Vertical distribution of phytoplankton communities in open ocean: An assessment based on surface chlorophyll

Abstract: [ 1 ] The present study examines the potential of using the near-surface chlorophyll a concentration ([Chla ] surf ), as it can be derived from ocean color observation, to infer the column-integrated phytoplankton biomass, its vertical distribution, and ultimately the community composition. Within this context, al arge High-Performance Liquid Chromatography (HPLC) pigment database was analyzed. It includes 2419 vertical pigment profiles, sampled in case 1w aters with various trophic states (0.03-6 mg Chla m À… Show more

“…Except for Nodosinum 2, the concentration of 19-hex is either much lower than fucoxanthin or not present in all samples which shows that diatoms were the primary pigment source. This is supported by the global relationship between fucoxanthin and chlorophyll a of 1.41 for living diatoms and between 19-hex and chlorophyll a of 1.27 for haptophytes (see Uitz et al, 2006). After chlorophyll a and pheophorbide a, fucoxanthin and pheophytin a were the most abundant.…”

“…Pico-sized phytoplankton, and particularly cyanobacteria, dominated the total phytoplankton abundance and biomass (< 20 lm) of the stratified southern region, consistent with evidence for the importance of this size class for the production in warm, low nutrient waters (Partensky et al 1996;Maranon et al 2000;Perez et al 2006;Uitz et al 2006). Prochlorococcus was the main photosynthetic prokaryotic group, with the northern edge of its distributions closely matching Table 2.…”

“…In contrast, pigment analysis with CHEMTAX provides information regarding taxonomic composition including larger-sized algae that are typically missed by FCM, but lacks information regarding cell abundances and is unable to differentiate size differences within taxonomic groups (Uitz et al 2006(Uitz et al , 2008. These differences between CHEMTAX and FCM analysis became apparent when comparing depth-integrated Chl a Fig.…”

“…Seven diagnostic pigments (DP) were used to divide the phytoplankton population quantitatively, relative to the TChla concentration, into three main size classes: picophytoplankton, nanophytoplankton and microphytoplankton using the following 4 equations according to Uitz et al (2006): Concentrations were integrated throughout the depth strata corresponding to that sampled for tintinnids. The size fractionated Chla concentrations (pico, nano and micro) transformed into % total chlorophyll were used to estimate an index of the size-diversity of chlorophyll (Shannon index, lnbased).…”
