This data set contains radiocarbon age data of sediment core PG1746 from Lake Temje (Yakutia, Russia). Lake Temje (62°03′ N, 129°29′ E) is a thermokarst lake located 13 km east of Yakutsk on the Magane Terrace, west of the Lena River at ca. 208 m a.s.l. The lake is shallow, with a maximum depth of 75 cm and no permanent inflows and outflows. The 3.8 m lake sediment core PG1746 was recovered as part of a joint Russian-German 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) to Yakutia in July 2004. Sampling was performed from two connected rubber boats in the central part of Lake Temje at 70 cm water depth with a rod-operated half-tube corer (Russian peat corer: 5 cm in diameter, 100 cm long sampler). Overlapping core sections yielded a 380-cm-long sediment-core sequence. The core sections were described and sampled at 5-cm intervals in the field. Five ...
