5,000-Mile-Lengthy Seaweed Blob Heading To Florida, Mexico, And Dominican Republic

The Caribbean coasts of Florida, Mexico, the Dominican Republic and different nations are threatened by a large mass of sargassum seaweed that has accrued within the Atlantic Ocean. This mass may put a major damper on the vacationer season.

Sargassum has lengthy shaped substantial blooms within the Atlantic, and scientists have noticed huge accumulations since 2011. Nevertheless, this yr’s sargassum bloom, which spans greater than 5,000 miles from the coast of Africa to the Gulf of Mexico, could be the largest in historical past.

Dr. Brian Lapointe, a researcher at Florida Atlantic Faculty’s Harbor Department Oceanographic Institute, predicts the algae might be seen on Florida seashores starting in July because the patch, presently transferring westward, makes its means via the Caribbean and up into the Gulf of Mexico this summer time.

In accordance with Lapointe, this yr’s Sargassum bloom began early and doubled in measurement between December and January. Lapointe instructed CNN’s Rosemary Church that the mass “was bigger in January than it has ever been since this new area of sargassum development started in 2011.” 

“That is a completely new oceanographic phenomenon that’s creating such an issue — actually a catastrophic drawback — for tourism within the Caribbean area the place it piles up on seashores as much as 5 or 6 toes deep,” Lapointe added.

He talked about that individuals in Barbados have been using “1,600 dump vehicles a day to wash the seashores of this seaweed to make it appropriate for vacationers and recreation on the seashores.”

Why 2023 is the yr of sargassum

In accordance with Dr. Gustavo Jorge Goni, an oceanographer on the Nationwide Oceanic and Atmospheric Administration’s Atlantic Oceanographic and Meteorological Laboratory, the abundance of algae can change from yr to yr relying on ecological components influenced by modifications in vitamins, precipitation and wind patterns. That is just like the best way vegetation and crops on the bottom can change from yr to yr.

In accordance with Goni, ocean currents also can have an effect on annual development and the quantity of sargassum that accumulates. The ocean comprises each phosphorus and nitrogen, which the algae can use for meals.

Lapointe found that nitrogen concentrations had elevated by 45% after taking samples from the area the place the sargassum originated and in contrast them to earlier samples from the Nineteen Eighties. The super development of the bloom, the researchers stated, is probably going as a consequence of this improve.

In accordance with the Environmental Safety Company, rivers which are polluted with phosphorus and nitrogen from human actions resembling agriculture and fossil gas manufacturing can discharge these substances into the ocean.

Goni additionally warns that since analysis into these sargassum accumulations remains to be in its infancy, it’s conceivable that data of the expansion of the algae will change over time.

“No matter we consider we all know in the present day, it could change tomorrow,” he stated.
