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 Canal 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 ...

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 ...

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. 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. Fresh water ...

Dumfries And Galloway Council
Dumfries and Galloway ( sco, Dumfries an Gallowa; gd, Dùn Phrìs is Gall-Ghaidhealaibh) is one of 32 unitary council areas of Scotland and is located in the western Southern Uplands. It covers the historic counties of Dumfriesshire, Kirkcudbrightshire, and Wigtownshire, the latter two of which are collectively known as Galloway. The administrative centre and largest settlement is the town of Dumfries. The second largest town is Stranraer, on the North Channel coast, some to the west of Dumfries. Following the 1975 reorganisation of local government in Scotland, the three counties were joined to form a single region of Dumfries and Galloway, 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 lieutenancy areas called Dumfries, Wigtown and the Stewartry of Kirkcudbright, broadly corresponding to the three historic counties.

South West Scotland Environmental Action Trust
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both east and west. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same 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', cf English meridional), 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). Navigation By convention, the ''bottom or down-facing side'' of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeration
Aeration (also called aerification or aeriation) is the Systems engineering process, process by which air is circulated through, mixed with or solvation, 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 Turbine, 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 turbu ...

Marl
Marl is an earthy material rich in carbonate minerals, clays, and silt. When 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 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-rich mud or mudstone which contains variable amounts of 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 freshwater conditions. These typically contain 35–65% clay and 65–35% carbonate. The te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loch
''Loch'' () is the Scottish Gaelic, Scots language, Scots and Irish language, Irish word for a lake or sea inlet. It is Cognate, cognate with the Manx language, Manx lough, Cornish language, Cornish logh, and one of the Welsh language, Welsh words for lake, llwch. In English English and Hiberno-English, the Anglicisation, anglicised spelling lough is commonly found in place names; in Lowland Scots and Scottish English, the spelling "loch" is always used. Many loughs are connected to stories of lake-bursts, signifying their mythical origin. Sea-inlet lochs are often called sea lochs or sea loughs. Some such bodies of water could also be called firths, fjords, estuary, estuaries, straits or bays. 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, Iri ...

River Dee, Galloway
The River Dee ( gd, Dè / Uisge Dhè), 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 Dee has also been known as the ...

Crannog
A crannog (; ga, crannóg ; gd, crannag ) is typically a partially or entirely artificial island, usually built in lakes and estuarine waters of Scotland, Wales, and Ireland. Unlike the prehistoric pile dwellings around the Alps, which were built on the shores and not inundated until later, crannogs were built in the water, thus forming artificial islands. Crannogs were used as dwellings over five millennia, from the European Neolithic Period to as late as the 17th/early 18th century. In Scotland there is no convincing evidence in the archaeological record of Early and Middle Bronze Age or Norse Period use. 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 Early Iron Age. The date ranges fall ''after'' around 800 BC and so could be considered Late Bronze Age by only the narrowest of margins. Crannogs have been variously interpreted as free-standing wooden struct ...
