Caption

Relative plate motions and plate boundary geometries are from Cao et al. (2024), with plate motions placed in a mantle reference frame. Continents are light grey, with continental margins shown in medium grey. Passive continental margins (continental shelves) are marked by thin, light blue lines. The intensity of volcanic carbon outgassing from mid-ocean ridges is red (low) to yellow (high). Dark blue to light pink oceanic background colours represent oceanic crustal carbon storage.
