Lairo Water
Lairo Water is a surface water body known as an ayre situated on the western coast of Shapinsay in the Orkney Islands. This brackish water body is separated by a narrow bar of land from Veantro Bay. This wetland is an area where a variety of bird species may be found. Hogan has suggested that the Lairo Water may have been a source of subsistence food for prehistoric inhabitants of Shapinsay at Burroughston Broch.

Ayre (landform)
An ayre is the name used for shingle beaches found in Orkney, Shetland, the Isle of Man, Lancashire, Cumbria and Northumbria. The word is derived from the Old Norse ''eyrr'', meaning a shingle beach or gravelly place, and may be applied to ordinary beaches, cliff-foot beaches such as the Lang Ayre in Northmavine, Shetland, spits, bars or tombolos, but only if formed of shingle. More than 130 such shingle beaches are named on Ordnance Survey maps of Shetland, but far fewer in Orkney, where most beaches are formed of sand. The word in its Old Norse form is common in Iceland, and it also occurs in a few place names in the north and west of the Scottish mainland which had a strong Norse influence, such as Eriboll ("a homestead on a shingle beach") and in the names of several shingle banks—Salt Ayre, Green Ayre, Stake Ayre, Rabbit Ayre and Whinny Ayre—in the tidal reach of the River Lune at Lancaster. Churchill Barrier number 4 in Orkney used a shingle spit, the Ayre of Cara on ... [...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 ...

Orkney Islands
Orkney (; sco, Orkney; on, Orkneyjar; nrn, Orknøjar), also known as the Orkney Islands, is an archipelago in the Northern Isles of Scotland, situated off the north coast of the island of Great Britain. Orkney is 10 miles (16 km) north of the coast of Caithness and has about 70 islands, of which 20 are inhabited. The largest island, the Mainland, has an area of , making it the sixth-largest Scottish island and the tenth-largest island in the British Isles. Orkney’s largest settlement, and also its administrative centre, is Kirkwall. Orkney is one of the 32 council areas of Scotland, as well as a constituency of the Scottish Parliament, a lieutenancy area, and an historic county. The local council is Orkney Islands Council, one of only three councils in Scotland with a majority of elected members who are independents. The islands have been inhabited for at least years, originally occupied by Mesolithic and Neolithic tribes and then by the Picts. Orkney was col ...

Brackish
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific grav ...

Veantro Bay
Veantro Bay is a bay on the northwest coast of Shapinsay in the Orkney Islands, Scotland. At the head of the bay is a large stone, thought to be associated with Viking settlement of Shapinsay, known as the Odin's Stone. It has been suggested that prehistoric man on Shapinsay, who inhabited Castle Bloody and Burroughston Broch, would have exploited the seafood resources of Lairo Water, an ayre at Veantro Bay. In 2005, the Orkney Community Councils opposed an application for a fish farm on Veantro Bay citing environmental concerns and competition with local fishermen A fisher or fisherman is someone who captures fish and other animals from a body of water, or gathers shellfish. Worldwide, there are about 38 million commercial and subsistence fishers and fish farmers. Fishers may be professional or recreat ....

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] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
