During the late hurricane season, swaths of seaweed known as Sargassum, from the Sargasso Sea, drift across the Atlantic sometimes landing on the beach shore. Not always a comfortable or attractive addition to a beach, this seaweed does provide great cover for fish and vital feeding grounds. It is also great for fertilizer and compost.

But although a natural occurrence, in recent years there has been a massive Sargassum Seeweed bloom, resulting in large quantities inundating beaches all over the Caribbean and the Americas.  It is believed that warming ocean temperatures and increased nutrients due to climate change are the cause.  Find out more about the Sargasso Sea here.
