Abstract: In the South China Sea (SCS), the southwest (SW) monsoon between June and September induces coastal upwelling off southern central Vietnam. This thesis includes the first ground truth evaluation of the primary productivity of this upwelling zone, as well as an assessment of the importance of nitrate and pelagic dinitrogen (N<sub>2</sub>) fixation in fueling the productivity. Further, it was shown that Mekong River discharge sets favorable nutrient conditions for diazotrophs, which supports the hypothesis that discharge by tropical rivers might generally enhance oceanic N<sub>2</sub> fixation.
