1985 Polar Sea Controversy
The 1985 Polar Sea controversy was a diplomatic event triggered by plans for the navigation of through the Northwest Passage from Greenland to Alaska without formal authorization from the Canadian government. It was the United States' position that the Northwest Passage was an international strait open to shipping and it sought only to notify Canada rather than ask for permission.Briggs, p.437 Publication of the plans enraged the Canadian public opinion as it was regarded as a breach and disregard of sovereignty and prompted the government to take preventive measures in defending Canada's arctic territories.Killaby, p.35 The U.S. never recognized Canada's claim over the Northwest passage but nevertheless, the two countries reached an agreement two years later which stipulated that in the future, the U.S. would ask permission before navigating the disputed waters. Canada's sovereignty over the region's waters was still a contentious issue as of 2010 and is likely to become of inc ... [...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 ...

Roald Amundsen
Roald Engelbregt Gravning Amundsen (, ; ; 16 July 1872 – ) was a Norwegian explorer of polar regions. He was a key figure of the period known as the Heroic Age of Antarctic Exploration. Born in Borge, Østfold, Norway, Amundsen began his career as a polar explorer as first mate on Adrien de Gerlache's Belgian Antarctic Expedition of 1897–1899. From 1903 to 1906, he led the first expedition to successfully traverse the Northwest Passage on the sloop ''Gjøa''. In 1909, Amundsen began planning for a South Pole expedition. He left Norway in June 1910 on the ship ''Fram'' and reached Antarctica in January 1911. His party established a camp at the Bay of Whales and a series of supply depots on the Barrier (now known as the Ross Ice Shelf) before setting out for the pole in October. The party of five, led by Amundsen, became the first to successfully reach the South Pole on 14 December 1911. Following a failed attempt in 1918 to reach the North Pole by traversing the ...

USCGC Polar Sea (WAGB 11)
USCGC ''Polar Sea'' (WAGB-11) is a United States Coast Guard heavy icebreaker. Commissioned on 23 February 1977, the ship was built by Lockheed Shipbuilding and Construction Company of Seattle along with her sister ship, ''Polar Star'' (WAGB-10). Her home port is Seattle, Washington. ''Polar Sea'' has been out of service due to failure of five of her six Alco main diesel engines. Machinery ''Polar Sea'' has a computerized propulsion control system to effectively manage six diesel-powered propulsion generators, three diesel-powered ship's service generators, three propulsion gas turbines, and other equipment vital to the operation of the ship. Its three shafts are each turned by either one gas turbine or two diesel-electric power plants. Each shaft is connected to a 16-foot (4.9-m) diameter, four-bladed, controllable-pitch propeller. For all three shafts, the diesel-electric plants can produce a total of 18,000 shaft horsepower (13,425 kilowatts) and the gas turbine plants ...

World Court
The International Court of Justice (ICJ; french: Cour internationale de justice, links=no; ), sometimes known as the World Court, is one of the six principal organs of the United Nations (UN). It settles disputes between states in accordance with international law and gives advisory opinions on international legal issues. The ICJ is the only international court that adjudicates general disputes between countries, with its rulings and opinions serving as primary sources of international law. The ICJ is the successor of the Permanent Court of International Justice (PCIJ), which was established in 1920 by the League of Nations. After the Second World War, both the league and the PCIJ were replaced by the United Nations and ICJ, respectively. The Statute of the ICJ, which sets forth its purpose and structure, draws heavily from that of its predecessor, whose decisions remain valid. All member states of the UN are party to the ICJ Statute and may initiate contentious cases; ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oil Tanker
An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets. Oil tankers are often classified by their size as well as their occupation. The size classes range from inland or coastal tankers of a few thousand metric tons of deadweight (DWT) to the mammoth ultra large crude carriers (ULCCs) of . Tankers move approximately of oil every year.UNCTAD 2006, p. 4. Second only to pipelines in terms of efficiency,Huber, 2001: 211. the average cost of transport of crude oil by tanker amounts to only US. Some specialized types of oil tankers have evolved. One of these is the naval replenishment oiler, a tanker which can fuel a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Warning System
The North Warning System (NWS) is a joint United States and Canadian early-warning radar system for the atmospheric air defense of North America. It provides surveillance of airspace from potential incursions or attacks from across North America's polar region. It replaced the Distant Early Warning Line system in the late 1980s. Overview The NWS consists of both long range AN/FPS-117 and short range AN/FPS-124 surveillance radars, operated and maintained by North American Aerospace Defense Command (NORAD). There are 13 long range sites and 36 short range sites. In Canada, the station sites are owned or leased by the Government of Canada, which also owns most of the infrastructure. The radars and tactical radios are owned by the United States Air Force. The Alaska Regional Operations Control Center (ROCC) at Elmendorf AFB, Alaska controls the stations in Alaska; the Canada East and Canada West Regional Operations Control Centres (ROCCs) at CFB North Bay, Ontario control the ...

Mid-Canada Line
The Mid-Canada Line (MCL), also known as the McGill Fence, was a line of radar stations running east–west across the middle of Canada, used to provide early warning of a Soviet bomber attack on North America. It was built to supplement the Pinetree Line, which was located farther south. The majority of Mid-Canada Line stations were used only briefly from the late 1950s to the mid-1960s, as the attack threat changed from bombers to ICBMs. As the MCL was closed down, the early warning role passed almost entirely to the newer and more capable DEW Line farther north. The MCL was based on the bistatic radar principle, using separated transmitters and receivers. An aircraft flying anywhere between the stations would reflect some of the transmitted signal towards the receiver, where it would mix with the signal travelling directly from the transmitter. The mixing of the two signals produces a pattern that is very easy to detect using simple electronics. As the transmitter is not pul ...

Pinetree Line
The Pinetree Line was a series of radar stations located across the northern United States and southern Canada at about the 50th parallel north, along with a number of other stations located on the Atlantic Ocean, Atlantic and Pacific coasts. Run by North American Aerospace Defense Command (NORAD) (after its creation), over half were staffed by United States Air Force personnel with the balance operated by the Royal Canadian Air Force. The line was the first coordinated system for early detection of a Soviet Union, Soviet bomber attack on North America, but before the early 1950s radar technology quickly became outdated and the line was in full operation only for a short time. History Plans for what would become the Pinetree Line were underway as early as 1946 within the Permanent Joint Board on Defense (PJBD), a Canadian-U.S. organization. However, the costs of running such a system in the post-war era was too high, and instead Canada concentrated on the areas around Ontari ...

DEW Line
The Distant Early Warning Line, also known as the DEW Line or Early Warning Line, was a system of radar stations in the northern Arctic region of Canada, with additional stations along the north coast and Aleutian Islands of Alaska (see Project Stretchout and Project Bluegrass), in addition to the Faroe Islands, Greenland, and Iceland. It was set up to detect incoming bombers of the Soviet Union during the Cold War, and provide early warning of any sea-and-land invasion. The DEW Line was the northernmost and most capable of three radar lines in Canada and Alaska. The first of these was the joint Canadian-United States Pinetree Line, which ran from Newfoundland to Vancouver Island just north of the Canada–United States border, but even while it was being built there were concerns that it would not provide enough warning time to launch an effective counterattack. The Mid-Canada Line (MCL) was proposed as an inexpensive solution using bistatic radar. This provided a "trip wir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
