Rockall
Rockall () is a high, uninhabitable granite islet in the North Atlantic Ocean. It is west of Soay, St Kilda, Scotland; northwest of Tory Island, Ireland; and south of Iceland. The nearest permanently inhabited place is North Uist, east in Scotland's Outer Hebrides. Rockall was formed during the Paleogene period by magmatism, as part of the North Atlantic Igneous Province. Rockall's only named geographic location and occupiable area is Hall's Ledge. Rockall and Hasselwood Rock 200 metres North, are the only emergent parts of Helen's Reef and the Rockall Plateau. Rockall has appeared on maps since at least 1550 and in literature since at least 1698. Marine surveyors, scientists, adventurers, amateur radio operators and environmental activists, have variously landed on and/or briefly occupied the islet. The earliest documented landing on Rockall was in 1811 by a small Royal Navy party led by Basil Hall. The longest known continuous occupation is 45 days, achieved solo in ...

Rockall Plateau
The Rockall Trough () 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. ) sedimentary basin that lies beneath the trough. Both are named after Rockall, a rocky islet lying 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, Lorien Knoll, Isengard Ridge. In February 2000, the ' ...

Helen's Reef
Helen's Reef is a series of skerry, 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 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, but the dispute is resolved as of 31 March 2014. History Helen's Reef was named after the brigantine ''Helen'' of Dundee, bound for Quebec City, Quebec, which foundered at Hasselwood Rock in 1824. The vessel struck between nine and ten o'clock on the morning of 17 April. After some twelve hours struggling to keep her afloat and make for safety, water had almost filled the hold. The captain ordered the passengers onto the deck with warm clothing. Difficulty was experienced launching t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hasselwood Rock
Hasselwood Rock is a skerry 200 metres North of Rockall in the North Atlantic. Location and characteristics Hasselwood Rock is 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. Expeditions and landings on Hasselwood Rock have not been reported. 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. The upper part of Hasselwood Rock is the destroyed cone of an extinct volcano. 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 disa ...

Outer Hebrides
The Outer Hebrides ( ) or Western Isles ( , or ), sometimes known as the Long Isle or Long Island (), is an Archipelago, island chain off the west coast of mainland Scotland. It is the longest archipelago in the British Isles. The islands 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. The Outer Hebrides are considered to be the traditional heartland of the Gaelic language. The islands form one of the 32 council areas of Scotland, which since 1998 has used only the Gaelic form of its name, including in English language contexts. The council area is called Na h-Eileanan an Iar ('the Western Isles') and its council is ('Council of the Western Isles'). Most of the islands have a bedrock formed from ancient metamorphic rocks, and the climate is mild and oceanic. The 15 inhabited islands had a total population of in and there are more th ...

Basil Hall
Basil Hall (31 December 1788 – 11 September 1844) was a British naval officer from Scotland, a traveller, and an author. He was the second son of Sir James Hall, 4th Baronet, an eminent man of science. Early life Although his family home was at Dunglass, Haddingtonshire (now East Lothian), Basil Hall was born in George Square, Edinburgh, at his aunt's house. He was educated at the Royal High School and joined the Royal Navy in 1802, being commissioned a Lieutenant in 1808, and later rising to the rank of captain. Hall served aboard many vessels involved in exploration and scientific and diplomatic missions. From the beginning of his naval career he had been encouraged by his father to keep a journal, which later became the source for a series of books and publications describing his travels. Service in the Napoleonic Wars While serving aboard , Hall witnessed Sir John Moore being carried dying from the Battle of Corunna. It was also aboard the ''Endymion'' that Hall met ...

Islet
An islet ( ) is generally a small island. Definitions vary, and are not precise, but some suggest that an islet is a very small, often unnamed, island with little or no vegetation to 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 espe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Radiometric dating, Isotopic dating indicates the most active magmatic phase of the NAIP was bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territorial Sea
Territorial waters are informally an area of water where a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf (these components are sometimes collectively called the maritime zones). In a narrower sense, the term is often used as a synonym for the territorial sea. Vessels have different rights and duties when passing through each area defined by the United Nations Convention on the Law of the Sea (UNCLOS), one of the most ratified treaties. States cannot exercise their jurisdiction in waters beyond the exclusive economic zone, which are known as the high seas. Baseline Normally, the baseline is the low-water line along the coast as marked on large-scale charts that the coastal state recognizes. This is either the low-water mark closest to the shore or an unlimited distance from permanently exposed land, provided that some portion of elevations ...

Atlantic
The Atlantic Ocean is the second largest of the world's five oceanic divisions, with an area of about . It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soay, St Kilda
Soay () is an uninhabited islet in the St Kilda, Scotland, St Kilda archipelago, Scotland. The name is from Old Norse , meaning "island of sheep". The island is part of the St Kilda World Heritage Site and home to a primitive breed of sheep. Excluding Rockall, it is the westernmost point of the United Kingdom. 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 stack (geology), 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 summit, Cnoc Glas, is the most westerly hill in Great Britain and the United Kingdom. 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.
