South America, by ice, or by rough waters (e.g. Tierra del Fuego). An ice-bound northern route was discovered in 1850 by the Irish explorer Robert McClure. Scotsman John Rae explored a more southerly area in 1854 through which Norwegian Roald Amundsen f ...

Northeast Passage
The Northeast Passage (abbreviated as NEP) is the shipping route between the Atlantic and Pacific Oceans, along the Arctic coasts of Norway and Russia. The western route through the islands of Canada is accordingly called the Northwest Passage (NWP). The NEP traverses (from west to east) the Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, and Chukchi Sea, and it includes the Northern Sea Route (NSR). The Northern Sea Route is a portion of the NEP. It is defined in Russian law and does not include the Barents sea and therefore does not reach the Atlantic Ocean. However, since the NSR has a significant overlap over the majority of the NEP, the NSR term is often used to refer to the entirety of the Northeast Passage. This practice injects confusion in understanding the specifics of both navigational procedures and jurisdiction. The Northeast Passage is one of several Arctic maritime routes, the others being the Northwest Passage (going through the Canadian Arctic Archipelago ...

Research Ship
A research vessel (RV or R/V) is a ship or boat designed, modified, or equipped to carry out research at sea. Research vessels carry out a number of roles. Some of these roles can be combined into a single vessel but others require a dedicated vessel. Due to the demanding nature of the work, research vessels may be constructed around an icebreaker hull, allowing them to operate in polar waters. History The research ship had origins in the early voyages of exploration. By the time of James Cook's ''Endeavour'', the essentials of what today we would call a research ship are clearly apparent. In 1766, the Royal Society hired Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. The ''Endeavour'' was a sturdy vessel, well designed and equipped for the ordeals she would face, and fitted out with facilities for her "research personnel", Joseph Banks. As is common with contemporary research vessels, ''Endeavour'' also carried out more than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neumayer Station
Neumayer-Station III, also known as Neumayer III after geophysicist Georg von Neumayer, is a German Antarctic research station of the Alfred-Wegener-Institut. It is located on the approximately thick Ekström Ice Shelf several kilometres south of Neumayer-Station II.DB mobil, Ausgabe 11, 2008 The station's assembly kit was transported to its current position early in November 2007. It is moving with the shelf ice at about per year towards the open sea. After almost ten years of work on the project, beginning in October 1999, including conception, environmental impact assessment, planning and construction phases, regular operation of the station began on 20 February 2009. The station replaces the Neumayer-Station II and the Georg-von-Neumayer-Station that preceded it. The expected lifespan of the station is 25 to 30 years and the entire project is estimated to cost €39 million. Construction phase The station was constructed above ground on a temporary two-level platform, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association Football
Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players who primarily use their feet to propel the ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposition by moving the ball beyond the goal line into a rectangular framed goal defended by the opposing side. Traditionally, the game has been played over two 45 minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries, it is considered the world's most popular sport. The game of association football is played in accordance with the Laws of the Game, a set of rules that has been in effect since 1863 with the International Football Association Board (IFAB) maintaining them since 1886. The game is played with a football that is in circumference. The two teams compete to get the ball into the other team's goal (between the posts and under t ...
