A 400-meter reach was surveyed using a Humminbird Helix sonar system. Proprietary sonar data were converted to PNG image files (i.e., rectified and speed-corrected) using SonarTRX Pro. The resulting data set includes one CSV file, original side-scan sonar images (PNG files), speed corrected side-scan images (correcting distortions in imagery due to small changes in boat velocity; PNG files), and a KMZ file of original rectified images for a mosaic display in Google Earth Pro.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13DNT2S", "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.68934c9ad4be0244121fbe1c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_68934c9ad4be0244121fbe1c", "keyword": ["Creve Coeur Lake", "Missouri", "Saint Louis County", "USGS:68934c9ad4be0244121fbe1c", "animal behavior", "biota", "fish", "fishery management", "invasive species", "population and community ecology", "side-scan sonar", "sonar methods"], "modified": "2025-08-06T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-90.49232, 38.70695, -90.47646, 38.72543", "theme": ["geospatial"], "title": "Consumer-Grade Side-Scan Sonar Imagery of Invasive Silver Carp in a Missouri River Oxbow Lake, Creve Coeur Lake, 2023 September 20"}
