Great Atlantic Sargassum Sea

The Great Atlantic Sargassum Sea refers to large, floating mats of sargassum seaweed that drift across parts of the Atlantic Ocean and Caribbean Sea. These mats are dense aggregations of brown seaweed that provide habitats for marine life, but sometimes grow excessively, impacting beaches, boating, and coastal ecosystems. Sargassum naturally occurs in the ocean, but recent increases in quantity are believed to be driven by changing climate conditions, nutrient runoff, and other environmental factors. While it supports biodiversity, large accumulations can cause environmental and economic challenges, prompting ongoing research and management efforts.
