A record of deep-ocean dissolved O2 from the oxidation state of iron in submarine basalts

Abstract

The oxygenation of the deep ocean in the geological past has been associated with a rise in the partial pressure of atmospheric molecular oxygen (O 2) to near-present levels and the emergence of modern marine biogeochemical cycles. It has also been linked to the origination and diversification of early animals. It is generally thought that the deep ocean was largely anoxic from about 2,500 to 800 million years ago, with estimates of the occurrence of deep-ocean oxygenation and the linked increase in the partial pressure of atmospheric oxygen to levels sufficient for this oxygenation ranging from about 800 to 400 million years ago. Deep-ocean dissolved oxygen concentrations over this interval are typically estimated using geochemical signatures preserved in ancient continental shelf or slope sediments, which only indirectly reflect the geochemical state of the deep ocean. Here we present a record that more directly reflects deep-ocean oxygen concentrations, based on the ratio of Fe 3+ to total Fe in hydrothermally altered basalts formed in ocean basins. Our data allow for quantitative estimates of deep-ocean dissolved oxygen concentrations from 3.5 billion years ago to 14 million years ago and suggest that deep-ocean oxygenation occurred in the Phanerozoic (541 million years ago to the present) and potentially not until the late Palaeozoic (less than 420 million years ago).

  • Biospheric O2 must have risen to something like modern levels much later, particularly in the deep ocean, and pulsed oxygenation in an ocean that was still mostly anoxic may have continued even into the Paleozoic.

    “The natural corollary in this discussion is that biospheric O2 must have risen to something like modern levels much later (Dahl et al., 2010; Lu et al., 2018), particularly in the deep ocean (Stolper and Keller, 2018), and that pulsed oxygenation in an ocean that was still mostly anoxic may have continued even into the Paleozoic.”

  • Deep-ocean [O2] reconstructed from the iron redox chemistry of extrusive, subaqueous volcanic rocks is consistent with low-oxygen conditions, though this record also allows for pervasive deep-ocean anoxia.

    “Evidence for low-oxygen conditions is consistent with deep-ocean [O 2 ] reconstructed from the iron redox chemistry of extrusive, subaqueous volcanic rocks, though this record also allows for pervasive deep-ocean anoxia (Stolper & Keller 2018), and the eruption depths of these rocks are not always well constrained.”

  • There is a striking coincidence between the emergence of deep rooting systems during the Silurian-Devonian transition (∼410-390 Mya) and an increase in the proportion of marine sedimentary rock samples deposited under oxygenated waters.

    “In particular, there is a striking coincidence between the emergence of deep rooting systems during the Silurian-Devonian transition (∼410-390 Mya) and an increase in the proportion of marine sedimentary rock samples deposited under oxygenated waters (Dahl et al. 2010, Sperling et al. 2015, Stolper & Keller 2018).”

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.
