Characterized by low river discharge and significant human impact, the harbor is typical of many bays and estuaries along the New England coast.  The sands and gravels that floor Massachusetts Bay and the Harbor approaches are relict glacial sediments. However, fine-grained sediments are accumulating in areas of lower energy.", "distribution": [{"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.704894bf-6080-43a4-abae-0f6337e1379f.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "accessURL": "http://pubs.usgs.gov/of/2003/of03-001/htmldocs/data.htm", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_704894bf-6080-43a4-abae-0f6337e1379f", "keyword": ["Massachusetts Bay", "point shapefile", "Gulf of Maine", "USGS:704894bf-6080-43a4-abae-0f6337e1379f", "Open-File Report 03-001", "location", "GIS", "geospatial datasets", "navigational data", "Coastal and Marine Geology Program", "texture", "U.S. Geological Survey", "surficial classification", "Boston Harbor", "USGS", "CMGP", "sediment classification", "points", "U.S. Atlantic East Coast", "sea-floor characteristics", "sedimentary environment", "Geographic Information System", "oceans", "geoscientificInformation", "marine geology"], "modified": "2021-11-16T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-70.878820, 42.121880, -70.599270, 42.564340", "theme": ["geospatial"], "title": "Boston Harbor and approaches samples (WILLETT72 shapefile"}
