Pollen and spores in massive ice, snow, sea ice and ice wedges


Palynologic analyses were carried out in Holocene massive ice, snow and ice wedges from sampling locations at the Yamal peninsula and the Yamal Nenets region in Siberia.

Sample processing for the palynologic analyses included KOH deflocculation, treatment with HF (except for the samples of pure ice without ground or low concentration of ground particles) and mounting of pollen samples in glycerine. To simplify the process and prevent pollen loss, the samples were not subjected to either acetolysis. Cytoplasm in the pollen grains is not chemically removed, which allowed us to separate fresh pollen grains and reworked ones. Pollen percentages calculate based on the total pollen and spore sum.Data was submitted and proofread by Yurij K Vasil'chuk and Lyubov Bludushkina at the faculty of Geography, department of Geochemistry of Landscapes and Geography of Soils, Lomonosov Moscow State University.Funding was received from the Russian Science Foundation (Award nr. 19-17-00126, field research) and the Russian Foundation for Basic Research (Award nr. 18-05-60272, isotope analysis).
