The Irish Sea ((アイルランド語:Muir Éireann),〔(Focal.ie )〕 (マン島語:Y Keayn Yernagh), , (スコットランド・ゲール語:Muir Èireann),〔Cambridge Medieval Celtic Studies , Issues 33–35 University of Cambridge (Gran Bretaña). Department of Anglo-Saxon, Norse and Celtic 1997〕 Ulster-Scots: ''Airish Sea'', (ウェールズ語:Môr Iwerddon)) separates the islands of Ireland and Great Britain. It is connected to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland〔 in the north by the North Channel. Anglesey is the largest island within the Irish Sea, followed by the Isle of Man. The sea is occasionally, but rarely, referred to as the Manx Sea ((アイルランド語:Muir Meann),〔(Electronic Dictionary of the Irish Language )〕 (マン島語:Mooir Vannin), (スコットランド・ゲール語:Muir Mhanainn)).〔(【引用サイトリンク】 Irish Sea Facts )〕 The sea is of significant economic importance to regional trade, shipping and transport, fishing, and power generation in the form of wind power and nuclear plants. Annual traffic between Great Britain and Ireland amounts to over 12 million passengers and of traded goods. == Origin and topography== The Irish Sea has undergone a series of dramatic changes over the last 20,000 years as the last glacial period ended and was replaced by warmer conditions. At the height of the glaciation the central part of the modern sea was probably a long freshwater lake. As the ice retreated 10,000 years ago the lake reconnected to the sea, becoming brackish and then fully saline once again. The International Hydrographic Organization defines the limits of the Irish Sea (with St George's Channel) as follows:
It is connected to the North Atlantic at both its northern and southern ends. To the north, the connection is through the North Channel between Scotland and Northern Ireland and the Malin Sea. The southern end is linked to the Atlantic through the St George's Channel between south eastern Ireland and Pembrokeshire in Wales, and the Celtic Sea. The Irish Sea is composed of a deeper channel about long and wide on its western side and shallower embayments to the east. The western channel's depth ranges from up to in the Beaufort's Dyke in the North Channel. The main embayments Cardigan Bay in the south and the waters to the east of the Isle of Man are less than deep. The Sea has a total water volume of , 80% of which is to the west of the Isle of Man, and a surface area of . The largest sandbanks are the Bahama and King William Banks to the east and north of the Isle of Man and the Kish Bank, Codling Bank, Arklow Bank and Blackwater Bank near the coast of Ireland. The Irish Sea, at its greatest width, is and narrows to . 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「Irish Sea」の詳細全文を読む スポンサード リンク
