Significant Pearson's correlation coefficient between environmental and biological parameters over the annual cycle at P < 0.05 after Bonferroni correction. SCORE1 and SCORE2 are the scores on the first two axes of the free-living bacterial community obtained by T-RFLP fingerprinting after principal component analysis

	Date	PO4	NO3	NH4	TN	Prot	PHAEO	BA_FL	BETA	VmaxBGase	VmaxLAPase	VmaxAPase

PO4, inorganic phosphorus concentration; NO3, nitrate concentration; NH4, ammonium concentration; TN, total nitrogen; Prot, dissolved proteins concentration; PHAEO, total Phaeocystis cells; BA_FL, free-living bacterial abundance; BETA, abundance of Betaproteobacteria, VmaxBGase, VmaxLAPase; VmaxAPase, maximum enzymatic rate for Betaglucosidase, Leucine-aminopeptidase and Alkalino-Phosphatase, respectively.
