This data release contains acoustic Doppler current profiler (ADCP) data used in generating a model of sediment flux through Carquinez Strait, CA at Benicia Bridge. The ADCP outputs binary data files containing measurement scheme, location, time, velocity, backscatter, boat heading, depth, and other parameters. There are two forms of data provided, one collected from two transects along the western side of Benicia Bridge and one collected with two stationary, upward-looking ADCPs deployed on the bed 300 m seaward of Benicia Bridge. These data are provided in ".csv" format for the transect data, and ".dat" format for the upward-facing data, as described in the READMEforCSV.txt and READMEforDAT.txt files associated with this data release.

This dataset contains a series of processed acoustic Doppler current profiler (ADCP) measurements collected by boat on the Missouri River at Searcys Bend near Columbia, Missouri on May 5, 2021, during a dye release experiment at the site. The data presented here have been processed with the Velocity Mapping Toolbox (VMT) and combined into a single shapefile using ArcGIS. The dataset was collected to validate a multidimensional hydrodynamic model.

This dataset records results from a bottom-deployed upward-looking Acoustic Doppler Current Profiler (ADCP, 600 kHz Workhorse Monitor, Teledyne RD Instruments, Poway, California) deployed during the summer of 2019 (late June until early August) near Hammond Bay, Lake Huron (45.5948 degrees north, -84.1542 degrees east). Data were collected in support of nearby Cladophora and benthic algal assessments, as well as to validate hydrodynamic modeling.

Water velocities were measured in the Calumet Harbor for 5 dates in 2015 and 2016 using Teledyne Rio Grande 600 kHz acoustic Doppler current profilers (ADCP). The data were georeferenced with differential GPS receivers with submeter accuracy. These velocity data were collected in cooperation with the US Army Corps of Engineers-Chicago District. ADCP data were collected on the following dates and for the following purposes: May 12, 2015: Water velocities in the Calumet Harbor and Calumet River. Unsteady discharges in the Calumet River mouth. September 9, 2015: Water velocities in the Calumet Harbor and Calumet River mouth. October 5, 2015: Water velocities in the Calumet Harbor and Calumet River mouth. March 25, 2016: Water velocities in the Calumet Harbor and Calumet River mouth. May 6, 2016: Water velocities in the Calumet Harbor and Calumet River mouth. Datasets were processed using the Velocity Mapping Toolbox (Parsons and other, 2013) to derived temporally- and spatially-average water velocity values for each survey data.

Acoustic doppler current profiling (ADCP) data was collected to describe streamflow characteristics including total streamflow, velocity magnitude and secondary flow structure, and backscatter intensity at 29 cross-sections at the Myrtle Creek Bend on the Kootenai River on June 3, 2013. Each of the 29 cross-sections consisted of 4 transects or bank-to-bank coverage to obtain a representative velocity pattern. The mean daily streamflow was around 35,500 cubic feet per second or 1,005 cubic meters per second.

This child item data set contains acoustic Doppler current profiler (ADCP) data collected during 2023 from an uplooking tripod in Sodus Bay (USGS station number 431533076582101). This data set includes the raw binary data files from the ADCPs as well as tabulated text files of echo intensity, backscatter, velocity, and ancillary data. Tables were created by processing raw data files in R-language oceanographic package OCE (Kelley and others, 2022) and TRDI WinRiver II (Teledyne RD Instruments, 2007). All aggregation, manual magnetic variation calculations, and post-processing were completed using Python libraries pandas (McKinney, 2010) and NumPy (Harris and others, 2020).

Field measurements of flow velocity and discharge were acquired from the Middle Channel of the St. Clair River delta, Michigan, May 2-4, 2022. The velocity and discharge measurements included in this data release were obtained using a SonTek M9 acoustic Doppler current profiler (ADCP) deployed from a boat with an outboard motor. River Surveyor Live software version 4.1. was used to acquire and store the ADCP files. The ADCP data were collected along 8 transects spanning the width of the Middle Channel; two passes across the channel were made at each transect. This data release provides text files derived from the raw ADCP data files using the Velocity Mapping Toolbox (VMT) software version 4.09. Text files with projected spatial coordinates, velocity components, and depth-averaged velocity magnitudes, were generated. The spatial location of each measurement was obtained using a Trimble 540AP Global Navigation Satellite System (GNSS) receiver and real time network (RTN). The map projection and datum for these data are UTM Zone 17 N and NAD 83, respectively. This data release consists of a series comma-delimited (*.csv) text files. Each file consists of five columns: UTM_Easting, in meters, UTM_Northing, in meters, EastDAV, in m/s, and NorthDAV, in m/s and Velocity magnitude, in m/s. The first two columns are the easting and northing spatial coordinates, respectively. The third and fourth columns are the easting and northing components of the depth-averaged velocity magnitude in meters per second. The fifth column is the velocity magnitude in meters per second. An additional text file is included that provides the average discharge at the cross-section or mean of the two ADCP passes made at each transect. This field-based data set was used to determine the discharge of the Middle Channel of the St. Clair River delta and to provide depth-averaged velocities to inform hydraulic models.

The dataset contains data collected with an acoustic Doppler current profiler (ADCP) for a reach of the Osage River downstream from Bagnell, Missouri. Velocity data were collected using a 600-kilohertz RiverRay acoustic Doppler current profiler (ADCP; Teledyne Marine RD Instruments, Poway, California) on March 3, 2022 and May 10, 2022. Position data were collected using a Trimble R2 Real Time Kinematic Global Navigation Satellite Systems (RTK GNSS) Receiver (Trimble, Westminster, Colorado) mounted directly above the ADCP. This data release consists of a) one shapefile with depth-averaged velocity magnitude and direction data and 12 text files that contain processed ascii velocity data for March 3, 2022 and b) one shapefile with depth-averaged velocity magnitude and direction data and 8 text files that contain processed ascii velocity data for May 10, 2022. Ascii velocity data were exported from WinRIver II ADCP software.
