Short summary

We investigated the light response of field Trichodesmium N₂ fixation and net dissolved nitrogen release behavior. Our results suggest that N₂ fixation was a function of light intensity, and the light requirement of Trichodesmium nitrogen fixation was high relative to its photosynthetic light demand. Meanwhile, light is a crucial parameter driving the physiological state of Trichodesmium, which subsequently determined the C / N metabolism and net dissolved nitrogen release.
