Sargasso Sea

Map of the Sargasso Sea
The Sargasso Sea in the North Atlantic is bounded by the Gulf Stream on the west, the North Atlantic Current on the north, the Canary Current on the east, and the North Equatorial Current on the south.

The Sargasso Sea (/sɑːrˈɡæs/) is a region of the Atlantic Ocean bounded by four currents forming an ocean gyre.[1] Unlike all other regions called seas, it has no land boundaries.[2][3][4] It is distinguished from other parts of the Atlantic Ocean by its characteristic brown Sargassum seaweed and often calm blue water.[1]

The sea 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, the four together forming a clockwise-circulating system of ocean currents termed the North Atlantic Gyre. It lies between 20° and 35° north and 40° and 70° west and is approximately 1,100 kilometres (600 nautical miles) wide by 3,200 km (1,750 nmi) long. Bermuda is near the western fringes of the sea.

While all of the above currents deposit marine plants and refuse into the sea, ocean water in the Sargasso Sea is distinctive for its deep blue color and exceptional clarity, with underwater visibility of up to 60 m (200 ft).[5] It is also a body of water that has captured the public imagination, and so is seen in a wide variety of literary and artistic works and in popular culture.[6]
