    dct:description "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]." ;
