Survey of velocity at cross sections in the Chicago Sanitary and Ship Canal near Sag Junction, Chicago, IL (December 7, 2010)

These data were collected using a 1200 kHz TRDI Rio Grande acoustic Doppler current profiler (ADCP) in mode 12 with 25 centimeter bins from a moving boat. The data were georeferenced with a Hemisphere Crescent A100 differential Global Positioning System (GPS) receiver with submeter accuracy. The data were processed in the Velocity Mapping Toolbox (Parsons and others, 2013) to obtain a mean velocity field for each cross section from four individual transects at each cross section. These data were collected by the U.S. Geological Survey (USGS) concurrently with environmental DNA (eDNA) sampling in this reach of the Chicago Sanitary and Ship Canal (CSSC) by the U.S. Fish and Wildlife Service (USFWS). NOTE: Any data assigned a value of "-9999" are bad or missing data and should not be used for analysis. Parsons, D. R., Jackson, P. R., Czuba, J. A., Engel, F. L., Rhoads, B. L., Oberg, K.
