Sargassum muticum Sargassum muticum Sargassum muticum, commonly known as Japanese wireweed, is a large brown seaweed of the genus "Sargassum". It is an invasive seaweed with high growth rate (up to 10 cm per day during spring). It has an efficient dispersion thanks to its floats. "Sargassum muticum" is a brown seaweed, normally brown to yellowish with a length up to 10 m. It is an autotroph that uses energy from sunlight. The photosynthesis is facilitated thanks to aerial vesicles which allows the algae to raise to the surface. "Sargassum muticum" is composed of two distinct parts: a perennial part, which contains
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
