Acoustic Doppler current profiler (ADCP) data were collected at multiple transects spaced in a regular grid 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. R., Jackson, P. R., Czuba, J. A., Engel, F. L., Rhoads, B. L., Oberg, K. A., Best, J. L., Mueller, D. S., Johnson, K. K. and Riley, J. D. (2013),...

Bathymetric survey data of the Brandon Road Dam spillway was collected on May 27 and May 28, 2015 by the US Geological Survey (USGS) using Trimble Real-Time Kinematic Global Positioning System (RTK-GPS) equipment. The base station was set up over a temporarily installed survey pin on both days. This pin was surveyed into an existing NGS benchmark (PID: BBCN12) within the Brandon Road Lock property. In wadeable sections, a GPS rover with 2.0 meter range pole and flat-foot was deployed. In sections unable to be waded, a 2.0 meter range pole was fix-mounted to a jon boat, and a boat-mounted Acoustic Doppler Current Profiler (ADCP) was used to collect the depth data. ADCP depth data were reviewed in the WinRiver II...

Acoustic Doppler current profiler (ADCP) data were collected along a prescribed navigated course throughout Calumet Harbor on May 6, 2016 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. R., Jackson, P. R., Czuba, J. A., Engel, F. L., Rhoads, B. L., Oberg, K. A., Best, J. L., Mueller, D. S., Johnson, K. K. and Riley, J. D. (2013), Velocity Mapping Toolbox...

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 Trimble AG132 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 individual transects at each cross section. These data were collected in support of the US Army Corps of Engineers Great Lakes and Mississippi River Interbasin Study (GLMRIS), and were concurrent with a dye-tracing study. NOTE: Any data assigned a value of "-9999" are invalid or missing data and...

In 2016, the U.S. Fish and Wildlife Service, U.S. Geological Survey, and U.S. Army Corps of Engineers undertook a large-scale interagency field study to determine the influence of commercial barge vessels on the efficacy of the Electric Dispersal Barrier System (EDBS) in the Chicago Sanitary and Ship Canal (CSSC) in preventing fish passage. This study included a series of trials in which a tow, consisting of a tug vessel and six fully-loaded barges, transited the EDBS in both upstream-bound (n = 23) and downstream-bound (n = 22) directions. A 1,200 kHz Teledyne RDI Channel Master Acoustic Doppler Velocity Meter (ADVM) was mounted on the barge at the position of the rake-to-box junction. The ADVM faced outward from...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
