The quietest current on Earth is the Sargasso Sea, which is located in the center of the Atlantic Ocean. This current got its name due to the huge accumulations of sargassum algae that form in its waters. The current of the Sargasso Sea is very slow and practically not felt, its speed is only a few centimeters per second. However, this current is of great importance for the ecosystem of the Atlantic Ocean, as it is the habitat of many species of marine animals and birds.
