Figure 4

Results from source apportionment (Markov Chain Monte Carlo simulations) based on δ13C, Δ14C and lignin concentration. The source classifications were: Marine OC (MarOC; blue), PF-ICD (teal) and PF-Active-layer (yellow). Upper x axis shows the core depth (cm) and lower x axis shows the age (cal yBP). Bars and whiskers display mean and s.d. of the relative contributions from each source based on the Monte Carlo simulations.
