Marine Protected Areas (MPAs): Sargasso Sea. Photo 72: Map of Sargasso Sea. (NOAA Photo Library.) The Sargasso Sea is located entirely within the Atlantic Ocean and characterized by the presence of holopelagic Sargassum. Holopelagic Sargassum is free-floating algae that remains in the open ocean for its entire life cycle.
