These maps were derived from interpretations of seismic-reflection profiles, high-resolution bathymetry, acoustic-backscatter intensity, bottom photographs, and surficial sediment samples. The interpretation of the seismic stratigraphy and mapping of glacial and Holocene marine units provided a foundation on which the surficial maps were created. This mapping is a result of a collaborative effort between the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management to characterize the surface and subsurface geologic framework offshore of Massachusetts.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://pubs.usgs.gov/of/2016/1119/ofr20161119_data_catalog.html", "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.59991edf-a3d0-401b-a68a-065b9099d263.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_59991edf-a3d0-401b-a68a-065b9099d263", "keyword": ["U.S. Geological Survey Open-File Report 2006-1357", "USGS:59991edf-a3d0-401b-a68a-065b9099d263", "imageryBaseMapsEarthCover", "Woods Hole Coastal and Marine Science Center", "backscatter", "geospatial datasets", "Aquinnah", "CZM", "Nashawena Island", "sidescan", "Coastal and Marine Geology Program", "Cape Poge", "Nantucket Sound", "USGS", "Cuttyhunk Island", "mosaic", "Menemsha", "Middle Ground Shoal", "marine geophysics", "Succonnesset Shoal", "Lucas Shoal", "Elizabeth Islands", "L'Hommedieu Shoal", "Klein 5000", "Massachusetts Office of Coastal Zone Management", "U.S. Geological Survey Open-File Report 2012-1006", "U.S. Geological Survey Open-File Report 2009-1001", "Martha's Vineyard", "image mosaics", "oceans", "Vineyard Sound", "sidescan sonar", "Cape Cod", "U.S. Geological Survey Open-File Report 2013-1020", "Oak Bluffs", "composite image", "grey scale", "Nonamesset Island", "GeoTIFF", "Falmouth", "Succonnesset Point", "Woods Hole", "U.S. Geological Survey Open-File Report 2012-1002", "U.S. Geological Survey", "WHCMSC", "Hedge Fence Shoal", "Edgartown", "CMGP", "Vineyard Haven", "sea-floor acoustic reflectivity", "U.S. Geological Survey Open-File Report 2011-1184", "Klein 3000", "Hydrographic Survey H11319", "Squash Meadow Shoal", "Naushon Island", "Gosnold", "Atlantic Ocean", "geoscientificInformation", "Pasque Island", "U.S. Geological Survey Open-File Report 2008-1004"], "modified": "2024-03-18T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-71.034883, 41.318511, -70.428524, 41.541741", "theme": ["geospatial"], "title": "1-m backscatter mosaic in Vineyard and western Nantucket Sounds produced from multiple sidescan-sonar datasets (GeoTIFF Image; UTM, Zone 19N, WGS 84)"}
