Revisiting the distribution of oceanic N2 fixation and estimating diazotrophic contribution to marine production
Marine N2 fixation supports a significant portion of oceanic primary production by making N2
bioavailable to planktonic communities, in the process influencing atmosphere-ocean
carbon fluxes and our global climate. However, the geographical distribution and controlling
factors of marine N2 fixation remain elusive largely due to sparse observations. Here we
present unprecedented high-resolution underway N2 fixation estimates across over 6000
kilometers of the western North Atlantic. Unexpectedly, we find increasing N2 fixation rates …
