Abstract:Subtropical‐subpolar transition water is a potential domain for N2 fixation, but the understanding of N2 fixation in such waters remains incomplete. We simultaneously examined the N2 fixation activity and community structures of diazotrophs and all prokaryotes from the surface to just above the seafloor off Patagonia in the transitional region of the eastern South Pacific Ocean. N2 fixation activity was not detected in the surface waters, but was observed sporadically and only in subpolar bathypelagic waters (… Show more
