Short summary

In the Scotia Sea, the zooplankton community shifting from a herbivorous to omnivorous diet strongly influences the chance of faecal pellets to reach the bottom. Faecal pellet flux was mainly a product of the vertically migrating and deeper-dwelling zooplankton in the iron-fertilized and iron-limited region respectively. The results demonstrate that the behaviour of the zooplankton community plays a critical role in controlling the quantity and quality of carbon exported in this area.
