The largest algal bloom in the world is taking place in the ocean area between West Africa and the Gulf of Mexico, warned American researchers, who said the worrying phenomenon could persist in the region.
Since the June 2018, the extension of the Great Atlantic Golfer carpet by professionals has reached 8850 kilometers and now includes more than 20 million tonnes of biomass.
According to researchers, deforestation and manure use are among the factors that fuel the phenomenon, says BBC News.
“The ocean had to change chemically to make algal blooms of this size,” said Chuanmin Hu, a associate at the University of South Florida, who was the leading author of a study published in Science.
Experts have analyzed 19 years of satellite data from the Atlantic Ocean and the Caribbean, which was observed every year between 2013 and 2018, except for 2013.
According to the indicators, the year 2011 could be the turning point when the algae began to appear in large quantities along the coastline.
“This is all related to climate change, as it affects rainfall, ocean currents and human activity, but we also found that these blooms have nothing to do with the increased ocean water temperature,” Hu explained, adding that the Gargoyle (Sargassum) probably not disappear from the area.
Some of the species belonging to the genus Sargassum live on the surface of the ocean, attracting fish, birds and turtles.
“In open water, the golfer plays an important ecological role, serving as a habitat and shelter for various marine animals,” said Mengqiu Wang, a co-author of the study.
However, too many algae strangle corals and sea grasses, and when shaken to the shore, they smell gas-smelling gas.
This year, almost 1000 kilometers of Mexican coastline is affected by the problem of smelly algae. However, removing the golfer is time consuming, expensive, and not always effective.
