To validate the interpretations of multibeam sonar data and turn it into geologically and biologically useful information, the U.S. Geological Survey (USGS) towed a camera sled over specific locations throughout the Seattle map area to collect video and photographic data that would \u201cground truth\u201d the seafloor. The ground-truth survey conducted in the Offshore of Seattle map area occurred in 2011 on the R/V Karluk (USGS field activity K0111PS) and on the Washington State Department of Fish and Game R/V Molluscan (USGS field activity M0111PS). The underwater camera sled was towed 1 to 2 m above the seafloor at speeds of between 1 and 2 nautical miles/hour. The surveys for this map area include approximately 6 hours (9.1 trackline km) of video.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9GVRZ3M", "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.ae648166-29c0-48e7-b576-d8aedd94c386.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_ae648166-29c0-48e7-b576-d8aedd94c386", "keyword": ["CMHRP", "Coastal and Marine Hazards and Resources Program", "Island County", "King County", "Marine Habitat", "PCMSC", "Pacific Coastal and Marine Science Center", "Physical Habitats and Geomorphology", "Puget Sound", "Salish Sea", "Seattle", "State of Washington", "Substrate", "U.S. Geological Survey", "USGS", "USGS:ae648166-29c0-48e7-b576-d8aedd94c386", "biota", "ecosystems", "field observation", "fisheries", "geoscientificInformation", "marine habitat", "oceans", "sea-floor characteristics", "seabed", "video sled observations"], "modified": "2022-11-30T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-122.514976, 47.568494, -122.379062, 47.828367", "theme": ["geospatial"], "title": "Underwater video observations offshore of Seattle, Washington"}
