Carlingwark Loch
Carlingwark Loch is a small freshwater loch in the historical county of Kirkcudbrightshire, Dumfries and Galloway, Scotland lying just south of Castle Douglas and is roughly rectangular in shape, trending nearly north and south. The name of the loch comes from the Scots Gaelic word Caer meaning fort and wark the old Scots language word for work. There are four artificial islets in the loch showing evidence of fortification and settlement, Ash Island is thought to be a crannog. Several archaeological finds have been retrieved from the loch including a bronze cauldron, sword and pan and two dugout canoes. Carlingwark Lane is a 1.5 mile canal which opened between the loch and the River Dee, 1.5 miles away in 1765. It remained in use until its abandonment in about 1840, allowing flat-bottomed boats to transport shell-marl to farms along the route. There is a footpath around the loch and it is popular for bird watching and fishing. As of 5 March 2012 the loch and the land aroun ...

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 reserve (United Kingdom), national nature reserves, Ramsar Convention, Ramsar sites, Special Protection Areas, and Special Area of Conservation, Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their Biology, biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or Physical geography, physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Lochs Of Scotland
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but 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. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumfries And Galloway Council
Dumfries and Galloway (; ) is one of the 32 unitary council areas of Scotland, located in the western part of the Southern Uplands. It is bordered by East Ayrshire, South Ayrshire, and South Lanarkshire to the north; Scottish Borders to the north-east; the English county of Cumbria, the Solway Firth, and the Irish Sea to the south, and the North Channel to the west. The administrative centre and largest settlement is the town of Dumfries. The second largest town is Stranraer, located to the west of Dumfries on the North Channel coast. Dumfries and Galloway corresponds to the historic shires of Dumfriesshire, Kirkcudbrightshire, and Wigtownshire, the last two of which are collectively known as Galloway. The three counties were combined in 1975 to form a single region, with four districts within it. The districts were abolished in 1996, since when Dumfries and Galloway has been a unitary local authority. For lieutenancy purposes, the area is divided into three lieutenanc ...

South West Scotland Environmental Action Trust
South is one of the cardinal directions or Points of the compass, compass points. The direction is the opposite of north and is perpendicular to both west and east. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic language, Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European language, Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', ), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant).

Cyanobacteria
Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteria's informal common name, blue-green algae. Cyanobacteria are probably the most numerous taxon to have ever existed on Earth and the first organisms known to have produced oxygen, having appeared in the middle Archean eon and apparently originated in a freshwater or terrestrial environment. Their photopigments can absorb the red- and blue-spectrum frequencies of sunlight (thus reflecting a greenish color) to split water molecules into hydrogen ions and oxygen. The hydrogen ions are used to react with carbon dioxide to produce complex organic compounds such as carbohydrates (a process known as carbon fixation), and the oxygen is released as a byproduct. By continuously producing and releasing oxygen over billions of years, cyanobacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeration
Aeration (also called aerification or aeriation) is the process by which air is circulated through, mixed with or dissolved in a liquid or other substances that act as a fluid (such as soil). Aeration processes create additional surface area in the mixture, allowing greater chemical or suspension reactions. Aeration of liquids Methods Aeration of liquids (usually water) is achieved by: * passing air through the liquid by means of the Venturi tube, aeration turbines or compressed air which can be combined with diffuser(s) air stone(s), as well as fine bubble diffusers, coarse bubble diffusers or linear aeration tubing. Ceramics are suitable for this purpose, often involving dispersion of fine air or gas bubbles through the porous ceramic into a liquid. The smaller the bubbles, the more gas is exposed to the liquid increasing the gas transfer efficiency. Diffusers or spargers can also be designed into the system to cause turbulence or mixing if desired. Porous ceramic diffusers ...

Marl
Marl is an earthy material rich in carbonate minerals, Clay minerals, clays, and silt. When Lithification, hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae. Marl makes up the lower part of the White cliffs of Dover, cliffs of Dover, and the Channel Tunnel follows these marl layers between France and the United Kingdom. Marl is also a common sediment in post-glacial lakes, such as the marl ponds of the northeastern United States. Marl has been used as a soil conditioner and neutralizing agent for acid soil and in the manufacture of cement. Description Marl or marlstone is a carbonate mineral, carbonate-rich mud or mudstone which contains variable amounts of Clay minerals, clays and silt. The term was originally loosely applied to a variety of materials, most of which occur as loose, earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwa ...

Loch
''Loch'' ( ) is a word meaning "lake" or "inlet, sea inlet" in Scottish Gaelic, Scottish and Irish Gaelic, subsequently borrowed into English. In Irish contexts, it often appears in the anglicized form "lough". A small loch is sometimes called a lochan. Lochs which connect to the sea may be called "sea lochs" or "sea loughs". Background This name for a body of water is Insular Celtic languages, Insular CelticThe current form has currency in the following languages: Scottish Gaelic, Irish language, Irish, Manx language, Manx, and has been borrowed into Scots language, Lowland Scots, Scottish English, Irish English and Standard English. in origin and is applied to most lakes in Scotland and to many sea inlets in the west and north of Scotland. Many of the loughs in Northern England have also previously been called "meres" (a Northern English dialect word for "lake", and an archaic Standard English word meaning "a lake that is broad in relation to its depth"), similar to th ...

River Dee, Galloway
The River Dee (), in south-west Scotland, flows from its source in Loch Dee amongst the Galloway Hills, firstly to Clatteringshaws Loch, then into Loch Ken, where it joins the Water of Ken. From there, the Dee flows southwards to Kirkcudbright, and into Kirkcudbright Bay to reach the Solway Firth. The distance is just over in total. Together with its tributaries, the Dee's total catchment area is over . The river is dammed at Tongland, two miles (3 km) upriver from Kirkcudbright. This was constructed as part of the Galloway hydro-electric power scheme in the 1930s. Also at this site is Tongland Bridge, built in 1806 by Thomas Telford. The ruins of Threave Castle stand on an island on the lower part of the Dee. In Ptolemy's 2nd century work ''Geography'' it is recorded as ''Dēoúa''. This form represents a development of Proto-Indo-European'' *deiueh2-'' 'a goddess', which occurs in many Celtic river-names. The Battle of the River Dee may have been fought ...

Crannog
A crannog (; ; ) is typically a partially or entirely artificial island, usually constructed in lakes, bogs and estuary, estuarine waters of Ireland, Scotland, and Wales. Unlike the prehistoric pile dwellings around the Alps, which were built on shores and not inundated until later, crannogs were built in the water, thus forming artificial islands. Humans have inhabited crannogs over five millennia, from the Neolithic#Europe, European Neolithic Period to as late as the 17th/early-18th centuries. In Scotland there is no convincing evidence in the archaeological record of their use in the Early or Middle Bronze Age Britain, Bronze Age or in the Scandinavian Scotland, Norse period. The radiocarbon dating obtained from key sites such as Oakbank and Redcastle indicates at a 95.4 per cent confidence level that they date to the Late Bronze Age to Iron Age Britain, Early Iron Age. The date ranges fall ''after'' around 800 BC and so could be considered Late Bronze Age by only the narrow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
