Uskmouth
Uskmouth ( cy, Aberwysg) is an area to the south of the city of Newport, South Wales. Location Uskmouth is effectively in the west of the village of Nash. It is at Uskmouth that the River Usk meets the Severn estuary. Amenities It includes part of the Newport Wetlands Reservebr> a notable wildlife reservebr> with reed beds and grasslands that attract breeding birds such as lapwings, redshanks, oystercatchers, little ringed plovers and ringed plovers, as well as visitors such as wigeons, shovelers, teals, shelducks and pintails, bitterns, hen harriers and short-eared owls. It is part of the Caldicot Levels. Following storms in the autumn of 1986, a track of human footprints was discovered eroding out of the clays in the intertidal zone in front of Uskmouth Power Station. The footprints were found to contain peat deposits, allowing them to be carbon dated to 4200BC. At the time they were the oldest known human footprints in Britain, but in 2013 footprints made about 80 ...

Uskmouth Power Station
The Uskmouth power stations (also known as the Fifoots Point power stations) refers to a series of two coal-fired power stations at the mouth of the River Usk in the south-east of Newport, Wales. The first of the two station, Uskmouth A power station, was built in the 1940s and demolished in 2002. The second station, Uskmouth B power station, was built in the 1950s and is currently undergoing a conversion to run on biomass and waste plastic. Uskmouth A Uskmouth A power station was authorised in 1947, and building started in April 1948. The first generating set was commissioned in December 1952, followed by other sets in September 1953, March 1954, September 1954, June 1956 and finally December 1956 for a set scrapped in January 1956. It comprised four Fraser and Chalmers / GEC 60 MW hydrogen cooled 11.8 kV turbo-alternators, these were supplied with steam at 62.1 bar and 482 °C.''CEGB Statistical Yearbook'', 1981, CEGB, London. The 12 Babcock and Wilcox pulverised fuel ...

Newport Wetlands Reserve
Newport Wetlands is a wildlife reserve covering parts of Uskmouth, Nash and Goldcliff, in the south-east of the city of Newport, South Wales. History The reserve was established in 2000 to mitigate losses of wildlife habitat when the Cardiff Bay Barrage scheme was undertaken. The site is owned and managed by Natural Resources Wales, the successor body to the Countryside Council for Wales. A purpose-built visitor and education centre for the site was opened, in West Nash, in March 2008 by the Royal Society for the Protection of Birds (RSPB) with help from Newport City Council and water level management assistance by Caldicot and Wentloog Levels Internal Drainage Board. The reserve covers of the Caldicot Level, a low-lying area of land bordering the northern shore of the Severn Estuary. Part of the site is a reclaimed fuel ash disposal site, although some farmland in Goldcliff and Nash has also had to be flooded to complete the work. The reserve was made a national natu ...

Nash, Newport
Nash ( cy, Trefonnen) is a village and community to the south of the city of Newport, South Wales, in the Lliswerry ward. Origin of the name The name is thought to originate from a contraction of "An Ash" (tree), meaning literally `place of the ash tree(s)'. This is supported by its appearance in deeds as "De Fraxino" ('' fraxinus'' was the Latin name for the ash tree). The Welsh name is ''Trefonnen'', given in older sources as ''Tre'r onnen'', also meaning Town (''tref'') of the Ash (''onnen''). Nash and nearby Goldcliff, as Nash and Goldcliffe, are two of the few villages to appear on the Cambriae Typus map of 1573. Location Nash lies about to the south of the built-up area of the city of Newport, on the Caldicot levels, a large area of land reclaimed from the sea and crossed by drainage channels and reens. In addition to the village itself, the parish contains Uskmouth power stations and part of the Newport Wetlands nature reserve, including its Visitors Cen ...

Newport, Wales
Newport ( cy, Casnewydd; ) is a city and county borough in Wales, situated on the River Usk close to its confluence with the Severn Estuary, northeast of Cardiff. With a population of 145,700 at the 2011 census, Newport is the third-largest authority with city status in Wales, and seventh most populous overall. Newport became a unitary authority in 1996 and forms part of the Cardiff-Newport metropolitan area. Newport was the site of the last large-scale armed insurrection in Great Britain, the Newport Rising of 1839. Newport has been a port since medieval times when the first Newport Castle was built by the Normans. The town outgrew the earlier Roman town of Caerleon, immediately upstream and now part of the borough. Newport gained its first charter in 1314. It grew significantly in the 19th century when its port became the focus of coal exports from the eastern South Wales Valleys. Newport was the largest coal exporter in Wales until the rise of Cardiff in the mid-180 ...

River Usk
The River Usk (; cy, Afon Wysg) rises on the northern slopes of the Black Mountain (''y Mynydd Du''), Wales, in the westernmost part of the Brecon Beacons National Park. Initially forming the boundary between Carmarthenshire and Powys, it flows north into Usk Reservoir, then east by Sennybridge to Brecon before turning southeast to flow by Talybont-on-Usk, Crickhowell and Abergavenny after which it takes a more southerly course. Beyond the eponymous town of Usk it passes the Roman legionary fortress of Caerleon to flow through the heart of the city of Newport and into the Severn Estuary at Uskmouth beyond Newport near the Newport Wetlands. The river is about long. The Monmouthshire and Brecon Canal follows the Usk for most of the length of the canal. Etymology The name of the river derives from a Common Brittonic word meaning "abounding in fish" (or possibly "water"), this root also appears in other British river names such as Exe, Axe, Esk and other variants. ...

Happisburgh Footprints
The Happisburgh footprints were a set of fossilized hominid footprints that date to the early Pleistocene, over 800,000 years ago. They were discovered in May 2013 in a newly uncovered sediment layer of the Cromer Forest Bed on a beach at Happisburgh in Norfolk, England, and carefully photographed in 3D before being destroyed by the tide shortly afterwards. Results of research on the footprints were announced on 7 February 2014 and identified them as the oldest known hominid footprints outside Africa.Ashton N, Lewis SG, De Groote I, Duffy SM, Bates M, et al. (201"Hominin Footprints from Early Pleistocene Deposits at Happisburgh, UK" ''PLoS ONE'' 9(2): e88329. Before the Happisburgh discovery, the oldest known footprints in Britain were at Uskmouth in South Wales, from the Mesolithic and carbon-dated to 4,600 BCE. The oldest known hominin footprints in Europe were the Ciampate del Diavolo tracks found at the Roccamonfina volcano in Italy, dated to around 350,000 years ago. ...

Caldicot And Wentloog Levels
The Caldicot and Wentloog Levels are two areas of low-lying estuarine alluvial wetland and intertidal mudflats adjoining the north bank of the Severn Estuary, either side of the River Usk estuary near Newport in south east Wales. They are also known collectively as the Monmouthshire Levels or Gwent Levels, and the name Wentloog is sometimes spelled Wentlooge in official publications. The Caldicot Level lies to the southeast of Newport between the River Usk and River Wye and consists of . It is home to Newport Wetlands Reserve. The Wentloog Level lies to the southwest between the River Usk and Rhymney River and consists of . The levels are formed from tidal deposits and alluvium, which have been recurrently inundated and reclaimed from the Severn Estuary by humans since Roman times. They have been patterns of settlement, enclosure and drainage systems belonging to successive periods of use, and are extremely rich archaeologically, with finds from the Mesolithic, Bronze Ag ...

Common Shelduck
The common shelduck (''Tadorna tadorna'') is a waterfowl species of the shelduck genus, ''Tadorna''. It is widespread and common in the Euro-Siberian region of the Palearctic, mainly breeding in temperate and wintering in subtropical regions; in winter, it can also be found in the Maghreb. Fossil bones from Dorkovo (Bulgaria) described as ''Balcanas pliocaenica'' may actually belong to this species. More likely, they are an extinct species of ''Tadorna'' (if not a distinct genus) due to their Early Pliocene age; the present species is not unequivocally attested from the fossil record until some 2–3 million years later (Late Pliocene/Early Pleistocene). Taxonomy The common shelduck was formally named by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Anas tadorna''. Linnaeus largely based his description on "The Sheldrake or Burrough-Duck" that had been described and illustrated in 1731 by the English nat ...

Archaeological Sites In Monmouthshire
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent o ...

Carbon 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 ca ...

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 the ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, oft ...
