Molecular distributions of terrestrial biomarkers were investigated in fresh snow samples from Sapporo, northern Japan, to better understand the long-range atmospheric transport of terrestrial organic matter by the Asian winter monsoon. Stable carbon (δ 13 C) and hydrogen (δD) isotope ratios of C 22 –C 28 n-alkanoic acids were also measured to decipher their source regions...
Compound-specific carbon isotope ratios (δ 13 C) of leaf wax n-alkanes (C 21 –C 33 odd carbon numbered n-alkanes) were measured in the Hani peat sequence from northeast China. These data were compared with lipid biomarker compositions to assess changes in local vegetation and paleoclimate for the last 16ka. The δ 13 C values of n-alkanes range between −36.6 and −30...
