Short summary
Short summary
We present taxon-specific niche zonation of nitrogen-fixing (diazotrophic) microbes in the East China Sea. We show spatiotemporal variations in the distribution and activity of diazotrophic ecotypes that are highly correlated with distinct water masses. The realized niche partitioning underscores the link between diazotrophic biogeography and physicochemical gradients created by complex land-ocean interactions, which are primarily affected by the Kuroshio intrusion and the East Asia monsoon.

Short summary
Short summary
N2 fixation by marine diazotrophs is an important bioavailable N source to the global ocean. This updated global oceanic diazotroph database increases the number of in situ measurements of N2 fixation rates, diazotrophic cell abundances, and nifH gene copy abundances by 184 %, 86 %, and 809 %, respectively. Using the updated database, the global marine N2 fixation rate is estimated at 223 ± 30 Tg N yr−1, which triplicates that using the original database.

Short summary
We report taxon-specific biogeography of N2-fixing microbes (diazotrophs) driven by Kuroshio intrusion (Kl) into the South China Sea. We show that the composition and distribution of distinct diazotrophic taxa shift with Kl-induced variations in physicochemical parameters of seawater and that Kl shapes diazotrophic community primarily as a stochastic process. This study thus has implications for the distribution of diazotrophs in a future warming ocean, as Kls are projected to intensify.
