Denitrification and anammox activity in Arctic marine sediments
Open accessAbstract
We measured rates of N2 production through anaerobic NH 4+ oxidation with NO 2−(anammox) and denitrification in permanently cold (from −1.7°C to 4°C) sediments off the east and west coasts of Greenland. The investigated sites (36– to 100–m water depth) covered sediments in which carbon contents ranged from 0.3 to 3.2 dry weight %, O 2 uptake rates ranged from 3.4 to 8.3 mmol m−2 d−1, O 2 penetration depths ranged from 0.25 to 1.70 cm, and bottom‐water NO 3−concentrations ranged from 0.3 to 15.3 µmol L−1. Total N 2 production was 34–344 µmol N m−2 d−1, of which anammox accounted for 1–92 µmol N m−2 d−1 (1–35% of total) and denitrification for 33–265 µmol N m−2 d−1. At one of the high‐Arctic sites, anammox activity had an optimum temperature (Topt) of 12°C, while that of bacterial denitrification was 24°C. According to the classical temperature scheme for metabolic growth, the anammox response was psychrophilic, while denitrification was psychrotrophic. Although Topt was considerably higher than in situ temperatures, rates of denitrification and anammox were still high at −1.3°C, reaching 17% and 40%, respectively, of those found at Topt. The activation energies, Ea, of anammox and denitrification were 51.0 and 60.6 kJ mol−1, respectively, and the corresponding Q10 values were 2.2 and 2.4. Rates of anammox were linearly correlated with bottom‐water NO 3−concentrations (r2 = 0.96, p < 0.0001, n = 11) at the investigated sites. We suggest that the slow‐growing anammox bacteria are favored in sediments with high and stable NO 3−conditions. This may be a general pattern in deeper waters at other latitudes as well.

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.
