A thick carpet of "smelly" sargassum seaweed has washed up on Florida's Delray Beach on July 22.

The filmer told Newsflare: "The seaweed, which originates in the Atlantic Ocean off Brazil and in the Caribbean Sea, blew to shore from the Gulf Stream on strong easterly winds.

"Delray Beach tries to deal with the seaweed by using tractors to plough it under, which, with the changing tides shifting the sand around, isn't always successful."

The seaweed can get caught in the propellers of boats and it releases a distinct smell as it decays. The plant generally inhabits shallow water and coral reefs.

Sure as the departure of winter's snowbirds, a thick carpet of sargassum seaweed has returned to South Florida beaches this summer. The seaweed, which originates in the Atlantic Ocean off Brazil and in the Caribbean Sea, blew to shore from the Gulf Stream on strong easterly winds. Scientists believe popular vacation destinations in Florida, Mexico, and the Caribbean are being inundated by more of the smelly seaweed every year due to warming oceans and an overabundance of fertilizer washing into the sea. Both create prime seaweed growing conditions.
