Inisheer
Inisheer ( ga, Inis Oírr , or ) is the smallest and most easterly of the three Aran Islands in Galway Bay, Ireland. With 281 residents as of the 2016 census, it is second-most populous of the Arans. Caomhán of Inis Oírr is the island's patron saint. There are five small settlements: Baile Thiar, Chapeltown (Baile an tSéipéil), Castle Village (Baile an Chaisleáin), Baile an Fhormna and Baile an Lorgain. Name The island was originally called ''Árainn Airthir'', and later ''Inis Oirthir'', which are thought to mean "eastern Aran" and "eastern island" respectively. (see scanned records) The second element is also found in the names Inishsirrer and Orior. According to Séamas Ó Murchú, the current official name, , was brought into use by the Ordnance Survey Ireland. He says it may be a compromise between and the traditional local name . Geology and geography The island is geologically an extension of The Burren. The terrain of the island is composed of limeston ...

Caomhán Of Inisheer
Saint Caomhán (; may have died in 865), anglicised as Cavan, sometimes ''Kevin'', is the patron saint of Inisheer ( ga, Inis Oírr), the smallest of the Aran Islands. Although he is "by far the most celebrated of all the saints of the Aran Islands", little is known about him. He is said to have been a disciple of Saint Enda of Aran, which would place him in the 6th century, but his death date has also been recorded as 865.Mordecai Cubitt Cooke, John Eller Taylor, ''Hardwicke's Science-gossip'' Volumes 10–11 (1874)p. 272 The saint's Pattern Day ( ga, Lá an Phátrúin) was formerly 3 November, but was moved to 14 June in the 19th century. There used to be a pilgrimage of the sick to his tomb on his day, and an open-air mass is still celebrated there every year.Fionn Davenport, ''Ireland'', Lonely Planet (2010) p. 410. St Cavan's Church St Cavan's Church (also "St Kevin's Church", ga, Teampall Chaomhán) is a ruined church, built in the 10th century, at the location of the ...

Aran Islands
The Aran Islands ( ; gle, Oileáin Árann, ) or The Arans (''na hÁrainneacha'' ) are a group of three islands at the mouth of Galway Bay, off the west coast of Ireland, with a total area around . They constitute the historic barony of Aran in County Galway. From west to east, the islands are: Inishmore (''Árainn'' / ''Inis Mór''), which is the largest; Inishmaan (''Inis Meáin''), the second-largest; and Inisheer (''Inis Oírr''), the smallest. There are also several islets. The population of 1,226 (as of 2016) primarily speak Irish, the language of local placenames, making the islands a part of the Gaeltacht. Most islanders are also fluent or proficient in English. The population has steadily declined from around 3,500 in 1841. Location and access The approaches to the bay between the Aran Islands and the mainland are: * North Sound''An Súnda ó Thuaidh'' (more accurately ''Bealach Locha Lurgan'') lies between Inishmore and Lettermullen, County Galway. * Grego ...

Galway Bay
Galway Bay ( Irish: ''Loch Lurgain'' or ''Cuan na Gaillimhe'') is a bay on the west coast of Ireland, between County Galway in the province of Connacht to the north and the Burren in County Clare in the province of Munster to the south; Galway city is on the northeast side. The bay is about long and from to in breadth. The Aran Islands (''Oileáin Árann'') are to the west across the entrance and there are numerous small islands within the bay. To the west of Galway, the rocks are granite but to the south they are limestone. The approaches to the bay between the Aran Islands and the mainland are as follows: * the North Sound (''An Súnda ó Thuaidh'') lies between Inishmore and Leitir Mealláin in Connemara; known as ''Bealach Locha Lurgan'' in Irish. * Gregory's Sound (''Súnda Ghríoghóra'') lies between Inishmore and Inishmaan; known as ''Bealach na h-Áite'' in Irish. * Foul Sound (''An Súnda Salach'') lies between Inishmaan and Inisheer; known as ''Bealach na ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth#Surface, 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 Earth, the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North America, 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 8th paralle ...

Sea Urchin
Sea urchins () are spiny, globular echinoderms in the class Echinoidea. About 950 species of sea urchin live on the seabed of every ocean and inhabit every depth zone from the intertidal seashore down to . The spherical, hard shells (tests) of sea urchins are round and spiny, ranging in diameter from . Sea urchins move slowly, crawling with tube feet, and also propel themselves with their spines. Although algae are the primary diet, sea urchins also eat slow-moving ( sessile) animals. Predators that eat sea urchins include a wide variety of fish, starfish, crabs, marine mammals. Sea urchins are also used as food especially in Japan. Adult sea urchins have fivefold symmetry, but their pluteus larvae feature bilateral (mirror) symmetry, indicating that the sea urchin belongs to the Bilateria group of animal phyla, which also comprises the chordates and the arthropods, the annelids and the molluscs, and are found in every ocean and in every climate, from the tropics to t ...

Ammonites
Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) than they are to shelled nautiloids such as the living ''Nautilus'' species. The earliest ammonites appeared during the Devonian, with the last species vanishing during the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and linking the rock layer in which a particular species or genus is found to specific geologic time periods is often possible. Their fossil shells usually take the form of planispirals, although some helically spiraled and nonspiraled forms (known as heteromorphs) have been found. The name "ammonite", from which the scientific term is derived, was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams' horns.

Namurian
The Namurian is a stage in the regional stratigraphy of northwest Europe with an age between roughly 326 and 313 Ma (million years ago). It is a subdivision of the Carboniferous system or period and the regional Silesian series. The Namurian is named for the Belgian city and province of Namur where strata of this age occur (part of the Belgian Coal Measures). The Millstone Grit Group in the lithostratigraphy of northern England and parts of Wales is also of Namurian age. The Namurian age lasted from 326 to 313 million years ago. It is preceded by the Visean stage/age (which corresponds to the upper Carboniferous Limestone of Great Britain) and succeeded by the Westphalian stage/age (which corresponds to the lower and middle Coal Measures of Great Britain). In the official geologic timescale of the International Commission on Stratigraphy (ICS), the Namurian straddles the boundary between the Mississippian epoch (359-318 Ma) and the Pennsylvanian epoch (318-299 Ma).

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic
The Arctic ( or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada ( Yukon, Northwest Territories, Nunavut), Danish Realm ( Greenland), Finland, Iceland, Norway, Russia ( Murmansk, Siberia, Nenets Okrug, Novaya Zemlya), Sweden and the United States ( Alaska). Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. Definition and etymology The word Arctic comes from the Greek w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
