Short summary
Trichodesmium is significant marine N2 fixer. We conducted short- and long-term UV exposure experiment to investigate how UV affects this organism. Our results showed N2 fixation and carbon fixation rates were significantly reduced under UV radiation. As a defense strategy, Trichodesmium is able to synthesize UV-absorbing compounds to protect from UV damage. Our results suggest that shipboard experiments in UV-opaque containers may have substantially overestimated in situ N2 fixation rate.
