Porcupine Bank is an area of the Irish shelf, on the fringes of the Atlantic Ocean approximately west of Ireland. The relatively raised area of seabed, 200 m below sea level at its highest,〔Shannon, P, Haughton, P, Corcoran D, (2001) The Petroleum Exploration of Ireland's Offshore Basins, Geological Society, P355〕 lies between the deep-water Porcupine Seabight and Rockall Trough. The name comes from the bank's discovery in 1862 by HMS ''Porcupine'', a British sail and paddle-wheel ship used mainly for surveying. The northern and western slopes of the bank feature species of cold-water corals.〔() Deepwater coral reefs found off west coast, RTÉ News, 26 May 2009〕 According to Dr. Anthony Grehan of the National University of Ireland, Galway, the virtually untouched site could benefit dwindling fish stocks and possibly aid medical research. In an 1870 paper presented to the Geological Society of Ireland, Mr W Fraser suggested that these reefs mark the site of the sunken island of Hy-Brasil. Hy-Brasil was recorded on maps of the 15th and 16th centuries and is sometimes referred to as the other Atlantis. == References == 〔 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「Porcupine Bank」の詳細全文を読む スポンサード リンク
