Thus, for the past ~5000 years of sedimentation, the n- alkanes in Hakluytvatnet (including short-, mid-, and long-chain homologues) derive predominantly from aquatic moss, and their dD values therefore reflect that of lake water.

Competing influence of polar and maritime airmasses

The hydrogen isotopic composition (D/H; dD using the delta notation) of leaf wax n-al- kanes reflects the D/H of source water used by a plant after modification by evaporation and biosynthetic fractionation (Kahmen et al., 2013a,b; Sachse et al., 2004, 2012), and therefore is useful for paleohydrologic reconstructions. The movement of water through the hydrologic cycle (Dansgaard, 1964), as well as regional and seasonal climatological conditions (Bowen and Revenaugh, 2003), results in variations of stable isotopes (D/H and 18O/16O) of local precipitation. Algae and macrophytes incorporate hydrogen from lake water while terrestrial plants use hydrogen from soil moisture; both water sources are ultimately derived from local precipitation. Therefore, dD of different n-alkanes can be used to reconstruct the climatic factors controlling the isotopic composi- tion of lake water and precipitation (Balascio et al., 2013; Rach et al., 2014).
