Table 2 Relative abundance of Nitrospina reads, functional genes from Nitrospina, and Prochlorococcus reads (all expressed per million reads) within metagenomes collected on the edge of the oxygen minimum zone (OMZ), in the secondary chlorophyll maximum (SCM), and in the secondary nitrite maximum (SNM) at Stations 1–3.
From: Substantial oxygen consumption by aerobic nitrite oxidation in oceanic oxygen minimum zones
