Dataset underlying the publication “Flood characteristics drive river-scale macroplastic deposition”

This dataset presents the data used in the publication “Flood characteristics drive river-scale macroplastic deposition”. This dataset is on macroplastic and other macrolitter sampled on floodplains along the IJssel and the Meuse rivers in the Netherlands. We sampled 23 locations between 25 January 2024 - 14 February 2024, following a winter flood event along the IJssel river. We include the observations from a sampling campaign conducted along the Meuse river, which sampled 25 locations between 22 July and 4 August 2021 (Hauk et al., 2023). In addition, we include observations conducted by the Schone Rivieren program, for lower flood magnitude and low-flood conditions, along the IJssel and the Meuse rivers. For the Meuse river, these include seven sampling campaigns, from fall 2018 to fall 2022. For the IJssel river, five sampling campaigns are included, from fall 2020 to fall 2023.

本数据集收录了发表于论文《洪水特征驱动河流尺度大型塑料沉积》（Flood characteristics drive river-scale macroplastic deposition）的相关实验数据。该数据集涵盖荷兰艾瑟尔河（IJssel）与默兹河（Meuse）沿岸洪泛区采集的大型塑料（macroplastic）及其他大型垃圾（macrolitter）样本。2024年1月25日至2月14日，针对艾瑟尔河冬季洪水事件，研究团队在23处采样点位完成了样本采集工作。本数据集同时纳入默兹河沿岸2021年7月22日至8月4日期间开展的25处采样点位观测数据，相关采样行动的成果已发表于Hauk等（2023）的研究中。此外，本数据集还收录了Schone Rivieren（洁净河流）项目针对艾瑟尔河与默兹河低洪水量级、低水位条件下的观测数据：其中默兹河区域涵盖2018年秋季至2022年秋季间的7次采样行动，艾瑟尔河区域则涵盖2020年秋季至2023年秋季间的5次采样行动。
