| Research Abstract |
The aim of the present study is to evaluate the impacts of zooplankton community to downward carbon flux, which have been ignored. Fecal pellets were egested by the predominant taxonomic groups in zooplankton biomass at the surface, and were also consumed and fragmented by these groups during sink. Compared with the zooplankton fecal pellets which was largely changed or declined during sink, respiratory flux transported by diurnally vertical migrants at depth was relatively important for downward flux via zooplankton community in the areas and seasons with low zooplankton biomass.
