Table 1 Environmental parameters. The samples observed at the center (C) and the peripheral (P) sites during early- (stage I) and mid- (stage II) stationary phase of the bloom. Abbreviations: Temp, temperature; DO, dissolved oxygen; Chl a, chlorophyll a; DOC, dissolved organic carbon; DON, dissolved organic nitrogen; TPA, total prokaryotic abundance; N.D., not detectable
