What is Sargassum?

Sargassum is a brown seaweed with berrylike air bladders, typically forming large floating masses. This brown seaweed provides a crucial habitat for many marine species, including endangered sea turtles which, upon hatching on our beaches, make their way out to the Sargassum to spend their juvenile years feeding and growing amongst the seaweed mats. Sargassum comes from the largest bloom of macroalgae in the world, the Great Atlantic Sargassum Belt (GASB), which blankets the surface of the tropical Atlantic Ocean from the west coast of Africa to the Gulf of Mexico.
