Borth Campus (University Of Copenhagen)
Borth ( cy, Y Borth) is a village and seaside resort in Ceredigion, Mid Wales, 7 miles (11 km) north of Aberystwyth on the Ceredigion Coast Path. The community includes the settlement of Ynyslas. The population was 1,399 in 2011. From being largely Welsh-speaking, the village has become anglicised: over 54 per cent of its residents were born in England. According to both the 1991 and 2001 censuses, 43 per cent of the residents of Borth were primarily Welsh-speakers. Features and history Borth's sandy beach has helped to promote it as a seaside resort. There is a youth hostel in the village, and caravan and camping sites nearby. There is an ancient submerged forest visible at low tide along the beach, where stumps of oak, pine, birch, willow and hazel (preserved by the acid anaerobic conditions in the peat) can be seen. Radiocarbon dating suggests the trees date from about 1500 BCE. This submerged forest also ties in with the legend of Cantre'r Gwaelod. The s ...

Travel Trailer
A caravan, travel trailer, camper, tourer or camper trailer is a trailer towed behind a road vehicle to provide a place to sleep which is more comfortable and protected than a tent (although there are fold-down trailer tents). It provides the means for people to have their own home on a journey or a vacation, without relying on a motel or hotel, and enables them to stay in places where none is available. However, in some countries campers are restricted to designated sites for which fees are payable. Caravans vary from basic models which may be little more than a tent on wheels to those containing several rooms with all the furniture and furnishings and equipment of a home. Construction of the solid-wall trailers can be made of metal or fiberglass. Travel trailers are used principally in North America, Europe, Australia and New Zealand. History In Europe, the origins of travel trailers and caravanning can be traced back to the travelling Romani people, and showmen who spe ...

2018–19 European Windstorm Season
The 2018–2019 European windstorm season was the fourth instance of seasonal European windstorm naming in Europe. Most storms form between September and March. The first named storm, Ali, affected primarily the United Kingdom and Ireland on 19 September 2018. Background and naming In 2015, the British and Irish national meteorological agencies, Met Office and Met Éireann respectively, announced a pilot project to name storm warnings as part of the ''Name our Storms'' project for wind storms and asked the public for suggestions. The meteorological offices produced a full list of names for 2015–2016 through to 2017–2018, common to both the UK and Ireland. A new list of names was released on 11 September 2018 for the 2018–2019 season. Names in the UK were based on the National Severe Weather Warning Service, when a storm is assessed to have the potential for an Amber 'be prepared' or Red 'take action (danger to life)' warning. There are two main naming lists, created by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantre'r Gwaelod
, also known as or ( en, The Lowland Hundred), is a legendary ancient sunken kingdom said to have occupied a tract of fertile land lying between Ramsey Island and Bardsey Island in what is now Cardigan Bay to the west of Wales. It has been described as a "Welsh Atlantis" and has featured in folklore, literature, and song. The legend Cantre'r Gwaelod was an area of land which, according to legend, was located in an area west of present-day Wales which is now under the waters of Cardigan Bay. Accounts variously suggest the tract of land extended from Bardsey Island to Cardigan or as far south as Ramsey Island. Legends of the land suggest that it may have extended 20 miles west of the present coast. Rachel Bromwich questions this identification, saying that "There is no certainty, however, that in twelfth century tradition Maes Gwyddneu did represent the submerged land in Cardigan Bay." She also links Gwyddno Garanhir with the Hen Ogledd, not Wales. There are several ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. '' Sphagnum'' moss, also called peat moss, is one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypoxia (environmental)
Hypoxia refers to low oxygen conditions. Normally, 20.9% of the gas in the atmosphere is oxygen. The partial pressure of oxygen in the atmosphere is 20.9% of the total barometric pressure. In water, oxygen levels are much lower, approximately 7 ppm or 0.0007% in good quality water, and fluctuate locally depending on the presence of photosynthetic organisms and relative distance to the surface (if there is more oxygen in the air, it will diffuse across the partial pressure gradient). Atmospheric hypoxia Atmospheric hypoxia occurs naturally at high altitudes. Total atmospheric pressure decreases as altitude increases, causing a lower partial pressure of oxygen, which is defined as hypobaric hypoxia. Oxygen remains at 20.9% of the total gas mixture, differing from hypoxic hypoxia, where the percentage of oxygen in the air (or blood) is decreased. This is common in the sealed burrows of some subterranean animals, such as blesmols. Atmospheric hypoxia is also the basis of altitude ...

Hazel
The hazel (''Corylus'') is a genus of deciduous trees and large shrubs native to the temperate Northern Hemisphere. The genus is usually placed in the birch family Betulaceae,Germplasmgobills Information Network''Corylus''Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins .Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan . though some botanists split the hazels (with the hornbeams and allied genera) into a separate family Corylaceae. The fruit of the hazel is the hazelnut. Hazels have simple, rounded leaves with double-serrate margins. The flowers are produced very early in spring before the leaves, and are monoecious, with single-sex catkins. The male catkins are pale yellow and long, and the female ones are very small and largely concealed in the buds, with only the bright-red, 1-to-3 mm-long styles visible. The fruits are nuts long and 1–2 cm diameter, surrounded by an involucre (husk) which partly to fully encloses the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willow
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech- oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are a typically rather short-lived pioneer species widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from the alders (''Alnus'', another genus in the family) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family (biology), family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or Trinomial nomenclature, trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
