Chlorophyll b occurred in 47% of the samples analyzed and the dominant chlorophyll a degradation product was phaeophorbide a. Chlorophyll a was usually found at low concentrations and phaeophytin a levels were undetectable. Concentrations of the various chlo- rophylls and their degradation products were used to infer changes in taxonomic composition, phyto- plankton biomass and zooplankton grazing pressure across several frontal zones.
