Sargassum Seaweed Surges: South Florida Beaches Drowning
12 May
Summary
- Unusually heavy sargassum influx is overwhelming South Florida beaches this season.
- Millions of metric tons of seaweed are currently floating across the Atlantic.
- Scientists explore repurposing sargassum as a food ingredient, pending research.
South Florida's coast is currently facing an unusually dense influx of sargassum seaweed. Beach visitors have encountered extensive seaweed coverage, accompanied by the emergence of pests and a strong odor as the algae dries. This situation is reportedly worse than in previous years.
An estimated 10 million metric tons of sargassum are estimated to be adrift in the Atlantic Ocean. Coastal communities face significant expenses for seaweed removal. To aid in preparedness, NOAA has increased its satellite tracking frequency from weekly to daily updates, improving resolution for accurate identification.
Meanwhile, a promising avenue for managing the seaweed involves repurposing it. Researchers at Florida International University are exploring methods to extract alginate from sargassum, a compound usable as a thickening agent in food products like ice cream and sauces.
This innovative approach aims to shift the perspective from disposal to opportunity. However, the seaweed is not yet classified as a food source, and further research, funding, and regulatory approvals are necessary before any commercial applications can be realized. Public support for finding new uses for the abundant seaweed exists.
