Optical and sediment measurements collected from the Colorado River, near Parshall, Colorado, June 13, 2019

To support an investigation of the feasibility of measuring river bathymetry using remotely sensed data acquired from a small unmanned aircraft system (sUAS), remotely sensed bathymetry and field measurements were collected from two cross-sections on Colorado River near Parshall, CO on June 13, 2019. The data in this release include optical measurements using the following sensors: WET Labs ECO, WET Labs ac-s, and LISST 100x. The WET Labs ECO provides measurements of turbidity and chlorophyll and colored dissolved organic matter concentration. The WET Labs ac-s provides information of the absorption and attenuation coefficients of the water sampled across a range of wavelengths. The LISST 100x provides information on the mean grain size of sediment in suspension and the concentration of suspended sediment.
