Particle fluxes to deep sea

It is obvious that while the total PP is quantitatively similar during the NEM and SWM, the quality of production and the food web structure should be very different during the two seasons. Naqvi etal. (2002) argued that a deficiency of Si044- relative to NO/ (reflecting the concentrations of these nutrients at the 

then the nano- and microzooplankton stocks in turn should be sustained by the availability of either heterotrophic bacteria (growing on labile DOC) or pico-plankton that make use of the regenerated nutrients. Significantly, the abundances of both pico-autotrophs (primarily Prochloro-coccus) and heterotrophic bacteria are close to their maxima during the SI, and this perhaps ensures enough carbon supply for other constituents of the microbial food chain.
