Annual surveys were conducted from 1997-2002 and then some transects surveyed again in 2017-18.  Changes and patterns observed were reported on in 2003 for the 1997-2002 data, and a report summarizing changes and patterns from 1997-2017 will be reported on at this time. Several variables are recorded each survey year and placed into an Excel spreadsheet. The spreadsheets are read with a SAS program to generate a SAS dataset used in SAS programs to determine rates, depth loss, and associations between depth and change through regression.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9D467M3", "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.5fb53682d34eb413d5e139c6.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5fb53682d34eb413d5e139c6", "keyword": ["Erosion", "Mississippi River", "Navigational Pool", "Sedimentation", "USGS:5fb53682d34eb413d5e139c6", "Upper Mississippi River", "biota", "none"], "modified": "2021-06-10T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-157.14843749732, 9.7519389317733, -47.460937501698, 71.951642087008", "theme": ["geospatial"], "title": "Backwater Sedimentation in Navigation Pools 4 and 8 of the Upper Mississippi River"}
