Chemical and physical data for sediment source tracking in Little Flatrock Creek, Ohio - source samples, 2021

Data include total nitrogen and carbon, carbon species, total metal, and particle-size analyses of soft streambed sediment from Little Flatrock Creek, Paulding County, Ohio. These data will be used in a sediment-source mixing model to attribute the proportional contribution of individual sources to suspended sediment in the basin. Source samples were identified as one of four land-cover types: cropland (corn, soybean, hay, and wheat; sites included a mix of conventional and conservation tillage), roads, preserved forest, and streambanks along agricultural and non-agricultural channels.

本数据集包含美国俄亥俄州保丁县小弗拉特罗克溪（Little Flatrock Creek）软质河床沉积物的多项分析数据，具体涵盖总氮(total nitrogen)、总碳(total carbon)、碳组分(carbon species)、全金属(total metal)含量以及粒度分析(particle-size analyses)结果。此类数据将被应用于沉积物源混合模型(sediment-source mixing model)，以定量归因流域内悬浮沉积物(suspended sediment)各来源的相对贡献占比。沉积物源样本被划分为四类土地覆盖类型(land-cover types)：农田(cropland)（种植玉米、大豆、干草与小麦，采样点涵盖传统耕作与保护性耕作(conservation tillage)的混合模式）、道路、保护林(preserved forest)，以及农业与非农业河道沿岸的河岸带。
