This closure restricted vessel traffic along the river and potentially changed habitat characteristics for aquatic vegetation establishment and growth. To assess if patterns of vegetation establishment and growth changed during the closure, peak biomass imagery from 2019 (pre closure) and 2021 (post closure) were compared for a vegetation response. This assessment found locations where aquatic vegetation increased and locations where aquatic vegetation decreased.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P95VWUF9", "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.637e417bd34ed907bf764f13.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_637e417bd34ed907bf764f13", "keyword": ["Illinois", "Illinois River", "Illinois Waterway", "USGS:637e417bd34ed907bf764f13", "aerial photography", "aquatic biology", "aquatic ecosystems", "biota", "environment", "freshwater ecosystems", "geospatial datasets", "habitats", "image analysis", "land use and land cover", "scientific interpretation", "vegetation", "wetland ecosystems"], "modified": "2023-05-08T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-90.5347, 39.8833, -88.0769, 41.6472", "theme": ["geospatial"], "title": "Locations of Change in Aquatic Vegetation Cover along the Illinois Waterway from 2019 - 2021"}
