Firth is a word in the English and Scots languages used to denote various coastal waters in the United Kingdom, predominantly within Scotland. In the Northern Isles, it more usually refers to a smaller inlet. It is linguistically cognate to fjord which has a more constrained sense in English. Bodies of water named "firths" tend to be more common on the Scottish east coast, or in the southwest of the country, although the Firth of Clyde is an exception to this. The Highland coast contains numerous estuaries, straits, and inlets of a similar kind, but not called "firth" ; instead, these are often called sea lochs. Before about 1850, the spelling "Frith" was more common.
The Mainland, also known as Hrossey and Pomona, is the main island of Orkney, Scotland. Both of Orkney's burghs, Kirkwall and Stromness, lie on the island, which is also the heart of Orkney's ferry and air connections.
Stronsay is an island in Orkney, Scotland. It is known as Orkney's 'Island of Bays', owing to an irregular shape with miles of coastline, with three large bays separated by two isthmuses: St Catherine's Bay to the west, the Bay of Holland to the south and Mill Bay to the east. Stronsay is 3,275 hectares in area, and 44 metres in altitude at its highest point. It has a usually resident population of 349. The main village is Whitehall, home to a heritage centre.
Shapinsay 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.
Dunnet Head is a peninsula in Caithness, on the north coast of Scotland. Dunnet Head includes the most northerly point of both mainland Scotland and the island of Great Britain.
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.
Mill Dam is a wetland in western Shapinsay, in Orkney, Scotland.
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.
Mor Stein is a neolithic standing stone in the southeastern part of the island of Shapinsay, Orkney Islands, Scotland. Shapinsay is one of the two large inner islands of the Orkney group, and it is situated approximately two miles north of the Orkney Mainland. Linton Bay is situated slightly to the northeast of Mor Stein.
Waulkmill Bay is a tidal bay on the southwest of Mainland Orkney, Scotland. This bay and its immediately surrounding area have been identified as a Site of Special Scientific Interest by Scottish Natural Heritage.
The Bay of Linton is a bay on the east coast on the island of Shapinsay in the Orkney Islands, Scotland. To the north of Linton Bay are the headlands of Ness of Ork, and to the south is The Foot. The ancient monument the Broch of Burroughston is slightly north of Linton Bay.
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.
Castle Bloody is a prehistoric feature on the island of Shapinsay, Orkney, Scotland. Hogan observes that while the feature is marked as a chambered mound on the UK Ordnance Survey map, the structure is more properly and specifically classified as a souterrain or earth house. Slightly to the north is located the ruined historic Linton Chapel.
Linton Chapel is a ruined chapel on the east coast of Shapinsay, Orkney. The chapel is thought to date as early as the 12th century AD. Slightly to the south is a megalithic monument, Castle Bloody.
Quholm is a hamlet in the northeast of Shapinsay, in the islands of Orkney, Scotland. William Irving, the father of Washington Irving, noted American author, was born in Quholm. Innsker Beach is situated very close by at the northwest edge of Quholm. Slightly to the south along Shapinsay's northwest coast are located the coastal ayres of Lairo Water and the Ouse situated within Veantro Bay. There are significant archaeological sites not distant from Quholm, including Odin's Stone, Burroughston Broch, Linton Chapel, Castle Bloody and Mor Stein.
The Northern European Enclosure Dam (NEED) is a proposed solution to the problem of rising ocean levels in Northern Europe. It would be a megaproject, involving the construction of two massive dams in the English Channel and the North Sea; the former between France and England, and the latter between Scotland and Norway. The concept was conceived by the oceanographers Sjoerd Groeskamp and Joakim Kjellsson.
