Description of suspended sediment and soil samples database: measured properties associated metadata

From the perspective of open science, this dataset includes data and metadata of soil and suspended sediment samples collected across three catchments in Martinique (French West Indies) : Galion river catchment, Lézarde river catchment and Salée river catchment. During one year (June 2022 - July 2023), suspended sediment samplers were installed in the three river networks. In order to determine the signature of the potential erosion sources, soil samples were collected across the three catchments. In order to quantify suspended sediment source contributions and chlordecone contamination of suspended matter transiting in river, a set of different properties were measured in soil and suspended sediment samples: radionuclide activities, carbon and nitrogen isotopes, elemental geochemistry, visible colorimetry, chlordecone and its degradation products concentrations从开放科学（Open Science）视角出发，本数据集涵盖采自法属西印度群岛马提尼克岛三处流域的土壤与悬浮沉积物样品及其元数据，包括加里昂河（Galion river）流域、莱扎尔德河（Lézarde river）流域与萨莱河（Salée river）流域。在2022年6月至2023年7月的一年监测周期内，研究团队在上述三处河网中布设了悬浮沉积物采样器。为明确潜在侵蚀源的特征指纹，研究人员在三处流域内采集了土壤样品。为量化悬浮沉积物的来源贡献占比以及河道中迁移悬浮颗粒物的十氯酮（chlordecone）污染水平，研究团队对土壤与悬浮沉积物样品测定了多项指标：放射性核素活度、碳氮同位素组成、元素地球化学特征、可见光比色检测结果，以及十氯酮及其降解产物的浓度。
