Flux and Isotopic Composition of Sedimentary Carbon Subducting Along the World's Trenches

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Here we provide comprehensive estimates for the subducted sedimentary flux of inorganic and organic carbon and δ13C at 16 trench segments worldwide. Our calculations provide minimum (incoming sediment), maximum (trench fill) and best estimates (underthrust) of carbon fluxes.
