Correlation matrix (Pearson r) between environmental variables, T (temperature), S (salinity), DOC, DON, NO−3 (nitrate), PO3−4 (phosphate), Total Chl (total chlorophyll a), log10 transformed HNA, LNA, Live, CTC+ bacteria, LF Syn (Low fluorescence Synechococcus), HF Syn (High fluorescence Synechococcus), V1, V2, V3 and HNF abundances. Only significant values (*P < 0.05, **P < 0.01 and ***P < 0.001) are included here, n = 44–51.
