Sargassum

The Islands of the Caribbean, inclusive of Antigua, Barbuda and Redonda, have been affected by Sargassum Seaweed (Sargassum sp.) since 2011. Sargassum blooms appear to originate off the coast of South America and have been affecting the Caribbean island chain with varying ecological and anthropogenic/economic effects. Sargassum seaweed grow on the ocean surface and provide ecosystem services such as habitat for juvenile marine organisms (e.g. fish, turtles) and foraging areas while on the sea, but biologically degrade upon contact with the shoreline, leading to negative impacts.
