Standardized radiocarbon data of sediment core PG1982 from Lake 09-Tik-09 (Yakutia, Russia)

This data set is part of a larger data harmonization effort to make lake sediment core data machine readable and comparable. Here we standardized radiocarbon age 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). Radiocarbon samples have been analysed at the Poznan radiocarbon laboratory and in Kiel.

本数据集隶属于一项更大规模的数据标准化整合项目，旨在实现湖泊沉积物岩芯数据的机器可读化与跨样本可比性。本次研究对2009年于俄罗斯雅库特地区09-Tik-09湖（水深4.7米）采集的PG1982号沉积物岩芯的放射性碳年龄数据开展了标准化处理。该热融喀斯特湖（thermokarst lake）09-Tik-09地处森林苔原带，拥有一条入湖径流与一条出湖径流，海拔约116米（海平面基准面），表面积约0.383平方千米，最大估算水深达6.3米。1.28米长的沉积物岩芯由UWITEC锤击式重力取样器（UWITEC hammer action gravity corer）采集，采集工作依托德国波茨坦阿尔弗雷德·魏格纳研究所-亥姆霍兹极地与海洋研究中心（Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, AWI）与俄罗斯雅库茨克东北联邦大学（North Eastern Federal State University, NEFU）合作实施的RU-Land_2009_Lena-transect科考项目完成。放射性碳样品分别于波兹南放射性碳实验室与基尔实验室完成分析。
