River Ock
The River Ock is a small English river which is a tributary of the River Thames. It has as its catchment area the Vale of White Horse, a low-lying and wide valley in south Oxfordshire, and flows into the River Thames, at Abingdon on the reach above Culham Lock. Course The River Ock rises near the village of Little Coxwell. It collects tributaries from each village along the base of the White Horse Hills, where springs emanating from the chalk hills allowed settlements to flourish in former times. Among these tributaries is the Osse Stream, rising in Cumnor. From Little Coxwell, the Ock runs around Longcot and flows past Stanford in the Vale, where it is about wide. The name of Stanford comes from ''stony ford'', possibly alluding to the Ock crossing at Stanford Mill. Thence it runs past Charney Bassett, Lyford, Garford and Marcham Mill, before losing its identity and its waters to the Thames at Abingdon by the old Hygienic Laundry building. An iron bridge crosses at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abingdon, Oxfordshire
Abingdon-on-Thames ( ), commonly known as Abingdon, is a historic market town and civil parish in the ceremonial county of Oxfordshire, England, on the River Thames. Historically the county town of Berkshire, since 1974 Abingdon has been administered by the Vale of White Horse district within Oxfordshire. The area was occupied from the early to middle Iron Age and the remains of a late Iron Age and Roman defensive enclosure lies below the town centre. Abingdon Abbey was founded around 676, giving its name to the emerging town. In the 13th and 14th centuries, Abingdon was an agricultural centre with an extensive trade in wool, alongside weaving and the manufacture of clothing. Charters for the holding of markets and fairs were granted by various monarchs, from Edward I to George II. The town survived the dissolution of the abbey in 1538, and by the 18th and 19th centuries, with the building of Abingdon Lock in 1790, and Wilts & Berks Canal in 1810, was a key link between ...

Charney Bassett
Charney Bassett is a village and civil parish about north of Wantage and east of Faringdon in the Vale of White Horse. It was part of Berkshire until the 1974 boundary changes transferred it to Oxfordshire. The 2011 Census recorded the parish population as 314. The River Ock flows through it, and divides here for a mile or so. The alternative name of the river, ''Charn'' or ''Cearn'', may have originally applied to the northern arm only. Archaeology In 1978 Thames Water dredged a prehistoric flint axe-head from the River Ock in the parish. About north of the village, between Charney and Pusey is Cherbury Camp, an Iron Age earthwork. It looks like the nearby hill forts on the Berkshire Downs but is unusual in being built on more or less level ground, away from any hill. Cherbury means "fort beside the River Cearn". It is larger than Uffington Castle hill fort. History Charney Bassett has been settled since the Anglo-Saxon era. The earliest known records of the localit ...

Hydronym
A hydronym (from el, ὕδρω, , "water" and , , "name") is a type of toponym that designates a proper name of a body of water. Hydronyms include the proper names of rivers and streams, lakes and ponds, swamps and marshes, seas and oceans. As a subset of toponymy, a distinctive discipline of ''hydronymy'' (or ''hydronomastics'') studies the proper names of all bodies of water, the origins and meanings of those names, and their development and transmission through history. Classification by water types Within the onomastic classification, main types of hydronyms are (in alphabetical order): * helonyms: proper names of swamps, marshes and bogs, * limnonyms: proper names of lakes and ponds, * oceanonyms: proper names of oceans, * pelagonyms: proper names of seas and maritime bays, * potamonyms: proper names of rivers and streams. Linguistic phenomena Often a given body of water will have several entirely different names given to it by different peoples living along its s ...

2007 United Kingdom Floods
A series of large floods occurred in parts of the United Kingdom during the summer of 2007. The worst of the flooding occurred across Scotland on 14 June; East Yorkshire and the Midlands on 15 June; Yorkshire, the Midlands, Gloucestershire, Herefordshire and Worcestershire on 25 June; and Gloucestershire, Herefordshire, Worcestershire, Oxfordshire, Berkshire and South Wales on 28 July 2007. June was one of the wettest months on record in Britain (see List of weather records). Average rainfall across the country was ; more than double the June average. Some areas received a month's worth of precipitation in 24 hours. It was Britain's wettest May–July period since records began in 1776. July had unusually unsettled weather and above-average rainfall through the month, peaking on 20 July as an active frontal system dumped more than of rain in southern England. Civil and military authorities described the June and July rescue efforts as the biggest in peacetime Britain. The Envi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Austropotamobius Pallipes
''Austropotamobius pallipes'' is an endangered European freshwater crayfish, and the only crayfish native to the British Isles. Its common names include white-clawed crayfish and Atlantic stream crayfish. Distribution It is found from the easterly Balkan Peninsula to Spain and reaches its northerly limit in Great Britain, as well as Ireland (where it is considered introduced), where it is limited to some regions only: its highest densities are in chalk streams. ''A. pallipes'' is the only crayfish found in Ireland, occurring over limestone areas in rivers, streams, canals, and lakes. In France, ''A. pallipes'' is found in streams such as the Mornante and Sellon, two small tributaries of the Dorlay in the Loire department. It is protected as a heritage species. It has also been introduced to Corsica, Liechtenstein, and Portugal (from where it is now extirpated). It was once found across most of Great Britain; however its distribution is rapidly shrinking, and it is record ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corallian Limestone
The Corallian Group or Corallian Limestone is a geologic group in England. It is predominantly a coralliferous sedimentary rock, laid down in the Oxfordian stage of the Jurassic. It is a hard variety of "coral rag". Building stones from this geological structure tend to be irregular in shape. It is often found close to seams of Portland Limestone (e.g. Abbotsbury in Dorset, England). It is a younger limestone than its near-neighbour, the Oolitic, as found in the Cotswolds, in Gloucestershire. It is laterally equivalent to and interfingers with units of the Ancholme Group. A ridge of Corallian Limestone rises above the Vale of Avon and the Thames Valley in its Oxfordshire stretch. The Oxfordshire Corallian ridge is an escarpment holding back the hanging valley that is the Vale of White Horse and its hardness forced the River Thames to take a wide northern detour, to cut through the low ridge at Oxford. High points along the ridge are Cumnor Hurst and Wytham Hill. The outcrop kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimmeridge Clay
The Kimmeridge Clay is a sedimentary deposit of fossiliferous marine clay which is of Late Jurassic to lowermost Cretaceous age and occurs in southern and eastern England and in the North Sea. This rock formation is the major source rock for North Sea oil. The fossil fauna of the Kimmeridge Clay includes turtles, crocodiles, sauropods, plesiosaurs, pliosaurs and ichthyosaurs, as well as a number of invertebrate species. Description Kimmeridge Clay is named after the village of Kimmeridge on the Dorset coast of England, where it is well exposed and forms part of the Jurassic Coast World Heritage Site. Onshore, it is of Late Jurassic ( Kimmeridgian) age and outcrops across England, in a band stretching from Dorset in the south-west, north-east to North Yorkshire. Offshore, it extends into the Lower Cretaceous (Berriasian Stage) and it is found throughout the Southern, Central and Northern North Sea. The foundations of the Humber Bridge on the southern (Barton) side of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gault
The Gault Formation is a geological formation of stiff blue clay deposited in a calm, fairly deep-water marine environment during the Lower Cretaceous Period (Upper and Middle Albian). It is well exposed in the coastal cliffs at Copt Point in Folkestone, Kent, England, where it overlays the Lower Greensand formation, and underlies the Upper Greensand Formation. These represent different facies, with the sandier parts probably being deposited close to the shore and the clay in quieter water further from the source of sediment; both are believed to be shallow-water deposits. The etymology of the name is uncertain and probably of local origin. Distribution It is found in exposure on the south side of the North Downs and the north side of the South Downs. It is also to be found beneath the scarp of the Berkshire Downs, in the Vale of White Horse, in Oxfordshire, England, and on the Isle of Wight where it is known as Blue Slipper. Gault underlies the chalk beneath the Londo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greensand
Greensand or green sand is a sand or sandstone which has a greenish color. This term is specifically applied to shallow marine sediment that contains noticeable quantities of rounded greenish grains. These grains are called ''glauconies'' and consist of a mixture of mixed-layer clay minerals, such as smectite and glauconite. Greensand is also loosely applied to any glauconitic sediment. Formation Greensand forms in anoxic marine environments that are rich in organic detritus and low in sedimentary input. Having accumulated in marine environments, greensands can be fossil-rich, such as in the late-Cretaceous deposits of New Jersey. Occurrence Important exposures are known from both northern and western Europe, North America, southeastern Brazil and north Africa. Well known and important greensands are the Upper and Lower Greensands of England and occur within Eocene and Cretaceous sedimentary strata underlying the coastal plains of New Jersey and Delaware. Although greensand ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and is the only boundary between geological periods to remain formally undefined. By the beginning of the Jurassi ...

Wilts & Berks Canal
The Wilts & Berks Canal is a canal in the historic counties of Wiltshire and Berkshire, England, linking the Kennet and Avon Canal at Semington near Melksham, to the River Thames at Abingdon. The North Wilts Canal merged with it to become a branch to the Thames and Severn Canal at Latton near Cricklade. Among professional trades boatmen, the canal was nicknamed the Ippey Cut, possibly short for Chippenham. The canal was opened in 1810, but abandoned in 1914 – a fate hastened by a breach at Stanley aqueduct in 1901. Much of the canal subsequently became unnavigable: many of the structures were deliberately damaged by army demolition exercises; parts of the route were filled in and in some cases built over. In 1977 the Wilts & Berks Canal Amenity Group was formed with a view to full restoration of the canal. Several locks and bridges have since been restored, and over of the canal have been rewatered. Name The official name of the canal is the "Wilts & Berks Canal" as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
