Chemical and Physical Data for Sediment Source and Fluvial Target Samples for Fingerprinting of Suspended and Bed Sediment in Medicine Creek, Missouri and Iowa

This data release includes physical and chemical data for samples from upland sources, eroding banks, streambed deposits, and suspended sediment in the Medicine Creek watershed, Missouri and Iowa. Samples were collected from July 2020 to June 2022. Data include total nitrogen and carbon concentrations, particle size analysis, stable isotope ratios, and concentrations of 49 mineral elements. These data are used for sediment fingerprinting to apportion relative contribution of sources in target fluvial samples, especially differentiation between bank erosion and upland sources. Source samples included streambank samples and upland soil samples, which were grouped by land-use category: crop, pasture, or forested. Target samples included suspended sediment collected with passive samplers and bed material collected specifically from fine-grain depositional areas, if present, within a stream reach.
