The velocity measurements included in this data release were obtained using a TRDI RiverPro acoustic Doppler current profiler (ADCP) deployed from a boat with an outboard motor. These data were collected along 15 cross-sections on the Yukon River and 17 cross-sections on the Tanana River. This data release provides depth-averaged flow velocities derived from the raw ADCP data using the TRDI WinRiver II processing software. The spatial location of each measurement was obtained using a Hemisphere A101 differential GPS mounted on the RiverPro instrument. The map projection and datum for these data are UTM Zone 6 N and NAD 83, respectively. This data release includes tab-delimited (*.txt) text files consisting of seven columns: xsID, UTM_Zone_6N_East_m, UTM_Zone_6N_North_m, Depth_m, Velocity_East_Component_m_per_s, Velocity_North_Component_m_per_s, and Date. The first column is an integer identifying the cross section, the next two columns are the easting and northing spatial coordinates, respectively, the fourth column is the water depth in meters, the fifth column is the east component of the depth-averaged velocity magnitude in meters per second, the sixth column is the north component of the depth-averaged velocity magnitude in meters per second, and the seventh column is the date the measurement was collected.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P14JQAWD", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.6917b862d4be023233bb135c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6917b862d4be023233bb135c", "keyword": ["AK", "Alaska", "Remote sensing", "Tanana River", "USA", "USGS:6917b862d4be023233bb135c", "Yukon Flats National Wildlife Refuge", "Yukon River", "acoustic Doppler current profiler (ADCP)", "depth", "flow velocity", "river"], "modified": "2026-03-27T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-149.8975, 63.8697, -145.3766, 66.0894", "theme": ["geospatial"], "title": "Field measurements of flow velocity and depth from the Yukon and Tanana Rivers, collected July 1-3, 2025"}
