It’s become an recurring theme each year to hear about the best parts of the Caribbean and Gulf being overrun with weed. Not the “puff puff give” kind, but the pain in the butt kind. Sargassum. It can be everywhere. And not just in neat lines along the rips but in mats and globs and clumps as far as the eye can see. The National Oceanic and Atmospheric Administration reported that since 2011, large accumulations of Sargassum have become a remerging problem in the Caribbean Sea, Gulf of Mexico and tropical Atlantic.
