Small areas containing priority mussel habitat had additional collection efforts to map water velocities and bottom composition. Combining these data in a GIS can provide key components to characterizing physical benthic habitat for native mussels in a riverine environment. This information is highly desired by the National Park Service to more accurately assess environmental factors that influence native mussel distribution. The collaborative effort was funded by the Legislative-Citizen Commission on Minnesota Resources (LCCMR) Environment and Natural Resources Trust Fund (ENRTF), to help maintain and enhance Minnesota\u2019s environment and natural resources.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9BYGUQL", "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.6165b5cad34eb58ff6a152e5.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6165b5cad34eb58ff6a152e5", "keyword": ["Benthic/Attached Biota", "Minnesota", "Mississippi River", "National Park", "Physical Habitats and Geomorphology", "USGS:6165b5cad34eb58ff6a152e5", "Wisconsin", "acoustic doppler current profiling", "bathymetry", "benthic ecosystems", "freshwater ecosystems", "hydrologic characteristics of habitats", "image mosaics", "multibeam sonar", "river systems", "sidescan sonar", "spatial characteristics of habitats", "stream discharge"], "modified": "2026-04-30T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-93.1962, 44.8933, -93.1474, 44.9068", "theme": ["geospatial"], "title": "Mississippi National River and Recreation Area, ADCP Flow Diffusion of the Mississippi River near Hidden Falls, MN, 20190829"}
