Table 2. Selected examples of phytoplankton size fractions and/or taxonomic composition in different areas of the MS. Values have been rounded to the first decimal digit. Abbreviations: SL for Surface Layer, DCM for Deep Chlorophyll Maximum, DI for Depth Integrated, C for Carbon, HPLC for pigment-based group discrimination, Dino. for dinoflagellates, Prymn. for prymnesiophytes, Pelago. for pelago- phytes, Crypto. for cryptophytes, Chromo. for nanoflagellates containing 19 –HF and/or 19 –BF, Nano. for nanoplankton, Cocco. for coccolithophores, Synecho. for Synechococcus, Prochloro. for Prochlorococcus. The values reported in Refs. 1, 3, 7 and 9 are derived from figures in the respective papers. 2 :
