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.663a5123d34e77890839b03f.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_663a5123d34e77890839b03f", "keyword": ["Distributions", "Harrison Bay", "Shoreline", "Coastal and Marine Hazards and Resources Program", "United States of America", "Digital Shoreline Analysis System", "geospatial datasets", "Kuparuk River", "Staines River", "USGS:663a5123d34e77890839b03f", "U.S. Geological Survey", "USGS", "coastal processes", "CMHRP", "Shoreline change", "environment", "State of Alaska", "DSAS", "Canning River", "Physical/Chemical Features", "Beaufort Sea", "ANWR", "Colville River", "oceans", "Arctic National Wildlife Refuge", "Pacific Coastal and Marine Science Center", "geoscientificInformation", "Sagavanirktok River", "Prudhoe Bay", "North Slope", "shoreline erosion", "PCMSC", "shoreline accretion", "Arctic"], "modified": "2024-09-11T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-150.231338, 69.963952, -144.137837, 70.517392", "theme": ["geospatial"], "title": "Digital Shoreline Analysis System (DSAS) version 5.1 transects with long-term linear regression rate calculations for the sheltered central Beaufort Sea coast of Alaska from the Hulahula River to the Colville River"}
