Figure 3: Distribution of 14C and 13C isotopes and end-member contributions across the fluvial network.

From: Utilization of ancient permafrost carbon in headwaters of Arctic fluvial networks

Figure 3

(a) Initial (open squares) and utilized (black circles) Δ14C and δ13C values of DOC. Isotopic ranges of three contributing carbon sources are shown in red boxes (see Methods). (b) Mean percent (±s.e.m.) contribution of each carbon source to the DOC utilized over bioincubations (DOCloss) in waters from differing site types.
