isotope interpretation 1 should be P_isotope? and move "precipitation amount" to climate fields. -BK

"Hereinafter, we focus only on the results for n-C26 as these consistently had the highest, most evenly-shaped peaks and the peaks were present in the most samples."- Terwilliger et al., 2013; ISO2k name: SL13TEAK
dDn-C26 data unambiguously if perhaps qualitatively reflect changes in precipitation despite potentially confounding influences of vegetation type and other factors. "The dD values of the fatty acids from land-plant sources (n-C26, n-C28, n-C30) were significantly correlated to one another in each site"
precipitation occurs in closest proximity to the bulk of global cloud formation and its dD values are most influenced by its amount. dD values de- crease as precipitation amount increases (Risi et al., 2008). Additional factors shape the dD values of fatty acids in land-plants as well but their consideration below suggests that our dDn-C26 sequences were unambiguously if qualita- tively reflecting changes in amount of precipitation.
Plant to plant differences in fractionations between dD values of n-alkyl compounds and their precipitation source may introduce the greatest error in interpreting rainfall amount.

fraction of modern 14C activity uncertainty
210Pb, 239+240Pu or 137Cs activity uncertainty
Y if supported 210Pb activity, N if unsupported 210Pb activity
model used to convert 210Pb activity to age (e.g., constant rate of supply)
years before 1950 (calibrated age, or ages that dont need calibration)
Study includes 2 other sites which do not meet Holocene age criteria. dDn-C26 is the primary variable used for precipitation interpretation
