Mesozooplankton ingestion rates on autotrophs from SEPT-1999 WP-2 closing net stations

Gut fluorescent content of dominant copepods (ng Chl-a ind-1), was measured according to the method described by Mackas and Bohrer (1976), as modified by Morales et al. (1990). The samples of mesozooplankton were deep-frozen for the measurements of gut fluorescence of copepods. The gut evacuation rate was calculated according to Dam and Peterson (1988). Ingestion rates (ng chl_ cop-1 h-1) were estimated by applying gut clearance rate to the gut pigment contents.
