Spatial distribution of layer-averaged velocity measured in the Calumet Harbor, Illinois (September 14, 2015)

Acoustic Doppler current profiler (ADCP) data were collected along a prescribed navigated course throughout Calumet Harbor on September 14, 2015 to determine the spatial distribution of layer-averaged velocities. The data were layer-averaged in 2-foot increments of depth from the bed to the water surface, and temporally-averaged over a 30-second window to reduce noise. Data were processed using the Velocity Mapping Toolbox (Parsons and other, 2013). Any data assigned a value of "-9999" are invalid or missing and should not be used for analysis. Parsons, D.
