Last Friday, July 28, 2023, we conducted the field trip for the microplastic characterization and reduction module at San José Lagoon, Suárez Canal, and Piñones Lagoon. We thank the volunteers who accompanied us: Yojanny Guzmán, Hanna Rodríguez, Maria García, and Naiara Gonzalez, as well as Captain David Ramírez, who led the boat trip.
