Figure 1: Comparison of C pools between the active layer and permafrost deposits.
From: Determinants of carbon release from the active layer and permafrost deposits on the Tibetan Plateau

The sub-panels correspond to the relative sizes of the fast C pool (a–e), the slow C pool (f–j) and the passive C pool (k–o) of the active layer (AL, red notched box) and permafrost deposits (PF, blue notched box) at five study sites including Youyun (YY) and Changmahe (CMH) in Maqin County, Huashixia (HSX) in Maduo County , Wenquan (WQ) in Xinghai County and Kunlunshankou (KLSK) in Geermu—see Supplementary Fig. 1 for locations. An asterisk indicates significant differences between the two layers. The whiskers illustrate the 5th and 95th percentiles, the ends of the boxes represent the 25th and 75th quartiles (interquartile range), and the notches represent the 95% confidence intervals.
