Short summary
Vertical migration of zooplankton has rarely been studied under the effect of a variable community structure, which depending on the behavior and size of its groups can strongly alter the magnitude of C being actively taken to depth by migrants. Here, we address this issue in a highly productive upwelling system, where a high amount of zooplankton can daily move below the mixed layer despite presence of an extremely low–oxygen water and so contribute to a significant export of C to depth.
