Sargasso Sea
The Sargasso Sea is a region in the gyre in the middle of the North Atlantic Ocean. It is the only sea on Earth which has no coastline. It is bounded on the west by the Gulf Stream; on the north, by the North Atlantic Current; on the east, by the Canary Current; and on the south, by the North Atlantic Equatorial Current. This system of ocean currents forms the North Atlantic Gyre. All the currents deposit the marine plants and refuse they carry into this sea.
The Sargasso Sea is 1,107 km wide and 3,200 km long (700 statute miles wide and 2,000 statute miles long). It stretches from roughly 70 degrees west to 40 degrees west, and from 20 degrees north to 35 degrees north. Bermuda is near the western fringes of the sea. The ocean water in the Sargasso Sea is distinctive for its deep blue color and exceptional clarity, with underwater visibility of up to 61 m (200 ft).
==History==
The naming of the Sargasso Sea after the Sargassum seaweed traces back to the early 15th century Portuguese explorations of the Azores Islands and of the large "volta do mar" (the North Atlantic gyre), around and west of the archipelago, where the seaweed was often present. The Sargasso Sea was first fully crossed by the expedition of Christopher Columbus in 1492, who was amazed by the masses of seaweed he encountered.〔(【引用サイトリンク】Wide Sargasso Sea )〕 However, the sea may have been known to earlier mariners, as a poem by the late 4th century author, Rufus Festus Avienus, describes a portion of the Atlantic as being covered with seaweed, citing a now-lost account by the 5th-century BC Carthaginian Himilco the Navigator.
