Description
Summary:This article extends the findings of our previous research “Preliminary reconstruction of climate changes and vegetation cover inferred from pollen study of the arctic lake bottom sediments from the southwestern part of the Yamal Peninsula” (G.R. Nigamatzyanova, N.M. Nigmatullin, B.I. Gareev, O.N. Tumanov, L.A. Frolova, 21st International Multidisciplinary Scientific GeoConference SGEM. 4 (2021) 415-421. https://doi.org/10.5593/sgem2021/4.1/s19.53) [1].The Late Holocene vegetation history of the southern part of the Yamal Peninsula was reconstructed using the pollen data obtained from bottom sediments of the tundra lake K1 (68°15.320′ N, 69°07.675′ E) near the Yerkuta research station in the Yerkuta River basin. A 30-cm-long sediment core was drilled during the expedition to the lake in 2014. A total of 15 samples were taken at 1-cm intervals for palynological analysis. To extract pollen grains, prior chemical treatment of the samples by the standard methods. The palynological dataset was exported in Excel sheets, one listing the raw pollen counts and the other containing the pollen percentages determined with respect to the total pollen counts for all taxa. The palynodiagram illustrating the variations in pollen and spore percentages with depth is given. These palynological records yield insight into the vegetation dynamics on the Yamal Peninsula in response to the climate forcing and may be of practical importance in regional syntheses of the vegetation history in the region.
