Record amount of seaweed is choking shores in the Caribbean

A record amount of seaweed is smothering Caribbean coasts from Puerto Rico to Barbados as tons of brown algae kill wildlife, choke the tourism industry and release toxic gases. More than 24 million tons of sargassum blanketed the Atlantic in June, up from 18.8 million tons in May, according to a monthly report published by the University of South Florida’s Optical Oceanography Lab that noted “a new historical record.” July saw no decrease of algae in the Caribbean Sea, said Chuanmin Hu, an optical oceanography professor who helps produce the reports. “I was scared,” he recalled feeling when he saw the historic number for June. He noted it was 20% higher than the previous record set in May 2018. Seaweed covers the Atlantic shore in Frigate Bay, St. Kitts and Nevis, Wednesday, A...

Data also reveals increase in amount and length of reef-disrupting abnormal heatwave events A new analysis outlines 150 years of sea-surface temperature history throughout the Greater Caribbean region, highlighting significant warming trends that have disrupted coral reef ecosystems. Colleen Bove of the University of North Carolina at Chapel Hill and colleagues present these findings in the open-access journal PLOS Climate on March 9. In addition to heating the atmosphere, climate change caused by human activity heats the world’s oceans, disrupting marine ecosystems. Previous research has documented dramatic warming-induced changes to coral reef ecosystems worldwide—and in the Caribbean in particular—identifying such effects as mass coral mortality through coral bleaching and loss o...

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. A beach covered with sargassum is pictured near a hotel in Cancun, Me...
