Extended Data Fig. 2: Peat core CEN-17.4 bulk organic and plant wax data.
From: Hydroclimatic vulnerability of peat carbon in the central Congo Basin
a, Total organic carbon (TOCEA) and total nitrogen (TN). b, Carbon-to-nitrogen ratios (C/N). c, Carbon Preference Index (CPI). Note that the marked decrease in CPI during the Ghost Interval supports the increase in decomposition95,96. d, Carbon isotopes of long-chain n-alkanes (δ13Cn-alkane). e, Hydrogen isotopes of long-chain n-alkanes (δDn-alkane). Error bars based on replicate analyses represent the 1σ uncertainty and are often too small to distinguish from the lines. Horizontal brown band bounded by dashed lines denotes the Ghost Interval.
