What is the Sargassos Sea marine ecoregion?
The North Atlantic Gyre is a huge swirl of clear, nutrient-poor water. It is often called an “ocean desert,” with little food or biodiversity. Still, drifting animals like jellyfish and tuna travel its currents. It also helps move heat around the planet. The North Atlantic subtropical gyre is the most iconic and historically stable area where Sargassum naturally accumulates, forming the Sargasso Sea ecosystem.
