    • Field Spectra from the upper Sacramento River in northern California, September 11-14, 2017

    Metadata Updated: January 20, 2026

    Field spectra were collected from a reach of the upper Sacramento River in northern California, September 11-14, 2017, to support research on remote sensing of rivers. Reflectance measurements were made from a boat near the confluence of Cottonwood Creek with the Sacramento River using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The depth at each spectral measurement location was interpolated from field measurements of depth obtained with an acoustic Doppler current profiler and an echo sounder. This data release provides both the reflectance spectra and the interpolated depths and can be used to develop relationships between depth and reflectance for mapping river bathymetry from field spectra or passive optical remotely sensed data.
