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

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

Sargassum has lengthy fashioned substantial blooms within the Atlantic, and scientists have noticed huge accumulations since 2011. Nonetheless, this 12 months’s sargassum bloom, which spans greater than 5,000 miles from the coast of Africa to the Gulf of Mexico, will be the largest in historical past.

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

In line with Lapointe, this 12 months’s Sargassum bloom began early and doubled in measurement between December and January. Lapointe advised 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 wholly new oceanographic phenomenon that’s creating such an issue — actually a catastrophic downside — 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 folks in Barbados have been using “1,600 dump vans a day to wash the seashores of this seaweed to make it appropriate for vacationers and recreation on the seashores.”

Why 2023 is the 12 months of sargassum

In line 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 12 months to 12 months relying on ecological elements influenced by adjustments in vitamins, precipitation and wind patterns. That is just like the way in which crops and crops on the bottom can change from 12 months to 12 months.

In line with Goni, ocean currents also can have an effect on annual development and the quantity of sargassum that accumulates. The ocean accommodates 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 Eighties. The large development of the bloom, the researchers mentioned, is probably going because of this enhance.

In line with the Environmental Safety Company, rivers which might be polluted with phosphorus and nitrogen from human actions corresponding to agriculture and fossil gasoline 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 as we speak, it might change tomorrow,” he mentioned.
