Meet the sargassum belt, a 5,000-mile-long snake of seaweed circling Florida. Earlier this year, ocean scientists raised an alert about the large amount of seaweed drifting in the tropical Atlantic this spring. Picture taken July 20, 2021. Tags: weather. Data from NASA's Terra and Aqua satellites revealed the immense size of a record-breaking algal bloom known as the Great Atlantic Sargassum Belt. 16 Mar 2023 12:31:00. becoming so big they were captured on satellite images. 16 Mar 2023 12:31:00. And it's circling around the Gulf of Mexico and the mid-Atlantic, where the right. “One study that examined sargassum along beaches in Mexico found that 86% of samples had arsenic levels that were higher than the U. The sargassum bloom is one of the largest ever recorded and is easily visible from space. As noted in the satellite imagery, major blooms occurred in every year . Scientists aboard a U. in the satellite imagery does not bode well for a clean beach year. edu) The maps below show Sargassum abundance, with warm colors representing higher values. Today, the patches comprise a 5,500-mile-long, 10 million-ton belt that circulates annually, starting near West Africa and snaking through the Gulf of Mexico. But scientists noticed a change in sargassum levels in 2011, when masses of the seaweed multiplied, gaining in density and size, becoming so big they were captured on satellite images. Led by researchers from the University of South Florida (USF) College of. The challenge has since extended to the contiguous United States as the Great Atlantic Sargassum Belt drifts towards Florida. A satellite image shows a miles-long raft of sargassum. Pictures; Inside the Guardian;. @SamBrockNBC reports. USF scientists use NASA satellite images to track Sargassum, a brown seaweed. Seaweed in seen in the beaches of Miami Beach, Miami, March 10, 2023. 🔴 Video | Researchers at NASA and the University of South Florida continue to warn of a growing bloom of Sargassum seaweed, after satellite imagery capture. The ability to monitor Sargassum globally will allow researchers to. Lumpkin called it "one of the strongest years, but not the strongest" since scientists began closely observing the biomass via satellite imagery in 2011. Sargassum blooms in the Caribbean Sea. Since 2011, a Great Atlantic Sargassum Belt (GASB) has been observed in satellite imagery. Sargassum, as defined by NOAA, is “a genus of large, brown seaweed (a type. The vast mat of brown Sargassum algae extends all the way across the Atlantic Ocean — a distance of about 5,500 miles — and the researchers say the so-called bloom may represent the “new. Seasonal sargassum blooms have exploded in the tropical Atlantic over the past decade and more. Sargassum seaweed blooms in South Florida are particularly bad right now, with areas like the Florida Keys bracing for the worst in March 2023. Satellite images taken in March show the bulk of the mass is still out in the Atlantic Ocean, but traces can be seen coming up into the Caribbean Sea and the Gulf of Mexico. It is expected to be found on beaches in Florida around July, according to one researcher. There had never before been enough sargassum in the sea that it. The boat that can be seen travelling southeast is a large 250 m container ship for reference. 16 Mar 2023 18:56:18. becoming so big they were captured on satellite images. In early dynamical forecasts, satellite imagery and operational 7-day ocean current forecasts were used to predict sargassum drift on timescales . Sargassum seaweed. Barnes and his colleagues at USF’s Optical Oceanography Laboratory track sargassum blooms. According to NASA satellite imagery, the 2023 sargassum bloom is the largest ever recorded: 5,000 miles long, 300 miles wide, and 13 million tons. "That's why we started this research to investigate the large-scale phenomenon with satellite imagery. Since 2011, a Great Atlantic Sargassum Belt (GASB) has been observed in satellite imagery. The sargassum bloom is one of the largest ever recorded and is easily visible from space. After a decade of record-breaking blooms, 2023's sargassum mass is again shaping up to cause headaches (literally and figuratively) for beachside towns and tourists. AFP via Getty Images. Researchers analyzed the visible and near-infrared channels of the imagery to locate the distinctive yellow-brown seaweed in over 53,000,000 . There had never before been enough sargassum in the sea that it. In a recent paper, Wang’s team combined satellite data with field samples and nutrient analyses to provide evidence for possible causes of the bloom (Science 2019, DOI: 10. 16 Mar 2023 12:31:00. In fact, it is. Today, the patches comprise a 5,500-mile-long, 10 million-ton belt that circulates annually, starting near West Africa and snaking through the Gulf of Mexico. Chuanmin Hu and his team from the University of South Florida’s (USF) optical oceanography laboratory had been monitoring it using satellite imagery since 2011 and had seen it explode in size. . image bulk download
