The approximate location of the saltwater interface is represented by the 1,000-mg/L isochlor at the base of the Biscayne aquifer. The term \u201capproximate\u201d is used here because certain areas of the map lack sufficient spatial distribution of monitoring wells to create a precise representation. The approximate location of the 1000-mg/L isochlor was identified using chloride concentrations and specific conductance data from groundwater wells. These data are provided in the child item, \"Summary tables for the approximate inland extent of saltwater intrusion at the base of the Biscayne aquifer in 2022, Miami-Dade County, Florida\".", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P13TSEEA", "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.6644e424d34e1955f5a42ae4.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6644e424d34e1955f5a42ae4", "keyword": ["Biscayne aquifer", "Florida", "Miami-Dade County", "USGS:6644e424d34e1955f5a42ae4", "isochlor", "monitoring well", "saltwater interface", "saltwater intrusion"], "modified": "2025-12-10T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-80.5299, 25.3245, -80.1649, 25.9775", "theme": ["geospatial"], "title": "Shapefile for the approximate inland extent of saltwater intrusion at the base of the Biscayne aquifer in 2022, Miami-Dade County, Florida"}
