Blanket Bog
Blanket bog or blanket mire, also known as featherbed bog, is an area of peatland, forming where there is a climate of high rainfall and a low level of evapotranspiration, allowing peat to develop not only in wet hollows but over large expanses of undulating ground. The blanketing of the ground with a variable depth of peat gives the habitat type its name. Blanket bogs are found extensively throughout the northern hemisphere - well-studied examples are found in Ireland and Scotland, but vast areas of North American tundra also qualify as blanket bogs. In Europe, the southernmost edge of range of this habitat has been recently mapped in the Cantabrian Mountains, northern Spain, but the current distribution of blanket bogs globally remains unknown. In the southern hemisphere they are less well-developed due to the relatively low latitudes of the main land areas, though similar environments are reported in Patagonia, the Falkland Islands and New Zealand. The blanket bogs known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falkland Islands
The Falkland Islands (; ), commonly referred to as The Falklands, is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and from Cape Dubouzet at the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland, and 776 smaller islands. As a British Overseas Territory, the Falklands have internal self-governance, while the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley, Falkland Islands, Stanley on East Falkland. The islands are believed to have been uninhabited prior to European discovery in the 17th century. Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times, the islands have had French, British, Spanish, and Argentine settlements.

Bogs
A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials often mosses, typically sphagnum moss. It is one of the four main Wetland#Types, types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A bayhead is another type of bog found in the forest of the Gulf Coast states in the United States.Watson, Geraldine Ellis (2000) ''Big Thicket Plant Ecology: An Introduction'', Third Edition (Temple Big Thicket Series #5). University of North Texas Press. Denton, Texas. 152 pp. Texas Parks and Wildlife. Ecological Mapping Systems of Texas:West Gulf Coastal Plain Seepage Swamp and Baygall. Retrieved 7 July 2020 They are often covered in Ericaceae, heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. Bogs occur where the water at the ground surface is acidic and low in nutrients. A bog usually is ...

String Bog
A string bog or string mire is a bog consisting of slightly elevated ridges and islands, with woody plants, alternating with flat, wet sedge mat areas. String bogs occur on slightly sloping surfaces, with the ridges at right angles to the direction of water flow. They are an example of patterned vegetation. String bogs are also known as aapa moors or aapa mires (from Finnish ''aapasuo'') or Strangmoor (from the German). A string bog has a pattern of narrow (2–3m wide), low (less than 1m high) ridges oriented at right angles to the direction of drainage with wet depressions or pools occurring between the ridges. The water and peat are very low in nutrients because the water has been derived from other ombrotrophic wetlands, which receive all of their water and nutrients from precipitation rather than from streams or springs. The peat thickness is greater than 1m. String bogs are features associated with periglacial climates, where the temperature results in long periods of ...

Electricity Generation
Electricity generation is the process of generating electric power from sources of primary energy. For electric utility, utilities in the electric power industry, it is the stage prior to its Electricity delivery, delivery (Electric power transmission, transmission, Electric power distribution, distribution, etc.) to end users or its Grid energy storage, storage, using for example, the Pumped-storage hydroelectricity, pumped-storage method. Consumable electricity is not freely available in nature, so it must be "produced", transforming other forms of energy to electricity. Production is carried out in power stations, also called "power plants". Electricity is most often generated at a power plant by electromechanical electric generator, generators, primarily driven by heat engines fueled by combustion or nuclear fission, but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bord Na Móna
Bord na Móna (; English: "The Peat Board") is a semi-state company in Ireland, created in 1946 by the Turf Development Act 1946. The company began developing the peatlands of Ireland with the aim to provide economic benefit for Irish Midland communities and achieve security of energy supply for the recently formed Irish Republic. The development of peatlands involved the mechanised harvesting of peat, which took place primarily in the Midlands of Ireland. Over the years, Bord na Móna has expanded and diversified its portfolio of businesses to include biomass procurement and supply, power generation (peat based and renewable), waste recovery, domestic fuel products and professional and consumer horticulture products. In 2015, the company announced that the harvesting of peat for power generation is to be "phased out" by 2030, at which point the company would complete its transition to new sustainable businesses located across its bogs and landholding. The new sustainable busin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fossil Fuel
A fossil fuel is a flammable carbon compound- or hydrocarbon-containing material formed naturally in the Earth's crust from the buried remains of prehistoric organisms (animals, plants or microplanktons), a process that occurs within geological formations. Reservoirs of such compound mixtures, such as coal, petroleum and natural gas, can be extracted and burnt as fuel for human consumption to provide energy for direct use (such as for cooking, heating or lighting), to power heat engines (such as steam or internal combustion engines) that can propel vehicles, or to generate electricity via steam turbine generators. Some fossil fuels are further refined into derivatives such as kerosene, gasoline and diesel, or converted into petrochemicals such as polyolefins ( plastics), aromatics and synthetic resins. The origin of fossil fuels is the anaerobic decomposition of buried dead organisms. The conversion from these organic materials to high-carbon fossil fuels is ty ...

Deforestation
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage. The direct cause of most deforestation is agriculture by far. More than ...

Macquarie Island
Macquarie Island is a subantarctic island in the south-western Pacific Ocean, about halfway between New Zealand and Antarctica. It has been governed as a part of Tasmania, Australia, since 1880. It became a Protected areas of Tasmania, Tasmanian State Reserve in 1978 and was inscribed as a UNESCO World Heritage Site in 1997. Macquarie Island is an exposed portion of the Macquarie Fault Zone, Macquarie Ridge and is located where the Australian Plate meets the Pacific Plate. The island is home to the entire royal penguin population during their annual nesting season. Ecologically, the island is part of the Antipodes Subantarctic Islands tundra ecoregion. History 19th century Frederick Hasselborough, an Australian, discovered the uninhabited island on 11 July 1810, while looking for new seal hunting, sealing grounds.
