Pen Park Hole
Pen Park Hole is a large cavern situated underground, at the edge of Filton Golf Course. The cavern was discovered accidentally in the 17th Century and the first descent was made by Captain Sturmy in 1669. The entrance is adjacent to the Southmead and Brentry housing estates of north Bristol. Access is tightly controlled by Bristol City Council. It was scheduled as a Site of Special Scientific Interest in 2016 on account of its geological origins, and its cave invertebrate community including the cave shrimp '' Niphargus kochianus'', which is normally known as a spring seepage or chalk aquifer species. History Captain Sturmy descended into the pit on July 2, 1669. Having roped down from an old lead mine, he and a miner companion descended using 25 fathoms () of rope. They found a large chamber which they illuminated with candles. Exploring further they found an underground river 20 fathoms wide. Seeing a passage above them, they had a ladder lowered which they used to ascend i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southmead
Southmead is a northern suburb and council ward of Bristol, in the south west of England, bordered by Filton in South Gloucestershire and Monks Park, Horfield, Henleaze and Westbury on Trym. The River Trym rises in Southmead and flows south west through Badock's Wood, a Local Nature Reserve. There is a round barrow near the northern end of the wood, and a Site of Special Scientific Interest, Pen Park Hole. History Southmead was a manor of the parish of Westbury on Trym. The manor house, mentioned in a document of 1319, was near the south end of what is now Southmead Road. Most of the estate of was sold in the late 19th century. By 1888 Southmead was a small hamlet on Southmead Road. Southmead Hospital, formerly the Barton Regis Workhouse, was opened there in 1924. Large-scale development of the area started in 1931, when the Bristol Corporation built 1,500 houses to the north of Southmead Road, partly to house families cleared from the slums of central Bristol, and partly to ...

Bristol
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetia ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bristol City Council
Bristol City Council is the local authority of Bristol, England. The council is a unitary authority, and is unusual in the United Kingdom in that its executive function is controlled by a directly elected mayor of Bristol. Bristol has 34 wards, electing a total of 70 councillors. History The council was formed by the Local Government Act 1972. It was first elected in 1973, a year before formally coming into its powers and prior to the creation of the non-metropolitan district of Bristol on 1 April 1974. Under the Local Government Act 1972 Bristol as a non-metropolitan district council would share power with the Avon County Council. This arrangement lasted until 1996 when Avon County Council was abolished and Bristol City Council gained responsibility for services that had been provided by the county council. Political composition Mayor The mayor of Bristol following the 2021 mayoral election is Marvin Rees for the Labour Party. Originally intended to serve for four yea ...

Filton
Filton is a town and civil parish in South Gloucestershire, England, north of Bristol. Along with nearby Patchway and Bradley Stoke, Filton forms part of the Bristol urban area and has become an overflow settlement for the city. Filton Church dates back to the 12th century and is designated a Grade II listed building. The name of the town comes from the Old English language, Old English ''feleþe'' (hay), and ''tūn'' (farm, field). The name dates back to at least 1187. Filton has large areas of open space which include several playing fields, a golf course and the former Filton Airport (closed in 2012). Connections, districts and facilities Filton can be reached from Junction 1 of the M32 motorway, or from Junction 16 of the M5 motorway.

Brentry
Brentry is a suburb of north Bristol, England, between Henbury and Southmead which is spread along the southern edge of the Filton to Avonmouth railway line. Description The boundaries of Brentry are not well defined. The settlement grew around the junction of two roads, where a public house, the Old Crow, has long been established. The north-south road, Passage Road (now the A4018), was a turnpike road from Bristol to South Wales via New Passage or the Old Passage at Aust Ferry. When the new Filton By-Pass (now part of the M5 motorway) was opened in 1962, the route became an arterial road linking the new road to the centre of Bristol. The east-west route (B4057) is now of only local importance, but in the 1930s it carried A38 traffic by-passing Bristol. The through route was cut by the runway for the giant Bristol Brabazon aircraft built in 1949. The area east of the junction was developed in the 20th century, and Brentry is now sometimes considered to extend as far as the ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Niphargus Kochianus
''Niphargus'' is by far the largest genus of its family, the Niphargidae, and the largest of all freshwater amphipod genera. Usually, these animals inhabit caves or groundwater. They occur in western Eurasia, in regions that were not covered by the Pleistocene ice sheets. They are found throughout most of Europe with the notable exception of the Nordics and they are also largely missing from Iberia. The genus extends into Asia as far as the Arabian Peninsula and Iran. In their main range – the central Mediterranean region through Central and Eastern Europe to the Ukraine – they are among the most significant organisms inhabiting the groundwater. In the Dinaric Alps alone there are at least 45 species. There are also six species in the British Isles (the northernmost ''Niphargus''): ''N. aquilex'', ''N. fontanus'', ''N. glenniei'' and ''N. kochianus'' of Great Britain, and ''N. irlandicus'' and ''N. wexfordensis'' of Ireland. Although the individual species often ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fathom
A fathom is a unit of length in the imperial and the U.S. customary systems equal to , used especially for measuring the depth of water. The fathom is neither an International Standard (SI) unit, nor an internationally-accepted non-SI unit. Historically, however, it is the most frequently employed maritime measure of depth in the English-speaking world. There are two yards (6 feet) in an imperial fathom. Originally the span of a man's outstretched arms, the size of a fathom has varied slightly depending on whether it was defined as a thousandth of an (Admiralty) nautical mile or as a multiple of the imperial yard. Formerly, the term was used for any of several units of length varying around . Name The name (pronounced ) derives from the Old English word ''fæðm'', cognate to the Danish (via the Vikings) word "favn" meaning embracing arms or a pair of outstretched arms. Cognate maybe also via the Old High German word "fadum" of the same meaning.''Oxford English Dictionary' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Mary Redcliffe
St Mary Redcliffe is an Anglican parish church located in the Redcliffe district of Bristol, England. The church is a short walk from Bristol Temple Meads station. The church building was constructed from the 12th to the 15th centuries, and it has been a place of Christian worship for over 900 years. The church is renowned for the beauty of its Gothic architecture and is classed as a Grade I listed building by Historic England. It was famously described by Queen Elizabeth I as "the fairest, goodliest, and most famous parish church in England." Little remains of the earliest churches on the site although a little of the fabric has been dated to the 12th century. Much of the current building dates from the late 13th and 14th centuries when it was built and decorated by wealthy merchants of the city whose tomb and monuments decorate the church. The spire fell after being struck by lightning in 1446 and was not rebuilt until 1872. Little of the original stained glass remains follow ...

Sounding Line
Depth sounding, often simply called sounding, is measuring the depth of a body of water. Data taken from soundings are used in bathymetry to make maps of the floor of a body of water, such as the seabed topography. Soundings were traditionally shown on nautical charts in fathoms and feet. The National Oceanic and Atmospheric Administration (NOAA), the agency responsible for bathymetric data in the United States, still uses fathoms and feet on nautical charts. In other countries, the International System of Units (metres) has become the standard for measuring depth. Terminology "Sounding" derives from the Old English ''sund'', meaning "swimming, water, sea"; it is not related to the word ''sound'' in the sense of noise or tones, but to ''sound'', a geographical term. Traditional terms for soundings are a source for common expressions in the English language, notably "deep six" (a sounding of 6 fathoms). On the Mississippi River in the 1850s, the leadsmen also used old-fashione ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
