Nanisivik Mine
Nanisivik Mine was a zinc-lead mine in the company town of Nanisivik, Nunavut, north of the Arctic Circle on Baffin Island. It was Canada's first mine in the Arctic. The mine first opened on 15 October 1976 and permanently closed in September 2002 due to low metal prices and declining resources. Mine reclamation began in April 2003. It was one of the most northerly mines in the world. The mine was served by a port and dock located about north. It was used for shipping concentrate from the site, and receiving supplies. It is currently used by the Canadian Coast Guard for training and is intended to become Nanisivik Naval Facility. The mine also had its own airport ( Nanisivik Airport) located about southwest and was the main airport for Arctic Bay, until they expanded the Arctic Bay Airport. The airport is about directly southeast of Arctic Bay but the road between them is . [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanisivik
Nanisivik ( iu, ᓇᓂᓯᕕᒃ, lit=the place where people find things; ) is a now-abandoned company town which was built in 1975 to support the lead-zinc mining and mineral processing operations for the Nanisivik Mine, in production between 1976 and 2002. The townsite is located just inland from Strathcona Sound, about east of the community of Arctic Bay in the Canadian territory of Nunavut. There is a port and dock about north of the abandoned mine site, which was used for shipping concentrate from the site, and receiving supplies (). It is used by the Canadian Coast Guard for training. Nanisivik Airport, located south, was used as the main airport for Arctic Bay until 2010, when the lengthened Arctic Bay Airport took over. The airport is about directly southeast of Arctic Bay but the road between them is . Demographics In the 2021 Canadian census conducted by Statistics Canada, Nanisivik had a population of 0, no change from its 2016 population of 0. With a land ...

Nanisivik Naval Facility
The Nanisivik Naval Facility (french: links=no, installation navale de Nanisivik) is a Canadian Forces naval facility on Baffin Island, Nunavut. The station is built at the former lead-zinc mine site near the former company town of Nanisivik. The facility was undergoing final testing in mid-2019. Full operational capability had been expected to be achieved by mid-2020 with the first refuelling of a Royal Canadian Navy ship. However, in July 2020 it was confirmed that work on the facility would not be completed until 2022. On 30 March 2022, it was reported that the completion of the facility would be further delayed to 2023. Then in November 2022, the Auditor General of Canada reported that the facility would only actually start to be used by the Navy beginning in 2025. Description The naval station was originally planned to be home port of the Arctic offshore patrol ships that were proposed under the Harper government plan. These ships have ice-breaking capability and help the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc Mines In Canada
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the secon ...

Lead Mines In Canada
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polar Climate
The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month in a polar climate has an average temperature of less than . Regions with polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles, and in this case, winter days are extremely short and summer days are extremely long (could last for the entirety of each season or longer). A polar climate consists of cool summers and very cold winters, which results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice. It is identified with the letter E in the Köppen climate classification. Subtypes There are two types of polar climate: ET, or tundra climate; and EF, or ice cap climate. A tundra climate is characterized by having at least one month whose average temperature is above , while an ice cap climate has no months averaging above . In a tundra climate, even coniferous trees cannot grow, but o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, 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 g ...
