Scientists come closer to solving Caribbean seaweed mystery - (Reuters article)

(Reuters) - Scientists were baffled when a band of seaweed longer than the entire Brazilian coastline sprouted in 2011 in the tropical Atlantic - an area typically lacking nutrients that would feed such growth.





A group of U.S. researchers has fingered a prime suspect: human sewage and agricultural runoff carried by rivers to the ocean.


The science is not yet definitive. This nutrient-charged outflow is just one of several likely culprits fueling an explosion of seaweed in warm waters of the Americas. Six scientists told Reuters they suspect a complex mix of climate change, Amazon rainforest destruction and dust blowing west from Africa’s Sahara Desert may be fueling mega-blooms of the dark-brown seaweed known as sargassum.


In June 2018, scientists recorded 20 million metric tons of seaweed, a 1,000% increase compared with the 2011 bloom for that month.


“There are probably multiple factors” driving the growth, said oceanographer Ajit Subramaniam at Columbia University. “I would be surprised if there is one clear villain.”
