Figure 3. Spatial distribution of pigments along the sampling transect in North Pacific.

(A) Pigments that correlated the most with the phytoplankton abundances: alloxanthine, zeaxanthin, divinyl chlorophyll a (DVChl a), divinyl chlorophyll b (DVCHl b), and lutein. (B) Total chlorophyll a (Chl a). Stations (Station 1, Station 2, and Station 3) with sampling sites as CTD casts and corresponding depths (the surface layer (S), deep chlorophyll maximum (DCM), and mixed layer depth (MLD)) are shown on x-axis. Concentrations of pigments (µgL ⁻¹) are shown on y-axis (log-scale at (b)).
