This data set is part of a larger data harmonization effort to make lake sediment core data machine readable and comparable. Here we standardized X-ray fluorescence line scanning (XRF)-based element data of sediment core PG1982, retrieved in 2009 from Lake 09-Tik-09 (Yakutia, Russia) at 4.7 m water depth. The thermokarst lake 09-Tik-09 is situated in the forest tundra and has one outflow an one inflow. It lies at an elevation of ca. 116 m a.s.l. with a surface area of ca. 0.383 km2 and a maximum lake water depth of estimated 6.3 m. The 1.28 m sediment core was retrieved by a UWITEC hammer action gravity corer during the RU-Land_2009_Lena-transect expedition of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI, Germany, Potsdam) in cooperation with the North Eastern Federal State University (NEFU, Russia, Yakutsk). The downcore elemental composition was measured using an AVAATECH x-ray fluorescence core scanner at AWI Bremerhaven.
