Phytoplankton community composition determined through analysis of pigments using HPLC
Progress Code: completed Statement: For Incubation 3 (ENRICH064, CTD 15) a proportion of chlorophyll that was classified by CHEMTAX as dinoflagellates was observed to be haptophytes using light microscopy.These groups share similar pigments and can therefore be difficult to separate using CHEMTAX, p...
