Fluxes of volatiles (H2O, CO2, N2, Cl, F) from arc volcanoes

Abstract

This review gives an overview of the estimates of volatile emissions from arc and mid-ocean ridge volcanoes to the atmosphere and hydrosphere with particular focus on H2O, CO2, N2, Cl and F. The gas compositions of high temperature (>500°C) fumaroles are compiled and used to derive magmatic H2O/SO2, CO2/SO2, HCl/SO2 and HF/SO2 ratios on an arc-by-arc basis to obtain new estimates of major volatile fluxes from arcs globally. The estimate of F flux from arcs is two orders of magnitude smaller than the amount of F released from mid ocean ridges whereas the arc Cl flux exceeds the ridge flux. An important observation is that globally the water budget of subduction zones seems to be balanced and the amount of water degassed through arc volcanism is within the estimates of the amount of water released from the slab below the volcanic front. Recent work that focused on the Central American arc shows that detailed knowledge of the subduction input compositions, coupled with gas emission studies is critical to further constrain the fate of volatiles during the subduction processes.

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

  • Other outgassing estimates are 7 × 10^10 mol N year−1 from arcs.

    “However, other outgassing estimates are 7 × 1010 mol N year−1 from arcs (157) or 9 ± 4 × 1010 mol N year−1 globally [(64), p. 204], such that current source and sink N fluxes balance within uncertainties.”

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.
