Sargassum warnings
Seaweed, Sargassum, sargasso, Heterokontophyta ... different names for the same thing - more than a nagging nuisance, a potentially serious health hazard. It has been clogging beaches in the Caribbean, causing distress to locals and loss of tourism. The boats in the Volvo Ocean Race struggled in the Sargasso Sea this year. VOR even compiled the best video footage of the sailors struggling to stay free of the weed.
