Sargassum change of sea currents due to climate change. Also, nutriments from agricultural fertilizers and wastewater from the cities that end up in the sea could also make the algae bloom. Sargassum Sargassum is a genus of brown (class Phaeophyceae) macroalgae (seaweed) in the order Fucales. Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species. Most species within the class Phaeophyceae are predominantly cold-water organisms that benefit from nutrients upwelling, but the genus "Sargassum" appears to be
Sargassum on wave height and current. On the Caribbean island of Saint Martin, backhoes are also used in the process of clean up once the "Sargassum" weed reaches the shorelines. Researchers say that the "Sargassum" outbreak started in 2011, but it has become worse over the years. As it is cleaned up on the shorelines, in a matter of a week, the shorelines are once again filled in masses. It is still a recurring problem to this date. Several factors could explain the proliferation of "Sargassum" in the area in recent years. These include the rise of sea temperature and the
