Sedimentary nitrogen isotopic ratio as a recorder for surface ocean nitrate utilization
Abstract
In two contrasting regions of the ocean, the equatorial Pacific and the southern ocean, the δ 15 N of core top sediments were strongly related to [NO 3 − ] in surface waters. With distance from the equator in the equatorial Pacific, δ 15 N increased from 7‰ to 16‰ as [NO 3 − ] decreased from 8μM to < 0.1 μM. Going from 60° to 30° S in the SE Indian Ocean, core top δ 15 N increased from 5‰ to 11‰ as surface [NO 3 − ] decreased from 25μM to < 0.1 μM. These results are strong evidence that sedimentary δ 15 N in these regions is recording the increasing isotopic enrichment of near‐surface NO 3 − with its depletion by phytoplankton. In the case of the equatorial Pacific, δ 15 N values for sinking particles collected at 150 m matched well the core top sediment values, demonstrating little diagenetic alteration of the near‐surface generated isotopic signal. These equatorial Pacific data sets have variations with near‐surface [NO 3 − ] consistent with Rayleigh fractionation kinetics for a fractionation factor (ϵ u ) of 2.5‰. This value is substantially lower than previously found for temperate or polar regions, perhaps as a result of differences in phytoplankton species assemblage or growth condition. In the southern ocean south of the polar front, comparison of δ 15 N values for opal‐rich sediments south and sinking particles indicates an apparent +5‰ diagenetic enrichment relative to the surface‐generated signal that requires further investigation. This exception aside, our observations show that the surface‐water relationship of increasing δ 15 N with increasing NO 3 − depletion is generally transmitted to and preserved in the sediments, an important requirement for further development and application of this important paleoceanographic tool.

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.
