Researchers at Florida Atlantic University's Harbor Branch Oceanographic Institute have released a landmark review tracing four decades of changes in pelagic sargassum—free-floating brown seaweed that plays a vital role in the Atlantic Ocean ecosystem.
Once thought to be primarily confined to the nutrient-poor waters of the Sargasso Sea, sargassum is now recognized as a rapidly growing and widely distributed marine organism, whose expansion across the Atlantic is closely linked to both natural processes and human-induced nutrient enrichment.
