A floating blob of seaweed 5,000 miles across , span near the whole breadth of the Atlantic Ocean , is maneuver for Florida ’s Atlantic Coast . The sargassum alga , a Robert Brown , forking , stringy seaweed that can change by reversal brine clay - colored when present in orotund quantities , is probable to have serious problem for the Sunshine State as well as the Caribbean and theatrical role of Mexico , per multiple reports .
In retiring sizable seaweed blooms , sargassum has clogged up beach with C of loads of sticky , matte alga . To make matters even less likeable : The seaweedemits hydrogen sulfide gasas it decay , producing a rotten - egg like olfactory perception and causingpotential respiratory provocation as well as digestive and neurological problemsfor people nearby .
The thick flotilla of organic matter can also terminate up clogging power plant intakes , desalination water system plants , and embarrass boat traffic .

Then there are the bionomical impacts of massive sargassum flower . The algae allow for some of the only wildlife habitatin the opened sea of the Sargasso Sea , where the piles of seaweed grow and swim most of the prison term . However , in recentdamaging mega - bloom result , the algae is a less welcome invasion — particularly in close - shoring ecosystem . Sargassum blooms canchoke up shallow coastal water , hinder out light , degrade water timbre , clog coral Rand , deplete oxygen , toss off sea life , and more .
This year ’s bloom is starting month sooner than usual and seems probable to be as bad as — if not bad than — any anterior sargassum issue on record . “ It ’s unbelievable , ” Brian LaPointe , an ecologist at Florida Atlantic University , enjoin NBC News . “ What we ’re seeing in the satellite imaging does not foretell well for a blank beach class . ” Researchersuse orbiter datato keep tabs on the algae .
Along Mexico ’s Caribbean Sea seashore , overweening amountsof the alga have begin to appear on some beaches . holiday resort have readied their plansto remove the seaweed from tourist spots and effort to salvage their income . In brief : hundreds of people will knead 24/7 to shovel and cart aside the algae as it washes up . Cancun officials have said the nautical stuff will be turned into biofertilizer , according tothe Cancun Sun .
In Florida , beach in Key West have also already begun to incur algal inundation , LaPointe told NBC News . There too , resorts and other individual beach owners work tomechanically murder the seaweedfrom the Amandine Aurore Lucie Dupin . Florida ’s Gulf Coast is already enduring one type of algal bloom , as anongoing “ red tide ” event wipe out dozens of Pisces and other sealife . With the incoming seaweed apocalypse , the peninsula would be hem in on both position by the effect of a man - mud up pelagic ecosystem .
Sargassum has long been a part of the Atlantic ’s marine godsend - and - bout system , but occurrent of the seaweed and its seasonal cycles seem to be shift — to the detriment of humans and the surround .
The seaweedhas bloomed en massemultiple times in late years , with particularly large - scale occurrencesrecorded repeatedly since 2011 . These events almost always happen in the summertime . But this year ’s bloom set off months earlier than normal , andscientists have indicatedthis current volcanic eruption of algae could eventually fall in the record for the large sargassum bloom ever immortalize .
Already , the amount of the seaweed present in the Atlantic has broken at least one monthly disc . Back in February , sargasso scientist Chuanmin Hu of the University of South Floridatold First Coast Newsthat the algae ’s ontogeny in January 2023 “ set a record for all previous January calendar month . ”
Though it ’s not certain what ’s responsible for for this year ’s early and significant sargassum blooming , both nutritive pollution and mood change are thought to contribute to the increasing severity of the seaweed ’s seasonal proliferation . Things like farming runoff , sewage , tempest events , upwellings , Saharan junk storms , and deforestation may drive aflood of nutrients into the ocean that fuels rapid algal growth . Warmer piddle , shifts in maritime upset , andincreasing rainstorms causing runofffrom the Amazon drainage basin — all tempt by mood variety — are also thought to be factors .
