We simultaneously studied microbial-mediated carbon fluxes at 2 contrasting siteswithin the coastal upwelling system off Galicia, near A Coruña and Vigo, Spain, over an annualcycle in order to compare the fraction of primary production released as dissolved organic carbon(DOC) and the degree of coupling between bacteria and phytoplankton. A significant fraction ofprimary production was released as DOC at both sites, averaging ~30%. DOC release ac countedfor, on average, 30% of the total bacterial carbon demand, which is indicative of a moderatetrophic dependence of bacteria on phytoplankton in these coastal ecosystems. Nevertheless, differencesin hydrographic conditions associated with stronger upwelling pulses off Vigo, anddeeper upper mixed layers during the downwelling period off A Coruña, led to significant differencesin phytoplankton dynamics and the subsequent direct coupling with heterotrophic bacteria.Strong direct coupling between phytoplankton extracellular release and bacterial production (BP)was found off Vigo, which could be related to the quality of the DOC produced by actively growingphytoplankton. By contrast, DOC release and BP rates were decoupled off A Coruña, likelydue to unaccounted DOC associated with indirect trophic processes or to the low availability offreshly produced exudates associated with overflow or photoinhibition mechanisms.RADIALES (IEO), DIFUNCAR (CTM2008-03790/MAR)Versión del editor2,483
