Supplemental Material: Rb-Sr isochron method of sediment source fingerprinting reveals a fundamental shift in erosion in response to anthropogenic land use

Data tables for sediment core, bedrock, and glacial till Rb-Sr isotope ratios and elemental geochemistry. Supplemental text includes a discussion of elemental geochemistry, chemical weathering, and grain size analysis, and figures that include a comparison of sediment trace element and rare earth ratios with bedrock and glacial till (Figure S1), major element Harker diagrams (Figure S2), chemical weathering data (Figure S3), and grain size data (Figure S4).
