Fig. 2: Comparing model-generated PE with literature data.

a,b, Data generated for 1,450 model runs in a Monte Carlo approach (transparent black dots) for the conventional approach to calculate PE of POC that considers only POC (a) and for the newly defined PE that considers both POC and MOC (b). These are compared with field data from previous studies12,36. The spread of model data is derived from a normal distribution of the net sediment accumulation rate data observed in the global grid datasets (Supplementary Figs. 1 and 2). The envelope line (dashed line) represents the general boundaries of the spread of data identified in previous studies13,41. Low BW O2 stands for low bottom water oxygen concentration.
