Mill Dam
Mill Dam is a wetland in western Shapinsay, in Orkney, Scotland. This water body was not shown on the 1840 survey map of the island, since it is a man-made creation from a damming in the 1880s.G.T, Masters, ''Orkney, Approaches to Kirkwall'', HMS official survey map, 1840-1843 Mill Dam is fed by a stream flowing from the north that rises on the western lobe of Shapinsay. The pH levels of the outflow stream of Mill Dam are moderately alkaline, in the range of 9.18. The Mill Dam wetland is a significant bird habitat and is owned and managed by the Royal Society for the Protection of Birds.

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shapinsay
Shapinsay (, sco, Shapinsee) is one of the Orkney Islands off the north coast of mainland Scotland. There is one village on the island, Balfour, from which roll-on/roll-off car ferries sail to Kirkwall on the Orkney Mainland. Balfour Castle, built in the Scottish Baronial style, is one of the island's most prominent features, a reminder of the Balfour family's domination of Shapinsay during the 18th and 19th centuries; the Balfours transformed life on the island by introducing new agricultural techniques. Other landmarks include a standing stone, an Iron Age broch, a souterrain and a salt-water shower. With an area of , Shapinsay is the eighth largest island in the Orkney archipelago. It is low-lying and fertile, consequently most of the area is given over to farming. Shapinsay has two nature reserves and is notable for its bird life. At the 2011 census, Shapinsay had a population of 307. The economy of the island is primarily based on agriculture with the exception of a fe ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Alkaline
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a base (chemistry), basic, ionic compound, ionic salt (chemistry), salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English language, English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the acid-base reaction theories#Arrhenius theory, Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Society For The Protection Of Birds
The Royal Society for the Protection of Birds (RSPB) is a charitable organisation registered in England and Wales and in Scotland. It was founded in 1889. It works to promote conservation and protection of birds and the wider environment through public awareness campaigns, petitions and through the operation of nature reserves throughout the United Kingdom. In 2020/21 the RSPB had an income of £117 million, 2,000 employees, 12,000 volunteers and 1.1 million members (including 195,000 youth members), making it one of the world's largest wildlife conservation organisations. The RSPB has many local groups and maintains 222 nature reserves. As founders, chief officers and presidents, women have been at the helm of the RSPB for over 85 years. History The origins of the RSPB lie with two groups of women, both formed in 1889: * The Plumage League was founded by Emily Williamson at her house in Didsbury, Manchester, as a protest group campaigning against the use of great crested ...

Balfour Castle
Balfour Castle is a historic building on the southwest of Shapinsay, Orkney Islands. Though built around an older structure that dates at least from the 18th century, the present castle was built in 1847, commissioned by Colonel David Balfour, and designed by Edinburgh architect David Bryce. It is a Category A listed building and the landscape and formal gardens are listed in the Inventory of Gardens and Designed Landscapes in Scotland. As of 2021, the castle was operating as a hotel. Prehistory The small island of Shapinsay has been inhabited since prehistoric times, the most notable evidence being the extant Broch of Burroughston, located not far from Balfour Castle to the northeast;C. Michael Hogan. 2007 moreover, the Mor Stein standing stone dating to the stone age is found also to the east of Balfour Castle, evidencing even earlier presence of man in the vicinity.

Burroughston Broch
Burroughston Broch is an Iron Age broch located on the island of Shapinsay in the Orkney Islands, in Scotland (). The site overlooks the North Sea on the northeast part of Shapinsay. Excavated in the mid 19th century, Burroughston Broch is still well-preserved. The drystone walls are up to four metres thick in some parts and there is a complete chamber intact off the entrance passage. Some remains of stone fittings are evident in the interior. Location Burroughston Broch overlooks the North Sea at the northeast corner of Shapinsay island, about 4 miles from the ferry pier. Slightly to the south lies Linton Bay. The broch stands at the foot of a gently sloping field just above the low rocky shoreline. It is one of the best preserved brochs in Orkney. Description The walls of Burroughston Broch have an external diameter of around 18 metres, and an internal diameter of around 10 metres. From the outside, the building appears as a grassy mound, and little of the outer wall is exposed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Ouse
The Ouse is a tidal estuary in northern Shapinsay, Orkney Islands. This water body has been shown on early maps of the island in a very similar shape to its current geometry. The Ouse is fed by small rivulets and upland springs that rise on the western part of the island's northeast spur. pH levels of these feed waters are moderately alkaline, in the range of 9.1.C.M Hogan, ''Natural History of the Orkney Islands'' (2006) See also *Burroughston Broch *Mor Stein *Vasa Loch Vasa Loch is a brackish lagoon in southwestern Shapinsay, Orkney Islands.

Vasa Loch
Vasa Loch is a brackish lagoon in southwestern Shapinsay, Orkney Islands. (Ordnance, 2002) This water body has been shown on early maps of the island in a very similar shape and size to its current geometry, separated from the North Sea by a narrow strip of raised beach.(Masters, 1840) Vasa Loch is fed by small rivulets and upland springs that rise on the western part of the island's western spur. pH levels of the loch are strongly alkaline, in the range of 10.15. (Hogan, 2006) Geology The particular landform associated with Vasa Loch is an ''ayre'', derived from the Old Norse word used to depict a lake which is only separated by a narrow strip of low-lying land from the sea itself.(Shapinsay) Notes *Ordnance Survey Map, Landranger, United Kingdom, 1:50,000 (2002) * G.T, Masters, ''Orkney, Approaches to Kirkwall'', HMS official survey map, 1840-1843 *C.M Hogan, ''Natural History of the Orkney Islands'' (2006)Shapinsay Island, Orkney See also *Balfour Castle *Burroughston Broch ...

Dams In Scotland
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
