Brigitta scientist Ine van Tussenbroek Ribbink, based in Puerto Morelos, Mexico. Specialist sargasses, which we met last year, fully approves our project “The ocean cleaner” and our Sargaboat !
“Sargazo is not a matter of tourist image, but an ecological and even health problem”

The hoteliers of ancestry such as José Chapur Zahoul (Palace Resorts), Carlos Gosselin Maurel (Paradise of the Beautiful), Abelardo Vara Rivera (Grupo Omni) and the late Roberto Antonio Cintrón Díaz del Castillo always talked about collecting sargassum to occupy it in industries such as the cosmetics or let it dry because it would become sand. How wrong they were.
Brigitta Ine van Tussenbroek Ribbink, researcher at the Academic Unit of the Reef Systems Unit of the National Autonomous University of Mexico (UNAM), in the municipality of Puerto Morelos, threw down the myths of the hoteliers of Quintana Roo.
The Mayan Journey had access to the synthesis of the research carried out by the doctor of Dutch origin, who initially says that she does not know the origin of the talofite, which is a different species from the Sargasso Sea, in the North Atlantic, which does not It has a coastline and constitutes an immense floating island, between Florida and the Azores Islands, which belongs, in part, to the so-called “Bermuda Triangle”.
“It is thought that it has arrived so much sargassum because of the excess nutrients that reach the sea by means of rivers, and it can double its biomass – amount of accumulated matter – in 20 days. The ecological impact on beaches and places where it is concentrated is for a long time due to its chemical components, and it affects the flora, fauna, reefs, beaches and the aquifer mantle “.
The researcher pointed out that algae releases sulfuric acid that causes allergies, and some microorganisms that live in them are also toxic to the skin, and the gases that it releases can be harmful. Sargassum has caused the death of fish, turtles, octopuses, sharks; and the turtles can not reach spawning and the offspring can not reach the sea.
“For the quantities of sargassum that have reached our coasts a thousand times more phosphorus is generated, causing more algae to grow than corals, and in brown tide (brown water), the amount of oxygen in the water decreases causing death of fish and the proliferation of bacteria, “explained the scientist.
Tussenbroek Ribbink points out that sargassum also severely and severely affects seagrasses and grasslands, causing more erosion, and it has been seen that the impact on the beach (due to the exaggerated quantity that has arrived) lasts for more than a year, and the impact on the prairie can extend up to 60 years.
“Contrary to what is believed, burying it on the beach damages the ecosystem irreversibly; the ideal is to create a system to collect it at sea, shortly before it reaches the beach. It is not advisable to do it in the open sea because it is an ecosystem and refuge of marine species, and it is essential for the life cycle.
“If you have already reached the beach, you should not use heavy machinery for your eviction, as the equipment tames more the sand contributing to erosion. When placed in sascaberas the water table is contaminated due to its high concentrations of phosphorus and arsenic. It is very important to tear down the myth that sargassum turns into sand. ”
The researcher of the Academic Unit of the Reef Systems Unit of the UNAM, in Puerto Morelos, warns that the talofite emits gases and it is believed that it can be used to produce biofuels and fertilizers; however, more research is needed. In addition, studies so far advise not to use it directly as a subscription.
“It is recommended to mix it in a low percentage with some type of compost because its natural composition does not allow its use for alimentary purposes due to its high concentration of arsenic, so the preparation of cookies must be stopped because its consumption is dangerous”.
Finally, the researcher clarifies in her study that “it is important to reflect on the fact that the subject of sargassum is not a matter of tourist image, but an ecological and even health problem”.
Over the weekend, more than 100 tonnes of sargassum were removed from the coasts of the municipality of Solidaridad and Othón Pompeyo Blanco (Mahahual), but the algae continues to land on the coasts of Xcalacoco, Punta Esmeralda, Mamitas, El Faro and Piñatas.
