Standardized element 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 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.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年从俄罗斯雅库特地区09-Tik-09湖（水深4.7米）获取的PG1982号沉积物岩芯的X射线荧光（X-ray fluorescence, XRF）元素扫描数据进行了标准化处理。该热喀斯特湖09-Tik-09坐落于森林苔原带，拥有一条入湖径流与一条出湖径流，湖面海拔约116米，表面积约0.383平方千米，最大水深约6.3米。研究团队采用UWITEC锤击式重力岩芯取样器，于阿尔弗雷德·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，德国波茨坦）联合俄罗斯东北联邦大学（North Eastern Federal State University, NEFU，俄罗斯雅库茨克）开展的RU-Land_2009_Lena-transect科考航次中，获取了总长1.28米的沉积物岩芯。岩芯的垂向元素组成通过不来梅港AWI实验室的AVAATECH X射线荧光岩芯扫描仪完成测定。
