The report includes a detailed geophysical log, structure contour maps, hydrogeologic sections, and hydrographs of water levels in selected wells. The potentiometric surface-map can be used for determining direction of ground-water flow, hydraulic gradients, and the effects of withdrawals on the aquifer.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5ca2dd00e4b0b8a7f6317667.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F7CN7348", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5ca2dd00e4b0b8a7f6317667", "keyword": ["groundwater", "downdip limit", "Louisiana", "western extent", "USGS:5ca2dd00e4b0b8a7f6317667", "Mississippi Embayment", "potentiometric surface", "Sparta aquifer"], "modified": "2022-12-01T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-93.57533374, 31.863455618, -91.731228613, 33.040048984", "theme": ["geospatial"], "title": "Digitized Contours from Georeferenced Plate 1996 from \"Louisiana Ground-Water Map No. 13: Hydrogeology and Potentiometric Surface of the Sparta Aquifer in Northern Louisiana, October 1996\" (Brantly, Seanor, and McCoy 2002)"}
