Standardized element data of sediment core PG1972-1 from Lake Lake Bezrybnoe (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 PG1972, retrieved in 2009 from Lake Bezrybnoe (Lena Delta, Russia) at 4.7 m water depth. The thermokarst lake Bezrybnoe is small basin in tundra region and has one outflow and three inflows. It lies at an elevation of ca. 6 m a.s.l. with a surface area of ca. 0.77 km2 and a maximum lake water depth of estimated 5.3 m. The 1.08 m sediment core was retrieved by a UWITEC hammer action gravity corer (60mm) 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工作，旨在实现湖泊沉积物岩芯数据的机器可读与跨样本可比性。本次研究对2009年于俄罗斯勒拿河三角洲别兹里布诺耶湖（Lake Bezrybnoe）水深4.7米处采集的沉积物岩芯PG1972的X射线荧光线扫描（X-ray fluorescence line scanning, XRF）元素数据进行了标准化处理。别兹里布诺耶湖为热融喀斯特湖，是苔原区域的小型盆地，拥有1条出水口与3条入水口。该湖海拔约6米（a.s.l.，即海平面以上），表面积约0.77平方千米，最大水深预估为5.3米。本次采集的1.08米长沉积物岩芯，由UWITEC锤击式重力取样器（直径60mm）完成获取，采集工作隶属于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（AWI，德国波茨坦）与俄罗斯雅库茨克东北联邦大学（NEFU，俄罗斯雅库茨克）合作开展的"RU-Land_2009_Lena-transect"科考活动。岩芯垂向元素组成由不来梅港阿尔弗雷德·魏格纳研究所的AVAATECH X射线荧光岩芯扫描仪完成测定。
