The Sargasso Sea is a region in the North Atlantic Ocean that is bounded by the currents forming the North Atlantic Gyre.
The currents that form the North Atlantic Gyre and trap the Sargassum seaweed are the Gulf Stream (to the west), the North Atlantic Current (to the north), the Canary Current (to the east), and the North Atlantic Equatorial Current (to the south). All three currents listed in the options (North Atlantic current, Canary current, North Atlantic Equatorial current) are part of the boundary currents that define and circulate around the Sargasso Sea, contributing to the accumulation of floating material within it.
The Sargasso Sea is unique as it is the only sea in the world that is defined by ocean currents rather than by land boundaries. Its calm, clear waters are home to a unique ecosystem, including the Sargassum seaweed which provides habitat for numerous marine species. The lack of strong currents within the gyre allows the seaweed and other floating debris to accumulate.
