What do people know about Sargassum? What do they associate with the algae? And what experiences do they have with them in everyday life? Answers to these questions can be found in the Sargassum local knowledge brochure, available in English, Spanish and Mayan. The booklet is the result of my collaboration with colleagues from CONACYT Mexico, Partners of the Americas, UC Santa Cruz, Group on Earth Observations, and Instituto de Ciencias del Mar y Limnologia. Thanks for having me on board!
