4.2 Nitrogen Species
The vertical profiles of nitrate, nitrite and ammonium in the center of the
western gyre (Knorr 2003; April 2003; Leg 8; Stn 7) are shown versus density
in Fig. 7. Oxygen and sulfide are shown on the left for ease of comparison
with boundaries of the suboxic zone. Nitrate is depleted at the surface due to
