“No todo es Sargazo”:Aprendizajes en un proyecto de ciencia ciudadana marino-costera

The effects of the abundant arrival of macroalgae, such as Sargassum, to the Yucatan Peninsula motivated the monitoring of beach-cast seaweeds through a citizen science project aimed at affected and interested populations. Questionnaires and semi-structured interviews were employed to analyse the learning outcomes of 18 participants (16 to 18 years) from the project's first stage. Among the findings, the interrelation of new disciplinary learning about macroalgae and skills for fieldwork stood out. Participants showed renewed and positive attitudes toward science and beach-cast seaweeds. We reflect on what factors drove their learning and research skills when addressing the scientific objectives, including the relevance of the problem, the introductory workshop, and the socialisation between the scientists and the participants.
