The main studied processes of the N cycle in different marine environments. Every coloured arrow represents a N transformation: N 2 fixation (red), nitrification (light blue), nitrate reduction (violet), DNRA (magenta), denitrification (aquamarine), N-damo (green), and anammox (orange). Black curved arrows represent physical processes such as advection and diffusion.
