Ammonium and nitrite oxidation at nanomolar oxygen concentrations in oxygen minimum zone waters
Open accessAbstract
Significance: As an essential nutrient, nitrogen plays a critical role in regulating oceanic primary productivity. Nitrogen is cycled between bioavailable and nonavailable forms through a network of aerobic and anaerobic microbial processes. Expanding oxygen minimum zones are hot spots for such transformations. Using a highly sensitive oxygen-sensing technique, we demonstrate that two key aerobic processes, ammonium oxidation and nitrite oxidation, persist even at low oxygen levels of 5–30 nM (∼0.01% air saturation). Activity at these low oxygen concentrations allows ammonium and nitrite oxidation to persist at oxic/anoxic boundaries and within anoxic waters if oxygen intrudes at sufficient frequency. In such environments, ammonium and nitrite oxidizers compete with anaerobic organisms for ammonium and nitrite, and thus act to control nitrogen loss.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
