An annual seaweed bloom blossomed early this year in the Atlantic Ocean and there's a lot of it. Scientists say the great Atlantic sarcasm belt stretches across 5000 miles when it reaches the beaches of the United States and Caribbean islands in Mexico over the next few months. It will be a mess. The brown seaweed is a thick algae that smells like rotten eggs when it decays. So it'll keep coastal and resort workers very busy and while this year's bloom is clearly big, it was bigger back in 2018.
