    • Visible and near-infrared spectroscopy for sediment samples collected across North-eastern U.S.

    Metadata Updated: November 26, 2025

    This data record contains a CSV file with spectral reflectance (420-2114 nm) for sediment samples collected from each of four source locations (cropland, stream bank, glaciolacustrine, and street dust) located across sites in the Northwestern US during prior studies. Data were collected in a laboratory setting using Spectrecology USB4000-VIS-NIR and NIRQuest512-2.2 spectrometers. The data contain spectra collected from sieved, non-sieved, dry and suspended samples from each sample source, as well as spectra for calibration standards. Explanation of fields in contained in the spectral properties data table are described in a data dictionary. Data on the physical properties of samples used in this study have been collected and are summarized in this data release.
