Rockall
Rockall () is an uninhabitable granite islet situated in the North Atlantic Ocean. The United Kingdom claims that Rockall lies within its exclusive economic zone (EEZ) and is part of its territory, but this claim is not recognised by Ireland. It and the nearby skerries of Hasselwood Rock and Helen's Reef are the only emergent parts of the Rockall Plateau. The rock was formed by magmatism as part of the North Atlantic Igneous Province during the Paleogene. Rockall's approximate distances from the closest islands in each direction are as follows: It is west of Soay, Scotland; northwest of Tory Island, Ireland; and south of Iceland. The nearest permanently inhabited place is North Uist, an island in the Outer Hebrides of Scotland, to the east. The United Kingdom claimed Rockall in 1955 and incorporated it as a part of Scotland in 1972. The UK does not make a claim to extended EEZ based on Rockall, as it has ratified the United Nations Convention on the Law of the Sea (UNCLOS ...

Rockall Plateau
The Rockall Trough ( gd, Clais Sgeir Rocail) is a deep-water bathymetric feature to the northwest of Scotland and Ireland, running roughly from southwest to northeast, flanked on the north by the Rockall Plateau and to the south by the Porcupine Seabight. At the northern end, the channel is bounded by the Wyville-Thomson Ridge, named after Charles Wyville Thomson, professor of zoology at the University of Edinburgh and driving force behind the Challenger Expedition. At the southern end, the trough opens into the Porcupine abyssal plain. The Rockall Basin (also known as the Hatton Rockall Basin) is a large (c. 800 km by 150 km) sedimentary basin that lies beneath the trough. Both are named after Rockall, a rocky islet lying 301.4 km west of St Kilda. Features of the Rockall Plateau have been officially named after features of Middle-earth in the fiction of J. R. R. Tolkien, e.g. Eriador Seamount, Rohan Seamount, Gondor Seamount, Fangorn Bank, Edoras Bank, Lor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helen's Reef
Helen's Reef is a series of skerries in the North Atlantic, northeast of the larger islet of Rockall and outcrop of Hasselwood Rock, within the United Kingdom's exclusive economic zone. The skerries are covered at high tide or in rough seas, and are often only visible as breaking waves. It is within the radius territorial waters of Rockall, which is claimed by the UK as of 1955 and incorporated into the UK by the Island of Rockall Act 1972. This claim was previously long disputed by Ireland,Written Answers - Rockall Island ''debates.oireachtas.ie'' 24 March 2011. Retrieved 6 April 2014.

Hasselwood Rock
Hasselwood Rock is a skerry adjacent to Rockall in the North Atlantic. Position and characteristics The upper part of Hasselwood Rock is the destroyed cone of an extinct volcano, some north of the larger outcrop of Rockall.G. S. Holland and R. A.GardinerThe First Map of Rockall. The Geographical Journal, v.141, n.1 (March 1975). pp. 94-98. The rock is approximately above low water, and in diameter, with an area of approximately . It is covered at high tide and in heavy seas, often only visible as breaking waves. The only other rocks in the area, those of Helen's Reef, are almost to the north-east. Expeditions and landings have not been reported. The geological composition is unknown. SS ''Norge'' disaster In 1904, the SS ''Norge'' ran aground on the Rock in foggy weather with the loss of over 635 lives. The sinking remains the worst maritime disaster involving a Danish merchant ship, and was at the time the worst civilian disaster in the Atlantic Ocean until the sinking of ...

Outer Hebrides
The Outer Hebrides () or Western Isles ( gd, Na h-Eileanan Siar or or ("islands of the strangers"); sco, Waster Isles), sometimes known as the Long Isle/Long Island ( gd, An t-Eilean Fada, links=no), is an island chain off the west coast of mainland Scotland. The islands are geographically coextensive with , one of the 32 unitary council areas of Scotland. They form part of the archipelago of the Hebrides, separated from the Scottish mainland and from the Inner Hebrides by the waters of the Minch, the Little Minch, and the Sea of the Hebrides. Scottish Gaelic is the predominant spoken language, although in a few areas English speakers form a majority. Most of the islands have a bedrock formed from ancient metamorphic rocks, and the climate is mild and oceanic. The 15 inhabited islands have a total population of and there are more than 50 substantial uninhabited islands. The distance from Barra Head to the Butt of Lewis is roughly .

Islet
An islet is a very small, often unnamed island. Most definitions are not precise, but some suggest that an islet has little or no vegetation and cannot support human habitation. It may be made of rock, sand and/or hard coral; may be permanent or tidal (i.e. surfaced reef or seamount); and may exist in the sea, lakes, rivers or any other sizeable bodies of water. Definition As suggested by its origin ''islette'', an Old French diminutive of "isle", use of the term implies small size, but little attention is given to drawing an upper limit on its applicability. The World Landforms website says, "An islet landform is generally considered to be a rock or small island that has little vegetation and cannot sustain human habitation", and further that size may vary from a few square feet to several square miles, with no specific rule pertaining to size. Other terms * Ait (/eɪt/, like eight) or eyot (/aɪ(ə)t, eɪt/), a small island. It is especially used to refer to river i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Territorial Sea
The term territorial waters is sometimes used informally to refer to any area of water over which a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf. In a narrower sense, the term is used as a synonym for the territorial sea. Baseline Normally, the baseline from which the territorial sea is measured is the low-water line along the coast as marked on large-scale charts officially recognized by the coastal state. This is either the low-water mark closest to the shore, or alternatively it may be an unlimited distance from permanently exposed land, provided that some portion of elevations exposed at low tide but covered at high tide (like mud flats) is within of permanently exposed land. Straight baselines can alternatively be defined connecting fringing islands along a coast, across the mouths of rivers, or with certain restrictions across the mou ...

North Atlantic Igneous Province
The North Atlantic Igneous Province (NAIP) is a large igneous province in the North Atlantic, centered on Iceland. In the Paleogene, the province formed the Thulean Plateau, a large basaltic lava plain, which extended over at least in area and in volume. The plateau was broken up during the opening of the North Atlantic Ocean leaving remnants preserved in north Ireland, west Scotland, the Faroe Islands, northwest Iceland, east Greenland, western Norway and many of the islands located in the north eastern portion of the North Atlantic Ocean. The igneous province is the origin of the Giant's Causeway and Fingal's Cave. The province is also known as Brito–Arctic province (also known as the North Atlantic Tertiary Volcanic Province) and the portion of the province in the British Isles is also called the British Tertiary Volcanic Province or British Tertiary Igneous Province. Formation Isotopic dating indicates the most active magmatic phase of the NAIP was between and c. 54.5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Kilda, Scotland
St Kilda ( gd, Hiort) is an isolated archipelago situated west-northwest of North Uist in the North Atlantic Ocean. It contains the westernmost islands of the Outer Hebrides of Scotland. The largest island is Hirta, whose sea cliffs are the highest in the United Kingdom; three other islands ( Dùn, Soay and Boreray) were also used for grazing and seabird hunting. The islands are administratively a part of the Comhairle nan Eilean Siar local authority area. The origin of the name ''St Kilda'' is a matter of conjecture. The islands' human heritage includes numerous unique architectural features from the historic and prehistoric periods, although the earliest written records of island life date from the Late Middle Ages. The medieval village on Hirta was rebuilt in the 19th century, but illnesses brought by increased external contacts through tourism, and the upheaval of the First World War contributed to the island's evacuation in 1930. The story of St Kilda has attracted artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soay, St Kilda
Soay ( gd, Soaigh) is an uninhabited islet in the St Kilda archipelago, Scotland. The name is from Old Norse ''Seyðoy'', meaning "Island of Sheep". The island is part of the St Kilda World Heritage Site and home to a primitive breed of sheep. It is the westernmost point in the United Kingdom if disputed Rockall is excluded. Geography Soay lies some west-northwest of North Uist in the North Atlantic It is about north-west of Hirta, from which it is separated by the narrow Sound of Soay, which is only about 500 metres wide. Two sea stacks, Stac Shoaigh (Soay Stac), , and Stac Biorach, , lie between. The island covers about and reaches a height of , the cliffs rising sheer from the sea. The island is formed of a breccia of gabbro and dolerites and is a single mountain peak rising from the sea-bed, without Ice-Age erosion. Along with the rest of the archipelago, Soay is owned by the National Trust for Scotland, managed by NatureScot as a nature reserve and is included it t ...

Martin Martin
Martin Martin (Scottish Gaelic: Màrtainn MacGilleMhàrtainn) (-9 October 1718) was a Scottish writer best known for his work '' A Description of the Western Islands of Scotland'' (1703; second edition 1716). This book is particularly noted for its information on the St Kilda archipelago. Martin's description of St Kilda, which he visited in 1697, had also been published some years earlier as ''A Late Voyage to St Kilda'' (1698). Life Martin was a native of Bealach, near Duntulm on Skye and he was born around 1660. He was a son of Donald Martin, who served with the MacDonalds of Sleat under James Graham, 1st Marquess of Montrose, and his wife Màiri, who was a niece of Dòmhnall Gorm Òg MacDonald, 1st Baronet of Sleat.
