Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 5.1, an ArcGIS extension developed by the U.S. Geological Survey. Long-term rates of shoreline change were calculated using a linear regression rate-of-change method based on available shoreline data between 1947 and 2017. A reference baseline was used as the originating point for the orthogonal transects cast by the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate long-term rates.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/F72Z13N1", "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.663a56c4d34e77890839b06b.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_663a56c4d34e77890839b06b", "keyword": ["Distributions", "Shoreline", "Coastal and Marine Hazards and Resources Program", "United States of America", "Digital Shoreline Analysis System", "geospatial datasets", "U.S. Geological Survey", "USGS", "coastal processes", "CMHRP", "Shoreline change", "Hulahula River", "Kaktovik", "environment", "State of Alaska", "DSAS", "USGS:663a56c4d34e77890839b06b", "Physical/Chemical Features", "Barter Island", "Beaufort Sea", "ANWR", "oceans", "Arctic National Wildlife Refuge", "Demarcation Bay", "Pacific Coastal and Marine Science Center", "geoscientificInformation", "Jago River", "North Slope", "Okpilak River", "shoreline erosion", "PCMSC", "shoreline accretion", "Arctic"], "modified": "2024-09-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-143.990143, 69.627939, -141.201885, 70.138283", "theme": ["geospatial"], "title": "Digital Shoreline Analysis System (DSAS) version 5.1 transects with long-term linear regression rate calculations for the sheltered eastern Beaufort Sea coast of Alaska from the U.S. Canadian Border to the Hulahula River"}
