Pollen data of Lake El'gygytgyn sediments, core PG1351 (MIS 5e, 6, 7e, 8)

Pollen from sediment core PG1351 was analysed by Lozhkin et al. (2007), but there was no sediment left to sample the same core depths for Monosaccharide anhydrides (MA) analyses (doi:10.1594/PANGAEA.915603). Therefore, we sampled 19 of the 44 MA sample's core depths for parallel pollen analyses to enable a direct comparison of MA and pollen records without age bias. These new pollen samples were prepared using standard pollen preparation procedures as have been used previously for the El'gygytgyn sediments (Andreev et al., 2012).

Lozhkin等人（2007）已对沉积物岩芯PG1351中的花粉进行了分析，但该岩芯中已无剩余沉积物可供在相同深度取样以开展单糖酐（Monosaccharide anhydrides，MA）分析（doi:10.1594/PANGAEA.915603）。因此，我们从44个MA样本对应的岩芯深度中选取了19个进行平行花粉分析，以便在无年龄偏差的情况下对MA记录与花粉记录开展直接对比。这些新的花粉样本采用了此前用于El'gygytgyn沉积物分析的标准花粉制备流程（Andreev等人，2012）。
