January 15, 2024: Another record blob of sargassum was measured in the Central Atlantic Ocean

University of South Florida scientists have reported a significant increase in sargassum, a type of seaweed, in the Central Atlantic, near the Caribbean Sea. As of December 2023, the mass of sargassum reached nearly 5 million metric tons, a substantial increase from the 1 million metric tons recorded at the same time in the previous year.

This amount sets a new historical record for the region. Despite a 15% decrease in May 2023, which deviated from the 2022 record high of 22 million metric tons, researchers anticipate 2024 to be another major year for sargassum growth.

Currently, the majority of this seaweed mass is located about 500 miles east of the Caribbean Sea, with significant blooms also observed near Venezuela’s Orinoco River, affecting areas like Trinidad and Tobago and the southern Caribbean Sea.


July 18: Latest seaweed news and photos from Florida

Last spring, Florida’s renowned beaches faced an unprecedented challenge with the arrival of a massive, foul-smelling seaweed mass known as the Great Atlantic Sargassum Seaweed Belt.

However, there’s good news as recent findings by scientists from the University of South Florida’s Optical Oceanography Lab indicate that the seaweed belt in the Gulf of Mexico has significantly diminished, shrinking by an impressive 75% last month.

What’s causing the seaweed problem?

A 2020 study, involving research from the National Oceanic and Atmospheric Administration (NOAA), has linked the surge in sargassum in the tropical Atlantic Ocean to a shift in the North Atlantic Oscillation (NAO) around 2009-2010.

This change led to stronger west and south winds, which dispersed sargassum from the Sargasso Sea into the tropical Atlantic, where it received more sunlight and nutrients from ocean upwelling.

The longevity of this increased sargassum presence is uncertain, with NOAA’s Rick Lumpkin noting the possibility of a similar event occurring in the past, followed by a decline of the Sargassum belt after several decades.

What could be done? These are possible alternative uses of sargassum heading to Florida, according to a new startup

The surge of sargassum seaweed in recent times has triggered businesses to explore novel methods of eliminating it, and its potential uses are already manifold.

Scientists and entrepreneurs aspire to transform it into syrup, bricks, and conceivably even jet fuel. Carbonwave, an organization based in Boston and Puerto Rico, is utilizing it as a constituent in fertilizer, cosmetics, and even synthetic leather.
