Nature Communications, Published online: 02 May 2026; doi:10.1038/s41467-026-72049-9 Sedimentation processes in the Japan Trench control seafloor residence of organic carbon, shaping its subsurface degradation and burial. These processes may influence how much carbon is ultimately transferred from Earth’s surface into subduction zones.
