In which ocean is the Sargasso Sea located?

The Sargasso Sea is located in the Atlantic Ocean.

More precisely, it is a region of the North Atlantic enclosed by a clockwise system of ocean currents rather than by coastlines. The Gulf Stream forms its western boundary, the North Atlantic Current its northern edge, the Canary Current its eastern side, and the North Atlantic Equatorial Current its southern boundary. This makes it the only named sea without land boundaries.

The sea takes its name from Sargassum, a floating brown macroalga that gathers in large golden mats at the surface. Portuguese sailors used names related to sargaço for the seaweed, and Christopher Columbus wrote in 1492 about dense weed and calm winds in the region. Contrary to old stories, the seaweed usually does not trap ships; calm conditions in the horse latitudes caused many historical sailing difficulties.

The Sargasso Sea is also an important nursery and migration zone. European and American eels spawn there, while young loggerhead turtles use floating Sargassum as shelter. Bermuda lies near its western margin, but the sea itself is defined by currents, so its boundaries can shift.
