Bras d'Or Lake is an inland sea, or large body of partially fresh/salt water in the centre of Cape Breton Island in the province of Nova Scotia, Canada. Bras d'Or Lake is sometimes referred to as the ''Bras d'Or Lakes'' or the ''Bras d'Or Lakes system''; however, its official geographic name is ''Bras d'Or Lake''〔(【引用サイトリンク】title=Bras d'Or Lake )〕 as it is a singular entity. Canadian author and yachtsman Silver Donald Cameron describes Bras d'Or Lake as "A basin ringed by indigo hills laced with marble. Islands within a sea inside an island." The lake is connected to the North Atlantic by natural channels, the Great Bras d'Or Channel north of Boularderie Island and the Little Bras d'Or Channel to south of Boularderie Island, connect the northeastern arm of the lake to the Cabot Strait. The Bras d'Or is also connected to Atlantic Ocean via the Strait of Canso by means of a lock canal completed in 1869—the St. Peters Canal, at the southern tip of the lake. There are several competing explanations of the origin of the name "Bras d'Or". The most popular is that the first Europeans to discover and subsequently settle the area were French, naming the lake ''Bras d'Or'' meaning "arm of gold"; this likely referring to the sun's rays reflected upon its waters. However, on the maps of 1872 and earlier, the lake is named "Le Lac de Labrador," (or more simply "Labrador")〔(【引用サイトリンク】 Carte du Canada ou de la Nouvelle France et des decouvertes que y ont ete faites.

The literal meaning of Labrador is "Laborer."〔(【引用サイトリンク】title=Bras d'Or Lake (C. B.) )〕 In a paper prepared by the late Dr. Patterson for the Nova Scotia Historical Society he says he believed the name Bras d'Or came from the Breton form of Bras 'd'eau arm of water or of the sea. The Mi'kmaq Nation named it ''Pitu'pok'', roughly translated as "long salt water". With an area of approximately 1,099 square kilometres,〔(【引用サイトリンク】title=Facts About Canada: Lakes )〕 the extents of Bras d'Or Lake measures roughly 100 km in length and 50 km in width. Surrounded almost entirely by high hills and low mountains, the shape of the lake is dominated by the Washabuck Peninsula in the centre-west, Boularderie Island in the northeast, and a large peninsula extending from the centre-east dominated by the Boisdale Hills. The Washabuck Peninsula and Boisdale Hills divide the lake into northern and southern basins, linked by the 1 km wide Barra Strait. The maximum depth of Bras d'Or Lake of 287 metres is found in the St. Andrews Channel. This area was designated a Biosphere Reserve by UNESCO in 2011.〔(【引用サイトリンク】title=UNESCO Biosphere )〕 == Subdivisions == The effect of local topography has resulted in the following major components of Bras d'Or Lake: ''Northern Basin'' * Great Bras d'Or * Little Bras d'Or * St. Andrews Channel * St. Patricks Channel * Baddeck Bay * Nyanza Bay * Whycocomagh Bay ''Southern Basin'' * Denys Basin * St. Peters Inlet * East Bay * West Bay The largest part of the lake measures approximately 25 kilometres across in the southern basin, framed by East Bay and West Bay with Denys Basin to the north and St. Peters Inlet to the south. The Barra Strait is crossed by highway and railway bridges running between the Washabuck Peninsula and the Boisdale Hills. 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「Bras d'Or Lake」の詳細全文を読む スポンサード リンク
