This data release includes physical and chemical data for samples from upland-source and streambank sampling sites in the Black Creek basin, Indiana. Data include total nitrogen and carbon concentrations, carbon species, total concentrations for 42 metals, and particle-size analysis. Source samples were identified as one of five land-use types: active cropland (corn, soybean, hay, and wheat), active horse pasture, roads, preserved forest, and streambanks of agricultural and non-agricultural channels. Source data were collected in August and September 2017. These data are used for source attribution in order to quantify the proportional contribution of individual sources to suspended sediment in the basin [Williamson et al. in prep].

This data release includes physical and chemical data for samples from fluvial targets (streambed and suspended sediment) from three sampling sites in the Black Creek basin, Indiana. Data include total nitrogen and carbon concentrations, carbon species, total concentrations for 42 metals, and particle-size analysis. Fluvial-target samples include both soft, streambed sediment and streamflow-integrated, monthly, suspended-sediment samples for water year 2018. These data are used for source attribution in order to quantify the proportional contribution of individual sources to suspended sediment in the basin [Williamson et al. in prep].

This data release includes chemical data for samples from upland-source and streambank sampling sites in the Black Creek basin, Indiana. Data include concentrations for 20 elements, extracted by Mehlich-3 extraction. Source samples were collected in August and September 2017 and analyzed in 2019.

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.

Data include total nitrogen and carbon, carbon species, total metal, and particle-size analyses of soft streambed from the Black Creek basin, Allen County, Indiana that was collected in July 2019. These data will be used in a sediment-source mixing model in order to attribute the proportional contribution of individual sources to suspended sediment in the basin. Source samples were identified as one of five land-cover types: cropland (corn, soybean, hay, and wheat; sites included a mix of conventional and conservation tillage), active horse pasture, roads, preserved forest, and streambanks along agricultural and non-agricultural channels. Source data were collected in August 2017 (Williamson and others, 2020).

This data release includes physical and chemical data for samples from suspended and bottom sediments of streams in Minnesota. Data were collected in September 2011 and April 2012. These data include total nitrogen and carbon, organic carbon, concentrations for 39 metals, and particle-size analysis. Source samples were grouped into one of three land-use categories: channel (Mid-bank,Low-bank), cropland (corn, sugar beets, soybeans, bare field), or road. These data were used for source attribution in order to quantify the proportional contribution of individual sources to suspend sediment in the basin.
