LpPb and dPb dataset for 'Glacier-derived particles as a regional control on marine dissolved Pb concentrations'

The file contains labile particulate Pb (LpPb) contents of selected sediment samples from Svalbard and Greenland areas, and variation of dissolved Pb (dPb) concentrations in resonse to different conditions of sediment load, inubation time and temperatures during incubation of these sediments in aging seawater. LpPb for sediment samples was determined following a 2 hour weak acid leach (Berger et al., 2008). dPb concentration was determined as per Rapp et al., (2017) with calibration via standard addition. This dataset is submitted for Jana Krause, Xunchi Zhu, Juan Höfer, Eric P. Achterberg, Anja Engel, Lorenz Meire, Alice E. Stuart-Lee, Mark J. Hopwood*, Glacier-derived particles as a regional control on marine dissolved Pb concentrations.

本数据集包含采自斯瓦尔巴（Svalbard）与格陵兰（Greenland）区域的选定沉积物样品中的不稳定颗粒态铅（labile particulate Pb, LpPb）含量，以及这些沉积物在陈化海水（aging seawater）中培养时，溶解态铅（dissolved Pb, dPb）浓度随沉积物负荷、培养时长与培养温度等不同条件的变化规律。沉积物样品中的LpPb含量参照Berger等人2008年的方法，通过2小时弱酸浸提进行测定；dPb浓度则按照Rapp等人2017年的方法，采用标准加入法进行校准后测定。本数据集由Jana Krause、朱训驰（Xunchi Zhu）、Juan Höfer、Eric P. Achterberg、Anja Engel、Lorenz Meire、Alice E. Stuart-Lee、Mark J. Hopwood*提交，用于其研究论文《冰川衍生颗粒物对海洋溶解态铅浓度的区域调控作用》（英文原标题：Glacier-derived particles as a regional control on marine dissolved Pb concentrations）。
