Abstract: | Microbiological parameters were examined in the surface microlayer (150 μm) and the subsurface waters (1 m) of the Fraser River estuary (British Columbia) at salinities of 0, 15 and 25‰. Little difference was observed in the neustonic variables between these three stations. A comparison of the neuston with the plankton over the estuary as a whole revealed elevated detritus, particulate organic carbon and nitrogen but reduced ATP, heterotrophic activity and percentage respiration in the neuston. Enrichment of bacterial numbers or dissolved organic carbon was not observed in the surface microlayer. |
