Supplement. This supplement includes dendrograms from the cluster analysis of water mass hydrographic properties (Fig. S1) and mean seasonal profiles of temperature, salinity, sigma-t and chlorophyll fluorescence (Fig. S2). Additional information includes CHEMTAX output of chl a to pigment ratios for different phytoplankton groups and water mass types (Table S1), pigment to total accessory pigment ratios for different seasons and water mass regimes (Table S2), CHEMTAX-derived contributions to chl a by taxonomic groups of phytoplankton (Table S3), and eigenvectors for the PCA analysis for the different water mass types (Table S4).

Choice of initial ratios
The taxonomic groups considered for the analysis were based on prior knowledge of phytoplankton in the region (Dortch & Whitledge 1992, Redalje et al. 1994, Bode & Dortch 1996, Lohrenz et al. 1999, Chen et al. 2000, Jochem 2003, Qian et al. 2003, Wawrik et al. 2003, Dagg et al. 2004, Wawrik & Paul 2004, Wysocki et al. 2006) and limited microscopic analyses during the cruises. Initial ratios selected for the relevant taxonomic groups were from values provided in previous studies (Gieskes & Kraay 1986, Jeffrey et al. 1997, Mackey et al. 1998, Schlüter et al. 2000, Schlüter & Møhlenberg 2003, Latasa et al. 2004, Veldhuis & Kraay 2004, Zapata et al. 2004, Rodríguez et al. 2005, Laza-Martinez et al. 2007, Seoane et al. 2009). Pigment ratios were also determined for selected phytoplankton taxa (Thalassiosira spp., Skeletonema spp., Nitzschia spp., Phaeodactylum spp., Dunaliella sp., and Isochrysis spp.) maintained in batch culture (FCRG medium, described in Eppley et al. 1967, 20oC, 12:12 light:dark cycle).
