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 PG2023, retrieved in 2010 from Lake Ozero Kyutyunda (Yakutia, Russia) at 2.9 m water depth. The thermokarst lake Ozero Kyutyunda is in an exorheic basin in the coniferous forest area and has one outflow, one inflow and several smaller inflows. It lies at an elevation of ca. 56 m a.s.l. with a surface area of ca. 4.9 km2 and a maximum lake water depth of estimated 3.5 m. The 7.1 m sediment core was retrieved by a UWITEC 60mm piston corer during the RU-Land_2010_Lena 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. ...
