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.本数据集涵盖采自斯瓦尔巴（Svalbard）与格陵兰（Greenland）区域的选定沉积物样品的不稳定颗粒态铅（labile particulate Pb, LpPb）含量，以及将这些沉积物置于老化海水中培养时，溶解态铅（dissolved Pb, dPb）浓度随沉积物负载、培养时长与培养温度等不同条件变化的响应规律。沉积物样品中的不稳定颗粒态铅含量参照Berger等（2008）提出的方法，通过2小时弱酸浸提流程完成测定。溶解态铅浓度则依据Rapp等（2017）的方法测定，并采用标准加入法进行校准。本数据集配套于以下学术论文：Jana Krause、朱训驰（Xunchi Zhu）、Juan Höfer、Eric P. Achterberg、Anja Engel、Lorenz Meire、Alice E. Stuart-Lee、Mark J. Hopwood*，《冰川衍生颗粒对海洋溶解态铅浓度的区域调控作用》（Glacier-derived particles as a regional control on marine dissolved Pb concentrations）。
