The Sargasso Sea is a region of the Atlantic Ocean bounded by four currents that form a gyre. Bermuda is located near the western edge of the sea. In contrast to all other regions known as seas, there are no land boundaries. Its characteristic brown Sargassum sea grass and often calm blue waters distinguish it from other parts of the Atlantic Ocean. Geographically, the Sargasso Sea is situated in the North Atlantic Ocean, approximately between 20° and 35° north latitude, and 40° and 70° west longitude. The four currents that enclose this unique region are the Gulf Stream to the west, the North Atlantic Current to the north, the Canary Current to the east, and the North Equatorial Current to the south. These currents converge to form a clockwise-rotating gyre, which in turn creates a calm and peaceful environment within the sea. The Sargasso Sea is also renowned for its exceptional biodiversity. The Sargassum sea grass, which gives the sea its name, provides a habitat for a wide range of marine species, including fish, crustaceans, and mollusks. The sea's calm waters and warm temperatures, ranging from 18°C to 28°C, create an ideal environment for these species to thrive. Additionally, the sea's unique location at the intersection of several ocean currents makes it a vital stopover point for many migratory species, including Sea Turtles, whales, and fish. Furthermore, the Sargasso Sea serves as a migration route for catadromous eel species including the European Eel, the American Eel, and the American Conger Eel.
