Ferruginous conditions: a dominant feature of the ocean through Earth's history

Abstract

The reconstruction of oceanic paleoredox conditions on Earth is essential for investigating links between biospheric oxygenation and major periods of biological innovation and extinction, and for unravelling feedback mechanisms associated with paleoenvironmental change. The occurrence of anoxic, iron-rich (ferruginous) oceanic conditions often goes unrecognized, but refined techniques are currently providing evidence to suggest that ferruginous deep-ocean conditions were likely dominant throughout much of Earth's history. The prevalence of this redox state suggests that a detailed appraisal of the influence of ferruginous conditions on the evolution of biogeochemical cycles, climate, and the biosphere is increasingly required.

  • Iron would have been much more abundant in surface waters on a more reducing early Earth when basic microbial metabolic machinery was being established.

    “By contrast, iron would have been much more abundant in surface waters on a more reducing Earth when basic microbial metabolic machinery was being established (e.g., Poulton and Canfield, 2011;David and Alm, 2011).”

  • Poulton and Canfield (2011) suggest oceans were dominantly ferruginous until the late Archean, after which a surface oxic layer likely formed.

  • Fe speciation analyses have shed new light on spatial complexity of water column redoxclines and shown the Proterozoic was likely dominated by ferruginous conditions.

    “Fe speciation analyses have shed new light on the spatial complexity of water column redoxclines (e.g., Poulton et al., 2010), and have shown that the Proterozoic was likely dominated by ferruginous conditions (Planavksy et al., 2011;Poulton and Canfield, 2011).”

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.
