The sediment core from a lake located at 72.40°N and 102.29°E; 60 m a.s.l., was analysed on its fossil pollen spectra. The lake is elliptic in shape with a surface area of around 2.4 hectares and a mean radius of 100 m (maximum depth = 14.3 m). The lake is located in a confined depression on a low-lying plateau in the northern lowlands. It has no inflow streams but drains the surrounding ridges. Sampling took place at a central lake position at 14.3 m depth, where a 131.7 cm-long core was retrieved using a UWITEC gravity corer extended with a hammer action. ...
