Holocene and LGM deep-ocean TOC burial (MAR) estimated for the different province maps (shown in Supplementary Fig. 2). A subdivision of the provinces following the 1,500 m isobath was added for province maps 5 and 7. The glacial excess burial was calculated between 80ka, when global burial diverged from MIS5 values, and 10ka, when global burial reached low Holocene values (Fig. 1).
