St. Lewis, Newfoundland And Labrador
St. Lewis is a community on the coast of Labrador in the province of Newfoundland and Labrador, Canada. Formerly known as Fox Harbour, St. Lewis is the most easterly permanent community on the North American mainland. The community of St. Lewis enjoys a long and vibrant history as one of the earliest recorded places in all of Labrador by Europeans. Settled in the early 18th century (by Europeans), the area’s sheltered location, proximity to good fishing grounds and seal migration routes made the settlement a desired location for both the European-based migratory fishery, and the native Inuit families who inhabited the south Labrador coast. Geography The town lies neatly within a sheltered harbour at the mouth of St. Lewis Bay. Like most of the landscape along the east coast of Labrador, barren, rocky slopes scourged by the frigid Labrador Current extend throughout the St. Lewis Sound. The subarctic climate of the south Labrador coast generally offers a pleasant cool summer c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Provinces And Territories Of Canada
Canada has ten provinces and three territories that are sub-national administrative divisions under the jurisdiction of the Constitution of Canada, Canadian Constitution. In the 1867 Canadian Confederation, three provinces of British North America—New Brunswick, Nova Scotia, and the Province of Canada (which upon Confederation was divided into Ontario and Quebec)—united to form a federation, becoming a fully Independence, independent country over the next century. Over its history, Canada's international borders have changed several times as it has added territories and provinces, making it the List of countries and dependencies by area, world's second-largest country by area. The major difference between a Canadian province and a territory is that provinces receive their power and authority from the ''Constitution Act, 1867'' (formerly called the ''British North America Acts, British North America Act, 1867''), whereas territories are federal territories whose governments a ...

Subarctic
The subarctic zone is a region in the Northern Hemisphere immediately south of the true Arctic, north of hemiboreal regions and covering much of Alaska, Canada, Iceland, the north of Fennoscandia, Northwestern Russia, Siberia, and the Cairngorms. Generally, subarctic regions fall between 50°N and 70°N latitude, depending on local climates. Precipitation is usually low, and vegetation is characteristic of the taiga. Daylight at these latitudes is quite extreme between summer and winter due to its high latitude. Near the summer solstice for instance, subarctic regions can experience an all-night period of either civil, nautical, or astronomical twilight (or in the northern reaches full daylight), since the sun never dips more than 18 degrees below the horizon. Noctilucent clouds are best observed within this range of latitude. Climate and soils Subarctic temperatures are above for at least one and at most three months of the year. Precipitation tends to be low due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Coast Guard
The Canadian Coast Guard (CCG; ) is the coast guard of Canada. Formed in 1962, the coast guard is tasked with marine search and rescue (SAR), communication, navigation, and transportation issues in Canadian waters, such as navigation aids and icebreaking, marine pollution response, and support for other Canadian government initiatives. The Coast Guard operates 119 vessels of varying sizes and 23 helicopters, along with a variety of smaller craft. The CCG is headquartered in Ottawa, Ontario, and is a special operating agency within Fisheries and Oceans Canada (Department of Fisheries and Oceans). Role and responsibility Unlike armed coast guards of some other nations, the CCG is a government marine organization without naval or law enforcement responsibilities. Naval operations in Canada's maritime environment are exclusively the responsibility of the Royal Canadian Navy. Enforcement of Canada's maritime-related federal statutes may be carried out by peace officers serving w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LORAN
LORAN (Long Range Navigation) was a hyperbolic navigation, hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK's Gee (navigation), Gee system but operated at lower frequencies in order to provide an improved range up to with an accuracy of tens of miles. It was first used for ship convoys crossing the Atlantic Ocean, and then by long-range patrol aircraft, but found its main use on the ships and aircraft operating in the Pacific theater during World War II. LORAN, in its original form, was an expensive system to implement, requiring a cathode ray tube (CRT) display and a well trained operator. This limited use to the military and large commercial users. Automated receivers became available in the 1950s, but the same improved electronics also opened the possibility of new systems with higher accuracy. The U.S. Navy began development of Loran-B, which offered accuracy on the order of a few tens of feet, but ran into signi ...

Pinetree Line
The Pinetree Line was a series of radar stations located across southern Canada at about the 50th parallel north, along with a number of other stations located on the 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 bomber attack on North America. Its 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 Ontario and Quebec, while the United States set up stations in the Midwest and alon ...

Early-warning Radar
An early-warning radar is any radar system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as ''early'' as possible before the intruder reaches its target, giving the air defences the maximum time in which to operate. This contrasts with systems used primarily for tracking or gun laying, which tend to offer shorter ranges but offer much higher accuracy. EW radars tend to share a number of design features that improve their performance in the role. For instance, EW radar typically operates at lower frequencies, and thus longer wavelengths, than other types. This greatly reduces their interaction with rain and snow in the air, and therefore improves their performance in the long-range role where their coverage area will often include precipitation. This also has the side-effect of lowering their optical resolution, but this is not important in this role. Likewise, EW radars often use much lower pulse repetition frequency to maximi ...

Fox Harbour Air Station
Fox Harbour Air Station (ADC ID: N-27C) was a General Surveillance Gap Filler Radar station in St. Lewis in the Canadian province of Newfoundland and Labrador, It was located southeast of CFB Goose Bay. It was closed in 1961. History The site was established in 1957 as a staffed Gap Filler radar station, built by the United States Air Force, under operational control of Cartwright Air Station and part of the Pinetree Line of Ground-Control Intercept (GCI) radar sites. The station was assigned to Aerospace Defense Command in 1957, and was given designation "N-27C".

Harbour Grace
Harbour Grace is a town in Conception Bay on the Avalon Peninsula in the province of Newfoundland and Labrador, Canada. With roots dating back to the 16th century, it is one of the oldest towns in North America. It is located about northwest of the provincial capital, St. John's. The town has a population of 2,796 (2021), engaged primarily in fishing and fish processing. The alternative spelling of Harbor Grace was current at one time. History Early history The town was named after the French city of ''Havre de Grâce'', which is now known as Le Havre.Pitt J. and Pitt R.D., ''The Canadian Encyclopedia'',Harbour Grace" 2012. Accessed April 27, 2024ArchivedJune 28, 2022. Harbour Grace was an important port and fishing centre from the earliest days of European exploration of North America.

Atlantic Marine Ecozone
The Atlantic Marine Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a Canadian marine ecozone that stretches from the Davis Strait to encompass the Grand Banks, to the Avalon Peninsula on the shores of Newfoundland. It includes all of the southern coast of Newfoundland, all the eastern coast of Nova Scotia, and portions of the Bay of Fundy and the Gulf of Maine. Geography Most of the waters in this zone are thousands of metres deep, except the Grand Banks, which average about 150 metres before the sea floor drops precipitously beyond the continental shelf. Climate Exceptionally dense fog is common where the cold Labrador Current merges with the warm Gulf Stream. By late winter, thick icebergs traverse the northern regions of this ecozone, from Greenland to Newfoundland. They have been feared by mariners for centuries, as well as being responsible for one of the deadliest disasters in maritime history, the sinking of the RMS ''Titanic'' in 1912. ...

Iceberg
An iceberg is a piece of fresh water ice more than long that has broken off a glacier or an ice shelf and is floating freely in open water. Smaller chunks of floating glacially derived ice are called "growlers" or "bergy bits". Much of an iceberg is below the water's surface, which led to the expression " tip of the iceberg" to illustrate a small part of a larger unseen issue. Icebergs are considered a serious maritime hazard. Icebergs vary considerably in size and shape. Icebergs that calve from glaciers in Greenland are often irregularly shaped while Antarctic ice shelves often produce large tabular (table top) icebergs. The largest iceberg in recent history, named B-15, was measured at nearly in 2000. The largest iceberg on record was an Antarctic tabular iceberg measuring sighted west of Scott Island, in the South Pacific Ocean, by the USS ''Glacier'' on November 12, 1956. This iceberg was larger than Belgium. Etymology The word ''iceberg'' is a partial loan tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra
In physical geography, a tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: #Arctic, Arctic, Alpine tundra, Alpine, and #Antarctic, Antarctic. Tundra vegetation is composed of dwarf shrubs, Cyperaceae, sedges, Poaceae, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained greenhouse gases into the atmosphere, creating Climate change feedback, a feedback cycle t ...

Abies Balsamea
''Abies balsamea'' or balsam fir is a North American fir, native to most of eastern and central Canada (Newfoundland (island), Newfoundland west to central Alberta) and the northeastern United States (Minnesota east to Maine, and south in the Appalachian Mountains to West Virginia). Description Balsam fir is a small to medium-size evergreen tree typically tall, occasionally reaching a height of . The narrow conic crown consists of dense, dark-green leaves. The Bark (botany), bark on young trees is smooth, grey, and with resin blisters (which tend to spray when ruptured), becoming rough and fissured or scaly on old trees. The leaf, leaves are flat and needle-like, long, dark green above often with a small patch of stomata near the tip, and two white stomatal bands below, and a slightly notched tip. They are arranged spirally on the shoot, but with the leaf bases twisted so that the leaves appear to be in two more-or-less horizontal rows on either side of the shoot. The needles ...
