Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • The total pressure at 2.7 Ga was 0.23 ± 0.32 bar as inferred from gas bubbles in basaltic lava flows by Som et al. (2016).

    “The grey lines indicate the total pressure at 2.7 Ga of 0 . 23 ± 0 . 32 bar as inferred from gas bubbles in basaltic lava flows by Som et al. (2016).”

  • The cold trap might not have existed continuously during the Archean eon due to fluctuations to very low total atmospheric surface pressures.

    “The cold trap, however, might not have existed continuously during the Archean eon due to fluctuations to very low total atmospheric surface pressures (Som et al. 2016; Lammer et al. 2018; St¨ ueken et al. 2020.”

  • Vesicle volumes in 2.7-Ga-old basaltic lava flows erupted at sea level imply a 0.23 ± 0.23-bar (2σ) paleopressure.

    “Third, vesicle volumes in 2.7-Ga-old basaltic lava flows erupted at sea level imply a 0.23 ± 0.23–bar [2σ] paleopressure (56).”

    From The Archean atmosphere (2020) · cites this paper as [56]

  • These data have been used to argue that Archean N2 was sequestered into solid phases after an early advent of biological nitrogen fixation.

    “Marine phyllosilicates at 3.8 Ga ago are ammonium enriched (146, 147), which probably came from porewater ammonium (NH4+) derived from degraded organics (Table 1) (148, 149), and these data have been used to argue that Archean N2 was sequestered into solid phases after an early advent of biological nitrogen fixation (56, 150).”

    From The Archean atmosphere (2020) · cites this paper as [56]

  • N2 likely was outgassed and built up during the Archean eon and became the main atmospheric species besides CO2.

    “N 2 likely has been outgassed and built up during the Archean eon (Mikhail and Sverjensky 2014; Som et al. 2016; Lammer et al. 2018; Lammer et al. 2019; St¨ ueken et al. 2020; Sproß et al. 2021), and became the main atmospheric species besides CO 2 .”

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.
