Pollen data for 72 sites in East Siberia

A total of 72 surface samples were collected from Chukotka and Yakutia in East Siberia in the Russian-German Cooperation Expeditions to Siberia in 2016 and 2018: 10 lake surface samples were collected in July 2016, 48 moss/soil polsters and 14 lake sediment samples in July and August 2018. Coordinates of the sampling sites were obtained by hand-held Global Positioning System (GPS). The altitudes of the sampling sites range from 94 to 843 m above sea level. At least 300 terrestrial pollen grains were counted and identified in each sample under a microscope at 400X using published pollen atlases and identification keys. Pollen percentages were calculated based on the total number of terrestrial pollen grains. Ecoregions, including Floodplain and Anthropogenic Meadows, Mountain Tundra, Open Woodlands and Middle Taiga, of each sampling site were extracted from a 1:4 million scale vegetation map for the land area of the former Soviet Union.
