To support an investigation of the feasibility of measuring river bathymetry using remotely sensed data, remotely sensed bathymetry and field measurements were collected on the Colorado River near Lees Ferry, AZ on September 23, 2019. The data in this release include optical measurements using the following sensors: WET Labs ECO, and WET Labs ac-s. 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.
