Resumo: | Spatial and temporal estimates of bacterial numbers, biomass, activity and production were measured in the S. Benguela upwelling system during the course of a phytoplankton bloom. Bacterial numbers and biomass were highest in the euphotic zone and correlated closely with particulate carbon in the water column rather than with chlorophyll a concentrations. 3H-Thymidine incorporation gave good estimates of production. Differential utilisation of photosynthetic exudates and detrital POC by bacterioplankton during the course of a bloom might account for the varying significance ascribed to exudates and POC as a source of carbon for bacterial production.
