      All profiles showed that ΣNO x was depleted at the surface with a nitracline located at about 20–40 m depth, below which ΣNO x increased to about 30 μM. The location of the nitracline coincided with a NO 2 - concentration peak of 0.6 μM at 30 m, which was also the upper boundary of the O 2 minimum (29 μM after 60 m) extending down to 160 m.
