Sargasse Guadeloupe

Sargassum (Sargassum fluitans or Sargassum natans) is a floating brown algae. Unlike many algae species, it does not need to take root.

Sargassum is made up of light yellow leaves with serrated edges, air-filled cells (pneumatocysts), also light yellow, which also serve as floats, and light or dark brown stems. Sargassum can form large, dense, thick mats, and they are a boon to many fish and crustaceans that shelter in them.

Once washed ashore on the coasts and beaches, Sargassum decomposes and turns black. It forms deposits that invade and give off a foul odor.

The beaches are often deserted, because it is often impossible to swim without being tickled by a bank of Sargassum or even to sunbathe on the beach (foul odor).

The municipalities and certain associations take care of clearing the Sargassum washed ashore on the beaches, but hardly have they finished than it must already be started again, as a new mat of Sargassum washes ashore on the beaches.

Scientific research that studied the movement of Sargassum found that the Sargassum that invades our coasts each year came from north of the mouth of the Amazon and not from the Gulf of Mexico.
