Short summary
Faecal pellets (FPs) are a dominant part of the deep ocean carbon fluxes. We compare estimates of FP production, to measurements of FPs in the meso- and bathypelagic. Despite being produced in high numbers in the surface ocean, small FPs are not transferred efficiently to depth. Changes in FP morphology point to the repacking of surface FPs in the mesopelagic and in situ production at depth, highlighting the importance of deep zooplankton communities for the transfer of carbon to the deep ocean.
