9-Meter Mountains of Sargassum: A Growing Environmental and Public Health Concern in the French Caribbean In several French Caribbean islands, massive piles of decomposing sargassum are now reaching heights of up to 9 meters. These are no longer simple algae accumulations along the shoreline. They resemble mountains. 🎥 Videos and field images show heavy machinery […]

Photo of the French army coming to pick up sargassum in 2018 – 7 ppm of H₂S Measured on a Sargassum Pile in Playa del Carmen: A Concerning Level A recent scientific report filmed in Playa del Carmen, Mexico, revealed a concentration of 7 ppm of hydrogen sulfide (H₂S) measured directly above a sargassum pile.

“A New Study Reveals the Triggering Factor Behind Massive Sargassum Blooms” Since 2011, massive sargassum strandings have disrupted marine ecosystems and coastal communities in the tropical Atlantic. A recent study, published in Communications Earth & Environment, highlights a key element behind this phenomenon: an extreme North Atlantic Oscillation (NAO) event in 2009-2010. An Ecological Shift

Puerto Morelos, Quintana Roo. The beaches of Mexico, natural treasures cherished by millions of visitors, are facing a growing threat: sargassum.

In an effort to address the challenges posed by massive accumulations of Sargassum on the coast of Puerto Rico, the Department of Natural and Environmental Resources (DRNA) has recently unveiled its final management protocol. A key decision in the protocol is the formal exclusion of Sargassum use for agricultural or human consumption purposes, including composting.
