Fig. 6: Soil carbon changes over time and depth.
From: Alaskan carbon-climate feedbacks will be weaker than inferred from short-term experiments

The panels show the depth-dependent changes in soil carbon (gC m−2) over time at each site. Red represents inputs of SOC, while blue indicates depths where soil organic carbon is lost. Note, the color-bar axes denoting changes in soil carbon differs from site to site.
