Dinitrogen fixation across physico‐chemical gradients of the Eastern Tropical North Pacific oxygen deficient zone


"The Eastern Tropical North Pacific (ETNP) Ocean hosts one of the world's largest oceanic oxygen deficient zones (ODZs). Hotspots for reactive nitrogen (Nr) removal processes, ODZs generate conditions proposed to promote Nr inputs via dinitrogen (N2) fixation. In this study, we quantified N2 fixation rates by 15N‐tracer bioassay across oxygen, nutrient and light gradients within and adjacent to the ODZ. [...]"
