Water chemistry of Lagrangian samplings of Inland Elbe 2021 (MOSES Hydrological Extremes)@en

Four sampling campaigns were performed in the middle part of River Elbe between Elster (river km 199) and Dömitz (km 506). Measurements were done at different seasons and discharge conditions in April, June, August, and October 2021. The sampling was conducted in a Lagrangian way according to travel time using the research vessel Albis. For each campaign, data files of the multiparameter probe and of waterchemical analyses are provided.本研究在易北河（River Elbe）中游段开展了四次采样作业，采样区间为河程199公里处的埃尔斯特（Elster）至河程506公里处的多米茨（Dömitz）。采样工作分别于2021年4月、6月、8月及10月进行，覆盖不同季节与径流条件。本次采样采用拉格朗日（Lagrangian）随流采样方案，依据水体行进时间规划采样位点，并依托科研船阿尔比斯号（Albis）完成全部作业。每次采样作业均配套提供多参数探头检测数据与水化学分析数据文件。
