Extended Data Fig. 5: Active layer thickness versus fMAOC.
From: Dominance of particulate organic carbon in top mineral soils in cold regions

Relationship between active layer thickness and proportion of MAOC relative to SOC (fMAOC). Line and shading represent linear regression and 95% confidence intervals (fMAOC = 0.33 + 0.0014 × Active layer thickness, n = 133, R2 = 0.09, P = 0.031). The panel corresponds to the first 30 cm of mineral soil.
