Abstract

Air pollution creates high Fe solubility in pyrogenic aerosols, raising the flux of biologically essential Fe to the oceans.

  • Large amounts of industrial, urban and wildfire pyrogenic and acid aerosols are being globally deposited in the ocean.

    “Studies have shown that large amounts of industrial, urban and wildfire pyrogenic and acid aerosols are being globally deposited in the ocean (Ito et al., 2019;Rodríguez et al., 2021;Tang et al., 2021;Hamilton et al., 2022).”

    The Results and Discussion section (page unavailable) models combustion-derived iron deposition to the ocean, including a global-mean contribution of 2.6–7.1% of total iron deposition, and discusses biomass-burning and coal-combustion sources. The paper discusses acid processing of aerosols, but the cited passages do not establish that large amounts of acid aerosols themselves are deposited globally in the ocean; the deposition estimates concern iron, not aerosols as a whole.

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.
