The Celtic Sea ((アイルランド語:An Mhuir Cheilteach); (ウェールズ語:Y Môr Celtaidd); (コーンウォール語:An Mor Keltek); (ブルトン語:Ar Mor Keltiek); ) is the area of the Atlantic Ocean off the south coast of Ireland bounded to the east by Saint George's Channel;〔C.Michael Hogan. 2011. (''Celtic Sea''. eds. P.saundry & C.Cleveland. Encyclopedia of Earth. National Council for Science and the /environment. Washington DC. )〕 other limits include the Bristol Channel, the English Channel, and the Bay of Biscay, as well as adjacent portions of Wales, Cornwall, Devon, and Brittany. The southern and western boundaries are delimited by the continental shelf, which drops away sharply. ==History== The Celtic Sea takes its name from the Celtic heritage of the bounding lands to the north and east.〔 〕 The name was first proposed by E.W.L. Holt at a 1921 meeting in Dublin of fisheries experts from England, Ireland, Scotland and France.〔 The northern portion of this sea had previously been considered as part of Saint George's Channel and the southern portion as an undifferentiated part of the "Southwest Approaches" to Britain. The need for a common name came to be felt because of the common marine biology, geology and hydrology.〔 It was adopted in France before being common in the English-speaking countries.〔 It was adopted by marine biologists and oceanographers, and later by petroleum exploration firms.〔 〕 It is named in a 1963 British atlas,〔; cited in 〕 but a 1972 article states "what British maps call the Western Approaches, and what the oil industry calls the Celtic Sea () certainly the residents on the western coast (Great Britain ) don't refer to it as such."〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Celtic Sea」の詳細全文を読む スポンサード リンク
