Comment:
Stable carbon isotope composition (weighted mean) of C29-C31 n-alkanes from Mfabeni, reflecting changes in C3/C4 vegetation type. Hydrogen isotope composition (weighted mean) of C29-C31 n-alkanes from Mfabeni, reflecting changes in precipitation amount and ET. dDcor is the dDwax corrected for ice volume changes. The errors on the isotope data reflect analytical uncertainty of duplicate analyses. Paq at Mfabeni, indicating the amount of aquatic vs. terrestrial n-alkanes (high/low water table).
