From 11 to 24 of September, our colleagues Rodrigo Almeda, the coordinator of the studies concerning the impact on plankton, and Alicia Herrera participated in the MANTLE Project. They flew to Sweden, to the Mesocosm Facility at Umeå Marine Sciences Center (MF-UMSC), where both work in the mesocosm experiment to explore how key biological processes influence the distribution and effects of different types of MPs in marine ecosystems (on plankton and benthos communities under environmentally realistic scenarios).
