Iroise or the Iroise Sea ((フランス語:mer d'Iroise), or (:i.ʁwa)) is the part of the Atlantic Ocean which stretches from the Ile de Sein to Ushant off the coast of Brittany in north-western France. It borders the Celtic Sea to the north and west and the Bay of Biscay to the south. It is one of the most dangerous seas in Europe. In winter, there are often violent storms with huge waves. But it is also considered to be one of the richest areas for marine life leading to its inclusion as one of UNESCO's biosphere reserves in 1988 and as France's first marine park in October 2007.〔(Parc naturel marin d'Iroise - Official Site )〕 ==Name and extent== The name is first recorded in the ''Neptune francois'' of 1693 as ''Le Passage de l'Yroise'' (フランス語:''passage'' = "channel"); as Passage de l'Iroise in the 18th century; as Iroise in the 19th century; and as mer d'Iroise (フランス語:''mer'' = "sea") in the 1970s, by the seabed exploration industry.〔 〕 The name appears to have been fixed not by local seafarers but rather by the naval base at Brest.〔 The 18th-century maps restrict "Passage de l'Iroise" to the channel leading north-west from Pointe Saint-Mathieu and keeping south of Ushant and the Ponant Islands.〔 From the 19th century, ''Iroise'' encompasses all the sea the west coast of Brittany, between Ouessant and Sein.〔 While this remains the limit used by mariners, some twentieth-century sources have used ''mer d'Iroise'' to denote the entire Celtic Sea as far as Ireland and England.〔 The meaning of ''Iroise'' is obscure; theories include: * from the Old French ''Iroise'' meaning "Irish", denoting the route from France to Ireland〔 * from a dubious Old French adjective ''iroise'' meaning "angry", referring to the rough seas (sometimes ''Angry Sea'' is found as an English language translation) * from Breton ''hirgwaz''; ''hir'' "long" + ''gwaz'' "stream, channel"〔 * From the Breton ''ervoas'' "deep", referring to the Atlantic Ocean, in contrast to the shallow English Channel From the 1990s, "Iroise" became popular in Finistère in the name of many local businesses and associations.〔 The Pont de l'Iroise bridge was opened in 1994. 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「Iroise Sea」の詳細全文を読む スポンサード リンク
