High-resolution pollen record of the last 13,500 years derived from AMS radiocarbon dated sediments of Lake Ochaul in Cis-Baikal (Eastern Siberia)


A 260-cm-long section of a sediment core from Lake Ochaul (54°14'N, 106°28'E; 641 m a.s.l.), a freshwater lake in the Cis-Baikal region, ca. 100 km northwest of Lake Baikal, was analysed for pollen and non-pollen palynomorphs. This high-resolution AMS-dated record covers the Lateglacial and Holocene interval between ca. 13,500 cal yr BP and the present. A total of 84 samples from the Och18-II-1 and Och18-II-2 sections have been treated using dense media separation to extract pollen and non-pollen palynomorphs (e.g. fern and moss spores, Chironomidae remains, Botryococcus and Pediastrum green algae colonies) for further microscopic analysis.
