Abstract: | Addition of chelated iron at concentrations of 0.5, 1.0, 10 and 100μg Fe·l?1 to Sargasso Sea phytoplankton assemblages did not affect the rate of photosynthesis during 4-h incubation experiments. In experiments with 72-h incubations, however, iron enhanced carbon assimilation. The enhancement was independent of iron concentration. |
