Abstract

The Third Way: Because organic carbon contains a larger fraction of the light isotope 12 C than inorganic carbonate, variations in the carbon isotopic record of sedimentary rocks are thought to represent changes in the amount of organic carbon buried as sediments (and thus removed from the rest of the carbon cycle). Schrag et al. (p. 540 ; see the Perspective by Canfield and Kump ) suggest that historically a third component was important: authigenic carbonate. Authigenic carbonate is not produced in any appreciable quantity today, but was much more abundant when the level of atmospheric oxygen was low.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Periods of low atmospheric oxygen and widespread marine anoxia in past climates have been favorable for the formation of abiotic authigenic carbonates in marine sediment pore fluids, representing a significant carbon sink.

  • Diagenesis can change carbonate δ13C, δ18O, and trace element contents, which restricts their reliability as paleoenvironmental proxies.

    “These processes can alter carbonate δ 13 C and δ 18 O, as well as the trace element compositions (e.g., Schrag et al., 2013;Swart and Kennedy, 2012), limiting their use for paleoenvironmental proxies.”

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.
